It is a figure which shows the electric board incorporated in the housing | casing of a main-body part, and the eyepiece optical part in a light guide part with the position of an eyeball, FIG. 3 (a) is a side view, FIG.3 (b) is a top view.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIGS. 1A and 1B are diagrams illustrating a state in which a glasses-mounted display device according to an embodiment of the present invention is mounted on glasses, in which FIG. 1A is a side view and FIG. In the following description, front, back, top, bottom, right, and left are the front, back, top, bottom, and front, as viewed from the wearer, with the glasses-mounted display device mounted on the head of the wearer. It shall mean each direction of right and left. Therefore, the front-rear direction is a direction along a substantially temple of the glasses (so-called front direction), and the left-right direction is a direction connecting the left and right hinges of the glasses (so-called side).

  As shown in FIGS. 1 (a) and 1 (b), the glasses-mounted display device 1 is of a type that displays an image on the right eye, and includes a rod-shaped main body 3a, a rod-shaped light guide 3b, A housing 3 is provided.

  On one side surface of the main body portion 3a, two fixing portions 2a and 2b for attaching to the temple 10a of the glasses 10 are provided. The fixing portion 2a is arranged near the rear end portion in the longitudinal direction (extending direction) of the main body portion 3a, and the fixing portion 2b is arranged near the center in the longitudinal direction of the main body portion 3a. Grooves are formed in the fixing portions 2a and 2b, and the temple-mounted display device 1 is fixed to the temple 10a by sandwiching the temple portion 10a of the glasses 10 in the grooves. In this way, the glasses-mounted display device 1 is stably supported by fixing at two locations.

  As shown in FIG. 1A, the longitudinal direction of the main body 3a is preferably arranged substantially parallel to the temple 10a so that the rear portion of the main body 3a extends along the temple 10a when attached to the glasses 10. By making the center line substantially parallel to the temple 10a, support at two or more locations is facilitated, and the glasses-mounted display device 1 can be firmly fixed to the glasses 10. On the other hand, the front portion of the main body 3a is inclined obliquely downward. A portion where the center line located on the rear side of the main body portion 3a is along the temple is referred to as a first portion 4a.

  The main body 3a includes a display panel 7 for displaying an image and an electric board 6 of an electric circuit for driving the display panel 7 (see FIG. 3). The display panel 7 is disposed in the vicinity of the distal end portion of the main body 3a. The display panel 7 and the electric substrate 6 will be described later with reference to FIG.

  The light guide 3 b guides the display image from the display panel 7 to the front of the eyeball 11 of the wearer and emits the image from the image light emitting unit 5 toward the eyeball 11. For this reason, the light guide portion 3b extends from the front end portion of the main body portion 3a to the front side of the lens 10c along the lens surface of the lens 10c of the glasses 10. As shown in FIG. 1A, when viewed from the left-right direction (side), the light guide portion 3b is linearly connected to the bent portion on the front side of the main body portion 3a. For this reason, the image light emitting unit 5 faces the surface of the lens 10c slightly below the center of the lens 10c. The front side portion inclined obliquely downward of the main body portion 3a and the light guide portion 3b constitute a second portion 4b.

  Since the first portion 4a and the second portion 4b are configured by one housing and the inclined portion is fixed, it is possible to display an image at a position that is stable and easily visible without adjustment. . Moreover, since there is no moving part, a complicated mechanism is not required, and the device can be made small and hardly damaged.

  Further, as shown in FIG. 1A, when the housing 3 is viewed from the side surface in the left-right direction of the glasses, the first portion 4a is located at a position where the temple 10a of the glasses 10 is hidden, and the second portion 4b is located below the armor 10d of the glasses-mounted display device. By fixing the glasses-mounted display device 1 to the glasses 10 such that the first portion hides the temple 10a, the glasses-mounted display device 1 can be more firmly fixed to the glasses 10. The entire device can be made small. Further, by arranging the second portion 4b of the housing 3 at a position where the armored portion can be seen upward, the display image can be displayed at a position where it can be easily seen, and interference with the armored 4d and the rim 4e can be avoided.

Further, the bending point P ₁ between the upper surface portion of the first portion 4 a and the upper surface portion of the second portion 4 b of the housing 3 is closer to the ear side than the hinge portion 10 b of the glasses 10. By setting it as such a structure, the interference with the housing | casing 3 and the armor 10d of the spectacles 10 can be avoided.

Hereinafter, including the center line of the first portion 4a, the first plane S ₁ a plane parallel to the lateral direction of the spectacles. First plane S ₁ is a horizontal plane including the center line of the first portion 4a of the housing 3. The second part 4b, i.e. including the center line of the portion that extends in front of the lens of the light guide 3b from the front side of the main body portion 3a, a plane parallel to the lateral direction of the spectacle second planar S ₂ To do. In addition, the center line is a line that connects the positions of the centers (the center of gravity of the cross-sectional shape) of each cross section perpendicular to the longitudinal direction at each position in the longitudinal direction (extending direction) of the housing. Plane S ₂ of the second becomes the surface on which the front is inclined obliquely downward when viewed from the wearer in perpendicular to the plane of FIG. 1 (a). The second plane is inclined 5 to 20 degrees with respect to the first plane.

Furthermore, in a state where the eyeglass 10 is attached, the first plane S ₁ and the second plane S ₂ intersect at a point P ₂ on the eyeball side of the lens 10 c of the eyeglass 10. By doing so, the first portion 4a has a height that substantially matches the height of the temple of the glasses, and is easy to fix to the temple, while the portion that connects the rim portion 10e of the glasses and the armor 10d, Since the housing | casing 3 passes under those, interference with the spectacles 10 and the housing | casing 3 can be avoided.

Further, the dimensions of the first portion 4a of the housing 3, than in the direction perpendicular to the first plane S ₁ thin in a direction parallel to the first plane S _1, the housing 3 of the light guide dimensions of parts 3b are thin vertical direction than a direction parallel to the second plane S _2. The first portion 4a at the rear of the housing 3 is thinned to make it inconspicuous with little lateral protrusion, while the light guide 3b at the front of the housing 3 is thinned in the vertical direction so that the wearer It is possible to avoid obstructing as much as possible.

In particular, the thickness d of the second direction perpendicular to the plane S ₂ of the portion image light emitting portion 5 of the light guide section 4b is provided is thinner than 4mm is an average pupil diameter size of human . A see-through effect can be obtained by making the image emitting portion 5 thinner than the pupil diameter of a human. That is, the wearer of the glasses-mounted display device 1 can observe an image obtained by superimposing the display image on the display panel 7 and the background visual field.

Further, the dimension in the direction perpendicular second to the plane S ₂ of the second portion 4b of the housing 3, than the dimension in the direction perpendicular the first to the plane S ₁ of the first portion 4a small. By doing so, the size in a direction perpendicular second to the plane S ₂ of the second portion 4b, or equal to the dimension in the direction perpendicular to the first plane S ₁ of the first portion 4a Compared with the case of more than that, interference with the rim | limb part 10e of the spectacles 10 and the armor 10d can be prevented, and the blind spot produced by the housing | casing 3 within a wearer's visual field can be decreased.

  2 is a diagram showing the positional relationship between the eyeglass-mounted display device of FIG. 1 and the eyeball when the wearer is worn on the head, and FIG. 2A is a side view seen from the eyeball 11 side. FIG. 2B is a top view.

As shown in FIG. 2 (a), the second plane _{S 2} is in a state of being attached to the spectacles 10, passes through the center 11a of the wearer's eye 11. Therefore, the optical axis of the eyepiece optical part built in the light guide part 3b can be made to coincide with the wearer's approximate eyeball center 11a. As a result, the apparatus can be miniaturized and a display image can be displayed at a position that is most easily seen by the wearer.

A suitable inclination angle of the second portion 4b with respect to the first portion 4a can be determined as follows. First, the inclination of the spectacle lens is generally about 5 to 10 degrees, and the inclination angle can be adjusted to the angle. Further, it is said that the line-of-sight position of the personal computer monitor screen recommended in VDT work or the like is about 10 to 15 degrees below, and it is possible to provide an image display that is less fatigued by matching the position. In addition, when priority is given to applications that do not continue to be seen and external field of view, for example, when it is always worn and used and occasional confirmation of incoming mails in a short time, about 15 to 20 degrees is preferable. In any case, since it is inclined downward with respect to the horizontal direction, it is possible to provide a display image that is easy to see and use. In other words, by first plane S ₁ and the angle between the second plane S ₂ and 5-20 degrees, it is possible to provide an easy display images using visible.

  FIG. 3 is a diagram showing the electric board built in the casing of the main body and the eyepiece optical unit from the main body to the image emitting unit together with the position of the eyeball. FIG. 3 (a) is a side view and FIG. b) is a top view.

  As shown in FIGS. 3A and 3B, the housing 3 includes an electric substrate 6, a display panel 7, a first light guide member 21, a second light guide member 22, and an eyepiece lens 23. The eyepiece optical part 20 including it is incorporated. The electric board 6 and the display panel 7 are disposed inside the main body 3 a of the housing 3 and are connected via a connector 8 and a flexible cable 9.

  The electric board 6 is connected to an external computer device by wireless or wired, receives data for image display, and outputs an image signal of a display image to be displayed to the display panel 7 via the connector 8 and the flexible cable 9. To do. The electric board 6 extends from the first portion 4a to the second portion 4b of the main body 3a, and has a bent shape corresponding to the bending between the first portion 4a and the second portion 4b. Thereby, effects such as downsizing and improvement in assemblability can be obtained.

The display panel 7 has a rectangular shape, and is disposed along the surface of the electric substrate 6 in the second portion 4 b and in the vicinity of the tip of the electric substrate 6. Each side of the display panel 7 is inclined with respect to the first plane S ₁ corresponding to the bending of the electric substrate 6. On the other hand, the display panel 7 is vertically and for the second plane S _2, two parallel sides of the four sides forming the rectangular shape is in the direction along the second plane S _2.

  On the other hand, the first light guide member 21, the second light guide member 22, and the eyepiece lens 23 constituting the eyepiece optical unit extend from the main body 3a located in the second portion into the light guide 3b. . That is, the eyepiece optical unit is held by the second part.

The first light guide member 21 is made of a resin material or glass material having high light transmittance, and is a first surface 21a, a second surface 21b, a third surface 21c, and a fourth surface that are perpendicular to the _second plane S2. 21d and a hexahedron prism having six faces of the second fifth face 21e parallel to the second plane _{S 2} across the plane _{S 2} equidistant and sixth surface 21f. The first surface 21a and the second surface 21b are substantially parallel surfaces. The second surface 21 b is a surface along the display panel 7, is adjacent to the display panel 7, and has an incident portion 21 g on which image light of a display image of the display panel 7 is incident. The third surface 21c is a reflective surface located rearward between the first surface 21a and the second surface 21b, and forms an acute angle with the second surface 21b. The fourth surface 21d is a surface positioned forward between the first surface 21a and the second surface 21b.

The second light guide member 22 is made of a resin material or glass material having a high light transmittance, and the first surface 22a, the second surface 22b, the third surface 22c, and the fourth surface perpendicular to the _second plane S2. 22d and, with the fifth surface 22e and the sixth surface 22f forming a tapered shape 22d side is narrower than the parallel or 22c side of the second plane _{S 2} to the second plane _{S 2} across equidistant This is a rod-shaped hexahedral prism having six surfaces. The first surface 22a is a plane that faces the fourth surface 21d of the first light guide member 21 and is substantially parallel to the fourth surface 21d. The second surface 22b is a reflecting surface parallel to the first surface 22a located in front of the first surface 22a. The third surface 22c and the fourth surface 22d are reflective surfaces provided between the first surface 22a and the second surface 22b and on the main body 3a side and the eyepiece lens 23 side, respectively. An acute angle is formed with the surface 22a. Further, the first surface 22a is incident on an incident portion 22g facing and adjacent to the fourth surface 21d of the first light guide member 21, and an eyepiece 23 described later disposed at the distal end portion of the light guide portion 3b. It has the output part 22h which opposes the surface 23a.

  The eyepiece lens 23 is a lens having a positive refractive power, and has an incident surface 23 a that is a plane facing the emitting portion 22 h of the second light guide member 22 and an emitting surface 23 b that is a convex surface. The image light emitting unit 5 is composed of an eyepiece lens 23. Note that an air gap is formed between the emission portion 22 h of the second light guide member 22 and the incident surface 23 of the eyepiece 23.

In addition, between the fifth surface 21e and the sixth surface 21f of the first light guide member 21 and between the fifth surface 22e and the sixth surface 22f of the second light guide member 22, the upper and lower sides of the display panel 7 are arranged. They are separated by a distance equal to or slightly wider than the direction width. Furthermore, the fifth surface 22e and the sixth surface 22f are made narrower toward the eyepiece lens 23, so that the vertical width of the light guide member 22 near the eyepiece lens is made smaller than the vertical width of the display panel 7. Can do. Similarly, the vertical width of the eyepiece lens 23 can be made smaller than the vertical width of the display panel 7. Moreover, these first light guide member 21, the optical axis path of the second light guide member 22 and the eyepiece 23 is configured to conform to the second plane S _2.

  With the configuration of the eyepiece optical unit 20 as described above, the image light of the display image on the display panel 7 enters the first light guide unit 21 from the incident unit 21 g of the first light guide member 21. The image light incident on the first light guide member 21 is reflected forward by the third surface 21c and emitted from the fourth surface 21d.

  The image light emitted from the fourth surface 21d of the first light guide member 21 passes from the incident portion 23g located on the main body 3a side of the first surface 22a to the second light guide member 22 via the air gap 24. Incident. The image light incident from the incident portion 23g is reflected by the third surface 22c in a direction having an inclination with respect to the first surface 22a and the second surface 22b. Accordingly, the image light reflected by the third surface 22c is sequentially reflected in the second light guide member in the order of the first surface 22a, the second surface 22b, and the first surface 22a, and is positioned at the tip of the light guide unit 3b. The light is guided to the vicinity of the image light emitting unit 5 that performs the operation. Thereafter, the image light is reflected by the fourth surface 22d and emitted from the emission portion 22h of the first surface 22a. Thus, by setting it as the structure reflected inside the 2nd light guide member 22 5 times, the depth to the front of the 2nd light guide member 22 can be made small.

  The image light emitted from the emission part 22h of the second light guide member 22 is incident on the incident surface 23a of the eyepiece lens 23 via the air gap 25, refracted by the emission surface 23b, and emitted toward the eyeball center 11a. Is done. Note that the air gap between the exit portion 22h of the light guide member 22 and the entrance surface 23a of the eyepiece 23 is such that part of the image light reflected by the second surface 22b before the entrance surface 23a is the first. The direct incidence to the eyepiece lens 23 is suppressed without being reflected by the first surface 22a.

As described above, the image light from the display panel 7, is only reflected by the plane perpendicular to the second plane S ₂ in the eyepiece optical unit 20 in the light guide portion 3b, the optical axis path of the second plane S ₂ It enters the eyeball 11 of the wearer along the top. For this reason, the display image of the display panel 7 is observed as an image without inclination. Thus, by tilting the display panel 7 according to the tilted second portion 4b and the eyepiece optical unit 20 in the light guide portion 3b, the display screen does not appear to tilt in the wearer's field of view. It becomes easy to provide an easy-to-view image in an appropriate orientation.

  In addition, since the second plane and the plane formed by the optical axis path of the eyepiece optical unit coincide with each other, the display image is displayed at an easily viewable position in the wearer's visual field.

  Furthermore, the eyepiece lens 23 side and the eyepiece lens 23 of the light guide member 22 are smaller than the vertical width of the display panel 7, and the vertical width is smaller than 4 mm, which is an average human pupil diameter. See-through effect is obtained.

  The display panel 7 can be arranged on the front side of the electric substrate 6 with the surface of the display panel 7 perpendicular to the surface of the electric substrate 6, that is, with the display panel 7 facing diagonally forward and downward. . In the present embodiment, the thickness of the main body 3a is further reduced by arranging the electric circuit board 6 along the electric board 6.

  In addition, the display panel 7 can be arranged on either the left or right side with respect to the electric substrate 6. That is, as shown in FIG. 3B, a left-eye connector 8 ′ is provided on the surface opposite to the connector 8 on the electric board 6, and the left-eye glasses-mounted display device. Then, the flexible cable 9 ′ and the display panel 7 ′ are attached thereto. In this manner, the same substrate can be applied to the right and left eyeglass-mounted display devices, and the cost can be reduced.

  With the configuration as described above, the first portion 4a (the rear side of the main body 3a) of the housing 3 is fixed to the temple 10a of the glasses 10 by two fixing portions. Further, since the second portion 4b of the housing 3 is inclined downward, the display image displayed on the display panel 7 by the image signal of the electric board 6 is transmitted through the light guide 3b to the eyeball 11. Incident from below. As a result, the display image is displayed 5 to 20 degrees below the horizontal line of sight in the wearer's field of view.

  As described above, according to the present embodiment, when the spectacles-mounted display device is viewed in the horizontal direction, the second portion is inclined downward with respect to the first portion, so that the wearer The display image can be presented at a position where it is easy to see.

  In the glasses-mounted display device, the first portion of the rod-shaped main body is supported at two points in parallel to the glasses temple, so that it can be stably and firmly fixed to the glasses.

  Further, the glasses-mounted display device is configured such that the bending point between the upper surface portion of the first portion and the upper surface portion of the second portion is closer to the ear side than the hinge portion of the glasses, and the second portion is The eyeglass armor is placed at a position where it can be seen above, and the intersection of the first plane and the second plane is configured to be a point on the eyeball side of the eyeglass lens. On the other hand, it is possible to avoid the interference with the eyeglass armor or rim.

  In addition, since the second plane passes through the center of the eyeball of the wearer, the two parallel sides of the display panel are along the second plane, and the optical axis path of the eyepiece optical unit coincides with the second plane. The image on the display panel is displayed as an easy-to-see image with no inclination in the field of view of the wearer.

  Furthermore, since the eyepiece optical part of the second part is configured by using a small light guide member made of a resin material or glass material having a high light transmittance, the second part can be stably supported. And the whole apparatus can be comprised small and lightweight.

  In addition, this invention is not limited only to the said embodiment, Many deformation | transformation or a change is possible. For example, in the above embodiment, the right-eye glasses-mounted display device has been described. However, the left-eye glasses-mounted display device can be configured similarly.
