MATRIX PRINTER COMBINATION SYSTEM

摘要

A replaceable font module for a printer includes an interrogable storage containing information representing graphic patterns and is connected to cooperate with a printer upon insertion within a corresponding receptacle. The module and receptacle are configured to allow insertion without intense operator attention by virtue of a camming surface on the module that cooperates with a hook-like latch of the receptacle to provide an undulating but positive latching motion in response to a simple operator insertion motion. As a part of the latching motion, a wiping action to assure a high quality contact with conductor pads on the module that provide a transfer point for the communication path to the storage.
