Abstract
PURPOSE:To produce enlarged letter, reduced letter and deformed letter, without increasing pattern memory capacity, by controlling laser scanning speed or scanning interval on a sensitive medium. CONSTITUTION:A laser beam RB oscilated from a laser oscilator 1 enters a rotary multi-face mirror 5 through a reflection mirrors 2 and 2', a modulator 3 and a horizontal-and-vertical deflector 4. When a deformed letter commanding signal MC issued an instruction to such an effect as to print m/2 pieces of letters (m pieces of standard letters) on a line by increasing sizes by 2 times in horizontal direction and decreasing by 1/2 times in vertical direction, a speed commanding unit 15 gives a signal RC to a rotating speed control circuit 9 to such an effect as to double rotating speed of the rotary multi-face mirror 5. At this time, if dot pattern read-out speed is set to the same speed as the case of the standard letter, all the letters are increased by 2 times in the horizontal direction and reduced by 1/2 in the vertical direction, and thus formed image is shown on a drum.
