ABSTRACT:
In a motor driven camera including a motor which starts upon the first stage of depression of a shutter release button, a clutch mechanism is provided between the motor and a film wind-up member. A shutter releasing circuit is provided which includes a first switch which is closed upon the second stage of depression of the shutter release button, a second switch which is opened upon the completion of shutter release and a third switch which is opened in response to the start of operation of the film wind-up member. A change-over lever changes over the clutch mechanism from a condition in which the rotation of the motor is transmitted to the driving wheel connected with the film wind-up member to a condition in which the rotation of the motor is not transmitted to the drive wheel. When the film wind-up member is returned to its start position after completing the film wind-up operation, the change-over lever is operated to change over the clutch mechanism from the transmission state to the non-transmission state.
