  • Patent number: 5764422
    Abstract: A lens drive device for a zoom optical system drives first and second lenses along an optical axis with a single drive source. A transmission mechanism connects the drive source and the first and second lenses. The transmission mechanism transmits drive to the first lens during a first motion range and to the first and second lenses during a second motion range. A focal length of the optical system changes in the first motion range and a focal point position of the optical system changes in the second motion range. The first and second lenses respectively moves in response to movement of a first and second feed screw. A first gear transmits drive from the drive source to the first feed screw while a second gear intermittently transmits drive from the drive source to the second feed screw. A lock lever interlocks with the second gear in response to rotation of a large diameter section of the first gear to thereby arrest movement of the second gear and second feed screw.

  • Patent number: 5740485
    Abstract: A real image viewfinder of an optical device includes an eye piece through which an optical axis may be viewed with respect to a target frame. The target frame may be used for centering an optical image on an image forming plane and also for autofocus of the optical device. The real image viewfinder includes a first prism for redefining an optical axis within the optical device. The first prism has a pair of reflective planes joined about a first ridge line. The first ridge line generally includes a number of manufacturing flaws which are noticeable by the photographer. Thus, viewfinder components are shifted by a predetermined amount to present the first ridge line in an area of the viewfinder which is different from the target frame as viewed through the eye piece. Likewise, the real image viewfinder includes a second prism having a second ridge line which is also shifted away from the target frame as viewed through the eye piece.

  • Patent number: 5729776
    Abstract: A camera equipped with a date imprinting circuit capable of setting multiple imprinting modes and a photographic mode setting circuit capable of setting multiple photographic modes. The camera includes an operational circuit to set and modify the previously mentioned imprinting modes and photographic modes. A detection circuit detects whether or not the camera is in a first state or a second state. A selection circuit modifies the imprinting mode by operating the operational circuit when the detection circuit detects that the camera is in the first state and modifies the photographic mode by operating the operation circuit when the detection circuit detects that the camera is in the second state.

  • Patent number: 5715482
    Abstract: A miniaturized collapsible zoom camera changes viewfinder magnification in accordance with a change in the photographic magnification. The camera is equipped with a collapsible cam tube to cause a first lens group, which rotates around the optical axis, to move from a collapsed position to a position just before a minimum magnification position. Likewise, a zoom cam tube causes the first lens group, which rotates around the optical axis, to move from the minimum magnification position to a maximum magnification position. Sector gears are formed on the outer circumference of the collapsible cam tube and the zoom cam tube. Furthermore, the camera is equipped with a cam tube drive gear which cooperates with the sector gears. A drive motor causes the drive gear to rotate. Another gear cooperates only with the sector gear of the zoom cam tube while a variable power and movement mechanism causes variable power operation in the viewfinder.

  • Patent number: 5708266
    Abstract: An apparatus to detect the amount and direction of rotary motion for use in a vibration compensation system in an optical camera. An indicator disk is provided around the output shaft of a motor which actuates a compensation lens to compensate for vibrations to the camera. The periphery of the indicator disk is provided with a series of holes. A pair of photodetectors, are arranged on the periphery of the disk so as to detect the holes passing thereunder. The two photodetectors are separated by a distance equal to 3/4 of the distance between two holes. By comparing the pattern of signals emitted by the photodetectors the direction of rotation of the indicator disk can be determined. Further, the pulses in the output of either photodetector can be counted to determine the amount of movement. The actual direction and amount of movement as calculated is provided to a vibration compensation circuit as feedback for use in controlling the compensation lens.

  • Patent number: 5706930
    Abstract: When a carrier arm is retracted, a semiconductor wafer carried thereon passes between three light-emitting elements and three light-detecting elements associated therewith. At this time, a controller determines six points on the outer circumferential edge of the semiconductor wafer based on signals from sensors made up of the light-emitting elements and the light-detecting elements. The controller selects three of the determined points, determines the center of a circumscribed circle passing through the selected three points, and regards the determined center as the center of the semiconductor wafer. Then, the controller controls movement of the semiconductor wafer toward a rotary-cup coating device, an evacuating drying device, or an edge cleaning device based on the center of the semiconductor wafer.

  • Patent number: 5707687
    Abstract: A suction chuck and an inner cup are rotated in unison with each other to spread a coating solution uniformly over a planar object in the inner cup under centrifugal forces. Vent holes defined in an outer cup lid which closes an outer cup are held out of communication with vent holes defined in a ring-shaped closure member, so that the interior space in the outer cup is kept out of communication with the exterior space around the outer cup. The concentration of a solvent in the outer cup remains so high that no mist is produced in the outer cup. After the planar object has been coated and before the outer cup lid is opened, the ring-shaped closure member is turned to align the vent holes in the outer cup lid with the vent holes in the ring-shaped closure member, breaking any vacuum in the outer cup with ambient air introduced through the vent holes into the outer cup. Thereafter, the outer and inner cup lids are opened, and the coated planar object is taken out.

  • Patent number: 5694631
    Abstract: A film scroll detection mechanism for a camera does not require a large encoder for use in controlling the scrolling of the film, while still producing a large number of pulse signals, thereby allowing a camera to be made smaller. A connection mechanism links a film scroll detection roller and a pulse signal generator. The connection mechanism causes an encoder of the pulse signal generator to rotate through a larger angle in comparison to the rotation of the aforementioned film scroll detection roller. This allows the encoder to be made with a smaller radius than previous devices. Additionally, the connection mechanism permits the axis of rotation of the encoder to be offset from the axis of rotation of the film scroll detection roller, which allows for a further reduction in the size of the camera.
