Patent ID: 7892490

Claim:
A semiautomatic operating device for a microchip on which at least one micro-channel with a reagent inlet is formed, comprising: a base having an accommodating unit which accommodates the microchip; a slider with injection inlets corresponding to the reagent inlets that reciprocally move parallel to the base; and a slider moving unit which selectively moves the slider to a first location at which the microchip is opened, after the injection inlet of the slider and the reagent inlet are aligned, and to a second location where the microchip is sealed by a bottom surface of the slider covering the reagent inlet, wherein the slider moving unit comprises: a shuttle, one end of which receives an external force and the other end of which is equipped with the slider so that the slider can slide back and forth from the first location to the second location when the shuttle slides back and forth with respect to the base by the external force; a first location limiting element which limits the movement of the shuttle with respect to the base so that the slider stops when the slider reaches the first location; and a second location limiting element which limits the movement of the shuttle with respect to the base so that the slider stops when the slider reaches the second location, wherein at least one of the first location limiting element and the second location limiting element is an elastic stopper comprising a groove formed on one side of the shuttle and the base adjacent to the shuttle, and an elastic element protruding on the other side.
