Description

  The present invention relates to a head mounted display.

  In recent years, a head-mounted display that is worn on the head of a human body and allows the wearer to visually recognize an image, and a wearable computer using the head-mounted display have been developed. If the head-mounted display is connected to a mobile computer, a computer graphic screen is formed as a virtual image in front of the user's eyes, thus providing a wearable computer that can be mounted on the user's head.

As a specific form of the head mounted display, as described in Patent Documents 1 and 2, there is a head mounted display that projects an image on at least one eye.
Patent Documents 1 and 2 describe a head-mounted display that can be switched between a right-eye display form that projects an image to the right eye and a left-eye display form that projects an image to the left eye.
Patent Documents 1 and 2 describe an image display unit that is supported by a hair band-shaped or ring-shaped head-mounted device.
In the invention described in Patent Document 1, the image display unit can be converted into a right-eye display form and a left-eye display form by inverting the image display unit vertically and horizontally and inverting the whole.
In the invention described in Patent Document 2, the right-eye display mode is achieved by holding the image display unit so as to be movable between the right eye and the left eye without re-mounting the head-mounted device. And the left-eye display form.

A head-mounted display is mounted on the head and projects an image on the eye, but a person with a bad eye sees the image through a glasses lens.
On the other hand, those who do not need glasses or those who use contact lenses do not need glasses lenses, but if there is an accident that hits the face with the head mounted display, the display member sticks into the eyes Because it is dangerous, a protective lens (eye shield) is required.
In order to allow one head-mounted display to be used by both of the above, a lens unit is disclosed that can be replaced with one that has a degree and one that has no degree (Patent Document 3).

  An embodiment of the present invention will be described below with reference to the drawings. The following is one embodiment of the present invention and does not limit the present invention.

In the figure, three orthogonal axes XYZ are shown. The X-axis indicates the left-right direction, the Y-axis indicates the front-rear direction, and the Z-axis indicates the up-down direction.
The detailed description of the head mounted display 1A (main body) will be described later, and the description centered on the attachment will be described first.
[Description of attachment]
Hereinafter, Embodiments 1 and 2 of the attachment units B10 and C10 provided with both the guard member and the nose pad will be described in order. The third embodiment is a case where no attachment is used.

[Embodiment 1]
As shown in FIG. 1, an attachment unit B10 according to Embodiment 1 of the present invention is attached to a main frame 10 of a head mounted display 1A including an image display unit a.
The attachment unit B10 is integrally provided with a guard member B101 and a nose pad B201.
As shown in FIG. 2, the attachment unit B10 includes a pair of clips B102 and B103 having elastic claws, and is attached by being inserted from the rear of the main frame 10 as shown in FIGS. At this time, the pair of clips B102 and B103 are arranged so as to sandwich the image display unit a.
As shown in FIG. 4 and the like, the guard member B101 is entirely disposed in a region around the display portion a11 when viewed from the wearer. This is to prevent the guard member B101 from overlapping the image displayed on the display unit a11 when viewed from the wearer. Therefore, the guard member B101 does not have a member in the display portion a11, that is, a region overlapping the display image as viewed from the wearer like a spectacle lens or an eye shield, and does not have a member in the same region. Therefore, the guard member B101 does not need to be transparent.
In the case of the present embodiment, the guard member B101 is formed in a curved rod shape, and both ends are connected to and supported by the pair of clips B102 and B103.

  As shown in FIG. 5, in the guard member B101, the lower end B104 extending in the left-right direction is disposed between the display member a10 and the wearer's face to receive the display member a10 and the display member a10 hits the wearer's eyes. It is mounted so as to prevent it. As a result, it is safe without wearing glasses or non-special glasses (protective glasses), and those who do not wear glasses do not need to wear glasses, so there is little burden, and those who wear glasses can also attach the attachment unit B10. Since the eye can be comfortably worn by removing the eyeglasses and the eye is protected, it is possible to wear safely and with little burden regardless of whether or not diopter correction is performed.

  The lower end B104 of the guard member B101 is disposed on the opposite side of the support end B105 of the image display unit a via the display unit a11. In the case of the present embodiment, the display member a10 is supported by the main frame 10 at the upper end and protrudes substantially downward, and the lower end B104 of the guard member B101 is disposed so as to contact the lower end of the display member a10. When the head mounted display 1A receives an impact, the tip of the display member a10 projecting from the main frame 10 is likely to be displaced to the wearer's face side and may come into contact with the face, which is a guard member B101. This is to catch it. In the case of the present embodiment, the guard member B101 is particularly effective because the image display unit a has a mechanism that rotates about the X axis in the left-right direction. In addition, even when the display member a10 is fixed without such a rotation mechanism, the tip of the display member a10 may be displaced toward the face of the wearer due to deformation, partial breakage, or the like. The guard member B101 of this embodiment is effective.

As shown in FIG. 6, the attachment unit B10 includes a guard member B101, a pair of clips B102 and B103, two shafts B106 and B107, a coil spring B108, a nose pad B201, a slider B202, and a turn base B203. And is assembled as shown in FIGS.
Both end portions B110 and B116 of the guard member B101 are coupled to the rear end portions of the clips B102 and B103 so as to rotate around the X axis via the shafts B106 and B107, respectively. As a result, the guard member B101 is disposed at the center in the vertical direction of the main frame 10 and rotates about the left and right axis when mounted on the main frame 10 as represented in FIGS. Thus, they can be arranged at positions that are opposite to each other. Thereby, as shown in FIGS. 52A, 52B, 53A, and 53B, the right-eye display form and the left-eye display form that are mutually switched by rotating the head mounted display 1A about the Y axis by 180 degrees. The guard member B101 can be used.
The end B110 connected to the rear end B109 of the clip B102 of the guard member B101 as shown in FIG. 12A is sandwiched and restrained in the X-axis direction, and as shown in FIG. It is stably held at a predetermined rotation angle. By setting the angle corresponding to the right-eye display form and the angle corresponding to the left-eye display form as the predetermined rotation angle that is stably maintained, it is easy to switch between the two forms, and the usability Will improve.

  The nose pad B201 is fixed to the slider B202, and the slider B202 is slidably connected to the turn base B203. The nose pad B201, together with the slider B202, is moved to the left and right as shown in FIGS. Can be moved to. That is, the nose pad B201 is held so as to be movable in the left-right direction with respect to the main frame 10. Thus, the position of the display unit a11 can be adjusted to an appropriate position with respect to the wearer's eyes with reference to the wearer's nose.

As shown in FIGS. 6 and 15, a spherical cam B112 is formed at the rear end of the clip B103. In the spherical cam B112, similarly to the above-described clip B102 side, a rod through groove B113 that sandwiches the end B116 of the guard member B101 is formed in the Z-axis direction. A cam groove B114 is formed in the spherical surface portion adjacent to the rod through groove B113 of the spherical cam B112. The spherical concave portion B115 of the turn base B203 is urged by the coil spring B108 and pressed against the spherical cam B112, and at least one of the two convex portions B117 and B118 provided on the turn base B203 is always fitted in the cam groove B114. The nose pad B201 is connected and held at a fixed mounting angle with respect to the turn base B203. As a result, a mechanical mechanism that links the rotation of the nose pad B201 relative to the guard member B101 with the rotation of the guard member B101 relative to the main frame 10 is configured, and is expressed in FIG. 9, FIG. 10, and FIG. In conjunction with the rotation of the guard member B101 about the X axis, the nose pad B201 rotates 180 ° about the longitudinal axis of the end portion B116, so that the nose pad B201 is moved upward or downward. Is always placed on the face side of the wearer. Therefore, the nose pad B201 is configured to be able to rotate with respect to the guard member B101 and be disposed at positions opposite to each other.
As described above, as shown in FIGS. 52A, 52B, 53A, and 53B, the right-eye display form and the left-eye display form that are mutually converted by rotating the head mounted display 1A by 180 ° around the Y axis. The guard member B101 and the nose pad B201 can be used.

The principle of the mechanical mechanism that realizes the interlocking rotation of the guard member B101 and the nose pad B201 will be described with reference to the schematic diagrams of FIGS.
As shown in FIG. 16, the cam groove B114 is divided into upper and lower parts by a rod through groove B113. An escape groove B119 is formed on the spherical surface opposite to the cam groove B114 via the rod through groove B113. The escape groove B119 is a portion formed so as not to interfere with the convex portions B117 and B118, and its shape is arbitrary. The convex portions B117 and B118 are guided by the cam groove B114.
Since the end B116 of the guard member B101 is inserted into the hole B204 formed in the turn base B203 and pivots up and down, the hole B204 also moves up and down.
FIG. 17 shows the movement locus of the turn base B203 in this mechanism. 18A to 18I show the movement locus of the turn base B203 with respect to the spherical cam B112.
In FIG. 18A to FIG. 18E, one of the convex portions B118 is guided by the lower cam groove B114, so that the turn base B203 rotates 90 ° around the axis passing through the center of the hole B204 and the center of the spherical cam B112. .
In FIG. 18E, the other convex portion B117 jumps into the upper cam groove B114.
In FIGS. 18E to 18I, the turn base B <b> 203 is further rotated by 90 ° around the axis passing through the center of the hole B <b> 204 and the center of the spherical cam B <b> 112 by guiding the other convex portion B <b> 117 to the upper cam groove B <b> 114. .
As described above, the interlocking rotation of the guard member B101 and the nose pad B201 is realized.

[Embodiment 2]

In the present embodiment, the attachment pins C104 and C105 are press-fitted and attached to the attachment holes C106 and C107 or the attachment holes C108 and C109 provided on the head mounted display 1A side. As a result, the guard member C101 is configured to be able to be selectively mounted on the main frame 10 at positions upside down by being inverted about the X axis. The press-fitting of the pin into the hole is an example, and the detachable structure is arbitrary.
The nose pad C201 is connected to the guard member C101 so as to be rotatable about the Z axis, and as shown in FIGS. 22 and 23, the nose pad C201 is in a position reverse to the front and rear with respect to the guard member C101. It is configured to be able to be arranged in.
As described above, as shown in FIGS. 52A, 52B, 53A, and 53B, the right-eye display form and the left-eye display form that are mutually converted by rotating the head mounted display 1A by 180 ° around the Y axis. The guard member C101 and the nose pad C201 can be used. 20 and 21 show the right-eye display in this embodiment. As shown in FIG. 22, the guard member C101 is inverted around the X axis, and from the state shown in FIG. 22, the nose pad C201 is inverted around the Z axis as shown in FIG. 23, and from the state shown in FIG.

The image display unit a has a display member a10 disposed in front of the eye of the wearer H and an image generation unit (not shown) for generating an image displayed on the display member a10 fixed to the housing a20. The base end portion of the display member a10 and the image generation unit are accommodated in a20.
The display unit a11 is configured such that an image is observed on one side surface (rear side surface) of a portion of the display member a10 that protrudes from the housing a20.
The image display unit a guides the image light generated by the image generation unit including a light source, a liquid crystal display element, and the like in the housing a20 to the pupil of the wearer H via the display member a10. The image light generated by the image generation unit travels while being reflected in the display member a10, and is incident on the hologram element a13 disposed in an inclined manner in the display member a10. The hologram element a13 is provided so as to diffract only light of specific wavelengths (three wavelengths corresponding to RGB) and direct it toward the pupil of the wearer H. Thus, the display member a10 constitutes a see-through display member that can transmit light from the outside and enter the pupil of the wearer H. The wearer H can visually observe a real observation image of the outside world and a display image (virtual image) by image light that is superimposed on a part of the real observation image and guided through the display member a10. Even in this range, the actual observation image can be viewed through the display member a10.
The head mounted display 1A of the present embodiment is a single-eye display type, but a binocular display type may be implemented.

As shown in FIGS. 30, 31, and 32, the head mounted display 1 </ b> A is supported by the glasses 100 worn by the wearer H while the pair of HMD temples 20 and 20 are hung on the ear of the wearer H. A fulcrum is provided and attached. The fulcrum is constituted by a pair of support portions 30 and 30.
That is, each of the pair of support portions 30 and 30 constitutes a fulcrum in contact with the temple 101 of the glasses 100 in front of the ear H1 of the wearer H. The support portion 30 of the present embodiment is in contact with the upper end of the temple 101, that is, is placed on the temple 101.
Such a pair of support portions 30, 30 are connected to the pair of HMD temples 20, 20. Specifically, the support portion 30 is connected to the rear portion 22 of the HMD temple 20.
The front part 21 of the HMD temple 20 is connected to the front part 21 of the support part 30 and the rear part 22 via a shaft hinge 21a so as to be rotatable up and down with respect to the rear part 22. The axial direction of the shaft hinge 21a is the X-axis direction.

The front end of each HMD temple 20 is connected to the main frame 10 by a shaft hinge 21b. The axial direction of the shaft hinge 21b is the Z direction, and a pair of HMD temples 20 and 20 can be opened and closed like a typical eyeglass frame.
The shaft hinge 21b is movably held in the guide hole 10a. The shaft hinge 21b is moved along the guide hole 10a so that the front ends of the pair of HMD temples 20 and 20 can be moved closer to or away from each other. That is, the pair of HMD temples 20 and 20 are arranged relatively close to each other so as to correspond to a relatively small head size, or paired so as to correspond to a relatively large head size. The HMD temples 20 and 20 can be arranged relatively far from each other in a substantially parallel state, and can be appropriately adjusted between these states. When the head size is relatively small, the entire pair of HMD temples 20 and 20 is slightly forward. When the head size is relatively large, the entire pair of HMD temples 20 and 20 is The guide hole 10a is formed obliquely so as to be disposed slightly rearward.
It is preferable to form serrations on the inner edge of the guide hole 10a so that the shaft hinge 21b can be moved stepwise at a predetermined pitch and held at each position. Further, in order to allow the position adjustment of the shaft hinge 21b, the forming member of the guide hole 10a is given appropriate elasticity. Accordingly, the shaft hinge 21b can be held so as not to move during use, and the position can be adjusted by applying a force in the extending direction of the guide hole 10a.

Next, a support structure for the image display unit a will be described.
As shown in FIG. 33A, a housing a20 of the image display unit a is attached to the main frame 10. It is a display form in this state.
The main frame 10 includes a display portion right extending portion 11R that extends to the right on the right side of the image display unit a in the display mode, and a display portion that extends to the left on the left side of the image display unit a in the display mode. 11L.
Specifically, the left end of the display portion right extending portion 11R is disposed at a position adjacent to the right side surface of the housing a20 and extends rightward therefrom. The right end of the display portion left extending portion 11L is disposed at a position adjacent to the left side surface of the housing a20 and extends leftward therefrom. Since the display unit a11 is arranged in front of the right eye of the wearer H and the image display unit a is unevenly arranged on the right side in the present embodiment, the display unit left extending unit 11L is long. On the other hand, the display portion right extending portion 11R is formed short. The display portion left extending portion 11L includes a central portion of the main frame 10 facing the wearer's eyebrows.

The rear surface of the image display unit a is arranged behind the display portion right extending portion 11R and the display portion left extending portion 11L. Specifically, the rear surface a21 of the housing a20 is disposed behind the rear surface 11R1 of the display unit right extension 11R and the rear surface 11L1 of the display unit left extension 11L.
As shown in FIG. 33B, the main frame 10 has a left end portion 11R of the display portion right extension portion 11R.
2 and the bridge portion 12 that connects the right end portion 11L2 of the display portion left extending portion 11L.
The bridge portion 12 is provided so as to extend from side to side through the rear side of the rear surface a21 of the image display unit a.
The bridge portion 12 includes a bridge main portion 12M, a right leg portion 12R, and a left leg portion 12L. The bridge main part 12M is a part across the range in which the image display unit a in the display mode is arranged with respect to the X coordinate, and extends long in the left-right direction.
Since the bridge main part 12M passes right and left through the rear side of the rear surface a21, a drop in the front-rear direction occurs between the display part right extension part 11R and the display part left extension part 11L. The right leg portion 12R and the left leg portion 12L are portions that fill the gap. That is, the right leg portion 12R is continuous with the right end portion of the bridge main portion 12M, extends forward, and is connected to the left end portion 11R2 of the display portion right extension portion 11R. The left leg portion 12L is continuous with the left end portion of the bridge main portion 12M, extends forward, and is connected to the right end portion 11L2 of the display portion left extension portion 11L.

A heat conductive material is applied to the display portion right extending portion 11R and the display portion left extending portion 11L, and the heat conductive material is thermally connected so as to absorb heat generated in the image display unit a in the display mode. . The heat generated in the image display unit a is released to the display portion right extending portion 11R and the display portion left extending portion 11L to radiate heat. For this thermal connection, the right leg portion 12R, the left leg portion 12L, the right latch portion 16R, the left latch portion 16L, and the contact portion with at least the left and right side main frame 10 of the housing a20 are also thermally conductive. Material is applied. Further, the heat generating part due to the power consumption in the housing a20 is thermally connected to the contact portion of the housing a20 with the main frame 10.
As shown in FIG. 33A, a gap 12A is provided between the rear surface a21 of the image display unit a and the bridge main portion 12M. The air gap 12A functions as a heat insulating layer for preventing heat conduction to the wearer side. Therefore, the space 12A may be filled with a heat insulating material.
Further, a cover 13 made of a heat insulating material that covers the rear surface 12 </ b> M <b> 1 facing the face of the wearer of the bridge portion 12 is attached to the bridge portion 12. This is to prevent the bridge main part 12M from directly contacting the wearer's face and to suppress heat transmitted to the wearer.
As the above heat conductive material, it is preferable to apply a material having a heat conductivity of 5 to 300 (W / m · K). Examples of materials include aluminum (thermal conductivity 250 (W / m · K)), magnesium (thermal conductivity 156 (W / m · K)), thermal conductive resin (thermal conductivity 7 (W / m · K)). ).
As the above heat insulating material, it is preferable to apply a material having a thermal conductivity of 0 to 0.3 (W / m · K). Examples of materials include silicone rubber (thermal conductivity 0.2 (W / m · K)) and polycarbonate (thermal conductivity 0.19 (W / m · K)). The thermal conductivity of air is 0.024 (W / m · K).

As shown in FIGS. 34 to 37, the image display unit a in the display mode is supported via the first hinge about the front-rear direction axis Y, and is attached to the main frame 10 via the second hinge 14b about the vertical direction axis. A connected arm 14 is provided.
The display unit right front protrusion 15R and the display unit left front protrusion 15L are portions that protrude forward from the display unit right extension 11R and the display unit left extension 11L on the left and right of the housing storage unit 10c. And provided continuously to the left leg 12L.
The arm 14 has substantially the same length as the bridge main portion 12M and is hung on the front side opposite to the bridge main portion 12M. The arm 14 and the display portion left front protrusion 15L are formed by the bridge portion 12, the display portion right front protrusion 15R. 30 and FIG. 31, the casing a20 is surrounded, and the casing storage section 10c shown in FIG. 34 is defined. In the display mode, the casing a20 is stored and fixedly held in the casing storage unit 10c.
The second hinge 14b is provided so as to connect the arm 14 and the display unit front left projection 15L. The right end of the arm 14 is captured by the display unit front right projection 15R in the state of FIG. Note that a lock mechanism that captures and holds the arm 14 at the right front protrusion 15R of the display unit is configured, and a lock release operation is also possible.
A shaft portion 14 a of the first hinge is formed so as to protrude rearward inside the center portion of the span of the arm 14. On the other hand, as shown in FIG. 35, a hole a22 of the first hinge is formed on the front surface of the housing a20. As shown in FIGS. 36 and 37, the shaft portion 14a is fitted into the hole a22 to form a first hinge, and the image display unit a in the display mode is connected to the image display unit a via the first hinge about the front-rear direction axis Y. To support.

As described above, the first hinge (14a, a22) is arranged at the center of the horizontal dimension of the image display unit a, and the second hinge 14b is arranged on one side of the image display unit a.
As shown in FIG. 30, FIG. 31, etc., in the display mode, the image display unit a is held by the main frame 10 so that the image display unit a cannot be reversed vertically by the first hinge. In particular, the latch portions 16L and 16R are provided on the left and right inner portions of the housing storage portion 10c in order to hold them without rattling. The latch part 16L and the latch part 16R are left-right symmetric and have long grooves in the front-rear direction. The fixing blade a23 (see FIGS. 38B, 39A, and 39B) formed on the left and right sides of the housing a20 is caught in the groove, and the image display unit a is fixed to the main frame 10.

As can be seen from the process of FIG. 38A → FIG. 38B → FIG. 39A → FIG. 39B → FIG. 40 or vice versa, the first display unit a can be removed by rotating around the second hinge 14b to the front. The image display unit a can be flipped vertically and horizontally by the hinges (14a, a22).
As shown in FIG. 39A and FIG. 39B, the image display unit a is rotated about 90 degrees around the second hinge 14b and detached forward, and then the first hinges (14a, a22) arranged substantially in the left-right direction. Rotate around and flip up, down, left and right. At that time, as shown in FIG. 39A, the image display unit a is rotated using the space of the housing storage portion 10c.

As shown in FIG. 37 and the like, the head mounted display 1A has the cable 40 extending from the housing a20 of the image display unit a passed through the vicinity of the first hinge (14a, a22) and further pulled out through the vicinity of the second hinge 14b. It is supposed to be configured. Accordingly, the operation of the process of FIG. 38A → FIG. 38B → FIG. 39A → FIG. 39B → FIG. 40 and the reverse process can be smoothly performed, and the gable 40 can be routed with almost no margin length, and the load on the gable 40 Is also suppressed.
Furthermore, in order to suppress the load on the gable 40, the image display unit a is prevented from rotating beyond 180 degrees. That is, the rotation by the first hinge (14a, a22) is restricted so as to be limited to a range in which the up / down / left / right reversal operation of the image display unit a is possible. The specific regulatory structure is as follows. As shown in FIG. 34, a cable holder 14c is formed between the shaft portion 14a of the first hinge on the inner surface of the arm 14 and the second hinge 14b. The cable 40 routed from the vicinity of the first hinge (14a, a22) to the vicinity of the second hinge 14b is fitted into the cable holder 14c and held. This is a restriction structure in which the lower surface of the front portion of the housing a20 comes into contact with the cable holder 14c and stops.
As a result, the load applied to the gable 40 is suppressed, deterioration of the conductive wire of the gable 40, disconnection, and the like are prevented, and good quality retention that can be used for a long time is achieved.

As shown in FIGS. 30 and 31, the cable 40 is configured to be drawn out to the side (left side) opposite to the side (right side in FIGS. 30 and 31) where the image display unit a of the head-mounted device is unevenly distributed. . Thereby, since the cable 40 passes the center part of the main frame 10 which opposes a wearer's eyebrows, the weight balance of the right and left of this head mounted display is favorable.
The display portion left extending portion 11L has a hollow structure in which a hollow portion penetrating in the longitudinal direction is formed, and the cable 40 is passed through the hollow portion.
Since the cable 40 does not extend up and down, front and rear, etc. of the main frame 10, when the head mounted display is worn or when the helmet or hat is worn together, the head mounted display is worn or the helmet or hat is worn. There is no hindrance. Further, since the cable 40 passes through the main frame 10, it is protected from external pressure and the like, and it is not exposed and does not impair the beauty.

Next, the structure of a single unit of the support part 30 and the connection structure to the HMD temple 20 will be described (refer to FIGS. 41 to 47 as appropriate).
A perspective view of the support portion 30 is shown in FIG. 41, and an exploded perspective view is shown in FIGS. The support portion 30 is composed of three components, a connection frame 31, a left / right rotation frame 32, and a rubber pad 33.
Since the rubber pad 33 is a part in contact with the temple 101 of the glasses 100 (see FIG. 32), the rubber pad 33 is made of a non-slip rubber material.
The left and right rotating frame 32 is fitted inside the rubber pad 33, and the rubber pad 33 is integrally fixed to the left and right rotating frame 32. The left and right rotating frame 32 and the rubber pad 33 are formed with a retaining shape for fixing them to each other, and the left and right rotating frame 32 is fitted inside the rubber pad 33 with the elastic deformation of the rubber pad 33.
A left and right rotation shaft portion 31 a is protruded from the rear end portion of the connection frame 31, and a bearing female portion 32 a that fits into the left and right rotation frame 32 is drilled. The left / right rotation shaft portion 31a is fitted into the bearing female portion 32a, and the left / right rotation frame 32 is held by the connecting frame 31 so as to be rotatable left and right. The left-right rotation shaft portion 31a and the bearing female portion 32a are formed with a retaining shape for fixing them to each other, and the left-right rotation shaft portion 31a is split so as to be easily elastically deformed. With the elastic deformation of the moving shaft portion 31a, the left and right rotating shaft portion 31a is fitted into the bearing female portion 32a.
After the fitting, the inner surface of the bearing female portion 32a is pressed by the elastic recovery force of the left and right rotation shaft portion 31a. Thereby, the left-right rotation frame 32 and the connection frame 31 are fitted and connected by an elastic friction fit.

A substantially sector-shaped rotation restricting hole 32b is formed in front of the bearing female portion 32a of the left and right rotating frame 32, and a rotation restricting protrusion is formed in front of the left and right rotating shaft portion 31a of the connecting frame 31. A portion 31c is formed. The front end portion of the rotation restricting convex portion 31c constitutes a front holding projection 31c1 protruding forward.
When the left and right rotation shaft portion 31a is fitted into the bearing female portion 32a, first, the front holding projection 31c1 is inserted into the rotation restriction hole 32b and disposed on the rubber pad 33 mounting side, and the left and right rotation shaft portion 31a is disposed. Push into the bearing female portion 32a.
As shown in FIGS. 44A and 44B, the left and right rotation frame 32 (the rubber pad 33 fixed integrally with the left and right rotation frame) is rotated left and right by the rotation restriction convex portion 31c coming into contact with the inner edge of the rotation restriction hole 32b. To regulate. For example, it is set to ± 5 °.

A connection housing 31b is formed on the opposite side of the left and right rotation shaft portion 31a at the rear end portion of the connection frame 31. The connection housing 31b has a structure in which front and rear surfaces are open and members are provided on the left and right side surfaces and the upper surface. Pivot projections 31b1 and 31b1 are formed on the inner sides of the left and right side portions, and slits are cut into the upper surface portion from the rear end. 31b2 is formed. By forming the slit 31b2, the deformation of the pivot protrusions 31b1 and 31b1 on both the left and right side portions can be easily changed due to the elastic deformation of the connecting housing 31b. The pivot protrusions 31b1 and 31b1 are formed coaxially and are arranged to face each other.
As shown in FIGS. 45B and 46, the rear portion 22 of the HMD temple 20 is inserted from the rear of the connection housing 31b. The rear portion 22 includes, from the front, a hinge connecting portion 22a that is connected to the shaft hinge 21a, a support portion connecting portion 22b that is connected to the connecting housing 31b, and a cylindrical portion 22c.
The rear portion 22 is inserted from the rear of the connection housing 31b, the hinge connection portion 22a is protruded forward from the connection housing 31b, and the support portion connection portion 22b is fitted into the connection housing 31b. Guide grooves 22b1 and 22b1 extending in the front-rear direction are formed in the left and right side surfaces of the support portion connecting portion 22b. Pivot protrusions 31b1 and 31b1 are fitted in the guide grooves 22b1 and 22b1, and the support portion connecting portion 22b is fixed by pushing the connecting housing 31b left and right. Thereby, the support part 30 and the HMD temple 20 are fitted and connected by an elastic friction fit.

  As shown in FIG. 47, the inner upper and lower surfaces of the connecting housing 31b are inclined so as to widen the upper and lower surfaces from the pivot protrusion 31b1 toward the front and rear opening ends. As shown in FIGS. 48A and 48B, when the support portion connecting portion 22b comes into contact with the inclined surface 31b3, the vertical rotation of the support portion 30 around the pivot protrusion 31b1 is restricted to a desired angle range.

As described above, the support portion 30 is formed to be substantially parallel to the longitudinal direction of the HMD temple 20 and is connected to the HMD temple 20 so that it can be rotated vertically and horizontally at the rear end portion close to the ear side. Yes. The rubber pad 33, which is a part in contact with the support portion 30, specifically, the HMD temple 20, is formed to be substantially parallel to the longitudinal direction of the HMD temple 20, thereby ensuring a large contact area between the rubber pad 33 and the temple 101. The anti-slip effect can be maximized.
Further, the pivot protrusions 31b1 and 31b1 can be moved by frictional sliding along the guide grooves 22b1 and 22b1. Therefore, the support part 30 is connected along the HMD temple 20 so as to be able to slide back and forth.
Further, the support portion 30 and the HMD temple 20 are fitted and connected by an elastic friction fit so that the operation of the arrangement of the support portion 30 with respect to the HMD temple 20 is allowed and is stably held in an arbitrary arrangement. The operation of the arrangement that receives the action of the friction fitting is the vertical rotation, the horizontal rotation, and the back-and-forth slide movement of the support portion 30 with respect to the HMD temple 20.

The movable function of the support part 30 described above has the following effects.
As shown in FIG. 49A, when the glasses worn by the wearer H are relatively small glasses 100A, the rubber pad 33 is rotated inward to adjust the position so as to be placed on the temple of the glasses 100A. be able to.
As shown in FIG. 49B, when the glasses worn by the wearer H are relatively large glasses 100B, the rubber pads 33 are rotated and arranged so that the glasses H are placed on the temples of the glasses 100B. be able to.
The position adjustment to the inside and the outside of the rubber pad 33 can also be achieved by moving the entire HMD temple 20 along the guide hole 10a described above. On the other hand, the function by the left and right rotation of the rubber pad 33 is different in that it moves independently with respect to the HMD temple 20. Therefore, even after the position when the HMD temple 20 is mounted is determined, the rubber pad 33 can be moved independently from side to side.

As shown in FIGS. 50A and 50B, a case where the head mounted display 1 </ b> A is mounted while being supported by glasses 100 </ b> C whose upper end of the front part is higher than the temple and whose drop is relatively large will be described.
As shown in FIG. 50A, when the HMD temple 20 is straight from the front part 21 to the rear part 22, the rubber pad 33 may float from the temple of the glasses 100C. In this case, as shown in FIG. 50B, by bending the HMD temple 20 with the shaft hinge 21a, the support portion 30 can be lowered and the rubber pad 33 can be brought into contact with the temple of the glasses 100C. At that time, the support part 30 is appropriately rotated up and down to make the lower surface of the rubber pad 33 parallel to the upper surface of the temple of the glasses 100C, and a large contact area between the rubber pad 33 and the temple can be secured.

As shown in FIG. 51A and FIG. 51B, the head mounted display 1A is mounted by supporting it on the glasses 100D having the same upper end height of the temple and the front part, or having the upper end of the front part higher than the temple and having a relatively small drop. Mention the case.
Also in this case, the support part 30 is appropriately rotated up and down so that the lower surface of the rubber pad 33 is parallel to the upper surface of the temple of the glasses 100D, and a large contact area between the rubber pad 33 and the temple can be secured.
The image display unit a moves up and down by rotating the front portion 21 around the shaft hinge 21a, such as from the state of FIG. 51A to the state of FIG. 51B or from the state of FIG. 51B to the state of FIG. The height position of the display part a11 can be adjusted.
The connection at the shaft hinge 21a is also configured to frictionally slide with an appropriate resistance force.

It is possible to adjust the position of the rubber pad 33 in the front-rear direction by sliding the support part 30 back and forth. Thereby, the front-back direction position of the rubber pad 33 can be adjusted according to the shape of the glasses 100 (100C, 100D). For example, the rubber pad 33 is arranged on the flat surface or large area of the glasses 100 (100C, 100D), or the front end of the rubber pad 33 is hung from the temple of the glasses 100 (100C, 100D) to the front part. It is possible to prevent a forward shift by abutting.
Further, the position of the rubber pad 33 in the front-rear direction can be appropriately adjusted according to the shape of the face of the wearer H. For example, when the rubber pad 33 strongly hits the side of the face, it may be avoided by adjusting the position of the rubber pad 33 in the front-rear direction.
The forward / backward slide movable amount of the support portion 30 can be increased by forming the support portion connecting portion 22b and the guide grooves 22b1 and 22b1 in a long shape.

38A, FIG. 38B, FIG. 39A, FIG. 39B, and FIG. 40 and as described above, the image display unit a is configured to be vertically installable without being removed from the main frame 10. The arm 14 to which the image display unit a is attached and the left and right latch portions 16L and 16R (see FIG. 34) can be rotated up and down around the X axis. That is, a vertical rotation support mechanism (turning angle adjustment mechanism) of the image display unit a is configured. Since the rotation axis is away from the display unit a11, not only the turning angle of the display unit a11 but also the height position of the display unit a11 is changed with the vertical rotation of the image display unit a.
50A, 50B, 51A, and 51B can be used to further adjust the turning angle and height position of the display unit a11 using the vertical rotation support mechanism (turning angle adjustment mechanism) of the image display unit a. The display part a11 can be adjusted to an appropriate position by cooperating the vertical rotation of the image display unit a and the movement of the HMD temple 20.

Next, the left / right conversion of the image display unit a will be described.
The head mounted display 1A can be switched between a right-eye display mode and a left-eye display mode.
First, from the form of the right eye display shown in FIG. 52A, the image display unit a is turned upside down in the process of FIG. 38A → FIG. 38B → FIG. 39A → FIG. 39B → FIG.
Next, as shown in FIG. 52B, when the head mounted display 1A is rotated by 180 ° around the Y axis as shown by the arrow R, the state shown in FIG. 53A is obtained. Is done. However, since the rubber pad 33 faces upward as shown in FIG. 53A, the support portion 30 is rotated by 180 ° around the Y axis to the state shown in FIG. 53B, and the support portion 30 can be used.
As shown in FIG. 54A → FIG. 54B, the rotation operation of the support portion 30 about the Y axis is performed by first moving the support portion 30 rearward with respect to the rear portion 22 of the HMD temple 20 to move the connection housing 31b to the support portion. It separates from the connecting portion 22b and is disposed on the cylindrical portion 22c. The cylindrical portion 22c is configured to have a small diameter so that the connecting housing 31b rotates. Therefore, the support part 30 can be rotated 180 ° around the Y axis. In other words, the support portion 30 is configured to be capable of 180 ° change installation around the longitudinal axis of the HMD temple 20 while being held by the HMD temple 20.
As shown in FIG. 54B → FIG. 54C, when the support portion 30 can be turned 180 °, the support portion 30 is returned to the front and the connection housing 31b is fitted to the support portion connection portion 22b.
Since the 180 ° switching mechanism including the connection housing 31b and the cylindrical portion 22c as described above is configured, it is possible to prevent the support portion 30 from being lost without removing the support portion 30 and to be unexpected. It is possible to prevent the support 30 from falling off.

According to the above embodiment, the image display unit a does not contact the face of the wearer, and the display unit right extending unit 11R and the display unit left extending arranged on the left and right sides of the image display unit of the main frame 10 are provided. Since the projecting portion 11L does not come into contact with the face of the wearer, the heat generated by the image display unit a can be released to the display portion right extending portion 11R and the display portion left extending portion 11L to dissipate heat. Without providing a large heat radiating member in a, it is possible to constitute a head mounted display having good small size and light weight and heat radiating property and excellent in wearability and quality retention.
By providing the bridge portion 12 in the middle of the main frame 10, the rear surface a21 of the housing a20 can be disposed behind the display portion right extending portion 11R and the display portion left extending portion 11L. Even if the bridge main part 12M (cover 13) of the bridge part 12 is attached in contact with the face of the wearer, the display part right extension part 11R and the display part left extension part 11L are more than the bridge main part 12M.

Since the image display unit a is not rotated by 180 degrees or more with respect to the arm 14, an accident in which the cable 40 is disconnected by rotating the image display unit a in one direction too much can be prevented.
Since the second hinge 14b of the arm 14 is arranged near the center of the main frame 10 and the cable 40 is pulled out to the opposite side across the second hinge 14b, the right and left weight balance of the head mounted display 1A is good and mounted. Improves.
Since the HMD temples 20 and 20 are provided with the support portions 30 and 30 for the glasses, they can be mounted on the glasses, and the load of the head mounted display 1A is received in the vertical direction by the glasses, so a pair of HMD temples The head-holding force by 20 and 20 is minimal, and the wearability is improved.

Moreover, according to the above embodiment, since the pair of support portions 30 supported in contact with the glasses 100 is disposed between the hinge portion (21b) at the front end of the HMD temple 20 and the ear H1, the weight of the head mounted display 1A is The glasses 100 are not concentrated on the front part of the glasses 100, are distributed in the ears and nose, have a good left / right balance, and exhibit an excellent wearability that is stable and difficult to feel weight.
In addition, since it is not affected by the shape of the front frame of the glasses 100, it can be used without limitation on the type of glasses.
Since the support part 30 is movably held vertically and horizontally, the support part 30 can be flexibly attached to the shape of the temple 101 of the glasses 100, and the anti-slip effect can be effectively exhibited.
According to the present embodiment, since the support portion 30 is held rotatably around the longitudinal axis of the HMD temple 20, the image display unit a is inverted vertically and horizontally with respect to the main frame 10, and the main frame 10 is inverted vertically and horizontally. Thus, even when the arrangement of the display part a11 is switched to the left and right, the support part 30 can be directed to the temple 101 side of the glasses 100, and a mounting form supported using the support part 30 can be taken.

  INDUSTRIAL APPLICABILITY The present invention can be used as a head mounted display that is attached to the head of a human body and allows the wearer to visually recognize an image.
