Abstract

A photographic camera has a housing provided with a film loading chamber, a film storage chamber and a film window. An arrangement is provided for transporting unexposed film from the loading chamber to the storage chamber and for subsequently transporting it intermittently past the film window for exposure and back into the loading chamber. This arrangement includes a direction-reversible film transporting motor, an operating member which causes the motor to rotate in one direction in which film is transported from the loading chamber into the storage chamber, and a camera actuating member which causes the motor to rotate in an opposite direction in which the film is intermittently transported from the storage chamber past the film window into the loading chamber.
