Abstract
PURPOSE: To expand a character pattern without increasing a memory for pattern generation by generating an expanded parttern easy to see by the naked eye and then by changing a normal pattern over as occasion demands by attaching a few circuits to the output of a normal pattern generator.
CONSTITUTION: Dot information (c) read out from basic dot pattern generator A on a dot matrix system in sequence is supplied to selector K receiving mode selective MD, thereby outputting pattern output signal (m) when signal MD is a normal signal. For the purpose of outputting an expanded pattern, latch circuit B which receives dot information (c) generated by generator A, latch circuit C which receives the output of circuit B, X and Z-directional supplementation circuits D and E, selectors F, I and J, and Y-directional supplementation circuit H; and a supplementary dot is inserted between basic dots in the Y direction and slanting direction and selector K changes the normal pattern over to the expanded pattern, which is outputted.
