Abstract

PURPOSE: To improve reliability on locking confirmation by detecting the interruption of light by locking and transmitting a locking signal. CONSTITUTION: When a rotational engaging member and a fixing engaging member constituting a lock body are engaged mutually and the lock body is locked, light from a light-emitting element 19A is interrupted by the rotational engaging member or the fixing engaging member and is not received by photodetector 20A, and a transmission section 21 outputs a locking signal. The locking signal is transmitted in a wireless or wire manner, a received by a reception section 24. A CPU 25 decides locking by the reception result of the reception section 24, and displays a decision result on a display section 26.
