Abstract
A reciprocative typing control system in which a typing head is driven reciprocally for typing letters at periodic separations in response to a typing signal A following a delay D. A timing signal is produced each time the head is driven by a predetermined distance less than the letter separation and the timing signals counted. In the forward direction a typing signal is produced when the count equals the number of timing signals totaling the separation. In the backward direction the typing signal is produced when the count plus the number of timing signals in delay D equals the number of timing signals totaling the separation.
