Document Type and Number:
Japanese Patent JP2004145367
Kind Code:
A
Abstract:

To provide a glass-typed image displaying device that can display a large and bright image and make it smaller and lighter.

The image displaying device installs an optical scanner 5 and an object lens 4 made from a silicon-made movable mirror in one of a temple 9 of glasses, and a prism 3 refracting light, an eyeglass 2 and a cubic beam splitter 1 in the front of the glasses. It promotes the incidence of an optical beam scanned obliquely from the optical scanner 5 into a pupil 7 of an eyeball 6, whereby an image connecting focal points on retina 8 is displayed. An adjusting part changing the interval of two cubic beam splitter 1 can lead the optical beam to both eyes, respectively, thus providing the visible image displaying device and the large image can be seen by making the focal length of the object lens 4 larger than that of the eyeglass 2.
