Abstract:
A simplified self-developing film unit comprising:a positive receiving sheet, a upper carrier sheet, a lower carrier sheet, a negative photosensitive sheet, a processing fluid supply reservoir at a leading end portion of said film unit, a fluid trap at a trailing end portion of said film unit for collecting excess processing fluid traveling from said fluid supply reservoir and through a processing space; said fluid supply reservoir juxtaposidly disposed between adjacent zones of said upper and lower carrier sheets at said leading end portion of said film unit; said fluid trap juxtaposidly disposed between adjacent zones of said upper and lower carrier sheets at said trailing end portion of said film unit; said upper carrier sheet having a bored out inner region defining a second opening and a framelike upper mating surface; said lower carrier sheet having a bored out inner region defining a first opening and a framelike lower mating surface; one side of said positive receiving sheet being perimeterly disposed with a perimeter area of a first side of said upper carrier sheet in a fluid-tight manner; one side of said negative photosensitive sheet being perimeterly disposed with a perimeter area of a first side of said lower carrier sheet in a fluid-tight manner; and a second side of said upper carrier sheet being perimeterly disposed with a perimeter area of a second side of said lower carrier sheet in a fluid-tight manner to define said processing space wherein said processing fluid may travel from said fluid supply reservoir to said fluid trap.
