ABSTRACT:
A charge circuit for secondary batteries. The charge circuit encompasses a control circuit having as a power source accumulators chargeable with the current resulting from the electromotive force of a plural number of solar batteries built in a camera. The plural number of the solar batteries are distributed at a plural number of portions on the exterior of the camera. The plural number of the solar batteries are connected in series or parallel or, in accordance with necessity, a serial-parallel connection change-over of the solar batteries is carried out. Circuits for comparing the level at both terminals of each solar battery and for short-circuiting the terminal in accordance with the result of the comparison are provided.
