摘要： PURPOSE: To provide a photographic film cartridge having an excellent wearing aptitude and high durability and feeding capacity by selecting resin material for disk being a component for photographic film cartridge. CONSTITUTION: A cartridge main body 2 is composed of upper and lower cases 2a and 2b made of plastic respectively. A spool 4 is freely turnably housed in the cartridge main body 2 and a photographic film is taken up in a roll shape on the spool 4. The disks 6a and 6b are attached to both ends of the spool 4, a lip 11 is formed on the outer peripheries of the disks 6a and 6b to prevent the photographic film 9 in the roll shape from being loosened and the disks 6a and 6b hold both end parts of the photographic film 9 so as to wrap them. As the molding material of the disks 6a and 6b, mixed resin obtained in such a manner that when the mixture of PS resin and PPE resin in the ratio of 3:7 is assumed to be 100 pts, elastomer in the range of 6-19 pts. is mixed to the mixture of the PS resin and the PPE resin, is used.

摘要： PROBLEM TO BE SOLVED: To decorate the surface of a frame embracing the periphery of the print surface of a positive image without considerably modifying a conventional instant film manufacturing process.
SOLUTION: White plain first to third color layers 30a-30c are disposed by gravure printing. Fourth color layers 37, fifth color layers 38 and sixth color layers 39 different from one another in color are disposed by gravure printing on the third color layer 30c to give close print with a repetitive pattern. Silica and/or resin power is added to a seventh color layer 30d and titanium dioxide is removed. Eighth color layers 36 are further disposed on the seventh color layer 30d. Eight-color printing is enabled at a time with a printing machine capable of printing up to eight colors in total.

摘要： PROBLEM TO BE SOLVED: To obtain a pressure-sensitive adhesive tape which, even when stored or transported for a long time in a state stuck to the end of a photographic material roll, does not adversely affect the photographic performances of the roll by applying a pressure-sensitive adhesive composition based on a rubbery pressure-sensitive adhesive component and further containing a phenolic antioxidant to the surface of a sheety support in a specified coating weight. SOLUTION: A pressure-sensitive adhesive composition prepared by using a rubbery pressure-sensitive adhesive component, desirably, a styrene/butadiene rubber, as the principal component and a phenolic antioxidant and, desirably containing rosin and lanolin is applied to the surface of a sheety support (e.g. polyvinyl chloride film) in a coating amount of 10-20 g/m . The phenolic antioxidant is desirably 2,4-dimethyl-6-t-butylphenol, 2,6-di-t-butyl-p-cresol, 4- hydroxymethyl-2,6-di-t-butylphenol, 2,6-t-butyl-α-dimethylamino-p-cresol, or the like.

摘要： PROBLEM TO BE SOLVED: To provide a film pack housing package and a camera capable of easily and speedily loading a film unit, reduced in waste, low in cost and hardly causing pressure fogging and static fogging in the film unit. SOLUTION: When the film pack housing package 1 is inserted in a preliminary chamber 52, supporting members 62 and 63 are inserted in a space at the side part of a film pack in a box member 5 and a take-up shaft 3 is caught by the tip parts thereof. Thereafter, when the box member 5 is pulled out from the chamber 52, the film pack 2 is left in the chamber 52. When a back cover 53 is closed, the chamber 52 is housed in a film loading chamber and a gear 10 is meshed with the gear of a development roller at the same time. When the development roller is rotated by depressing a shutter botton, the shaft 3 is rotated and a sheet member 12a is taken up by the shaft 3. Then, the pack 2 is disassembled and the film unit is set in the film loading chamber.

摘要： PROBLEM TO BE SOLVED: To prevent such problems that bar codes or numbers thermally transferred to adhesive labels are easily worn or peeled, by incorporating a resin and wax to an ink layer of an ink ribbon and controlling the weight ratio of wax/resin to a specified range. SOLUTION: The ink ribbon 83 consists of a base layer 93, a release layer 92, and an ink layer 91. By heating the ribbon through the base layer 93 by a heat generating element array 88, the ink layer 91 is molten only in the heated part and thermally transferred from the release layer 92 to an adhesive label 8. The component of the ink layer 91 consists of a mixture of pigment, wax and resin. The resin is the matrix to fix and hold the pigment on the adhesive label 8 and the wax is added to obtain proper transfer property. The wax added has 50 to 100 deg.C softening point or melting point. The weight ratio of the wax in the ink layer 91 to resin is controlled to (0.05 to 0.2):1.

摘要： PROBLEM TO BE SOLVED: To reduce the cost of a film cartridge by making it possible to use an inexpensive light shielding member. SOLUTION: Polyethylene arom. decarboxylate-based polyester which has 105 to 50μm thickness and 50 to 200 deg.C glass transition temp. and is subjected to a heat treatment for 0.5 to 1500 hours at a temp. above 40 deg.C and below the glass transition temp. before the application of a primer coating layer or after the application of the primer coating layer before the application of the emulsion is used as the base of a photographic film 12. A raised woven fabric or raised knitted fabric or non-woven fabric having 0.5 to 1.5mm length in raised parts is used as the material of the light shielding member 15 to be fixed to the inside wall of a port part 14. For example, the raised woven fabric formed by using 6 nylon yarn of 120 denier/30 filaments and a twist number of 600 times/m as warp and 66 nylon double ply yarn of 100 denier/48 filaments and a twist number of 300 times/m as weft and weaving the warp and the weft to 5-sheet satin of weft satin, then raising the fabric by raising the warp with a raising machine is used and the length of the fluff is specified to 1.4mm.

摘要： PURPOSE: To prevent the defective die reproducibility, etc., by using a die provided with plural vacuum holes at the corner reproducing the outer ridge of a flange in vacuum forming. CONSTITUTION: A thin discoid flange is fixed to both ends of a spool shaft as the parts of a photographic film cartridge. The flange is formed by vacuum- forming a thermoplastic resin sheet 40. A female die 47 provided with plural vacuum holes 70 at the corners 63 and 67 reproducing the outer corners 62 and 66 of the flange is used in the vacuum forming. The diameter of the hole 70 is controlled to 0.2-0.5mm, the radius of curvature of the corners 63 and 67 provided with the vacuum holes 70 among the corners 61, 63, 65 and 67 of the die 47 is controlled to 0.2-0.5mm, and the radius of curvature of the corners 61 and 65 not provided with the hole 70 is controlled to 0.1-0.5mm.

摘要： PURPOSE: To provide a bar code label for a photographic film cartridge whose bar code can be surely read and which is surely attached. CONSTITUTION: As to this bar code label; a transparent base layer 20, an ink layer 22 printed by the pattern of a bar 16, and a reflection layer 21 by means of a metallic thin film coating the layer 20 are formed, and the bar code label is stuck to a bar code board through an adhesive layer 23. The ink layer 22 is obtained by printing in black ink to which mat agent is added and its surface is roughed. The reflection layer 21 is exposed to an upper surface from the part where the layer 22 does not exist, so that the layer 21 becomes the pattern of a space 17. When a photosensor 38 on a camera side is opposed to a bar 16, infrared light is absorbed by the layer 22, and also the part of the infrared light is diffused and reflected by the roughed surface, so that only extremely weak regularly reflected light is made incident on a photodetector 37. When the photosensor 38 is opposed to the space 17, the infrared light is positively reflected by the mirror operation of the layer 21, and is made incident on the photodetector 37.
