PURPOSE:To allow easy cutting and mounting of a film while magazines are held mounted to a driving part by forming at least either of a shaft and bearings of a stock having elasticity and forming the shaft to the outside diameter larger than the inside diameter of the bearings. CONSTITUTION:The shaft 33 is fixed by pins 34b, 34c provided to hinges 29b, 29c in such a manner that the turning of the shaft is prohibited by the pins. The bore of the circular hole of the hinge 29a in the cap part is formed slightly smaller than the outside diameter of the shaft 33 in a natural state. The bore is expanded by the elasticity of the hinge and the tensile strength of the material of the hinge 29a acts as tightening force when the shaft 33 is inserted into the hole; therefore, the friction force increases extremely even if there is a slight difference between the outside diameter of the shaft 33 and the inside diameter of the circular hole. The hinge 29a is prevented by this friction force from turning around the shaft 33 unless adequate force is applied thereon. The easy cutting and winding of the film are possible in the state of mounting the magazines 21, 22 to the driving part. |
