To function. In FIG. 2, reference numeral 93 denotes a full sensor for detecting that the bill A is full in the bill box 19. When the full sensor 93 is operated, the drive motor 31 receives the input signal. It remains deactivated.

Next, the operation of the bill validator will be described. First, the banknote A is inserted from the banknote insertion slot 5. When the first detector S-1 detects the insertion of the bill A, the drive motor 31 is rotated in the normal direction. As a result, the bill A is conveyed by the conveyor belt 9, and during the conveyance process, the second detection unit S-2 identifies whether the bill A is genuine or counterfeit. In this case, in the case of a counterfeit product, it is returned to the bill insertion slot 5 side by the conveyor belt 9 by the reverse rotation of the drive motor 31 and cannot be inserted.

On the other hand, the real bill A that has passed the second detection unit S-2 passes through the third detection unit S-3, and outputs a command signal to send out a product etc. when the passage is completed. In this case, even if the bill is pulled back to the bill insertion slot 5 side by the illegal means, the bill is not blocked by the detection lever C3-L and is not pulled out. Next, the banknote A passes through the fourth detection unit S-4 and is supported at both ends by the temporary support member 39. At this time, the drive motor 31 reversely rotates in response to a signal from the fourth detector S-4, and rotational power is applied to the cam body 65 via the worm wheel 53. In this case, the drive motor 31 that secures a large occupied space functions as a drive motor that drives the bill pressing body 59 in addition to driving the conveyor belt 9, and thus only one drive motor is required. On the other hand, due to the rotation of the cam body 65 to which the rotational power is applied, the bill pressing body 59 descends and then moves up to perform one cycle motion. During this one cycle movement, the banknote A pressed by the banknote pressing body 59 comes to rest on the banknote support plate 75 of the banknote box 67. At this time, the banknote support plate 75 descends by the banknote pressing body 59, then rises again, and comes into contact with the restriction portion 73. As a result, the upper surfaces of both ends of the banknote A are properly placed on the banknote support plate 75 while being pressed by the restriction portion 73. Hereinafter, by repeating the above operation, the banknotes A are stacked one by one on the upper surface of the banknote support 75.

On the other hand, when the one cycle backward movement of the bill pressing body 59 is completed, the fifth detection unit S-5 detects it and the drive motor 31 is stopped.
