The ultraviolet LED board 37 is fastened to this ultraviolet LED board connecting member 442. At the center of the round edge of the rotating shaft 441, a ''-shaped cutout groove is formed.

Accordingly, an ultraviolet LED board rotation detection unit 446 is mounted at the center of the ultraviolet LED board bracket 36 to detect the rotation state of the ultraviolet LED board 37 by detecting the rotation state of the rotation shaft 441. .

The ultraviolet LED board rotation detection unit 446 has an 'n' shape, and a rotation shaft 441 rotates and passes between both ends.

When the ultraviolet LED board rotation detection unit 446 detects the cut groove of the rotating shaft 441, it outputs '1', indicating that the rotating shaft is located in the initial position.

Meanwhile, as the second motor 44 rotates, the rotation shaft 441 rotates, and the ultraviolet LED board 37 rotates clockwise (or counterclockwise) accordingly, so that the straight edge of the rotation shaft 441 Until detected, '0' is output.

The UV LED board (37) has a UV LED (37a), a light-emitting LED (37b) that turns on and off together with the UV LED (37a), and a first through hole (38a) when the UV LED board (37) moves along the bracket guide (361). And a photo interrupter for detecting the second through hole 38b is installed. The photo interrupter consists of a light-emitting light sensor and a light-receiving sensor.

That is, the first through hole and the second through hole function to limit the movement position of the ultraviolet LED board 37.

The positions of the first through hole and the second through hole are preferably set in consideration of the horizontal width of the kiosk and the rotation angle of the ultraviolet LED.

According to the present invention, when the first motor and the second motor are operated simultaneously, the contact operation panel can be sterilized more quickly by moving the ultraviolet LED board from left to right and simultaneously rotating the ultraviolet LED board.

FIG. 8 is a control block diagram of an ultraviolet sterilizing device for a contact-type operation panel according to the third embodiment of FIG. 7. As shown in FIG. 8, the ultraviolet sterilization device 30 according to the third embodiment includes a human body detection sensor 33, a sterilization area setting unit 392, a first motor 34, and a second motor 34. A motor driving unit 393 that drives the ultraviolet LED board movement state detection unit 36, a CPU 395 that performs a control function of each of these components and an on/off control function of the ultraviolet LED board 37, and a power supply to each of these components. A power supply unit 391 that supplies is provided.

Figure 9 shows a flowchart of a method for controlling the ultraviolet sterilization device of the contact operation panel of the first to third embodiments according to the present invention.

As shown in FIG. 9, when the contact-type operating panel on which the ultraviolet sterilizing device 10 is installed is a vertically long elevator operating button (S1), the human body detection sensor of the ultraviolet sterilizing device 10 of the first embodiment is Detect (S3). If no human body is detected, the UV board is rotated by a motor to a preset angle, and the elevator button is sterilized by the UV LED of the UV board. After a certain period of time, the human body is detected again (S7), and if the human body is not detected (S9), the ultraviolet board is rotated in the opposite direction by a motor to sterilize the elevator button and at the same time move the ultraviolet board to the initial position (S8) ).

On the other hand, if the contact operating panel on which the ultraviolet sterilizing devices 20 and 30 are installed is an elevator button with long horizontal buttons or is installed on the touch panel of an ATM machine or kiosk (S2), the ultraviolet sterilizing device 20 , 30) determines whether it detects the human body (S4). The ultraviolet ray board is moved horizontally from left to right (or right to left) by a motor to sterilize the object (S6). After a certain period of time, the human body is detected again (S8). If the human body is not detected (S10), the UV board is moved in the opposite direction by the motor to sterilize the object and at the same time the UV LED board is moved to its original position (S12).

According to the present invention according to the above-described configuration, the ultraviolet sterilization device for a contact operation panel includes an elevator button panel with buttons formed vertically, an elevator button panel with buttons formed horizontally, and a plurality of buttons horizontally and vertically. It can be mounted on the top of various contact-type operation panels such as this long elevator button panel, ATM operation buttons and touch panels, and kiosk touch panels to effectively sterilize UV rays. In addition, the ultraviolet sterilization device detects the human body using a human body detection function, so the sterilization function operates only when no one is present, making it safe.

In addition, the ultraviolet sterilizing device for a contact-type operating panel according to the present invention operates automatically and continuously without pressing a button, and automatically stops when a person is detected.

In addition, the touch panel of the ATM and the kiosk are completely sterilized with ultraviolet light to prevent infection with infectious diseases, making it possible to use the elevator hygienically. In particular, when applied to the button panels of elevators installed in hospitals where patients infected with infectious diseases are hospitalized, the spread of the disease can be prevented in advance, thereby preventing economic and human losses.
