摘要:
A photographic processor and method of operation is disclosed. The processor includes a circular drum having first and second film processing paths, and a disk positioned inside the drum. The disk comprises a first set of disk teeth for engagement with perforations on a first type of film and a second set of disk teeth for engagement with perforations on a second type of film. The first and second set of disk teeth are positioned along a portion of an outer periphery of the disk. The processor also includes a circular dryer for drying the processed film. The dryer extends around an outer periphery of the drum.

A photographic processor having a circular processing drum is shown. The circular processing drum of the processor of the present invention includes a disk that is positioned inside the drum. In order to accommodate different types of film, the circular processing drum is adjustable to change the width and thereby, change a size of the film path within the circular processing drum.

A latched film unit has a support, a filmstrip held by the support, and a latch mounted to the support. The latch is reversibly switchable between a first state and a second state and can enable or disable an access right of a memory element in the film unit. A latching device operates the film unit.

A film cassette having perforated film for permitting automated extension of the film, the film cassette comprises a core having the film convolutedly wound on the core. A rotatable drum receives the core, and includes a recessed slot and a projection which engages a perforation of the film for permitting motion of the film as the drum is rotated. A shell receives the drum, and includes an opening and a finger that matingly engages the recessed slot of the drum for forcing the film through the opening of the shell and, consequently, out of the film cassette.

A method and apparatus for processing of filmstrip contained in a film cartridge. The apparatus having at least one processing tank for holding a processing solution, a holding mechanism for holding and retaining a film cartridge containing a filmstrip having a leading edge and trailing edge, the trailing edge being secured to the cartridge, a transport mechanism for moving the holding mechanism along the apparatus so that the holding mechanism can be located at a workstation located at one of said at least one processing tank, and a film drive mechanism for moving the film out of or back into the film cartridge while the end of the film is still attached to the cartridge.

A film cartridge is provided with an internal mechanism for engaging and pulling a leading end of film from a roll to extend the film through a cartridge exit port. A one-way clutch, including a rotational element captured in a ramped cage, moves in one direction to capture the film between the ball and cage and advance the film through the exit. Movement in the opposite direction releases the film and repositions the clutch for the next advance. Still more specifically, the cartridge includes a second and opposite working one-way clutch for preventing premature retraction of the film. A release mechanism is employed for disabling both clutches when desired for intentional rewinding.

A film cassette comprises a lighttight housing, a spool rotatably supported inside the housing, a filmstrip wound onto the spool, a film leader attached to a leading end of the filmstrip, and a sprocket coaxially connected to the spool with identical pitch teeth adapted to be received in respective perforations along an edge section of the leader wider than the filmstrip for advancing the leader (but not the filmstrip) from the housing when the sprocket and the spool are rotated in a film unwinding direction. Among the perforations that receive the teeth the perforation closest to the filmstrip is longer than the others to allow anyone of the teeth to readily enter that perforation when the leader is wound onto the spool after the filmstrip.
摘要:
A film assemblage comprises an elongate filmstrip and a relatively shorter leader adhered together at respective overlapping areas and adapted to be wound onto a take-up spool in a camera beginning with the leader and followed by the filmstrip. The filmstrip and/or the leader has a hole located and dimensioned relative to the overlapping areas to receive at least one of the overlapping areas when the leader and the filmstrip are wound onto a take-up spool in a camera. Since one of the overlapping areas is located in the hole when the filmstrip and the leader are coiled tightly about the take-up spool, the double thickness of the overlapping areas will not leave any pressure marks on the filmstrip.
摘要:
Operating mechanism for cameras, particularly of the single use type, in which a first gear wheel depressed by the shutter release button thus unblocks a spring biased slide member initially blocked against movement by engagement of an edge of the slide member with the periphery of the gear wheel. Upon release, the slide member moves partially over the gear wheel and blocks the wheel's spring biased movement to its original position. The slide member actuates the shutter in the course of such movement. A second gear wheel, meshing with the first gear wheel, lies below the slide member and carries a cam which lies in an opening in the slide member and engages the slide member to move it back to its original position when the first gear wheel is rotated by the user to transport film to the next exposure. Lugs carried by the slide member and the second gear wheel cooperate to limit rotation of the gear wheels to that appropriate to film transport to the next exposure. A counter is driven by rotation of the gear wheels.

A film cassette comprises a film spool rotatable inside a lighttight cassette shell to thrust a filmstrip coiled about the spool automatically to the exterior of the shell, and a film exposure status indicator movable from an unexposed position for providing a visible indication that the filmstrip is unexposed to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. According to the invention, the spool and the status indicator include engagable means for moving the status indicator to its exposed position from its unexposed and partly exposed positions only in response to rotation of the spool.
