DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a glasses-type image display device of the present invention. The glasses-type image display device 1 includes a pair of left and right optical blocks 2 and 3 for displaying images. A cover (apparatus housing) 4 in the form of glasses (gokles) to which the lens 3 is attached, and a pair of left and right ear hooks 5, 5 and earphones 6, 6 attached to the cover 4.

The pair of left and right ear hooks 5 and the earphone 6 are attached to the cover 4 so as to be position-adjustable in a state of being integrally connected.

As shown in FIG. 2, the optical block units 2 and 3 include a liquid crystal display (LCD) 11, a backlight 12 disposed behind the display 11, a prism 13, and an eyepiece (aspherical surface). (A lens) 14 so that the image on the liquid crystal display 11 is illuminated by the backlight 12, refracted by the prism 13, and incident on the eyepiece 14.

The optical block sections 2 and 3 are slidably mounted on the cover 4 so as to approach or separate from each other, and turn the lens spacing adjusting dial 15 shown in FIG. 1 in one direction. When the pair of left and right optical blocks 2 and 3 move symmetrically away from each other, the distance between the eyepieces 14 and 14 increases, and when the lens distance adjusting dial 15 is turned in the other direction, the left and right The pair of optical block units 2 and 3 are moved symmetrically in a direction approaching each other, so that the distance between the eyepieces 14 and 14 is reduced.

The eyepieces 14, 14 of the pair of left and right optical blocks 2, 3 are moved in the directions of arrows A, B in FIG. 1 by the diopter adjusting dials 16, 17 shown in FIG. , The diopter can be adjusted.

Next, the cover 4 will be described.

As shown in FIG. 1, the cover 4 comprises a cover body 21 and a pair of left and right side covers 22 and 23 attached to both sides of the cover body 21. Ear covers 5 and earphones 6 are attached to the side covers 22 and 23, respectively.

The side covers 22, 23 are divided into left and right halves 24, 25 as shown in FIG.
A slide guide rail 26 for guiding the slide of the ear hook 5 and the earphone 6 is provided on the inner peripheral surface of one half 25. The other half 24 is opposed to the slide guide rail 26. A long hole-shaped opening window 27 is drilled in a state in which the opening 27 is opened.

The ear hook 5 and the earphone 6 are slidably mounted on the side covers 22 and 23 using the slide guide rail 26 and the opening window 27.

Next, the configuration of the ear hook portion 5 will be described.

The ear hook 5 comprises a vine 31 with one end bent in a U-shape, and a slider 32 provided on the other end of the vine 31.

A rail receiving groove 33 is formed on one side surface of the slider 32. The slider 32 can slide on the slide guide rail 26 by fitting the slide guide rail 26 into the rail receiving groove 33. The slider 32 is repelled by the spring force of a coil spring 34 for operating the slider, slides along the slide guide rail 26, and is pressed against a stopper 28 provided on the half 25. ing.

A bearing piece 35 is provided on the other side of the slider 31 so as to protrude from the opening window 27 to the outside of the half 24. A concave portion 36 for fitting a leaf spring is provided on the side of the piece 35. In the concave portion 36, the earphone 6 is vertically tilted (attached to the ear) or horizontally raised (not mounted). Leaf spring 37 for maintaining in the mounted state)
Is installed.

Next, the configuration of the earphone 6 will be described.

At the upper end of the earphone 6, a pair of left and right bearing pieces 41, 42 are provided.
1 is provided with a convex portion 43 pressed by the leaf spring 37.

Then, the protrusion 43 is connected to the slider 3
2 and the opening window 27
The bearing piece 35 of the slider 32 protruding from the slider 32 is sandwiched between the pair of left and right bearing pieces 41 and 42, and the bearing pieces 35, 41 and 42 are connected by a stepped screw 44. Is mounted to be rotatable.

When the earphone 6 is turned vertically, one side surface of the projection 43 is pressed by the leaf spring 37, and the earphone 6 is pressed against the one half 24 to be tilted vertically. When the earphone 6 is rotated upward by about 90 ° from this state,
The other side surface of the convex portion 43 is pressed by the plate spring 37, and the earphone 6 is pressed against one side surface of the half 24 so as to be kept horizontally raised.

Since the eyeglass-type image display device 1 of the embodiment has the configuration as described above, when the earphone 6 is mounted and used, the earphone 6 is raised horizontally so that the earphone 6 is not in the way. Hang the vine 31 of the hook 5 on your ear,
When the eyepiece 14 is adjusted to the position of the eye, the coil spring 34 expands and contracts, and the positions of the ear hook 5 and the earphone 6 are automatically adjusted.

Thereafter, when the earphone 6 is tilted vertically, the earphone 6 is automatically put on the ear.

The mechanism for adjusting the positions of the ear hooks 5 and the earphones 6 is not limited to the embodiment, and a rack and pinion or the like may be used.

[0031]

The eyeglass-type image display device of the present invention has the structure as described above, and the ear hook portion and the earphone are integrally connected to each other and attached to the cover (device housing) so as to be adjustable in position. The configuration has the following effects.

(1) The work of attaching the ear hook and the earphone to the cover becomes easy.

(2) The position adjustment of the ear hook portion and the earphone can be performed at the same time, and these position adjustment operations are facilitated.
