CASSETTE USED FOR IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the preservation of a photosensitive recording medium housed in a cassette and to make the constitution of the cassette compact. SOLUTION: The cassette 2 which can be freely attached to/detached from the main body case of this device is provided with a 1st roll part 6 for housing the unexposed photosensitive recording medium 3 by winding it in a roll state and a 2nd roll part 8 for housing a double coated adhesive tape 7 superposed on the back surface of the medium 3 on a carrying downstream side from a developing part. An exposure part 10 where the medium 3 drawn out from the 1st roll part 6 is exposed by an exposure means is provided with shading parts 16 and 17 made of felt which slide on both surfaces of the carried medium 3 and a shutter means 15 having flexibility. The shutter means 15 allows the exposure means to be inserted in the exposure part 10 and shades the exposure part 10 from light by pulling out the exposure means.
