Abstract:
The present invention provides a method of providing a self-contained processor having a luminescent testing material capable of generating a read-out signal in response to contact with a reagent of interest in a test sample. In an alternate aspect, the present invention also provides a portable and self-contained diagnostic assay system for detecting and recording the presence of a luminescent signal generated by a reaction between a luminescent testing material and a reagent in a test sample on a self-developing film assemblage.
Abstract:
An imaging apparatus and method for use with a film assemblage strip of the self-developing type including an active matrix LCD for providing an area imaging means for exposing the film assemblage at an exposure station, wherein indexing the strip is accomplished by having indexing means of the strip selectively cooperate with pressure applying means, such that when one of the frames on the strip is processed the next successive film frame is simultaneously advanced to the exposure station to be exposed.
Abstract:
An improved self-developing film unit comprising: a processing fluid supply including a rupturable reservoir of processing fluid; an image recording assembly of the self-developing type including first and second overlying layers one of which is exposable to form a latent photographic image, and a spacer connected to and between the first and second layers for providing a processing space therebetween for allowing processing fluid to pass therethrough; a fluid trap at a trailing end portion of the film unit for collecting excess processing fluid traveling through the processing space; a first fluid-tight coupling device including a fluid passage for fluidically coupling the reservoir to a leading end of the processing space for allowing processing fluid from a ruptured reservoir to be introduced into the processing space and initiate processing of the latent image; and, second fluid-tight coupling device including a fluid passage for fluidically coupling a trailing end of the processing space with the trap for allowing processing fluid to enter into the trap; the image recording assembly comprises a photosensitive layer, an image receiving layer in overlying and coextensive relationship to the photosensitive layer; the image receiving layer and the photosensitive layer being of the integral diffusion transfer type; and, the spacer comprises a pair of spaced apart and generally parallel elongated rails coextensive with and adjacent opposed marginal edges of the layers.

Abstract:
A dispenser of film units is operative with a film processing apparatus enclosed within a housing. The housing includes a front sidewall having an exit slot for the delivery of film units, the dispenser including a film ejection device located behind the slot for ejecting film units out of the housing via the slot. The ejection device may include rotating pressure rolls which may also serve a function in the film processing. The dispenser includes a catcher constructed of a four-bar mechanical linkage, and includes a spring urging the catcher from an extended state away from the sidewall to a retracted state contiguous to the sidewall. The catcher is supported pivotally by a strut assembly which pivots from the sidewall and connects to pivots on both the catcher and the sidewall. A flap interconnects the tray with the sidewall. An articulation pivot permits a folding of the flap against the tray during retraction of the catcher. Force exerted by an exiting film unit overcomes the retractive spring force to deflect the tray to the extended catcher state. A pair of flexible hooks in the tray rotate so as to hold side edges of the film units flat against the tray and so as to prevent a folding of the flap against the tray. Retraction is inhibited by the presence of the film unit in the catcher, and proceeds automatically by removal of the film unit from the catcher tray.
Abstract:
There is disclosed an electronic printing apparatus which prints images on successive individual film units held in a cassette. Included in the apparatus is a carriage assembly which mounts the cassette for reciprocating movement along a given path. There is provided a carriage driving mechanism which drives the carriage assembly at different directions and speeds.
Abstract:
A photographic film assemblage including a film cassette having a film spool rotatably supported therein, and a length of self-developing type film coiled about the spool with one of its ends secured to the spool and its other end extending to the exterior of the film cassette for subsequent attachment to a film take-up member of a camera. The spool includes a cylinder and a piston mounted for reciprocating movement within the cylinder. Also located within the cylinder is a supply of processing fluid. After the film has been exposed and rewound into the cassette, the piston is moved deeper into the cylinder to cause the processing fluid to move from the cylinder into an annular chamber which surrounds the cylinder and which contains the film, where it initiates the formation of visible images within the film.
Abstract:
A film assemblage for use with a camera of the self-developing type having a pair of pressure-applying assemblies, e.g., a pair of juxtaposed roller assemblies, for rupturing a container of processing liquid attached to a leading end of an exposed film unit and spreading its contents in a layer between elements of the film unit as it is being advanced between and in engagement with adjacent liquid spreading surfaces of the assemblies so as to initiate the formation of a visible image in the film unit. The film assemblage includes means for pregapping the adjacent liquid spreading surfaces to a degree which will in turn provide a processing liquid layer of an optimum thickness for the film units in that particular film assemblage.
Abstract:
A self-developing microfiche camera for exposing a plurality of micro-image areas arranged in rows and columns on a single card-like film unit. The camera includes a system for controlling operation of an electrical motor in an exposure cycle mode during which the motor drives a barrel cam through a rotational increment to operate the shutter and index the objective lens, and in a reset cycle mode during which the motor advances the barrel cam through as many rotational increments as necessary to return the lens and barrel cam to a predetermined starting position. A shutter latching device is provided to disenable shutter operation during each reset cycle.
