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: 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.

Abstract: An exposure-condition setting device for a camera includes an Xv dial for setting an exposure compensation value, having a plurality of exposure compensation value indicia, the exposure compensation value indicia representing exposure compensation values; and an AEB dial provided coaxial to the Xv dial and relatively rotatable thereto, for setting an automatic exposure bracketing mode having at least one pair of range marks in the circumferential direction thereof, the pair of range marks representing an exposure compensation range in the automatic exposure bracketing mode when the automatic exposure bracketing mode is set by the AEB dial. An interval of the pair of range marks in the circumferential direction is determined so that the pair of range marks registers with a pair of exposure compensation value indicia on the Xv dial so as to indicate the exposure compensation range for the automatic exposure mode.

Abstract: A camera having a data imprinting function, includes a data imprinting device for imprinting data on film, the data imprinting device including a light emitter which emits light to the film from the film base surf ace side of the film in accordance with character information; a film-type identifying device for identifying the sensitivity of the film; and a controller for determining a quantity of light emitted by the light emitter in accordance with the sensitivity of the film identified by the film-type identifying device, and for adjusting the quantity of light in accordance with the sensitivity of the film.

Abstract: A remote control auto-focus camera system includes a camera body; a transmitter provided separately from the camera body, wherein the transmitter transmits a remote control signal; a focusing device, a photometering device and an exposure device, provided in the camera body; a photographing operation member, provided on the camera body, which is adapted to operate both the photometering device and the focusing device upon a first operation thereof and to operate the exposure device upon a second operation thereof; and a controller adapted to operate the photometering device and the exposure device in this order without operating the focusing device upon receipt of the remote control signal transmitted.

Abstract: A method for controlling a preview apparatus which is actuated by a preview switch which can be actuated externally, in an AF single lens reflex camera, wherein when the preview switch is turned ON, the AF operation is carried out before a stop-down operation to move a diaphragm from a full-open position to a set diaphragm position begins.

Abstract: A preview apparatus in a single lens reflex camera is provided in which a mirror drive mechanism, a diaphragm drive mechanism, and a shutter are driven in association with the rotation of a single-revolution cam gear which is driven by a motor. When the release switch is turned ON, the one-turn cam gear is rotated by single-revolution in the forward direction, and when an external preview switch is turned ON, the preview operation is carried out by the reverse rotation of the single-revolution cam gear within a predetermined angle range in which the stop-down operation takes place without causing an upward movement of the mirror.

Abstract: A method for controlling a single lens reflex camera having a preview function is provided in which a mirror drive mechanism, a diaphragm drive mechanism, and a shutter are driven in association with the rotation of a single-revolution cam gear which is driven by a motor. When the release switch is turned ON, the single-revolution cam gear is rotated by a single revolution in the forward direction, and when an external preview switch is turned ON, the preview operation is carried out by the reverse rotation of the single-revolution cam gear within a predetermined angle range in which the stop-down operation takes place without causing an upward movement of the mirror. When the release switch is turned ON during the preview operation, the motor is rotated in the forward direction until the single revolution cam gear is returned to the initial position, so that the photometering operation is carried out at the full-open aperture position.
