  • Patent number: 5606420
    Abstract: A camera system has a camera section, a reproduction section and a printer section, the printer section being separably attachable to either the camera section or the reproduction section to form an integral body. The camera system has photoelectric conversion elements and picks up an image of an object to produce image data. The reproduction section processes the image data so as to reproduce the picked-up image on a display screen, and the printer section prints the picked-up image on printing paper based on the image data. The reproduction section may include an output device which transmits the processed image data to a television set having a display screen, and it may also be integrally provided with a monitor having a display screen. The camera system further includes a recording portion electrically connected with the camera section and which records the image data.

  • Patent number: 5486889
    Abstract: Two barrier blades, a barrier interlocking plate and a barrier driver plate are arranged on a base to overlap one another. A first spring is arranged between the barrier interlocking plate and the barrier driver plate. By over-charging the first spring, the barrier blades are tightly closed. A second spring is provided between the barrier driver plate and the base to push both of the two barrier blades through the barrier interlocking plate 2. A through hole and a cutout are formed in the barrier driver plate at positions which do not interfere with the opening and closing loci of the barrier blades. The first and second springs are arranged in the through hole and the cutout, respectively.

  • Patent number: 5467158
    Abstract: A film winding/rewinding mechanism of a camera driven by an ultrasonic wave motor. The winding driving section includes a cylindrical spool and a cylindrical first ultrasonic wave vibrator provided in the spool. A roller urged by a leaf spring is pressed against the peripheral surface of the spool, so that the peripheral surface of the vibrator contacts the inner surface of the spool at a point in the circumferential direction thereof. The film rewinding driving section includes a film rewinding fork, a cylindrical member mounted on the periphery of the rewinding fork, and a cylindrical second ultrasonic wave vibrator provided between the rewinding fork and the cylindrical member. The diameter of the outer circumference of the second ultrasonic wave vibrator is greater than the diameter of the outer circumference of the first vibrator.

  • Patent number: 5094116
    Abstract: An planetary gearing in which a planetary gear is positioned at three or more positions. A sun gear and a planetary carrier are co-axially and rotatably arranged. A planetary gear is rotatably supported by the planetary carrier to engage the sun gear. A plurality of transmission gears are arranged around the sun gear to be selectively engaged with the planetary gear when the planetary gear revolves around the sun gear. Stopper projections are provided on the planetary carrier, each corresponding to each of the transmission gears. An engagement lever is rotatably arranged to take a first position and a second position. The engagement lever at the first position holds the planetary carrier, by selectively engaging one of the stopper projections, to make the planetary gear engage the corresponding transmission gear. On the contrary, the engagement lever at the second position is disengaged from the stopper projections.
