PROBLEM TO BE SOLVED: To design the push-button switch or switches of an elevator call registration device to be easily located visually even in a dark place. SOLUTION: The elevator call registration device, which is installed in an elevator landing and has a light emitting means 6 for lighting a call registration button, is provided with a control means, that is, a call registration relay 3 and a flicker circuit 5, for causing the light emitting means 6 to emit light continuously in a normal state and to emit light in a different manner after any call is registered. The call registration button of the call registration device in that way continuously emits light so as to be located visually with ease by an elevator user even in a place of low illuminance. |
