Abstract
A casing has a flat plate for being irradiated with a radiation from an external source, a plurality of metal plates disposed on edges of inner surfaces of ends of the flat plate, and a plurality of resin frames integrally molded on the ends of the flat plate in embedding relation to the metal plates. It is possible to produce a high-quality radiation cassette having a simple structure which prevents the resin frames integrally molded on the flat plate from being deformed, according to a simple process.
Claims15
A radiation cassette comprising:
- a casing for storing a radiation image recording medium therein;
- and
- a light shielding plate for holding the radiation image recording medium in a light-shielded condition, said light shielding plate having a lid openably and closably mounted on at least a portion of said casing;
- said casing comprising:
- a flat plate for being irradiated with a radiation from an external source;
- a plurality of metal plates disposed on edges of inner surfaces of ends of said flat plate;
- and
- a plurality of resin frames integrally molded on the ends of said flat plate in embedding relation to said metal plates.
A radiation cassette comprising:
- a casing for storing a radiation image recording medium therein;
- and
- a light shielding plate for holding the radiation image recording medium in a light-shielded condition, said light shielding plate having a lid openably and closably mounted on at least a portion of said casing;
- said casing comprising:
- a flat plate for being irradiated with a radiation from an external source;
- said flat plate being only a three-layer structure including two carbon layers providing opposite surfaces and an insulating layer interposed between said carbon layers, said insulating layer having an insulating strength of at least 5 kV.
A method of manufacturing a radiation cassette including a casing for storing a radiation image recording medium therein, and a light shielding plate for holding the radiation image recording medium in a light-shielded condition, said light shielding plate having a lid openably and closably mounted on at least a portion of said casing, said method comprising the steps of:
- placing metal plates on edges of inner surfaces of ends of a flat plate for being irradiated with a radiation from an external source;
- integrally molding a plurality of resin frames on the ends of said flat plate in embedding relation to said metal plates, thus producing said flat plate.
