Abstract:
A cartridge (2) contains a recording disk (4) having photosensitivity. The cartridge comprises a cartridge shell (11), a light shielding plate (12) and a shutter (13). The cartridge shell has an internal opening (18) for exposing a central portion and a recording surface of the recording disk to the outside. The light shielding plate is attached to an outer side of the cartridge shell and has an external opening (14) confronting the internal opening. The shutter is slidably disposed between the cartridge shell and the light shielding plate to open and close the internal opening. A lock mechanism locks the shutter in a closed position. For releasing the lock mechanism, it is necessary to slide a first lock member (63), which is exposed through a cavity (72), in a state that a second lock member (64) projecting into a groove (7) is pushed into the cartridge shell.
Abstract:
A cartridge is composed of a cartridge body and a shutter. A hologram recording disk is rotatably contained in a disk recess formed in the cartridge body. The shutter comprises upper and lower shutter plates between which the cartridge body is interposed. The shutter opens and closes openings formed in both surfaces of the cartridge body. When the shutter is kept in a closed position where the openings are closed, the edges of the shutter are inserted into slits formed around the opening. Further, a groove is formed at an end portion of the shutter. Into the groove, a ridge formed on the cartridge body is inserted.
Abstract:
A cartridge (2) is composed of a lower shell (30), an upper shell (31), a shutter 10 and a lock mechanism (11). A hologram recording disk (4) is rotatably contained in a disk recess (3) of a cartridge body (25) formed by joining the lower shell (30) and the upper shell (31). Inner surfaces of the lower shell (30) and the upper shell (31) are provided with a first concave portion (34), a second concave portion (35), a first convex portion (42) and a second convex portion (43). When the lower shell (30) and the upper shell (31) are joined, the concave portions and the convex portions engage to form a labyrinth-like light-shielding structure. In virtue of this, light and dust are prevented from entering through a gap residing between the lower shell (30) and the upper shell (31).

Abstract:
An instant film pack includes a plurality of instant photo films. A case contains the instant photo films being stacked. An exit slot is formed in the case, for exiting the instant photo films to an outside of the case one after another. A claw path opening is formed in the case, for receiving insertion of an advancing claw mechanism for advancing the instant photo films by one photo film to move to the exit slot. A thrust preventing flap is disposed on an inside of the exit slot, for closing the exit slot at the middle, to prevent the instant photo films from coming through the exit slot. Furthermore, a light shielding sheet of aluminum foil closes the claw path opening in a light-tight manner, and is released to open the claw path opening upon advance of the advancing claw mechanism.
Abstract:
A cassette for containing photographic film has a spool which is provided with retaining claws for retaining a trailer of the photographic film. A cassette port communicates the spool chamber to the outside. To load the photographic film into a cassette, a loading apparatus picks up the trailer with an inserter jig. The inserter jig is passed through the passage port, and is brought to the spool so as to insert the trailer into the cassette shell. The trailer is retained on the spool with the retaining claws. The inserter jig is then drawn out of the cassette shell. Then the spool is rotated in order to wind the photographic film around the spool, fully into the cassette shell. To remove exposed photographic film from such a cassette, the photographic film is drawn and unwound. A separator jig, as passed through the passage port, is brought to the spool. The trailer is released from retention on the retaining claws by use of the separator jig. Then the photographic film is drawn out so as to separate the trailer from the spool.
Abstract:
A film pack is comprised of a case body and plural film units stacked inside the case body. An exposure opening is formed in the front wall of the film pack, and an ejection slit for advancing the film unit out of the film pack is formed in the upper wall. In the ejection slit, front and rear slit edges are confronted with each other. Engaging ridges are provided on the middle of the front slit edge. When external force is applied to the front wall, the engaging ridges press an engaged portion, which is provided in the middle of the rear slit edge. Then, the engaged portion is depressed and engaged with the engaging ridges. Thereby, it is possible to prevent further deformation of the front wall, which causes rupture of a processing fluid pod in the film unit.
Abstract:
A case body containing instant photo films includes an exit slot for feeding out one instant photo film after another, and a claw path opening for allowing entry of a claw member ejecting the instant photo films. A pair of thrust preventing flaps is disposed inside the exit slot, for closing the lateral ends of the exit slot to prevent the instant photo film thrusting out. The claw path opening is closed by a light shielding plate and a light shielding skirt, which compose a light shielding member. The light shielding plate is moved to an open position by the claw member in the first advancing operation, and is moved to a full-open position in the second advancing operation.
