Abstract: A mount lock apparatus for a camera includes a projecting exterior portion provided substantially at a central portion of a front surface of a camera body; a circular annular mount plate, which is fitted to the projecting exterior portion, and to which a photographing lens unit is detachably attached; a mount lock pin which is biased to protrude from the circular annular mount plate to engage with the photographing lens unit; and a mount unlocking button which is operated to move the mount lock pin in a direction to retract from the connecting surface. The mount unlocking button is provided on a portion of an outer peripheral surface of the projecting exterior portion that is located closer to a lens optical axis thereof than a farthermost portion of the projecting exterior portion from the lens optical axis in a horizontal direction of the camera body.

Abstract: 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.

Abstract: An adapter has a plug, a jack, and a flexible cable, which connects the plug and the jack. The plug is connected to a socket provided in a camera body. The jack is connected to a camera accessory, which is a release switch device, for example. The jack is provided with a clip which is fixed to a strap attaching ring provided on the camera body or a strap attached to the strap attaching ring.
