  • Publication number: 20240302396
    Abstract: An automatic analyzer can be miniaturized as a whole and can accurately determine presence or absence of a sample container and a type thereof. The automatic analyzer of includes a conveyance line for conveying a loaded sample container; an identification information reading device that reads identification information attached to the sample container; and a container height detection device. The identification information reading device and the container height detection device perform reading and detection when the sample container is at a common position on the conveyance line. The container height detection device includes sensors having different height ranges for a detection target, a part of the sensors being disposed on the same side as the identification information reading device with respect to the conveyance line, and the rest of the sensors being disposed on the opposite side of the identification information reading device with respect to the conveyance line.

  • Publication number: 20230408535
    Abstract: An automatic analyzer includes: an analysis unit performing analysis of a sample; a thin waste fluid tank housing a waste fluid produced by a process of analyzing the sample; an attention attraction thin waste fluid height sensor detecting that the waste fluid has reached a predetermined reference amount, the waste fluid being housed in the thin waste fluid tank; a timer unit starting counting time when the attention attraction thin waste fluid height sensor detects that the waste fluid has reached the reference amount; and a control unit controlling operation of the analysis unit. The control unit determines, when an operator instructs starting analysis, whether to permit starting analysis by the analysis unit based on whether a count result obtained by the timer unit reaches predetermined reference time. Accordingly, it is possible to operate the analyzer while workflows are easily considered and unexpected measurement stops are avoided.
