PURPOSE:To facilitate the loading and unloading of a film cassette by dividing a spool radially into two, allowing its 1st member to move freely in thrust directions and engage with the 2nd member in rotational directions, and rotating them in one body. CONSTITUTION:The cassette body 1 is provided with a cylinder part 1 which forms a film supply part 3 and a cylinder part which forms a film take-up part 4 together with a bridge 2 in one body. The spool 20 of the film take-up part 4 is composed of the 1st and the 2nd members 21 and 22 by dividing a columnar body radially into two, and both members 21 and 22 are movable in thrust directions, but engage with each other in rotatinal directions to rotate in one body. When the 1st member 21 moves up until its engagement pawl part 29 engages with the pawl part of the film winding shaft 46, the rotation of the film winding shaft 46 is transmitted to the 1st member 21 and further transmitted to the 2nd member 22, so the film 5 in the film supply part 3 is taken up by the 2nd member 22. |
