The present invention performs cleaning on the inner and outer surfaces of a dispensing nozzle without reducing the processing speed of a device. To achieve the object, a feature of the invention is that a dispensing nozzle rinse tank includes a rinse liquid supply port. More specifically, by suctioning rinse liquid from the rinse liquid supply port provided on the dispensing nozzle rinse tank and discharging the rinse liquid into the rinse tank, the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time. According to the invention, it is only required that a rinse liquid supply port be provided on the dispensing nozzle rinse tank, the structure is simple. Moreover, because the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time by shortening the movement distance of the dispensing nozzle, analyses can be performed without reducing the processing speed of the device. |
