PROBLEM TO BE SOLVED: To smoothly deliver a liquid sample or specimen into a well without allowing inclusion of bubbles. SOLUTION: An automatic dispensing apparatus comprises a dispensing head having a nozzle for sucking/delivering a liquid in a sample container having a plurality of the wells, a shaft driving means for transferring the dispensing head in X, Y and Z axis directions, pistons for sucking/delivering the liquid through the nozzle, piston driving means for driving the pistons and a control data storage section storing control data including speed change profile of the driving means calculated on the basis of data on delivery amounts and well shapes. The apparatus is further provided with a drive control means for raising a distal end of a tip mounted on the nozzle when the liquid is delivered into the well according to rise of a liquid level in the well in response to the amount of delivery and moving the same along an internal profile line of the well by reading the control data from the storage section and driving the respective driving means.
