Abstract
Abstract An apparatus for aspirating and discharging a specific volume of liquid sample, such as specimen and reagent, has a reaction plate serving a holding function and having a plurality of reaction containers, is provided which is low in cost and compact in design. On one side of a belt applied on two pulleys driven by one driving source an arm for holding a pipet is provided, while a reaction plate holding part is mounted on the other side of the belt (112), thereby constructing an apparatus for aspirating and discharging a liquid sample. When the arm ascends, the holding part descends, and when the arm descends, the holding part ascends. Thus, the arm and holding part are moved mutually in opposite directions by one driving source.
