To provide a mechanism which enables a person performing locking/unlocking to be logged only by addition to a conventional key, even if the key itself is not replaced, particularly, a mechanism which enables the interlock of a time recorder system by being interlocked with the system.
An authentication unit has an opening processing means for receiving the input of user identification information and wirelessly transmitting an opening signal to auxiliary equipment for a lock when the input user identification information is appropriate. The auxiliary equipment for the lock comprises: a shielding body which is large enough to shield the lock; a drive unit for driving the shielding body to a position to make the shielding body shield the lock, or a position to expose the lock; a reception means for receiving the opening signal from a reader; and a control means for controlling the drive unit by receiving the opening signal from the reader, so as to drive the shielding body to the position to open the lock, from the position to shield the lock.
