Abstract:
1. A storage device applied in a printer, comprising: an interface unit adapted to establish a communication connection between the storage device and the printer, wherein the interface unit comprises a plurality of connecting terminals or an antenna; a storage unit, adapted to store a total remaining amount of a recording material and a capacity of the recording material, an initial remaining amount of the recording material and/or an initial consumption of the recording material, and a rewritable remaining amount of the recording material and/or a rewritable consumption of the recording material; a detection unit, adapted to detect a signal of the interface unit; and a control unit, adapted to control updating the total remaining amount of the recording material stored in the storage unit, rewrite the rewritable remaining amount of the recording material into a calculated value of the rewritable remaining amount of the recording material or rewrite the rewritable consumption of the recording material into a calculated value of the rewritable consumption of the recording material, in the case that the detection unit detects a predetermined trigger condition and the total remaining amount of the recording material is more than the capacity of the recording material; and adapted to non-spontaneously update the remaining amount of the recording material or the consumption of the recording material stored in the storage unit in the case that the total remaining amount of the recording material is less than or equal to the capacity of the recording material, wherein the interface unit, the storage unit, the detection unit, and the control unit are formed on a printed circuit board.
