  The control unit 80 includes a microcomputer and is connected to the motor 36, the belt switch 68, and the detection switch 69 of the first transport unit 30. Although not shown in the figure, the control unit 80 is connected to the motor 65 of the pressing unit 60 and other devices, an external control line, and the like. The operation is to be performed. At that time, if an abnormality such as a banknote jam occurs, the operation is stopped due to an error state, and when the belt switch 68 is pressed, the error state is canceled and the initial state is reset.

  That is, as shown in the flowchart of FIG. 10, when the belt switch 68 is turned on (S1), the control unit 80 detects that the banknote storage unit 70 has been attached by the detection switch 69 (S2). (S3), when the bill storage unit 70 is not attached in step S2, the motor 36 of the first transport unit 30 is operated (S4), and the belt switch 68 is turned off (S5). 36 is stopped (S6).

  According to the banknote identification device configured as described above, when a banknote is inserted into the banknote slot 20b of the slot cover 20, the motor 36 of the first transport unit 30 is activated, and the first and second Bills are conveyed by the guide rollers 32 and 42 of the conveyance units 30 and 40. That is, the bill inserted into the bill insertion slot 20b is transported toward the rear of the main body case 10 and is transported upward from a predetermined position in the front-rear direction of the main body case 10, and the pressing unit 60, the bill storage unit 70, It is conveyed to between. In that case, the conveyed banknote passes between each light-emitting body 51 and each light-receiving body 52 of the identification part 50, and the authentication part 50 determines the authenticity and denomination of a banknote. Moreover, if a banknote is conveyed between the press unit 60 and the banknote storage unit 70, the motor 65 of the press unit 60 will act | operate and the press plate 62 will move to the banknote storage unit 70 side. As a result, the banknote is pressed toward the banknote storage unit 70 by the pressing plate 62 and is carried into the banknote storage unit 70. At that time, the pressing plate 62 moves the bill support plate 73 backward together with the bill against the spring 74, and when the pressing plate 62 returns to the standby position, the bill support plate 73 is also returned forward together with the bill by the spring 74.

  When the bill 65 is pressed by the pressing plate 62, when the motor 65 of the pressing unit 60 rotates, the rotational force is transmitted to the rotating plate 64 via each gear 66, and the rotating plate 64 rotates in a predetermined direction. Thereby, the rotational motion of the rotating plate 64 is converted into the reciprocating motion of the pressing plate 62 by the connecting member 63. At that time, the respective engagement shafts 62a of the pressing plate 62 slide in the respective engaging cylinders 61a of the unit main body 61 in the front-rear direction, so that the pressing plate 62 is guided by the respective engaging cylinders 61a and the bill support plate. It moves in the front-rear direction while maintaining the parallel state with 73.

  When the banknotes A are transported by the transport units 30 and 40, as shown in FIG. 9A, a locking lever 43 is interposed between the passage surfaces 31b and 41a of the banknote transport path B. Since the lever 43 is disposed with its tip directed in the banknote transport direction, the lever 43 is rotated to one passage surface 40a by contact with the banknote A as shown in FIG. The passage of the bill A is allowed.

  In addition, as a fraudulent act against the banknote identification device, a genuine banknote A having a tape or the like connected to the end portion is inserted, and after the product is purchased by the identification section 50 once determined to be authentic, it is stored in the banknote storage unit. When the banknote A is to be pulled out with a tape or the like, the banknote A is prevented from being pulled out as follows.

  That is, when the stored banknote A is pulled back, the leading end of the banknote A is locked to the locking lever 43 as shown in FIG. At that time, since the locking lever 43 is arranged with its tip directed in the banknote conveyance direction, even if a force in the direction opposite to the banknote conveyance direction is applied to the banknote A, the locking lever 43 is connected to the other passage surface 31b. The rotation is restricted by the contact, and the withdrawal of the bill A is prevented. Moreover, since the front end side of the latch lever 43 is received in the hole 31c, the bill A does not pass between the front end of the latch lever 43 and the other passage surface 31b.

  On the other hand, when the bill A is pulled back while the locking lever 43 is rotated to the one passage surface 41a side by the tape, for example, a tape (not shown) connected to the bill A is formed wide. The bill A passes between the front end of the locking lever 43 and the other passage surface 31b, and the locking lever 43 cannot prevent the bill A from being pulled out. However, in this case, since the bill A is pressed to the other passage surface 31b side by the locking lever 43, the tip of the bill A is placed on the step portion 31d of the other passage surface 31b as shown in FIG. 10 (b). The banknote A is prevented from being pulled out.

  Moreover, in the banknote identification device, when the first transport unit 30 is removed and maintenance is performed, the first transport unit 30 is released from the engagement with the holding portions 13 of the main body case 10 and pulled backward. As a result, the first transport unit 30 is removed to the outside. As a result, the transport belt 33 can be cleaned while being attached to the first transport unit 30, or the transport belt 33 can be removed for cleaning or replacement.

  When the transport belt 33 is cleaned without removing the first transport unit 30 from the main body case 10, the banknote storage unit 70 and the second transport unit 40 are removed from the main body case 10. At this time, when the second transport unit 40 is removed, the back side of the first transport unit 30 is exposed to the lower part on the back side of the main body case 10. Here, when the operation pin 68a of the belt switch 68 is pressed, the belt switch 68 is turned on, the motor 36 is operated, the guide roller 32 is rotated, and the transport belt 33 is operated. Thereby, the conveyor belt 33 can be cleaned while operating the conveyor belt 33.

  Thus, according to the banknote identification device of the present embodiment, the first transport unit 30 having the transport belt 33 is detachably provided on the main body case 10, so that the first transport unit 30 is removed outside and transported. The belt 33 can be cleaned or replaced, and maintenance work can be performed very easily. In this case, the first transport unit 30 has the transport belt 32 extending in the front-rear direction on one end side of the first transport unit 30 and to the lower end side of the banknote storage unit 70 on the other end side of the first transport unit 30. Since it is formed so as to extend in the vertical direction, the conveyor belt 32 does not extend long to the upper end side of the banknote storage unit 70, and the conveyor belt 32 is formed short even in a configuration in which banknotes are conveyed in the front-rear direction and the vertical direction. be able to. This eliminates the need for a tension roller for preventing the conveyor belt from slacking as in the prior art, so that the number of parts can be reduced and the troublesome work of releasing the tension roller is eliminated. Further, the cost of the conveyor belt 32 can be reduced by the shortening of the conveyor belt 32.

  Further, when the second transport unit 40 disposed in the vicinity of the first transport unit 30 is removed from the main body case 10, the back side of the first transport unit 30 is exposed to the outside, and the first Since the motor 36 for rotating the guide roller 32 of the transport unit 30 is arbitrarily operated by operating the belt switch 68 while the first transport unit 30 is mounted on the main body case 10, the first transport unit 30. The conveyor belt 33 can be cleaned over the entire circumference while operating the conveyor belt 33 without removing the belt. Thereby, it is possible to clean the conveyor belt 33 other than the portion located on the side of the passage surface 31b of the first conveyor unit 30, and the maintenance of the conveyor belt 33 can be performed reliably.

  Further, since the motor 36 of the first transport unit 30 is operated by the belt switch 68 only when the banknote storage unit 70 is removed from the main body case 10, the banknote storage unit 70 is attached to the main body case 10. When the belt switch 68 is operated, there is an advantage that the motor 36 does not operate and the transport belt 33 is not operated unnecessarily.

  Further, when the bill storage unit 70 is attached to the main body case 10, the belt switch 68 is used to cancel the error of the control unit 80 in an abnormal state. Therefore, the structure can be simplified. In addition to the operation of the motor 36, the belt switch 68 may perform operations other than the error cancellation of the control unit 80 such as a power supply state check and an LED light emission test.

  Further, since the belt switch 68 is provided so as to be interlocked with the operation pin 68a provided on the main body case 10 so as to be operable from the outside, the belt switch 68 can be operated without removing the bill storage unit 70 and other parts. Error canceling operation can be easily performed.

The locking lever 38 is urged counterclockwise in the figure by a coil spring (not shown), and one end side of the locking lever 38 projects from the passage surface 31b to the second transport unit 40 side. In addition, since the operation | movement which prevents withdrawal of the banknote by the latching lever 38 is the same as that of the said embodiment, description is abbreviate | omitted.

  Further, a protruding piece 38 b is provided on the other end side of the locking lever 38, and a lever switch 39 is provided in the unit main body 31 and located on the side of the protruding piece 38 b. The lever switch 39 includes a detection unit 39a that detects the protruding piece 38b in a non-contact manner by using, for example, an optical sensor. When the locking lever 38 is rotated clockwise in the drawing to a predetermined position, the protruding piece 38b is detected by the detecting unit 39a. It is configured to detect and turn on. The lever switch 39 is connected to the control unit 80.

That is, as shown in the flowchart of FIG. 19, when the lever switch 39 is turned on (S10), the control unit 80 detects that the banknote storage unit 70 is attached by the detection switch 69 (S11), the step S10. Returning to step S11, when the bill storage unit 70 is not attached, the motor 36 of the first transport unit 30 is operated (S1 2 ), and the lever switch 39 is turned off (S1 3 ). It stops (S1 4 ).

  In the present embodiment, when the transport belt 33 is cleaned without removing the first transport unit 30 from the main body case 10, the banknote storage unit 70 and the second transport unit 40 are removed from the main body case 10. At this time, when the second transport unit 40 is removed, the back side of the first transport unit 30 is exposed to the lower part on the back side of the main body case 10. Here, as shown in FIG. 17, when one end side of the locking lever 38 is pressed and rotated clockwise in the figure, the lever switch 39 is turned on, the motor 36 is operated, and the guide roller 32 is rotated. The conveyor belt 33 operates. Thereby, the conveyor belt 33 can be cleaned while operating the conveyor belt 33.

  Thus, according to the present embodiment, the motor 36 that rotates the guide roller 32 of the first transport unit 30 is arbitrarily operated in a state where the first transport unit 30 is mounted on the main body case 10 by the lever switch 39. As in the above-described embodiment, the conveyor belt 33 can be cleaned over the entire circumference while operating the conveyor belt 33 without removing the first conveyor unit 30. Can be performed very easily.

  In this case, since the lever switch 39 is interlocked with the operation of the locking lever 38 for preventing the withdrawal of the banknote, a dedicated part as an operation part of the lever switch 39 is not required separately, and the structure is simplified. Can be achieved.

  In the above embodiment, the locking lever 38 for preventing the withdrawal of the banknote is used as the operation part of the lever switch 39. However, the operation part is formed by other dedicated parts. Also good.
