Input device for input of commands into a data processing system

摘要

An input device with a keyboard (10) has a plurality of covering foils (15, 17, 18, 19), which are in the form of exchangeable parts. A code memory (32), in which a plurality of codes (A, B, C) are stored, is provided in a microprocessor-controlled coding device (20). A code which is adapted to the covering foil (15), and converts switching signals of the keyboard (10) into standard signals which a data processing system (42) can use, is set using a code switch (34). What the invention achieves is an input device which can be used universally for a multiplicity of applications. <IMAGE>
