In the above structure, a predetermined number of banknotes P, P
When paying out the bills from the bill payout opening 27 on the customer side, the fed bills P, P are fed out one by one from the bill storage 3 of the safe unit 7 by the feeder 11 and the vertical conveyance path 19 and the horizontal conveyance path. When the banknotes P, P, which are sequentially stacked on the lower rotation conveyor belt 49 of the temporary holding section 25 through 23, reach a predetermined number, the drive motor 67 is driven to rotate in the normal direction, thereby the rack and pinion mechanism 75. The first main unit 60 that moves up the lower main unit 60 via
By rotating the second cams 95 and 97 in the counterclockwise direction by a predetermined angle, the front end portions of the vertically rotating transport belts 53 and 49 are directed to the bill payout opening 27 via the upper and lower unit arms 66 and 61. The belts 53 and 49 are conveyed to the banknote payout opening 27 by rotating up to the uppermost position and rotating the belts 53 and 49 in the conveyance direction of the banknote bundles P and P (FIGS. 3A and 3B).
). A rack for converting the rotational force of the drive motor 67 into an elevating force as an ascending / descending rotation mechanism for sandwiching the stacked banknotes with the upward rotating conveyer belt 53 by raising the downward rotating conveyer belt 49 in this manner. Since the pinion mechanisms 75 and 73 are used, ascending / descending operation is reliably performed even when the driving force of the driving motor 67 is small compared to the conventional type in which the bills P and P are clamped only by the rotating action of the cam. Therefore, the motor 67 can be downsized and power can be saved.

On the other hand, in order to pay out the banknote bundles P, P from the banknote take-out opening 31 on the operator side, the vertically rotating conveyor belt 5 is used.
The driving motor 67 is driven so that 3, 49 are positioned on the same plane as the horizontal transport path 23 (horizontal position), and the vertically rotating transport belts 53, 49 and the second and third transport belts 45, By reversing 47, the banknote bundles P, P sandwiched between the vertically rotating transport belts 53, 49 are horizontally transported.
The paper money is nipped and conveyed to the banknote take-out opening 31 through the 3 and the take-out / conveyance path 33 (FIGS. 4A and 4B). Thereby, the bill outlet 3
Even when the banknotes P, P are taken out from 1, the banknotes P, P are sandwiched by the rack and pinion mechanisms 75, 73 with a strong force, and in addition, when the banknotes are taken out, the vertically rotating conveyor belt 53 is temporarily moved. , 49 are not raised toward the bill payout opening 27, the conveyance path does not have a U-shape, and a bill slip does not occur even if there are a large number of conveyed bills.

Here, when various sensors such as a timer and an abnormality detection sensor (not shown) detect an abnormality such as a bill abnormality, a double feed, a miscount, and a conveyance abnormality when depositing the bills P in the temporary holding section 25, Alternatively, when the paid-out banknotes P, P are not taken out within a predetermined time, such as when the user forgets to receive the paid-out banknotes P, P and leaves the device, the vertically rotating conveyor belts 53, 49 are collected. By driving the driving motor 67 so as to face the areas 35 and 37 and rotating and driving the vertically rotating transport belts 53 and 49 in the bill delivery direction, the banknote P sandwiched between the vertically rotating transport belts 49. , P are collected in the banknote collection areas 35, 37 through the drop opening 39 of the banknote collection box 5 (see FIGS. 5 (a) and 5 (b)). In this case, the switching gate 41 performs the switching operation by the drive mechanism (not shown) depending on whether the banknotes collected in the collection areas 35 and 37 are reject banknotes or uncollected banknotes. If the ATM collects the forgotten banknotes P, P even once, the ATM
It is preferable that the bill payout function is stopped.

After that, by driving the driving motor 67, the vertically rotating conveyor belt 53, via the rack and pinion mechanisms 75, 73 and the upper and lower unit arms 65, 61.
49 is returned to the initial position.

The present invention is not limited to this, and the vertical rotation mechanism for the vertical rotation conveyor belts 53 and 49 may have another structure. Further, although the present invention is applied to a bill payout device, it is needless to say that the same effect can be obtained even when applied to a device that pays out tickets other than bills.

[0042]

Since the present invention is constructed and operates as described above, a rack connected to the drive source is connected to the drive mechanism for vertically moving the vertically rotating conveyor belt by connecting the cam to the drive source. By adding a pinion mechanism, the lower rotating conveyor belt can be pushed up toward the upper rotating conveyor belt, and multiple sheets of paper accumulated between both belts can be pinched with a strong force. As a result, the driving force of the driving source can be reduced as compared with the case where the paper sheets are sandwiched, and the overall size of the mechanism and the cost can be reduced.
