(Problems from a design point of view)
In recent ATMs, the design is also important, and in order not to give an intimidating feeling to the operator as much as possible, as shown in FIG. 10, the casings 101a and 101b of the operation surface are not horizontal but inclined at an appropriate angle, It is desirable to make the shutter 1 and the casings 101a and 101b flat so that the joints between the casings 101a and 101b and the shutter are not noticeable.

  However, in the conventional ATM shutter mechanism, as in the shutter mechanism of FIGS. 7 and 8, in order to obtain a simple shutter mechanism, the operation surface is leveled, and accordingly, the shutter is leveled, or the casings 101a and 101b. It was necessary to lower the shutter surface.

  Further, in the conventional ATM shutter mechanism shown in FIGS. 7 and 8, even if the operation surface (housing) is inclined and the shutter is inclined as shown in FIG. 10, the shutter 1 is pulled into the ATM 200. In addition, since it is drawn in the direction of the arrow D, it is not drawn into the region B but drawn into the region A. For this reason, the shutter mechanism interferes with the bankbook unit behind the bankbook slot and the card unit behind the card slot, and the ATM cannot be downsized.

(Problems with locking mechanism)
The conventional ATM shutter mechanism shown in FIG. 7 can be locked even if an external force F is applied by inserting the link engaging portion 51 of the link mechanism 3 into the retracting portion 2a of the guide rail 2. When there is vibration or the like, the link coupling portion 51 is lowered and the lock may be released.

  In order to prevent this, a lock portion 6 for holding the lock is newly provided as in the conventional ATM shutter mechanism of FIG. 9, or the diameter of the drive portion 4 is increased so as not to cause backlash. Thus, it is necessary to lock completely, but this method cannot reduce the cost by reducing the size of the ATM or reducing the number of members.

(Problems for theft prevention)
Furthermore, in recent years, crimes related to ATMs are increasing, and there are also cases in which the shutter 1 is destroyed and banknotes are taken out.

  However, in the conventional ATM shutter mechanism shown in FIGS. 7 to 9, it is detected that the shutter state is not directly detected but the lock applied to the link mechanism or the power transmission unit is released. Therefore, since the shutter breakage is detected, the shutter breakage cannot be reliably detected.

  The present invention employs the following configuration in order to solve the above-described problems. That is, a shutter provided obliquely, a guide rail disposed at a predetermined angle with respect to the shutter, one end connected to the shutter, the other end connected to the driving means, and the end on the side connected to the shutter Is provided with a link mechanism that moves the shutter while being guided by the guide rail, and a first sensor that detects a position where the shutter is closed and fixed, and a shutter fixing position is determined by the first sensor, and the guide The link mechanism was fixed by the rail and the driving means to fix the shutter.

  According to the shutter mechanism of the automatic transaction apparatus of the present invention, since the guide rail for guiding the shutter is provided, the shutter is opened and closed even when the operation surface is inclined and the housing and the shutter are flat. It can be locked completely in the closed state.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element which is common in drawing.

  In the ATM shutter mechanism of the first embodiment, a shutter such as a bill insertion slot is provided on the substantially same surface as the oblique operation surface without providing a new lock portion, and the shutter can be opened and closed and completely locked with a simple configuration. It is something that can be done.

(Constitution)
First, the external structure of the automatic transaction apparatus (ATM) of Example 1 is demonstrated. The ATM 200 is an operation composed of an operation button, a touch panel for inputting an account number, etc. in front of the customer (hereinafter referred to as “device front side” and the rear side as “device rear side”). The unit 205, a bill insertion slot 201 for inserting or removing banknotes and coins, and a coin insertion slot 202 are covered by the shutter 1 on the rear side of the apparatus, and are arranged obliquely at an appropriate angle so that the customer can easily operate. .

  In addition, a passbook slot 203 and a card slot 204 for inserting or returning a passbook or card are arranged on the rear side of the apparatus. That is, a passbook unit and a card unit (not shown) are arranged in the ATM device 200 at the positions of the passbook slot 203 and the card slot 204.

  Next, the ATM shutter mechanism of Embodiment 1 will be described with reference to FIG. The shutter mechanism according to the first embodiment includes a shutter 1 that covers a coin and banknote slot described with reference to the external view of the ATM 200 in FIG. 1 and a retracting portion 2 a that is disposed on the rear side of the apparatus to guide the movement of the shutter 1. A guide rail 22 provided on the front side of the apparatus, a drive belt 5 bridged by rollers 5a and 5b, a drive unit 4 for driving the drive belt 5 through the roller 5a, and a shutter. 1 and a drive mechanism 5, a link mechanism 3, a shutter open sensor 23 that detects the open state of the shutter 1, and a shutter lock sensor 24 that detects lock.

  The guide rails 2 and 22 may be curved instead of a straight line having a groove of the same width, and if it can be guided, it is not a rail shape having a groove, but a slider type shape that slides a single shaft, etc. Such a structure may be used.

  Further, as long as it is a means capable of moving the link mechanism 3 instead of the moving means by the drive belt 5, it may be a moving means using a lead screw that includes a rack and a pinion.

  The shutter opening sensor 23 and the shutter lock sensor 24 only need to be able to detect the position of the lower connecting portion 13 of the link mechanism, and may be a reflective sensor. The connecting portion 13 is provided with a protrusion or the like. A transmission type sensor may be used.

(Operation)
With the above configuration, the ATM shutter mechanism of the first embodiment operates as follows. This operation will be described below with reference to FIG. 2 described above, FIG. 3 showing a state in which the shutter 1 starts to open, and FIG. 4 showing a state in which the shutter 1 is opened.

  First, since the shutter lock sensor 24 is detected in the shutter closed state of FIG. 2, the control unit (not shown) checks the detection signal of this sensor, rotates the drive unit 4 in the direction of arrow A, and passes through the roller 5a. The drive belt 5 is moved in the direction of arrow A ′.

  Then, the lower connection portion 13 of the link mechanism 3 connected to the drive belt 5 moves in the direction of the arrow A ′ together with the drive belt 5, and then the upper connection portion 12 of the link mechanism 3 is guided by the guide rail 2 to the lower side. The shutter 1 starts to move along with the movement, and the state shown in FIG. 3 is obtained. At this time, the end portion (right side in the drawing) of the shutter 1 on the front side of the apparatus moves while being guided by the guide rail 22 on the front side of the apparatus.

  When the drive unit 4 is further rotated in the direction of arrow A and the drive belt 5 is moved in the direction of arrow A ′, the lower connecting portion 13 of the link mechanism 3 crosses the shutter opening sensor 23. 1 is determined to be in a fully open state, the drive of the drive unit 4 is stopped, and the state of FIG. 4 is obtained.

  On the other hand, when the shutter 1 is closed from the shutter open state of FIG. 4, when the shutter 1 is confirmed by the shutter open sensor 23 and the drive unit 4 is rotated in the direction of arrow B, the drive belt 5 is connected via the roller 5a. Starts to move in the direction of the arrow B ′, and the lower connecting portion 13 of the link mechanism 3 similarly starts to move in the direction of the arrow B ′. As a result, the shutter 1 moves to the state shown in FIG. The connecting portion 12 is guided by the guide rail 2 and moved upward, and further driven until the lower connecting portion 13 of the link mechanism 3 crosses the shutter lock sensor 24, and stops in the state of FIG.

  In order to completely lock the shutter 1 with the retracting portion 2a, the shutter lock sensor 24 is preferably provided slightly on the front side (right side in the drawing) of the retracting portion 2a.

  Even in the shutter closing operation described above, the end portion (right side in the figure) of the shutter 1 on the front side of the apparatus is guided and moved by the guide rail 22 on the front side of the apparatus as in the case of the operation of opening the shutter. is there.

(Effect of Example 1)
As described above in detail, according to the ATM shutter mechanism of the first embodiment, the guide rail 2 for guiding the shutter 1 is provided with the retracting portion 2a. Even with a flat structure, the shutter can be opened and closed with a simple configuration and can be completely locked in the closed state.

  The ATM shutter mechanism according to the second embodiment is provided with a stopper that suppresses the movement of the lower link portion of the link mechanism in the closing direction at a position where the link mechanism in the locked state does not come off the retracting portion due to external force. It is.

(Constitution)
As shown in FIG. 5, the ATM shutter mechanism according to the second embodiment is configured such that the link mechanism 3 has a predetermined angle (solid line) and the stopper 14 that suppresses the movement of the lower connecting portion 13 of the link mechanism 3 in the closing direction. It is provided at such a position. Other configurations are the same as the configurations of the first embodiment, and detailed description thereof is omitted for the sake of brevity.

(Operation)
With the above configuration, the ATM shutter mechanism of the second embodiment operates as follows. Of the operations of the ATM shutter mechanism of the second embodiment, the operations for opening and closing the shutter 1 are the same as those described with reference to FIGS. 2 to 4 in the description of the operation of the first embodiment. Therefore, the description is omitted for simplification.

  In the ATM shutter mechanism of the first embodiment, in the closing operation, the lock is detected by the shutter lock sensor 24 and stopped, but if it goes too far, the upper connecting portion 12 of the link mechanism 3 of the retracting portion 2a starts to lower again, and the shutter 1 However, since the stopper 14 is provided at the position shown in FIG. 5 in the ATM shutter mechanism of the second embodiment, the overshoot can be suppressed and stopped at a reliable position.

  When the external force in the direction of the arrow F1 is applied in the locked state and the movement is suppressed, the movement is suppressed by the retracting portion 2a of the guide rail 2, so that the shutter 1 is not opened.

  Also, when an external force in the direction of the vertical arrow F2 is applied to the shutter 1, if the angle θ1 between the rear side of the link mechanism 3 (left side in the figure) and the link mechanism 3 is 90 degrees or less, the link mechanism 3 Since the force to the lower connecting portion 13 is in the direction of the arrow F3, the stopper 14 can lock the force.

  Further, when an external force is generated in the direction of gravity due to vibration or the like instead of an external force to the shutter, the lower side of the link mechanism 3 must be set so that the gravity direction of the link mechanism 3 and the angle θ2 of the link mechanism 3 are not more than 0 degrees. Since the external force applied to the connecting portion 13 is opposite to the direction of the arrow F3, it is preferable to provide the stopper 14 so that the angle θ2 is 0 degree or more.

  The above relationship is the same even if the angle θ0 of the operation surface changes.

(Effect of Example 2)
As described in detail above, according to the ATM shutter mechanism of the second embodiment, the stopper 14 that suppresses the movement of the lower connecting portion of the link mechanism is provided. The shutter 1 can be completely locked even if vibration in the direction of gravity is applied.

  In the ATM shutter mechanism of the third embodiment, a shutter close sensor is provided in the vicinity of the end of the shutter at the closed position so that the destruction of the shutter can be directly detected.

(Constitution)
The ATM shutter mechanism of the third embodiment is the same as that of the first and second embodiments except that a shutter closing sensor 25 is provided on the rear side (left side in the figure) of the shutter 1 as shown in FIG. Therefore, for simplification, description of the same configuration is omitted.

  The shutter closing sensor 25 may be a reflective sensor or an end of the shutter 1 as long as it can detect whether the end of the shutter 1 is positioned in the vicinity of the sensor or at a certain angle. An appropriate protrusion or the like may be provided on the sensor, and a transmission type sensor may detect whether the protrusion has crossed the sensor.

(Operation)
With the above configuration, the ATM shutter mechanism of the third embodiment operates as follows. The operation of the ATM shutter mechanism of the first and second embodiments is different from the operation of detecting the closed state of the shutter 1 and the operation of detecting the shutter 1 being destroyed in the closed state.

  Other operations are the same as the operations described with reference to FIGS. 2 to 4 in the description of the operation of the first or second embodiment, and thus the description thereof is omitted for simplification.

  In the ATM shutter mechanism according to the third embodiment, a state in which the shutter 1 is closed is detected by the shutter closing sensor 25 in the operation of closing the shutter 1. In this way, it can be directly detected whether the shutter 1 is securely closed. Of course, the shutter lock sensor 24 may be provided as in the first and second embodiments to detect and lock the shutter.

  Then, before starting the operation of opening the shutter 1 in a state where the shutter 1 is once closed (broken line in FIG. 6), the shutter 1 is destroyed, for example, like the shutter 1 ′ in FIG. When it is detected that the end of the shutter has been detached, it is determined that the shutter 1 has been destroyed, and the ATM staff is notified accordingly.

  In the above description, the sensor for detecting the destruction of the shutter 1 is described as being provided on the rear side of the apparatus of the shutter 1, but may be provided on the front side of the apparatus or both.

(Effect of Example 3)
As described in detail above, according to the ATM shutter mechanism of the third embodiment, since the shutter closing sensor is provided at the end of the shutter 1, in addition to the effects of the first or second embodiment, the shutter 1 is destroyed. Can be reliably detected.

  As described above, the present invention can be widely used in medium processing apparatuses such as banknote depositing and dispensing machines, bond collection and issue machines, and ticket collection and issue machines that handle paper-like media and fixed-shaped media.
