Filed: 1986-06-09
Abstract: PURPOSE:To sharply widen the deflection angle of an optical deflector element, by further deflecting twice a light beam which is deflected by the impression of a signal voltage by means of a recessed surface. CONSTITUTION:A laser beam 20 emitted from a laser light source 3 is made incident to the auxiliary prism 1 of an optical deflector element 5 after passing through a chopper 4 which is controlled by a driving device 9. The laser beam 20 is further made incident to a deflecting prism 2 from a surface of separation S1 at an incident angle of phi deg.. If a signal voltage is impressed across the optical deflector element 5 from a signal voltage impressing device 7 through a driving circuit 6 which is controlled synchronously to the chopper 4 in this state, the laser beam 20 is refracted by an angle theta deg. at the surface of separation S1. Under the condition where no signal voltage is impressed, the laser beam 20 advances in a beeline in the direction of the dot line 21. The deflection angle of the laser beam 20 deflected in accordance with the intensity of the electric field produced by the signal voltage impressed after passing through the surface of separation S1 becomes about 10 deg. and the laser beam 20 deflected by the deflecting prism 2 is further refracted by a recessed emitting surface S2. Thus the laser beam 20 is widened in deflection angle and transmits picture information onto a photosensitive drum 8.
