To disuse an FPC for power supply between a camera body and a photographic lens barrel elongating and contracting between an extending position and a housing position.

The camera 10 is equipped with the camera body 11 provided with a first electric circuit 13 actuated by a power source 20 and the photographic lens barrel 12 elongating and contracting between the housing position and the extending position. The lens barrel 12 is provided with a second electric circuit 18 actuated by a secondary battery 25, and the circuit 18 is provided with power receiving terminals (a) and (a) for charging the battery 25, which are displaced according to the elongation and the contraction of the lens barrel 12. The circuit 13 is provided with power feeding terminals (b) and (b) coming into contact with the terminals (a) and (a) when the lens barrel 12 exists at the housing position. Furthermore, the battery 25 is charged with the power of the power source 20 of the camera body 11 by bringing both terminals (a) and (a) and (b) and (b) into contact with each other.
