Summary:PURPOSE:To eliminate influence upon system operation and service by preventing a unit from being extracted owing to the misoperation of a processor having a CPU. CONSTITUTION:When the unit 100 is in operation, a lock mechanism A51 locks the mechanical coupling with a lock mechanism JB52 and the connectors 81 and 82 of the unit 100 and processor main body 200 are held in an engaged state. When an ejector lever 10 is operated so as to extract the unit 100, the CPU 30 is informed of that through an ejector contact 11 and a detecting circuit 20. The CPU 30 sends an indication for alarm generation to an alarm generation/resetting control circuit 60 and performs a standby process for putting the unit 100 out of operation. After the standby process, the locking of the lock mechanism A51 is reset through a lock control circuit 40 to enable the unit 100 to be extracted.
