Abstract

PURPOSE: To secure the smooth oblique line area for the magnified character as well as to eliminate the oblique line thickening by installing the means to secure the proper thickness for the oblique line in the magnifying correction of the character, and thus to enhance the character quality for both print and display.
CONSTITUTION: The dot data read out of memory 4 enter by one line shift register SR1 in the double magnified character generator and then shifted by one bit to enter in sequence the 3-bit/3-step register of the pattern detector circuit as well as SR2 and 3. With end of the 1-line shift, the next line enters SR1. In the 3-bit/3-step register, dot patterns (a)W(x) are detected with every shift. When the coincident patterns exist, the corresponding patterns are sent out; while the original dot is turned to the 4-dot to send it out if no coincident patterns exist. The 48-line/48-row pattern 50 is obtained by magnifying fundamental character 40 of 24-line/24-row. Thus, the oblique strokes of the characters become free from coarseness and at the same time are thinned
