Abstract A KEYBOARD ENCODER COMPRISES A SET OF KEYS. EACH KEY IS IN JUXTAPOSITION WITH ONE OR MORE FIELD-RESPONSIVE ELEMENTS ASSOCIATED WITH THAT KEY, THE OUTPUTS OF THE FIELD-RESPONSIVE ELEMENTS BEING CONBEYED TO OUTPUT TERMINALS OF THE ENCODER. ACTUATION OF KAY ALTERS THE FIELD TO WHICH THE ELEMENTS ASSOCIATED THEREWITH RESPOND. THE NUMBER OF ELEMENTS ASSOCITATED WITH EACH KEY AND THE CONNECTIONS OF THESE ELEMENTS TO THE OUTPUT TERMINALS CORRESPOND TO THE OUTPUT CODE FOR THE CHARACTER REPRESENTED BY THE KEY. CONSEQUENTLY, THE RESPONSES OF THE FIELD-RESPONSIVE ELEMENTS TO ACTUATION OF A KEY PRO- VIDE A DIRECTLY ENCODED REPRESENTATION OF THE CORRESPONDING CHARACTER AT THE OUTPUT TERMINALS.
