PURPOSE:To perform diaphragm control and the winding of a film by the same batteries, to improve the efficiency of utilization of the batteries, and to realize a highly reliable diaphragm controller, by providing specific energy charging means, switches, etc. CONSTITUTION:The motor driving device of a camera for performing diaphragm control, shutter charging, and film winding operation is provided with charging means C9 and C10 for charging enough energy to drive magnets 35 and 44 for the diaphragm control. Further, those charging means C9 and C10 are provided with converters TR20 and TR21, C6-C8, T, etc., for charging energy, the 1st switches SW1-SW1', SW2-SW2', etc., for operating a light measuring circuit C, and the 2nd switch SW5, etc., for operating a winding motor 23. By the energy of a battery B1 on the motor driving device side, said various operations including the diaphragm control of the camera are achieved. |
