Abstract:
PURPOSE: To reduce the number of parts and to make a film pressing block one unit by constituting the film pressing block of a plate, an abutting roller and a compressive torsion spring.
CONSTITUTION: The film pressing block 2 is constituted of the plate 10, the abutting roller 28 and the compressive torsion spring 26. Besides, boss parts 22 and 24 almost coaxial with the shaft parts 12 and 14 of the plate 10 are formed opposite to each other and protruded toward the inside from an aperture part 18 formed at a part corresponding to the almost center of the shaft parts 12 and 14. Then, the spring 26 is fitted to the boss parts 22 and 24 of the plate 10. Since the block 2 assembled in such a way has the roller 28 and the spring 26 fitted to the plate 10 without making them fall, it can be assembled and kept as a single body. Besides, it can be assembled to the back cover of a camera layer.
