Abstract
A liquid depositing tip is removably mounted on a tip mounting portion formed on one end of a tip support arm mounted for up-and-down movement. A suction-and-discharge mechanism is operatively connected to the liquid depositing tip by way of the tip support arm to suck sample liquid into the depositing tip and to discharge the sucked sample liquid from the depositing tip onto a chemical assay slide. The quantity of the sample liquid to be sucked into the tip and to be discharged therefrom is controlled by a quantity control mechanism which controls the operation of the suction-and-discharge mechanism. The tip support arm is adapted to be moved up and down between a sucking position in which mounting or removal of the depositing tip is effected, as required, and the sample liquid is sucked into the tip, and a depositing position in which the lower end of the tip is positioned immediately above the reagent layer of a chemical assay slide set to a predetermined position, the sucking position being higher than the depositing position.
