Publication number: 20150233955Abstract: In a conventional conveyor line, an empty specimen rack conveyor line is provided separately from a specimen rack conveyor line having a specimen mounted thereon. However, crossing of the conveyor lines leads to the decrease in processing speed. Also, when a specimen rack conveyor line and an empty specimen rack conveyor line are configured on two stages, a vertical movement mechanism or the like needs to be added in order to connect the upper-stage conveyor line and the lower-stage conveyor line, and there is a possibility that the system is complicated and the cost thereof is increased. In the present invention, by connecting an empty holder conveyor line and a main conveyor line disposed up and down on two stages via one conveyor line having a horizontal part and an inclined part, crossing of the conveyor lines can be eliminated and an inexpensive structure can be achieved.Type: ApplicationFiled: August 30, 2013Publication date: August 20, 2015Inventors: Tomoyuki Nemoto, Tatsuya Fukugaki, Naoto Tsujimura

Publication number: 20140037503Abstract: 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.Type: ApplicationFiled: January 26, 2012Publication date: February 6, 2014Applicant: Hitachi High-Technologies CorporationInventors: Yukinori Sakashita, Katsuaki Takahashi, Tomoyuki Nemoto
