Abstract
A chemical analysis film cartridge has a box-like cartridge body in which a plurality of chemical analysis films are stacked. The chemical analysis films are taken out one by one through a take-out port formed in one end of the cartridge body. The take-out port has a first opening portion which is opened through a first side wall of the cartridge body and through which one chemical analysis film can be passed and a second opening portion which opened through one end face of the cartridge body. A first engagement portion is formed on the outer surface of the first side wall near the first opening portion and a second engagement portion is formed on the outer surface of a second side wall opposed to the first side wall. A capping member having third and fourth engagement portions is removably mounted on the cartridge body to cover the first and second opening portions of the take-out port with the third and fourth engagement portions respectively engaged with the first and second engagement portions. The capping member is provided with a protruding portion which projects into the cartridge body and pushes inside the chemical analysis films away from the first opening portion.
