ABSTRACT:
A camera includes: a switching circuit for switching the camera between a suspending status and a photographable status; a remote control unit which includes an operation member for conducting a photographing operation and a transmitter for outputting a photographing signal when the operation member is operated; a receiver for receiving the photographing signal; and a control circuit for controlling the camera so that a photographing operation is always conducted in accordance with a receipt of the photographing signal with the receiver when the switching circuit is switched to the photographable status. In order to conserve battery voltage, the control circuit sends a signal to the receiver to turn the receiver off after a set period of time has lapsed and no photographing signal has been received from the control unit.
