LE9-80-036 FONT MODULE FOR MATRIX PRINTER Abstract or the Disclosure A replaceable font module for a printer includes an interrogable storage containing information repre- senting 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. For the presently preferred implementation, the contacts of both the module and the receptacle are recessed so as to be protected from injury and inadvertent static discharges that might cause component damage. Also the operator, who may be unfamiliar with electronic components, is isolated from electrical contacts and handles a sturdy housing which is easily stored.
