Abstract

PROBLEM TO BE SOLVED: To announce a door-closing preventive condition to passengers to improve operational efficiency, by counting a light-shading time having no light-receiving detection for a given time, and then actuating a timer to broadcast an attention arousing announcement. SOLUTION: A multibeam door sensor, composed of a light emitting body 2a composed of plural luminous elements 3a, and a light receiving body 2b composed of plural luminous elements 3b, is installed in car doors 1a and 1b. Since the actuation of the multibeam door sensor circuit-closes the normally- opened contact MB of the multibeam door sensor, the circuit of P - the normally-opened contact MB - a timer T - N is formed to excite the timer T for a given time. Also since the normally-opened contact T1 of the timer T is circuit-closed, the circuit of P - the normally-opened contact T1 a speaker action relay - SP - N is formed, to excite the speaker action relay SP. Resultantly a speaker 8, installed on the ceiling part of a cage 7 is actuated to announce information of arousing attention to passengers.
