An apparatus is provided with a movable cartridge casing capable of facilitating film cartridge loading and unloading operations. In a loading operation, the cartridge casing is positioned at a cartridge receiving position outside the body of the apparatus so that the film cartridge can easily be inserted in the cartridge casing, the cartridge casing containing the film cartridge is pushed into the body to an intermediate position where the film spool of the film cartridge is separated from a spool driving shaft, and then the cartridge casing is moved toward the spool driving shaft along a line substantially parallel to the axis of the spool driving shaft to bring the film spool into engagement with the spool driving shaft. In an unloading operation, the cartridge casing is moved away from the spool driving shaft to the intermediate position along the line substantially parallel to the axis of the spool driving shaft to separate the film spool from the spool driving shaft, and then the cartridge casing is moved to the cartridge receiving position outside the body.

An apparatus using a film cartridge in a system that a leading portion of a film contained in a cartridge is thrust to be conveyed from the cartridge, wherein an indicator showing an exposure condition is reset to an original state when an initial loading, which is executed on a film cartridge loading in an apparatus, is not executed normally, and the film is rewound, thus, it indicates "unexposed" when a new film cartridge is loaded. While, when a winding up operation is not executed normally during a photographing, a film is rewound and an indicator showing an exposure condition, is set so as to indicate that the film is exposed. Thus, it prevents from causing a double exposure.

A polyarylene sulfide resin composition comprising a resin composition obtainable by polymerizing 40 to 0.1 part by weight of an unsaturated polyester and 0.01 to 30 parts by weight of a monomer having one or more ethylenic unsaturated bonds in the presence of 100 parts by weight of a composition comprising 1 to 99 wt. % of a polyarylene sulfide resin and 99 to 1 wt. % of a thermoplastic polyester. Since the polyarylene sulfide resin composition of the present invention is in a state wherein the polyarylene sulfide resin and thermoplastic polyester are uniformly mixed, the constituent components are uniformly dispersed and mixed to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Consequently, the composition of the present invention is very superior in that the adhesive property of paint film (paintability), which the conventional polyarylene sulfide resins do not have well, has been improved without a large reduction in the excellent properties of the polyarylene sulfide resin.

摘要:
A polyarylene sulfide resin composition comprising a composition obtainable by a reaction of a polymer composition comprising(A) 100 parts by weight of a polyarylene sulfide resin,(B) 0.1 to 40 parts by weight of a monomer having one or more ethylenic unsaturated bonds and(C) 0 to 40 parts by weight of an unsaturated polyester. In the polyarylene sulfide resin composition of the present invention, a polymer produced by polymerization of the monomer or the monomer and unsaturated polyester, as compared with a resin composition wherein said polymer is simply blended, is in a state wherein it is uniformly mixed with the polyarylene sulfide resin and if necessary a filler. In other words, said polymer is uniformly dispersed in and mixed with the polyarylene sulfide resin to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions. Futher, the amount of said polymer added to the polyarylene sulfide resin is so proper that an excellent-performance resin composition to which an adhesive property of paint film (paintability) has been given, is obtained without a large reduction in the excellent properties of the polyarylene sulfide resin.
