PURPOSE:To easily prevent such an accident that a disk film is wound up without being exposed even by one frame by stopping a lock member which is being displaced forcibly to a lock position beyond the control of a lock member by a stop part provided to the lock member in the middle of displacement before a motor driving main switch is closed. CONSTITUTION:A rear cover lock member 14 has its lock part branch part 14b locked by the 1st bent branch part 18a of the lock member 18 and held at an unlocking position while a back cover 7 is open. When the back cover 7 is closed after a cartridge is loaded in a cartridge storage chamber 8, the lock member 18 is pushed to the front surface of the camera by the lock part 10 of the back cover 7 which is fitted in the lock hole 11 of the camera body 11 and unlocked from the lock member 14, so that the bent branch part 14b is rotated by a spring 16 to the lock position beyond the position of the 2nd bent branch part 18b. On the other hand, when the lock member 14 is to rotate to the lock position regardless of being locked by the branch part 18a while the back cover 7 is open, it is locked by the branch part 18b to inhibit the main switch from being closed, so that the film is not wound up. |
