1. An automatic analysis device comprising:
a specimen dispensing unit for dispensing a specimen;
an analysis unit for analyzing components included in the specimen;
a consumables holding unit for holding a consumable used for the analysis of the specimen;
a consumables remaining amount prediction unit for predicting the remaining amount or the remaining number of consumables held in the consumables holding unit; and
a device state control unit for controlling the state of the automatic analysis device, wherein
the state of the automatic analysis device includes a replenishment prohibition state in which replenishment of the consumables is prohibited, and a replenishment permission state in which replenishment of the consumables is permitted,
in the replenishment prohibition state, the specimen dispensing unit performs dispensing, and the analysis unit performs analysis,
in the replenishment permission state, the specimen dispensing unit does not perform dispensing, and the analysis unit performs analysis, and
in response to determining that the remaining amount or the remaining number of consumables predicted by the consumables remaining amount prediction unit is equal to or less than a predetermined value, the device state control unit causes the automatic analysis device to transition to the replenishment permission state.
