INK CARTRIDGE CHIP, INK CARTRIDGE, AND INK CARTRIDGE ADAPTIVE FRAME

摘要

An ink cartridge chip comprises an interface unit (21), a control unit (22), and a storage unit (23). The interface unit (21) is used for receiving a light control command sent by an imaging device, the light control command comprising ink cartridge identification information. The storage unit (23) is used for storing its identification information and state flag, the state flag comprising an executable state and a non-executable state. The control unit (22) is connected to any one of light-emitting units (24) and is used for executing the light control command, a type of the light control command comprising a light lightening command or a light extinguishing command. The control unit (22) is used for: when the interface unit (21) receives a light control command, controlling, according to the light control command and the state flag in the storage unit (23), the light-emitting unit (24) to execute the light control command, and after the light-emitting unit (24) executes the light control command, re-determining a state flag according to an association relationship between the ink cartridge identification information and identification information of the control unit (22). The ink cartridge chip can detect a location of an ink cartridge in an imaging device.
