Camera with frame shift prevention during exposure

Abstract

A camera comprising a main body part with spaced film supply and film take-up chambers and an exposure opening located between the film supply and take-up chambers and configured for exposing an unexposed film frame, a metering pawl for engaging a film perforation during exposure of the film frame at the exposure opening, and a film winding take-up for moving an exposed frame in a film take-up direction from the exposure opening to the film take-up chamber, is characterized in that the metering pawl is supported to engage a film perforation between the exposure opening and the film supply chamber during exposure of a film frame at the exposure opening, and a tensioning spring urges the metering pawl substantially opposite to the film take-up direction in order to tension a film frame at the exposure opening. Since the film length between the metering pawl and the film winding take-up is longitudinally tensioned, the film frame is similarly tensioned at the exposure opening. Thus, the film tensioning positively acts to prevent frame shift during exposure of the film frame.
