ABSTRACT:
A self-processing type photographic film unit having an improved trap structure for collecting surplus processing solution used in developing the unit. The trap structure includes a partition member dividing a pouch-shaped hollow interior formed by a trap cover member into upper and lower chambers and forming a U-shaped flow path which communicates with gas discharging through-holes formed in the upper surface of the trap cover member. First and second spacer members are provided on the lower and upper surfaces of the partition member with the first and second spacer members permitting the U-shaped flow path to pass gas in the unit while catching surplus processing solution.
