Abstract:
1. An ink cartridge for mounting on an ink jet printing apparatus, the ink jet printing apparatus having a print head and a plurality of apparatus-side contact forming members, the ink cartridge comprising: a body having a length, a width, and a height; an ink supply opening having an exit on an exterior portion of the body, adapted to supply ink from the cartridge to the printing apparatus; a memory device adapted to be driven by a memory driving voltage; an electronic device adapted to receive a voltage higher than the memory driving voltage; and a plurality of terminals adapted and positioned to contact corresponding apparatus-side contact forming members so that electrical communication is enabled with the ink jet printing apparatus, the terminals including a plurality of memory terminals electrically coupled to the memory device, a first high voltage terminal coupled to the electronic device, and a second high voltage terminal coupled to the electronic device, wherein: the terminals are arranged so that, when the terminal arrangement is viewed with the ink cartridge oriented with the exit of the ink supply opening at the bottom, the terminal farthest to the left is the first high voltage terminal and the terminal that is the farthest to the right is the second high voltage terminal, all of the memory terminals are to the right of the first high voltage terminal and to the left of the second high voltage terminal, and the second high voltage terminal is separated from the nearest memory terminal by a greater distance than the distance that separates any two of the memory terminals that are adjacent to each other.
