Abstract
Apparatus in a photographic camera for moving an exposed section of a filmstrip loaded into a camera from the exposure gate to a curl-developing area located along the film transport path after a predetermined period of camera inactivity as measured by an included timing circuit so as to prevent the onset of a reverse curl. According to the invention, the apparatus includes a control mechanism for automatically advancing a succeeding unexposed film portion to the exposure gate upon reactivation of the camera.
Claims5
A photographic camera wherein successive unexposed sections of a filmstrip are exposed, is characterized by:
- time determining means for determining a predetermined period of camera inactivity;
- and
- film moving means for moving an unexposed film section from a curl-developing area to a curl-defeating area after a predetermined period of camera inactivity as determined by said time determining means.
