FIELD: printing.SUBSTANCE: group of inventions relates to a system of supplying the recording material for the device for consumption of the recording material, to the printed circuit board, to the structure and the ink cartridge. On the printed circuit board of the ink cartridge, a plurality of outputs is provided, and a plurality of lines is formed by the contact parts of the plurality of outputs. In the first line among the plurality of lines the contact parts of two parts for detecting attachment are arranged, and a contact part of the power output is located between them. The first line may be located on the leading side when the ink cartridge is moved in the predetermined direction and mounted on the printing device, or the first line may be the line closest to the opening of the ink supply port, or the first line may be the line closest to the ink supply needle.EFFECT: proposed group of inventions increases the quality of electrical contact.48 cl, 36 dwg |
