  • Patent number: 5473400
    Abstract: A resealable cartridge for sheets of photographic film includes a one-piece, photo-inert and optically opaque polymer tray. The tray has a generally planar bottom wall and front, back and side walls with upper edges and outwardly extending lips. The lip extending from the front wall includes a series of spaced cut-outs. A flexible, photo-inert and optically opaque foil laminate cover for the tray has front, back and side edges. The front edge of the cover includes spaced opening/closing mechanism-engaging apertures which overlie the cutouts in the front lip of the tray. Photo-inert and optically opaque adhesive segments on the lips of the tray provide a resealable opaque seal between the edges of the cover and lips of the tray.

  • Patent number: 5100121
    Abstract: Disclosed is a sheet feeder comprising a magazine in which sheets are stacked, a sucker for sucking a sheet stacked in the magazine, a stepping motor for raising the sucker, and a sheet separation click which is so disposed that an edge of the sheet sucked by the sucker comes into contact with the click when the sucker is raised to a specified position. The sucker is raised at a small pitch when the edge of the sucked sheet comes into contact with the sheet separation click, whereby sheets which have been adhering to the sucked topmost sheet separate therefrom and fall.

  • Patent number: 4874161
    Abstract: A sheet transporting apparatus, for use in laser beam printers, CRT printers or the like wherein the apparatus transports a photosensitive sheet to an exposure station for forming images thereon. The apparatus includes a guide plate for guiding the sheet to the exposure station and a conveyor belt having levers on its outer surface for pushing the trailing edge of the sheet by movement of the lever along the guide plate. The levers cause the sheet to move initially at a speed V1 and then at a speed V2 which is less than a speed V0 at which the sheet is transported to a station for further processing of the sheet.

  • Patent number: 4785321
    Abstract: Between an image forming unit and an automatic developing unit disposed adjacent to the unit, an intermediate chamber having an exhaust device is provided for transferring a photosensitive material from the image forming unit to the developing unit. Even when the vapors of chemical solutions accommodated in the developing unit for development treatment flow into the intermediate chamber through a clearance created in an outlet opening for delivering the material into the developing unit therethrough, the vapors are prevented from flowing into the image forming unit by being temporarily retained in the chamber and released to an exhaust channel.
