发明名称 Motor driven camera
摘要 A motor driven camera includes a plurality of motors for independently driving individual actuators of a camera such as film winder, shutter charger, a drive associated with a movable reflecting mirror and diaphragm driver. In addition, the camera includes a storage battery, a drive circuit for feeding the power from the battery to the plurality of motors, and a controller which controls the drive circuit. In accordance with the invention, a film winding rate or the rotational speed of a motor which performs a shutter charging operation or the speed of operation of the movable reflecting mirror or the voltage of the power supply is detected, and the plurality of motors are automatically switched between the concurrent drive and the sequential drive in accordance with the detected value. Subsequent to the switching, either drive to which the operation is switched is maintained.
