PURPOSE:To prevent a floor of destination from being registered unless an engine is stopped by providing the control circuit of an operation panel with a key switch for turning on and off the power supply to the circuit, and enabling the key switch to be turned on and off by means of the engine key of any automobile that uses an elevator car. CONSTITUTION:Even if a destination floor registering switch inside an operation panel 3 is operated after an automobile 2 gets into an elevator car 1, the floor of destination cannot be registered since a key switch 8 for turning on and off the circuit power supply to a control circuit 5 is not operating. However, since the key switch 8 for turning on and off the circuit power supply to the control circuit 5 is operable by insertion of the engine key 6 of the automobile 2 into a key hole provided in the operation panel 3, the floor of destination can be registered by control of the destination floor registering switch. After the elevator has landed on the floor desired, the engine key 6 is removed from the key hole 7 so that the circuit power supply to the control circuit 5 is interrupted. |
