    摘要： An automatic rewinding camera wherein an automatic advance of the photographic film by one frame is caused by shutter release operation and rewinding of the photographic film is automatically started when the film is prevented from further advance. The camera has a film-driven sprocket wheel, by the rotation of which film movement signals are produced. A timer circuit maintains, during the passage of a predetermined active time which is shorter than the time required to advance the photographic film by one frame, the camera motor in forward rotation so as to advance the photographic film. The timer circuit is reset by the film movement signals. But when those film signals stop, that is, when the film is fully extended from the cartridge, then the timer is not reset; and the measurement of the full predetermined active time, by the timer, without resetting, results in the motor being reversed to rewind the film.

    摘要： A reflex camera having a reflex mirror and a light-blocking plate which are pivotally mounted for swinging movement so as to move between a viewing position and a photographing position. The reflex camera has a driving mechanism including an electric motor for causing the swing-up and -down movement of the reflex mirror and the light-blocking plate between the above-mentioned two positions, and a position-detecting device to detect the moved positions of the reflex mirror and the light blocking plate so as to control the speed of rotation of the electric motor according to the detected positions, thereby to prevent shocks and vibrations on the reflex mirror and the light-blocking plate.

    摘要： A display device for a camera has a display panel with a digital display unit having seven display segments disposed in a figure-eight shape. The digital display unit displays the number of exposed frames or other exposure information, and in addition, a portion of display segments is utilized for display or for indicating an alarm condition of the camera. In order to clearly recognize the display or alarm of the camera conditions, a character or symbol representative of the display content or alarm content is disposed near a display segment used for both numerical display, and camera condition display or alarm. A display of the film winding state is performed by flashing the laterally elongated display segments positioned between patterns formed sideways of the digital display unit and symbolizing a film supply section and a film winding section.

    摘要： A film wind-up control apparatus of a camera in which a film is transported in zigzag direction passing around at least a guide roller located before an exposure station, is adapted to advance the film a predetermined length of the film when an exposure is made in a predetermined period of time and an extra length in addition to the predetermined length after the predetermined period of time has elapsed, so as to advance that part of the film which was previously positioned around the guide roller, beyond the exposure station. The apparatus is also adapted to indicate the number of possible exposures with one decrement every other occurrence of the extra length of film advance. In this way, film that has become permanently curled around the guide roller never comes to rest in the exposure station; but at the same time, the count of remaining frames is kept accurate.

    摘要： An exposure aperture frame defining an exposure aperture includes at least a pivotable partition member with an inclined guide surface on the inner wall thereof which is pivoted by and thereby permits advancement of a film leader to a film take-up chamber so that the film leader can reach a film take-up chamber without any standstill within the exposure aperture frame. The inclined guide surface permits the forward end of the film leader to ride across the partition member. A spring urges the partition member toward a position in which it encloses the exposure aperture frame. That spring also releasably retains the partition member on a shaft on which it is pivoted. The partition member has a platform member extending toward the take-up chamber, which has an opening therethrough that provides access to the spring.
