タ装置。 A container containing a liquid, a light source that illuminates the inside of the container,
An earthquake sensor is provided with a photoelectric conversion element that receives light inside the container and converts it into an electrical signal.When the electrical signal reaches a predetermined value or more, a command to stop the nearest floor is issued to the elevator control device. In an elevator equipped with a signal processing device that issues an operation prohibition command,
The signal processing device includes a comparator that determines whether the electrical signal is an arbitrary value smaller than the predetermined value, and a timer that outputs an output signal when a predetermined time elapses after the comparator determines that the electrical signal is less than the predetermined value. An elevator system comprising an earthquake sensor, comprising: a canceling means for canceling the operation prohibition command upon receiving an output signal from the timer.
