PROBLEM TO BE SOLVED: To reduce the damage to passengers occurring when a landing door is opened or closed by providing a long light reception section arranged with multiple light receivers flush with each other at the prescribed intervals on a column located to face a long light projection section. SOLUTION: When the hand 15 of an elevator user approaches a landing door 1A and interrupts the light 3a emitted from a long light projection section 3 while the landing door 1A is opened and a circuit P-7b-8a-14b-9-N is formed to close the landing door 1A via the excitation of a door opening/closing relay 9, a long light reception section detects the shading, a shading detecting relay 11 is excited, and a buzzer BZ is rung. A circuit P-12b-11a3-14-N is excited, and the circuit P-7b-8a-14b-9-N is opened. The door opening/closing relay 9 is de-excited, and a door opening action is started. The hand 15 of the user can be prevented from colliding with doors 1A, 1B. |
