Abstract
A lens-fitted photo film unit includes a main body preloaded with photo film. A front cover covers a front of the main body. A rear cover covers a rear of the main body. A retainer mechanism has a retainer claw and a receiver portion engaged with each other, for connecting rear walls of the main body and the rear cover. An opening is formed in the rear cover, for uncovering at least a portion of the retainer claw or the receiver portion. For disassembly, a release claw is inserted into the opening by setting the lens-fitted photo film unit in a cover separating station with the rear cover directed downwards. The release claw is disposed to protrude upwards in the cover separating station. The release claw is shifted relative to the opening, to disengage the retainer claw from the receiver portion by flexing the retainer claw away therefrom. After disengaging the retainer claw from the receiver portion, the main body is moved away from the rear cover.
