A banknote collection box 13 is arranged. The aforementioned first denomination box 9゜second denomination box 10
．． At the top of each of the safe 11 and the temporary stacker section 12, a stacking device 142 of the present invention, a separating mechanism 15, and a feeding mechanism 16 are arranged, each of which includes an impeller receiving and guiding means. The above-mentioned parts are connected by a conveyance means, and a gate part is provided at a branch part in the conveyance means. Furthermore, a slip/card mechanism and a passbook printing mechanism are installed above the cash handling section.

0 and safe 11.

Also, according to the customer's request, the first denomination box 9 and the second denomination box 9
The banknotes B stored in the denomination box 10 can be paid out to the deposit/withdrawal port 2 through the front/back reversing mechanism 7 with their surfaces aligned.

Next, the configuration of an example of the accumulating device of the present invention including the above-mentioned impeller receiving and guiding means will be explained using FIG. 2.

A shaft 21 is rotatably supported on the frame 22.

This shaft 21 is driven by a motor (not shown). An impeller 20 serving as a receiving and guiding means for zero banknotes is fixedly attached to the shaft 21 and rotated integrally with the shaft 21.

On the circumference of the impeller 20, a plurality of blades 2OA for receiving and guiding banknotes are attached at equal intervals.

The banknotes B sent out from a conveyance path (not shown) are pinched and conveyed by conveyance rollers 26 and 27, and are conveyed by the blades 20 of the impeller 20.
It is pushed between A. Further, the banknotes B separated from between the blades 2OA of the impeller 20 are stacked on a push plate 29, which is a banknote stacking member of the storage section. The uppermost surface of the stacked banknotes B or the position of the upper end of the push plate 29 is detected by a pair of sensors, for example, a photosensor 60, provided opposite to the frame 22. This photo sensor 60 is turned on.

The QFF status signal is used to control the amount of rise and fall of a push plate 29, which constitutes a space amount control means to be described later, in accordance with the amount of banknotes B accumulated. When the banknotes B are not accumulated in the storage section, the push plate 29 is located at the uppermost position, and the photosensor 60 is in an OFF state. The push plate 29 is pressed until the photo sensor 60 is turned on before starting the receiving operation.
to determine the initial position of the push plate. Next, the push plate 29 is lowered by a set value. As a result, a space is formed between the impeller and the push plate or the upper end of the stacked banknotes. This setting value is because the maximum number of normal banknote transactions is 100 pieces.
A new ticket requires a minimum length of 10m, and a circulating ticket with a circulation rating of 1.5 requires a minimum length of 15m. However, in reality, new tickets and circulating tickets are mixed, so the above setting value may be set to about 20 to 25 mn. In this state, when the impeller 20 is driven to receive and receive the banknotes B, the conveyed banknotes B received and received by the impeller 20 are held between the blades 20A of the impeller 20 and as they rotate, the banknotes B are moved toward the storage section. The impeller 2 is fed into
0, fall through the space, and are sequentially stacked on the push plate 29 or on the already stacked banknotes.

As a result, the banknotes B are sequentially accumulated in the storage section. When a certain amount of banknotes B are accumulated in the storage section, the photosensor 60 detects the uppermost surface of the banknotes B that have been accumulated. Therefore, the photosensor 60 is in an ON state. The ON state signal from the photosensor 60 is applied through the control circuit 32 to a drive motor 33 of a space amount control means, which will be described later. As a result, the drive motor 33 rotates the push plate 29 in the downward direction, thereby lowering the stacked banknotes. As the group of banknotes descends, the photosensor 60 is turned off again. Due to the OFF state signal of the photosensor 60, the push plate 2 is turned off again.
The initial value of 9 is determined, and the push plate 29 is lowered by a set amount during stacking to form a new space.

Since the amount of space can be set arbitrarily, the amount of space may be set to be large enough so that the impeller 20 and the uppermost surface of the stacked banknotes B do not come into contact with each other until one receiving operation is completed.

In either case, since a predetermined amount of space is always formed before the start of the receiving operation, stable stacking of banknotes is possible.

As described above, in this embodiment, the banknote pressing means in the paper sheet separation/retrieval state is used as a space control means in the paper sheet stacking state.

Next, the configuration of the above-mentioned space amount control means will be explained.

The push plate 29 receives and receives banknotes B accumulated in the storage section. This push plate 29 is supported by a guide shaft 34 and a screw shaft 35 provided on the frame 22, and is driven in the vertical direction. That is, when the rotation of the drive motor 33 is transmitted to the screw shaft 35 by the belt 36,
Since the screw shaft 35 rotates forward and backward, the push plate 29
It is pushed up and down via a nut 37 that engages with this screw shaft 35. At this time, when stacking banknotes B in the storage section, the top surface of the stacked banknotes B is detected by a signal from the photosensor 60, and a space is formed by lowering the push plate. When the receiving and receiving operation is started and the banknotes B are accumulated and the photosensor 60 detects the uppermost surface of the banknotes B, the push plate 29 is lowered by a set amount. As a result, the amount of space between the impeller 20 and the top surface of the stacked banknotes B is set during stacking or before the next receiving operation.

If the set space amount is small, the photo sensor 6
0 is in the ON state, but in this case, the push plate 29 is controlled to continuously descend by a set amount in order to set a new space while banknotes are being stacked.

Next, the operation of the banknote stacking device described above will be explained. When receiving and collecting banknotes B sequentially conveyed by the conveyance rollers 26 and 27 in the storage section, as shown in FIG. rises to. The photosensor 60 applies its signal to the control circuit 32, so the control circuit 32 applies the signal to the drive motor 33.
Add a stop signal to. This causes the push plate 29 to stop.

Through the above operations, the initial position of the push plate 29 for collecting and receiving banknotes B is determined regardless of whether or not there are banknotes stacked. Next, the push plate 29 is lowered by a predetermined amount to form a predetermined amount of space before starting the receiving operation.

In this state, the operation of receiving and accumulating banknotes B is started. That is, the impeller 20 rotates in the counterclockwise direction in FIG. 2 in synchronization with the conveyance of the banknotes B to be stacked, and the banknotes B held by the conveyance rollers 26 and 27 are transferred to the blades 2OA of the impeller 20. pushed in between. This banknote B has 20 feathers.
It is held by A and rotated by the impeller 20 until it engages with the stopper 31. Thereafter, the banknotes B collide with the stopper 31 and separate from the impeller 20, fall through the space, and continue to be accumulated on the push plate 29 or the already stacked banknotes B in sequence. During this time, the push plate 29 is stopped, but if the set space amount is small and the stacked amount of banknotes B increases, the photo sensor 60
will operate. The drive motor 33 is actuated by the ON state signal of the photosensor 60 to lower the push plate 29.

When the push plate 29 is lowered, the photosensor 60 is turned off and returns to its initial state. As a result, a predetermined space is again formed between the impeller 20 and the stacked banknotes B, and the banknotes B can be continuously received and stacked. That is, each time the photosensor 60 operates in accordance with the amount of banknotes B accumulated, the push plate 29 descends to form a new space, so that a state in which banknotes B can be stably received and accumulated is always maintained. I can do it.

In addition, although the above-mentioned Example demonstrated the structure which accumulates banknotes in the horizontal direction, it is applicable also when a banknote is in an upright state.

Further, in each of the embodiments described above, a case has been described in which banknotes are handled as paper sheets, but it goes without saying that similar effects can be obtained with other paper sheets such as slips.

〔Effect of the invention〕

According to the present invention, regardless of the amount of paper sheets accumulated in the storage section, paper sheets can always be stably received and accumulated, and the paper sheet accumulation performance can be improved.
