摘要:
A film container incorporating a light-blocking pile fabric composite disposed in bounding relation to a slit opening in the container. The pile fabric composite includes a heat curable resilient polymeric stiffening primer disposed across the underside of a pile fabric and a layer of substantially solvent free, heat activatable adhesive disposed below the primer and bonded to a bare or coated surface of black pigmented polyvinyl acetate of the container.

An apparatus and method for installing film into a detachable film cassette assembly including a film clip adapted to receive a film cartridge, a winding housing attached to the film clip, and first and second film covers. The method includes coupling the film cartridge to the film clip, inserting the film clip into the first film cover, inserting the second film cover over the film clip, and engaging the first and second film covers to at least partially enclose the film clip between the winding housing and the film cartridge.

A light-shielding cloth that is to be bonded to a slit-form opening of a container for a photosensitive material is formed from a base fabric and a crimped pile thread incorporated into the base fabric so that the pile density is in the range from 45,000 filaments/cm2 to 85,000 filaments/cm2, a hot-melt adhesive region being provided on the reverse side of the base fabric without a filling agent being applied thereto for the purpose of preventing the hot-melt adhesive from penetrating the base fabric. A container for a photosensitive material is formed by bonding the light-shielding cloth to a slit-form opening using a 100% solids adhesive, preferably an ethylene-vinyl acetate copolymer resin based adhesive, without a treatment with a filling agent. A narrow-width light-shielding ribbon is formed by slitting the light-shielding cloth by means of an ultrasonic slitter.

A camera with a device that opens and closes a light lock door of a film cartridge loaded in the camera includes a drive source that moves a photographing lens barrel, and an opening/closing mechanism that uses the drive source to open and close the light lock door. A moving mechanism moves the photographing lens barrel. A switching mechanism is coupled to the drive source, and transmits a driving force from the drive source to a selected one of the moving mechanism and the opening/closing mechanism. When an inhibiting device inhibits movement of the photographing lens barrel and the movement mechanism of the photographing lens barrel, the switching mechanism transmits the driving force to the opening/closing mechanism for the light lock door. When the inhibiting device does not inhibit movement of the photographing lens barrel and its moving mechanism, a braking device prevents the opening/closing mechanism from moving so that the driving force is only supplied to the moving mechanism of the photographing lens barrel.

A photo film cassette contains photo film wound in a roll form, and includes a passage port which has first and second walls between which the photo film is passed. The light-trapping fabric includes a base fabric having first and second surfaces. Pile threads are disposed to protrude from the first surface of the base fabric, for preventing ambient light from entry into the photo film cassette between the first and second walls. In the course of manufacturing the photo film cassette, before attaching the light-trapping fabric, the pile threads are previously bent in a position thereof. The light-trapping fabric is pressed against the first or second wall with a pressing roller, for attaching the second surface to the passage port. An extent of bending the pile threads is enlarged by the pressing roller during the attachment to impart a V-shape to the pile threads.

A container for a strip (12) of light-sensitive material includes an elongated opening for withdrawing the material from the container. Strips (22) of light-locking material are provided on both sides of the opening, the strips being made from a napped and sheared woven fabric (12, 14). The fabric is dyed, dried, napped, sheared and heat set prior to preparation of the strips. A method of producing such a light-locking material is taught which includes steps of passing the woven fabric multiple times through napping and shearing operations to increase the pile density.
摘要:
A container for a web-shaped photosensitive material having a core on which is placed the web-shaped photosensitive material in the form of a roll, a port opening via which the web-shaped photosensitive material is taken out, and light-shielding plushes disposed at the port opening. The light-shielding plush is dyed with a colorant dye having spectral absorption (SQ value) in at least a region of spectral photosensitivity of a red-sensitive layer of the web-shaped photosensitive material. Light fog is prevented.
摘要:
A camera utilizing an image recording medium cartridge provided with a cover for extracting and introducing an image recording medium comprises operation means for operating the cover of the cartridge loaded in the camera; response means for moving the cover of the cartridge in response to the operation of the operation means; and release means for maintaining the operation means in an operable state but causing the response means not to respond to the operation of the operation means in at least either of a situation where the cover of the cartridge is open and a situation where the image recording medium is extracted from the cartridge, or the camera comprises determination means for determinating, after the power supply is turned on, at least either of state of the cover of the cartridge loaded in the camera prior to the turning-on of the power supply and state of the image recording medium, or the camera comprises determination means for directly determinating state of the cover itself of the cartridge loaded in the camera or a member following the movement of the cover.
摘要:
A camera uses a film cartridge having a casing with a spool therein, and a slot formed in the casing. A film is drawn from, and returned into, the casing through the slot. A light-intercepting door is provided along the slot for opening and closing the slot, and a pivotal shaft rotatably mounts the light-intercepting door on the casing. The camera includes first and second motors. The first motor rotates the pivotal shaft to open and close the door, rotates the spool in one direction to advance the film wound on the spool from the film cartridge, and rotates the spool in another direction to rewind the film into the film cartridge. The second motor rotates a film take-up spool provided in the camera to wind the film around the film take-up spool.
摘要:
A camera, an apparatus, or a device applied thereto which uses an image recording medium cartridge having a cover for allowing an image recording medium to come out from or in the image recording medium cartridge, has determination means for determining at least one of a state wherein the cover of the cartridge loaded in the camera or apparatus allows entrance of light into the cartridge and a state wherein the cover of the cartridge clamps the image recording medium, and regulating means for regulating at least one of recording an image on the image recording medium and obtaining a print of an image recorded on the image recording medium in accordance with a determination result of the determination means.
