ABSTRACT:
A camera controls its operation according to the data contents of a signal transmitted from an external information output device. The camera includes a detector for detecting the signal transmitted from the information output device, a switch for switching the detector to a detectable state, and a limitation unit for making the detector non-operable irrespective of any state of the switch. Thus, a meaningless detection operation of the detector is limited.
