<p>PURPOSE:To permit drawing of any kinds of vectors as well by using a thermal printer as an XY plotter. CONSTITUTION:The output of a vector data circuit 13 is accumulated and stored in a memory 24 and a memory 25 via a memory selecting circuit 23. The outputs of the memories 25, 25 are fed directly or if necessary via a memory alternating circuit 26 to an X difference circuit 27 and a Y difference circuit 28. The circuit 26 operates when the output of the circuit 27 goes negative, thereby alternating the data of the 1st memory 24 and the data of the 2nd memory 25.</p> |
