Zusammenfassung: | The utility model provides an ink box, and relates to the technical field of ink-jet printers. The ink box comprises a shell and a chip. The housing has an upper surface on which a light shielding portion is provided for insertion between a light generator and a light receiver of an optical sensor of a cartridge mounting portion of an ink jet printer; the chip is arranged on the upper surface, the chip is located on the rear side of the light shielding part, the chip is provided with three electrical interfaces, and the electrical interfaces are used for being connected with contact pins of the box mounting part; and the three electrical interfaces are sequentially arranged at intervals in the width direction of the shell. The at least two adjacent electrical interfaces are not aligned in the length direction of the shell, so that the corresponding lengths of the adjacent electrical interfaces on the chip in the length direction of the shell can be reduced, and the possibility of short circuit between the adj |
