  • Patent number: 5923911
    Abstract: A consecutive taking camera has 16 taking lenses (13a-13p). Time-sequential exposures can be taken in 16 sub-frames (74a-74h, 75a-75h) upon shutter releasing at one time, the sub-frames (74a-74h, 75a-75h) arranged on photo film in a direction of transport of the photo film. A stationary plate (26) is disposed behind the taking lenses (13a-13p), and has 16 stationary openings (31a-31p) through which light entered into respective the taking lenses (13a-13p) is passed. Shutter disks (32-39) are disposed behind the taking lenses (13a-13p), have a shutter slit, and are rotatable to move the shutter slit (32a-39a) past the 16 stationary openings (31a-31p). A consecutive mode and a one-shot mode are selectively designated: the former for taking the time-sequential exposures in 2 to 16 sub-frames (74a-74h, 75a-75h) upon the shutter releasing at the one time, and the latter for taking one exposure in one of the sub-frames (74a-74h, 75a-75h) upon shutter releasing.

  • Patent number: 5534955
    Abstract: A reflection prevention film coats a backside of a stage glass by a vacuum evaporation and coating, etc. A light from a metal halide lamp is not reflected on the back of the stage glass by the reflection preventing film, and is transmitted through the stage glass and is reflected on a surface of the stage glass and a transparent manuscript. The light reflected on the surface of the stage glass and the transparent manuscript enters a projection lens unit and appears as a spot light on a screen, but because the light is not reflected on the backside of the stage glass, so that the amount of the light, which causes the spot light, can be reduced. As a result, the spot light on the screen is inconspicuous.

  • Patent number: 5467198
    Abstract: A method for controlling an image processing system comprising a fax-terminal and an image scanner connected to each other involves producing image signals by the image scanner and inputting them into the fax-terminal. When the fax-terminal accesses a telephone circuit, and if an original document is set in the fax-terminal, an image of the original and then the image picked up by the image scanner are transmitted in succession by facsimile. If the fax-terminal does not access a telephone circuit, the image signals from the image scanner are supplied to the fax-terminal which makes a hard copy of the scanned image. When the scanned image has been transmitted, a hard copy of the transmitted image can be made by the fax-terminal after the access to the telephone circuit is released. The access between the telephone circuit and the fax-terminal is maintained for a predetermined time interval after one image frame has been picked up and transmitted.

  • Patent number: 5317350
    Abstract: An overhead projector has a stage on which original material is placed. The stage has a Fresnel mirror. An electrostatic attracting structure is integral with the Fresnel mirror. The attracting structure includes a conductive membrane of ceramic and a resinous dielectric/protective layer. The conductive membrane consists of a pair of comb-shaped electrodes, which interfinger in coplanar fashion, and are covered by the dielectric/protective layer for insulation and protection. A power supply device applies a high voltage of direct current to the electrodes. The original material is attracted electrostatically by the electrodes, and can be kept flat on the stage. In a preferred embodiment, the power supply device incorporates a self-starting blocking oscillator, which is adapted to boost the voltage sufficiently for electrostatic attraction.

  • Patent number: 5210557
    Abstract: A continuous taking camera has a plurality of exposure chambers disposed linearly. Two shutter discs rotated by a motor are provided at the back of the exposure chambers. Each shutter disc is formed with two movable shutter openings at positions different in distance from the axis of rotation of the shutter disc. When the motor is energized by a shutter release operation, the motor causes the two shutter discs to perform one rotation for sequentially opening and closing the exposure chambers starting from an outermost exposure chamber. A 35 mm full size original frame is divided in the longitudinal direction of the film into four sub-frames. Scenes for eight sub-frames are taken using two full size original frames.

  • Patent number: 4797699
    Abstract: A focal plane shutter for a camera comprising two sets of parallel blades positioned between the plane of a lens in the camera and the plane of a film set therein and in a parallel relation thereto. These sets of blades are movable in opposite directions between a first position in which they are unfolded to close a shutter aperture and a second position in which they are folded to form a slit to open the shutter aperture. Every two adjoining blades in each set of blades has a smaller overlapping width in their first position than in their second position. This overlapping width in the first position is smaller between two adjoining blades closer to the lens plane than between two adjoining blades closer to the film plane.
