Abstract
An optical printer module has a film pack compartment that stores a film pack which stores an instant print film in a frame composed of a main frame, a subframe and a cover. The frame contains a claw mechanism and a spread mechanism that includes a pair of spread rollers. The claw mechanism feeds the instant print film out of the film pack while the instant print film is being exposed, and the spread rollers pinch the exposed instant print film fed out of the film pack by the claw mechanism to develop the exposed instant print film and feed the developed instant print film from the optical printer module. The whole surface of the frame shades the film, except for an opening for the film pack.
