Abstract
The disclosed display device has a number of display elements arranged in a row and successively driven so that a display film transport is presented as if the border of one film frame runs from one of two spools marks to the other in the same direction in which the film is actually being transported across the exposure gate. The display device also indicates whether or not a film cartridge is loaded in the camera.
