PROBLEM TO BE SOLVED: To display images (virtual images) on a plurality of surfaces displaced in a depth direction by one projector.SOLUTION: A virtual image generation unit 25 is arranged on an optical path of second projection light L2 (first projection light L1) between a display unit 23 and a second screen 12 (first screen 11), and generates a virtual image on a first display area of a display unit 23 generating the first projection light L1 and a virtual image on a second display area of the display unit 23 generating the second projection light L2, closer to a projector lens 24 than the first display area and the second display area of the display unit 23. In the virtual image generation unit 25, a second virtual image generation unit through which the second projection light L2 transmits is thicker than a first virtual image generation unit through which the first projection light L1 transmits. The projector lens 24 images as real image the virtual image on the second display area in a position away from the virtual image on the first display area.SELECTED DRAWING: Figure 2

    【課題】1つの投影器で奥行き方向にずれた複数の面に画像(虚像)を表示する。【解決手段】虚像生成部25は、表示器23と第二のスクリーン12(第一のスクリーン11)との間の第二の投影光L2(第一の投影光L1)の光路上に配置され、第一の投影光L1を生成する表示器23の第一の表示領域の虚像と、第二の投影光L2を生成する表示器23の第二の表示領域の虚像とを、表示器23上の第一の表示領域及び第二の表示領域よりも投射レンズ24側に生成する。虚像生成部25は、第二の投影光L2が透過する第二の虚像生成部の厚さを、第一の投影光L1が透過する第一の虚像生成部の厚さよりも厚くする。投射レンズ24は、第二の表示領域の虚像を、第一の表示領域の虚像よりも離れた位置で実像として結像する。【選択図】図2
