A guide (not shown) that regulates the direction of the bill is provided in the space between the payout unit and the transport unit, and between the transport unit and the payout unit, so that the bill is smoothly transported without being caught. It is supposed to be.

Next, the method of use and operation of the simple dispensing machine configured as described above will be described.

First, by rotating the drive motor 19 in a predetermined direction, each pulley 18 is transmitted via each of the transmission belts 20, 21, 22, and 23.
a ', 15a', 11a ', 10a', 6a ', 6b', 7a ', 7b' are rotated in the directions of the arrows shown in FIG. As a result, each drive roller 18a, 15a, 11a, 10
a, 6a, 6b, 7a and 7b rotate in the directions of the arrows shown in FIG.

Thereby, the bills of different denominations stored in the stackers 1A and 1B are kicked out by a predetermined number of sheets sequentially according to a predetermined order by the kick-out rollers 6a and 6b provided at the bottom of the stackers 1A and 1B. Feeding roller
By passing between 7a (or 7b) and the driven rollers 8a, 9a (or 8b, 9b), the kicked-out banknotes are peeled in a two-ply state, Are sent out one at a time. When the bills conveyed at regular intervals by the transport unit 3 are confirmed by the photo sensor to be in a normal state (a state in which the bills are usable and are sent one by one at a predetermined interval), It is sent from the end of the transport section 3 to the dispensing section 4 and the dispensing belt 14 of
Is conveyed to the dispensing port 13 and is sequentially accumulated in the dispensing port 13 from below. At this time, the banknotes accumulated in the outlet are lifted upward at predetermined intervals by an accumulation vehicle (not shown) so that the banknotes can already enter the lower side of the accumulated banknotes. It has become. When the bills sent to the transport unit 3 are not in a proper state, the bills are collected from the dispensing belt 14 to the collection box 16 by the collection belt 17 of the reject unit.

Then, after it is confirmed by the photo sensor that the banknotes kicked out from the kicking-out section 2A or 2B have reached a predetermined number, the pulleys 6a 'and 6b' and the pulley 6
The clutch between "a" and "6b" is activated, and the kick roller 6a
And 6b stop, whereby the banknotes left in the middle of the transport unit 3 and the dispensing unit 4 are transported to the last dispensing port 13 and accumulated.

Further, after it is detected by the photo sensor that a predetermined number of banknotes have been accumulated in the dispensing port 13, the pulleys 6a 'and 6a "and 6b' and 6b" of the kick-out roller are again engaged by the clutch. Connected and drive motor 19
Are rotated in reverse, the respective drive rollers connected by the drive motor 19 and the respective transmission belts are rotated in reverse, so that the kick-out rollers 6a, 6b are rotated in reverse, and the stackers 1A,
The bill slightly kicked out from the bottom of 1B is returned to a predetermined position on the stacker.

However, at this time, the drive rollers 15a, 18a and the pulley 15a ',
Since the reverse rotation preventing mechanism 26 is provided between the payout belt 18 and the collection belt 17, the reverse rotation prevention mechanism 26 is not provided. That is, at the time of the reverse rotation of the motor, the power transmission one-way clutch 26a idles, so that the motor driving force is not transmitted to the rotary shaft 28. Nevertheless, even if the rotation is caused by the idling torque of the rotation shaft 28, the rotation plate 26c having the one-way clutch that is to rotate together with the rotation shaft 28 when the motor rotates in the reverse direction is braked by the tip brake portion of the rotation prevention plate 26d. Therefore, the reverse rotation of the dispensing drive roller 15a and the collection drive roller 18a supported by the rotating shaft 28 is reliably prevented. For this reason, the banknotes once accumulated in the dispensing port 13 are returned by the dispensing belt 14, making it difficult to remove the banknotes from the dispensing port 13, or the collection box 16 of the reject unit 5.
The banknotes that have not been completely collected and have been caught on the collection belt 17 are not fed back by the collection belt side.

As described above, in the simple type dispensing machine of the present embodiment, the reverse rotation prevention mechanism 26 is provided on the pulleys of the dispensing drive roller 15a and the collection drive roller 18a. , 1B, the bill slightly kicked out,
Even when the banknotes are to be stored in the stackers 1A and 1B, the banknotes accumulated in the payout port 13 are not returned by the payout belt 14. In addition, in the case of this embodiment, the reverse rotation prevention mechanism is provided for two of the dispensing drive roller 15a and the collection drive roller 18a, so that the load on the dispensing side is larger than when one is provided, There is no twisting due to the idle torque on the transport side.

In the above embodiment, the dispensing drive roller 15 was used.
Although the reverse rotation prevention mechanism is provided on both the a and the collection drive roller 18a, it may be provided only on the dispensing drive roller 15a.

[Effects of the Invention] As described above in detail, according to the simplified type dispensing machine of the present invention, a dispensing drive roller (second drive roller).
And a recovery drive roller (third drive roller), at least a dispensing drive roller is provided with a reverse rotation prevention mechanism for preventing reverse rotation. Trying to return to the home position of the stacker,
Even when the motor is reversed to reverse the kick-out roller (first drive roller), at least the dispensing drive roller does not reverse, and therefore, the dispensing driven by the dispensing drive roller. There is an effect that the banknotes stacked on the dispensing port are not reversed by the dispensing belt. In addition, since the rotating plate and the detent plate slide only when a braking force is required, an excessive load is not applied to the drive source at the time of forward rotation. Wear can be prevented.
