ABSTRACT:
An improved self-developing film unit comprising: processing fluid supply means including a rupturable reservoir of processing fluid at a leading end portion of the unit; image recording means of the self-developing type including first and second overlying layers one of which is exposable to form a latent photographic image, and spacer means connected to and between said first and second layers for providing a processing space therebetween for allowing processing fluid to pass therethrough; fluid trap means at a trailing end portion of the film unit for collecting excess processing fluid traveling through said processing space; first fluid-tight coupling means including a fluid passage for fluidically coupling said reservoir to a leading end of said processing space for allowing processing fluid from a ruptured reservoir to be introduced into said processing space and initiate processing of the latent image; and, second fluid-tight coupling means including a fluid passage for fluidically coupling a trailing end of said processing space with said trap means for allowing processing fluid to enter into said trap means; said first coupling means having one end portion sealably secured to an exterior surface of said reservoir and a second end portion sealably secured to an exterior surface of a leading end portion of said image recording means; and, said second coupling means having an end portion sealably secured to and about the trailing end portion of said image recording means and an opposite end portion sealably secured to an exterior surface of said trap means.
