Abstract

PURPOSE:To prevent a pattern displayed from varying in size, by providing a convex lens in the path of a laser light beam so that a screen will invariably be a focus surface. CONSTITUTION:Screen 27 and convex lens 34 are fitted to sliders 18 and 19 by supporting frame 35 at an interval of focal length (f) of convex lens 34, and convex lens 34 and screen 27 move integrally according to the reciprocating motion of sliders 18 and 19. In this three-dimensional display device, laser beam 26 of parallel light deflected by light deflectors Dx and Dy irradiates screen 27 via concave lens 34, and consequently screen 27 is displaced, so that even if distances between screen 27 and light deflectors Dx and Dy will vary, a two-dimensional pattern drawn on screen 27 will not vary in size according to variations in distance.
