Abstract

A printing material container is detachably attachable to a printing apparatus having a plurality of apparatus-side terminals. The printing material container comprises 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. The plurality of first terminals are connected to the first device and respectively include a first contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one second terminal is connected to the second device and includes a second contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one third terminal is for the detection of 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 plurality of apparatus-side terminals. The at least one second contact portion, the plurality of the first contact portions, and the at least one third contact portion are arranged so as to form one or multiple rows. The at least one second contact portion is arranged at an end of one row among the one or multiple rows.

Claims

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

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 plurality of first terminals are electrically connected to the first device,

the at least one second terminal is electrically connected to the second device,

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,

each of the terminals has a circumferential edge, a portion of the circumferential edge of the third terminal faces a portion of the circumferential edge of the second terminal and a portion of the circumferential edge of one said first terminal faces another portion of the circumferential edge of the second terminal,

the length of the portion of circumferential edge of the third terminal is greater than that of the portion of the circumferential edge of the one said first terminal.
