Abstract

In a film cassette (1), the film tube (5) can be rotated independently of one pair of co-axes (51,53), two discs (51,53) with an outer rim, each rim forming a ring. (59,61) which prevents the coexistence of the coexistence of the outermost conductor (47) of the film reel (37) wrapped on the spool (23) from the spring spring into contact with the film cassette shell ( 3) When the spool (23) was initially rotated, the plate (51,53) was able to remain largely stationary, and the film reel (37), since its inner end (39) was fixed to the Core tube Will loosen Radial To make sure There is no relationship in Sliding between the coexistence of the outer conductor (47) and the periphery (59,61), then the rotation of the spool (23) with the turntable (51,53) and the dispenser. The stationary internally (65,67) deflects the continuation (59,61) of the rim (59,61) to the width of the resulting film along the axial size, allowing the notch response portion. The coexistence of the leading outermost roll (47) leaves the radial boundary of the rim. The stationary internal lead (73,75) sends the free end of the trace. The coexisting roll of the outermost guide (47) to the opening of the film canister (25) is pushing the sufficient film. Held by the spool (23) as it has been rotated To string parts, take the film (43) along the path as specified. Coming out of the opening of the film canister (25) to the outside of the Film cassette shell (3)

Claims (1)

1. Film cassette (1) in which the outermost coils (47) of the film reel (37) are coiled approximately the spool (23) is forced along the radial edge of each ring (59). , 61) of a pair of discs (51,53) located on the spool to prevent such outermost coils in contact with the inner wall (63) of the film cassette shell (3) ends. In (39) of the roll (37) was tensioned to the spool (23) and the disc (51,53) could be rotated in The unwinding direction (u) to pass the leading portion of the film roll:
