(57) A display apparatus adapted to display characters in superscipt and subscript on
a screen. A character generator stores a character font corresponding to superscript
and subscript and excluding insignificant blank data. The character generator is switchable
by a logic circuit between an enable state and a disable state. The logic circuit
produces an enable signal, for example, by deriving a logical product conjunction
of a most significant digit signal of a register for counting the number of rasters
corresponding to one normal size character, a superscript select signal and a subscript
enable signal.
