Abstract: An object of the invention is to provide an automatic analyzer in which an adjustment accuracy of a cleaning liquid amount is improved by detecting a change in a cleaning water amount with high sensitivity. The automatic analyzer according to the invention includes a dispensing mechanism including a dispensing probe configured to dispense a sample or a reagent into a reaction container, a cleaning nozzle configured to discharge a cleaning liquid to the dispensing probe, and a control unit configured to control the dispensing mechanism. A height of the cleaning liquid discharged from the cleaning nozzle is detected at plural positions at which horizontal distances from the cleaning nozzle are different, so as to determine a discharging state of the cleaning liquid, and at least one of the plural positions is farther from the cleaning nozzle than a cleaning position of the dispensing probe.

The automatic analyzer includes a plurality of reagent dispensing mechanisms that dispense a reagent from a reagent bottle into a reaction container. A plurality of reagent disks store the reagent bottles. The reagent carrying-in positions are provided in the respective reagent disks to put in the reagent bottles to the respective reagent disks. A carrying mechanism that carries the reagent bottles between the respective reagent carrying-in positions and a reagent bottle gripping position, in which when an automatic analyzer is viewed from a vertically upper side, the reagent bottle gripping position being positioned between the reagent carrying-in positions on a device front side of the automatic analyzer.

Abstract: To continuously monitor a tilt amount of an automatic analyzer without affecting an analysis operation. An automatic analyzer includes a plural number of adjuster feet 37 arranged on a frame bottom surface 72a and supporting a frame 70, a mechanism base 35 supported by a frame upper surface 72b, a tilt sensor 60 arranged on the mechanism base, and an analysis unit 45 determining whether a tilt amount of the mechanism base based on sensing data from the tilt sensor exceeds an allowable amount, in which the tilt sensor is arranged at a position not overlapping with the adjuster foot in top view.

Abstract: To provide an automatic analyzer and a sample aspiration method in an automatic analyzer capable of analyzing a sample of further minute amount compared than before. In aspirating the sample, a sample dispensing mechanism 13, 14 is controlled so as to detect the liquid level L1, to thereafter allow a dispensing probe 13a, 14a of the sample dispensing mechanism 13, 14 to be dropped and stopped below the liquid level L1, to thereafter allow the dispensing probe 13a, 14a of the sample dispensing mechanism 13, 14 to be elevated and stopped, and to thereafter allow the dispensing probe 13a, 14a of the sample dispensing mechanism 13, 14 to be further dropped while aspirating the sample.

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.

Abstract: The purpose of the present invention is to constantly keep a state in a flow cell steady by filling a detection flow channel with a liquid. The configuration of the present invention for solving the aforementioned problem is as follows. Specifically, the present invention is an automatic analysis apparatus provided with a detection unit including a flow cell that accommodates a liquid serving as an analysis subject; a suction nozzle that is positioned upstream of the flow cell and that sucks the liquid to be introduced into the flow cell; a pump that is positioned downstream of the flow cell and that supplies the liquid to the flow cell; flow channels that connect the flow cell, the suction nozzle, and the pump; a power source; and a power-cutting instructing unit that gives an instruction to cut the power supply at least to the pump.

Abstract: In the case of adopting a configuration in which reagent bottles are radially disposed on a reagent disk and a reagent dispensing mechanism is rotated to access the reagent bottles, one reagent bottle includes a plurality of suction ports in which suction positions are different from each other, resulting in prolonging a step of dispensing a reagent. The invention is directed to an automatic analyzer including: a reagent disk that accommodates a plurality of reagent bottles including a plurality of suction ports and conveys the reagent bottles to a desired position by rotating in a circumferential direction around a central axis; and a reagent dispensing mechanism that rotates around a rotational axis and sucks a reagent of the reagent bottle placed at a predetermined position on the reagent disk. The reagent bottle is accommodated in the reagent disk such that the central axis of the reagent bottle and a diameter of the reagent disk form a predetermined inclination.

Abstract: An automatic analyzer includes a flow cell detector, a nozzle that is connected to the flow cell detector by a flow path and aspirates or discharges liquid, a reservoir that is provided with a table and a table driving mechanism that rotates or moves the table up and down, and a cleaning tank that is disposed on the table. A position of the nozzle is fixed, and a cleaning water discharge port discharges cleaning water used for cleaning the nozzle at an angle ? with respect to a plane perpendicular to a central axis of the nozzle. An upper part of a side wall of the cleaning tank is continuous with an upper discharge unit at a side facing a discharge outlet provided in the reservoir and a spatula-shaped part projects outward of the cleaning tank at a side facing the upper discharge unit.

Abstract: An automated analyzer includes a container installation portion in which a container, such as a reagent container, has a protrusion and an openable and closable lid. A lid opening and closing mechanism opens and closes the lid and includes an arm portion having an arm and a horizontal driving portion which moves the arm in a first horizontal direction. The arm includes a protrusion contacting portion that includes a first surface having an angle greater than 0 degrees and less than 90 degrees when the horizontal surface is set as 0 degrees. The lid opening and closing mechanism portion opens the lid by moving the arm in the first horizontal direction, contacting the lid protrusion on the first surface of the protrusion contacting portion, and then moving the lid protrusion along a shape of the first surface in a vertical direction, until the lid is opened.
