The first conveyance path conveys a first container rack that holds a container housing the sample. The second conveyance path conveys a second container rack that holds a container housing at least one of a detergent solution for cleaning a probe that dispenses the sample, a diluent for diluting the sample, a buffer solution for mixing the sample, a solution used for a blank test with the sample, and a solution for performing calibration measurement for the apparatus. The sample dispensing mechanism is configured so that the probe can aspirate a liquid in the container of the first container rack and the second container rack. The processing circuitry controls operations of the first conveyance path, the second conveyance path, and the sample dispensing mechanism. ## Claims ### Claim 1 An automatic analyzing apparatus configured to measure a mixed liquid of a reagent and a measurement target sample to analyze components contained in the sample, the automatic analyzing apparatus comprising: a first conveyance path configured to convey a first container rack that holds a container housing the sample; a second conveyance path configured to convey a second container rack that holds a container housing at least one of a detergent solution for cleaning a probe for dispensing the sample, a diluent for diluting the sample, a buffer solution for mixing the sample, a solution used for a blank test with the sample, and a solution for performing calibration measurement for the automatic analyzing apparatus; a sample dispensing mechanism that comprises the probe and configured so that the probe is able to aspirate a liquid housed in the container of the first container rack and a liquid housed in the container of the second container rack; and processing circuitry configured to control operations of the first conveyance path, the second conveyance path, and the sample dispensing mechanism. ### Claim 2 (depends on 1) The automatic analyzing apparatus according to claim 1, wherein the second container rack on the second conveyance path is conveyed from a front side to a rear side of the automatic analyzing apparatus by the second conveyance path so that the liquid housed in the container of the second container rack is able to be used in common for the sample housed in the container of the first container rack on the first conveyance path. ### Claim 3 (depends on 1) The automatic analyzing apparatus according to claim 1, further comprising: a coagulation reaction cuvette holding part configured to hold a plurality of reaction cuvettes for coagulation measurement; and a colorimetric reaction cuvette holding part configured to hold a plurality of reaction cuvettes for colorimetric measurement, wherein the sample dispensing mechanism is configured to be able to dispense the liquid aspirated by the probe to the coagulation reaction cuvette holding part and the colorimetric reaction cuvette holding part. ### Claim 4 (depends on 1) The automatic analyzing apparatus according to claim 1, wherein the first conveyance path and the second conveyance path are disposed side by side, and respectively convey the first container rack and the second container rack at least from a front side to a rear side of the automatic analyzing apparatus. ### Claim 5 (depends on 1) The automatic analyzing apparatus according to claim 1, wherein the first conveyance path comprises: an outgoing conveyance path configured to convey the first container rack from a front side to a rear side of the automatic analyzing apparatus; a returning conveyance path configured to convey the first container rack from the rear side to the front side of the automatic analyzing apparatus; and a relay conveyance path configured to convey the first container rack from the outgoing conveyance path to the returning conveyance path. ### Claim 6 (depends on 1) The automatic analyzing apparatus according to claim 1, further comprising: a cleaning unit configured to clean the probe, wherein the processing circuitry controls the sample dispensing mechanism to perform a cleaning operation for the probe by aspirating the detergent solution held by the container of the second container rack by the probe and discharging the detergent solution by the cleaning unit. ### Claim 7 (depends on 1) The automatic analyzing apparatus according to claim 1, wherein the processing circuitry controls the sample dispensing mechanism to perform at least one of: an operation of dispensing the diluent held by the container of the second container rack to a reaction cuvette with the probe; an operation of dispensing the buffer solution held by the container of the second container rack to the reaction cuvette with the probe; and an operation of dispensing a solution for performing calibration measurement for the automatic analyzing apparatus, the solution being held by the container of the second container rack, to the reaction cuvette with the probe.
