Recording material delivery system for recording material-consuming apparatus; circuit board; structural body; and ink cartridge

A circuit board electrically connectable to a recording material-consuming apparatus, the recording material-consuming apparatus having a recording material delivery member adapted for receiving recording material and a plurality of electrical contact members, the circuit board comprising:

• a board;
• and
• a plurality of first terminals and two second terminals arranged on the board, the plurality of first terminals and the two second terminals, each including a contact portion that, when the circuit board 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 contact portions of the plurality of terminals being arranged in a plurality of lines,
• the plurality of first terminals being adapted for communicating with a memory device, the plurality of first terminals including a power supply terminal adapted for receiving a power supply potential that is different from a ground potential of the recording material-consuming apparatus,
• the two second terminals being adapted for detecting whether the circuit board is installed in the recording material-consuming apparatus,
• 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 an installation direction, with the first line leading the second line in the installation direction,
• the contact portions of the two second terminals being situated in the first line with the contact portion of the power terminal situated between the contact portions of the two second terminals in the first line.

A structural body installable in a recording material-consuming apparatus having a recording material delivery member adapted to receive recording material and a plurality of electrical contact members, the structural body comprising:

• a main unit;
• and
• a board positioned on the main unit, the board comprising:
• a plurality of first terminals;
• and
• two second terminals,
• the plurality of first terminals and two second terminals each including a contact portion that, when the structural body 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 main unit defining an installation direction, the installation direction corresponding to the direction with which the contact portions of the plurality of first terminals and the two second terminals move respect to the electrical contact members, the contact portions being arranged in a plurality of lines,
• the plurality of first terminals being adapted to be electrically coupled to a memory device, the plurality of first terminals including a power supply terminal adapted for receiving a power supply potential that is different from a ground potential of the recording material-consuming apparatus,
• the two second terminals being adapted for detecting whether the structural body is installed in the recording material-consuming apparatus,
• 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, and
• the contact portions of the two second terminals being situated in the first line with the contact portion of the power terminal situated between the contact portions of the two second terminals in the first line.

An ink cartridge installable in a printer having a plurality of electrical contact members, the ink cartridge comprising:

• an ink receptacle portion for containing ink, the ink receptacle portion having an ink delivery port with an exit adapted to deliver ink from the ink receptacle portion to the printer;
• a memory device;
• and
• a plurality of first terminals and two second terminals each including a contact portion that, when the ink cartridge is installed in the printer, contacts a corresponding one of the electrical contact members of the printer, the contact portions of the plurality of first terminals and the contact portions of two second terminals being arranged in a plurality of lines,
• the ink cartridge adapted to define an installation direction, the installation direction corresponding to the direction the terminals move with respect to the electrical contact members,
• the plurality of first terminals being electrically coupled to the memory device, the plurality of first terminals including a power supply terminal adapted for receiving a power supply potential that is different from a ground potential of the printer,
• the two second terminals being adapted for detecting whether the ink cartridge is installed in the printer,
• 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, and
• the contact portions of the two second terminals being situated in the first line with the contact portion of the power terminal situated between the contact portions of the two second terminals in the first line.
