Abstract

PURPOSE:To make insertion of a film easy by making one wall surface forming an insertion passage freely movable, providing an elastic member to the wall surface and providing such a control means which opens the movable wall surface to a maximum extent when the spool body comes to the prescribed turning position. CONSTITUTION:Three stanchions 3a, 3b, 3c are integrally formed to a substrate 2, and flaps 4a, 4b, 4c are pivotally fitted freely turnably to said substrate 2. On the other hand, cam pins 16a, 16b, 16c are projecting to the bottom surfaces of the movable flaps, and are detained freely slidably in the cam grooves 33 provided to a control member 32 via the hole parts 17 of the substrate 2. Then, when the movable flaps 4a, 4b, 4c which are normally held closed by the effect of a spring 22 rotate the spool body up to the prescribed rotating position, the cam pin 16a is pushed outward by the effect of the cam grooves 33, by which the movable flap 4a is opened outward. An elastic member is provided on the side face or the like of the movable flaps.
