Abstract

PURPOSE:To make the paper feed toward vertical direction unnecessary, by horizontally and vertically scanning an optical beam through the application of high frequency voltage to horizontal and vertical deflection electrode. CONSTITUTION:The crossing finger electrode 2 is for horizontal deflection and it can move left and right the incident optical beam 6 with the application of high frequency voltage from a high frequency power supply 3 and the radiated light at that time is 8. Further, the crossing finger electrode 4 is for vertical deflection, and the incident light beam 6 can be moved up and down with the application of high frequency voltage from the high frequency power supply 5 and the radiated light at that time is 9. Further, if no high frequency voltage is applied to both the crossing finger electrodes 2, 4, the light is emitted as the outgoing light 7. Further, the horizontal and vertical deflection angles 10 and 11 are controlled with the amplitude of the applied high frequency voltage.
