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: 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. The automatic analysis apparatus is characterized by being provided with a control unit that performs first liquid supply processing when the power-cutting instruction from the power-cutting instructing unit is not received, and that performs second liquid supplying processing when the power-cutting instruction from the power-cutting instructing unit is received, thus supplying the liquid to the flow cell.

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.
