Storage device and consumption container
A storage device includes an interface unit, a storage unit, a detection unit and a control unit. When the detection unit detects a preset trigger condition and the total surplus of the recording material is greater than the capacity of the recording material, the control unit effects the updating of the total surplus of the recording material stored in the storage unit and the erasing of the surplus of the erasable recording material or the consumption amount of the erasable recording material as a calculation value. When the total surplus of the recording material is less than or equal to the capacity of the recording material, the control unit will not actively update the total surplus of the recording material or the consumption amount of the recording material in the storage unit. Provided is a consumption container, which can better manage the data in the storage device.
