Abstract
A control method controls a sheet-driven type automatic drafting machine to allow for drying of an inking medium disposed on a drafting sheet. The automatic drafting machine is of a type which includes a platen upon which a drafting sheet is conveyed in a feed direction and a line-drafting head which is conveyed in a line direction perpendicular to the feed direction. The line-drafting head is adapted to accommodate at least one writing instrument from among a plurality of writing instruments located in a stocker. The control method includes a step of storing in a memory a drying time associated with the inking medium of each of the plurality of writing instruments, a step of determining which of the plurality of the writing instruments is accommodated by the line-drafting head, a step of reading from the memory a drying time associated with the one of the plurality of the writing instruments accommodated by the line-drafting head, and a step of controlling the conveyance in the feed direction of the drafting sheet in accordance with the thus read drying time. The identity of each writing instrument is determined by either sensing an identification mark on the writing instrument or by referencing a location of the writing instrument within the stocker.
