CARTRIDGE AND PRINTING MATERIAL SUPPLY SYSTEM

摘要

A cartridge comprises an ink supply structure, a terminal bearing structure, and a first re-striction 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.
