US 4,872,091 A · Memory cartridge

Abstract

A memory cartridge for use with a printer, a copier, a word processor and other electronic equipment as an external memory. A connector corresponding to that of the equipment is provided on one end of a casing which accommodates a printed circuit board, which is loaded with memory devices. A plurality of memory cartridges may be connected to a buffer of the equipment via the individual connectors. A grounding plate for making contact with a grounding portion of the printed circuit board is disposed on the memory cartridge close to the connector. This reliably connects the memory cartridge to ground. Further, since which one of the memory cartridges is selected can be determined, it is not necessary for the equipment to be provided with buffers and related circuits in one-to-one correspondence to the memory cartridges.
