Patent ID: 8540347

Claim:
A recording material delivery system installable in a recording material-consuming apparatus having a plurality of electrical contact members, the recording material delivery system comprising: a recording material receptacle portion for containing a recording material, the recording material receptacle portion having a recording material delivery port with an exit adapted to deliver recording material from the receptacle portion to the recording material consuming apparatus; a memory device; and a plurality of first terminals and two second terminals each having a contact portion that, when the recording material delivery system is installed in the recording material-consuming apparatus, is configured to be contacted with a corresponding one of the electrical contact members of the recording material-consuming apparatus, the recording material delivery system adapted to define an installation direction, the installation direction corresponding to the direction the terminals move with respect to the electrical contact members, the contact portions of the plurality of first terminals being arranged in at least a first line and a second line, the first and second lines substantially orthogonal to the installation direction, with the first line leading the second line in the installation direction, the plurality of first terminals electrically coupled to the memory device, the plurality of first terminals including a power supply terminal adapted for receiving a power supply potential that differs from a ground potential of the recording material-consuming apparatus, and the two second terminals adapted to be used for detecting whether the recording material delivery system is installed in the recording material-consuming apparatus, the contact portions of the two second terminals being situated in the first line and the contact portion of the power supply terminal situated between the contact portions of the two second terminals in the first line.
