PURPOSE:To facilitate operation and to reduce the size of a film cassette by composing a spool of a film take-up member and an engagement member which engages the film winding shaft of a camera, and engaging the engagement member with the film take-up member when the engagement member is pushed up to rotate them in one body. CONSTITUTION:While the opening/closing cover 9 of the camera body 6 is open, the cassette body 1 is loaded at a specific position of a cassette storage chamber 7 and then the opening/closing cover 9 is closed. Then, a lock lever 57 rotates clockwise to unlock a slide plate 45 from the engagement member 61, and the slide plate 45 slides upward by the restoring force of a spring 50. The engagement member 21 moves up through a press-up pin 51 by the restoring force to engage the pawl part 30 of the engagement member 21 with the pawl part 53 of the film winding shaft 52. Therefore, the rotation of the film winding shaft 52 is transmitted to the engagement member 21 through the pawl part 30 and further transmitted to the film take-up member 22 through engagement pawls 37 and 38 to take up a film. |
