ABSTRACT:
A film developing system for microimage recording apparatus providing computer output on microfilm utilizing an elongated film strip movable along a film path and employing heat for developing latent image areas formed on the film at an exposure station includes a support for positioning said film strip along the film path at spaced apart locations on opposite sides of a previously exposed latent image area in position ready for developing. A tensioning system is provided for exerting tension on the film strip between said support locations and a developer shoe having an outwardly convex, heated, film contacting surface is adapted to contact the facing surface of the film strip between the supports for developing the latent image area thereon. The developer shoe is mounted for movement between a remote position away from the film path and a film developing position wherein the film strip is tensioned to closer conform to the heated convex surface in intimate contact for a selected time period to develop the latent image area on the film. A heat shield automatically moves between a heat shielding position interposed between the heated surface of the developer shoe and the film strip and a retracted position when the developer shoe is moved into heated contact with the film for developing the image area thereon.
