Abstract: PURPOSE:To enable respective columns forming left and right vertical lines to be reduced to a left and right symmetrical form, by a method wherein the column number in the last time is advanced by one, or otherwise operation is performed by using a font data of the following column number, and the column number to operation thereafter is set. CONSTITUTION:When a count value judging circuit DCT judges that a value of a counter CT becomes, for instance, 4, through an address counter hithertoadvanced the column number by 2 every time the counter CT counts 1, it now advances by 1. That is, when a logical sum (X0)+(X1) of a font data of A=7 and A=8 in an address of a ROM is stored in a RAM, and a value of the counter CT at that time is 4, the counter DC is decremented without incrementing the address of ROM by the address counter ADC, and this operation is repeated. Then, a set of an odd number and an even number advancing the number of a column in operation of a former logical sum becomes the set of even and odd number in the latter logical sum, and two vertical lines of a character 'H' are respectively formed by one column to obtain a left and right symmetrical character.
