Is formed with a through hole 10B. The hand detection sensor indicated by the reference numeral 40 is a sensor for detecting the hand of an operator who takes out the banknotes C aligned and stacked at the alignment stacking position in the banknote dispensing unit 10. Since a hand is often inserted and removed from the front side of the banknote dispenser, as shown in FIG. 3, a light projector and a light receiver are arranged in the horizontal direction on the front side of the banknote dispensing apparatus 1 from the aligned accumulation position.

Further, the residual detection sensor denoted by reference numeral 50 has a light emitting device 51 and a light receiving device 52 arranged on the end surface of the shutter 21, that is, the lower surface on the side of the first conveyor belt 15, and a bottom portion of the bill dispensing portion 10. The reflecting member 22 is arranged on the upper surface of the 10A, and the light projecting device 51, the light receiving device 52, and the reflecting member 22 are arranged so that the light emitted from the light projecting device 51 is reflected by the reflecting member 22 and reaches the light receiving device 52. And configure. In this case, the light emitter 51 and the light receiver 5
2 are arranged adjacent to each other, the reflecting member 22 is positioned almost directly below the light projector 51 and the light
Is formed in a longitudinal shape in the direction in which the shutter 21 moves, so that even if the light projector 51 and the light receiver 52 move with the opening and closing operation of the shutter 21, the residual detection sensor 50 can be constituted by one reflection member 22. Also, from this, the light emitter 51 and the light receiver 5
Obviously, it is not necessary to dispose the reflectors 2 adjacent to each other, and it is sufficient to arrange them on the lower surface of the target shutter with the reflection member 22 interposed therebetween. Furthermore, the residual detection sensor 50 including the light projector 51, the light receiver 52, and the reflection member 22 has one
It is clear that a plurality of sets may be displaced in a direction orthogonal to the moving direction of the shutter 21 without being limited to the sets, and the reflecting member 22 in that case is not affected by the moving mechanism of the bill press 19. , Bottom portion 10A of banknote dispensing section 10
It is clear that the upper surface can be formed by a single member that covers almost the front surface.

FIG. 5 is a block diagram 90 for explaining the shutter control means of the bill dispensing section 10. As shown in FIG. That is,
The bill detection sensor 30 that detects whether the bill C to be dispensed exists between the first conveyor belt 15 and the bill press 19 in the bill dispensing unit 10, and the first of the bill dispensing unit 10. A hand detection sensor 40 for detecting whether or not a hand for extracting the bill C held between the conveyor belt 15 and the bill press 19 is in the bill dispensing section 10, and whether or not the shutter 21 is in a closed state. A closed state detecting sensor 70 for detecting, a maximum open state detecting sensor 80 for detecting whether or not the shutter 21 is in a maximum open state, a residual detecting sensor 50 for detecting whether there is a residual bill in the bill dispensing section 10. When the drive motor 64 that opens and closes the shutter 21 and the residual detection sensor 50 detects that there is a residual bill in the bill dispensing section 10, an alarm sound, an alarm display, and the like are performed.
ROM 53 for storing an operation program and the like of the banknote dispensing apparatus 1 shown in a flowchart of FIG. 6, which will be described later. Information of various sensors is temporarily stored in accordance with the operation program of the ROM 92. RAM 9 to do
1. A CPU 93 that controls these components as a whole is connected to each other.

The operation of the shutter control means of the bill dispensing section 10 of the present invention will be described below with reference to the flowchart of FIG. Step 1 (hereinafter, simply referred to as S1): As described above, when the shutter 21 is in the closed state, the set denomination and the number of banknotes C are transferred from the inside of the apparatus to the first transport belt 15 and the bill press. The bill C is sent to the alignment and accumulation position between 19 and the presence of the bill C is detected by the bill detection sensor 30. S2: When the banknotes C of the set denomination and the number of banknotes C have been aligned and accumulated, the drive motor 64 is driven to rotate forward and the opening operation of the shutter 21 starts. S3: Shutter 2 by forward drive of drive motor 64
1 is continued until the rear end of the shutter 21 is detected by the maximum open state detection sensor 80. When the rear end of the shutter 21 is detected by the maximum open state detection sensor 80, the shutter 21 is released. Assuming that the motor is fully opened (S4), the forward rotation of the drive motor 64 is terminated.

S5: Subsequently, the detection states of the bill detecting sensor 30 and the hand detecting sensor 40 are examined. When the bill detecting sensor 30 does not detect the bill C and the hand detecting sensor 40 does not detect the hand, the bill is detected. It is determined that the banknote C does not remain in the dispensing section 10 and that the take-out person has pulled out of the banknote dispensing section 10, and the process proceeds to the next step 6. When the bill detection sensor 30 is detecting the bill C or when the hand detection sensor 40 is detecting the hand, it is determined that the work of extracting the bill C is not completed, and the process stands by at this step. S6: Wait for a predetermined time, for example, about 2 to 3 seconds, to elapse after the bill C is extracted from the bill dispensing section 10, and in the next step 7, drive the motor 64 in reverse. Then, the closing operation of the shutter 21 is started.

S8: The closing operation of the shutter 21 by the reverse drive of the drive motor 64 detects the rear end of the shutter 21 by the closed state detecting sensor 70 unless the residual detecting sensor 50 detects the remaining bill C '( S9) is continued until the rear end of the shutter 21 is closed state detection sensor 7
0, the shutter 21 is closed (S1
0), the reverse drive of the drive motor 64 ends. On the other hand, during the closing operation of the shutter 21 by the reverse drive of the drive motor 64, when the residual detection sensor 50 detects the residual banknote C ', that is, the banknote falls down and the banknote detection sensor 30 and the hand detection sensor 40 When there is a banknote C ′ that is not detected in any of the cases, the light emitter 51 on the lower surface of the shutter 21 is closed while the shutter 21 is closing.
Is reflected by the reflecting member 22, and as long as the reflected light is incident on the light receiver 52, it is determined that there is no remaining bill C '. However, the shutter 21 is further closed and the light projector When the irradiation light from 51 is blocked by the remaining bills, the reflected light does not enter the light receiver 52, so that it is determined that there is a remaining bill C '.

S11: At this time, if it is determined that there is a residual bill C ', the alarm 53 is immediately activated. S12: Further, the closing operation of the shutter 21 by the reverse drive of the drive motor 64 up to this point is interrupted, and instead, the opening operation of the shutter 21 by the forward drive of the drive motor 64 is started. The opening operation at this time is
Since it is configured to return to step 3, the process is continued until the rear end of the shutter 21 is detected by the maximum open state detection sensor 80, and the rear end of the shutter 21 is detected by the maximum open state detection sensor 80. And the shutter 21
Is fully opened (S4), the forward rotation of the drive motor 64 is terminated, and the same operation is continued thereafter.

According to this flowchart, when the residual bill C 'is detected by the residual detecting sensor 50, the shutter 21 is opened to the maximum, so that the bill dispensing section 10 It is possible to very easily take out the remaining bills C ′ remaining in the paper money.

The control is not limited to the control shown in the flowchart, but may be performed as follows. Modification Example 1 When the residual bill C 'is detected by the residual detection sensor 50, the closing operation of the shutter 21 can be stopped and the shutter 21 can be controlled so as to remain in place. In this case, the shutter 21 after the removal of the residual bill C '
Can be minimized until the end of the closing operation. Modified Example 2: When the residual bill C 'is detected by the residual detection sensor 50, the shutter 21 can be controlled to be opened for a predetermined time after the closing operation of the shutter 21 is stopped. In this case, since the shutter 21 does not always open to the maximum open state, the shutter 21 after removing the remaining banknotes C ′ is more open than when the shutter 21 opens to the maximum open state.
Can be shortened and the removal of the remaining banknote C ′ from the banknote dispensing unit 10 is easier than when the shutter 21 remains at the position where the remaining banknote C ′ is detected. Become.

Modified Example 3: The alarm 53 is replaced with the remaining bill C '.
When the shutter 21 is opened to the maximum open state or when the shutter 21 is opened for a predetermined time, the drive motor 64 rotates forward. Driven by shutter 21
Is released, the residual bill C ′ is
The remaining bill C 'is detected by the residual detection sensor 50, and then the shutter 2
1 can be opened, and the alarm 53 can be maintained in the operating state until immediately before the closing operation is started again. Thereby, even if the shutter 21 is opened immediately after the detection of the residual banknote C ', it can be easily confirmed that the residual banknote C' exists.

[0025]

According to the present invention, since the residual detecting means has an optical axis in a substantially vertical direction between the lower surface of the shutter and the upper surface of the bottom of the bill dispensing section, when the shutter is about to be closed. Since the optical axis also moves in accordance with the movement of the shutter, even a bill lying down can be reliably detected, and furthermore, by this residual detecting means,
When a remaining bill is detected in the bill dispensing unit, the shutter closing operation can be interrupted by the shutter control means, so that the remaining bill can be reliably taken out when the shutter closing operation is interrupted. .
