    摘要: The invention is intended to provide a three-dimensional image projecting device which is capable of presenting a three-dimensional image observable in a wide visual field without tiring eyes of an observer. A three-dimensional image displayed by three-dimensional image displaying means is projected by a reflection type projecting hologram lens and reflection type hologram acting as optical transferring means and a reflection type hologram lens to produce respective three-dimensional images. These three-dimensional images are formed at the same magnification in the same space to form a continuous image area. For this purpose, reflection type hologram lenses are disposed on the periphery of a circle. Respective three-dimensional images is reflected by the reflection type hologram acting as the optical transferring means, thus an enlarged three-dimensional image can be seen over the respective visual fields.
