Title:
CASSETTE FOR RADIATION
Document Type and Number:
WIPO Patent Application WO/1990/009620
Kind Code:
A1
Abstract:
This invention relates to a cassette for radiation which is used for holding therein an X-ray sheet film or the like. The frame (13) of this cassette consists of corner members (20) corresponding to the corners of a front sheet and straight members (30) connected to the corner members (20) and corresponding to the sides of the front sheet. Each corner member (20) is provided with an integrally molded substantially L-shaped main body portion (21), fitting projections (22) projecting from both ends of the main body portion (21) and fitting pins (23). Fitting recesses (31, 32) for accepting the fitting projections (22) and the fitting pins (23) of the corner member (20) are formed in the straight member (30) and front sheet fitting grooves (24, 33) for receiving the edge of the front sheet (12) are formed continuously around the inner peripheries of the corner members (20) and straight members (30). In this manner the production cost of the cassette for radiation can be reduced and its strength can be improved.
