Abstract
In an image recording or displaying system using a light beam scanning means, format lines are generated in combination with character data to be recorded or displayed together therewith. A format line data memory memorizes the format line data and the output format line data read out therefrom are combined with the character data. The format line data memory is provided with a horizontal pattern memory and a vertical pattern memory. The horizontal pattern memory memorizes various horizontal patterns in the direction parallel to the scanning line of the light beam scanning means. The vertical pattern memory memorizes the kind of the horizontal pattern according to the position of the scanning line. The vertical pattern memory generates the horizontal pattern code according to the scanning line signal and the horizontal pattern memory generates the selected horizontal pattern for every scanning line.
