The first protrusion amount protruding from the tool is the first contact portion. And a coupling mechanism having a second projection amount smaller engagement portions than projecting from the attachment to the direction of separation, and, in the second part of the attachment, the first direction than the particular position At least a part of the other side part is provided on a surface facing the inside of the region, and a second contact part protruding in the separation direction, and a surface facing the inside of the region at least a part of the first part of the wearing tool And a third abutting portion projecting in the separating direction, wherein the engaging portion of the coupling mechanism has the first projecting amount and the second abutting portion from the mounting tool in the separating direction. The end portion on the other side of the first direction from a position that is smaller than the third projecting amount and that is a predetermined distance away from the specific position toward the other side in the first direction at the second portion of the wearing tool. The part up to the position of The second abutting portion is provided on a surface facing the inside of the region in at least a part of the protruding portion, protrudes in the separation direction, and the engaging portion of the coupling mechanism includes the first engaging portion. There is provided a head mounted display in which one protrusion amount is smaller than a fourth protrusion amount in which the protrusion portion protrudes in the separation direction .

  The head-mounted display (HMD) according to the first aspect is mounted on the user's head, for example, with the second direction facing the left-right direction and one side of the first direction being the front side. The first abutting portion comes into contact with the frontal portion of the user. The specific position to which the image display device and the arm unit are connected in the wearing tool is located in the frontal side of the user. The first protrusion amount at which the engaging portion of the coupling mechanism that engages at a specific position protrudes to the inside of the region, that is, the head side when the HMD is mounted, is larger than the second protrusion amount at which the first abutment portion protrudes to the head side. small. Therefore, the engaging portion is unlikely to contact the user's head when the HMD is mounted.

First projection amount engagement portion of the consolidation mechanism protrudes from the attachment to the head side at the time of the HMD is smaller than the third protrusion amount the second contacting portion projects into the head side. A specific position is located between the part in which the 1st contact part was provided, and the part in which the 2nd contact part was provided. Therefore, the engaging portion is unlikely to contact the user's head when the HMD is mounted.

At the position 17, the boundary between the curved shape of the left front portion 56 and the curved shape of the left rear portion 57 is located.

  The radial direction of the curvature circle in contact with the surface facing the inside of the region 10 of the wearing tool 5 in plan view is defined as the thickness direction of the wearing tool 5. The sizes in the thickness direction of the middle front portion 53, the right front portion 54, and the left front portion 56 of the mounting tool 5 are substantially the same size. The sizes in the thickness direction of the right rear portion 55 and the left rear portion 57 are the thicknesses of the protrusions 66 and 67 (described later) with respect to the sizes in the thickness direction of the middle front portion 53, the right front portion 54, and the left front portion 56, respectively. Large by the size of the direction. The sizes in the vertical direction of the middle front portion 53, the right front portion 54, and the left front portion 56 are substantially the same. The sizes of the right rear portion 55 and the left rear portion 57 in the vertical direction gradually increase from the front side to the rear side, and are the largest in the vicinity of the end portions 62 and 63 and gradually toward the end portions 62 and 63. Becomes smaller.

  Projections 66 and 67 projecting into the region 10 are formed in the right rear portion 55 and the left rear portion 57, respectively. The protrusions 66 and 67 are provided in a form in which the inner surfaces 70 and 71 facing the inside of the region 10 of the right rear portion 55 and the left rear portion 57 are stepped out in the thickness direction toward the region 10. Therefore, the inner surfaces 70 and 71 each have a curved surface shape that follows the curved shapes of the right rear portion 55 and the left rear portion 57. Accordingly, the vertical sizes of the protrusions 66 and 67 are also gradually increased from the front side toward the rear side, are largest in the vicinity of the end portions 62 and 63, and gradually decrease toward the end portions 62 and 63.

  Holding grooves 68 and 69 extending in a groove shape along the circumferential direction with respect to the protruding direction are formed on the side surfaces of the protruding portions 66 and 67 with respect to the protruding direction (that is, the thickness direction), respectively.

  The wearing tool 5 includes pads 75 to 77 that come into contact with the user's head when worn. The pads 75 to 77 are made of an elastic resin such as a silicon resin. The pad 75 is provided on the inner surface 72 facing the inside of the region 10 in the middle front portion 53 and including the position 21 at the center in the left-right direction of the wearing tool 5. The pad 75 extends in the left-right direction along the curved shape of the middle front portion 53 and protrudes in a direction away from the inner surface 72 (for example, rearward in FIG. 2) along the thickness direction. The size of the pad 75 in the vertical direction is substantially the same as or smaller than the size of the mounting tool 5 in the middle front portion 53 in the vertical direction. When the HMD 1 is mounted, the pad 75 contacts the forehead or frontal portion of the user and positions the mounting tool 5 on the head.

  The pads 76 and 77 are provided on the inner surface 70 of the right rear portion 55 and the inner surface 71 of the left rear portion 57, respectively. The pad 76 extends along the curved shape of the right rear portion 55 and protrudes in the thickness direction toward the region 10. The length in which the pad 76 extends in the direction along the curved direction of the right rear portion 55 is shorter than the length of the right rear portion 55. The vertical size of the pad 76 is substantially the same as or smaller than the vertical size of the right rear portion 55. The vertical size of the pad 76 is larger than the vertical size of the middle front portion 53, the right front portion 54, and the left front portion 56. In the present embodiment, the pad 76 is provided on the inner surface 70 at a portion from the approximate center in the direction along the curved shape of the right rear portion 55 to the end portion 62. The pad 77 extends along the curved shape of the left rear portion 57 and protrudes in the thickness direction toward the region 10. The length in which the pad 77 extends in the direction along the curved direction of the left rear portion 57 is shorter than the length of the left rear portion 57. The vertical size of the pad 77 is substantially the same as or smaller than the vertical size of the left rear portion 57. Further, the size of the pad 77 in the vertical direction is larger than the size in the vertical direction of the middle front portion 53, the right front portion 54 and the left front portion 56. In the present embodiment, the pad 77 is provided on the inner surface 71 at a portion from the substantially center to the end portion 63 in the direction along the curved shape of the left rear portion 57.

  As described above, the mounting tool 5 has flexibility. When the HMD 1 is mounted, the mounting tool 5 is separated by being pushed and spread by the user's hand with the end 62 and the end 63 facing the outside of the region 10 (for example, in the left-right direction). When the wearing tool 5 is fitted to the user's head, the pad 75 contacts the user's forehead or forehead, thereby positioning the wearing tool 5 in the front-rear direction on the head. When the expanded state of the end portions 62 and 63 is released, the right rear portion 55 and the left rear portion 57 of the mounting tool 5 are urged toward the inside of the region 10. The pads 76 and 77 are in contact with the right and left heads of the user, respectively. The inner surface 70 of the right rear portion 55 presses the right side of the user through the pad 76. Similarly, the inner surface 71 of the left rear portion 57 presses the left side of the user via the pad 77. The right rear portion 55 and the left rear portion 57 of the mounting tool 5 obtain a pressing force that presses the user's temporal region, and holds the user's head across the head. As described above, the inner surfaces 70 and 71 that are formed large in the vertical direction have a larger area in contact with the user's temporal region than the inner surface 72 of the middle front portion 53. Therefore, when the mounting tool 5 is mounted on the user's head, the pads 76 and 77 obtain a large frictional force with the head by increasing the contact area with the head. By ensuring the friction area, the wearing tool 5 can suppress the occurrence of positional deviation in the head. The pads 76 and 77 have a larger area in contact with the user's temporal region than the pad 75. Therefore, the right rear portion 55 and the left rear portion 57 can disperse the pressing force that presses the temporal region through the pads 76 and 77, respectively. That is, the HMD 1 can reduce the pressing force per unit area received by the user on the rear side head. Therefore, the user is less likely to feel pressure on the temporal region.

  Attachment portions 58 and 59 are provided at portions between the front end portion 61 on the front side in the front-rear direction and the end portions 64 and 65 on both sides in the left-right direction, respectively. The position 15 </ b> A where the attachment portion 58 is provided is a position on the right side of the position 21 and on the front side of the position 22. As described above, the position 22 is located at the center of the wearing tool 5 in the front-rear direction. More specifically, the position 15 </ b> A where the attachment portion 58 is provided is a position between the portion where the pad 75 is provided and the portion where the protrusion 66 is provided in the mounting tool 5. The position 15 </ b> B where the attachment portion 59 is provided is a position on the left side of the position 21 and on the front side of the position 22. More specifically, the position 15B where the attachment portion 59 is provided is a position between the portion where the pad 75 is provided and the portion where the protruding portion 67 is provided in the mounting tool 5. The attachment tool 5 can attach the connection mechanism 8 that connects the attachment tool 5 and the arm part 4 to the attachment parts 58 and 59. In the present embodiment, the coupling mechanism 8 is attached to the attachment portion 59. The connection mechanism 8 will be described later.

  Two holes 58A penetrating the wearing tool 5 in the thickness direction are formed in the attachment portion 58 (see FIG. 1). Similarly, two holes (not shown) penetrating the mounting tool 5 in the thickness direction are also formed in the attachment portion 59. A screw 60 (see FIG. 7) is inserted through the hole 58A. The connection mechanism 8 is attached to the attachment portions 58 and 59 by screws. That is, the image display unit 2 including the image display unit 3, the arm unit 4, and the coupling mechanisms 8 and 9 can be attached by selecting one of the attachment unit 58 and the attachment unit 59. When the image display unit 2 is attached to the attachment portion 58, the image display portion 3 is disposed on the right side of the wearing tool 5. The image display unit 3 can cause image light to enter the right eye of the user. When the image display unit 2 is attached to the attachment portion 59, the image display portion 3 is disposed on the left side of the wearing tool 5. The image display unit 3 can cause image light to enter the left eye of the user.

In the base end portion 31 </ b> B, a fixing portion 94 of the coupling mechanism 9 is connected to a position on the rear surface of the housing 31 on the right side of the protruding portion 32. The connection mechanism 9 will be described later.

  An image unit 37 is provided in the housing 31 at the base end portion 31B. The image unit 37 includes a known liquid crystal panel (not shown) and a control board (not shown). The liquid crystal panel generates image light by displaying an image on the left side. The control board is disposed on the right side of the liquid crystal panel. A cable 39 is connected to the control board. The cable 39 passes through the protrusion 32 and is drawn out of the image display unit 3 from the hole at the rear end of the protrusion 32. The control board receives image data transmitted from the external device via the cable 39. The control board outputs a control signal to the liquid crystal panel and displays an image corresponding to the image data on the liquid crystal panel. Instead of the liquid crystal panel, a two-dimensional display device such as a digital mirror device (DMD) or an organic EL may be used. Further, instead of the liquid crystal panel, a retinal scanning type projection device (Retinal Scanning Display) that projects two-dimensionally scanned light onto the retina of the user may be used.

  In the housing 31, a lens unit 36 is provided on the right side of the image unit 37. The lens unit 36 allows the image light emitted from the image unit 37 to pass therethrough and guides it to the distal end portion 31A side. The lens unit 36 includes a plurality of lenses (not shown). The lens unit 36 is held by the housing 31 so as to be movable in the left-right direction. An operation member 38 having a truncated cone shape and having a plurality of irregularities on the side surface is provided on the front surface of the housing 31. The operation member 38 is engaged with the lens unit 36 by a groove cam (not shown). When the operation member 38 is rotated, the lens unit 36 moves toward the distal end portion 31A side or the proximal end portion 31B side. As the lens unit 36 moves in the left-right direction, the focal length of the image light emitted from the image unit 37 changes. Therefore, the user can adjust the focus by rotating the operation member 38.

  A half mirror 35 is provided at the tip 31A. The half mirror 35 has a rectangular plate shape. The half mirror 35 can reflect a part (for example, 50%) of the light incident on the reflecting surface and transmit the other part. The reflective surface of the half mirror 35 is formed, for example, by vapor-depositing a metal such as aluminum or silver on a transparent resin or glass substrate so as to have a predetermined reflectance (for example, 50%). When the HMD 1 is mounted, the base end portion 31B of the housing 31 is disposed on the left side of the tip end portion 31A. That is, the image display unit 3 is used in a state of being arranged extending in the left-right direction. The half mirror 35 is disposed in front of the user's left eye, for example. Half mirror 35 is fixed to tip part 31A in the state where the reflective surface turned to the left side and the back side. The image light emitted from the image unit 37 in the housing 31 is condensed when passing through the lens unit 36. The condensed image light is incident on the half mirror 35. The half mirror 35 reflects the image light to the rear side and makes it incident on the left eye of the user. The user can visually recognize a virtual image based on the image light reflected by the half mirror 35. Further, the half mirror 35 can transmit external light incident from the front side to the rear side.

  As shown in FIGS. 1 to 3, 5, and 6, the arm portion 4 is made of resin, metal, or the like, and extends in a rod shape. The upper end portion 4 </ b> A of the arm portion 4 is connected to the mounting tool 5 by the connecting mechanism 8. The lower end 4 </ b> B of the arm unit 4 is connected to the image display unit 3 by the connecting mechanism 9. The arm unit 4 holds the image display unit 3 at a position separated from the mounting tool 5. As shown in FIG. 1, when the HMD 1 is mounted, the lower end 4B of the arm unit 4 is disposed on the lower side and the left side of the upper end 4A. The arm portion 4 is curved in a convex shape toward the outside of the region 10. In the present embodiment, the arm portion 4 is curved in a convex shape toward the left when the HMD 1 is mounted.

  As shown in FIGS. 5 and 6, the arm portion 4 includes a connection portion 41 at the upper end portion 4A. The connection portion 41 is a portion where the arm portion 4 is connected to the coupling mechanism 8. The connection portion 41 protrudes along the predetermined direction B (see FIG. 5) at the upper end portion 4A. The direction B is a direction in which the arm part 4 is inclined with respect to a direction C extending from the upper end part 4A toward the lower end part 4B. The connecting portion 41 is formed with a hole (not shown) extending along the direction B. A rod body of a ball stud 81 (described later) of the coupling mechanism 8 is inserted into the hole. That is, the rod body of the ball stud 81 extends along the direction B. The arm portion 4 is connected to the coupling mechanism 8 by fixing the rod body to the connection portion 41.

  The coupling mechanism 8 has two or more rotational degrees of freedom. The connection mechanism 8 of this embodiment is a known ball joint type movable part. The coupling mechanism 8 includes a ball stud 81, a socket accommodating portion 82, a fixing nut 83, and an engaging portion 84. The ball stud 81 is a component in which a rod is connected to a sphere. The socket accommodating portion 82 has a cylindrical shape, and accommodates a socket (not shown) that makes spherical contact with the sphere of the ball stud 81. The fixing nut 83 is a lid that can be externally fitted to the opening of the socket housing portion 82 and fastened. The fixing nut 83 is formed with an insertion hole (not shown) through which the rod body of the ball stud 81 is inserted. The ball stud 81 has a movable range in which the rod body can move within the insertion hole with a sphere in contact with the socket as a fulcrum. As shown in FIG. 5, when the shaft of the rod is located at the center of the insertion hole, the ball stud 81 is located at the center of the movable range. At this time, the extending direction of the rod body of the ball stud 81, that is, the extending direction B of the connecting portion 41 coincides with a direction A (see FIG. 1) described later. That is, the movable range of the ball stud 81 is, for example, a predetermined solid angle (that is, within the range of the conical surface) with the direction A as the central axis. When the fixing nut 83 is fastened to the socket housing portion 82, the ball stud 81 is positioned with respect to the socket housing portion 82 by pressing the spherical body against the socket.

  The engaging portion 84 is provided at the end portion of the socket housing portion 82 opposite to the side on which the fixing nut 83 is fitted (that is, the right end portion of the socket housing portion 92). The engaging part 84 is a part for attaching the coupling mechanism 8 to the attaching parts 58 and 59 of the mounting tool 5. As shown in FIGS. 5 to 7, the engaging portion 84 includes an upper wall 85, an inner wall 86, and an outer wall 87. The upper wall 85 is a portion that abuts on an upper surface of the mounting portion 58, 59 that faces upward when the HMD 1 is mounted on the head, of the side surface of the mounting tool 5. The shape of the upper wall 85 is a plate shape that extends while being curved along the curved shape of the wearing tool 5. The plate surface of the upper wall 85 is planar. The lower plate surface of the upper wall 85 abuts on the upper surface of the mounting tool 5. The size of the upper wall 85 in the thickness direction of the mounting tool 5 is a size obtained by adding the thickness of the inner wall 86 and the outer wall 87 to the size of the mounting tool 5 in the thickness direction. The outer side wall 87 is a part that contacts the outer surface on the opposite side to the inner surface facing the inside of the region 10 among the side surfaces of the mounting tool 5 in the attachment portions 58 and 59. The outer wall 87 has a plate shape. The plate surface inside the region 10 of the outer wall 87 abuts on the outer surface of the mounting tool 5. The plate surface of the outer side wall 87 is orthogonal to the thickness direction of the wearing tool 5. The plate surface inside the region 10 of the outer wall 87 faces the outer surface of the wearing tool 5 and extends in the front-rear direction while gently bending in the vertical direction. Outer side wall 87 projects downward from the end of region 10 outside the end of upper wall 85. Two holes 87 </ b> A (see FIG. 6) penetrating in the thickness direction of the mounting tool 5 are formed in the outer side wall 87. The inner side wall 86 is a part that contacts the inner surface facing the inside of the region 10 among the side surfaces of the mounting tool 5 in the attachment portions 58 and 59. The shape of the inner wall 86 is a plate shape that is narrower in the front-rear direction than the outer wall 87. A plate surface outside the region 10 of the inner wall 86 abuts on the inner surface of the mounting tool 5. The plate surface of the inner wall 86 is orthogonal to the thickness direction of the wearing tool 5. The inner side wall 86 protrudes downward from the end portion inside the region 10 among the end portions of the upper wall 85. The inner wall 86 is not provided at a position that overlaps the formation range of the hole 87 </ b> A of the outer wall 87 in the thickness direction of the wearing tool 5.

  When the engaging portion 84 is attached to the attaching portions 58 and 59, the engaging portion 84 is disposed on the attaching portions 58 and 59 from the upper side of the attaching portions 58 and 59. The inner wall 86 and the outer wall 87 sandwich the attachment portions 58 and 59 therebetween. In the engaging portion 84, the inner wall 86 and the end connected to the inner wall 86 of the upper wall 85 protrude into the region 10 rather than the mounting tool 5. The size of the engaging portion 84 protruding into the region 10 is the size of the inner wall 86 in thickness. A screw 60 is inserted into the hole 58 </ b> A (see FIG. 1) of the mounting tool 5 and the hole 87 </ b> A of the outer wall 87 from the inside of the region 10. The outer side wall 87 has a bag-like accommodation portion 87B that accommodates a nut (not shown) at a position where the hole portion 87A is formed on the plate surface outside the region 10. The engagement portion 84 is fixed to the attachment portions 58 and 59 by fastening the screw 60 to the nut in the accommodation portion 87B. The thickness of the head of the screw 60 after fastening is smaller than the thickness of the inner wall 86. The screw 60 after fastening does not protrude into the region 10 more than the inner wall 86 in the thickness direction of the wearing tool 5.

  As shown in FIGS. 5 and 6, the arm portion 4 includes a connection portion 42 at the lower end portion 4B. The connecting portion 42 is a portion where the arm portion 4 is connected to the coupling mechanism 9. The connection part 42 protrudes along the direction B substantially the same as the connection part 41 in the lower end part 4B. The connecting portion 42 is also formed with a hole (not shown). A rod body of a ball stud 91 (described later) of the coupling mechanism 9 is inserted into the hole. That is, the rod body of the ball stud 91 extends along the direction B. The arm portion 4 is connected to the coupling mechanism 9 by fixing the rod body to the connection portion 42.

  The connection mechanism 9 has two or more rotational degrees of freedom. As shown in FIGS. 4 and 5, the connection mechanism 9 of the present embodiment is a known ball joint type movable part, like the connection mechanism 8. The connection mechanism 9 includes a ball stud 91, a socket housing portion 92, a fixing nut 93, and a fixing portion 94. The configurations of the ball stud 91, the socket accommodating portion 92, and the fixing nut 93 are the same as those of the coupling mechanism 8. When the shaft of the ball stud 91 is positioned at the center of the insertion hole (not shown) of the fixing nut 93, the ball stud 91 is positioned at the center of the movable range. At this time, the extending direction of the rod body of the ball stud 91, that is, the extending direction B of the connecting portion 42 coincides with the direction A (described later). That is, the movable range of the ball stud 91 is, for example, a predetermined solid angle (that is, within the range of the conical surface) with the direction A as the central axis.

  The fixing portion 94 is provided at the end of the socket housing portion 92 opposite to the side on which the fixing nut 93 is fitted. The fixing unit 94 is a component that fixes the coupling mechanism 9 to the image display unit 3. The fixing part 94 includes a first fixing part 95, a second fixing part 96, and a stepped connection part 97. The first fixing portion 95 is connected to the socket accommodating portion 92. The first fixing portion 95 is located on the rear side of the protruding portion 32. The left end of the first fixing portion 95 to which the socket accommodating portion 92 is connected is located slightly to the left of the left end of the protruding portion 32. The second fixing portion 96 is located forward and to the right of the first fixing portion 95. The second fixing part 96 is located on the right side of the protruding part 32 on the rear surface of the image display part 3. The second fixing unit 96 is connected to the image display unit 3. For example, the second fixing portion 96 is connected to the base end portion 31 </ b> B of the image display portion 3 on the rear side of the half mirror 35 in the front-rear direction. The step-like connecting portion 97 connects the first fixing portion 95 and the second fixing portion 96 in a step shape. The step-like connecting portion 97 extends from the front portion of the first fixed portion 95 across the rear end of the protruding portion 32 in the left-right direction. The step-like connecting portion 97 further extends to the left side portion of the second fixing portion 96 along the protruding portion 32 on the right side of the protruding portion 32. A hole 97A penetrating in the front-rear direction is formed in a portion where the stepped connection portion 97 crosses the rear end of the protruding portion 32. The cable 39 led out from the hole at the rear end of the protrusion 32 is inserted into the hole 97A.

  The HMD 1 having the above configuration takes the form described below when the image display unit 2 is attached to the attachment portion 58 and the coupling mechanisms 8 and 9 are in the center of the movable range. As shown in FIG. 1 and FIG. 2, a direction A that passes through the position 15B where the attachment portion 59 is provided and goes from the inside of the region 10 to the outside is defined as a direction A. The coupling mechanism 8 is provided so as to protrude to the outside of the region 10 in the direction A with respect to the mounting tool 5. The upper end portion 4 </ b> A of the arm portion 4 is connected to the coupling mechanism 8 on the outer side of the region 10 in the direction A than the coupling mechanism 8. The lower end 4B of the arm part 4 is disposed below the upper end 4A. The coupling mechanism 9 is connected to the proximal end portion 31 </ b> B of the image display unit 3 on the rear side of the image display unit 3. Since the housing 31 of the image display unit 3 extends in the left-right direction, the distal end portion 31A is disposed to the right of the proximal end portion 31B. The half mirror 35 is disposed in front of the left eye of the user.

  When the HMD 1 is worn, the pad 75 of the wearing tool 5 comes into contact with the user's forehead or forehead. Since the pad 75 is curved along the curved shape of the middle front portion 53, the pad 75 is adapted to the shape of the user's forehead or frontal head. The pads 76 and 77 abut against the user's temporal region. Since the pads 76 and 77 are curved along the curved shapes of the right rear portion 55 and the left rear portion 57, respectively, the pads 76 and 77 become familiar with the shape of the user's temporal region. In order to obtain a pressing force by which the right rear portion 55 and the left rear portion 57 press the user's temporal region, the right front portion 54 and the left front portion 56 of the wearing tool 5 are composed of the middle front portion 53, the right rear portion 55, and the left rear portion. Curved with a greater curvature than portion 57. The right rear portion 55 and the left rear portion 57 are curved with a curvature larger than the curved shape of the user's head. Therefore, the wearing tool 5 is not familiar with the shape of the user's head in the portion between the portion where the pad 75 is provided and the portion where the pads 76 and 77 are provided, and there is a gap between the head and the head. Have Therefore, the engaging portion 84 of the coupling mechanism 8 fixed to the attachment portions 58 and 59 provided between the pad 75 and the pads 76 and 77 is difficult to contact the user's head.

  In the present embodiment, by providing the following rules, the HMD 1 further realizes a structure in which the engaging portion 84 and the user's head are unlikely to contact each other. In the present embodiment, the engaging portion 84 is fixed to the attachment portion 59. As shown in FIG. 2, the length between the portion where the pad 75 is provided and the position 15 </ b> B is a length along the curved shape of the wearing tool 5 and is L <b> 1. The length along the curved shape of the wearing tool 5 and the length between the position 15B and the portion where the pad 77 is provided is L2. In this case, the HMD1 satisfies L1 <L2. That is, the position 15B is closer to the portion where the pad 75 is provided than the portion where the pad 77 is provided. The right rear portion 55 and the left rear portion 57 are elastically deformed with the pads 76 and 77 larger than the pad 75 in order to obtain a pressing force that presses the user's temporal region. Since the attachment portion 59 is provided at a position close to the pad 75 with small deformation, the engagement portion 84 is unlikely to approach the user's head when the HMD 1 is worn.

  As described above, the engaging portion 84 fixed to the attachment portion 59 protrudes into the region 10 by the thickness of the inner wall 86. A size that the engaging portion 84 protrudes in the thickness direction from the inner surface of the mounting tool 5 in the attachment portion 59 into the region 10 is defined as a protruding amount P1. A size in which the pad 75 protrudes in the thickness direction from the inner surface 72 in the middle front portion 53 into the region 10 is defined as a protrusion amount P2. In this case, the HMD1 satisfies P1 <P2. That is, the protruding tip of the pad 75 is located inside the region 10 relative to the engaging portion 84. Therefore, when mounted, the HMD 1 can provide a gap between the engaging portion 84 and the user's head by the pad 75.

  A size that the pad 77 protrudes in the thickness direction from the inner surface 71 of the left rear portion 57 into the region 10 is defined as a protrusion amount P3. The inner surface 71 is located at the protruding tip of the protruding portion 67. In this case, the HMD1 satisfies P1 <P3. By disposing the engaging portion 84 between the pad 75 and the pad 77 having a large protruding amount, the HMD 1 can provide a gap between the engaging portion 84 and the user's head.

    The size of the protruding portion 67 protruding in the thickness direction from the left rear portion 57 into the region 10 is defined as a protruding amount P4. In this case, the HMD1 satisfies P1 <P4. Even if the pad 77 is elastically deformed, the HMD 1 can provide a gap between the engaging portion 84 and the user's head by the protruding portion 67 having a larger protruding amount than the engaging portion 84.

  As described above, the pad 75 provided on the middle front portion 53 of the wearing tool 5 contacts the frontal portion of the user. The position 15B of the attachment portion 59 to which the image display portion 3 and the arm portion 4 are connected in the mounting tool 5 is located on the frontal side of the user. The protrusion amount P1 that the engaging portion 84 of the coupling mechanism 8 that engages with the attachment portion 59 protrudes to the inside of the region 10, that is, the head side when the HMD 1 is mounted, is larger than the protrusion amount P2 that the pad 75 protrudes to the head side. small. Therefore, the engaging portion 84 is unlikely to contact the user's head when the HMD 1 is worn.

  The protrusion amount P1 that the engaging portion 84 of the coupling mechanism 8 protrudes from the mounting tool 5 to the head side when the HMD 1 is mounted is smaller than the protrusion amount P3 that the pad 77 protrudes to the head side. The position 15B of the attachment portion 59 is located between the portion where the pad 75 is provided and the portion where the pad 77 is provided. Therefore, the engaging portion 84 is unlikely to contact the user's head when the HMD 1 is worn.

  When the HMD 1 is mounted, the head is sandwiched between the portion where the pad 77 is provided and the portion where the pad 76 is provided, and the pad 77 and the pad 76 are brought into contact with the occipital side to obtain a pressing force, respectively. To be worn on the head. On the other hand, the pad 75 contacts the frontal head and positions the wearing tool 5 at the head. Therefore, the pad 77 and the pad 76 may be elastically deformed more greatly than the pad 75. Therefore, by providing the specific position at a position close to the pad 75, the engaging portion 84 is unlikely to contact the user's head when the HMD 1 is worn.

  The protrusion amount P1 at which the engaging portion 84 protrudes into the region 10 is smaller than the protrusion amount P4 at which the protrusion portion 67 protrudes into the region 10. Therefore, even if the pad 77 provided on the inner surface of the mounting tool 5 in the protruding portion 67 is elastically deformed at the time of mounting, the engaging portion 84 whose protruding amount is smaller than that of the protruding portion 67 is difficult to contact the head.

  By fixing the engaging portion 84 to the attachment portion 59 provided at the position 15B, the engaging portion 84 is not displaced from the position 15B during use of the HMD 1. Therefore, the engaging portion 84 is unlikely to contact the user's head when the HMD 1 is mounted.

  When the arrangement position of the image display unit 3 with respect to the user is changed after the HMD 1 is mounted, the mounting tool 5 may receive a torque associated with the swing of the arm unit 4 and may be displaced from the original mounting position. is there. Since the pad 75 protrudes to the head side with respect to the engaging portion 84, the engaging portion 84 is unlikely to contact the user's head even if the wearing tool 5 is displaced.

  The wearing tool 5 is closed on the rear side and opened on the front side. When the HMD 1 is mounted on the head, the ring opening side of the mounting tool 5 is widened, and the HMD 1 is mounted in such a manner that the side of the ring is pressed after the ring closing side is positioned. The position 15B where the attachment portion 59 is provided is located on the front side of the center 22 in the front-rear direction, that is, closer to the ring closing side of the mounting tool 5. Therefore, since the HMD 1 has the image display unit 3 arranged on the ring-closing side, it is easy to position the image display unit 3 with respect to the head.

  When the HMD 1 is mounted, each portion of the mounting tool fits the shape of the user's head and holds the head securely, so that displacement of the mounting position is suppressed.

  In addition, this invention is not limited to the said embodiment, A various change is possible. The protrusions 66 and 67 having the holding grooves 68 and 69 may be omitted. There may be a plurality of pads 75 to 77, and the pads 75 to 77 may be intermittently arranged in the direction along the direction in which the wearing tool 5 is curved. Instead of the half mirror 35, a reflecting member that does not transmit light from the outside and substantially reflects the incident image light may be used. Instead of the half mirror 35, an optical path deflecting member such as a prism or a diffraction grating may be used. The coupling mechanisms 8 and 9 do not have to be ball joint movable parts. For example, any movable part having two or more rotational degrees of freedom by combining two or more hinges may be used. The mounting tool 5 may not be configured to be entirely curved. The curved portion of the mounting tool 5 may be a part of the mounting tool 5. The direction A is not limited to the direction along the left-right direction, and may be any direction that passes from the inside of the region 10 to the outside through the position 15A or the position 15B.

  The mounting tool 5 may be annular. That is, there may be a portion extending between the position 11 and the position 13 as well as the middle front portion 53 extending between the position 12 and the position 14. Alternatively, like the HMD 101 shown in FIG. 8, the wearing tool 105 may have a substantially annular shape with the front side opened. That is, the mounting tool 105 may have a portion that opens between the position 12 and the position 14 and extends between the position 11 and the position 13.

  In this embodiment, the engaging portion 84 of the coupling mechanism 8 is fixed to the attaching portion 59 provided at the position 15B on the left side of the pad 75, but the engaging portion 84 is provided on the attaching portion 58 provided at the position 15A on the right side of the pad 75. May be fixed. In this case, the configuration of the pad 76 and the protruding portion 66 is the same as the configuration of the pad 77 and the protruding portion 67, respectively.
