| Abstract: |
In order to facilitate pupil distance adjustment, diopter adjustment and convergence adjustment, in a spectacle type display arrangement which utilizes of a pair of image generating units for projecting images on left and right eyes respectively, a pair of shafts are installed in a housing by way of a frame, and a pair of lens and mirror units are reciprocally mounted on the shafts so as to movable toward and away from each other. A slide plate which forms part of a backlight is disposed on the frame so as to be slidable in the fore-and-aft direction. A pair of shafts are disposed one above the other at the upper and lower portions of the backlight. A pair of LCD holders which form a part of the pair of image source means are supported on the shafts so as to be laterally movable toward and away from each other. A pupil distance adjustment of the pair of image generating means is implemented by a rotation of a knob 8 through cam and link mechanisms, while a diopter adjustment and a convergence adjustment are simultaneously implemented by a rotation of a knob through a separate cam mechanism.

What is claimed is:
1. A spectacle type display device substantially enclosed in a housing and arranged to transmit images generated by a pair of image sources along a double folded optical path by way of a pair of image transfer units, each of which includes a reflection plate and an ocular lens, and a reflecting means positioned to receive images from the image transfer units and to project the images on retinas of the left and right eyes of a wearer, and which comprises:
- a first support and linkage means for supporting and linking said pair of image transfer units so as to be laterally movable toward and away from each other, said first support means including a rail on which said image transfer units are slidably supported, and
- second support means for supporting said pair of image sources for lateral movement toward and away from each other and cojointly for movement in a fore-and-aft direction relative to the reflection plates and the ocular lenses of said image transfer means.
