Cartridge and printing material supply system

摘要

A cartridge comprises an ink supply structure, a terminal bearing structure, and a first restriction portion. The terminal bearing structure has terminals arranged in a terminal plane which is neither parallel nor perpendicular to a plane defined by a mounting direction leading edge of the ink supply structure, so that the contact portions of the terminals receive a force in a direction opposite (RD) from the mounting direction. An engagement portion of the first restriction portion is provided at a position adjacent to the terminal bearing structure.

主权项

1. A liquid supply system configured to supply liquid to a printing apparatus, the printing apparatus comprising a lever having an engagement portion and a plurality of apparatus-side contact forming members, the liquid supply system comprising:
an electrical device configured to be electrically connecting to the plurality of apparatus-side contact forming members; a liquid source; a liquid supply structure adapted and configured to supply liquid from the liquid source to the printing apparatus, the liquid supply structure having a mounting direction leading edge defining a plane; and an adapter having:
electrically conductive terminals coupled to the electrical device, the terminals arranged to make contact with and receive elastic force from the contact forming members at contact portions of the terminals when the supply system supplies liquid to the printing apparatus, the contact portions of the terminals arranged substantially in a contact portion plane which is neither parallel nor perpendicular to the plane defined by the leading edge; anda first restriction portion provided on a front of the adapter including an engagement portion configured to engage with the engagement portion of the lever so as to restrict movement of the adapter in a direction opposite the mounting direction, the first restriction portion positioned adjacent at least one of the contact portions.
