To easily discover a lost remote control transmitter by generating vibrations in the case of receiving a control signal transmitted from a camera.

On pressing a control button on the back of a camera 1, a control switch is switched on, and a microcomputer of the camera instructs a 1st transmission means to transmit an electric wave control signal from an antenna 20. As the result, a remote control transmitter 3 at an unknown position receives the electric wave. Then, the remote control transmitter 3 receives the control signal via an antenna 34, and a remote control microcomputer receives the control signal from a 2nd receiving means. When the remote control microcomputer receives the control signal, the remote control microcomputer makes a vibration generating means start operating. At the same time, the remote control microcomputer drives a sound generating means to deep it in a small sound volume based on a small sound volume data fetched from a sound data memory. When the remote control transmitter 3 is found, the user takes it on hand, pushes a stop button 32 to switch on a stop switch.
