1. An automatic analyzer comprising:
a detector unit to analyze a reaction solution of a sample and a reagent; a plurality of dispensing nozzles supported by a common arm where the nozzles are moved to dispense the sample or the reagent; and a rinse tank for rinsing the dispensing nozzles, the rinse tank having a top and a bottom spaced from each other in a first direction, wherein the rinse tank includes: a plurality of first rinse liquid discharge ports arranged along the bottom of the rinse tank, each first rinse liquid discharge port being constructed to supply a first rinse liquid and facing the top of the rinse tank; a plurality of second rinse liquid discharge ports arranged along the top of the rinse tank, each second rinse liquid discharge port being constructed to supply a second rinse liquid to flow to an exterior of one of the dispensing nozzles when aligned therewith, wherein the first rinse liquid discharge ports are offset with respect to the second rinse liquid discharge ports in both the first direction and a second direction perpendicular to the first direction; and a rinse liquid supply pipe connecting the first, rinse liquid discharge ports and a first rinse liquid supply, the rinse liquid supply pipe supplying the first rinse liquid for rinsing an inner wall of one of the dispensing nozzles from below, wherein each dispensing nozzle is rinsed by moving from a first position aligned with one of the first rinse liquid discharge ports to a second position aligned with one of the second rinse liquid discharge ports, and wherein the dispensing nozzles displace only in the second direction when moving from the corresponding first position to the corresponding second position. |
