The present invention relates to a banknote opening and closing device of a vending machine, and more particularly to a switchgear that can automatically open and close the banknote opening.

As shown in FIG. 1, a vending machine generally includes an outer body including a main body 10 in which merchandise and various parts are stored, and a door 20 that opens and closes the main body 10. On the front of the door 20, a display room 30 for displaying a product to be sold, a plurality of selection buttons 40 for selecting a product displayed in the display room 30, and a bill input 50 to which a product price is input. And a coin inlet 60, a return inlet 70 through which defective coins or change is returned, and a product outlet 80 through which the selected product is ejected.

On the other hand, as shown in Figure 2, the banknote 50 is formed inside the opening 22 formed by recessing the front panel 21 of the door 20, the door 20 or the vending machine main body 10 It communicates with the inlet 91 of the banknote identifier 90 installed inside. On the other hand, in order to prevent dust or direct sunlight from entering the inside of the banknote identifier 90, the cover 51 for opening and closing the banknote opening 50 is rotatably installed on the front panel 21 of the door 20.

Since the upper end of the cover 51 is rotatably supported by the front panel 21 of the door 20, the cover 51 is always in a position to close the banknote input port 50 due to its own weight. Therefore, when the user inserts the bill P, the user inserts the bill P into the bill input slot 50 with the other hand while the cover 51 is lifted with one hand. When the cover 51 is released from the cover 51, the cover 51 automatically returns to the closed position.

By the way, according to the conventional banknote opening and closing device as described above, in order to put the banknote into the banknote inlet 50, both hands must be used, which is inconvenient. In addition, since the cover 51 is returned to the closed position in a free-falling manner, the banknote opening 50 cannot be completely sealed, and the cover 51 is easily opened by the wind. By flowing in, there is a problem that the banknote identification ability of the banknote identifier 90 is lowered.

The present invention has been made in order to solve the above problems, the cover is automatically opened and closed depending on the proximity of the bill to the banknote opening, banknotes can be put in one hand and can improve the sealing of the banknote opening The purpose is to provide an inlet opening and closing device.

An object of the present invention as described above, the cover is installed rotatably in front of the banknote opening and the cover, opening and closing the banknote opening, the proximity sensor is installed adjacent to the banknote opening and detects the proximity of the banknote, and the proximity sensor It is achieved by providing a banknote opening and closing device including a drive means for rotating the cover in accordance with the detection result.

Here, the drive means is composed of a solenoid for pressing the cover in the opening direction, and a spring for biasing the cover in the closing direction.

Meanwhile, a lever in contact with the driving shaft of the solenoid is extended behind the hinge shaft of the cover, and one end of the spring is coupled to the lever.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. However, the same reference numerals are used for the same components as those of the prior art, and detailed description thereof will be omitted.

As illustrated in FIG. 3, the banknote opening and closing device according to the present invention is rotatably installed inside the opening 22 formed by recessing the front panel 21 of the vending machine door 20 (see FIG. 1). The cover 51 which opens and closes the inlet 50, the lever 53 extending rearward of the hinge shaft 52 of the cover 51, and the cover 51 by pressing the lever 53 open the cover 51. Direction, that is, the solenoid 54 which rotates to the open position, the spring 55 which returns the lid 51 to the closed position, and the proximity provided on the lower surface of the opening 22 to sense the proximity of the banknote P. It consists of a sensor 56.

As the proximity sensor 56, a non-contact sensor such as a photo sensor can be used, and the proximity sensor 56 detects that the user's hand or the bill P is approaching the bill insertion slot 50, and thus the vending machine is not shown. Send a signal to the control unit. The control unit controls the driving of the solenoid 54 according to the signal of the proximity sensor 56.

The solenoid 54 has a drive shaft 54a which protrudes from the inside when it is energized. The solenoid 54 is installed inclined inside the vending machine door 20 so as to form an acute angle with the extension line of the cover 51 and the lever 53 in the closed position. As the solenoid 54 is inclined in this way, the drive shaft 54a can press the lever 53 until the cover 51 is completely opened along the rotation direction of the lever 53.

It is preferable that the lever 53 is integrally formed with the lid 51 so that the lever 53 can rotate in association with the lid 51 about the hinge shaft 52.

As the spring 55, a tension coil spring is used.
