摘要： A shutter control device comprises three timing circuits and a switching circuit, and in a first timing circuit a first capacitor is charged by photoconductive current generated by a photoconductive cell. The switching circuit is controlled by the voltage of the first capacitor. A second timing circuit has a second capacitor the charging of which is actuated by the switching circuit simultaneously with the actuation of the first timing circuit and is charged as a function of the delay of the first timing circuit. A third timing circuit has a third capacitor and a shorting switch opened in response to the shutter opening after the first capacitor is charged to a predetermined level. The switching circuit triggers shutter closing through an electromagnet when the third capacitor is charged to the voltage equal to that of the second capacitor.

摘要： A self-processing camera is adapted to receive and contain a plurality of film units, each including an image recording unit consisting of a light sensitive sheet and a superimposed image receiving sheet, with a rupturable portion containing processing agent provided on one side of image recording unit and a trap for receiving excessive processing agent provided on the other side thereof. After each film unit has been exposed, it is individually transported by a film unit transporting frame, so as to effect the processing of the image recording unit as well as the discharge of the image recording unit thus processed. The transporting frame effects a reciprocating movement relative to the camera body, and means are provided to prevent the frame from moving in a reverse direction at least when in the advancing movement, so the exposed film unit is carried between and through pressure members which rupture the portion containing the processing agent and cause the processing agent to be uniformly distributed over the image recording unit. At the completion of the advancing movement, the transporting frame is released from said reverse-movement-prevented condition to effect a return motion, thereby separating the exposed image recording unit from the film unit and then discharging the former outside the camera body.

摘要： At least two timing circuits, one of which is responsive to the light intensity of the object and another of which is set at a fixed delay, are actuated simultaneously to control the opening and closing of a shutter or curtain mechanism in a through-thelens type measuring system. One of the timing circuits is used to open the shutter mechanism and another timing circuit controls the closing of the shutter mechanism. A third timing circuit may be added which has a constant delay equal to that of the another timing circuit and actuates the shutter opening mechanism after an elapsed time interval. The three timing circuits are connected in a series-parallel manner to effect the proper addition and subtraction of their respective time intervals.

摘要： A mechanism for switching from daylight to flash photography and for automatically adjusting the diaphragm aperture to an opening determined by the focusing mechanism. Both the diaphragm aperture and focusing settings are obtained from respective rotating members with a lever riding on a cammed surface of the focusing means and a stop lever mechanism having an angular position determined by the setting of the focusing mechanism. When the brightness of the object is lower than a threshold level, an electromagnet is actuated to cause the stop lever to engage a protrusion on the diaphragm adjustment means thereby stopping the aperture at a setting determined by the focus.

摘要： A foldable strobo discharge flash system comprising a cylindrical strobo discharge tube and a reflecting mirror forming a cylindrical curved surface which has the discharge tube at its focal line and is made of flexible and elastic metal plate so as to be folded compactly. One of the edges of the flexible reflecting plate is set on a movable frame member supporting the strobo discharge tube and the curvature of the reflecting plate is varied in coordinating with the operation of the movable frame member. At a full open state of the movable frame member the reflecting plate becomes a reflecting mirror for the strobo discharge tube and at a closed state the reflecting plate is folded flat. Further, the power switch of the strobo discharge tube is turned on or off in coordinating with the operation of the movable frame member.
