Abstract: The present invention relates to an elevator button facilitating number identification. According to the present invention, the elevator button facilitating number identification enables a button corresponding to each floor to be easily identified since the number of the button is always turned on. An edge of the button corresponding to the selected floor is turned on so that a user checks the button pushed. Also, after an elevator door is closed and a predetermined time passes, the lighted number of the unselected button is automatically turned off. So, the user can easily check the selected floor. Moreover, when the elevator door is opened, the numbers of the unselected buttons are automatically turned on so that the user can easily select the desired button. The elevator button facilitating the number identification includes: the multiple buttons formed to control an elevator installed in a building and emitting light from a first light emitting body and a second light emitting body individually installed in the number and the edge; and a control unit controlling the elevator by input of the button and emitting the light by controlling the first light emitting body indicating the number of the button and the second light emitting unit of the edge. The button indicates the number to the outside as the first light emitting body formed in the numbers of all buttons always emits the light by a control signal of the control unit. Also, the second light emitting body, formed at the edge, of only the button pushed is lighted. Therefore, both the number and the edge emit light. After the door of the elevator is closed, the first light emitting body of the buttons, except for the selected button after the time preset in the control unit, is turned off. When the door of the elevator is opened, the first light emitting body of the buttons turned off emits the light again.
