摘要
Since the present invention includes a character pattern ROM 7a having no memory of upper and lower space data lines, there is an address determination circuit 28 and a selection circuit 29, and when a value of an address signal L is not within an actual memory range from "3" to "16", the address determination circuit outputs a false signal as a determination result upon which the selection circuit outputs character pattern lines each including only extra space data, so that it is possible to serve a similar function to that of a conventional one with a smaller memory capacity than that of the conventional one.
