Document Type and Number:
Japanese Patent JPS6417978
Kind Code:
A
Abstract:
PURPOSE: To improve reliability on locking confirmation by driving a switch in a detecting unit by an operating piece and transmitting a locking signal.
CONSTITUTION: When a rotational engaging member 17 and a fixing engaging member 18 constituting a lock 14 are engaged mutually and the lock 14 is locked, a permanent magnet 20 as an operating piece drives a magnetic proximity switch 21 in a detecting unit 19. A transmission section 23 in the detecting unit 19 outputs locking signals in response to the driving of the magnetic proximity switch 21. The locking signals are transmitted in a wireless or wire manner, and received by a receiver 24. A CPU 25 decides locking by the reception results of the receiver 24.
