PURPOSE:To display Lissajou's curves effectively with a simple constitution by mounting plane mirrors with slight inclinations from right angle to the revolving shafts of motors and disposing a plurality of such laser scanning elements. CONSTITUTION:A plane mirror 7 is mounted with a slight inclination from right angle to the revolving shaft 6 of a motor 5 to provide a laser light scanning element. A plurality of these laser light scanning elements are disposed and plane mirrors 22, 23, 24, 25 are respectively mounted to the same motors 10, 11, 12, 13. If the speed control of the motors is done by changing the input pulses of stepping motors, the scanning speeds of laser light may be changed and various Lissajou's curves may be readily obtained according to these. This device is simple in constitution and is easy to manufacture and if this is used as a display, large effect may be obtained. |
