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.
Claims7
An imager apparatus for exposing a film having first and second side edges with recorded images, the apparatus comprising an exposure site and film driving means located at the exposure site for driving film through the exposure site, characterized in that the film driving means comprises at least a pair of cooperating driving wheels acting on opposite faces along only the first side edge of the film, wherein the film is driven along the first side edge and the second side edge of the film is not driven through the exposure site.
An imager apparatus for exposing with recorded images a film having first and second side edges, the apparatus comprising:
- an exposure site;
- a film guide located at the exposure site for guiding the film through the exposure site, comprising first and second lower longitudinal bands, and first and second upper longitudinal bands, wherein the first lower and upper longitudinal bands define a first sliding groove and the second lower and upper longitudinal bands define a second sliding groove, and wherein the first side edge of the film is engaged in the first sliding groove and the second side edge of the film is engaged in the second sliding groove;
- and
- at least one pair of cooperating driving wheels acting on opposite faces and along only the first side edge of the film, wherein the driving wheels engage the first side edge of the film in the first sliding groove to drive the film along the first side edge while the film is not driven along the second side edge through the exposure site.
