Further, in order to eliminate the disturbing code, an antenna may be connected to receive a signal from the outside by radio waves.

An explanation will be given of the usage when the observer wears or withdraws the image display device of this embodiment having such a configuration. First, the observer puts his or her finger on the finger rest 8 and spreads it outward to expand the space formed by the left and right rear plates so that the head can be easily inserted. And
After the head is inserted, the crown pad 20a and the display body 1 are aligned with the head as a reference, and the finger is put on the finger 8 and removed. As described above, the rear cover 6 is the rear plate 5 made of an elastic body.
Since the rear plate 5 is joined to the rear plate 5, the rear plate 5 presses and supports the observer's head from the rear. Next, the LCD 12 in the display body
The adjustment member 18 is moved up and down so that the eyeball position of the observer and the exit pupil formed by the prism 15 coincide with each other on the basis of the image from or the light from the outside. By this operation, the band 1 attached to the adjusting member 18
7 expands and contracts, and the parietal cover 20 interlocks therewith and moves up and down, whereby the display main body moves up and down relatively to the observer's eyeball position, and adjustment is possible.

The speaker 9 can be fitted to the observer's ears by rotating the speaker support 10 to the left and right. In addition, when leaving the device,
Since the rear cover 6 can be removed by expanding the rear cover 6 with the finger rest 8 again, the insertion and removal can be performed easily and smoothly. Furthermore, since the crown frame 4 is in the shape of a square, the dead space is reduced, which contributes to downsizing.

Further, since various wirings such as the cable 22 are embedded in each frame, the wiring is crushed between the apparatus and the desk when the apparatus having the exposed cable or the like is left on the table, for example. It is possible to reduce the damage received from the outside, and since the appearance is not spoiled, the degree of freedom in design is increased. Further, since the finger pad 8 is made of rubber, a slip preventing effect can be obtained.

Further, the U-shaped groove 1 of the speaker support 10
Since 0a is formed in a Y shape, it can be formed as a common part that can be used on either the left or right side, and thus it is excellent in mass productivity and can contribute to cost reduction. Along with that, since the speaker cord 11 is embedded, the stress applied to the intersection of the Y-shaped portion of the U-shaped groove 10a when the speaker supporting body 10 is rotated makes the Y-shaped angle α acute. Therefore, it can be dispersed and the durability can be improved.

Since each pad (7a, 20a) is formed of urethane foam, the stress generated by the pressing force for supporting the head can be absorbed and dispersed, and the pain and discomfort caused by the contact portion of the observer at the time of wearing the pad can be absorbed. Can be relaxed,
Can be worn comfortably. Further, since the crown cover 20 has a curved shape, the crown pad 20a can also absorb and disperse the stress by the similar curved shape, and can further alleviate the discomfort or the like occurring at the crown of the observer. (Embodiment 2) Embodiment 2 of the present invention will be described with reference to FIG. For the sake of simplicity, the same members as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, the rear plate 5 is attached so as to straddle the front frame 2 and the rear frame 3.
Therefore, the connecting plate 23 is attached to the mounting portion of the rear plate 5.
Are provided and fixed to the front frame 2 and the rear frame 3 by screws or the like. In addition, since the display body 1 has various optical systems (12, 13, 14, 15, 16) built therein, the weight tends to be heavy. Therefore, the indicating force applied to the crown frame 4 becomes large. Therefore, in this embodiment, the parietal frame 4
The protruding portion 24 is provided so as to extend in the direction of the display body 1 to enhance the holding force. Further, by adding the protruding portion 24, it is possible to slide the rear frame further in the front direction of the observer's head. In that case, the opening of the observer's occipital region can be made larger. Even when the head of the sofa or bed is sunk when worn, it is possible to further reduce the risk of the device touching and disturbing.

Further, since the rear cover 6 is opened by using the finger pad 8 and the device is inserted and removed, the joint surface between the finger pad 8 and the rear cover 6 may easily come off. Therefore, a device is devised in which the overlapping portion of the finger pad 8 and the rear cover 6 is provided and the surface is used as the joint surface. The structure is such that the rear cover 6 has a boss 25.
The finger contact 8 is provided with a hole at a position corresponding to the boss 25, and the cross-sectional shape cut in the thickness direction is L-shaped. With this configuration, the force applied to the finger rest 8 does not move because the hole formed in the finger rest 8 interferes with the boss 25 provided on the rear cover 6, and therefore the force is not easily removed and the strength can be improved. Furthermore, since the locking force is applied by the boss 25 provided on the rear cover 6 as described above, the joining means may be a simple joining means, in which case the productivity can be improved and the assembly time can be shortened.

In the first or second embodiment, the adjusting means for the electric component 21 and the adjusting means for video and audio as described below may be provided. The configuration will be described below with reference to FIG.
This will be described with reference to (a) and FIG. 7 (b). FIG. 7A is an enlarged view of the parietal frame 4, and FIG. 7B is a view of the unit plane portion of the parietal frame 4 looking up from the observer's head storage space side.

The electrical component 21 includes an amplifier in addition to various circuits.
Devices such as tuners are also built-in, and adjustment may be necessary in some cases. In addition, if the color balance of the image, the volume of the sound, the sound quality, and the like can be adjusted, more realistic viewing can be performed. Therefore, it becomes necessary to provide various adjusting means. However, it is not preferable in appearance that the various adjusting means are provided on the surface of the apparatus. Therefore, a structural feature of the crown frame 4 provided for improving the wearing property, that is, by lowering the adjusting member 18, the crown cover 20 via the band 17 is provided.
Paying attention to the fact that the space between the parietal frame 4 and the parietal cover 20 is lowered, various adjusting means for the electrical component 21 are provided on the back surface of the unit plane portion of the parietal frame 4. The configuration of the various adjusting means controls the contrast adjustment and the color balance of the image by adjusting the voltage of the electrical component 21. Therefore, the internal connector 26 that receives the signal for adjusting the voltage is provided on the top frame 4. It is provided on the back surface of the unit flat surface part. Then, an external connector 2 configured to connect a control signal from an external controller (not shown) to the internal connector 26 via a cord 28.
7, the voltage of the electric component 21 can be adjusted via the internal connector 26.

Further, in addition to the internal connector 26, an image adjusting knob 29 and a volume adjusting knob 30 may be provided so that the image display density of the LCD 12 and the volume of the speaker 9 can be adjusted. In this case, each adjustment is performed by rotating the knob, but the convex knob protrudes from the parietal frame 4 and thus becomes an obstacle when the observer wears it, or an image that is accidentally touched by the knob is adjusted. There is also a risk of breaking the voice. Therefore, it is desirable that the image adjusting knob 29 and the volume adjusting knob 30 have a concave shape that is embedded in the back surface of the crown frame 4 through a hole. If the end face shape of the image adjusting knob 29 or the volume adjusting knob 30 is provided with a groove of one character or a cross, and a minus or plus driver is inserted into the groove and rotated, the space is excellent and the wearer can wear it. The risk of causing a malfunction can also be avoided.

The observer has a different head shape depending on sex, age, race, etc., and in order to improve the wearability, the device must have a shape adapted to each observer. . However, it is not desirable because it must be created individually to be fully adaptable, which is costly and time consuming. Therefore, the present invention can be applied to a wider variety of head shapes by variously changing the shapes of the crown cover 20 and the crown pad 20a as in the above-described embodiment, and the wearability can be improved. Is possible.
