Printing material container, and board mounted on printing material container
CAFCFirst Claim
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,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, andthe 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.

Abstract
A printing material container detachably attachable to a printing apparatus having apparatus-side terminals. The container can comprise an electrical device, a memory device and a plurality of terminals. First and second terminals can be coupled to the electrical device and a plurality of memory terminals can be coupled to the memory device. Terminal contact portions are present where the terminals contact a respective apparatus side contact forming member. A short detection contact portion can be positioned to contact a contact forming member that itself is coupled to a short detection circuit of the printing apparatus. The terminals can be arranged with the memory terminal contact portions located to the left of the second terminal contact portion and to the right of the first terminal contact portion. The contact portion that is second farthest to the right can be the third contact portion.
