    摘要： An optical system shifting device for a camera in which an optical system is shifted in the direction of the optical axis by the driving force of a motor, wherein a first positioning member effects the positioning of the optical system in the direction of the optical axis independently of the driving force of the motor, a second positioning member effects the positioning of the optical system in a direction perpendicular to the optical axis of the optical system, and a switching member actuates the motor by giving an external force to the optical system, whereby the functional features as well as maneuverability of the optical system shifting device are improved.

    摘要： The disclosed camera has shutter blades which also serve as diaphragm blades and an auxiliary light-metering aperture arranged, upon operation of the shutter blades, to be opened and closed depending upon opening and closing of a main aperture which lies in the path of light from an object to be photographed to a film. A photo-interpreter composed of a light projection element and a photosensitive element optico-electrically detects the size of the opening of the main aperture of the shutter blades. Once the auxiliary aperture has assumed a totally light blocking state from a pre-opened state, the photo-interpreter produces an output signal that initiates counting of light metering data. During flash photography, a flash device is triggered with a timing to make a proper exposure with a signal representing the required aperture value as detected by the photo-interpreter.

    摘要： An electromagnetic drive device for a camera includes two exciting coils which have the power supply thereto controllable independent of each other. The two exciting coils are disposed either on the inner or outer side of a lens barrel which carries a photo-taking lens. The direction of magnetic flux formed by each of these two exciting coils is shiftable either to the direction of the optical axis of the photo-taking lens or to a direction perpendicular to the optical axis by controlling the direction of the power supply to these two exciting coils. Shifting the photo-taking lens to an in-focus position and controlling the action of a light quantity control member disposed within the lens barrel can be accomplished independently.

    摘要： A camera having an electromagnetically driven shutter provided with a counter capable upon counting a present number producing a signal. Each time the shutter is closed, the counted value is changed, while the period of actuation of the shutter is controlled to effect a predetermined fraction of an exposure, so that a continuous sequence of shots equal in number to that preset in the counter are taken automatically.

    摘要： In an automatically focusing camera, the lens is driven to infinity during film winding and the film winding spool is blocked when film winding is completed. Upon shutter release actuation of the camera, film winding is unblocked when the automatic focusing circuit energizes a first magnet and lens rotation is blocked at the focused position when the automatic focusing circuit energizes a second magnet. A single control member operates to effect blocking of the film winding mechanism and to drive the lens to infinity when rotated in one direction, and to unblock the film winding mechanism when rotated in the opposite direction.
