IPC: G01N35/10
Filed: 1981-07-16
Abstract: PURPOSE:To precisely detect whether dripping is present or not, by detecting a drop by variation of luminous flux caused by a small amount of a drop falling from a dispensating nozzle crossing the luminous flux. CONSTITUTION:Two photodetectors 12 and 13 are arranged to photodetect each luminous flux 10 and 11 from luminous flux generators 4 and 5. A container 14 is so arranged that a drop 2 of a reagent after crossing those pieces of luminous flux 10 and 11 falls therein. When the drop 2 of the reagent falls in the container 14, it crosses those pieces of luminous flux 10 and 11, so the photodetectors 12 and 13 vary in the quantity of photodetection and output signals appear at output terminals 15 and 16 when the drop 2 cross the pieces of luminous flux 10 and 11. One of those signals is delayed and those signals are ANDed to obtain bit drop detection signal.
