[0025]
　Blade member 13 is formed in a disk shape. Blade member 13, the disc plane is disposed so as to be perpendicular to the longitudinal direction (arrangement direction of the pair of clamps 11, 12) of the optical fiber 100. Blade member 13, to the pair optical fiber 100 that is grasping clamp 11, 12 and to the, to be movable between clamping 11,12 a pair in a direction perpendicular to the longitudinal direction of the optical fiber 100 there.
　Blade member 13, by the way of the movement path the outer peripheral edge 19 of the blade member 13 in (during movement) (cutting edge) contacts the gripping surface of the optical fiber 100 to the clamp 11, 12 to 1, the light the surface of the fiber 100 to scratching.
[0026]
　Blade member 13 is rotatable about the axis of the blade member 13 on the blade base 20.

Thus, the outer peripheral edge 19 position of the blade member 13 in contact with the optical fiber 100 can be appropriately held.
[0027]
　In the optical fiber cutting apparatus 2 of the present embodiment, the longitudinal and the outer peripheral edge of the optical fiber 100 and the blade member 13 in the (upward direction in FIG. 2) the height direction perpendicular to the moving direction of the blade member 13 of the optical fiber 100 the relative positions of the parts 19 can be changed. This makes it possible to vary the time of scratching the surface of the optical fiber 100 in the blade member 13, the pressure for pressing the outer peripheral edge 19 of the blade member 13 on the surface of the optical fiber 100 (contact pressure).
[0028]
　Center in the optical fiber cutting device 2 illustrated in FIG. 2, the blade member 13 relative to blade base 20 disposed movably in the moving direction of the blade member 13 described above on the base 17, the axis of the blade member 13 It is rotatably provided. Blade base 20 is a member which slides on the base 17. The base 17 is provided with a spring (not shown), blade base 20 is fired by opening was compression spring, that the blade member 13 contacts the optical fiber 100 during movement of the blade base 20 Become.
　In the optical fiber cutting device 2 illustrated in FIG. 2, is adjustable position of the blade member 13 in the height direction (height position), the optical fiber 100 which is gripped by a pair of clamps 11 and 12 high is position is fixed. It will be described in detail below mechanism for adjusting the height position of the blade member 13.
[0029]
　In the optical fiber cutting device 2 illustrated in FIG. 2, blade base 20 includes a base portion 21, a swing unit 22 is swingably connected to the base portion 21, a. Shaft connecting the base portion 21 and the swinging portion 22 (connecting shaft) is parallel to the longitudinal direction of the optical fiber 100. Swinging portion 22 extends in a direction away from the connecting shaft. Blade member 13 is provided in the intermediate portion of the extending direction of the oscillating portion 22. The distal end of the extending direction of the oscillating portion 22, adjusting screw 23 to adjust the height position of the distal end portion of the oscillating portion 22 with respect to the base portion 21 is attached.

　In the present embodiment, adjustment of the height position of the rotation and the blade member 13 of the blade member 13 is adjusted manually by the operator handling the optical fiber cutting device 2.
[0030]
　Figure 3A ~ FIG 3D is a view illustrating a step of scratching the surface of the optical fiber 100 by the blade member 13. FIGS. 4A ~ 4D are when near the relative position of the optical fiber 100 and the blade member 13 than in FIG 3A ~ Figure 3D, for illustrating a step of scratching the surface of the optical fiber 100 by the blade member 13 it is a diagram of.
　In the optical fiber cutting apparatus 2 comprising a clamp 11, 12 and the blade member 13 of the pair described above, when the surface of the optical fiber 100 to the scratching (give an initial flaw to the surface of the optical fiber 100), FIG. 3B ~ Figure 3D and as shown in FIG. 4B ~ Figure 4D, by moving in a direction perpendicular to the longitudinal direction of the optical fiber 100 gripped blade member 13 by a pair of clamps 11 and 12, the outer peripheral edge of the blade member 13 pressing the parts 19 on the surface of the optical fiber 100.
　In this case, the optical fiber 100 located between a pair of clamps 11 and 12, as shown in FIGS. 3A and 4A, deflected by the pressing of the blade member 13. Thus, among the circumferential direction of the predetermined length of the outer peripheral edge 19 of the blade member 13 comes into contact with the surface of the optical fiber 100. In the following description, the predetermined length is referred to as "contact length" of the blade member 13 with respect to the optical fiber 100. Contact length of the blade member 13 with respect to the optical fiber 100 is indicated by reference numeral CL1, CL2 in FIG. 3D and FIG. 4D.
[0031]
　Contact length of the blade member 13 is changed in accordance with the relative positions of the optical fiber 100 and the blade member 13 in the height direction. For example, as shown in FIGS. 3A ~ Figure 3D, when the upper end of the blade member 13 in the height direction is located relatively downward with respect to the optical fiber 100 has a small bending of the optical fiber 100 (the contact pressure is low) , short contact length CL1 of the blade member 13. On the other hand, as shown in FIG. 4A ~ Figure 4D, when the upper end of the blade member 13 is positioned above as compared with the case of FIG. 3A ~ Figure 3D in the height direction, bending of the optical fiber 100 is large (contact pressure is high), the contact length CL2 of the blade member 13 becomes longer. If the cutting performance of the outer peripheral edge 19 of the blade member 13 are the same, a large degree of better contact length of the blade member 13 is long to scratching the surface of the optical fiber 100.
[0032]
　Pressing member 14 shown in FIG. 2, after Kakizu the surface of the optical fiber 100 by the blade member 13, by bending down the scratching of the optical fiber 100, to cut the optical fiber 100.
[0033]
　In the optical fiber cutting apparatus 2 described above, the blade member 13 is rotatable. Therefore, the outer peripheral edge 19 (the circumferential direction of the portion of the outer peripheral edge portion 19) of a predetermined (identical) of the blade member 13, and / or to the scratching of repeating optical fiber 100 every time the contact pressure of a predetermined (identical) it is, if a predetermined outer peripheral edge 19 is worn cutting performance for by (time wear of the cutting edge of the blade member 13, including the deterioration of aging defect, etc.) to cut the optical fiber 100 decreases, the blade member 13 rotates the by changing the position of the outer peripheral edge 19 of the blade member 13 in contact with the optical fiber 100. Specifically, another outer peripheral edge 19 adjacent to a predetermined outer peripheral edge portion 19 so as to contact the optical fiber 100 during scratching, to rotate the blade member 13. Thus, the aforementioned cutting performance is restored.
[0034]
　In the optical fiber cutting apparatus 2 described above, the relative position between the optical fiber 100 and the blade member 13 is changeable in the height direction. Therefore, the outer peripheral edge 19 of a predetermined (identical) of the blade member 13, and / or, by scratches pressure repeating optical fiber 100 every time the contact pressure of a predetermined (identical), a predetermined outer peripheral edge 19 is worn If the cutting performance for cutting the optical fiber 100 decreases Te, as the contact pressure is high (so that the contact length increases), the relative position between the optical fiber 100 and the blade member 13 in the height direction to change the. Thus, the aforementioned cutting performance is restored.
　In the above description, whether the cutting performance is lowered, for example, the operator determines to check the status of the end face of the optical fiber 100 after cutting.
[0035]
　As shown in FIGS. 1 and 2, the acquisition unit 10 acquires the position information of the outer peripheral edge 19 of the blade member 13 in contact with the optical fiber 100.
　Acquisition unit 10 of the present embodiment, as the position information of the outer peripheral edge 19 of the blade member 13 with respect to the optical fiber 100, including the outer edge position measuring sensor 15 which measures the rotational angle of the blade member 13 (the rotational position). In other words, outer edge position measuring sensor 15 measures the position of the outer peripheral edge 19 of the blade member 13 in contact with the optical fiber 100. In the present embodiment, outer edge position measuring sensor 15 is provided in an optical fiber cutting device 2.
　Outer edge position measuring sensor 15 may measure the rotation angle of the blade member 13 continuously, but the rotation angle may be discretely determined. The number of rotation angles of the measured blade member 13 (the position of the outer peripheral edge 19) may be set as appropriate in accordance with the diameter of the blade member 13, but in this embodiment a sixteen. That is, in this embodiment, arranged in the circumferential direction of the blade member 13, and the number of 16 locations in the position of the outer peripheral edge 19 of possible blade member 13 be used for the cutting of the optical fiber 100.
[0036]
　Meanwhile, the blade table 20, blade base 20 is fired by opening was compression spring, the blade member 13 after contact with the optical fiber 100, and stops shocked at the end of the moving range during movement It will be. Therefore, if when the sensor for measuring the rotational position of the blade member 13 (and the height position) is provided on the blade base 20, wiring and the sensor, it is difficult to ensure the durability of the wire. Therefore, a sensor for measuring the rotational position of the blade member 13 does not move together with the blade member 13 and blade base 20, it is desirable to provide on the side of the base 17.
　Additionally, if (reflector for reflecting light, or a through hole for transmitting light) marker plurality (16) at equal intervals in the outer edge portion of the blade member 13 in the circumferential direction is arranged, the outer edge position measuring sensor 15 using an optical sensor by detecting one marker, when measuring the rotational position of the blade member 13, due to the influence of swarf and coating debris optical fiber has on the detection light of the optical sensor, accurate position measurement there can not be afraid. Also, when measuring the rotational position of the blade member 13 by using an optical sensor, by the disturbance light enters from the outside of the device, there is a possibility which can not be positioned accurately measured. Therefore, the outer edge position measurement sensor 15 of the present embodiment utilizes a magnetic sensor for detecting the magnetism measuring the rotational position of the blade member 13.
[0037]
　FIGS. 5A ~ 5C are explanatory views of a magnetic sensor. 5A and 5B are diagrams showing the relationship between the rotational position of the magnetic sensor and the magnet (rotation angle). Figure 5C is an explanatory view of an output characteristic of the magnetic sensor.
[0038]
　Magnet is configured in a disc shape, and is magnetized in the diameter direction. Here, as shown in FIGS. 5A and 5B, one side of a predetermined diameter direction becomes N pole, so that opposite side is the S pole, disc-shaped magnets are magnetized in the diameter direction. The magnetic sensor is a so-called magnetic angle sensor. The magnetic sensor detects the direction of the magnetic lines of force, a sensor which outputs a signal corresponding to the direction of the magnetic field lines.
[0039]
　As shown in FIGS. 5A and 5B, it is applied markings on the magnetic sensor package. Here, as shown in FIG. 5A, if the N pole of the magnet is facing the marking side of the magnetic sensor, and the rotational position of the magnetic sensor and the magnet 0 ° (reference angle). Further, as shown in Figure 5B, the angle which the magnet is rotated from the reference angle with respect to the magnetic sensor counterclockwise and "rotational position of the magnetic sensor and the magnet". For example, "the rotational position of the magnetic sensor and the magnet" shown in FIG. 5B is a "90 °".
[0040]
　As shown in FIG. 5C, the magnetic sensor outputs a signal (output voltage) corresponding to the rotational position of the magnetic sensor and the magnet. Here, in the range rotational position of 360 degrees from 0 degrees between the magnetic sensor and the magnet, the output voltage of the magnetic sensor is changed linearly. However, the output voltage of the magnetic sensor may be any correlation with the rotational position of the magnetic sensor and the magnet, not necessarily change linearly.
[0041]
　Figure 6A is a perspective view for explaining a rotary unit 50 which is provided on the side of the blade member 13, the sensor-side unit 60 provided on the side of the outer edge position measuring sensor 15. 6B is a cross-sectional view for explaining a rotary unit 50 which is provided on the side of the blade member 13, the sensor-side unit 60 provided on the side of the outer edge position measuring sensor 15. Figure 7 is an exploded explanatory view of the rotation unit 50.
[0042]
　Rotation unit 50 is a mechanism for rotatably holding the blade member 13 and the magnet 51 relative to the blade base 20. Here, the rotation unit 50 is provided in the swinging portion 22. Rotation unit 50, in addition to the blade member 13 and the magnet 51 has a pressing member 52, a rotary shaft 53, and a ratchet mechanism 54. Pressing member 52 is an example of a fixing part for fixing the disk-shaped blade member 13. Here, the pressing member 52 is a fixed part for fixing the blade member 13 with the ratchet disc of the ratchet mechanism 54. Pressing member 52 has a flange portion 521, and a projecting portion 522. Flange portion 521 is a portion flange-shaped for holding down the sides of the blade member 13. Note that the side surface of the flange portion 521 are shown the direction of magnetic force lines of the magnet 51. Protrusion 522 is a portion that protrudes from the flange portion 521 on the sensor side. Magnet 51 is provided on the sensor-side surface of the projecting portion 522. Incidentally, the magnet 51 is configured in a disc shape, and is magnetized in the diameter direction. The ratchet mechanism 54 is a mechanism for holding and switching between rotatable state blade member 13 and the non-state rotation. The ratchet mechanism 54 includes a ratchet disc 541 and a ratchet pawl 542. The outer periphery of the ratchet disc 541, the ratchet wheel is formed. By the ratchet pawl 542 is engaged with the ratchet disc 541, while allowing rotation of the ratchet disc 541, it is possible to fix the ratchet disc 541 while maintaining a predetermined rotational position.
[0043]
　Instead of providing the magnets 51 in the pressing member 52, blade member 13 may be formed by magnets. In this case, since the blade member 13 that has been magnetized to generate magnetic lines of force, the outer edge position measuring sensor 15 composed of a magnetic sensor senses the magnetic field lines generated by the blade member 13, the rotational position of the blade member 13 it is possible to output the response signal. In this case, it is possible to simplify the structure of the pressing member 52.
[0044]
　The blade member 13, the fitting hole 13A is formed. The ratchet disc 541 and the convex portion 541A is formed, the convex portion 541A is fitted into the fitting hole 13A of the blade member 13. Further, the pressing member 52 and the convex portion 521A (see FIG. 6B) is formed, a convex portion 521A is also fitted into the fitting hole 13A of the blade member 13. Thus, the blade member 13 and the presser member 52 relative to the ratchet disc 541 is fixed, a magnet 51 provided on the pressing member 52 is rotatably held with the blade member 13.
[0045]
　Sensor side unit 60 is a mechanism for rotatably holding the outer edge position measuring sensor 15 (magnetic sensor). Sensor side unit 60 includes a pivot member 61, and a sensor for the rotary shaft 62. Pivot member 61 while retaining the outer edge position measuring sensor 15 is a magnetic sensor, a member being rotatable sensor rotation shaft 62 as an axis. In the normal state, as shown in FIGS. 6A and 6B, the rotational position of the pivot member 61 is made of an outer edge position measuring sensor 15 to the opposable position to the magnet 51. Rotation of the pivot member 61 from the normal state, as shown in FIG. 7, the outer edge position measurement sensor 15 is in a position not facing the magnet 51. For example during replacement of the blade member 13, to rotate the pivot member 61, by retracting the outer edge position measurement sensor 15, it becomes possible to detach the pressing member 52 provided with the magnet 51.
[0046]
　Outer edge position measuring sensor 15 is constituted by a magnetic sensor, it detects the magnetic lines of force magnets 51 is generated, and outputs a signal corresponding to the rotational position of the magnet 51. Therefore, even if between the outer edge position measuring sensor 15 and the magnet 51 as it enters the cuttings and coating debris optical fiber 100, the outer edge position measurement sensor 15, the influence of swarf and coating debris optical fiber 100 without being, can output a signal corresponding to the rotational position of the magnet 51. Moreover, even if from the outside as it enters the ambient light, the outer edge position measurement sensor 15, without being affected by ambient light, it outputs a signal corresponding to the rotational position of the magnet 51. Therefore, outer edge position measurement sensor 15, the rotational position of the blade member 13 (rotation position) can be measured accurately. Rotation angle (measured value) of the outer edge position measuring sensor 15 blade member 13 that has been measured, the output from the outer edge position measuring sensor 15, for example an electrical signal.
[0047]
　Further, the acquisition unit 10 of the present embodiment acquires the relative positional information between the outer peripheral edge 19 of the optical fiber 100 and the blade member 13 in the height direction. Specifically, the acquiring unit 10 of the present embodiment, as the relative position information, contact length measuring sensor for measuring the position of the outer peripheral edge 19 of the blade member 13 in the height direction (height position of the blade member 13) including (position measuring sensor) 16. In the present embodiment, the contact length measuring sensor 16 is provided in an optical fiber cutting device 2.
　Contact length measuring sensor 16 may measure the height position of the blade member 13 is continuously but discretely measure the height position in the present embodiment. The number of the height position of the measured blade member 13 may be any, but in this embodiment, "low", "medium", and three and the "high". That is, in this embodiment, the position of the same peripheral edge portion 19, and three the number of height positions of possible blade member 13 be used for the cutting of the optical fiber 100.
　Therefore, in the present embodiment, the total number of positions of the blade member 13 that can be used to cut the optical fiber 100, the number 16 places the position of the outer peripheral edge portion 19 in the circumferential direction of the blade member 13, blade member 13 the 48 points obtained by multiplying the number three height positions.

　Contact length measuring sensor 16 is, for example, as shown in FIG. 2, the are arranged opposable to the head of the adjusting screw 23 (FIG. 2, to indicate the magnet 24 of the head of the adjusting screw 23, the contact length measuring shown in dotted lines the sensor 16 in the transparent). Adjustment screw 23 is a rotating member for adjusting the height position of the distal end portion of the swinging portion 22. Rotation of the adjusting screw 23 is adjusted the amount of protrusion of the lower end of the adjusting screw 23 from the lower surface of the swinging portion 22, by which the height position of the distal end portion of the swinging portion 22 is adjusted, as a result, the blade so that the height position of the member 13 is adjusted. The head of the adjusting screw 23, the magnet 24 is provided. Here, as is the head of the adjusting screw 23 is formed in a disc shape, the magnetic field lines is applied to the disc-shaped head with a diameter direction (direction perpendicular to the axis of rotation of the adjustment screw 23), adjusting the head of the screw 23 are magnetized. However, instead of magnetizing the head of the adjustment screw 23, a fixed part fixed to the adjustment screw 23 (part which rotates together with the adjustment screw 23), the magnetic field lines is applied in a direction perpendicular to the axis of rotation of the adjustment screw 23 it may be.
