２に外装部１ｃを固定すればよい。Since the first embodiment is constructed as described above, when the image display device is mounted on the head, first, the both side portions 2b of the hair band 2 are spread by hand and the respective ends of the both side portions 2b are first spread. Release the hand so that the part is behind the ear D. At this time, the hair band 2 tries to return to the state shown by the solid line in FIG. 5 due to its own habit, so that the inner surface of the top portion 2a contacts the observer's crown Ba and the both sides thereof reach the observer's head. Press against the side of the part. In this state, in the eyeball projection device 1, the left and right cheek pads 3 and 3 respectively contact the left and right cheeks Cd and Ce of the observer, and the nose pad 4 abuts on the bones of the observer's nose Cc to obtain a substantially predetermined amount. However, the diopter correction lens 1b of the projection optical system 1b is located at the position of the eyeball projector 1.
When the optical axis of 3 and the center of the eyeball Ca are deviated, the screw 5 at the connecting portion between the hair band 2 and the exterior portion 1c of the eyeball projection apparatus 1 is loosened to move the eyeball projection apparatus 1, and the eyeball Ca is connected. The exterior part 1c may be fixed to the hair band 2 by tightening the screw 5 at a position where the optical axes of the image lenses 1b 3 are aligned and the eyeball projector 1 is stably mounted.

きる。Thus, the weight of the entire eyeball projection device 1 is subject to the pressing force at both ends of the hair band due to the force of the observer A's crown Ba and the tendency to bend the hair band 2 inward. A rear side of ear D of A and pads 3 for left and right cheeks
3 is supported by the left and right cheeks Ce, Cd of the observer A with which the object 3 hits. This is schematically shown in FIGS. 6 and 7. That is, the weight of the entire eyeball projector 1 is equal to the arrows A 1 , A
It is dispersedly supported as indicated by 2 and A 3 . Each of the left and right cheek pads 3 and 3 is arranged in the rotation direction of the eyeball projection device 1 (the direction of the broken line arrow in FIG. 7) around the contact portion between the top portion Ba of the observer A and the top portion 2a of the hair band 2. since will support half that pushing force represented by the arrow a 3 of the pressing moment, the component force a component force b of the relatively large and the vertical direction to the face direction can is relatively small.

的に装着位置に保持され得る。Therefore, in the conventional head-mounted image display device, not only is the ear D heavily loaded, but the entire device is likely to shift downward, resulting in discomfort to the observer. On the other hand, according to the first embodiment, the entire device is supported by the head and the projecting parts of the face such as the cheeks and the nose and is not displaced downward, so that the device position is stable, It does not cause any discomfort. Further, since the cheek pad 3 and the nose pad 4 are made of an elastic body and the elastic pads 2c are provided at both ends of the hair band 2, the interference between the head B and the device 1 is reduced. The wearing feeling can be improved, and since the left and right cheek pads 3 and 3 block external light from below the device, a clear image can be enjoyed. Since the entire eyeball projector 1 is rotatable around the screw 5 at the connecting portion with the hair band 2, the entire device should be rotated to the position of the chain line in FIG. It is possible to use it, and its practical usability is extremely good. In the first embodiment, as shown in FIG. 7, the parietal region Ba is the normals N 1 and N 2 that are set up on the circular arc of the head with the observer A facing straight forward with respect to the vertical line. ± 45
According to the experiment, if the top portion 2a of the hair band 2 is within the above range, the hair band 2 will not be displaced and the eyeball projector 1 can be stably mounted. Can be held in position.
