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.

Claims

1. A printing material container detachably attachable to a printing apparatus, the printing apparatus having a plurality of apparatus-side terminals, the printing material container comprising:

a housing;

a flared section at the upper edge of the front face of the housing;

an ink supply opening having an exit portion on an exterior portion of the printing material container, the ink supply opening adapted to supply ink from the printing material container to the printing apparatus;

a first device;

a second device; and

a terminal group that includes a plurality of first terminals, at least one second terminal and at least one third terminal, wherein;

the first terminals are electrically connected to the first device and respectively include a first contact portion for contacting a corresponding terminal among the apparatus-side terminals, the at least one second terminal is electrically connected to the second device and includes a second contact portion for contacting a corresponding terminal among the apparatus-side terminals, the at least one third terminal is for the detection of electrical shorting between the at least one second terminal and the at least one third terminal and includes a third contact portion for contacting a corresponding terminal among the apparatus-side terminals, the at least one second contact portion, the first contact portions, and the at least one third contact portion are arranged to form multiple rows.
