Embodiment 1

[0038] Such as figure 1 As shown, it is a schematic structural diagram of the ink cartridge provided in the embodiment of the present application. Ink cartridge 1 comprises ink cartridge main body 11 and ink supply part 12, and ink cartridge main body 11 is configured to store the ink that prints, and ink supply part 12 is generally formed on the bottom wall of ink cartridge main body 11, and when ink cartridge 1 is packed into inkjet printer, it is connected with inkjet printer. The ink supply pipe of the inkjet printer is connected to deliver the ink in the ink cartridge body 11 to the print head of the inkjet printer. The ink cartridge 1 is detachably installed in the inkjet printer for printing. The ink cartridge 1 is equipped with a chip 2 . For example, the chip 2 can be installed on an outer wall of the main body of the ink cartridge 1 . The chip 2 has a plurality of exposed connection terminals, which are configured to be in electrical contact with the contact pins of t...

Embodiment 2

[0055] This embodiment mainly describes the working principle of the read controller 24 on the basis of the first embodiment. The read controller 24 is respectively connected to the communication module 21 and the storage module 22 , and the read controller 24 executes a read operation, and is responsible for reading the rewritable data stored in the storage module 22 and sending it to the communication module 21 . The read controller 24 is configured to read out the rewritable data in the storage units satisfying the read conditions among the multiple storage units in the rewritable data storage area 300 , and send the rewritable data to the communication module 21 .

[0056] In one embodiment, the readout condition may be a specific condition of a readout sequence. Wherein, the mode for realizing the read order can be: the read controller 23 is provided with a register and a storage unit identification bit, for example, “0” can be used to indicate that the data of the first ...

Embodiment 3

[0064] Such as Figure 7 As shown in , it is a schematic diagram of the memory structure of the memory module of the chip provided in Embodiment 3 of the present application. In this embodiment, the storage module 22 includes a rewritable data storage area 300 for storing ink quantity data, and the rewritable data storage area 300 includes more than two storage units. for your convenience, Figure 7 Only three storage units are shown in : a first storage unit 310 , a second storage unit 320 and a third storage unit 330 . In addition, the storage module 22 also includes other data storage area 400 configured to store read-only data such as the production date of the ink cartridge. Same as Embodiment 1, each storage unit in the rewritable data storage area 300 is used to store ink volume data, and each storage unit can complete the storage of ink volume data individually and completely, and the write controller 23 A value comparison circuit and a judgment circuit (that is, a ...

Abstract

The invention relates to the technical field of printing imaging, in particular to a chip and an imaging box. The chip can be arranged on the imaging box and comprises a communication module, a storage module and a writing controller, the communication module is arranged to conduct data receiving and transmitting with a printer, the storage module is provided with at least one rewritable data storage area, each rewritable data storage area comprises at least two storage units, each storage unit is used for storing readable data, the writing controller is connected with the communication moduleand the storage module, compares the data sizes of the rewritable data stored in at least two storage units in the rewritable data storage area and selects the storage unit meeting the writing-in condition according to a comparison result, and the selected storage unit is used for writing in the rewritable data transmitted by the communication module. In this way, the problem that in the prior art, when the number of times of continuously writing in wrong data is larger than the number of the storage areas, the normal historical ink quantity data in the storage units can be covered and cannotbe recovered is solved.

Description

technical field [0001] The present application relates to the technical field of printing and imaging, in particular to a chip and an imaging box. Background technique [0002] Recording devices, such as printers, copiers, and facsimile machines, are configured to record information to be recorded on recording media such as paper through recording materials such as ink. A recording device generally includes a recording device main body and an ink cartridge. The ink cartridge is generally detachably mounted on the recording device, and is equipped with a chip configured to mark ink amount data information such as the consumption or remaining amount of ink in the ink cartridge. The chip is usually mounted on the ink cartridge in a detachable manner, and a storage element is arranged in the chip to store rewritable data such as ink consumption or remaining amount, and other read-only data related to the ink cartridge. When the ink cartridge is installed on the recording devic...
