ABSTRACT:
In a light-tight cassette for a roll of light-sensitive strip material comprising a body having a slot for extending the light-sensitive strip material and end panels closing both end openings of the body and supporting said roll, the improvement which comprises at least one of the end panels having a rotary core to which the core of the roll is fixed, a bearing means which rotatably supports the rotary core and a fixing means to fix the rotary core to the end panel releasably.
In the light-tight cassette of the invention, since the core of the light-sensitive strip material is fixed to an end panel through the rotary core by the fixing means, loosening of the roll of the light-sensitive strip material does not occur by the shaking during transportation or the like. Therefore, the problems in quality such as the degradation of surface quality do not occur. Since the fixation is readily released by pulling the light-sensitive strip material, it may easily be extended at the time of use.
