Abstract: A photographic viewing system for use with a film unit having images formed in arcuate, or crescent-shaped, rows thereon. The system utilizes a fixed light source for directing light to a selected arcuate row of images which are to be sequentially viewed and an optics system moves along an arcuate path which corresponds to such selected arcuate row of images so as to produce sequential optical images representing the image on the film unit. A viewing means, such as a monocular eyepiece member or a projection system, provides for the viewing of the optical images that are so produced. The rate of image production is controlled by control of a variable speed motor by the operator. The overall system can be fabricated as a compact, lightweight hand-held unit.

Abstract: A film pack by which an existing camera system is adapted to expose and process small format film units. The film pack includes a plurality of film unit and carrier assemblies stacked in a standard film pack container designed to fit the film well of the existing camera. The carrier of each assembly is dimensioned to fit the interior of the container and to support the film unit mounted thereon properly in relation to the optical system of the camera. Each carrier is preferably formed as a two-part assembly to include a film unit carrier slidably supported by an envelope. The carrier and the envelope cooperate with the camera carried processing components in a manner to enclose the film unit in a dark chamber as it is discharged from the camera. Also, a viewfinder mask is provided for the existing camera so that a viewed image will be correlated with the reduced image format of the film unit in the film pack.

Abstract: A film assemblage for use with a camera of the self-developing type having a pair of superposed rollers for rupturing a container of processing liquid attached to an exposed film unit and spreading its contents across a photosensitive layer thereof while simultaneously advancing the exposed film unit toward the exterior of the camera. The assemblage includes a film cassette for housing a plurality of film units and an imbibition chamber which originally functions as a dark slide or cover for protecting the film units from exposure during its insertion into the camera.

Abstract: A camera of the type employing a removable film cartridge including a plurality of individual film units, which are exposed and ejected one by one to complete their development outside the camera, has a base, a motor carried on the base, and an exposure housing and an access door each pivotable with respect to the base. A shutter mechanism, movable between a cocked condition in which exposure can be initiated and a run down condition in which exposure is terminated, is automatically recocked and the film ejected following exposure termination. The gearing for the film ejection mechanism and the shutter recock mechanism, as well as the pivot points of the access door and the exposure housing, are so disposed with respect to each other and to the output gear as to permit smooth engagement and disengagement of the gears during pivotal motion of both door and housing, or either of them.

Abstract: An exposure control apparatus is provided for a photographic camera of the type suitable for use with a source of artificial illumination and includes a follow focus system for determining a maximum exposure aperture in correspondence with lens focusing as a direct function of camera to subject distance. The maximum exposure aperture is determined by the position of an interceptor which is rotated about a select pivot point by the coaction of a cam follower engaged by a cam surface. The cam surface moves in concert with lens focusing in a manner whereby a predetermined number of degrees rotation of the interceptor about the select pivot point corresponds to a predetermined number of F stop changes in the determined maximum exposure aperture. There may also be included means for selectively trimming the determined maximum aperture size defining position of the interceptor by rotating the interceptor about its select pivot point without displacing the cam follower along its associated cam surface.
