Printing material container, and board mounted on printing material container

A combination of a printing material container and a portion of an ink jet printing apparatus, the combination comprising:

• a portion of an ink jet printing apparatus, the portion comprising:
• a plurality of apparatus-side contact forming members and a short detection circuit,
• 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 of the portion of the ink jet printing apparatus 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 the short detection circuit of the portion of the ink jet printing apparatus, the short detection contact portion and the short detection circuit are adapted and 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,
• the contact portion that is farthest to the right is the right contact portion,
• the contact portion that is second farthest to the right is the short detection contact portion, and
• the left contact portion, the right contact portion, and two or more of the plurality of memory contact portions are arranged in a row of contact portions that extends in a substantially left-right direction, to define a row direction.
