Abstract
An imager apparatus for exposing a film with recorded images includes an exposure site, a primary film path along which unexposed films are fed to the exposure site, a secondary film path along which exposed films are taken away from the exposure site, and a film driver at the exposure site. The film driver drives films between the primary and the secondary film paths. The film driver includes at least a pair of cooperating driving wheels on opposite faces along only one side edge of the film to eliminate transmission rods.
