A through dovetailing jig assembly comprised of a dovetailing jig removably attached to a workpiece, an indexing strip removably attached to the workpiece and jig, and a front backup board removably attached to the workpiece and jig. The jig is further comprised of a removable pin insert and a removable tail insert.

A drill bit dresser having a dresser body, a holding clamp slidably joined to the dresser body, and a sanding shoe pivotally attached to the dresser body. The dresser body has means for changing the rake angle of the sanding shoe to accommodate different drill types. A drill bit, leading end first, is inserted into the dresser body and held in a desired positioned by the holding clamp. The sanding shoe is pivoted to the dresser body and engages the drill bit leading end in a vertical up and down motion.

Drill bit dresser

A foldable multiple mode imaging acquisition apparatus, such as a camera, having a first and second housing assembly; an erecting assembly interconnected to and between the first and second housing assemblies for allowing movement of the housing assemblies between a folded first condition and an unfolded second condition; a pair of hand gripping sections to allow a user to easily and in a stable manner grip the apparatus in both the first and second conditions without having to remove hands from the first housing assembly and while the assemblies transition between the first and second conditions; a viewfinder assembly mounted adjacent a distal end portion of the second assembly and oriented such that an operator can hold the apparatus in a generally vertical mode when the housing assemblies are in the first folded condition and view the scene, and in a generally horizontal mode when the housing assemblies are in the second unfolded condition and view the same scene.

Multiple mode imaging system

A foldable camera having a base housing containing a self-developing film unit, and an upper housing including an objective lens. The housings extend generally parallel to each other, and in the folded inoperative position, the upper housing overlies and engages the lower housing forming a compact unit. In moving between the folded and unfolded positions, the upper housing moves through planes generally parallel to the base housing, such action being provided by a linkage. A foldable flash unit is movable between a folded inoperative position extending over the upper housing and covering the objective lens, and an unfolded position projecting above the upper housing to expose a flash. In one preferred embodiment, a viewfinder housing is mounted by a linkage to the upper housing for movement between a folded inoperative position extending in a passage formed in the upper housing and an unfolded operative position projected above and extending generally parallel to the upper housing and exposing a viewfinder lens located in the viewfinder housing.

Folding camera

A photographic apparatus for use with self-developing film wherein the apparatus comprises a light-tight housing assembly having a film unit exit for allowing the film units to exit the housing assembly; an exposure control assembly including a shutter button; the exposure control assembly includes a biased carriage assembly movable between ambient, strobe and strobe charge positions in response to manual displacement thereof; a spread roller assembly including spread rollers for spreading the processing fluid in the film units; a manually operable drive mechanism is mounted in the housing assembly for bidirectional linear movement between extended and retracted positions and carries a pick for engaging and advancing a topmost film unit of the film stack into the nip, and for rotatably driving the spread roller member in response to pulling of the drive mechanism by an operator to process the film unit and eject the same from the exit; and, an interlocking assembly cooperates with the shutter button and the drive mechanism to prevent the drive mechanism from moving until the shutter button is actuated, and preventing the drive mechanism from being reinserted into the housing assembly until the drive mechanism has been pulled sufficiently so that a film unit has been processed by the spread roller member and exits the housing assembly.

Self-developing camera

The principal embodiment of the present invention is a preloaded single-use instant camera. The single-use instant camera is provided with user-inaccessible film holding compartment in a sealed light-tight enclosure and a predetermined number of pressure-processable film units stacked in said compartment. The preloaded single-use instant camera is also provided with user operated manual means for sequentially withdrawing the preloaded pressure-processable film units, whereby withdrawal effect processing of said units.

Preloaded single-use instant camera

A photographic apparatus combines an image capturing apparatus with an image rendering apparatus, where the image capturing apparatus operates as an electronic camera and has an integral liquid crystal display panel for viewing acquired images prior to printing the images onto a photosensitive medium. The images are individually selectable to adjust image properties prior to transmittal of the image to a high-resolution liquid-crystal display in the image rendering apparatus. The image rendering apparatus produces an image on the photosensitive medium by projecting illumination through the image present in the high-resolution liquid-crystal display, through a copy lens, and onto the medium.

Electronic still camera with printing capability

A self-developing camera is disclosed which comprises a housing assembly including a film exit opening. Provision is made for an objective lens assembly mounted on the housing assembly and which defines an optical axis for optically capturing images of a scene and directing the images to a focal plane. A mirror in the housing assembly redirects the scene light from the objective lens assembly to a film unit of the self-developing type adjacent the focal plane. The mirror is in an operative orientation generally below the optical axis when the camera is held in a generally horizontal image capture mode.

Foldable photographic camera

A foldable camera having a reflex mirror for redirecting image bearing light rays from the camera's lens to a film unit located in a cassette. An upper and lower housing interconnected by a flexible bellows are pivotally connected to one another for movement between a folded inoperative position and an erected operable position. When the upper housing is erected, the reflex mirror is simultaneously pivoted about an axis which is neither perpendicular to or parallel with the optical axis of the lens so as to dispose the mirror in an erected position permitting the camera to assume a low profile in the fully erected operable position.

Reflex camera having pivotable mirror

A camera including a plurality of housings pivotally coupled to each other for movement from a collapsed compact position in which a subject may be framed in a viewfinder of the camera, to an erected position during which an exposure of the subject may be made, and then returned to their original collapsed position. The movement of the housings from the collapsed to the erected and then back to the collapsed position is in response to the actuation of the camera's shutter release.

Collapsible camera

A camera for use with instant film includes a spread roller assembly including superposed rollers for spreading a processing liquid between predetermined layers of an exposed film unit to initiate the formation of a visible image therein while simultaneously advancing the film unit to the exterior of the camera. The spread roller assembly is pivotally coupled to a housing of the camera for movement between its operative spreading position and an inoperative position wherein the spread rollers are more easily accessible for maintenance procedures, the movement being in response to the manual movement of a light shield into an inoperative position.

Pivotally mounted spread roller assembly

A folding camera of the self-developing type having a housing containing a film cassette, the housing being movable into and out of an erected picture taking position in which an end of the film cassette is exposed to ambient light. A shade having a laterally extending opening therein dimensioned to permit the passage therethrough of a film unit is mounted on the housing for movement between a first position, wherein the opening is in alignment with a film exit slot in the film cassette when the housing is in a collapsed position, and a second position wherein the shade prevents entry of ambient light into the film cassette via its slot when the housing is moving into and out of an erected position.
