　Subsequently to step S16, the number of pixels the vertical direction from the memory M21 camera 124 in step S17 reads, if the count value Y is less than or equal to the number vertical direction of the pixels of the camera 124 in step S18 (NO), to step S11 return, when the count value Y is larger than the number of vertical direction of the pixels of the camera 124 (YES), the process proceeds to step S19.
[0051]
　That is, in step S4 ~ step S18, a second step, in accordance with the rotational phase of the printing press captures an Kogire 1a of the first line (K = 1), and stores the captured image.
[0052]
　Step S19 is overwritten with 1 in the count value Y memory M17 for storing the overwrites 1 in the count value X memory M18 for storing in step S20, 1 overwrites the count value N memory M22 in step S21, step S22 in is overwritten with 1 in the count value M storage memory M23.
[0053]
　Subsequently, the captured image data memory M19 for storing in step S23 (X + M-1, Y + N-1) of the address location of the read pixel data, at step S24 of the reference mark pixel storage memory of M24 of (M, N) It reads the pixel data of the reference mark 1c address location.
[0054]
　Subsequently, equal to the pixel data of the address location (X + M-1, Y + N-1) is (M, N) of the reference mark 1c address location of the pixel data in step S25 (YES), the process proceeds to step S26. On the other hand, when the pixel data of the address location (X + M-1, Y + N-1) is different from (M, N) reference mark 1c of the pixel data of the address position (NO), the process proceeds to step S129 to be described later.
[0055]
　Step S26 to add 1 to the count value M in overwrites the count value M memory M23 for storing and, subsequently, reads the number of pixels the horizontal direction of the reference mark 1c from the memory 25 at step S27.
[0056]
　Then, if the count value M is less than or equal to the number of pixels the horizontal direction of the reference mark 1c in step S28 (NO), the process returns to step S23, When the count value M is larger than the number of pixels the horizontal direction of the reference mark 1c ( YES), it adds 1 to the count value N in step S29 overwrites the count value N memory M22.
[0057]
　Subsequently to step S29, if the number of pixels vertical direction of the reference mark 1c from the memory M26 read, the count value N is less than or equal to the number of pixels vertical direction of the reference mark 1c in step S31 in step S30 (NO), step returning to S22, If the count value N is larger than the number of pixels vertical direction of the reference mark 1c (YES), reads the count value X from the memory M18 in step S32.
[0058]
　Following step S32, the count value X in step S33, is stored in the X address direction position of the measurement position memory M27 for storing the reference mark as a measurement position in the X-direction of the reference mark 1c, from the memory M17 in step S34 count value is loaded to Y, the count value Y in step S35, and stored in the measurement position Y direction address location memory M27 for storing the reference mark as a measurement position in the Y direction of the reference mark 1c, after step S36 to be described later processing is carried out.
[0059]
　Incidentally, when the process proceeds from step S25 described above to step S129, and overwrites the count value X memory M18 for storing adds 1 to the count value X at step S129, from the memory M20 in the lateral direction of the camera 124 in step S130 reads the number of pixels, reads the number of pixels the horizontal direction of the reference mark 1c from the memory M25 in step S131.
[0060]
　Subsequently, the count value X is in the step S132 - If (the number of pixels in the horizontal direction of the camera horizontal direction number of pixels of the reference mark) or less (NO), the flow returns to step S21, the count value X is (camera left-right direction number of pixels - When larger than the reference number of pixels lateral direction mark) (YES), adds 1 to the count value Y in step S133 overwrites the count value Y for storing the memory M17.
[0061]
　Subsequently, it reads the number of pixels vertical direction of the reference mark 1c from the memory M26 from the memory M21 the number of pixels vertical direction of the camera 124 reads, in step S135 in step S134. Subsequently, the count value Y in step S136 - if (number vertical direction of the pixels of the camera vertical direction number of pixels of the reference mark) or less (NO), the flow returns to step S20, the count value Y is (camera vertical direction number of pixels - When larger than the number of pixels the vertical direction) of the reference mark (YES), displays an error message on the display unit 19 proceeds to step S138 shown in FIG. 10B.
[0062]
　That is, in step S19 ~ step S35 and step S129 ~ step S136, as a third step, the image data obtained in the second step described above, obtains a reference mark 1c using pattern matching, stores the position to. In addition, if the reference mark 1c can not be detected to display the error.
[0063]
　After the migration from step S35 to step S36, the character / number search from a reference mark measured positions in the X direction of the reference mark 1c than the X-direction address position of the measuring position memory M27 for storing the reference mark read, in step S37 in step S36 It reads the distance in the X direction from a reference mark 1c than X direction address location distance storage memory M28 to the start position to the character / number search start position.
[0064]
　Then, by adding the distance in the X direction from the reference mark 1c until a character / number search start position to the measuring position in the X direction of the reference mark 1c in step S38, the position of the X-direction of the search start position of the entire character / number thereby calculated and stored in the character / number entire search start position X-direction address position of the storage memory M29.
[0065]
　Then, read the lateral direction of the length in the X-direction address position from the character / number entire search range of characters / numbers overall search size storage memory M30 in step S39 (see A of FIG. 11), step S40 character with in adding the left-right direction of the length of the search range of the entire character / number in the X-direction position of the search start position of the entire character / number, calculates the X position of the search end position of the entire character / number / number stored in the search end position X direction address location memory M31 for storing the total.
[0066]

[0068]
　Then, read the vertical direction of the length of the character / number entire search size Y direction address position from the character / number entire search range storing memory M30 in step S44, the start of the search entire character / number in step S45 adding the vertical direction of the length of the search range of the entire character / number in the Y-direction position of the position, the entire character / number with calculates the position in the Y direction of the search end position of the entire character / number search end position storage stored in the Y-direction address position of use the memory M31.
[0069]
　That is, in step S36 ~ step S45, as a fourth step, the position of the reference mark 1c obtained in the third step described above, obtaining the expected range and a character / number column 1b.
[0070]
　Subsequently to step S45, overwriting the Y direction position of the search start position of the entire character / number in the count value Y for storing the memory M17 in step S46, the entire character / number in the count value X memory M18 for storing in step S47 overwrites the search start X-direction position of the position of overwrites 1 the count value N memory M22 in step S48, the overwriting 1 for storing the count value M memory M23 in step S49.
[0071]
　Subsequently, (X, Y) of the imaging data storing memory M19 in step S50 the address from the address position (X, Y) read the pixel data of the threshold for the memory M32 binarization in step S51 It reads.
[0072]
　Subsequently, if the address (X, Y) above threshold for pixel data are binarized in step S52 (YES), in step S53 binarized image data storage memory M33 (M , to override the "1" to the address position of N). On the other hand, the address (X, Y) is less than the threshold value for the pixel data of the binarization (NO), the processing proceeds to step S137 binarized image data storage memory M33 (M, in the address location N) to override the "0", the process proceeds to step S54 to be described later.
[0073]
　In step S54, 1 is added to the count value M overwrites the count value M storage memory M23, subsequently overwrites the count value X memory M18 for storing adds 1 to the count value X in step S55, It reads the position in the X direction of the search end position of the entire character / number from the memory M31 in step S56.
[0074]
　Then, if the count value X is less than or equal to the position in the X direction of the search end position of the entire character / number in the step S57 (NO), returns to step S48, the count value X is the search ending position of the entire character / number X When larger than the direction of the position (YES), adds 1 to the count value N in step S58 overwrites the count value N memory M22.
[0075]
　Subsequently to step S58, the overwrite count value Y memory M17 for storing adds 1 to the count value Y in step S59, the position from the memory M31 the search end position of the entire character / number in the Y direction in step S60 It reads. Then, if the count value Y is less than or equal to the position in the Y direction of the search end position of the entire character / number in the step S61 (NO), returns to step S47, the count value Y is the search ending position of the entire character / number Y When larger than the direction of the position (YES), it performs the subsequent processing step S62.
[0076]
　That is, in step S46 ~ step S61 and step S137, as a fifth step, binarizing the image data of the range that is expected to be a character / number string 1b obtained in the fourth step described above.
[0077]
　At step S62, it is overwritten with 1 in the count value L storage memory M34, followed by the L-th from L th address location of the P-th K-th row of the character / number string storage memory M14 in step S63 the character / Nde read the numbers stored in the memory M35, step S64 reference characters / numbers from a memory M36 for storing corresponding to the L-th character / number reads the binary data of characters / numbers, reference characters / numbers of the pixel data stored in It is stored in the use memory M37.
[0078]
　That is, in step S62 ~ step S64, as a sixth step, from the character / number string 1b stored in the first step described above, obtains a character / number of the first (L = 1), the corresponding binarized stored as the reference image pixel data.
[0079]
　Subsequently to Step S64, is overwritten with 1 in the count value Y for storing the memory M17 in step S65, the L-th from L th address location of the search start position memory M38 for storing each character / number in step S66 the character / It reads the search start position in the X direction number overwrites the search start position in the X direction L th character / number in the count value X memory M18 for storing in step S67.
[0080]
　Subsequently, overwriting the 0 to NG pixel count memory M39 for storing each character / number in step S68, is overwritten with 1 the count value N memory M22 in step S69, the count value M memory M23 for storing in step S70 It is overwritten with 1 in.
[0081]
　Subsequently, in the image data memory M33 is binarized at step S71 (X + M-1, Y + N-1) reads the pixel data of the address location of the memory pixel data stored in the reference characters / numbers in step S72 M37 the (M, N) reads the pixel data of the address location.
[0082]
　Subsequently, in step S73 binarized pixel data at the address position of (X + M-1, Y + N-1) is (M, N) to be equal to the reference characters / numbers of the pixel data of the address position (NO ), by overwriting the NG pixel count memory M39 for storing adds 1 to the NG pixel count for each character / number in step S74, the process proceeds to step S75. On the other hand, step binarized pixel data (M, N) if they match the standard character / number of the pixel data of the address location of the (YES), described later, of the address location (X + M-1, Y + N-1) the process proceeds to S75.
[0083]
　At step S75, the 1 is added to the count value M, overwrites the count value M storage memory M23, followed by the left-right direction of the number of pixels of the reference characters / numbers from the memory M40 in step S76 (e.g., 11 Pa reference) reads the.
[0084]
　Then, if the count value M is reference characters / numbers lateral direction of less than or equal to the number of pixels in the step S77 (NO), the process returns to step S71, becomes the count value M is larger than the number of pixels the horizontal direction of the reference characters / numbers When (YES), adds 1 to the count value N in step S78 overwrites the count value N memory M22.
[0085]
　Subsequently to Step S78, the vertical direction of the number of pixels of the reference characters / numbers from the memory M41 in step S79 (e.g., Pb reference shown in FIG. 11) reads, vertical direction of the count value N reference characters / numbers in Step S80 if the number of pixels less (NO), the flow returns to step S70, the When the count value N is larger than the number of pixels vertical direction of the reference characters / numbers (YES), NG from the memory M39 for each character / number in step S81 It reads the number of pixels.
[0086]
　Subsequently, reads reads the number of pixels the horizontal direction of the reference characters / numbers from the memory M40, the number of pixels vertical direction of the reference characters / numbers from the memory M41 in step S83 in step S82.
[0087]
　Following step S83 divides the number of NG pixels each letter / number "(reference number of pixels horizontal direction of the character / number) × (number of pixels vertical direction of the reference character / number)" in step S84, the thereby calculating the similarity rate similarity rate of the storage memory M42 (X, Y) stored in the address location, overwriting the count value X memory M18 for storing adds 1 to the count value X in step S85, the step S86 in the search range of each character / number from the memory M43 (A1 ~ aN shown in FIG. 11 L reads the number of pixels left and right directions of the reference).
[0088]
　Then, read the number of pixels the horizontal direction of the reference characters / numbers from the memory M40 in step S87, the count value X is (the number of pixels horizontal direction of the search range for each character / number in step S88 - the left and right reference characters / numbers if the direction number of pixels + 1) or less (NO), the flow returns to step S69, the count value X is (the number of pixels horizontal direction of the search range for each character / number - reference characters / numbers number of horizontal direction pixels +1) When it larger (YES), adds 1 to the count value Y in step S89 overwrites the count value Y for storing the memory M17.
[0089]
　Subsequently, it reads the number of pixels vertical direction of reading the number of pixels vertical direction of the search range for each character / number from the memory M44, the reference characters / numbers from the memory M41 in step S91 in step S90.
[0090]
　Subsequently, the count value Y in step S92 - If (number vertical direction of the pixels of the search range for each character / number reference characters / numbers number vertical direction of pixels +1) or less (NO), the flow returns to step S66, the count value Y is - When larger than (the number of pixels vertical direction of the search range for each character / number reference characters / numbers in the circumferential direction number of pixels +1) (YES), the process proceeds to step S93.
[0091]
　That is, in step S65 ~ step S92, as a seventh step, by using a pattern matching, a character / number of the first in the fifth step in the binarized image data described above (L = 1) obtaining a similarity rate for the expected at each position within (A1) is, the reference images stored in the sixth step described above with (different pixel ratio).
　That is, as shown in FIG. 11, the first letter / number expected in the search range A1 that there is a region corresponding to the reference image (the number of horizontal direction pixels Pa, in the circumferential direction number of pixels of the Pb region ) in the X direction, it matches the reference image while shifting in the Y direction, obtaining the similarity rate of the reference image (different pixel ratio) for each position.
[0092]
　Step S93 In reads search start position in the X direction of the L-th character / number from the search start position L th address location memory M38 for storing each character / number, followed by the similarity rate storage memory M42 in Step S94 (L-th character / number X-direction of the search start position of, 1) (search start position in the X direction L th character / number 1) from the address position of the minimum value of the similarity rate with loads the similarity rate of the position (X-direction of the search start position of the L-th character / number, 1) in the storage memory M45 (search start position in the X direction L th character / number, 1) the position of the similarity rate and location to overwrite.
[0093]
　Subsequently, overwriting 1 in the count value Y for storing the memory M17 in step S95, X-direction of the L-th character / number from the search start position L th address location memory M38 for storing each character / number in step S96 It reads the search start position, overwrites the search start position in the X direction L th character / number in the count value X memory M18 for storing in step S97.
[0094]
　Subsequently, it reads reads the minimum value of the similarity rate from the memory M45, the similarity rate storage memory M42 in step S99 (X, Y) (X, Y) from the address position of the similarity rate of the position in step S98.
[0095]
　Subsequently, the minimum value of the similarity rate in step S100 is the (X, Y) is greater than the similarity rate of the position (YES), in step S101 (X, Y) position of the similarity rate and the position of the address (X, Y) overwrites the minimum value storage memory M45 similar rate, the process proceeds to step S102. On the other hand, the minimum value of the similarity rate is (X, Y) not more than the similarity rate of the position (NO), there moves to step S102 to be described later.
[0096]
　In step S102, 1 is added to the count value X overwrites the count value X storage memory M18, followed by reading the number of pixels horizontal direction of the search range for each character / number from the memory M43 in step S103, step It reads the number of pixels the horizontal direction of the reference characters / numbers from the memory M40 in S104.
[0097]
　Subsequently, the count value X is in the step S105 - If (the number of pixels horizontal direction of the search range for each character / number reference characters / numbers number of horizontal direction pixels +1) or less (NO), the flow returns to step S98, the count value X is - When (the number of pixels horizontal direction of the search range for each character / number reference characters / numbers in the left-right direction of the pixel count plus) than larger (YES), 1 is added to the count value Y in step S106 It overwrites the count value Y memory M17 for storing Te.
[0098]
　Subsequently to Step S106, it reads reads the number of pixels vertical direction of the search range for each character / number from the memory M44, the number of pixels vertical direction of the reference characters / numbers from the memory M41 in step S108 in step S107.
[0099]
　Subsequently, the count value Y in step S109 - if (number vertical direction of the pixels of the search range for each character / number reference characters / numbers number vertical direction of pixels +1) or less (NO), the flow returns to step S96, count value Y is - When larger than (the number of pixels vertical direction of the search range for each character / number reference characters / numbers in the circumferential direction number of pixels +1) (YES), the process proceeds to step S110.
[0100]
　That is, in step S93 ~ step S109, as an eighth step, at each position of the search range within the range A1 which is expected to be character / number of the first (L = 1) obtained in the seventh step described above obtaining the minimum value and its position of similarity rate (different pixel ratio) of the reference image.
　That is, in the range A1, which is expected to have the first character / number, similarity rate of the reference image position (different pixel ratio) is the smallest search area is obtained as the position of the first character / number.
[0101]
　Step S110 In reading the minimum value of the similarity rate from the memory M45, subsequently reads the tolerance from the memory M46 becomes a criterion of similarity of each character / number in step S111, the minimum value is the character of the similarity rate in step S112 if less than the allowable value of the similarity rate of the / number (YES), it performs the subsequent processing step S113. On the other hand, the minimum value of the similarity rate is greater than the allowable value of the similarity rate of each character / number (NO), and displays an error message on the display device 19 proceeds to step S138 shown in FIG. 10B.
[0102]
　Here, the allowable value storage memory M46 of the similarity rate of each character / number in the present embodiment, the common value is stored for Kogire 1a of every line as an allowable value of the similarity rate of each character / number and those are.
[0103]
　That is, in step S110 ~ step S112 described above, as a ninth step, comparing the minimum similarity rate and the character / number common tolerance determined in the eighth step described above. Minimum when the similarity rate is greater than the character / number common tolerance, an error display.
[0104]
　If step S113 the count value L 1 (YES), reads the address X from the minimum X-direction address locations for storing memory M45 of the similarity rate in step S114. On the other hand, if the count value L is other than 1 (NO), the process proceeds to step S139 to be described later.
[0105]
　Following step S114, the step S115 in the first character / number reads the reference position the reference position in the X direction from the X-direction address position of the storage memory M47, and subtracting the reference position in the X direction from the address X at step S116 , store in the X-direction address position difference storage memory M48 position while calculating the difference in position in the X direction, the absolute of the difference between the position as well as calculating the absolute value of the difference in the position of the X-direction in step S117 stored in the X-direction address location for storing the value of the memory M49.
[0106]
　Subsequently to step S117, the read count value K from the memory M12 in step S118, X and K th Kogire 1a than the allowable value address position in the X direction of the K-th row of a memory M50 for storing the position in step S119 It reads the allowable value as the direction of the criteria.
[0107]
　Here, the allowable value memory M50 for storing the position in the present embodiment, the position of the X direction Kogire 1a for each row (count value K) taking into account the elongation of the pattern of the paper trailing edge of the large-size printed matter 1 shall permissible values ​​are stored. Specifically, the added side of the tolerance of position in the X direction of the character / number with respect to the reference mark 1c of Kogire 1a, the X-direction of a character / number with respect to the reference mark 1c of Kogire 1a of the paper trailing edge shall tolerance position is large.
[0108]
　Then, if the absolute of the difference in the position of the X direction value is less than the allowable value in the X direction of the K-th row Kogire 1a in step S120 (NO), the minimum value of the memory M45 for storing the similarity rate in step S121 It reads the address Y from the Y-direction address position. On the other hand, the absolute value of the difference in the position of the X-direction is greater than the allowable value in the X direction of the K-th row of Kogire 1a (YES), displays an error message on the display unit 19 proceeds to step S138 shown in FIG. 10B .
[0109]

[0111]
　Subsequently, it reads the allowable value as a Y direction criterion position for storing the allowable value memory M50 of the K-th row in the Y direction address locations than K-th Kogire 1a at step S126.
[0112]
　Here, the allowable value memory M50 for storing the position in the present embodiment, the position in the Y direction Kogire 1a for each row (count value K) taking into account the elongation of the pattern of the paper trailing edge of the large-size printed matter 1 shall permissible values ​​are stored. Specifically, the added side of the tolerance of position in the Y direction of the character / number with respect to the reference mark 1c of Kogire 1a, the character / number with respect to the reference mark 1c of Kogire 1a of the paper trailing edge of the Y-direction shall tolerance position is large.
[0113]
　Then, if the absolute of the difference between the position in the Y direction value is less than the allowable value of the Y direction K th Kogire 1a in step S127 (NO), the process proceeds to step S128. On the other hand, the absolute value of the difference between the position in the Y direction is greater than the allowable value of the Y direction K th Kogire 1a (YES), displays an error message on the display unit 19 proceeds to step S138 shown in FIG. 10B .
[0114]
　That is, in step S113 ~ step S127, step S138, a tenth step, the similarity rate is lowest position relative to the first character / number of the reference image obtained in the ninth step described above, the preset reference mark the difference between the reference position with respect to the position (hereinafter simply referred to as the difference between the reference position) sought, the allowable value of the position is the difference with criteria set for each number of lines Kogire 1a the reference position calculated and Compare. The difference between the reference position is greater than the allowable value of the position error display.
[0115]
　In step S128, overwrite the 2 count value L storage memory M34, the flow returns to step S63.
[0116]
　Further, when the process proceeds from step S113 to step S139, and overwrites the count value L storage memory M34 by adding 1 to the count value L in step S139, a character / number from the memory M51 the Kogire 1a at step S140 It reads the number of digits.
[0117]
　Then, if the count value L is equal to or less than the number of digits of each Kogire 1a characters / numbers in step S141 (NO), the process returns to step S63, the count value L than the number of digits of each Kogire 1a characters / numbers When larger (YES), adds 1 to the count value K in step S142 overwrites the count value K storage memory M12.
[0118]
　Step S143 In reading the number of lines Kogire 1a in large format prints from the memory M52, if the count value K is less than or equal to the number of rows Kogire 1a in large format prints at step S144 (NO), the process returns to step S3, count When the value K is larger than the number of rows Kogire 1a in large-format prints (YES), 1 is added to the number of printed sheets count value P in step S145, and overwrites the number of printed sheets count value P for storing the memory M11, step Back to S2.
[0119]
　That is, in step S128, steps S139-step S145, an eleventh step, the same processing as the sixth to ninth step, the second (L = 2) from the last character / number (L = N L ) of repeating the character / number, a twelfth step, the same processing as steps of the first to eleventh, last from Kogire 1a of the second row (K = 2) (K = N K line of) small Repeat for cutting 1a, as a 13 step, the same processing as the first to twelfth step, the large-format prints of the second sheet (P = 2) last (P = N P for large format print) (i.e. printing until the end) is repeated.

　That is, in the present embodiment, the allowable value for determining the appropriateness of printed characters / numbers in each Kogire 1a (the criterion), each row in view of the elongation of the pattern of the paper trailing edge of the large-format printed matter 1 ( and to set for each count value K). Further, while using a common tolerance on all Kogire 1a for inspection of geometrical similarity of each character / number, inspection of the position of the character / number string 1b with respect to the reference mark 1c is set for each row and so it inspected using different tolerance and can be set separately tolerance only test necessary items. The reference mark 1c and inspection of positional relationship between the character / number string 1b is carried out by only the character / number at the nearest position from the reference mark 1c, all similarity rate of the reference image of the character / number characters / numbers It was to perform for.
[0121]
　According to the character / number check unit of securities according to the present embodiment constructed in the paper trailing edge elongation occurs in the pattern of large-format prints 1, character relative to the reference mark 1c compared to addition side / even if the position of the number is slightly deviated, if it is within geometrical similarity rate allowable value of the character / number can be judged to be correctly printed, the shape similarity of each character / number while maintaining the accuracy of the rate of inspection, incorrectly it is possible to suppress receiving the error, thereby improving the quality of testing.
[0122]
　In the present embodiment described above, an example to be set, the tolerance of the position of Kogire 1a for each row an example of an inspection of Kogire 1a only one column (the count value K), picture the elongation for may vary depending on the position in the column direction, the allowable value of the position of Kogire 1a is preferred to set for each row and each column. However, the present invention is not intended to be limited to the embodiments described above, for example, permit at least the tolerance of the position of one Kogire 1a other Kogire 1a positioned according to the elongation of the pattern of the paper ass may be a value different way, it is needless to say that various modifications can be made without departing from the scope of the present invention.
Industrial Applicability
