Abstract
PURPOSE: To increase the display speed of a display device by storing addresses corresponding to display character codes in a display character address storage memory. CONSTITUTION: A display character address storage memory 15 where addresses converted by a code address computing element 12 are stored, a display controller 17 which takes out display character addresses corresponding to display character codes from the display character address storage memory 15 and takes out display character bit patterns corresponding to display character addresses from a character generator 13 to store them in a refresh memory 21, and a display device 22 on which display character bit patterns stored in the refresh memory 21 are displayed are provided. If addresses corresponding to display character codes are preliminarily stored in the display character address storage memory 15, it is unnecessary to take out display character codes from the display character code storage memory again even at the time of switching operation of plural pictures and scroll operation. Thus, the display speed of the display device is increased.
