Abstract
A control method for a paper-driven type automatic drafting machine carries out a predetermined drafting operation by use of ink writing instruments. The automatic drafting machine has on its machine frame an ink dry time setter. The machine is made to wait or halt for a set time after an ink drawing completion, during which time a roll paper for the drafting machine is not rolled-up. The remaining portion of the set ink drying time for the drafting machine is displayed, so the operator can use the waiting time effectively.
