1. An automatic analyzing device comprising: a reagent cartridge that includes a storing unit configured to store therein a reagent, a flow path configured to dispense the reagent from the storing unit, and a dispensing mechanism configured to dispense the reagent into a reaction cuvette through the flow path; and
processing circuitry configured to control the dispensing mechanism so as to dispose of the reagent in the flow path,
wherein the reagent cartridge includes a supply unit configured to supply the reagent in the storing unit to the dispensing mechanism and a valve provided between the storing unit and the supply unit, and
the processing circuitry is configured to
control the dispensing mechanism to change a shape of a lateral wall of the supply unit in a direction such that a volume of the supply unit is configured to increase and configured to let the reagent in the storing unit flow into the supply unit, and
control the dispensing mechanism to change the shape of the lateral wall of the supply unit in a direction such that the volume of the supply unit is configured to decrease and configured to let the reagent in the supply unit be dispensed from a dispense unit and be supplied to the reaction cuvette.
