ABSTRACT:
For use in a character display device, a modifying device comprises first and second memories. The first memory memorizes a character code representative of a character which should be displayed. The second memory memorizes an attribute or characteristic code and a selection code which cooperatively determine modification of the character. The character code, the attribute code and the selection code are read out of the first and the second memories by an address signal which is supplied from a supplying section. Responsive to the character code, a character pattern generating circuit generates a character pattern to supply the character pattern to first through N-th modifying circuits, where N represents a positive integer which is not less than two. Responsive to the attribute code, the first through the N-th modifying circuits modify the character pattern into first through N-th modification signals, respectively, to supply the first through the N-th modification signals to a selecting circuit. Responsive to the selection code, the selecting circuit selects at least one of the first through the N-th modification signals as a modified signal representative of the character with modification.
