摘 要：
PURPOSE: To display prescribed straight line and curve on a projection surface by varying angles of first, second reflection mirrors fixed to its tip for a light beam with the bending of a piezoelectric bimorph and varying the reflection angle of the light beam. ;CONSTITUTION: The first reflection mirror 11, the second reflection mirror 12 are fixed to the piezoelectric bimorph, and are constructed so that motion occurs by the bending of the piezoelectric bimorph. At this time, the motion directions of the reflection mirror 11 and the reflection mirror 12 are different from each other by
90°, beforehand. That is, when the reflection mirror 11 is moved in the vertical direction, the other side reflection mirror 12 is moved in the horizontal direction. For instance, when only the reflection mirror 11 is rotated, the light

beam is deflected vertically, and is reciprocated at a prescribed period
according to a driving frequency. Thus, a straight line is plotted in the direction of a Y axis. Further, when the reflection mirror 11 and the reflection mirror 12 are rotated simultaneously at the same frequency with a phase deference, a circle is plotted.;COPYRIGHT: (C)1995,JPO 主权项：
