Abstract

A multi-purpose terminal device is adapted for connection to a data processing system, an automatic text processing unit and/or a communication network. An input and control keyboard is provided for controlling connections and for adding information to the information provided by a plurality of devices. A hard copy input is provided and optically coupled to a hard copy output for producing local copies. A branching device connects the hard copy input to an interface with the external units. A memory is also provided for storing data read from masters, buffering data coming from the external units and for intermediate storage of data during processing operations.
