2. Description of the Related Art Conventionally, an automated teller machine, which is a paper sheet handling device for handling paper sheets, for example, banknotes, is installed in a store such as a bank. This automatic teller machine operates based on the operation of the customer and conducts deposit and withdrawal transactions.

In this device, bills are inserted or
It has a dispensing unit to be dispensed. The banknotes thrown into the dispensing section are taken into the apparatus and subjected to deposit processing. In addition, at the time of withdrawal, a withdrawal transaction is performed by paying out a bill from the device, paying it out to the ejecting unit, and withdrawing the bill from the ejecting unit by the customer.

[0004]

It is sufficient that the paper sheets are normally inserted into and ejected from the ejection portion as in the conventional case. For example, the paper sheets are halved in the longitudinal direction or wrinkled. hand,
In the case of falling to the bottom of the ejecting unit, the detection sensor cannot detect it, although not all of the inserted paper sheets have been delivered. Further, even if the customer does not remove all the paper sheets dispensed to the outlet, the detection sensor will not detect the presence of the paper sheets.

Therefore, the processing ends even though the paper sheet or the like still remains at the bottom of the ejection portion. This causes trouble with the customer. Therefore, no matter how the paper sheet exists in the paper sheet of the ejection unit, a method of providing a large number of detection sensors so that it can be detected and a method of detecting it can be considered, but this increases the cost of the device, Further, since it is necessary to process the outputs of a large number of detection sensors, the control becomes complicated or the circuit becomes complicated.

Moreover, since the installation places of the guide, the feeding roller and the like are limited, the detection sensor cannot be provided at a free position. Therefore, it is an object of the present invention to provide an apparatus capable of detecting such an abnormality of a paper sheet by utilizing the current configuration of the apparatus without increasing the cost.

FIG. 2 is a schematic view of the automatic depositing / dispensing device. FIG. 3 is a block diagram of the automatic depositing / dispensing apparatus. FIG. 4 is a configuration diagram of the ejection unit.

FIG. 5 is a diagram showing the detection position of the detection sensor. FIG. 6 is a deposit processing flow. FIG. 7 is a withdrawal processing flow. FIG. 8 is a bill detection processing flow. 9 to 11 show the bill detecting operation of the dispensing unit.

An automatic depositing / dispensing apparatus as shown in FIG. 2 is shown in FIG.
And processing is performed as shown in FIG. That is, when the customer detects that the deposit transaction is selected by the selection button of the input unit 32, the deposit transaction is started (step 50).
1). As this input unit, various types of input means such as a key pressing type and a touch panel type can be considered.

First, an instruction is output to the display 31 to insert the cash card brought by the customer into a card insertion slot (not shown) (step 502). Further, the display 31 is instructed to insert a bill (step 503), and at the same time, the shutter 11 is opened (step 504). Details of the opening / closing mechanism of this shutter are described in Japanese Utility Model Laid-Open No. 63-53172.

When the customer inserts a bill into the dispensing unit 1 and closes the shutter (step 505), the bill in the dispensing unit 1 is detected (step 506). When the detection sensor 2 detects that the bill is present in the dispensing unit 1, the pressing plate is moved to the delivery roller 3 side (step 507). If there is no difference in the detection of bills, the shutter 11 is opened and an instruction is again displayed on the display to insert the bills into the dispensing unit 1.

For a detailed description of the drive mechanism for pressing the pressing plate, the timing of pressing, etc., see JP-A-56-1656.
No. 44, or Japanese Utility Model Laid-Open No. 1-160578. As a result, the bill feeding roller 3 is rotated while pressing the bill against the feeding roller 3, so that the bills are conveyed one by one to the discriminating unit 11 which is the processing unit 6 and the like by the conveying path indicated by the thick line in FIG. (Step 508).

The bills dispensed by the discrimination section 11 are
Discrimination of authenticity of bills, denomination, bills that have been worn out and need to be collected because they are worn out, whether they are bills that were conveyed skewed, and whether they were double-feed bills. Is performed (step 509). Based on the result of the discriminating section 11, a normal banknote path 12 and a defective banknote path 13 are discriminated by a gate (not shown), and are temporarily held in the deposit pool section 14 and the return / payment pool section 15 (step 510).

When there are returned banknotes, the pressing plate 5 is moved in the direction opposite to the pressing direction (step 512). Further, when the number of returns is not the predetermined number, the returned banknotes are moved from the withdrawal and withdrawal pool section 15 to the dispensing section 1, the shutter 7 is opened, and the customer is instructed to reinsert the banknotes on the display 31 ( Step 514).

The shutter 7 is closed (step 515), and if there is a bill, the processing is repeated from step 507 (step 516). If the number of returns reaches a predetermined number as a result of discrimination several times, all banknotes are moved from the deposit pool unit 14 and the return dispense pool unit 15 to the dispensing unit 1 (step 517, The customer is instructed to open the shutter and remove the bill (step 519).

When the bill is taken out, the shutter 11 is closed (step 520) and the transaction is finished (step 5).
26). As a result of discriminating the deposited banknotes, if there is no returned banknote, the amount of money obtained as a result of the discrimination is displayed on the display 31 (step 521). If the customer confirms the amount of money displayed on the display 31 and avoids it, a confirmation button (not shown) of the input unit 32 is pressed, and this is detected (step 522).

When it is detected that the confirmation button has been pressed, the banknotes are stored in the stackers 16 to 18 (step 523). The pressing plate 5 is moved in the direction opposite to the pressing direction and opened to prepare for the next transaction (step 524). The transaction information is communicated to the host computer, and a request is made to update the ledger file connected to the host computer (step 525).

When the host is contacted, the deposit transaction is terminated (step 526). The withdrawal process will be described. Input unit 32
When it is detected that the withdrawal transaction is selected by the selection button, the withdrawal transaction is started (step 601).

An instruction is displayed on the display 31 to insert the cash card brought by the customer into a card insertion portion (not shown) (step 602). The information recorded on the inserted card is read (step 603). The user is instructed to enter the personal identification number (step 604). Further, it issues an instruction to enter the withdrawal amount (step 6).
05) According to this instruction, the customer inputs the personal identification number and the withdrawal amount from the input unit 32.

The information read from the card and the input unit 32
The information input from the host computer is transmitted to the host computer for inquiry (step 606). At the host, based on the information sent, the bank, branch, account number, PIN,
Inquires about balance etc. and returns the result. If this result is unacceptable, the withdrawal transaction is terminated (step 613).

If the result is good, each stacker 16
The necessary denominations are sent out from Nos. 18 to 18 and conveyed to the ejection unit 1 (step 607). When the dispensed bills are arranged in the dispensing unit 1, the shutter 7 is opened (step 608). The shutter 7 is opened, and an instruction is output to draw out the bills thrown on the display (step 609).

When the detection sensor 2 no longer detects the presence of bills (step 601), the shutter 7 is closed (step 612) and the withdrawal transaction is terminated (step 6).
13). When it is detected that the banknotes cannot be extracted even after the lapse of a predetermined time (step 611), the banknotes in the outlet 1 are taken in and the withdrawal transaction is terminated (step 613).

However, in this case, it is recorded that the bill has not been removed so that no trouble will occur with the customer later. Deposit as described above,
Withdrawal transaction is performed. In order to avoid trouble with the customer, it is necessary to surely have the customer withdraw the banknotes returned to the dispensing section 1 at the time of depositing and the banknotes dispensed to the dispensing section 1 at the time of dispensing.

Therefore, in order to detect the withdrawal of banknotes from the dispensing unit 1, as shown in FIG.
Two stages are provided as 1 and 2-2. Furthermore, the detection sensor 2 is also provided in two stages in the longitudinal direction of the bill 50. The detection sensor 2-1 detects the banknote 50 in a normal state, which is not an abnormal state such as the banknote 50 being folded in a short direction, and the detection sensor 2-1.
Is configured to detect the vicinity of the center of the banknote 50, and a detection sensor provided in the longitudinal direction similarly detects whether the banknote 50 is in an abnormal state such as folded in the longitudinal direction. ..

According to the detection results of these four detection sensors,
Whether the banknote 50 inserted into the dispensing unit 1 is in a normal state, 2
It is detecting whether or not it is folded in half. If the banknote 50 in such an abnormal state is fed into the device from the dispensing unit 1, it may cause a failure. Therefore, it is necessary to immediately stop the dispensing from the dispensing unit 1. However, as shown in FIG. 9, when the banknote 50 that has become wrinkled or folded and is thrown into the bottom of the dispensing unit 1 falls,
The detection sensor 2 cannot detect any more, and the control unit 4 controls the ejection unit 1
It will be detected that the banknotes inside have run out.

This causes trouble with the customer. It is conceivable to provide the detection sensor 2-2 near the bottom, but this cannot detect a banknote that has been caught in the middle, and especially a banknote folded in the lateral direction is caught in the middle. In such a case, the banknotes are present between the detection sensors 2-1 and 2-2, so that the banknotes cannot be detected, causing trouble with the customer.

Although it is possible to provide a large number of detection sensors, it is necessary to increase the number of sensor elements, which increases the power supply and hardware such as a detection circuit for processing the sensor output. Therefore, the software is complicated and the cost of the device is increased. Therefore, the detection operation of the present invention will be described with reference to FIG.

The operation of detecting the bill 50 may be performed at the time points of FIGS. 6 and 7. That is, the shutter 7 is closed by the shutter drive unit 37, and the pressing plate 5
Is moved in the pressing direction by the pressing plate driving unit 35 (step 801), and the feeding roller 3 is rotated by the feeding roller driving unit 33 in the direction opposite to the feeding direction, that is, in the bill withdrawing direction (step). 803).

The rotation of the feeding roller 3 is driven only for a preset time. If the detection sensor 2 does not detect the bill 50 by this operation, it is assumed that all the bills 50 in the dispensing unit 1 have been pulled out or fed into the apparatus, and the process ends normally (step 813). As shown in FIG. 9, when the banknote 50 is present in the ejecting section 1, one end of the banknote 50 is pressed by the pressing plate 5, and the feeding roller 3 is rotated in the pull-out direction. , The banknote 50 that has fallen into the bottom of the dispensing unit 1 is shown in FIG.
As shown in, the detection sensor 2 is ready to detect.

At this time, as shown in FIG. 11, when the detection sensor 2 detects the presence of the bill 50, the pressing plate 5 is driven by the pressing plate driving unit 35 in the opposite direction to the pressing direction.
That is, it moves in the separating direction (step 804). Further, the feeding roller 3 is stopped (step 805). After the shutter 7 is opened by the shutter drive unit 37 (step 806), an instruction is output to the display 31 to remove the bill (step 807).

After the detection sensor 2 detects the presence of the banknote 50 (step 808), if the banknote 50 cannot be removed from the dispensing section 1 even after a predetermined time has passed (step 80).
9) Then, the shutter 7 is closed by the shutter drive unit 37 (step 810), the attendant is notified that an abnormality has occurred, and the abnormality processing for stopping the transaction is performed (step 81).
1).

When the detection sensor 2 detects that the banknote 50 does not exist in the dispensing unit 1 (step 808), the banknote 50 is extracted from the dispensing unit 1 and the shutter 7 is closed and detected. End the operation (step 8)
13). If the pressing plate 5 is moved in the separating direction during this detection operation, the bill 50 may fall back to the bottom of the dispensing unit 1, and therefore the shutter 7 is operated in step 812.
If the above-described detection operation is performed again when closing the, more reliable detection can be performed. The detection operation performed again is 1
It is not limited to times.

In this embodiment, when the shutter 7 is closed,
Although the detection operation is performed, in the deposit process, when the detection sensor 2 no longer detects the banknotes in the dispensing unit 1 after the feeding operation (step 508) is performed, the detection operation of the present invention is performed. By performing, by the feeding unit 3,
It is possible to detect banknotes that could not be delivered. Further, in this embodiment, when the detection sensor 2 runs out of banknotes in the ejection unit 1, the feeding roller 3 and the pressing plate 5 are started to be driven. It goes without saying that it is also possible to detect that the sheets are no longer present, operate the shutter 7, and then to operate the delivery roller 3 and the pressing plate 5 after detecting the operation of the shutter 7. ..

[0041]

As in the present invention, when the bills in the dispensing section are no longer detected, the pressing plate is folded in the pressing direction and the feeding section is rotated in the pulling direction. Alternatively, it is possible to make a bill that has fallen into the bottom of the throw-out portion detectable because of a wrinkle or the like, so that the presence of the bill in the throw-out portion can be reliably detected.

Further, since the shutter closing operation is performed in parallel, the transaction time including the detecting operation can be shortened. Therefore, the service to the customer can be improved. Further, since the present invention can be carried out by slightly changing the control because the existing hardware is used, it is possible to provide a reliable device without increasing the cost of the device.
