Abstract
A call registration apparatus for an elevator system includes a call registration lamp and a car call button disposed in an elevator car and connected by a common signal line to a CPU. When the call button is pressed a first time, the CPU registers a call and turns on the call registration lamp. When the elevator car reaches a floor, the CPU makes the call registration lamp flicker. If the call button is pressed while the lamp is flickering, the CPU performs a door opening or door closing operation.
