Abstract:
1. A printing material container 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 printing material container comprising: a body; an ink supply opening having an exit on an exterior portion of the body, adapted to supply ink from the printing material container to the printing apparatus; a memory device adapted to be driven by a memory driving voltage; and a plurality of terminals having contact portions arranged to contact corresponding apparatus-side contact forming members so that electrical communication is enabled with the ink jet printing apparatus, the contact portions including a plurality of memory contact portions electrically coupled to the memory device, a left contact portion arranged to have applied thereto a voltage higher than the memory driving voltage, a right contact portion arranged to have applied thereto a voltage higher than the memory driving voltage, and a short detection contact portion arranged to electrically contact a contact forming member that itself is electrically coupled to a short detection circuit of the printing apparatus, the short detection contact portion is arranged for detecting a short between the short detection contact portion and at least the right contact portion, wherein: the contact portions are arranged so that, when the terminal arrangement is viewed from the vantage of the contact forming members, with the terminals oriented as if in contact with the contact forming members so that electrical communication is enabled with the ink jet printing apparatus, and with the printing material container oriented with the exit of the ink supply opening facing downwards: the contact portion that is farthest to the left is the left contact portion,
