Abstract

Disclosed is a lens-fitted photographic film unit containing a roll of unexposed photographic film. The lens-fitted photo film unit uses a specific battery of a different size or shape from conventional standardized batteries. A hollow protrusion is formed in a battery holding room. A hollow of the hollow protrusion joins with a dark room for the photographic film. If the hollow protrusion is cut away with the intention to put a conventional battery in the battery holding room, the light-tightness of the dark room is destroyed. When a cartridge chamber bottom lid is opened to remove a film cartridge, an interconnection lever transmits the opening movement of the lid to a sliding plate. Then the sliding plate turns a charge switch of a flash circuit ON, and locks the charge switch in the ON position.

Description

technical field [0001] The present application relates to a lens-fitted photo film unit which can only use a special battery as its power source, and more particularly to a lens-fitted photo film unit having means for preventing illegal reuse of its unit main body. The invention also relates to special batteries for lens-fitted photo film units. Background technique [0002] A lens-fitted photo film unit is known as a unit preloaded with a strip of unexposed photo film ready for shooting at the time of purchase. After all the pictures have been taken, the photographic film unit with the lens attached is taken to a photofinishing shop, where the exposed photographic film is removed and processed for development and printing. After the exposed photo film is taken out of the lab, the used lens-fitted photo film unit is collected by the manufacturer of the lens-fitted photo film unit for reuse of some components and for material recovery of some components. [0003] Selected m...
