ABSTRACT:
The present patent application discloses a blank film advance control device for a camera, in which when the film loading cover is closed, the film is automatically advanced a prescribed number of blank frames. The device is provided with means for memorizing the fact that the advancing of the blank frames has completed and means for coordinating the memorizing means with the film loading cover to restore the memorizing state of the memory means at least until the film is rewound. With this, even if the film loading cover is accidentally opened and closed again after the end of the blank film advance, the camera is prevented from performing faulty operations, for example, a second cycle of blank film advance. Instead, it carries out a proper different operation from the first cycle of blank film advance which took place after the film loading cover was closed for the first time.
