ABSTRACT:
A character code storage device stores character codes together with display permission information (display levels) attached to every character code. A font data storage device stores font data together with display level values attached to every dot constituting a font. A dot-display-value synthesizer synthesizes these two data and controls dot-display for representing a character according to two kinds of information--display permission information and display level values. The display permission information from a display-permission-value register is reflected at every display level value of dots constituting a font corresponding to the character. When each dot is read from a display circuit, its display level value is also read out and transferred to a display control unit. The transferred dot is compared with a display-permission-level value stored. Dot data which does not meet the condition will not be sent to the display circuit. Consequently, this dot is masked.
