PURPOSE:To improve operability and sealing performance by providing a grip part with an output part which release self-sealing through lever operation. CONSTITUTION:After a film is loaded, a rear cover 4 is rotated around a shaft 8 to be closed, and a grip member 10 and a locking member 12 are rotated in one body around a shaft 9 to engage the projection part 13a of a projection streak 13 in the notch 12a of the locking member 12 by utilizing snap action. This engagement is allowed by moving the locking member 12 away from the grip member 10 against the elastic force of a spring 11. The grip member 10 is utilized as a lever means for the opening of the rear cover 4 equipped with a self-sealing type waterproof seal 6, so the opening of the rear cover 4 is facilitated. Namely, the free end of the grip member is an input part, a shaft 11 is a fulcrum, and the projection part 10a is an output part. |
