The first fastening part 190 of the present embodiment includes a fastening rail 173 formed on the housing 171 and the second fastening part 195 is formed on the lower frame 166, And a rail groove 167 slidably engaged with the rail 167. The fastening rail 173 and the rail groove 167 extend in the vertical direction, that is, the z-axis direction, and slide the housing 171 downward to fasten the fastening rail 173 and the rail groove 167.

One end of the rail groove 167 is opened and the other end of the rail groove 167 is closed. The opened end of the rail groove 167 is exposed when the upper frame 165 and the lower frame 166 are separated from each other. . It is possible to slide and fasten the fastening rail 173 along the rail groove 167 from one end of the open rail groove 167 toward the other end.

FIG. 10 is a plan view and a side view showing one embodiment of the wearable device 100 of the present invention, and FIGS. 11 and 12 are plan views illustrating the optic module 170 of the wearable device 100 of the present invention.

Referring to FIG. 10 (a), since the face of the user is a three-dimensional shape, both ends of the face are inclined rearward about the nose. Therefore, the wearable device 100 of the present invention also has a curved surface or an inclined surface inclined to the rear by? On the center of the human face shape. (See Fig. 10 (a)).

The waveguide 153 of the optical module 170 is also preferably arranged side by side with the face of the user and the eyeglass lens 168. The waveguide 153 of the present invention and the optic module 170 are also shown in Fig. In an xy plane, as shown in Fig. Since the image projecting device 151 mounted inside the housing 171 emits light along the extension direction of the housing 171, the light incident on the wave guide 153 in the image projection device 151 is also guided to the wave guide 153 have an incident angle of not 90 °.

There is a problem that it is difficult to accurately calculate the optical path and it is not accurately supplied to the user's eye when the optical waveguide 153 inclines at an angle other than 90 degrees. A prism 180 may be provided between the image projection device 151 and the wave guide 153 so that the image projected from the image projection device 151 is incident on the wave guide 153 at exactly 90 degrees.

The prism 180 reflects the light reflected from the first reflecting surface 181 by the first reflecting surface 181 reflecting the light emitted from the image projection device 151 and transmits the reflected light to the wave guide 153 And a second reflecting surface 182 for emitting an image. The first reflection surface 181 and the second reflection surface 182 face each other but are not parallel to each other in the xy plane so that the angle of the light reflected by the prism 180 differs from the angle of the emitted light.

The first reflecting surface 181 becomes an emitting surface through which the light is supplied to the waveguide 153 as shown in FIG. That is, one side of the first reflection surface 181 reflects the image supplied from the image projection device 151 and the other side passes through the image reflected by the second reflection surface 182 and supplies the reflected wave to the wave guide 153 .

The image incident on the waveguide includes a third reflection surface 1531 that is reflected so as to be bent at an angle total of reflection on the front surface and the back surface of the waveguide and the light reflected on the third reflection surface 1531 is reflected And is reflected and transmitted to the front surface and the back surface of the wave guide 153. And a fourth reflecting surface 1532 disposed at a position adjacent to the user's eyes and changing the angle of the totally reflected light to reflect the wave guide 153 to be supplied to the user's eye.

Referring to FIG. 10 (b), since the person generally looks slightly downward, the lens 168 also tilts downward by θ to fit to the frame 160. The angle formed by the side frame 162 and the lens 168 is inclined forward by 90 degrees with respect to the direction of the gravity direction so that the angle of the side frame 162 with respect to the lens 168 The arrangement of the waveguide 171 and the waveguide 153 can also be arranged so as to be inclined forwardly by an angle θ such as the angle between the side frame 162 and the waveguide 153.

Accordingly, in the form of FIG. 11, the waveguide 153 is inclined downward to be used in the form of FIG. 12, and the optical module 170 is coupled to the housing 171 (or the optical module 170) . The image supply direction of the image projection device 151 and the surface of the waveguide 153 are inclined forward by 90 degrees from the yz plane by θ. As shown in FIG. 12, in the plan view, the housing 171 has an upper surface The waveguide 153 may have a shape tilted forward so that a surface on which an image is incident is seen.

In the embodiment of FIG. 11, the angle between the first reflection surface 181 and the second reflection surface 182 is adjusted by the prism 180 on the xy plane so as to be incident on the wave guide 153 perpendicularly on the xy plane, In this embodiment, it is necessary to adjust the angle on the yz plane. 13, the angles of the first reflection surface 181 and the second reflection surface 182 of the prism 180 are different from each other on the yz plane, The image can be vertically supplied.

13 is a cross-sectional view of the prism 180 of the optic module 170 cut perpendicularly to the first reflecting surface 181 (C-C of FIG. 12).

13A shows a state in which the first reflection surface 181 and the second reflection surface 182 which are arranged in parallel to the z axis are inclined with respect to the wave guide 153 and are inclined to the incident surface of the wave guide 153 / RTI >

13 (b), when the first reflection surface 181 and the second reflection surface 182 are tilted by an inclined angle of the yz axis of the wave guide 153, It is possible to maintain the angle of incidence to 90 degrees. However, since the first reflecting surface 181 serves to reflect light supplied from the image projection device 151 for the first time as shown in FIG. 12, if it is formed obliquely as shown in FIG. 13 (b) There arises a problem that the light reflected by the reflection surface 181 and also the light supplied to the second reflection surface 182 is also distorted.

13 (c), the second reflecting surface 182 is formed obliquely, and the first reflecting surface 181 is disposed side by side with respect to the z-axis. Instead, the second reflecting surface 182 is disposed in parallel with the z- 153 are inclined at an angle of &thetas; ' which is smaller than the tilted angle, so that the light emitted from the first reflection surface 181 can be compensated for further deflection in the normal direction from the normal line. Since the refractive index of the prism 180 is larger than that of air, the light emitted from the prism 180 is bent to the outside of the normal line.

13 (c), the angles of the yz plane of the first reflection surface 181 and the second reflection surface 182 of the prism 180 are also set so as not to be parallel to each other, the image can be vertically supplied to the wave guide 153 inclined by the yz plane?

Fig. 14 is a view showing the coupling relation between the waveguide 153 of the wearable device 100 of the present invention, the prism 180, and the image projection device 151. Fig. Since the waveguide 153 and the image projecting device 151 are not at right angles to each other, the prism 180 is interposed, and in particular, the surfaces of the prism 180 and the waveguide 153 facing each other are not parallel, .

Therefore, the fixing bracket 175 for fixing the prism 180, the wave guide 153, and the image projection device 151 is used. The fixing bracket 175 may include a first portion surrounding the prism 180, a second portion coupled to the image projection device 151, and a third portion coupled to the wave guide 153. The prism 180 may be formed so as to surround the prism 180 excluding the position where the light is emitted from the incident surface of the first partial prism 180 and the second reflective surface toward the waveguide 153. The portion near the entrance surface of the prism 180 is fixed to the image projection device 151 so that the second portion is positioned and the position adjacent to the first reflection surface 181 of the prism 180 is fixed to the wave guide 153 The second part is located.

The second part is fixed to the image projection device 151 with one side by a hook 175d and the other side is fixed to the image projection device 151 by using a fastener 176b such as a screw. The third portion is fixed to the waveguide 153 and the upper and lower portions of the prism 180 except the portion that is incident on the waveguide 153 through the first reflective surface 181 of the prism 180 are substantially light- The wave guide 153 and the third part are fixed to the bar and the fastener 176a.

As shown in FIG. 13, the first reflecting surface 181 of the prism 180 and the wave guide are fixed in a state of being diagonally spaced to prevent a risk that the light path is distorted.

As described above, when the user mounts the optical module only when the optical module is used and when the user does not use the optical module, the user can wear the optical module separately as general glasses, and the waveguide 153, which provides the image to the user's eyes, It is possible to produce a natural appearance because the optic module is not exposed to the other person.

In addition, the angle can be arranged in consideration of the user's head shape and the user's gaze direction, so that the user can appreciate the image at a more comfortable angle.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
