To clean a nozzle that is part of an automated analyzer and is provided with both a tubular discharge unit that discharges a cleaning liquid and a tubular suction unit that suctions in cleaning liquid that was discharged from the discharge unit and is running down an outer surface, first the discharge unit is made to start discharging, and then in parallel with said discharging, the suction unit is made to start suctioning. After the suction unit has suctioned in the cleaning liquid running down the aforementioned outer surface for a prescribed length of time, the suctioning is temporarily stopped. Next, after a prescribed amount of the cleaning liquid has accumulated in a cleaning tank, the discharging is stopped, and with the suction unit immersed in the cleaning liquid accumulated in the cleaning tank, the suctioning is restarted.

Automated analyzer and nozzle-cleaning method

A container supply unit and an automated analyzer in which anomalous orientations of containers ejected from a container (cuvette) ejection part can be prevented. This container supply unit has a container storage part, a container ejection part, and a container alignment part. The container ejection part includes a circular belt, placement members provided on said circular belt, and a belt rotation mechanism. The belt rotation mechanism rotates the circular belt in an R direction, forming an outward leg along which the placement members move upwards and a return leg along which the placement members move downwards. The placement members carry containers placed thereon on the outward leg and eject said containers to the container alignment part between the outward leg and the return leg. The top of each placement member during the outward leg comprises the following: a first inclined surface that is sloped upwards from one end, on the circular-belt side, towards the other end; and a second inclined surface that is sloped downwards from one end, which connects to the first inclined surface, towards the other end.
