[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a shutter mechanism of an automatic transaction device according to the present invention, which is used to insert or take out banknotes 17, etc., which are transaction objects, on the operation surface of an automatic transaction device 2 such as a deposit/withdrawal machine. An operation chamber 3 is formed. A shutter 1 is provided at the opening of the operation chamber 3 and is slidably moved (in the left-right direction in the figure) by a shutter opening/closing mechanism.

Banknotes 17 used for depositing and withdrawing money, for example, are placed on the bottom surface 15 and front surface 16 of the operation chamber 3 in alignment.

Next, the shutter mechanism for opening and closing the shutter 1 of the deposit/withdrawal port will be explained with reference to FIG. 2.

In this shutter mechanism, one or both sides of the shutter 1 are sandwiched between a drive roller 4 and a pinch roller 5 and pressed together, and the drive roller 4 and the DC for driving the shutter are connected to each other.
By connecting the motor 8 with the gear 6.7, D
The shutter 1 is opened and closed by the driving force of the C motor 8. Also,
As shown in the figure, a shutter position detector 12, 13 for detecting the open/closed state of the shutter l and a lock detector 14 for detecting that the shutter lock lever 9 is locked are located on the side surface of the shutter mechanism. etc. When the shutter 1 is operating and when the shutter 1 is stopped, the shutter 1
In order to eliminate left and right play, one side of the shutter 1 is bent into an L-shape, and the L-shaped bent part is inserted into the groove of the guide 11, so that the shutter 1 can be opened and closed along this groove. be.

Next, the operation of this embodiment will be explained.

Now, when a banknote 18 or the like is transacted in this automatic transaction device, the DC solenoid 10 unlocks the shutter lock lever 9 by operating an operation panel (not shown), and the lock detector 14 unlocks the shutter lock lever 9. When the release is detected, the DC motor 8 moves in the direction of arrow A in FIG.
The rotation is transmitted to the drive roller 4 via the gear 6.7.

Then, the shutter 1 is sandwiched between the drive roller 4 and the pinch roller 5, and the shutter 1 is smoothly slid in the direction of arrow C in the figure along the guide 11 without any lateral play by the driving force of the DC motor 8.

At this time, the shutter 1 is moved in the direction of the arrow C described above until the shutter 1 is detected by the shutter position detector 12. That is, when the rear end of the shutter 1 comes to the position set by the shutter position detector 12, the shutter 1 becomes fully open and stops.

In this way, when a normal transaction operation such as inserting banknotes 17 etc. into the operation chamber 3 or trading is performed, the shutter 1 is closed after a predetermined period of time has elapsed. In the closing operation, the DC motor 8 rotates in the direction of the arrow and transmits rotation to the drive roller 4 via the gear 6.7. This drive roller 4
By pinching the shutter 1 with the pinch roller 5, the driving force of the DC motor 8 slides the shutter 1 along the guide 11 in the direction of the arrow in FIG. 2, opposite to the opening operation described above. When the shutter 1 is detected by the shutter position detector 13 and moved to the position, the shutter 1 is locked by the lock lever 9. When the lock detector 14 detects that the shutter 1 is locked by the lock lever 9, the shutter 1 stops with the operation chamber 3 closed. In this way, shutter 1
D for opening/closing drive unless the lock detector 14 detects that it is completely closed and locked by the lock lever 9.
A stop command for the C motor 8 is not output. Therefore, when the shutter 1 is completely closed and stopped, the shutter 1 is locked by the lock lever 9, and it is difficult to open it from the outside. Furthermore, even if the shutter 1 is forcibly opened, the shutter position detector 13 and lock detector 14 can detect that the shutter 1 has been opened, and can tell if there is an abnormality in the shutter 1. .

In addition, as shown in FIG. 1, the user who is performing the transaction operation may continue to insert his or her finger 18 into the operation room 3 even after the predetermined period of time has elapsed, or if an object is placed on the shutter l. When a shutter close command is issued and the shutter 1 moves toward closing in the direction indicated by the arrow, the operation of the shutter 1 is blocked by the finger 18, etc., and the shutter position is not detected within the specified time. device 13 and lock detector 14
Assume that it is not detected that the shutter 1 is completely closed. In this case, move the shutter 1 once in the opening direction (arrow C
direction), then perform the closing operation again to close shutter 1.
The opening/closing drive D
The C motor 8 is controlled to reduce mechanical operational errors.

FIG. 3 shows a block configuration of a shutter M control device of an automatic transaction device according to the present invention.

In the case of a shutter opening operation, the shutter opening/closing command 19 selects the shutter opening operation and outputs a signal indicating the shutter opening to the control means 20. The control means 20 controls the shutter lock mechanism 22 and the shutter drive means 21 to open the shutter 1, and in the case of a shutter closing operation, selects and controls the shutter closing operation by a shutter opening/closing command 19. Then, the control means 20 controls the shutter drive means 21 to perform a shutter opening operation, and the shutter drive means 2 continues to operate until the shutter 1 is locked by the shutter lock mechanism 22.
Control 1. However, as described above, if the shutter closing operation is not completed within the specified time, the control means 20 is configured to control the shutter driving means 21 so as to repeat the opening and closing operation of the shutter 1 a plurality of times.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

(]) When the shutter is closed, a locking mechanism is provided to prevent it from being opened from the outside, and even if the shutter is opened, it is designed to detect abnormalities in the shutter, making it a highly security-resistant shutter mechanism. can.

(2) The drive source for the shutter mechanism is a C motor, which is easy to control, and its driving force is transmitted to the roller, and the roller's clamping force moves the shutter along one guide, reducing the number of parts, making it compact and inexpensive.
