It is formed by the detection part 103 integrally protruding in the center part of the joint part 101. FIG. The sensor lever 100 has a support shaft 96 interposed between the first support portions 94 and 94 of the support member 91 via the support shafts 96 inserted into the shaft holes 102 a and 102 a and the long holes 94 a and 94 a of the support member 91. It is swingably supported as a swing center. At the same time, the sensor lever 100 is supported by the first support portions 94 and 94 movably because the support shaft 96 that supports the sensor lever 100 is slidably held in the long hole 94a. .

  The first torsion coil spring 92 is wound around the support shaft 96 and a connecting portion 92 a provided at the center is engaged with the lower end of the engaging portion 101 of the sensor lever 100. The second torsion coil spring 93 is wound around the shaft 97, and both end portions 93 a and 93 a are engaged with the lower ends of both end portions of the support shaft 96. In such a configuration, when the support member 91 is attached to the first case 4, the sensor lever 100 is rotated counterclockwise in FIG. 10 about the support shaft 96 by the torsional moment of the first torsion coil spring 92. The engagement portion 101 is urged in a direction to engage with the notch 86 of the reverse rotation restricting wheel 85. That is, the sensor lever 100 allows the conveyance roller 71 to rotate when the conveyance roller 71 rotates in the bill conveyance direction (counterclockwise in the figure).

In this state, when the transport roller 71 is slightly rotated clockwise, the support shaft 96 is configured to be movable rightward in the long hole 94a against the torsional moment of the second torsion coil spring 93. . In FIG. 12, 110 is a sensor attached to the sensor bracket 111. When the engaging portion 101 of the sensor lever 100 is engaged with the notch 86, this engagement is detected by the detecting portion 103, and the second motor. The driving of 70 is stopped.

  Next, the operation | movement which conveys the banknote 9 determined to be a true bill in the banknote identification device 2 to the banknote accommodating part 3 in such a structure is demonstrated. The electromagnetic solenoid 50 is not energized in advance, and the rod 50a moves forward as shown in FIG. 6A, and the first to third pinch rollers 25 to 25 of the first bill transport means 11 are moved forward. 27 is in contact with the drive belt 24 as shown in FIG. Further, the groove 80 of the conveying roller 71 is located at the initial position shown in FIG.

  In this state, when the bill 9 is inserted from the bill insertion slot 10 and the presence of the bill 9 is detected by a sensor (not shown), the first motor 20 is driven in the forward direction. Accordingly, the inserted bill 9 is conveyed in the direction of arrow A while the thickness direction is held between the drive belt 24 and the first pinch roller 25 and the posture of the inserted bill 9 is held in the bill insertion slot 10. At this time, the lower end of the banknote 9 abuts on the guide ridge 14, is guided by the guide ridge 14, and is conveyed in the direction of arrow A.

  Further, the banknote 9 is conveyed in the direction of arrow A by the drive belt 24 and the first pinch roller 25, so that the groove 80 of the conveyance roller 71 coincides with the surface of the guide protrusion 14 as shown in FIG. Therefore, the bill 9 is conveyed in the direction of arrow A with the lower end 9 a entering the groove 80 from the opening end 81 of the groove 80 of the conveying roller 71 and the lower end abutting against the groove 80. . When the front end of the banknote 9 reaches the second pinch roller 26, the banknote 9 is conveyed in the direction of arrow A by the second pinch roller 26, the first pinch roller 25, and the drive belt 24. When the front end of the banknote 9 reaches the third pinch roller 27, the banknote 9 is conveyed in the direction of arrow A by the third pinch roller 27, the second pinch roller 26, the first pinch roller 25 and the drive belt 24. Is done.

  Further, the bill 9 is conveyed in the direction of the arrow A, and the state where the rear end of the bill 9 is removed from the first pinch roller 25 (position indicated by reference numeral 9A in FIG. 1) is detected by a sensor not shown. Then, the driving of the first motor 20 is stopped, and the conveyance of the bill 9 is stopped. The position indicated by the reference numeral 9A is an identification position at which the authenticity of the banknote 9 is identified by the banknote identification apparatus 2, and each end of the banknote 9A positioned at this identification position in the direction of arrows AB is a transport roller. 71 is located on the outer side in the arrow A direction or the outer side in the arrow B direction from both ends of 71.

  When the bill identification device 2 identifies the authenticity of the bill 9 and identifies that the bill 9 is a genuine note, the electromagnetic solenoid 50 is energized. When the electromagnetic solenoid 50 is energized, the first swinging lever 52 rotates about the shaft 64A in the clockwise direction in FIG. 5 via the swinging element 51, so that the holder 43A is moved to the position shown in FIG. As shown in FIG. 2, the second pinch roller 26 is separated from the drive belt 24 because it rotates counterclockwise about the shaft 45.

  When the first swing lever 52 is rotated, the second swing lever 54 is simultaneously rotated clockwise about the shaft 64B via the transmission member 53, so that the holder 43B is moved in FIG. ), The third pinch roller 27 moves away from the drive belt 24 because the shaft 45 rotates counterclockwise about the shaft 45 as shown in FIG.

  Further, when the electromagnetic solenoid 50 is energized, as shown in FIG. 6B, the detected portion 59 of the oscillator 51 is detached from the sensor 61, and the pinch rollers 26 and 27 are separated from the drive belt 24. Is detected by the sensor 61, the second motor 70 is driven in the forward direction. By driving the second motor 70 in the forward direction, the conveyance roller 71 starts to rotate counterclockwise in FIG. By this rotation, the lower end portion 9a of the bill 9A facing the groove 80 of the transport roller 71 is bent so as to contact the peripheral surface of the transport roller 71 as the transport roller 71 rotates, as shown in FIG. The pinch roller 72 and the conveying roller 71 are sandwiched between the peripheral surfaces. Therefore, when the transport roller 71 further rotates, the banknote 9A is transported in the direction of the arrow D from the first banknote transport path 8 to the second banknote transport path 18 as shown in FIG. It is stored in.

  When a sensor (not shown) detects that the banknote 9A is stored in the banknote storage unit 3, the second motor 70 is driven in the reverse direction. By this drive, the transport roller 71 rotates in the direction opposite to the banknote transport direction (clockwise in FIG. 13), and this rotation causes the sensor lever 100 to engage with the notch 86 of the reverse rotation restricting wheel 85 as shown in FIG. When the unit 101 is engaged, the sensor 110 detects the detection unit 103, stops the driving of the second motor 70, and stops the rotation of the conveying roller 71. At this time, the support shaft 96 resists the torsional moment of the second torsion coil spring 93 even if the conveyance roller 71 is slightly rotated clockwise in the drawing due to inertia and the sensor lever 100 is pressed rightward. It moves slightly to the right in the long hole 94a. Therefore, since the load applied to the sensor lever 100 is buffered by the inertia of the transport roller 71, deformation or breakage of the sensor lever 100 can be prevented.
