The operation pin 34 is coupled to the operation pin 52 of the door frame 40 to be described later, the spring (with respect to the main body 10 so that the operation pin 52 rotates in a direction away from the locking groove 34b) 36) It is hard.

The door frame 40 is provided on the inner side of the side wall 12, the lower end is fixed to the rotating shaft 42 penetrating the body 10 in the transverse direction, the door for opening and closing the banknote opening 14 in the upper end ( 44 is integrally formed. Then, the rotating shaft 42 extends to the outside of the side wall, the lower end of the door opening lever 50 is fixed on the extension portion. In the center of the door opening lever 50, the operating pin 52 is coupled to the operating hole 34 is configured to rotate about the rotary shaft 42 by interlocking with the driving lever 30, the rotary shaft 42 By rotating the door frame 40 through the) is composed of opening and closing soil bank entrance. In addition, the door open lever 50 is always supported by a spring 54 relative to the main body 10 so that the door 44 rotates in the direction of closing the banknote entrance.

The lock lever 60 is rotatably coupled to the side wall 12 with the pin 62 at the top of the drive lever 30, and the actuating pin 52 when the drive lever 30 is in the raised position at the bottom thereof. The stopper 66 which restricts rotation in the direction deviating from this locking groove 34b is comprised integrally.

The force to limit the rotation of the lever 30 will be provided. In addition, the lock lever 60 is rotated by the force of the spring 69 when the drive lever 30 is in the lowered position. At this time, the stopper pin 64a restricting the rotation of the lock lever 60 at a predetermined position on the side wall. ) Is provided. According to the present invention, the lock lever 60 rotates artificially to allow the drive lever 30 to rotate manually, thereby opening and closing the door 44 by a handle 68 to facilitate gripping during manual operation. It is constructed integrally on the top. In addition, it is preferable to further provide a stopper pin 64b on the side wall 12 which limits the further rotation after the rotation angle of the lock lever 60 is sufficiently rotated to open the door 44 during manual operation. This means that the lock lever 60 is configured to be limitedly rotatable within a certain angle range in the clockwise and counterclockwise directions with respect to the main body 10.

The switch means is interfered with the lower end of the door opening lever 50, the door open detection switch 70 for detecting the completion of the opening of the door 44, the door opening lever 50 interferes with the side of the door 44 The door closing detection switch 72 for detecting the completion of closing, and the drive motor detection switch 74 for applying a control signal to the drive motor 20 when the drive pin 26 is in a specific position every rotation of the drive motor 20. The signal sensed by each of the switches is applied to the main controller to be comprehensively controlled.

Looking at the operating state of the door opening and closing device of the banknote deposit and withdrawal machine according to the present invention having such a configuration as follows.

First, as shown in FIG. 1, in the closed state of the door 44, the driving pin 26 'off' the motor detection switch 74 in the raised position to keep the motor stopped. In this case, the driving lever 30 ), The driving lever 30 rotates clockwise in the drawing due to the rotational force of the door open lever 50 by the spring 54 and the pressing force of the stopper 66 by the spring 69 force. The operation pin 52 is in the locking groove 34b. At this time, the door driving lever 30 maintains a state in which the door closing detection switch 72 is pressed. Therefore, when the door is forcibly opened in such a state, the door open lever 50 interlocking with the door frame 40 has a force to rotate counterclockwise. However, in the door driving lever 30, the operation pin 52 is caught in the locking groove 34b, and the driving lever 30 is limited to the rotation by the lock lever 60, as well as the motor 20 is stopped. Since the opening of the door 44 is not made. More specifically, the rotational force of the door driving lever 30 acts in the normal direction of the circle centering on the rotating shaft 42, and this direction acts in a direction similar to the longitudinal direction of the driving lever 30, so that it is caught. The component is caught by the groove 34b, and moreover, the component force acting in the direction to rotate the drive lever 30 by the normal force supports the spring 54 and the lock lever 60 supporting the door open lever 50. Since it is overpowered by the force of the spring (69) will not be able to achieve the opening of the door (44).

On the other hand, when the door 44 is opened, as shown in FIG. 2, when the driving motor 20 is operated by the driving signal, the driving motor 20 starts to rotate counterclockwise in the drawing. Since the driving pin 26 fixed to 24 is moved downward in a circular motion, the driving lever 30 coupled thereto is moved downward. Therefore, the operation pin 52 which is caught in the locking groove 34b is moved to the lower side. In this case, the driving lever 30 moves in a direction orthogonal to the pressing direction of the lock lever 60, that is, in the vertical direction. Interference with (60) does not occur much. In addition, the actuating pin 52 is separated from the locking groove 34b as the driving lever 30 gradually descends and is positioned at the upper end of the long hole 34a, and is continuously accompanied by the lowering of the driving lever 30 to rotate the rotation shaft 42. Descending in a circle around the circle. Therefore, the door open lever 50 is rotated while tensioning the spring 54, and the door frame 40 and the door 44, which are fixed to the rotary shaft 42 and the rotary shaft, rotate counterclockwise in the drawing, and insert the banknote. (14) is opened. The driving lever 30 turns on the door open detection switch 70 at a time when a certain amount of rotation is achieved, and the driving motor 20 is stopped by this signal. Preferably, the stop position of the main drive motor 20 is set to a 180 ° rotational position.

The lock lever 60 is rotated by the spring 69 as the drive lever 30 is lowered, at which time the rotation of the lock lever 60 is limited in a predetermined position by the stopper pin 64a. When the driving motor 20 is rotated counterclockwise again when the door closing signal is applied, the door opening lever 50 is rotated clockwise by the elastic restoring force of the spring 54 so that the door 44 is closed. To rotate. The driving lever 30 which is raised by the motor driving is rotated in the direction in which the locking groove 34b receives the operation pin 52 again because the upper end is interfered by the stopper 66 of the lock lever 60. When the door is closed, the door closing detection switch 72 detects the completion of the closing of the door 44, and the driving motor detection switch 74 is operated by the driving pin 26 to drive the motor 20. By closing the door 44, the closing operation of the door 44 is completed.

Meanwhile, as shown in FIG. 3, when the user's hand or bill is caught by the door 44 due to carelessness of the user during the closing operation of the door 44, the door 44 may not rotate. At this time, since the driving pin 52 is guided to the long hole 34a to allow the driving lever 30 to rise, the driving lever 30 is continuously driven without being overloaded. In addition, the driving motor detection switch 74 is operated by the driving pin 26 to stop the driving motor 20.

In addition, when the interference force acting on the door 44 in the above state, that is, the hand or banknotes caught on the door 44 is removed, the door opening lever 50 is rotated by the force of the springs 54 and 69. Also returned to the state as shown in Figure 1 to maintain the closed and locked state of the door.

As described above, the door opening and closing device of the banknote entry / exit machine according to the present invention is a drive motor fixed to the inlet body to provide a driving force for opening and closing the door, a drive lever for raising and lowering in a substantially vertical direction by the drive motor, and driving A door frame that interlocks with a lever and rotates an actual door to perform an opening and closing action, and detects an open and closed position of a door and a lock lever that interferes with the driving lever and restricts an artificial opening of the door frame, and a rotational position of a motor. It is possible to simplify the structure by providing a locking means to maintain the closed state as well as the door opening and closing by a single motor with a switch means, as well as when the door closing operation by the interference when the door is closed is restricted. It has the effect of minimizing the failure rate by preventing the overload of the drive motor.
