A light-emitting device for emitting light is provided to any one of a top of a hoistway and an upper part of a car, and a light-receiving device for receiving the light from the light-emitting device is provided to another one of the top of the hoistway and the upper part of the car. A controller for controlling an operation of an elevator is capable of switching an operation mode of the elevator between a normal operation mode for moving the car at normal speed and an inspection operation mode for moving the car at a speed lower than the normal speed. The controller performs switching from the normal operation mode to the inspection operation mode when detection of light reception by the light-receiving device is stopped. |
