摘要： A flash case, in which a flash is provided, is automatically moved to an up position, when a user selects a flash mode in a state where the flash case is at a down position, when a user begins to forcibly raise the flash case by hand in a state where the flash case is at the down position, or when the flash case is at the down position in a state where a photometric operation starts in an auto-flash mode. The flash case is automatically moved to the down position, when an external force is added to the flash case at the up position.

摘要： A pinion gear is fixed on a rotating shaft of a motor for supplying a driving force of a plurality of driving mechanisms. A speed reducing gear is engaged with the pinion gear, and a sun gear is engaged with a speed reducing gear. A planet worm includes a spur gear portion and a worm gear portion. The spur gear portion is engaged with the sun gear. The planet worm is supported so as to be rotatable around the shaft of the sun gear. When the planet worm is rotated to be positioned adjacent to the cartridge room, the worm gear portion is engaged with a rewind spur gear of a gear train. The rotational force of the motor is transmitted to a rewinding fork through the gear train, and then the rewind fork is rotated.

摘要： A first motor is provided adjacent to a spool. The rotational force of the first motor can be transmitted to the spool through a gear train and can be transmitted to an up-down operating mechanism of the flash case through a cam gear. The change of the transmission path of the rotational force of the first motor is performed by a first change mechanism. The transmitting mechanism including the first change mechanism is provided at the upper side of the spool. A second motor is provide adjacent to a bottom of a cartridge room. The rotational force of the second motor can be transmitted to a rewind fork in the cartridge room, and can be transmitted to a driving mechanism of a quick return mirror, a diaphragm, and a shutter. The change of the transmission path of the rotational force of the second motor is performed by a second change mechanism.
