PURPOSE:To facilitate loading and removing of a film by providing a tapered part in at least one end part of a pawl-like member, and quiding a projecting part from the side part of a box-like member to release the detention of the pawl-like member. CONSTITUTION:The projecting end of a lever 58 is formed like a pawl so as to be hooked to a locking pawl 57, thus said end has a function of latching a casing 52 and a cover part 54. Both end parts of the lever 58 are tapered 60 so as to permit entry of projecting pieces from both sides. Therefore if the operator presses the lever 58 in the direction opposite from an arrow by inserting his finger into the clearance 61 on the opening part side of the casing 52 and the part 54, the hatching between the casing 52 and the part 54 is released. Since the clearances on both sides of the clearance 61 are tapered so as to expand toward the outer side by tapered parts 60, it is possible to release the latching by inserting projecting pieces therein from the side parts. |
