  • Publication number: 20240125812
    Abstract: An automatic analyzer includes a dispensing mechanism having at least one horizontal drive shaft and one vertical drive shaft for moving the dispensing nozzle, a first mechanism having a stop position at which the dispensing nozzle is stopped, and a control section for positioning the dispensing nozzle with the stop position of the first mechanism. A member is disposed on the first mechanism to indicate predetermined first and second positions of the first mechanism so that the first and the second positions are detected by sensing the member using the dispensing nozzle. Based on the displacement between the first and the second positions indicating the displacement of the relative position between the dispensing mechanism and the first mechanism, the control section calculates a correction value for correcting the displacement of the stop position caused by fluctuation in a relative position between the dispensing mechanism and the first mechanism.
