ABSTRACT:
A character pattern signal generator for generating a signal corresponding to a character being formed as a plurality of dots forming an outline body includes an outline memory for storing character code data corresponding to an outline of a standard size character. An outline data calculating circuit receives the outline data and a magnification signal and calculates character outline data in response thereto. A dot pattern generating circuit converts said character outline data into dot pattern data representing the character outline. A dot pattern compensating circuit detects a number of dots separated by a space from the body of the character outline and compensates the dot pattern data by a number of dots to be added to the dot pattern data at the space when the magnification factor is less than one and the number of dots is less than a predetermined value.
