Abstract
Character information to be displayed is stored in a temporary memory. Character data (ASCII code) is provided from the temporary memory to a character generator. The character generator is responsive to the character data to convert them into a dot display signal displaying each character in m columns and n rows. Then the display signal of each common row of the respective characters is transferred to a shift register in a bit serial fashion. Each time the display signal for one character is transferred a display blank signal is loaded in the shift register. A dot matrix display comprises rows of the same number as the cells of the shift register for producing a blank of one column between the adjacent characters, while displaying each character in m columns and n rows. After display is made on the display for all the rows, a leftward shift is made in succession one column by one column from the lowest row. When the shift amount comes to correspond to one character, new character information is loaded in the temporary memory.
