Abstract: An extensible and retractable compact self-developing camera including a first camera section for exposing and applying pressure to a self-developing film unit and a second camera section coupled in telescoping relation to the first camera section for mutual movement in opposite directions between extended and retracted positions. When extended, the first and second camera sections cooperate to form a film retention and/or imbibition chamber for receiving film units advanced thereinto by a pair of pressure applying rollers. In the retracted configuration, the second camera section slides over a major portion of the first camera section and forms a protective covering over at least the optical elements mounted thereon.

Abstract: A self-developing camera for exposing, processing, viewing and storing self-developing film units, preferably of the small format transparency type. The camera includes a storage chamber for receiving a supply cassette holding a stack of film units therein, an exposure station, a processing or pressure applying station, and a storage chamber for receiving a storage cassette in which the film units are stored after exposure and the application of a compressive pressure thereto. A movably mounted film viewer on the camera is operative to move a processed film unit out of the storage cassette for viewing and back into the storage cassette for storage without the user of the camera having to manually handle or manipulate the film unit.

Abstract: A photobooth and indexing system that includes a square frame having a motor driven film pack conveyor disposed about its periphery. The conveyor comprises 22 trays; 21 hold film packs and one holds a dummy pack. When a tray is indexed into position under the motorized film pack support, a ram lifts the pack up to an exposure position. A motorized support includes a rotatory solenoid operated pack, a pair of motor driven rollers and a film deflector for spread control. A logic system causes the dark slide to be automatically ejected into a film delivery chute. After 10 exposures, the logic causes the ram to be lowered thereby returning the empty pack to the underlying tray. The conveyor is indexed one tray position and the procedure is repeated. When the last tray arrives at the ram station, the dummy pack is elevated by the ram causing the logic to inhibit further operation of the photobooth until it has been reloaded with fresh film.

Abstract: An automatic photostudio including an apparatus for changing film cassettes in a self-developing camera. The cassette changing apparatus includes a pair of cassette holding magazines located on opposite sides of the camera, an elevator for moving cassettes into and out of the camera, and a shuttle plate mechanism for effecting the dispensing of a cassette alternately from the first and second magazines and for moving the cassette along a guide plate to the elevator.

Abstract: A slide viewer/copier operable in a viewing mode for projecting an image of a slide transparency film unit onto a viewing screen for viewing and a copy mode for projecting an image of the slide onto self-developing film unit for exposure and for processing the film unit to produce a photographic copy of the slide.

Abstract: An adapter for connecting a camera not provided with a tripod socket to a tripod. The adapter comprises a housing, a threaded insert for receiving a tripod screw in the housing, and a dovetail shoe adapted to fit a cooperating dovetail slot in the camera bottom. The dovetail shoe is formed with an opening in which there is a brake assembly movable by a manually operable lever between locked and unlocked positions.

Abstract: A pair of meshing gears, having unique tooth profiles, are provided in a separable gear train which is usable in a self-developing camera to couple a motor in one housing section of the camera to at least one of a pair of pressure-applying rollers mounted on a second camera housing section that is pivotally coupled to the first section for movement between positions blocking and unblocking access to a film container receiving section in the first housing section. The pair of gears have a speed ratio of other than 1:1 and equal tip spacing to facilitate bringing the pair of gears into operative mesh when the second housing section is moved to the operative blocking position.

Abstract: An imbibition chamber adapter configures to be attached to a self-developing camera for receiving a transparency type self-developing film that has been advanced through pressure applying members of the camera.

Abstract: A modular self-developing camera having structure therein for accurately positioning a film container, holding self-developing film units therein, at an operative location within the camera wherein a film unit in the film container is properly orientated with respect to the exposure plane, a film advancing device and a film processing station. The modular camera features a unitized frame for mounting components and subassemblies thereon. The frame is configured to cooperate with portions of a camera housing section to define a receiving chamber for the film container.

Abstract: A thin dark chamber or light shielding adapter that is configured to be slidably inserted through a narrow film exit slot in a self-developing camera for receiving and light shielding self-developing film units of the type requiring a short imbibition period in a light-free environment subsequent to the distribution of a processing composition between predetermined layers of the film unit.

Abstract: Photographic apparatus, preferably a camera, having a reflex optical system for exposing film units which include a transparent outer sheet or layer through which image-bearing light is transmitted to expose photosensitive materials within the film unit. A reflex mirror, forming part of the optical system, is arranged at an optimized position with respect to the camera exposure plane to prevent light rays reflected from the transparent outer sheet from impinging the mirror at an angle of incidence which would redirect the light rays back to the film unit thereby causing a second exposure or "ghost image".

Abstract: A quick release adapter for connecting a cable release or self-timer to a camera and applying a shutter operating force to the shutter button of the camera. The force transmitting mechanism includes an overtravel spring to minimize malfunctions that might occur because of differences in tolerances between cameras, adapters and accessories. The adapter comprises a housing embracing the lensboard of the camera and being detachably connectable to the camera by means of a cam operated latch.

Abstract: This invention relates to a camera back for selective releasable attachment to a front camera body comprising two generally flat housings in end to end pivotal connection with respect to each other wherein the first of the housings is adapted to slidably accept a plurality of stacked film units of the self-developing type therein in a manner whereby the photosensitive surface of the forwardmost film unit is positioned at an exposure window corresponding with the focal plane of the front camera body when the camera back is releasably attached to the front camera body. The second housing defines an imbibing chamber for receipt therein of exposed film units in a light tight environment. One open end of the imbibing chamber includes a pair of processing rollers thereacross in operative association with other film advancing mechanisms which sequentially advance exposed film units from their position at their exposure window of the first housing into the imbibing chamber of the second housing.

Abstract: An adapter for operatively coupling a reflex camera having a preprogrammed automatic cycle of operation to an optical instrument such as a microscope or telescope. The adapter includes mechanisms which permit the operator to selectively modify the preprogrammed cycle of operation for the purpose of making extended time exposures or allowing vibrations induced by the movement of a camera reflex member to subside prior to initiating film exposure.

The headgear is partially suspended from an overhead support by a negator spring and a cable suspension permitting universal movement. Light for examining the retina, and a bright flash of light for photography, are supplied to the headgear over a flexible fiber optics cable under the control of the foot-operated unit and synchronizing contacts on the camera.

Abstract: A processor for extracting a large format self-developing film unit from a cassette, applying a compressive pressure along the length of the film unit to distribute a fluid processing composition between predetermined layers of the film unit, and providing a substantially light-free environment for the film unit for imbibition.
