PROBLEM TO BE SOLVED: To expand the working range of the motor-operated pipette section of a dispensing device or the front end section of the pipette section which sucks and discharges a liquid. SOLUTION: The motor-operated pipette section which can suck and discharge the liquid can be exchanged automatically in accordance with dispending amounts. The liquid dispending device can arbitrarily expand its working area for sucking and discharging liquids by using a plurality of units, each of which is constituted by attaching a basic driving system to a rotatable driving mechanism and the rotatable driving mechanism to a driving mechanism that can move in the unmovable direction of the rotatable driving mechanism. In the basic driving system, the pipette section or the front end section of the pipette section which sucks and discharges the liquid is attached to a linearly driving mechanism that can move in one, two, or three of forward, backward, leftward, and rightward directions. |
