Abstract
Abstract An electrical code-signal generator system for operation from a keyboard having a plurality of pulse generating keys comprises a plurality of input lines for individually receiving pulses from the keys, a normally enabled gate in each of the input lines, a code generator having a plurality of input circuits individually coupled to the gates and having a first plurality of data output lines on which appear character-representative encoded signal pulses. The generator system further comprises a first shift register coupled to the data output lines, a second shift register coupled to the first shift register and having a second plurality of data output lines and a plurality of AND gates individually included therein, and a punch and connected driving motor which develops a cyclical signal representative of and isochronous with its operating cycle. The generator system further includes an OR gate responsive to the first signal occuring on the first data output lines for developing a clock pulse commencing a predetermined interval thereafter and a circuit for applying the clock pulses to the first register for transferring data from the code generator to the output of the first register and thence to the input of the second register, a sync-logic unit jointly responsive to the clock pulses and to the cyclical signal for enabling the AND gates included in the second data lines for transferring data from the AND gates to the punch and for inhibiting all of the gates in the input lines for a minimum interval, of the order of 1 Mu sec, after actuation of a given key and until any data in the second shift register has been utilized by the punch.
