DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the directions indicated by X1 and X2 in the drawings are the right and left, respectively, the directions indicated by Y1 and Y2 in the drawings are the front and rear, respectively, and the directions indicated by Z1 and Z2 in the drawings are the up and down, respectively. These directions indicate the directions as seen by a user wearing a head-mounted display 1. In the following description, the head-mounted display 1 will be referred to as an HMD (Head Mounted Display) 1.

[0010] [Overview of the overall configuration of HMD1] 1 is a perspective view showing the overall configuration of an HMD according to embodiment 1. As shown in FIG.

[0011] The wearing band 20 extends rearward from the device main body 10. When the HMD 1 is in use, the wearing band 20 surrounds the user's head. The wearing band 20 is annular, and the user's head may be placed inside the wearing band 20.

[0012] The device main body 10 has at least a display 11, a right lens 12R and a left lens 12L (see FIG. 6), and a housing 10a that houses the display 11, the right lens 12R, and the left lens 12L and forms the exterior of the device main body 10. In one example of the HMD 1, the display 11 displays three-dimensional images. However, this is not limited thereto, and the images displayed by the display 11 may be two-dimensional images. The display 11 may be, for example, a liquid crystal display device or an organic electroluminescence display device, but the type is not particularly limited. When the HMD 1 is in use, the device main body 10 covers the user's eyes. The housing 10a may be made of, for example, resin.

[0013] In the first embodiment, an example in which the housing 10a has a built-in display will be described, but the present invention is not limited to this. For example, a mobile terminal may be housed in the device main body 10, and image light from the display of the housed mobile terminal may be guided to the user's eyes. In this case, for example, a smartphone may be used as the mobile terminal.

[0014] The wearing band 20 may be configured to support the device main body 10 so as to be movable in the front-to-rear direction relative to the device main body 10. With such a configuration, the distance between the user's eyes and the right lens 12R and the left lens 12L can be adjusted. Accordingly, the distance of the light-blocking member 30 (described below) from the user's face can be adjusted, thereby adjusting the contact pressure on the user's face. The wearing band 20 may also be configured so that its length can be adjusted to fit the size of the user's head. Note that the wearing band 20 is not limited to the configuration shown in FIG. 1 as long as it is worn on the user's head and supports the device main body 10.

[0015] [Light blocking material] Next, the light blocking member 30 of the first embodiment will be described in detail with reference to FIGS. 2 to 8. FIG. 2 is a perspective view of the light blocking member of the first embodiment as seen obliquely from the front. FIG. 3 is a front view of the light blocking member of the first embodiment as seen from the front. FIG. 4 is a perspective view of the light blocking member of the first embodiment as seen obliquely from the rear. FIG. 5 is a rear view of the light blocking member of the first embodiment as seen from the rear. FIG. 6 is a top view of the light blocking member of the first embodiment as seen from above. FIG. 6 schematically shows part of the internal structure of the device main body 10. FIG. 7 is a bottom view of the light blocking member of the first embodiment as seen from below. FIG. 8 is a perspective view of the light blocking member of the first embodiment as seen obliquely from below.

[0016] The light blocking member 30 is a member provided to block or reduce external light incident on the eyes of a user wearing the HMD 1. The light blocking member 30 is preferably made of an elastic resin. However, the light blocking member 30 is not limited to being made of resin, and may be made of, for example, a fibrous material (such as a sponge).

[0017] The light blocking member 30 includes an attachment portion 31 that is attached to the housing 10a of the device body 10. When viewed from the rear, the attachment portion 31 is preferably annular and surrounds the right lens 12R and left lens 12L housed in the housing 10a. The attachment portion 31 is preferably configured to be detachable from the housing 10a. For example, the attachment portion 31 may have a front portion formed with multiple locking protrusions that fit into multiple grooves formed in the housing 10a, respectively, thereby enabling the light blocking member 30 to be attached to the housing 10a. However, the present invention is not limited to this, and the attachment portion 31 may also be formed and fixed to the housing 10a by two-color molding or insert molding.

[0018] The light-shielding member 30 also includes a light-shielding wall 32 extending rearward from the mounting portion 31. The light-shielding wall 32 extends rearward from the mounting portion 31 so as to come into contact with the area around the eyes of the user wearing the HMD 1. By including the light-shielding wall 32, the light-shielding member 30 functions to block or reduce external light that is incident on the eyes of the user wearing the HMD 1. It is preferable that the mounting portion 31 and the light-shielding wall 32 are integral with each other.

[0019] The light-shielding wall 32 includes an upper portion 321, a right portion 322R, and a left portion 322L. The upper portion 321 is a portion that comes into contact with the upper side of the eye of a user wearing the HMD 1. The right portion 322R is a portion that comes into contact with the right side of the right eye of a user wearing the HMD 1. The left portion 322L is a portion that comes into contact with the left side of the left eye of a user wearing the HMD 1.

[0020] Furthermore, the light-shielding wall 32 includes a right connector 325R that connects the upper portion 321 and the right portion 322R, and a left connector 325L that connects the upper portion 321 and the left portion 322L.

[0021] 6 and 7, the portions corresponding to upper portion 321, right portion 322R, left portion 322L, right connecting portion 325R, and left connecting portion 325L are indicated by dashed circles, respectively. However, since light-shielding wall 32 is made of a single member, the boundaries of each portion are not strictly defined.

[0022] The light-shielding wall 32 has bellows that come into contact with the area around the eyes of a user wearing the HMD 1 and expand and contract (elastically deform) in response to contact pressure. In the first embodiment, an example is shown in which the bellows is provided around the entire periphery of the light-shielding wall 32. That is, an example is shown in which the bellows is provided on each of the upper part 321, the right part 322R, the left part 322L, the right connecting part 325R, and the left connecting part 325L.

[0023] Here, the bellows is formed by alternating mountain ridges and valley ridges. In the first embodiment, the bellows is shown by alternating four mountain ridges M1 to M4 and three valley ridges G1 to G3. To avoid cluttering the drawings, the reference numerals for the mountain ridges and valley ridges are shown only in FIG. 5. The number of mountain ridges and valley ridges is not limited to this and may be more or less than the illustrated example. By increasing the number of mountain ridges and valley ridges, the flexibility of the light-shielding wall 32 can be further improved, while by reducing the number of mountain ridges and valley ridges, the configuration of the light-shielding wall 32 can be simplified.

[0024] In the first embodiment, as shown in FIG. 5 and other figures, notches CR and CL are provided in the innermost mountain ridge portions M1 of the bellows of the right and left portions 322R and 322L. The notches CR and CL are provided in front of the ears of a user wearing the HMD 1 and have a predetermined width in the vertical direction. Because the notches CR and CL are provided in this manner, even when a user wears eyeglasses while wearing the HMD 1, the temples of the eyeglasses do not interfere with the right and left portions 322R and 322L of the baffle wall 32, which would cause deformation of the shape of the baffle wall 32 and create a gap between the baffle wall 32 and the user's face. Furthermore, by preventing the temples of the eyeglasses from interfering with the right and left portions 322R and 322L of the baffle wall 32, the user can comfortably wear the HMD 1 even while wearing eyeglasses.

[0025] The notches CR and CL are preferably provided at least in portions including the innermost mountain stripe portion or valley stripe portion of the right portion 322R and the left portion 322L. For example, the notches CR and CL may be provided across the innermost mountain stripe portion M1 and the valley stripe portion G1 adjacent to the mountain stripe portion M1. Furthermore, for example, when the valley stripe portion is located at the innermost side of the bellows of the right portion 322R and the left portion 322L, the notches CR and CL are preferably provided in the innermost valley stripe portion.

[0026] 6, in the first embodiment, the width W3 of the bellows of right connecting portion 325R and left connecting portion 325L in a top view is wider than the width W1 of the bellows of upper portion 321 and the width W2 of the bellows of right portion 322R and left portion 322L. Due to this configuration, when a user wears HMD 1, the user's head first comes into contact with right connecting portion 325R and left connecting portion 325L. As a result, right connecting portion 325R and left connecting portion 325L are compressively deformed.

[0027] As the right connecting portion 325R and the left connecting portion 325L are compressed and deformed, the right portion 322R moves leftward, and the left portion 322L moves rightward. That is, the right portion 322R and the left portion 322L move in the directions indicated by the arrows in FIGS. 6 and 7. As a result, the user's head is sandwiched between the right portion 322R and the left portion 322L. Specifically, the right portion 322R contacts the right side of the user's right eye with a predetermined contact pressure, and the left portion 322L contacts the left side of the user's left eye with a predetermined contact pressure. In the first embodiment, the right portion 322R moves leftward as the light-shielding wall 32 bends at the boundary (inflection point) between the right portion 322R and the right connecting portion 325R. Similarly, the left portion 322L moves rightward as the light-shielding wall 32 bends at the boundary (inflection point) between the left portion 322L and the left connecting portion 325L.

[0028] As described above, right connecting portion 325R connects upper portion 321 and right portion 322R such that as the contact pressure on right connecting portion 325R increases, right portion 322R approaches the user's face. Similarly, left connecting portion 325L connects upper portion 321 and left portion 322L such that as the contact pressure on left connecting portion 325L increases, left portion 322L approaches the user's face.

[0029] In the first embodiment, the right section 322R and the right connecting section 325R extend diagonally rearward to the right in a top view. The left section 322L and the left connecting section 325L extend diagonally rearward to the left in a top view. That is, the light-shielding wall 32 is substantially V-shaped in a top view. Because of this shape, the face of the HMD 1 user is more likely to come into contact with the light-shielding wall 32 compared to a configuration in which the right section 322R, the right connecting section 325R, the left section 322L, and the left connecting section 325L extend straight rearward. Therefore, it is possible to prevent a gap from being generated between the user's face and the light-shielding wall 32.

[0030] By adopting the configuration described above, even when a user with a small head wears the HMD 1, the right section 322R and the left section 322L move close to the user's face, thereby preventing external light from entering through gaps between the right section 322R and the left section 322L and the user's face. As a result, external light is prevented from entering the user's eyes.

[0031] Furthermore, when a user with a large head wears the HMD 1, the contact pressure applied to the user's face is alleviated because the light-shielding wall 32 includes bellows that expand and contract in response to contact pressure, thereby reducing discomfort caused by contact with the light-shielding wall 32.

[0032] Furthermore, the light-shielding member 30 includes, at its lower portion, a nose accommodating portion 35 for accommodating the nose of a user wearing the HMD 1. The nose accommodating portion 35 is integrally formed with the light-shielding wall 32 at the lower portion of the light-shielding wall 32. The nose accommodating portion 35 is preferably made of an elastic resin, similar to the light-shielding wall 32. The nose accommodating portion 35 has a shape that protrudes forward and is preferably provided so as to fit into a recess (not shown in the drawings illustrating the first embodiment; see FIG. 10 illustrating the second embodiment described below) formed at the lower portion of the housing 10a when the light-shielding member 30 is attached to the housing 10a. In this way, since the light-shielding member 30 includes the nose accommodating portion 35, discomfort caused by the nose of a user wearing the HMD 1 interfering with the light-shielding wall 32 can be reduced.

[0033] The nose accommodating section 35 is configured to include a front section 35F that forms the front portion of the nose accommodating section 35, a right section 35R that forms the right portion of the nose accommodating section 35, and a left section 35L that forms the left portion of the nose accommodating section 35, and is open below and behind. The nose of a user wearing the HMD 1 is positioned in a space R surrounded by the front section 35F, the right section 35R, and the left section 35L.

[0034] The right portion 35R includes a right portion 35R1 extending rearward from the front portion 35F and a first right light-shielding portion 35R2 extending leftward from the right portion 35R1 to reduce external light entering the user's eyes through the gap between the nose accommodation portion 35 and the user's nose. The left portion 35L includes a left portion 35L1 extending rearward from the front portion 35F and a first left light-shielding portion 35L2 extending rightward from the left portion 35L1 to reduce external light entering the user's eyes through the gap between the nose accommodation portion 35 and the user's nose. The first right light-shielding portion 35R2 and the first left light-shielding portion 35L2 may be sheet-shaped. In the first embodiment, as shown in FIG. 5 and other figures, the first right light-shielding portion 35R2 and the first left light-shielding portion 35L2 are spaced apart in the left-right direction, and a slit extending in the up-down direction is formed between them.

[0035] The nose of a user wearing the HMD 1 is accommodated in the space R via a slit formed between the first right light-shielding portion 35R2 and the first left light-shielding portion 35L2. In this way, since the nose accommodating portion 35 includes the first right light-shielding portion 35R2 and the first left light-shielding portion 35L2, it is possible to prevent external light from entering through the gap between the right portion 35R and the left portion 35L of the nose accommodating portion 35 and the user's nose. As a result, it is possible to prevent external light from entering the user's eyes.

[0036] Furthermore, the right portion 35R includes a second right light-shielding portion 35R3 extending leftward from the right portion 35R1 to reduce external light entering the user's eyes through the gap between the nose accommodation portion 35 and the user's nose, and positioned forward of the first right light-shielding portion 35R2. The left portion 35L includes a second left light-shielding portion 35L3 extending rightward from the left portion 35L1 to reduce external light entering the user's eyes through the gap between the nose accommodation portion 35 and the user's nose, and positioned forward of the first left light-shielding portion 35L2. The second right light-shielding portion 35R3 and the second left light-shielding portion 35L3 may be sheet-shaped. The second right light-shielding portion 35R3 and the second left light-shielding portion 35L3 are positioned to divide the space R into two spaces in the front-to-rear direction. The second right light-shielding portion 35R3 and the second left light-shielding portion 35L3 are spaced apart in the left-right direction, and a slit extending in the up-down direction is formed between them.

[0037] When a user with a high nose (having a nose that is long in the front-to-back direction) wears the HMD 1, the user's nose is accommodated in the space R via the slit formed between the first right light shielding portion 35R2 and the first left light shielding portion 35L2 and the slit formed between the second right light shielding portion 35R3 and the second left light shielding portion 35L3. This configuration can further prevent external light from entering through the gap between the right portion 35R and the left portion 35L of the nose accommodation portion 35 and the user's nose.

[0038] 4 and 5, the right portion 35R includes a right inclined portion that slopes downward toward the right and elastically contacts at least a part of the inner side of the right lens of the eyeglasses worn by the user. The right inclined portion is composed of a right inclined surface 35R2C that is the right edge of the first right light-shielding portion 35R2 and a portion of the right portion 35R1 that slopes along the right inclined surface 35R2C.

[0039] Similarly, the left section 35L includes a left inclined portion that slopes downward toward the left and elastically contacts at least a part of the inner edge of the left lens of the eyeglasses worn by the user. The left inclined portion is composed of a left inclined surface 35L2C that is the left edge of the first left light-shielding section 35L2 and a portion of the left section 35L1 that slopes along the left inclined surface 35L2C.

[0040] The HMD 1 according to the first embodiment described above can prevent external light from entering the user's eyes when used by a user with a small head, thereby improving the sense of immersion. On the other hand, when used by a user with a large head, it can prevent the user from feeling uncomfortable due to the contact pressure of the light blocking member 30.

[0041] Furthermore, because the nose accommodation portion 35 includes an inclined portion that elastically contacts at least a portion of the inner side of the lens rim of the eyeglasses, the position of the eyeglasses can be stabilized even when the user uses the HMD 1 while wearing the eyeglasses. That is, the eyeglasses can be prevented from shifting position in the front-to-back direction or tilting obliquely. As a result, scratches and dirt on the right lens 12R and left lens 12L of the HMD 1 due to contact between the lens rim of the eyeglasses and the right lens 12R and left lens 12L can be prevented.

[0042] The light-shielding member 30 shown in the first embodiment is merely an example, and it is sufficient that the light-shielding wall 32 at least partially includes a bellows that expands and contracts in response to contact pressure. The light-shielding wall 32 is not limited to one that includes a bellows, and it is sufficient that the light-shielding wall 32 elastically deforms at least in response to contact pressure.

[0043] [Second embodiment] Next, with reference to FIGS. 9 to 14, details of the light blocking member 230 of the second embodiment will be described. FIG. 9 is a rear view of a portion of a head-mounted display to which the light blocking member of the second embodiment is attached, as seen from behind. FIG. 10 is a perspective view of the head-mounted display to which the light blocking member of the second embodiment is attached, as seen obliquely from behind. FIG. 11 is a perspective view of the light blocking member of the second embodiment, as seen obliquely from below. FIG. 12 is an enlarged view illustrating details of the shape of the nose accommodation portion of the second embodiment. FIG. 13 is a rear view of a portion of a head-mounted display to which the light blocking member of the second embodiment is attached, and eyeglasses worn by a user, as seen from behind. FIG. 14 is a perspective view of the head-mounted display to which the light blocking member of the second embodiment is attached, and eyeglasses worn by a user, as seen obliquely from behind. Note that FIGS. 13 and 14 show eyeglasses G worn by the user, but the user himself is not shown.

[0044] In the second embodiment, a configuration is adopted that can further stabilize the posture of the glasses G even when the user uses the HMD 1 while wearing the glasses G. Note that the same reference numerals are used for components having the same functions as those described in the first embodiment, and detailed descriptions thereof will be omitted.

[0045] The light blocking member 230 is a member provided to block or reduce external light incident on the eyes of a user wearing the HMD 1. The light blocking member 230 is preferably made of an elastic resin. However, the light blocking member 230 is not limited to being made of resin, and may be made of, for example, a fibrous material (such as a sponge).

[0046] As shown in FIG. 11 , the light blocking member 230 includes an attachment portion 231 that is attached to the housing 10a of the device body 10. The attachment portion 231 is preferably annular and surrounds the right lens 12R and left lens 12L housed in the housing 10a when viewed from the rear. The attachment portion 231 is preferably configured to be detachable from the housing 10a. For example, as shown in FIG. 11 , a plurality of locking protrusions 231a are formed on the front portion of the attachment portion 231, and the locking protrusions 231a are preferably fitted into a plurality of grooves formed in the housing 10a, thereby enabling the light blocking member 230 to be attached to the housing 10a. However, the present invention is not limited to this, and the attachment portion 231 may be formed and fixed to the housing 10a by two-color molding or insert molding.

[0047] The light blocking member 230 also includes a light blocking wall 232 extending rearward from the mounting portion 231. The light blocking wall 232 extends rearward from the mounting portion 231 so as to come into contact with the periphery of the eyes of the user wearing the HMD 1. By including the light blocking wall 232, the light blocking member 230 exhibits the function of blocking or reducing external light incident on the eyes of the user wearing the HMD 1. It is preferable that the mounting portion 231 and the light blocking wall 232 are integral with each other.

[0048] In the second embodiment, an example will be described in which the light-shielding wall 232 does not have a bellows that expands and contracts in response to contact pressure, but the present invention is not limited to this and the light-shielding wall 232 may have a bellows. The light-shielding wall 232 is preferably made of at least an elastic material that elastically deforms in response to contact pressure.

[0049] The light-shielding member 230 includes, at its lower part, a nose accommodating section 235 that accommodates the nose of a user wearing the HMD 1. The nose accommodating section 235 is formed integrally with the light-shielding wall 232 at the lower part of the light-shielding wall 232. The nose accommodating section 235 is preferably made of an elastic resin, similar to the light-shielding wall 232.

[0050] 10 and 11, nose accommodating portion 235 has a shape that protrudes forward, and at least a portion of it is located forward of attachment portion 231. Housing 10a also includes recess 11a in which the portion of nose accommodating portion 35 located forward of attachment portion 231 is disposed. In this way, since housing 10a includes recess 11a, the width of nose accommodating portion 235 in the front-to-rear direction can be increased.

[0051] Since the light blocking member 230 includes the nose accommodation portion 235, discomfort caused by the nose of the user wearing the HMD 1 interfering with the light blocking wall 232 can be reduced.

[0052] The nose accommodating portion 235 is configured to include a front portion 235F that constitutes the front part of the nose accommodating portion 235, a right portion 235R that constitutes the right part of the nose accommodating portion 235, and a left portion 235L that constitutes the left part of the nose accommodating portion 235, and is open below and behind. The nose of a user wearing the HMD 1 is positioned in a space R surrounded by the front portion 235F, the right portion 235R, and the left portion 235L.

[0053] The right portion 235R includes a right side portion 235R1 extending rearward from the front portion 235F and a first right light-shielding portion 235R2 extending leftward from the right side portion 235R1 so as to reduce external light entering the user's eyes through a gap between the nose accommodating portion 235 and the user's nose. The left portion 235L includes a left side portion 235L1 extending rearward from the front portion 235F and a first left light-shielding portion 235L2 extending rightward from the left side portion 235L1 so as to reduce external light entering the user's eyes through a gap between the nose accommodating portion 235 and the user's nose. The first right light-shielding portion 235R2 and the first left light-shielding portion 235L2 may be sheet-shaped. In the first embodiment, as shown in FIG. 9, the first right light-shielding portion 235R2 and the first left light-shielding portion 235L2 are spaced apart in the left-right direction, and a slit extending in the up-down direction is formed between them.

[0054] The nose of a user wearing the HMD1 is accommodated in the space R via a slit formed between the first right light-shielding portion 235R2 and the first left light-shielding portion 235L2. In this way, since the nose accommodating portion 235 includes the first right light-shielding portion 235R2 and the first left light-shielding portion 235L2, it is possible to prevent external light from entering through gaps between the right portion 235R and the left portion 235L of the nose accommodating portion 235 and the user's nose. As a result, it is possible to prevent external light from entering the user's eyes.

[0055] Furthermore, the right portion 235R includes a second right light-shielding portion 235R3 extending leftward from the right portion 235R1 to reduce external light entering the user's eyes through the gap between the nose accommodating portion 235 and the user's nose, and disposed forward of the first right light-shielding portion 235R2. The left portion 235L includes a second left light-shielding portion 235L3 extending rightward from the left portion 235L1 to reduce external light entering the user's eyes through the gap between the nose accommodating portion 235 and the user's nose, and disposed forward of the first left light-shielding portion 235L2. The second right light-shielding portion 235R3 and the second left light-shielding portion 235L3 may be sheet-shaped. The second right light-shielding portion 235R3 and the second left light-shielding portion 235L3 are disposed so as to divide the space R into two spaces in the front-to-rear direction. The second right light-shielding portion 235R3 and the second left light-shielding portion 235L3 are spaced apart in the left-right direction, and a slit extending in the up-down direction is formed between them.

[0056] When a user with a high nose (having a nose that is long in the front-to-back direction) wears the HMD 1, the user's nose is accommodated in the space R via the slit formed between the first right light shielding portion 235R2 and the first left light shielding portion 235L2 and the slit formed between the second right light shielding portion 235R3 and the second left light shielding portion 235L3. With this configuration, it is possible to further prevent external light from entering through the gap between the right portion 235R and the left portion 235L of the nose accommodating portion 235 and the user's nose.

[0057] In commonly used eyeglasses, the inner and lower portions of the right lens rim are curved and connected, and the inner and lower portions of the left lens rim are curved and connected. In the nose accommodation portion 235 of the second embodiment, the right portion 235R and the left portion 235L are shaped to follow the shape of the lens rim of commonly used eyeglasses. Specifically, they have the following shapes.

[0058] 12 and 13, the right portion 235R is inclined downward toward the right and includes a right inclined portion that elastically contacts at least a part of the inner portion GR1 of the right lens edge GR of the eyeglasses G worn by the user. The right inclined portion is composed of a right inclined surface 235R2C that is the right edge of the first right light-shielding portion 235R2 and a portion of the right portion 235R1 that inclines so as to follow the right inclined surface 235R2C.

[0059] Similarly, left section 235 includes a left inclined portion that slopes downward toward the left and elastically contacts at least a part of the inner side GL1 of the left lens edge GL of the eyeglasses G worn by the user. The left inclined portion is composed of a left inclined surface 235L2C that is the left edge of first left light-shielding section 235L2, and a portion of left side section 235L1 that slopes along left inclined surface 235L2C.

[0060] Furthermore, as shown in Fig. 12, the right inclined surface 235R2C includes a first right inclined surface 235R2C1 and a second right inclined surface 235R2C2 that is located below the first right inclined surface 235R2C1 and has a gentler slope than the first right inclined surface 235R2C1. As shown in Fig. 12, the first right inclined surface 235R2C1 has a shape that is recessed to the left. Note that the shape of the right inclined surface 235R2C shown in Fig. 12 is an example and is not limited thereto, but it is preferable that at least the slope of the lower part of the right inclined surface 235R2C is gentle.

[0061] Similarly, the left inclined surface 235L2C includes a first left inclined surface 235L2C1 and a second left inclined surface 235L2C2 located below the first left inclined surface 235LC1 and having a gentler slope than the first left inclined surface 235L2C1. As shown in Fig. 12, the first left inclined surface 235L2C1 has a shape recessed to the right. Note that the shape of the left inclined surface 235L2C shown in Fig. 12 is an example and is not limited thereto, but it is preferable that at least the slope of the lower part of the left inclined surface 235L2C is gentle.

[0062] As described above, since the right portion 235R and the left portion 235L have the configuration shown in FIG. 12 and other figures, the inner portions of the lens rims of the eyeglasses G worn by the user are supported by the nose accommodation portion 235. Therefore, even when the user uses the HMD 1 while wearing the eyeglasses G, the posture of the eyeglasses G can be stabilized. In other words, it is possible to prevent the eyeglasses G from shifting in position in the front-to-back direction or tilting obliquely. As a result, it is possible to prevent the lens rims of the eyeglasses G and the like from coming into contact with the right lens 12R and the left lens 12L of the HMD 1, thereby preventing scratches and dirt from being formed on the right lens 12R and the left lens 12L.

[0063] 10, 14, etc., the baffle wall 232 includes a right contact portion 232R that elastically contacts at least a part of the right temple TR of the eyeglasses G worn by the user, and a left contact portion 232L that elastically contacts at least a part of the left temple TL. The right contact portion 232R includes the bottom surface of a right recess DR formed in the baffle wall 232, and the left contact portion 232L includes the bottom surface of a left recess DL formed in the baffle wall 232. The right recess DR and the left recess DL are provided in front of the ears of the user wearing the HMD 1, and have a predetermined width in the up-down direction.

[0064] When the user is wearing the eyeglasses G, the right temple TR fits into the right recess DR, and the left temple TL fits into the left recess DL. As a result, the inside of the eyeglasses G worn by the user elastically contacts the right inclined surface 235R2C and the left inclined surface 235L2C, and the outside of the eyeglasses G elastically contacts the right contact portion 232R and the left contact portion 232L. In this way, the eyeglasses G worn by the user are supported at four points by the light-blocking member 230, making their posture more stable.

[0065] Furthermore, in the second embodiment, as shown in Fig. 11, the first right light shielding portion 235R2 extends forward as it moves leftward, and the first left light shielding portion 235L2 extends forward as it moves rightward. Note that the first right light shielding portion 235R2 and the first left light shielding portion 235L2 may have an extending shape as shown in Fig. 11 regardless of the orientation of the light shielding member 230. In other words, the first right light shielding portion 235R2 and the first left light shielding portion 235L2 may have an extending shape as shown in Fig. 11 regardless of the direction in which gravity acts.

[0066] Since the first right light shielding portion 235R2 and the first left light shielding portion 235L2 are configured to extend forward in this manner, the first right light shielding portion 235R2 and the first left light shielding portion 235L2 are prevented from bending backward when the user wears the HMD 1. This prevents a gap from being formed between the user's nose and the nose accommodating portion 235. As a result, external light is prevented from entering the user's eyes. Furthermore, the contact pressure (repulsion force) of the first right light shielding portion 235R2 and the first left light shielding portion 235L2 on the user's nose is reduced, thereby preventing discomfort caused by contact between the first right light shielding portion 235R2 and the first left light shielding portion 235L2.

[0067] In the second embodiment, as shown in FIG. 12 and other figures, the upper edge E1 of the first right light-shielding portion 235R2 is inclined downward toward the right. Therefore, the angle formed by the upper edge E1 and the right inclined surface 235R2C is an obtuse angle. This prevents the corner formed by the upper edge E1 and the right inclined surface 235R2C from interfering with the right lens edge GR of the eyeglasses G, thereby preventing unintended deformation of the nose housing 235. As a result, it is possible to prevent a gap from being generated between the user's nose and the nose housing 235.

[0068] Similarly, the upper edge E2 of the first left light-shielding portion 235L2 is inclined downward toward the left. Therefore, the angle formed by the upper edge E2 and the left inclined surface 235L2C is an obtuse angle. This prevents the corner formed by the upper edge E2 and the left inclined surface 235L2C from interfering with the left lens edge GL of the eyeglasses G, thereby preventing unintended deformation of the nose housing portion 235. As a result, it is possible to prevent a gap from being formed between the user's nose and the nose housing portion 235. [Explanation of symbols]
