  • Patent number: 5765066
    Abstract: A camera having a body portion with a cartridge chamber for retaining a film cartridge and a film chamber for retaining a filmstrip includes a cover coupled to the body portion and movable in opposite directions between an opened and a closed position having a gear rack having a set of linearly arranged engagement teeth. A drive gear having an engaging portion for engaging the film cartridge is moved into engagement with the gear rack to wind the filmstrip into the film cartridge when said cover is moved in one of the opposite directions, and is moved out of engagement with the gear rack when the cover is moved in the other direction to prevent film winding.

  • Patent number: 5737656
    Abstract: A camera includes a body portion having a cartridge chamber for retaining a film cartridge and a film chamber for retaining a filmstrip a pump cover coupled to the body portion and movable in opposite directions between an opened and a closed position, as well as a rotatable film winding for engaging the film cartridge to wind filmstrip into the film cartridge as the gear is rotated. An engageable locking lever prevents the gear from being rotated until disengaged by movement of the cover in one of the opposite directions in which a movable gear rack having a set of engagement teeth engages the unlocked film winding gear and rotates the film winding gear when the cover is moved in one of the opposite directions to wind film into a film cartridge.

  • Patent number: 5724622
    Abstract: A camera includes a body portion having a cartridge chamber for a film cartridge and a film chamber for a filmstrip, a high energy lever returnable to a cocked position, and a film metering pawl movable in engagement with the filmstrip. The film metering pawl is placed in engagement with the filmstrip to prevent winding of the filmstrip into the cartridge, and released from engagement when the high energy lever is being returned to its cocked position to permit the filmstrip to be wound into the cartridge. The film metering pawl is movable to a film metered position where it is locked and the film advance is disabled.

  • Patent number: 5701536
    Abstract: A camera includes a depressible shutter relase button; and a film metering mechanism for metering a filmstrip in the camera. The shutter release button is positioned on one side of a pivotable trigger which raises a release element when the shutter release button is depressed. The release element, coupled to the film metering mechanism, remains in a raised position until the film metering mechanism has metered the filmstrip. Preferably, the shutter release can be used in a pump-action camera, the shutter release remaining hidden until a succeeding exposure frame has been advanced and metered.

  • Patent number: 5678109
    Abstract: A camera includes a frame having a movably attached film engaging member including a metering pawl for engaging a contained filmstrip. A light locking cover attached to the frame prevents ambient light from entering a defined light tight enclosure surrounding the film engaging member with the exception of an opening to allow a locking portion of a second movable lever within the lighttight enclosure for engaging the film engaging member. The lever includes an integral light locking portion adjacent the locking portion which blocks the opening of the first light locking cover but allows the locking portion to engage the film engaging member. The access opening of the light locking cover is sufficiently large to allow pivoting movement of the locking portion, the cover preferably including a recess to allow the light blocking portion of the lever to effectively cover the opening in a lighttight manner.
