After completion of (step S6
2), reset the earthquake detector 3 (step S64),
Normal operation of the elevator is started (step S65).

Therefore, according to the above embodiment, after the conventional seismic control operation ends, the elevator stops at the nearest floor, the door is closed, and the lighting in the car room is turned off. In the following cases, the inspection operation is automatically performed (one round trip from the bottom floor to the top floor at low speed) without depending on the inspection by a professional engineer.

At this time, the abnormality detection device detects the presence or absence of abnormality (when vibration or noise during normal low speed operation is higher than a certain level). If no abnormality is detected, the seismic detector operating circuit is activated to cause an earthquake. Since the sensor is reset and the elevator is safely returned to normal operation, a quick inspection work can be carried out without manpower in the case of a comparatively small earthquake in which the elevator-related equipment does not become abnormal.
