PROBLEM TO BE SOLVED: To feed nozzle chips in a fixed direction by successively controlling operation steps so as to regulate the direction of charged and stored nozzles chips, by automatically lining up a plurality of nozzle chips on a nozzle chip storage container, by mounting a plurality of nozzle chips from lined-up containers, and by making dispensation under dispensing instructions. SOLUTION: Nozzle chips dropped onto a buffer unit 9 from a hopper unit 1 are shifted onto a conveyer 3 by a suitable number, and are then fed onto a crawler unit 4 one by one. The unit 4 stores and transfers the nozzle chips one by one, and nozzle chips lined up horizontally, are dropped one by one onto a stocker unit 5, and are then lined up in an arbitrary number. The front ends of thus lined-up nozzle chips are aligned together being directed downward, and are dropped onto a chuck unit 6. The nozzle chips on the chuck units 6 are dropped and arranged in nozzle chip storage containers which are successively moved. When all chips are stored in the container 7, the container 7 is moved to a position where the chips are mounted by five at each time, and accordingly, sample liquid is sucked up by a required quantity instructed by a host computer. |
