PURPOSE:To enable sure and easy detaining by specifying the ratio between the inside radius of a film winding chamber and the radius of a core existing in the winding chamber. CONSTITUTION:This magazine consists of a film supplying chamber 3 contg. a film 1 wound together with a rear plate 2, the film winding chamber 6 having a pawl 4 for stopping the film and the winding core 5 and a connecting bridge part 7 for connecting the two chambers 3, 6. The magazine is so formed that the ratio between the inside radius A of the film winding chamber 6 and the radius B of the core 5 existing in the winding chamber 6 attains >=1:0.73. The margin between the terminal part of the film 1 and the wall of the winding chamber 6 is thereby decreased when the film 1 is taken up near to the terminal thereof. The film detaining hole is thus surely engaged with the detaining pawl 4 and is prevented from being pulled off. |
