ABSTRACT:
In a display device having a record medium which is parallel-line raster scanned by a beam which is intensity modulated to form matrices of dots representing symbols, apparatus is provided to generate composite symbols such as characters with diacritical marks. The apparatus includes a source of groups of coded combinations of bits representing symbols with each group having a first part representing the character and a second part the diacritical mark. A first addressable memory stores the binary signals representing the dots of the character while a second addressable memory stores the binary signals representing the dots of the diacritical marks. Thus, each symbol group addresses two memories which then feed these binary signals to the beam which is intensity modulated to form a matrix of dots on the record medium. In addition provision is made to vertically displace the characters to perform subscripting and superscripting.
