Abstract: Actuation of character keys on a typewriter produce coded pulses that are converted into binary numbers by a programmable memory, representing variations of basic linear widths in accordance with selected printing type styles. The binary number output of the memory controls a pair of counters through a gating section to display a numeric readout representing the accumulated linear width of type of selected height corresponding to the character keys actuated.
