ABSTRACT:
A character font generating apparatus comprising character ROM for storing font data of a character in a form of a plurality of horizontal lines each of which consists of a predetermined number of dots, a shift register with a data storing portion including the same number of flip-flops as the predetermined number, which stores data in parallel in response to a storing timing signal and outputs the stored data in serial in synchronization with a transfer clock signal, italic generation timing circuit for generating storing timing signals to be supplied to the shift register such that each of the storing timing signals is generated for each horizontal line of the font data stored in the character ROM on a different timing from timing of the other storing timing signals with respect to a time when a scan of a line is started, and display control circuit for controlling a data transfer from the character ROM to the shift register such that dot data of each horizontal line of a font data stored in the character ROM is transferred to the data storing portion of the shift register for storing the dot data into the storing portion in parallel based on a storing timing signal generated by the italics generation timing circuit.
