An exemplary embodiment of the present disclosure will be described below with reference to the drawings.
Schematic Configuration of Head-mounted Display Apparatus
The head-mounted display apparatus 1 according to the present exemplary embodiment is used to be mounted on a user's head, displays an image that can be visually recognized by the user, and is a so-called Head Mounted Display (HMD). As illustrated in
As described later in detail, the display unit 3 includes a left-side display unit 3L and a right-side display unit 3R each configured to display an image. The support portion 5 supports the display unit 3, the temples 4L and 4R, and the nose pad 6. The temples 4L and 4R are suspended on the user's left and right ears and the nose pad 6 abuts the user's nose such that the head-mounted display apparatus 1 is mounted on the user's head.
Hereinafter, a configuration of the head-mounted display apparatus 1 will be described in detail.
In the following description, three directions perpendicular to each other are referred as an +X direction, a +Y direction, and a +Z direction, and a direction from the rear surface to the front surface of the head-mounted display apparatus 1 is referred as the +Z direction. Further, a direction from right to left when the head-mounted display apparatus 1 is viewed from the +Z direction is referred as the +X direction, and a direction from bottom to top when the head-mounted display apparatus 1 is viewed from the +Z direction is referred as the +Y direction.
Also, although not illustrated, for convenience of description, opposite directions to the +X direction, the +Y direction, and the +Z direction are referred as a −X direction, a −Y direction, and a −Z direction, respectively. In addition, axes along the +X direction, the +Y direction, and the +Z direction are referred as an X axis, a Y axis, and a Z axis, respectively.
In the present exemplary embodiment, a first axis connecting nose rest portions 62L and 62R, which will be described later, is the X axis. Further, a first direction being a direction in which the display unit 3 described later emits image light to the outside is the −Z direction. The +Z direction being the opposite direction to the −Z direction is a mounting direction of the nose pad 6 with respect to the support portion 5.
Further, the axis on which a frame 53 constituting the support portion 5 extends is the X axis. A direction from the left-side display unit 3L supported by the frame 53 toward the right-side display unit 3R is the +X direction.
Then, the +Y direction is a direction that is orthogonal to each of the +Z direction and the +X direction, and directed from a front portion 531 of the frame 53 toward the left-side light guiding unit 32L and the right-side light guiding unit 32R. The −Y direction is a direction that intersects each of the +X direction parallel to the +X axis, which is the first axis connecting the nose rest portions 62L and 62R described later, and the +Z direction being an insertion direction of an insertion portion 61 of the nose pad 6 with respect to an attachment portion 54 described later, and that is directed from the insertion portion 61 toward the nose rest portions 62L and 62R.
Note that, for a user wearing the head-mounted display apparatus 1, the +X direction is a direction from left to right, the +Y direction is a direction from bottom to top, and the +Z direction is a direction from rear to front.
For this reason, of the configuration of the head-mounted display apparatus 1, “L” is appended to a sign of a configuration disposed on the left side to the user, that is, in the −X direction, and “R” is appended to a sign of a configuration located on the right side to the user, that is, in the +X direction.
Configuration of Display Unit
The display unit 3 emits image light toward a predetermined visual recognition position to display an image formed by the image light. The predetermined visual recognition position is a position of an exit pupil formed by an optical system constituting the display unit 3. In the present exemplary embodiment, the predetermined visual recognition positions are set to a virtual position corresponding to the left eye and the right eye of the user. Then, the display unit 3 includes the left-side display unit 3L configured to emit left eye image light to the left eye of the user, which is one of the visual recognition positions, to display a left eye image, and the right-side display unit 3R configured to emit right eye image light to the right eye of the user, which is another one of the visual recognition positions, to display a right eye image.
Configuration of Left-side Display Unit
The left-side display unit 3L is located in the −X direction in the apparatus main body 2. The left-side display unit 3L includes a left-side emitting unit 31L as an image emitting unit configured to form and emit left eye image light, and the left-side light guiding unit 32L as a light guiding unit configured to guide the emitted left eye image light to the left eye of the user.
The left-side emitting unit 31L is housed in a left-side housing 52L, which will be described later, and forms and emits left eye image light according to image information input from the outside. The left-side emitting unit 31L includes a control unit, an image forming unit, and an image projection unit, which are not illustrated in the drawings.
The control unit outputs an image signal according to the input image information to the image forming unit, and causes the image forming unit to form the left eye image light according to the image information. The control unit is a circuit board on which a circuit element is mounted.
The image forming unit forms the left eye image light according to the image signal input from the control unit. The image forming unit can be constituted by a self-emitting display panel such as an organic Electro-Luminescence (EL) panel, and can also be constituted by a combination of a light source such as an LED and a light modulation device such as a device using a micromirror such as a liquid crystal panel and a MEMS mirror.
The image projection unit is constituted by a lens or a prism, and the image light formed by the image forming unit is projected in the +Z direction.
The left-side light guiding unit 32L is supported by the frame 53, which will be described later, of the support portion 5, and is disposed along the X axis in a position corresponding to the left eye of the user at a position in the +Z direction with respect to the left-side emitting unit 31L. The left-side light guiding unit 32L guides the left eye image light emitted from the left-side emitting unit 31L into the +X direction while internally reflecting the left eye image light at an interface, and emits the left eye image light in the −Z direction toward the left eye by a semi-transparent layer provided to correspond to an eyeball of the user's left eye. In other words, the left-side display unit 3L emits the left eye image light from the left-side light guiding unit 32L in the −Z direction.
The left-side light guiding unit 32L is made of a resin such as a cycloolefin polymer having high translucency in a visible light region, for example, and the user can observe an external scene via the left-side light guiding unit 32L.
Configuration of Right-Side Display Unit
The right-side display unit 3R is located in the +X direction in the apparatus main body 2. The right-side display unit 3R includes a right-side emitting unit 31R as an image emitting unit configured to form and emit right eye image light, and the right-side light guiding unit 32R as a light guiding unit configured to guide the emitted right eye image light to the right eye of the user.
The right-side emitting unit 31R is housed in a right-side housing 52R, which will be described later, and forms and emits right eye image light according to image information input from the outside. Similarly to the left-side emitting unit 31L, the right-side emitting unit 31R includes a control unit, an image forming unit, and an image projection unit.
The right-side light guiding unit 32R is supported by the frame 53 and is disposed along the X axis in a position corresponding to the right eye of the user at a position in the +Z direction with respect to the right-side emitting unit 31R. The right-side light guiding unit 32R guides the right eye image light emitted in the +Z direction from the right-side emitting unit 31R into the −X direction while internally reflecting the right eye image light at an interface, and emits the right eye image light in the −Z direction toward the right eye by a semi-transparent layer provided to correspond to an eyeball of the user's right eye. In other words, the right-side display unit 3R emits the right eye image light that forms a right eye image from the right-side light guiding unit 32R in the −Z direction. The right-side light guiding unit 32R is constituted by a material having translucency similar to that of the left-side light guiding unit 32L, for example, and the user can observe an external scene via the right-side light guiding unit 32R.
In this way, the head-mounted display apparatus 1 is configured as a see-through type head-mounted display apparatus that allows a user to observe an image and an external scene at the same time via the left-side light guiding unit 32L and the right-side light guiding unit 32R.

If a user observes an external scene via the left-side light guiding unit 32L and the right-side light guiding unit 32R, the user's line of sight passes through the left-side opening 512L and the right-side opening 512R.
The fixing portion 515L is provided at an end portion in the −X direction of the main body 511. The fixing portion 515L includes an upper arm portion 5151 that extends in the −Z direction from an end edge in the +Y direction of the main body 511, and a lower arm portion 5153 that extends in the −Z direction from an end edge in the −Y direction of the main body 511.
The fixing portion 515R is provided at an end portion in the +X direction of the main body 511. Similarly to the fixing portion 515L, the fixing portion 515R includes an upper arm portion 5151 and a lower arm portion 5153.
Then, the upper arm portion 5151 and the lower arm portion 5153 of the fixing portion 515L are fixed to the left-side housing 52L, and the upper arm portion 5151 and the lower arm portion 5153 of the fixing portion 515R are fixed to the right-side housing 52R, and thus the mounting member 51 is fixed to the left-side housing 52L and the right-side housing 52R.
Configuration of Left-Side Housing
The left-side housing 52L is a housing made of a synthetic resin, is attached to an end portion in the −X direction of the frame 53, and houses the left-side emitting unit 31L. The left-side housing 52L includes a shaft support portion 52L2 at a portion in the +Z direction of a side surface 52L1 in the +X direction.
The shaft support portion 52L2 is a portion to which the fixing portion 515L is fixed in addition to rotatably supporting the temple 4L.

The right-side housing 52R includes a shaft support portion 52R2 at a portion in the +Z direction of a side surface 52R1 in the −X direction.
The shaft support portion 52R2 is a portion to which the fixing portion 515R is fixed in addition to rotatably supporting the temple 4R.
Configuration of Frame
The frame 53 is a substantially U-shaped metal member when viewed from the +Y direction, and is disposed along the X axis. In other words, a first end of the frame 53 is located in the −X direction, and a second end is located in the +X direction. As illustrated in
The front portion 531 is a portion of the frame 53 along an XZ plane. The front portion 531 supports the left-side light guiding unit 32L and the right-side light guiding unit 32R by being attached with the attachment portion 54 from the −Y direction so as to sandwich the left-side light guiding unit 32L and the right-side light guiding unit 32R between a surface 532 in the −Y direction and the attachment portion 54. In other words, the attachment portion 54 is an attachment member that is attached to the surface 532 so as to be located between the left-side light guiding unit 32L and the right-side light guiding unit 32R, and supports the nose pad 6 in addition to supporting the left-side light guiding unit 32L and the right-side light guiding unit 32R together with the frame 53.
The configuration of such an attachment portion 54 will be described later in detail.
Configuration of Nose Pad
The nose pad 6 is attached so as to be insertable into the attachment portion 54, and is rotatably supported in the +Y direction and the −Y direction when viewed from the −Z direction by the attachment portion 54. In other words, the nose pad 6 is provided so as to be replaceable with respect to the apparatus main body 2.
As illustrated in
Such a nose pad 6 includes the insertion portion 61, the nose rest portions 62L and 62R, rocking support portions 63L and 63R, and connecting portions 64L and 64R.
Configuration of Insertion Portion
The insertion portion 61 is a portion of the nose pad 6 that is inserted into the attachment portion 54 along the +Z direction, and is located in the +Z direction at a position in the +Y direction in the nose pad 6. The insertion portion 61 includes a shaft portion 611, first extending portions 612L and 612R and second extending portions 613L and 613R that are located on the same plane.
The shaft portion 611 is located at a tip portion in the +Z direction of the insertion portion 61, and is a cylindrical portion along the X axis. A shaft direction of the shaft portion 611 coincides with the rotational movement shaft of the nose pad 6 when the insertion portion 61 is inserted into and supported by an insertion opening 541, which will be described later, of the attachment portion 54.
The first extending portion 612L extends in the −Z direction from an end portion in the −X direction of the shaft portion 611, and the first extending portion 612R extends in the −Z direction from an end portion in the +X direction of the shaft portion 611. A part of the first extending portions 612L and 612R is inserted into the insertion opening 541 together with the shaft portion 611.
The second extending portions 613L and 613R respectively extend in directions, that are away from each other, from end portions of the first extending portions 612L and 612R opposite to the shaft portion 611. More specifically, the second extending portion 613L located in the −X direction extends in the −X direction from an end portion of the first extending portion 612L opposite to the shaft portion 611. The second extending portion 613R located in the +X direction extends in the +X direction from an end portion of the first extending portion 612R opposite to the shaft portion 611.
Such second extending portions 613L and 613R are portions that are locked by first locking portions 543L and 543R and second locking portions 544L and 544R, which will be described later, of the attachment portion 54.
The second extending portions 613L and 613R have rigidity that can be bent in a direction closer to and away from each other in the X axis. In other words, the second extending portions 613L and 613R have flexibility in a direction closer to and away from each other in the X axis. Thus, when the connecting portions 64L and 64R described later are displaced in a direction closer to each other, the second extending portions 613L and 613R are bent in a direction closer to each other. In this way, a locking position of the nose pad 6 in the attachment portion 54 can be changed, which will be described later in detail.
As illustrated in
Note that, in the present exemplary embodiment, the intersection angle αL and the intersection angle αR are the same angle, but may be different from each other, and only one intersection angle of the intersection angles αL and αR may be an obtuse angle, and the other intersection angle may be an angle other than an obtuse angle, such as a right angle, for example.
Configuration of Nose Rest Portion and Rocking Support Portion
When the head-mounted display apparatus 1 is mounted on the user's head, the nose rest portion 62L abuts a portion on the left side of the user's nose, and the nose rest portion 62R abuts a portion on the right side of the user's nose. One nose rest portion of the nose rest portions 62L and 62R corresponds to a first nose rest portion, and the other nose rest portion corresponds to a second nose rest portion.
Here, a shape of the nose that the nose rest portions 62L and 62R abut differs from user to user. For this reason, the nose rest portions 62L and 62R are rockingly supported by the rocking support portions 63L and 63R provided in a position in the −Z direction at a position in the −Y direction of the nose pad 6 so as to appropriately abut the nose.
More specifically, the nose rest portion 62L includes an abutment portion 62L1 that abuts a portion on the left side of the user's nose, and is rockingly supported by the rocking support portion 63L located in the −X direction such that the abutment portion 62L1 faces in the +X direction at a position in the −Y direction. Similarly, the nose rest portion 62R includes an abutment portion 62R1 that abuts a portion on the right side of the user's nose, and is rockingly supported by the rocking support portion 63R located in the +X direction such that the abutment portion 62R1 faces in the −X direction at a position in the −Y direction.
One rocking support portion of the rocking support portions 63L and 63R is a first rocking support portion that rockingly supports the nose rest portion corresponding to the first nose rest portion of the nose rest portions 62L and 62R, and the other rocking support portion is a second rocking support portion that rockingly supports the nose rest portion corresponding to the second nose rest portion of the nose rest portions 62L and 62R.
Configuration of Connecting Portion
The connecting portion 64L is located in the −X direction, and couples the second extending portion 613L of the insertion portion 61 and the rocking support portion 63L. The connecting portion 64R is located in the +X direction, and couples the second extending portion 613R of the insertion portion 61 and the rocking support portion 63R. In other words, one connecting portion of the connecting portions 64L and 64R is a first connecting portion coupled to the rocking support portion corresponding to the first rocking support portion of the rocking support portions 63L and 63R, and the other connecting portion corresponds to a second connecting portion coupled to the rocking support portion corresponding to the second rocking support portion of the rocking support portions 63L and 63R.
As illustrated in
The first component 64R1 extends from an end portion of the second extending portion 613R opposite to the first extending portion 612R in the −Z direction being a direction away from the insertion portion 61.
The second component 64R2 extends in the −Y direction from the first component 64R1. In other words, the second component 64R2 extends from the first component 64R1 in the −Y direction that intersects each of the +X direction parallel to the X axis, which the first axis connecting the nose rest portions 62L and 62R, and the +Z direction being the insertion direction of the insertion portion 61 with respect to the attachment portion 54, and that is directed from the insertion portion 61 toward the nose rest portion 62R coupled to the connecting portion 64R of the nose rest portions 62L and 62R.
The third component 64R3 is bent with respect to the second component 64R2 along the −Y direction being the extending direction of the second component and in the −Z direction being the direction away from the insertion portion 61.
The fourth component 64R4 extends in the +X direction at a position in the −Y direction from the third component 64R3, and is coupled to the rocking support portion 63R coupled to the connecting portion 64R of the rocking support portions 63L and 63R.
As illustrated in
The first component 64L1 extends in the −Z direction from an end portion of the second extending portion 613L opposite to the first extending portion 612L.
The second component 64L2 extends in the −Y direction from the first component 64L1.
The third component 64L3 is bent with respect to the second component 64L2 in the −Z direction at a position in the −Y direction.
The fourth component 64L4 extends in the −X direction at a position in the −Y direction from the third component 64L3, and is coupled to the rocking support portion 63L.
Insertion Direction of Nose Pad with Respect to Attachment Portion
The nose pad 6 is attached to the attachment portion 54 provided between the left-side light guiding unit 32L and the right-side light guiding unit 32R in the frame 53. At this time, as illustrated in
Configuration of Attachment Portion
As illustrated in
Configuration of Insertion Opening and Rotation Support Portion
The insertion opening 541 is formed in a substantially H shape when viewed from the −Z direction. The insertion portion 61 is inserted into the insertion opening 541.
As illustrated in
More specifically, the rotation support portion 542 includes a first abutment surface 5421 having an arc shape that abuts a portion of the shaft portion 611 in the −Y direction at a position in the +Z direction, and a second abutment surface 5422 having an arc shape that abuts a portion of the shaft portion 611 in the +Y direction at a position in the −Z direction, and a gap GP is formed between the first abutment surface 5421 and the second abutment surface 5422.
Then, as illustrated in
Configuration of First Locking Portion
As illustrated in
Specifically, the first locking portion 543L extends in the −X direction from an inner end edge in the −Y direction of the insertion opening 541, and the first locking portion 543R extends in the +X direction from an inner end edge in the −Y direction of the insertion opening 541. When the insertion portion 61 is inserted into the insertion opening 541, the first locking portion 543L is a recessed portion into which the second extending portion 613L can fit, and the first locking portion 543R is a recessed portion into which the second extending portion 613R can fit. In other words, the first locking portions 543L and 543R are a recessed portion being recessed in the +Z direction.
Note that, as described above, the insertion portion 61 is inserted into the insertion opening 541 along the +Z direction, and thus when the nose pad 6 is attached to the attachment portion 54, the first locking portions 543L and 543R easily lock the second extending portions 613L and 613R.
As illustrated in
Such a first position is a position where the nose pad 6 is disposed such that the nose rest portions 62L and 62R of the nose pad 6 abut a portion in the −Y direction with respect to a portion where nose rest portions of eyeglasses abut a nose of a user wearing the eyeglasses, for example.
Note that, as described above, the connecting portions 64L and 64R of the nose pad 6 are configured such that the fourth components 64L4 and 64R4 are coupled to the rocking support portions 63L and 63R via the second components 64L2 and 64R2 extending in the −Y direction from the first components 64L1 and 64R1 coupled to the second extending portions 613L and 613R, and the third components 64L3 and 64R3 bent in the −Z direction at a position in the −Y direction from the second components 64L2 and 64R2. In other words, the connecting portions 64L and 64R extend in the −Y direction from the second extending portions 613L and 613R and then extend in the −Z direction and are coupled to the rocking support portions 63L and 63R, instead of extending in the −Z direction being a face side of a user from the second extending portions 613L and 613R and then extend in the −Y direction and are coupled to the rocking support portions 63L and 63R. More specifically, the connecting portions 64L and 64R extend slightly in the −Z direction from the second extending portions 613L and 613R and extend in the −Y direction, and then extend in the −Z direction and are coupled to the rocking support portions 63L and 63R, instead of extending in the −Z direction from the second extending portions 613L and 613R to corresponding positions in the +Y direction of the rocking support portions 63L and 63R and then extending downward to the rocking support portions 63L and 63R.
In this way, when the nose pad 6 is disposed in the first position, the nose rest portions 62L and 62R can more easily contact the portion in the −Y direction with respect to the portion where the nose rest portions of the eyeglasses abut the nose of the user wearing the eyeglasses. In other words, the nose rest portions 62L and 62R can abut the nose of the user such that the nose rest portions 62L and 62R and the connecting portions 64L and 64R do not interfere with the frame and the nose rest of the eyeglasses.
Configuration of Second Locking Portion
As illustrated in
Specifically, the second locking portion 544L extends in the −X direction from an inner end edge in the +Y direction of the insertion opening 541, and the second locking portion 544R extends in the +X direction from an inner end edge in the +Y direction of the insertion opening 541. Similarly to the first locking portions 543L and 543R, the second locking portions 544L and 544R are a recessed portion being recessed in the +Z direction. When the insertion portion 61 is inserted into the insertion opening 541, the second extending portion 613L can fit into the second locking portion 544L, and the second extending portion 613R can fit into the second locking portion 544R.
In this way, while the second extending portions 613L and 613R are locked by the second locking portions 544L and 544R, the nose pad 6 is disposed in a second position being a position in the +Y direction in a rotational range of the nose pad 6.
As illustrated in
Such a second position is, for example, a position where the nose pad 6 is disposed such that the nose rest portions 62L and 62R of the nose pad 6 abut a portion of a user's nose near eyebrows when the head-mounted display apparatus 1 is mounted on a head of a user who is not wearing eyeglasses. The nose pad 6 is then disposed in the second position, and thus the head-mounted display apparatus 1 can be stably mounted on the head of the user who is not wearing the eyeglasses.
Note that when the nose rest portions 62L and 62R abut the nose of the user, force in the +Z direction is applied to the nose rest portions 62L and 62R, and the connecting portions 64L and 64R displace in a direction away from each other. Thus, a connecting portion of the second extending portion 613L with the connecting portion 64L and a connecting portion of the second extending portion 613R with the connecting portion 64R are pressed against the first locking portions 543L and 543R or the second locking portions 544L and 544R. In other words, the opposite end portions of the second extending portions 613L and 613R are pressed against the first locking portion 543L and 543R and the second locking portions 544L and 544R.
In this way, when the head-mounted display apparatus 1 is mounted, detachment of the second extending portions 613L and 613R from the first locking portions 543L and 543R or the second locking portions 544L and 544R is suppressed, and thus a position shift of the nose pad 6 is suppressed.
Configuration of Regulating Portion
As illustrated in
The regulating portions 545L and 545R regulate unintended rotation of the nose pad 6 in the ±D direction when the head-mounted display apparatus 1 is mounted. In other words, the regulating portions 545L and 545R suppress rotation of the nose pad 6 disposed in the first position in the +D direction by abutting the second extending portions 613L and 613R, thereby suppressing an unintended change in the position of the nose pad 6 to the second position. Similarly, the regulating portions 545L and 545R suppress rotation of the nose pad 6 disposed in the second position in the −D direction by abutting the second extending portions 613L and 613R, thereby suppressing an unintended change in the position of the nose pad 6 to the first position.
On the other hand, the second extending portions 613L and 613R are displaced in a direction closer to each other such that the intersection angle αL between the first extending portion 612L and the second extending portion 613L is increased, and the intersection angle αR between the first extending portion 612R and the second extending portion 613R is also increased. Thus, the nose pad 6 can be rotated in the ±D direction while avoiding the regulating portions 545L and 545R. At this time, since the intersection angles αL and αR are each an obtuse angle, the second extending portions 613L and 613R can be easily displaced with respect to the first extending portions 612L and 612R. Therefore, an intended position change of the nose pad 6 can be easily performed.
Effects of Exemplary Embodiment
The head-mounted display apparatus 1 according to the present exemplary embodiment described above can obtain the following advantages.
The head-mounted display apparatus 1 includes the display unit 3 configured to emit image light to display an image, the support portion 5 that supports the display unit 3, and the nose pad 6 attached to the support portion 5. The support portion 5 includes the attachment portion 54 to which the nose pad 6 is attached. The nose pad 6 includes the insertion portion 61 inserted into the attachment portion 54. The attachment portion 54 includes the insertion opening 541 into which the insertion portion 61 is inserted, and the first locking portions 543L and 543R and the second locking portions 544L and 544R serving as locking portions each capable of locking the nose pad 6 in the first position and the second position that are different from each other in the rotational range of the nose pad 6 centered at the insertion portion 61 inserted into the insertion opening 541.
Accordingly, the nose pad 6 is rotated in the ±D direction as necessary while the insertion portion 61 is inserted into the insertion opening 541 provided in the attachment portion 54, and thus the second extending portions 613L and 613R are locked by the first locking portions 543L and 543R and the second locking portions 544L and 544R, thereby locking the nose pad 6 in the first position or the second position. Thus, the configuration of the attachment portion 54 that movably holds the nose pad 6 can be simplified compared to a case where an attachment portion has a structure that holds a nose pad to be slidable vertically, such as by providing a latch member. Therefore, the configuration of the head-mounted display apparatus 1 capable of adjusting a position of the nose pad 6 can be simplified, and the head-mounted display apparatus 1 can be easily assembled.
The nose pad 6 includes the nose rest portions 62L and 62R as a first nose rest portion and a second nose rest portion. The rotational direction of the nose pad 6 attached to the attachment portion 54 is the ±Y direction intersecting the X axis being the first axis that connects the nose rest portion 62L and the nose rest portion 62R when viewed from the −Z direction being the first direction in which the display unit 3 emits image light. Then, the attachment portion 54 includes, as locking portions, the first locking portions 543L and 543R configured to lock the nose pad 6 in the first position, and the second locking portions 544L and 544R configured to lock the nose pad 6 in the second position.
In this way, when viewed from the −Z direction, the nose pad 6 can be disposed in the first position or the second position being a position different in the ±Y direction being the vertical direction for the user wearing the head-mounted display apparatus 1. In this way, a position of the nose pad 6, that is, a position of the nose rest portions 62L and 62R can be adjusted depending on the size of a nose of the user, whether the user is wearing eyeglasses, or the like. Therefore, the mountability of the head-mounted display apparatus 1 can be increased.
The attachment portion 54 includes the rotation support portion 542 that is located inside the insertion opening 541, is configured to engage with the shaft portion 611 being the tip portion of the insertion portion 61 in the +Z direction, which is the insertion direction into the insertion opening 541, and rotatably supports the nose pad 6 about the shaft portion 611.
In this way, the rotation support portion 542 rotatably supports the nose pad 6 about the shaft portion 611 by engaging with the shaft portion 611 along the X axis. Thus, compared to a case where, for example, the rotation support portion 542 rotatably supports a center portion of the insertion portion 61 in the +Z direction, the dimension of the attachment portion 54 in the Y axis can be reduced. Therefore, an increase in size of the attachment portion 54 can be suppressed, and thus an increase in size of the head-mounted display apparatus 1 can be suppressed.
The insertion portion 61 includes the shaft portion 611 that extends along the X axis when viewed from the +Z direction being the first direction, and is rotatably supported by the rotation support portion 542, the two first extending portions 612L and 612R extending in the −Z direction from the end portions of the shaft portion 611 in the −X direction and the +X direction, and the two second extending portions 613L and 613R extending in the direction away from each other from the two first extending portions 612L and 612R opposite to the shaft portion 611. The second extending portions 613L and 613R are locked by one of the first locking portions 543L and 543R and the second locking portions 544L and 544R.
In this way, the nose pad 6 can be easily rotated in the ±D direction about the shaft portion 611, and thus a position of the nose rest portions 62L and 62R can be easily changed in the ±Y direction. Further, the second extending portions 613L and 613R extending from the first extending portions 612L and 612R in the direction away from each other are locked by the first locking portions 543L and 543R, and thus the nose pad 6 can be stably locked in the first position. The second extending portions 613L and 613R are locked by the second locking portions 544L and 544R, and thus the nose pad 6 can be stably locked in the second position. Therefore, a position shift of the nose pad 6 can be suppressed.
The first locking portions 543L and 543R and the second locking portions 544L and 544R are recessed portions into which the two second extending portions 613L and 613R fit.
In this way, the configuration of the first locking portions 543L and 543R configured to lock the nose pad 6 in the first position and the configuration of the second locking portions 544L and 544R configured to lock the nose pad 6 in the second position can be simplified. Therefore, the configuration of the attachment portion 54, and thus the configuration of the head-mounted display apparatus 1 can be simplified.
The attachment portion 54 includes the regulating portion 545L that is located between the first locking portion 543L and the second locking portion 544L, and is configured to abut the second extending portion 613L, and to regulate rotation of the nose pad 6 in the ±D direction. Further, the attachment portion 54 includes the regulating portion 545R that is located between the first locking portion 543R and the second locking portion 544R, and is configured to abut the second extending portion 613R to regulate rotation of the nose pad 6 in the ±D direction.
In this way, disposing the nose pad 6 in a position other than the first position and the second position can be suppressed, and the unintended rotation of the nose pad 6 can also be regulated. Therefore, a position shift of the nose pad 6 can be effectively suppressed.
The second extending portions 613L and 613R have flexibility that can bring the second extending portions 613L and 613R to be closer to and away from each other.
In this way, the nose pad 6 can be rotated by bending the second extending portions 613L and 613R in the direction closer to each other, and a position of the nose pad 6 can be changed. Then, the second extending portions 613L and 613R can be locked by the first locking portions 543L and 543R or the second locking portions 544L and 544R by expanding the second extending portions 613L and 613R in the direction away from each other from the state where the second extending portions 613L and 613R are bent in the direction closer to each other. Therefore, a position of the nose pad 6 can be easily adjusted.
The nose pad 6 includes the nose rest portions 62L and 62R, the rocking support portions 63L and 63R that rockingly support the nose rest portions 62L and 62R, and the connecting portions 64L and 64R that couple the insertion portion 61 and the rocking support portions 63L and 63R. The connecting portions 64L and 64R include the first components 64L1 and 64R1, the second components 64L2 and 64R2, the third components 64L3 and 64R3, and the fourth components 64L4 and 64R4, respectively. The first components 64L1 and 64R1 extend in the −Z direction being a direction away from the insertion portion 61. The second components 64L2 and 64R2 extend from the first components 64L1 and 64R1 in the −Y direction that intersects each of the +X direction parallel to the X axis connecting the nose rest portions 62L and 62R and the +Z direction being the insertion direction of the insertion portion 61 with respect to the attachment portion 54, and that is directed from the insertion portion 61 toward the nose rest portions 62L and 62R. The third components 64L3 and 64R3 are bent with respect to the second components 64L2 and 64R2 in a direction along the extending direction of the second components 64L2 and 64R2 and away from the insertion portion 61, namely, in the −Z direction at a position in the −Y direction. The fourth components 64L4 and 64R4 extend from the third components 64L3 and 64R3 and are coupled to the corresponding rocking support portions 63L and 63R.
In this way, for example, when the head-mounted display apparatus 1 is mounted on a head of a user wearing eyeglasses, interference of the nose pad 6 with the eyeglasses can be suppressed compared to a case where a second component constituting a connecting portion extends in the −Z direction, and a third component then extends in the −Y direction and is coupled to a rocking support portion. Therefore, the nose rest portions 62L and 62R can abut the nose of the user while avoiding bridges and nose rest portions of the eyeglasses, and the mountability of the head-mounted display apparatus 1 can be increased.
The display unit 3 includes the left-side light guiding unit 32L configured to guide the left eye image and the right-side light guiding unit 32R configured to guide the right eye image. The support portion 5 includes the frame 53 that supports the left-side light guiding unit 32L and the right-side light guiding unit 32R. The attachment portion 54 is located between the left-side light guiding unit 32L and the right-side light guiding unit 32R, and attaches the left-side light guiding unit 32L and the right-side light guiding unit 32R to the frame 53.
In this way, the attachment portion 54 can be used as a member that supports the nose pad 6 and as a member that attaches the left-side light guiding unit 32L and the right-side light guiding unit 32R to the frame 53. Thus, there is no need to separately provide a member that attaches the left-side light guiding unit 32L and the right-side light guiding unit 32R to the frame 53, in addition to the attachment portion 54 that supports the nose pad 6. Therefore, an increase in the number of parts of the support portion 5, and thus an increase in the number of parts of the head-mounted display apparatus 1 can be suppressed.
Further, since the attachment portion 54 is disposed between the left-side light guiding unit 32L and the right-side light guiding unit 32R, the nose pad 6 supported by the attachment portion 54 can easily abut the nose of the user wearing the head-mounted display apparatus 1. Therefore, the mountability of the head-mounted display apparatus 1 can be further increased.
Modification of Exemplary Embodiment
The present disclosure is not limited to the exemplary embodiment described above, and variations, modifications, and the like within the scope in which the object of the present disclosure can be achieved are included in the present disclosure.
In the above-described exemplary embodiment, the nose pad 6 is rotatably supported by the attachment portion 54 about the rotational movement shaft along the X axis. However, the exemplary embodiment is not limited thereto, and a nose pad may be configured to be rotatably supported by an attachment portion about a rotational movement shaft along the Y axis, for example. In other words, the rotational movement shaft of the nose pad is not limited to the rotational movement shaft along the X axis.
In the above-described exemplary embodiment, the nose pad 6 is locked, by the attachment portion 54, in the first position and the second position that are positions different from each other in the rotational direction of the nose pad 6, and the attachment portion 54 includes the first locking portions 543L and 543R configured to lock the nose pad 6 in the first position, and the second locking portions 544L and 544R configured to lock the nose pad 6 in the second position. However, the exemplary embodiment is not limited to this, and an attachment portion may include a locking portion capable of locking a nose pad in a third position different from the first position and the second position in a rotational direction of the nose pad. In other words, the number of locking portions included in the attachment portion may be three or more.
In the above-described exemplary embodiment, when the insertion portion 61 of the nose pad 6 is inserted into the insertion opening 541 of the attachment portion 54 along the +Z direction, the second extending portions 613L and 613R are locked by the first locking portions 543L and 543R. In other words, when the insertion portion 61 is inserted into the insertion opening 541, the second extending portions 613L and 613R are locked by the first locking portions 543L and 543R located in the −Y direction with respect to the second locking portions 544L and 544R. However, the exemplary embodiment is not limited to this. For example, when the second locking portions 544L and 544R are provided in the −Y direction with respect to the first locking portions 543L and 543R, and the like, a locking portion configured to lock the nose pad 6 when the insertion portion 61 is inserted into the insertion opening 541 may not necessarily need to be a locking portion in the −Y direction.
In the above-described exemplary embodiment, the first locking portions 543L and 543R configured to lock the nose pad 6 in the first position lock the second extending portions 613L and 613R, and the second locking portions 544L and 544R configured to lock the nose pad 6 in the second position lock the second extending portions 613L and 613R. However, the exemplary embodiment is not limited to this, and a portion of a nose pad locked by a first locking portion and a second locking portion as locking portions is not limited to the second extending portions 613L and 613R. For example, a locking portion may be configured to lock the first extending portions 612L and 612R.
Further, the attachment portion 54 may be configured to include one first locking portion of the first locking portions 543L and 543R, or may be configured to include one second locking portion of the second locking portions 544L and 544R.
In the above-described exemplary embodiment, in the rotational range of the nose pad 6, the position of the nose pad 6 in which the extending direction of the first extending portions 612L and 612R is along the −Z direction is the first position, and the position of the nose pad 6 in which the extending direction of the first extending portions 612L and 612R is inclined in the +Y direction is the second position. However, the exemplary embodiment is not limited to this, and the first position and the second position can be appropriately changed. For example, a position of a nose pad in which an extending direction of a first extending portion is inclined in the −Y direction may be a first position, and a position of the nose pad in which an extending direction of the first extending portion is inclined in the +Y direction may be a second position.
In the above-described exemplary embodiment, the attachment portion 54 includes the rotation support portion 542 that rotatably supports the shaft portion 611 being the tip portion of the insertion portion 61. However, the exemplary embodiment is not limited to this, and a portion supported by the attachment portion 54 as the rotational movement shaft of the nose pad 6 is not limited to the end portion in the +Z direction of the insertion portion 61. For example, the first extending portions 612L and 612R may be each provided with a shaft portion along the X axis, and a rotation support portion may be configured to rotatably support each of the shaft portions.
Further, the shaft portion 611 may not necessarily be cylindrical, and a tip portion of the insertion portion 61 that abuts the rotation support portion may be formed in an arc shape in the rotational range of the nose pad 6.
In the above-described exemplary embodiment, the nose pad 6 includes, as the first nose rest portion and the second nose rest portion, the nose rest portion 62L that abuts the portion on the left side of the user's nose, and the nose rest portion 62R that abuts the portion on the right side of the user's nose. Here, the first nose rest portion and the second nose rest portion may be integrated. In other words, the nose pad 6 may include, instead of the nose rest portions 62L and 62R, a nose rest portion that covers a part of the user's nose on the front surface side and abuts each of portions on the left and right sides of the user's nose. In this case, of the integrated nose rest portion, a portion that abuts the portion on the left side of the user's nose corresponds to a left-side nose rest portion, and a portion that abuts the portion on the right side of the user's nose corresponds to a right-side nose rest portion. Then, one of the left-side nose rest portion and the right-side nose rest portion corresponds to a first nose rest portion, and the other corresponds to a second nose rest portion.
In the above-described exemplary embodiment, the nose pad 6 includes the nose rest portions 62L and 62R. Here, the nose pad 6 may include three or more nose rest portions. For example, the nose pad 6 may include a nose rest portion that abuts a root or a line of the user's nose in addition to the nose rest portions 62L and 62R. In this case, of the plurality of nose rest portions, a nose rest portion that abuts a portion on the left side of the user's nose may be defined as the nose rest portion 62L, and a nose rest portion that abuts a portion on the right side of the user's nose may be defined as the nose rest portion 62R. In this case, of the nose rest portion that abuts the portion on the left side of the user's nose and the nose rest portion that abuts the portion on the right side of the user's nose, one nose rest portion corresponds to a first nose rest portion, and the other nose rest portion corresponds to a second nose rest portion.
In the above-described exemplary embodiment, the two second extending portions 613L and 613R are locked by one of the first locking portions 543L and 543R and the second locking portions 544L and 544R. In other words, when the two second extending portions 613L and 613R are locked by the first locking portions 543L and 543R, the second extending portion 613L is locked by the first locking portion 543L, and the second extending portion 613R is locked by the first locking portion 543R. Further, when the two second extending portions 613L and 613R are locked by the second locking portions 544L and 544R, the second extending portion 613L is locked by the second locking portion 544L, and the second extending portion 613R is locked by the second locking portion 544R. However, the exemplary embodiment is not limited to this. When the two second extending portions 613L and 613R are locked, only one second extending portion of the second extending portions 613L and 613R may be locked. In other words, one first locking portion of the first locking portions 543L and 543R may not be needed, and one second locking portion of the second locking portions 544L and 544R may not be needed. Further, when the second extending portions 613L and 613R are locked in the first position, one second extending portion of the second extending portions 613L and 613R may be locked by the first locking portion. When the second extending portions 613L and 613R are locked in the second position, the other second extending portion of the second extending portions 613L and 613R may be locked by the second locking portion.
In the above-described exemplary embodiment, the first locking portions 543L and 543R and the second locking portions 544L and 544R are recessed portions into which the second extending portions 613L and 613R fit. However, the exemplary embodiment is not limited to this. A configuration of the first locking portion is not limited to a recessed portion as long as the nose pad 6 can be locked in the first position. Similarly, a configuration of the second locking portion is not limited to a recessed portion as long as the nose pad 6 can be locked in the second position.
In the above-described exemplary embodiment, the surface in the −Z direction of the regulating portions 545L and 545R configured to regulate the rotation of the nose pad 6 disposed in the first position or the second position is located in the −Z direction with respect to the portion facing the surface in the +Z direction of the second extending portions 613L and 613R in the first locking portions 543L and 543R and the second locking portions 544L and 544R that are each a recessed portion. However, the exemplary embodiment is not limited to this. A position in the +Z direction of the regulating portions 545L and 545R with respect to the first locking portions 543L and 543R and the second locking portions 544L and 544R may be appropriately changed depending on the configuration of the first locking portions 543L and 543R and the second locking portions 544L and 544R, and the configuration of the regulating portions 545L and 545R.
In the above-described exemplary embodiment, the attachment portion 54 includes the regulating portion 545L located between the first locking portion 543L and the second locking portion 544L, and the regulating portion 545R located between the first locking portion 543R and the second locking portion 544R. However, the exemplary embodiment is not limited to this. The regulating portions 545L and 545R may not be necessarily needed in a case where the first locking portions 543L and 543R and the second locking portions 544L and 544R can sufficiently lock the nose pad 6. Further, the attachment portion 54 may be configured to include one regulating portion of the regulating portions 545L and 545R.
In the above-described exemplary embodiment, a position of the nose pad 6 can change in the attachment portion 54 by bending the second extending portions 613L and 613R in the direction closer to each other in the X axis. In other words, the nose pad 6 can rotate in the ±D direction about the shaft portion 611 by bending the second extending portions 613L and 613R in the direction closer to each other in the X axis. However, the exemplary embodiment is not limited to this. For example, the first extending portions 612L and 612R may expand and contract along the Z axis, and the second extending portions 613L and 613R are brought away from the first locking portions 543L and 543R and the second locking portions 544L and 544R, and thus a nose pad may be configured to rotate about a rotational movement shaft along the X axis and be able to have a position being changed in an attachment portion.
Further, the intersection angle αL between the first extending portion 612L and the second extending portion 613L, and the intersection angle αR between the first extending portion 612R and the second extending portion 613R are each an obtuse angle. However, the exemplary embodiment is not limited to this, and the intersection angles αL and αR may be another angle, such as a right angle.
In the above-described exemplary embodiment, the connecting portions 64L and 64R as the first connecting portion and the second connecting portion that couple the insertion portion 61 and the rocking support portions 63L and 63R in the nose pad 6 include the first components 64L1 and 64R1, the second components 64L2 and 64R2, the third components 64L3 and 64R3, and the fourth components 64L4 and 64R4. However, the exemplary embodiment is not limited to this, and a bending direction of the connecting portions 64L and 64R can be appropriately changed.
Further, the nose pad 6 also includes the rocking support portions 63L and 63R that rockingly support the nose rest portions 62L and 62R.
