PURPOSE:To facilitate the camera operation and to prevent the occurrence of erroneous film advancing or the like even if the back cover is opened erroneously in course of photography, by charging a mode switching mechanism for the end of continuous advancing by a patrone detecting means. CONSTITUTION:A patrone detecting lever 76 which switches the mode automatically from the advancing mode to the mode for rewinding one frame at every shutter operation after a film is advanced continuously detects a loaded patrone 35 to move to the left. Thus, the lever 76 is charged by a spring 77 to switch the mode automatically to the continuous film advancing mode and the constant length rewinding mode for the photographic preparation surely with an easy operation. Even if the back cover is opened erroneously in course of photography, the occurrence of erroneous operations such as film advancing is prevented. |
