Abstract: An instant camera is provided with a motor rotatable in normal and reverse directions, a claw member for pushing an exposed film unit out of a film pack, and a pair of spreading rollers for ejecting the exposed film unit from the camera by applying pressure thereto. The motor rotates in the normal direction upon taking a photograph, so that the spreading rollers rotate in normal directions. The force of the motor is simultaneously transmitted to the claw member via a clutch mechanism. An operable member is provided in a film pack chamber. To clean the spreading rollers, the door of the empty film pack chamber is opened. When the operable member is pressed, the motor starts rotating reversely. During the resulting reverse rotation of the spreading rollers, a cloth for wiping the spreading rollers can be applied thereto, so that processing solution or dirt sticking to the rollers can be removed. Reverse rotation of the motor is prevented by the clutch mechanism from being transmitted to the claw member.

Abstract: A film feeding device in a camera comprises drive means having an electric motor, winding-up means driven to wind up an unexposed film, rewinding means driven to rewind an exposed film, change-over means having a winding-up position in which the winding-up means is operatively associated with the drive means and a rewinding position in which the rewinding means is operatively associated with the drive means, the change-over means being for selectively causing the winding-up means and the rewinding means to be engaged with the drive means, means operated to load another new unexposed film into the camera after the film has been rewound by the rewinding means, and control means for moving the change-over means to the rewinding position to drive the rewinding means and moving the change-over means to the winding-up position in response to the operated means.

Abstract: A device for flowing a driving current to a motor to drive the motor comprises a capacitor and means responsive to the charging current flowing into the capacitor to supply the driving current to the motor. The responsive includes charging means for supplying the charging current to the capacitor and means for discharging the charge charged in the capacitor during the supply of the driving current to the motor.
