Chip for ink-jet printer and ink-jet printer

Abstract

The present invention provides a chip for an ink-jet printer and an ink-jet printer. The chip for an ink-jet printer comprises a hollow portion, a memory, two installation and detection terminals and a power terminal connected with the memory. Each installation and detection terminal is provided with an installation and detection contact portion being in electrical contact with a printer contact probe, the power terminal is provided with a power contact portion being electrical contact with the printer contact probe, the power terminal is arranged at the end surface of the hollow portion, the two installation and detection contact portions are arranged at two sides of the hollow portion and installed at the installation direction of a printer along the chip, and the distances between the two installation and detection contact portions and the front end of the chip are smaller than the distance between the power contact portion and the front end of the chip. The chip for ink-jet printer and the ink-jet printer overcome the defects in the prior art and effectively ensure the stable reliability of the usage of the chip.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a chip for an inkjet printer and the inkjet printer. Background technique [0002] There are many chips and ink cartridges for inkjet printers. Chips for inkjet printers are used to store information such as manufacturer information, ink volume information, ink cartridge category information, ink color, etc. Chips for inkjet printers play an important role in the normal operation of inkjet printers. decisive role. [0003] Among them, Chinese Patent No. 201110375124.4 discloses a circuit substrate, refer to the attached figure 1 It can be seen that the circuit substrate includes a substrate (chip) 200, and substrate terminals 210-290 are arranged on the substrate 200, and the substrate terminals 210-290 are arranged in two rows, and each terminal has its own contact portion cp, and the contact portion cp is a connection point. The location where a mechanism (stylus) (no...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a chip for an inkjet printer and an inkjet printer, which can effectively overcome the problem in the prior art that the power terminal on the chip has been connected to the corresponding contact pin on the printer, but the installation detection terminal cannot be established. The normal connection causes the printer to fail to recognize the chip or the chip and the printer are damaged, and it can also solve the technical problem of contact pin wear
