摘要： 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.

摘要： A chemical analysis element cartridge includes a box-like cartridge body in which a plurality of chemical analysis elements are stacked and are taken out through an element take-out port formed at one end of the cartridge body. A pressing member is slidably received in the cartridge body and is brought into contact with the stack of the elements on the side remote from the element take-out port to push the stack of the elements toward the element take-out port. The cartridge body is provided at least in one side wall thereof with a slit which extends in the direction of stack of the elements and the pressing member is provided with an external force receiving portion which is laterally interlocked with an urging member disposed outside the cartridge body through the slit and receives a force for urging the pressing member toward the element take-out port from the urging member. The pressing member is interlocked with an engagement member so that the pressing member and the engagement member are moved toward the element take-out port together with each other when the force from the urging member is acting on the pressing member and the engagement member permits the pressing member to be displaced away from the element take-out port relative to the engagement member when the force from the urging member is released.

摘要： A device in a liquid development system to prevent soiling of support rollers for an imaging member wherein the support rollers previously soiled the back surface of the imaging member. The invention comprises insulating the support rollers and applying a developing voltage only when the imaging member has been inserted between the support rollers and another set of rollers which also serve as development electrodes so that voltage is not applied on a given roller pair not carrying the imaging member, thus developer material is not induced to flow on roller pairs not bearing the imaging member.

摘要： The invention provides a blood filter cartridge which is made so that the filtrate discharged from the filtrate outlet is not drawn back to the inside of the filtering chamber. The blood filter cartridge includes a blood filtering material, a holder containing the blood filtering material and having a blood inlet and a filtrate outlet, and a filtrate receiver which receives the filtrate discharged from the filtrate outlet. The blood filter catridge is provided with a means for preventing the filtrate in the filtrate receiver from returning to inside of the holder upon finishing filtration. Such means include the following: removing opposite faces around the filtrate outlet, making length of lower end of the filtrate outlet 0.8 mm or more, smoothing surface around the filtrate outlet, and forming surface around the filtrate outlet by a material having a small surface energy.
