  • Patent number: 7330646
    Abstract: A film camera has a body enclosing a light-tight film space. A film unit disposed in the film space, includes a filmstrip having a longitudinally extending row of uniform perforations. The perforations each have at least one concavely-curved edge extending in a direction transverse to the filmstrip. The film space is substantially free of skives despite prewinding of the filmstrip in the camera, even if the prewinding is at a high-torque level.

    Abstract: The camera of this invention has a film cassette compartment, a film spool (13), a film exposing area, and an interlock that prevents moving exposed film from the film cassette. With the camera, a film cassette (2) is loaded into the film cassette compartment. The film is then locaded by moving the film from the film cassette (2) compartment across the film exposing area and winding all but the first frame of film to be exposed around the film spool. After a picture taken, the exposed film is wound back into the film cassette and the next from of film to be exposed is moved into the film exposing area. The interlock prevents moving the exposed film out of the film exposing area. In an embodiment the interlock includes a lever that is engageable with the serrations of a film rewind wheel (22) to prevent movement of the film rewind wheel (22).

  • Patent number: 6580878
    Abstract: The invention relates to a shutter release apparatus for use in a camera for capturing images on a perforated film. The shutter release apparatus has a rotatable thumb wheel movable along an axis between a start position and a trigger position. A sprocket is provided having teeth to engage perforations on the film and to move therewith during film winding. A biased lever is moved by the sprocket against the bias from a position holding the thumb wheel in the start position to a position releasing the thumb wheel for urged movement into the trigger position. The thumb wheel blocks biased movement of the lever when the thumb wheel is in the trigger position and movement of the thumb wheel from the trigger position to the start position releases the lever for biased movement to drive the shutter to expose the film.

    Abstract: A camera comprising a film winder rotatable to wind individual frames of a filmstrip into a take-up chamber after each frame is exposed, and a frame counter rotatable to indicate how many frames are left to be exposed, is characterized in that a locking device is movable to secure the film winder and the frame counter in place to prevent their further rotation responsive to the frame counter being rotated to indicate there are no frames left to be exposed.

  • Patent number: 5628040
    Abstract: A film transfer device of a camera, which consists of a charging means for controlling one frame transfer of a film. The charging means is engaged with a winding part and a rewind spindle RS. A sprocket is designed to rotate independently from the winding part and the rewind spindle RS. A second clutch means is provided to compensate for the speed difference between the sprocket and the winding part on film winding or between the sprocket and the rewind spindle on film rewinding.

  • Patent number: 5625431
    Abstract: A film winding unit is removably attached to a film unit so as to engage a coupling gear with a film winding wheel. The coupling gear is connectable to a gear train through a clutch member. While the film winding wheel of the film unit is unlocked, the clutch member is placed in a power transmitting position for transmitting rotational movement of a motor to the coupling gear through the gear train. Upon the film winding mechanism being locked, a large load is applied to the clutch member, so that the clutch member slips into a disconnecting position to disconnect the motor from the coupling gear. In cooperation with the movement of the clutch member into the disconnecting position, a motor inactivating device inactivates the motor. After a release button of a film winding unit is depressed to depress a shutter button of the film unit, a motor activating device activates the motor in cooperation with returning movement of the release button.

  • Patent number: 5614975
    Abstract: A photographic camera, including a moveable exposure initiation member, is provided with a film brake that is applied by movement of the member to initiate an exposure. The brake engages an element of the film advancing mechanism and thereby arrests film movement during the exposure. The brake is released after the exposure when the member returns to its original position.A method of assembling a camera also is provided using certain parts reassembled and reused from a single-use camera with a film brake as noted above.

  • Patent number: 5576790
    Abstract: A camera comprises manually rotatable film winding means, and a uni-directional clutch coupled to the film winding means to permit film winding rotation of the film winding means and to prevent reverse rotation of the film winding means. The film winding means includes a rotatable winder wheel having a toothed periphery. The uni-directional clutch includes a rotatable idler wheel having a toothed periphery engaging the toothed periphery of the winding wheel and provided with less teeth than the toothed periphery of the winding wheel, and a coil spring coiled tightly about a shank of the idler wheel and having an end portion secured with respect to the shank. The coil spring tightens on the shank to prevent the idler wheel and the winding wheel from being engagingly rotated when reverse rotation of the film winding means is attempted and relaxes on the shank to permit the idler wheel and the winding wheel to be engagingly rotated when film winding rotation of the film winding means is initiated.
