Japanese Patent JP2013241225
Kind Code:
A
Abstract:

To prevent a decrease in convenience by preventing unnecessary stop of a passenger conveyor on occurrence of an instantaneous operation caused by contact with baggage and the like in a safety device.

A processing unit (11) constantly monitors an ON/OFF-state of a signal input from a pulsed voltage generator (21) via a contact signal (30) of a safety device. When the signal is not in a pulsed state but steadily in the ON-state, it is determined that a circuit for monitoring an operation of the safety device is broken down. When the signal is kept in the OFF-state for a predetermined period of time or more, it is determined that the safety device is operated.
