Abstract:

To provide a locking/unlocking detecting device which facilitates and ensures confirmation of a locking/unlocking state of a locking device, and contributes to a reduction in power consumption.

According to the locking/unlocking detecting device, when a microcomputer 14 determines, in response to detecting signals from an optical sensor 31 and a person detecting sensor 32, that luminous intensity on the periphery of the locking/unlocking detecting device 2 is equal to or less than a predetermined value, that a person is present in a predetermined area, and that a crescent lock is set, the microcomputer 14 outputs an activating signal to a display 18. More specifically, the microcomputer 14 activates the display 18 when the condition that the periphery of the locking/unlocking detecting device 2 is dark, the condition that the person approaches the locking/unlocking detecting device 2, and the condition that the crescent lock is set, are all satisfied. Accordingly, if any of the conditions is not satisfied, the display 18 is not activated.
