Abstract

A chemical analysis slide cartridge includes a box-like cartridge body in which a plurality of chemical analysis slides are stacked. A slide take-out port is formed in one end of the cartridge body and the chemical analysis slides in the cartridge body are taken out one by one through the take-out port. A pressing member is slidably received in the cartridge body and is adapted to be brought into contact with the stack of the slides on the side remote from the take-out port to push the stack of the slides toward the take-out port. Ratchet teeth are formed on the inner wall of the cartridge body and a claw adapted to be engaged with the ratchet teeth is formed on the pressing member. The ratchet teeth are not formed in a predetermined area near the end of the cartridge body remote from the take-out port so that the claw cannot be engaged with the ratchet teeth when the pressing member is near the end of the cartridge body remote from the take-out port.
