摘要:
A photographic film cartridge typically including a cartidge case having a longitudinal axis, opposite end walls and a film outlet for feeding the film out; a spool extending substantially coaxially with respect to the cartridge case and carried at the opposite end portions by the opposite end walls of the cartridge case for rotation about the longitudinal axis of the spool, the spool being capable of being rotated from outside of the cartridge case; a film wound into a roll on the spool with an end of the film connected with the spool; a slidable cover provided on the cartridge case for slidably moving along a surface of the cartridge case toward the direction inclined to the film feeding direction to slide toward the direction to open and shut the film outlet, and further including device for keeping the film tightly wound into a roll on the spool, whereby the tip end of the film can be fed out hrough the film outlet by rotating the spool in the direction opposite to the film winding direction.
摘要:
This invention relates to a photographic film cartridge including a spool, a film wound into a roll on the spool with one end connected with the spool, and a cartridge case, the spool extending substantially coaxially with respect to the cartridge case and being carried at the opposite end portions by the opposite end walls of the cartridge case for rotation about the longitudinal axis of the spool, the cartridge case being provided with a film outlet through which the film is fed out and a shielding material on inner surfaces of the film outlet for keeping the interior of the cartridge case shielded from external light, characterized in that at least one adhesive material is provided for detachably adhering a winding of the roll of film to an adjacent winding of the roll of the film.

A film cassette assembly has a cassette and a roll of film wound on a spool and contained in the cassette. When the spool is rotated, the roll of film is rotated together with it in order to feed a film leader out of the cassette through a film passage mouth. To rotate the spool and the roll of film together, the film cassette assembly presses an axial end portion of the outermost periphery of the roll of film or presses the film's circumferential peripheral surface. Where the axial end portion of the outermost periphery of the roll of film is to be pressed, at least one of a pair of flanges of the spool is elastically deformed to clamp both axial side edges of the outermost periphery of the roll of film. Where the circumferential surface of the outermost periphery of the roll of film is to be pressed, a projection and an elastic member are provided within the cassette.

A self-advancing film cassette is provided with an auxiliary rotation transmittance structure for reliably transmitting rotation of a spool to the inner turns of a roll of film in order to prevent reverse rotation of the film caused by loosening of the inner turns of the roll of film or inferior bending rigidity. According to one preferred embodiment, a step portion for pushing the bending line of a film trailer is formed on a slit, permitting the end of the film trailer to be inserted therein. In another preferred embodiment, a spool is provided with a resilient member or flap member for urging the inner turns of the roll of film toward its outer turns. The film trailer has increased bending rigidity by having an embossing treatment, applied thereto, or by attaching a skirt thereto.

An apparatus for processing a rolled article has a rotary supporting mechanism for rotatably supporting opposite ends of a photosensitive roll, an end drawing mechanism for drawing a sheet end of the photosensitive roll to a prescribed length, a pressing mechanism for supporting opposite surfaces of the sheet end, and an applying mechanism for applying a joint tape to the sheet end supported by the pressing mechanism in a transverse direction of the photosensitive roll.

An apparatus for adhering ribbons to a cartridge shell plate comprises a conveyor for continuously conveying thin sheets disposed side by side, a pressure adherence unit for pushing two ribbon webs coated with an adhesive against edge portions of the thin sheets which are being conveyed, and a ribbon cutting mechanism for circulating cutter units beside the thin sheets in the direction of conveyance of the thin sheets in synchronization therewith, and swinging cutters of the cutter units to cut the ribbon webs between adjacent thin sheets. The cartridge shell plate is made by intermittently conveying thin sheets, which have been cut in a size equal to the developed length and width dimensions of the cartridge shell plate, by a conveyor, and cutting four corner portions of the thin sheet and then bending the thin sheet into a shiplike cross-sectional shape at a cutting process station and a bending process station disposed along the conveyor.
