Abstract: A method for manufacturing a hologram optical substrate having a hologram element includes: a cutting process that employs a laminate sheet having a pair of protective sheets with a hologram photosensitive sheet peelably interposed therebetween, and makes a cut to a depth for cutting the hologram photosensitive sheet, the cut corresponding to a hologram element forming section; a first peeling process that peels the protective sheet having the cut; a sticking process that sticks a hologram photosensitive material of the hologram element forming section to an inclined surface of the optical substrate, with the hologram photosensitive material adhered to the other protective sheet; a second peeling process that peels the other protective sheet; an exposure process that exposes the hologram photosensitive material to a laser beam after the second peeling process; and a developing process that develops the exposed hologram photosensitive material so as to form a hologram element.

Abstract: In a container for storing plural different kinds of photosensitive material processing agents provided with a first storing room having a first opening; a second storing room having a second opening; a third storing room having a third opening; a first flange section to enclose the periphery of the first opening; a second flange section to enclose the periphery of both the second opening and the third opening; and a cover member to cover the first opening, the second opening and the third opening, the second storing room is located between the first storing room and the third storing room and a first distance between the first storing room and the second storing room and is made larger than a second distance between the second storing room and the third storing room.

Abstract: The single-use camera has a main body in which is housed the film cartridge and around which a cover member is formed. On the main body of the camera is a closure and a spring which are used to close the light-shield cover in the film gate of the cartridge when the cover is opened to remove the film cartridge.

Abstract: A single-use camera which is loaded with a film cartridge having a light-shielding cover on a film gate thereof. The single-use camera includes: a cover for covering the film cartridge when the cover is at its closed position, a closing member for closing the light-shielding cover of the film cartridge, a stopper for keeping the cover member at the closed position, and a stopper release for releasing the stopper so as to allow the cover to be open while the light-shielding cover is being closed by the closing member.

Abstract: A manufacturing method forms flanges for use in a film cartridge which are made of resin. Each flange is made of the resin by an injection molding process. Gates to cavities provided in a mold are located such that residual portions of solidified resin at the gates, remaining after the injection molding process has been completed, do not come into contact with a film in the cartridge as the film is moved into and out of the cartridge.

Abstract: A photographic roll film cartridge in which a roll film is stored in an initial packaged condition before being used for photographing. In the initial packaged condition, the leading edge portion of the roll film protrudes out of the cartridge by a length of 10 mm to 25 mm.

Abstract: A film cartridge container which can accommodate two film cartridges with short film tongues projecting straight from the cartridges. The film cartridge container has devices for fixing the film cartridges in the container and for attaching another film cartridge container by lid and bottom so that many containers can be stack for display.

Abstract: A tape cassette for use in a recording apparatus with a lid lock to lock a front lid of the tape cassette in a closed position. The lid lock includes a fixing portion which fixes the lid lock to the cassette body, and a locking portion with a lock claw which engages the front lid to lock the front lid in the closed position. A reinforcing member formed of a resilient material extends between a support portion and a front leg portion of the lock member to bias the front leg portion of the lock member in a frontal direction toward a locking position. The lock claw locks and releases the front lid by movement caused by the deformation of the lid lock.

Abstract: A magazine for a roll-type of photosensitive material having: an inner holder including a back plate made of paper; side plates made of paper connected with both sides of the back plate; supporting members each composed of plural accumulated disks and made of paper for supporting both ends of a spool around which the photosensitive material is wound; and a lightproof box made of paper to cover the inner holder. A slit through which the photosensitive material is pulled out is formed by a folded portion of the back plate and a lid portion of the lightproof box. A lightproofing material is provided to the folded portion of the back plate and the lid portion of the lightproof box at the slit. The supporting members are pivotally held by the side plates through a metallic or a synthetic resin shaft.

Abstract: A film magazine forming apparatus forms a sheet having printing on a side thereof into an almost cylindrical shape. The film magazine formed into the almost cylindrical shape has separated lip portions for enabling a film to mvoe therethrough. The lip portions have a soft yarn mounted thereon. Transport apparatus transports the sheet to forming means including a core mold, an upper mold, and first and second side molds which form the sheet into an almost cylindrical shape with the printing on the side of the sheet forming an outer cylindrical surface of the almost cylindrical sheet. Transport apparatus transports the sheet with the printed side of the sheet being out of contact with the transport apparatus to prevent damage to the printing on the sheet. In addition, the core mold is used as a guide for transporting the almost cylindrical shape sheet to another operating position. A claw can be mounted on the core mold for transporting the thus formed almost cylindrical shape to another operational position.

Abstract: A spool for winding a photographic roll of film in a camera. The spool includes a shaft having a slit formed by opposed walls one of which has a protrusion extending into the slit and positioned between two ribs of the other wall. The protrusion is received in a perforation of the film tongue to wind the film when the spool is turned in a winding direction. When the film is unwound, the film tongue smoothly and reliably slips out of the slit as the perforation wall slides down an angled wall of the protrusion so that the film is released from the spool.

Abstract: The present invention relates to a cartridge for packaging a roll film. The cartridge has a film outlet that is composed of upper and lower lips, each lip has a light-shielding ribbon attached to the inside thereof. Both extended side edge portions of the ribbon attached to the lower lip are slightly bent downwardly. Both extended side portions of the ribbon attached to the upper lip are also bent downwardly at a slightly larger angle than that of the lower lip. Consequently both side edge portions of both upper and lower lips overlap in a more complete manner or are more positively joined together.

Abstract: The invention provides a spool for winding a photographic roll film. The spool has a bar-shaped spool core which is slitted to lengthwise direction to form a slit for inserting a tongue-shaped end of the film having a through hole. On an inside wall of the slit, there is provided a catch claw capable of engaging the through hole. On another inside wall opposite to the above inside wall, there is provided a pressing rib for pressing and guiding the tongue-shaped end to the catch claw. A part of the outer surface of the spool core, adjoining to the inside wall of the slit in which is disposed the pressing rib, is shaped to serve as a film contact surface. The tip surface of the pressing rib and the film contact surface both jointly form a continuous shape of a circular arc.
