To provide an image projection device with which, while saving space using a common image irradiation unit and a free-form surface mirror, yet it is possible to differentiate the image forming positions of a plurality of virtual images.SOLUTION: Provided is an image projection device (10) that irradiates a display unit (6) for displaying a virtual image with a projection image, and that comprises an image irradiation unit (1) that radiates first image light (L1) and second image light (L2), and an irradiation optical system that radiates the first image light (L1) and the second image light (L2) in a viewpoint direction via the display unit (6). The irradiation optical unit includes an image-forming position adjustment unit (4) that causes a difference in image-forming position of the virtual image between the first image light (L1) and the second image light (L2).SELECTED DRAWING: Figure 1
【課題】共通の画像照射部と自由曲面ミラーを用いて省スペース化を図りながらも、複数の虚像の結像位置を異ならせることが可能な画像投影装置を提供する。【解決手段】虚像を表示するための表示部(6)に対して投影画像を照射する画像投影装置(10)であって、第1画像光(L1)および第2画像光(L2)を照射する画像照射部(1)と、表示部(6)を介して第1画像光(L1)および第2画像光(L2)を視点方向に照射する照射光学部を備え、照射光学部は第1画像光(L1)と第2画像光(L2)の間で虚像の結像位置に差を生じさせる結像位置調整部(4)を備える。【選択図】図1
