ABSTRACT:
A scanning image displaying apparatus capable of preferably adjusting a diopter is disclosed. The scanning image displaying apparatus includes a light source, a movable diffusing face, an imaging optical system for forming an image of the light source on the diffusing face, scanning means for two-dimensionally scanning the image of the light source formed by the imaging optical system on the diffusing face, an eyepiece optical system for guiding light from the diffusing face to an observer, and a mechanism for moving the light source and/or at least a portion of the imaging optical system in interlocking relationship with the movement of the diffusing face.
