[0012]

　Thus, the amount of the bill 1 which is housed tape 2a, together 2b on the circumference of the drum 10 is increased, the diameter of the drum 10 is increased, the diameter of the reel 31, 32 is reduced.

[0013]

　When the amount of storage of the bill 1 is increased, a large amount of tape 2a on the circumference of the drum 10, 2b and tape 2a, bill 1 is sandwiched between the 2b increases, the moment of inertia of the drum 10 is increased. The moment of inertia I, the rotational torque T, the angular acceleration d 2 theta / dt 2 When, Newton's second law of motion to the rotational motion is given by the following equation.
　　　　　　= I × T (d 2 theta / dt 2 ) · · · (1) formula

[0028]

　Constituted drum drive source 20 by a motor or the like, given a rotation torque in a clockwise or counterclockwise direction to the drive shaft 21a, rotatably fixed drive roller 21b is rotated in the drive shaft 21a. A pulley (not shown) of the pulley 21b and the drum 10 of the drum drive source 20 is connected through a drive belt 15. Drive belt 15 conveys the rotating torque drum driving source 20 applied to the rotating shaft 10a, is rotated in a clockwise or counterclockwise direction of the drum 10 about the axis of rotation 10a.

[0029]

　The drum 10 and the reel 31 are connected by the tape 2a via a driven roller (idler rollers) 3. When the drum 10 rotates in the clockwise direction about the rotary shaft 10a, the reel 31 is rotated counterclockwise around the rotation shaft 31a of the reel 31.

[0030]

　The drum 10 and the reel 32 are connected by the tape 2b through the three driven rollers 4-6 and the tape speed detection unit 7. Tape speed detector 7, for example, by reading the rotational speed of the roll is pressed against the surface of the tape 2b, to detect the tape speed of the tape 2b. When the drum 10 rotates in the clockwise direction about the rotary shaft 10a, the reel 32 is rotated counterclockwise around the rotation shaft 32a of the reel 32.

[0031]

　Reel drive source 40 is constituted by a motor or the like, it rotates the pair of reels 31 and 32. Reel drive source 40, when the drive shaft 41a gives a rotational torque in a counterclockwise direction or clockwise direction, fixed to the drive shaft 41a a drive gear (drive rotor) 41 by gears (drive transmitting rotary body) 42 is the axis 42a for rotation about a.

Incidentally, the reel speed detecting unit 31b, 32 b may be either one provided configuration of the reel 31.

[0033]

　Paper sheet storage mechanism includes a drum controller (not shown), the reel control unit, and a torque limiter in Fig.

[0034]

　Figure 2 is a functional block diagram of the paper sheet storage mechanism, the drum controller 8 was not shown in Figure 1, the torque limiter 33 and the reel control unit 50 is illustrated.

[0035]

　Based on FIG. 2, the drum controller 8, the function of the torque limiter 33 and the reel control unit 50 will be described.

[0036]

　Drum controller 8 is a section for controlling the drum drive source 20 based on information from the tape speed detection unit 7. Drum controller 8 controls the drum drive source 20 as the tape speed tape speed detecting section 7 has detected becomes constant.

[0037]

　Reel control unit 50, the tape speed and the reel speed detecting section 31b where the tape speed detection unit 7 detects, based on a reel speed 32b detects, so that the tape 2a, and 2b have a constant tension, the reel drive a portion for controlling the source 40.

[0038]

　When the drum 10 for accommodating the note 1, the drum drive source 20 rotates the drum 10 in the direction of winding the tape 2a, 2b. Drum controller 8 controls the drum drive source 20 as the tape speed tape speed detecting section 7 has detected becomes constant.

[0039]

　Reel control unit 50, the reel speed detecting unit 31b, 32 b is reel speed detected is deceleration control of the reel driving source 40 so as to be smaller than the tape velocity detected tape speed detector 7. Thus, the reel speed when deceleration control the reel drive source 40 so as to be smaller than the tape speed, the drum 10 will be wound in a state of pulling the tape 2a, 2b. Reel control unit 50, a tape 2a, although the deceleration control as wound on the drum 10 in a state of pulling constant 2b, tape 2a, when the force 2b is pulled becomes too large, the tape 2a, 2b extends like problems will be caused of.

[0040]

　As such does not occur inconvenience, the torque limiter 33 is incorporated via a torsion spring (not shown) between the reels 31 and 32 rotating shaft 31a, and 32a. The torque limiter 33 has reel rotation shaft 31a, a rotational torque is applied above a predetermined value to 32a rotating shaft 31a, a function of idling the 32a.

[0041]

　Meanwhile, when the drum 10 is fed out banknotes 1, the reel control unit 50, the reel driving source 40 as the reel speed detecting unit 31b, 32 b is reel speed detected is larger than the tape velocity detected tape speed detection section 7 to accelerate control. Thus, the reel speed when acceleration control of the reel driving source 40 so as to be larger than the tape speed, the reel 31 and 32 would be wound in a state of pulling the tape 2a, 2b.

[0042]

　Reel control unit 50, the reel 31 and 32 tape 2a, although acceleration control as wound in a state of pulling 2b, tape 2a, when the force 2b is pulled becomes too large, the tape 2a, 2b extends like problems will be caused of.

[0043]

　As such does not occur inconvenience, the torque limiter 33 is incorporated via a torsion spring (not shown) between the reels 31 and 32 rotating shaft 31a, and 32a. The torque limiter 33, rotation shaft 31a, and has an applied rotation torque equal to or greater than a predetermined value 32a rotating shaft 31a, a function of idling the 32a.

[0044]

　Reel control unit 50 is a tape 2a, 2b controls the reel drive source 40 so that the tensioned state, the torque limiter 33 is the rotation axis 31a, equal to or greater than a predetermined value 32a rotational torque is applied when the reel 31, 32 rotary shaft 31a, by idling the 32a, tapes 2a, it becomes possible to perform the winding or unwinding with a constant tension without 2b loosening.

[0045]

(Embodiment operation)
　An operation of the embodiment of the present invention, the operation and at the time of (I) winding, operation and during (II) feed, (III) and the operation of the storage amount of the banknotes in different states, the divided it will be described.

[0046]

　Operation at (I) winding
　diagram 7 (a), FIG. 7 (b) is a diagram for explaining the winding operation of the paper sheet in the paper sheet storage mechanism embodiment of the present invention. 7 (a) is a view showing a moment that attempts to start the winding of the sheet, not yet paper sheet is accommodated. 7 (b) is a diagram showing a state where the paper sheet is accommodated wound on Hasame are in the drum 10 during the tape 2a, 2b, a plurality of sheets are accommodated .

[0047]

　First, with reference to FIGS. 1 to 3, FIG. 7 (a), the based on FIG. 7 (b), the operation will be described winding of the bill 1 as a paper sheet.

[0048]

　A drum drive source 20 and the drum 10 is connected by a drive belt 15. When the winding of the bill 1, the drum 10 by the pulley 21b of the drum drive source 20 rotates about the drive shaft 21a of the drum 10 is rotated clockwise. Tape 2a, by the end surface of the 2b is attached to the drum 10, the tape 2a, 2b are wound on the drum 10.

[0049]

　In this case, it makes measurements at an encoder (not shown) the speed of the tape 2 itself by a tape speed detection section 7. Drum controller shown in FIG. 2 8, so that the rotational speed of the drum 10 to the same speed as the conveying speed of the note 1 to the escrow unit 140 immediately before shown in Figure 3 in response to the measured tape speed to control to.

[0050]

　By tape 2a, 2b is discharged from the reel 31, the reel 31 itself is rotated. During winding, the rotation speed of the reel 31 and 32, since the diameter of the reel 31, 32 is reduced by a decrease in the residual amount of tape, gradually changes at a high speed. In this case, to detect the speed of the reel 31 reel speed detecting unit 31b, in 32b. Reel control unit 50, the reel speed detecting unit 31b, 32 b is reel speed detected is decelerated controls the reel drive source 40 so as to be smaller than the tape speed tape speed detection section 7 has detected. The speed difference of the time are overcome by idling the rotation shaft 31a of the reel 31, the torque larger than a predetermined value in the torque limiter 35 built into 32a applied.

[0051]

　Further, by controlling so as to approach the reel speed as possible tape speed reduces the slippage of the torque limiter 35, the torque limiter 35 is higher lifetime. Further, reduced load per angular velocity by controlling small relative velocity between the tape speed and the reel speed, the high speed easily accommodated.

[0052]

　(II) operation during unwinding
　Figure 8 is a diagram for explaining the delivery operation of the paper sheets in the paper sheet storage mechanism embodiment of the present invention. 8 (a) is a diagram showing a feeding course of the operation of the paper sheet, FIG. 8 (b) is a diagram showing the moment when the last one of the sheets is fed.

[0053]

　1, with reference to FIG. 2, FIG. 8 (a), based on FIG. 8 (b), the operation will be described feeding of the note 1.

[0054]

　When the reel driving source 40 gears provide the driving force (the drive rotor) 41, the rotational torque gear (drive transmitting rotary body) 42 is rotated, is transmitted via a drive belt 35, a pair of reels 31, 32 but it rotates in the direction for winding tape 2a, the 2b. Reel drive source 40, first, the rotation shaft 31a of the reel 31 and 32 at maximum slightly faster rate than the reel speed of computational controls so as to start the rotation of 32a. On the other hand, the drum drive source 20 is a tape 2a about the driving shaft 21a of the drum via a pulley 21b, to rotate the drum 10 in a direction to feed the 2b, ejects tape 2a, 2b and the note 1.

[0055]

　Drum controller 8 controls the drum driving source 20 by the information from the tape speed detection unit 7. For example, it controls the drum drive source 20 as the tape speed tape speed detecting section 7 has detected becomes constant. On the other hand, the reel control unit 50, the reel speed is controlled reel driving source 40 so as to be larger than the tape speed.

[0056]

　In practice, it is not possible to tape the amount of the drum drive source 20 Kuridaseru only wound on the reel 31, the reel 31 and the rotary shaft 31a, 32a will be slipping through the torque limiter 33.

[0057]

　By reel speed is controlled to be larger than the tape speed, the rotary shaft 31a, the speed difference between 32a rotational speed and reel speed of results. When the torque due to the speed difference becomes equal to or higher than a predetermined value, the speed difference is eliminated by the torque limiter 33 idles. In this case, to detect the reel speed in the reel speed detecting unit 31b, 32 b, the rotation shaft 31a of the reel, to approximate the rotational speed of the 32a of the rotational speed of the reel 31, to minimize the slippage of the torque limiter 33 It is suppressed.

[0058]

　Operation of (III) of stored banknotes in different states
　9 are diagrams banknotes rocks in the embodiment of the sheet paper storage mechanism of the present invention will be described the operation of the state which is not accommodated.

[0059]

　First, FIG. 9, almost all of the tapes 2a, 2b are wound on reels 31 and 32, the drum 10 is a state in which no tape 2a, 2b is wound. When this state, the diameter of the drum 10 is smallest, the diameter of the reel 31 and 32 the largest. Tape 2a in this state, when taking or feeding up the 2b, to the tape speed constant, increasing the angular velocity of the smaller drum 10 in diameter, is necessary to control small angular velocity of large reels 31 and 32 with a diameter is there.

[0060]

　Figure 10 is a diagram for explaining the operation of the state where the paper sheet is housed half of storable amount in the embodiment of the sheet paper storage mechanism of the present invention.

[0061]

　Next, FIG. 10, the reel 31, 32 and the drum 10, a state where the entire half of the tape 2a, 2b is wound. Tape 2a in this state, when taking or feeding up the 2b, to the tape speed constant, it is necessary to control the moderate angular velocity of the reel 31, 32 and the drum 10.

[0062]

　Figure 11 is a diagram for explaining the operation of the state where the paper sheet is accommodated all of storable amount in the embodiment of the sheet paper storage mechanism of the present invention.

[0063]

　Further, FIG. 11, almost all of the tapes 2a, 2b are wound around the drum 10, the reel 31, 32 is a state in which no tape 2a, 2b is wound. Tape 2a in this state, when taking or feeding up the 2b, to the tape speed constant, to reduce the angular velocity of the large drum 10 in diameter, is necessary to control a large small angular speed of the reel 31 diameter is there.

[0064]

　As described above with reference to FIGS. 9 to 11, the tape 2a to reel 31, 32 and the drum 10, depending on the winding state of 2b, as the tape speed is constant, the reel 31, 32 and the angular velocity of the drum 10 is controlled. With such control, it is possible to reduce the speed difference between the reel speed and the tape speed. By reducing the velocity difference, the rotary shaft 31a of the reel 31, the torque applied to 32a minimizes the slippage of the torque limiter 33 idles to be a predetermined value or more.

[0065]

(Effects of Embodiment)
　Embodiment of a paper sheet storage mechanism of the present invention, the torque limiter 33 causes the idling rotation shaft 31a of the reel 31, the applied torque of a predetermined value or more 32a rotating shaft 31a, and 32a . Thus, even when performing case or fast winding to the increased amount of storage of the paper sheet, it can provide a paper sheet storage mechanism capable of taking up the tape with a predetermined tension without loosening.

[0066]

　According to the control method of the embodiment of the sheet paper storage mechanism of the present invention, the tape 2a to reel 31, 32 and the drum 10, depending on the winding state of 2b, as the tape speed is constant, the reel 31 , the angular velocity of 32 and the drum 10 are controlled. Thus, since it minimizes slippage of the torque limiter 35 can be life of the torque limiter 33.

[0067]

(Modification)
　In the description of the paper sheet storage mechanism and a control method of the embodiment of the present invention, includes a torque limiter 33 which reels 31 and 32 runs idle and the rotary shaft 31a, a torque larger than a predetermined value 32a applied have been described are mechanism, the rotation shaft 31a of the reel, 32a and connected to the reel 31 via the one-way clutch not shown, the tape 2a to lock stopped when the drum 10 winds the tape 2a, 2b, 2b may be so as to generate tension in.

[0068]

　Further, when the drum winding, by holding excitation stop the reel driving source 40, it is also possible to generate a tension in the tape 2a, 2b.

[0069]

　Furthermore, even when the drum winding, performs rotation control similar to the rewinding, when the drum winding can also control the rotation at a slightly slower speed than the actual rotational speed measurement value of the reel.

[0070]

　In this embodiment, winding the bill 1 at a pair of tape, is performed the feeding will be described, not limited thereto, wound in one tape, feeding is also possible. Further, in the embodiment, although a single reel drive source, it is possible to provide a driving source for each reel.

[0071]
