Description

Technical Field

[0001] This disclosure relates to a wearing device.

Background Art

[0002] In recent years, head-mounted video display devices (head-mounted displays: HMDs) that are worn on the user's head and display video in front of the user's eyes have come into use. HMDs are used as devices that can experience virtual reality (VR) and mixed reality (MR) because they can easily display video on a large screen and provide easy stereoscopic viewing.

[0003] An HMD has a wearing device for wearing the video display device on the user's head. There are various forms of the wearing device depending on the weight, shape, and usage method of the video display device. The glasses type used in lightweight HMDs, the ring type used in high-performance HMDs, the goggle type, etc. are mainstream. Among these, the ring-type wearing device used in high-performance types mainly presses pads provided on the front and rear sides in the front and rear directions, and supports the video display device by the frictional force generated between the forehead and the back of the head.

[0004] In the configuration of an HMD equipped with this wearing device, the pad adheres to the skin on the forehead, but often sandwiches the hair at the back of the head, resulting in a decrease in the friction coefficient. Especially in women with long hair, the hair may shift between the pad and the scalp, sometimes causing an effect like a so-called "koro". Since the friction coefficient is high on the front side and low on the back side, and the video display device, which is a heavy object, is located further forward than the front pad, there is a problem that the rear pad receives an upward rotational force and the wearing device shifts. To address this problem, a countermeasure of increasing the pressing force of the wearing device can be considered, but increasing the pressing force on the head may cause discomfort to the user.

[0005] [Patent Document 1] Patent No. 7248028 [Overview of the project] [Problems that the invention aims to solve]

[0006] As a technique to suppress displacement of the HMD while reducing pressure on the head, Patent Document 1 discloses a technique for stably attaching the HMD to the head by providing a protrusion on the rear pad that contacts the back of the head of the attachment device.

[0007] However, the technology disclosed in Patent Document 1 has the problem that the protrusions are large and cannot prevent the rear pad from shifting position by pinching the hair. Even if small, thin protrusions are assumed, the tips of the protrusions may come into contact with the scalp, potentially causing discomfort to the user. In this case, the protrusions may also bend in various directions, and the stability of the posture may not be maintained.

[0008] In view of the above-mentioned problems, this disclosure aims to provide a device that can suppress the occurrence of positional displacement during wear while maintaining user comfort. [Means for solving the problem]

[0009] The mounting device of the present disclosure is a mounting device for mounting an image display device, comprising a first frame to which the image display device is connected, and a second frame connected to the first frame. A plurality of protrusions are provided on the inner surface of at least one of the first frame and the second frame, and the protrusions extend in a direction inclined with respect to a normal defined at the installation location of the inner surface. [Effects of the Invention]

[0012] -Basic Configuration of the Wearing Device in the Present Disclosure- When specifically disclosing the embodiments, the basic configuration of the wearing device in the present disclosure will be described.

[0013] The wearing device of the present disclosure is a wearing device for mounting a video display device, and includes a first frame to which the video display device is connected, and a second frame connected to the first frame. On at least one inner surface of the first frame and the second frame, a plurality of protrusions are provided, and the protrusions extend in a direction inclined with respect to the normal line defined at the installation position of the inner surface. Here, when the protrusions extend substantially parallel to the above normal line, the protrusions are pressed against the scalp substantially perpendicularly during use, so the pressure on the scalp increases, the contact state of the protrusions becomes unstable, and the user feels discomfort. In contrast, in the present disclosure, since the protrusions extend in a direction inclined with respect to the above normal line, the protrusions are inclined with respect to the scalp surface during use, and the protrusions mainly contact the scalp with a side surface having a larger area than the tip. Thereby, the contact state of the protrusions is stabilized, the discomfort of the user is alleviated, and the displacement of the wearing device is suppressed.

[0014] -Specific Description of Embodiments- Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the following embodiments do not limit the invention according to the claims. Although a plurality of features are described in the embodiments, not all of these plurality of features are essential, and the plurality of features may be arbitrarily combined. Further, in the drawings, the same or similar configurations are denoted by the same reference numerals, and redundant descriptions are omitted. The details of the dimensions and structures shown in each embodiment are not limited to those shown in the text and the drawings.

[0015] In various embodiments, the three-dimensional orthogonal coordinate axes are defined as follows. The direction from the right-eye part to the left-eye part of the video display device 200 is defined as the first direction (X-axis direction). The direction that is perpendicular to the X-axis direction and parallel to the expansion and contraction direction of the connection part 103, and from the rear pads 400, 420 to the front pads 300, 310 is defined as the second direction (Z-axis direction). The direction that is perpendicular to both the X direction and the Z direction and from the user's feet upward to the head when worn is defined as the third direction (Y-axis direction).

[0016] (First Embodiment) Hereinafter, the wearing device 100 according to the first embodiment will be described with reference to FIGS. 1 to 9.

[0017] FIG. 1 is a perspective view showing an HMD in which the video display device 200 is connected to the wearing device 100 according to the present embodiment. The wearing device 100 includes a front frame 101 which is a first frame, a rear frame 102 which is a second frame, and a connection part 103.

[0018] The front frame 101 is a member whose inner surface abuts against the user's forehead when the wearing device 100 is worn on the user's head. The front frame 101 has a detachable part 210, and the video display device 200 is detachably arranged on the outer surface of the detachable part 210. A rotary hinge may be provided on the detachable part 210 so that the video display device 200 can be held in a flip-up manner.

[0019] The rear frame 102 is a member whose inner surface abuts against the user's occipital region when the wearing device 100 is worn on the user's head. The connection part 103 is a pair of members that connect one end of the front frame 101 and one end of the rear frame 102, and the other end of the front frame 101 and the other end of the rear frame 102, respectively. The connection part 103 is formed of an expandable and contractible material, and the relative positions of the front frame 101 and the rear frame 102 can be changed in the direction of the arrow in the figure.

[0020] A front pad 300 is positioned on the inner surface of the front frame 101, and a rear pad 400 is positioned on the inner surface of the rear frame 102. The front pad 300 and the rear pad 400 are detachable. In this embodiment, the rear pad 400 has a plurality of protrusions 500. Specifically, the rear pad 400 has a rear pad base 401 and a plurality of protrusions 500 formed on the surface of the rear pad base 401.

[0021] The front pad 300 is configured so that a portion of its surface can come into contact with the skin on the user's forehead. This prevents the front pad 300 from shifting position due to hair on the forehead. The rear pad 400 is configured so that the projection 500 formed on the surface of the rear pad base 401 can part the hair on the user's back of the head and reach near the scalp. This prevents the rear pad 400 from shifting position due to hair. The rear pad 400 will be described in detail later.

[0022] Figure 2 is a schematic diagram showing the video display device 200 used in this embodiment, where (a) is a rear view and (b) is a front view. The image display device 200 has a left eyepiece unit 201L and a right eyepiece unit 201R that correspond to the left and right eyes when the user looks into it, and a left imaging camera 203L and a right imaging camera 203R that capture images corresponding to the left and right eyes.

[0023] The eyepiece units 201L and 201R are configured to be movable left and right, as shown by the arrows in Figure 2(a), by a mechanism (not shown) to adjust the distance between their lenses to match the interpupillary distance (the distance between the user's eyeballs). The mechanism for moving the eyepiece units 201L and 201R may be a slide rail mechanism operated manually by the user. Alternatively, it may be an electrically operated mechanism using an actuator such as a motor. Furthermore, the eyepiece lenses 202L and 202R of the eyepiece units 201L and 201R are equipped with display panels (not shown), allowing the user to view the image through the eyepiece lenses 202L and 202R.

[0024] The imaging cameras 203L and 203R are capable of acquiring moving images, and the video display device 200 can generate moving images using a calculation unit (not shown). Furthermore, the video display device 200 can use its calculation unit to combine computer graphics (CG) with images acquired by the imaging cameras 203L and 203R and display them as mixed reality (MR) on each display panel.

[0025] The rear pad 400 of the mounting device 100 of this embodiment will be described below. Figure 3 is a perspective view showing the mounting device 100 according to this embodiment.

[0026] The rear pad 400 of the attachment device 100 is constructed by forming a plurality of protrusions 500 made of an elastic material such as rubber on the surface of the rear pad base 401. The plurality of protrusions 500 are grouped into three groups: a central protrusion group 601, a central protrusion group 601 located in the central part of the rear pad base 401, a left-center protrusion group 602 and a right-center protrusion group 603, and a left-end protrusion group 604 and a right-end protrusion group 605. The central protrusion group 601 is a group of protrusions 500 located in the central part of the rear pad base 401. The left-center protrusion group 602 and the right-center protrusion group 603 are groups of protrusions 500 located to the left and right of the central protrusion group 601, respectively. The left end projection group 604 and the right end projection group 605 are groups of projections 500 located adjacent to the left middle projection group 602 and the right middle projection group 603, respectively, at the left and right end positions of the rear pad base 401.

[0027] Figure 4 is a schematic diagram showing the rear pad 400, where (a) is a perspective view and (b) is a cross-sectional view along the dashed line AA in (a). In the rear pad 400 of this embodiment, each projection 500 extends in a direction inclined with respect to the normal defined by the tangent plane at each installation location on the surface of the rear pad base 401. For example, as shown in Figure 4(b), for the central projection group 601, the centralmost multiple (three in the illustrated example) projections 500 extend inclined in the direction shown by the dashed line from the normal (not shown) on the surface S of the rear pad base 401, which is the tangent plane at the installation location. In other words, the centralmost multiple projections 500 in Figure 4(b) are formed inclined with respect to the surface S of the rear pad base 401 in a direction that rotates around the X axis (here, clockwise rotation, in the direction in which the tip is directed downwards in the figure).

[0028] Figure 5 is a schematic diagram showing a rear pad 410 according to a comparative example of this embodiment, where (a) is a perspective view and (b) is a cross-sectional view along the dashed line BB in (a). In the comparative example, the rear pad 410 extends without inclination in the direction of the normal defined by the tangent plane at each installation location on the surface of the rear pad base 401. For example, as shown in Figure 5(b), the multiple protrusions 510 extend in the direction of the normal shown by the dashed line on the surface S of the rear pad base 401, which is the tangent plane at the installation location.

[0029] Figure 6 is a schematic diagram illustrating the effects of providing a projection 500 on the rear pad 400 in this embodiment, based on a comparison with a comparative example, where (a) shows the comparative example and (b) shows this embodiment. When a non-inclined projection 510 is provided, as in the comparative example in Figure 5, the projection 510 is pressed perpendicularly against the head, as shown in Figure 6(a), and the small surface at the tip of the projection 510 contacts the back of the user's head. In contrast, when an inclined projection 500 is provided, as in this embodiment in Figure 4, the projection 500 tilts relative to the back of the user's head, as shown in Figure 6(b), and the side surface of the projection 500 contacts the back of the head. Therefore, the contact surface of the projection 500 with the back of the head is wider compared to the case of projection 510.

[0030] By adopting this configuration, the pressure generated when the projection 500 contacts the back of the head can be reduced, thereby reducing the discomfort felt by the user. Furthermore, with a non-inclined projection 510, when it contacts the back of the head, the projection 510 is pressed perpendicularly against the back of the head, so even a slight movement of the head causes the projection 510 to incline, and since the direction of inclination is random, it results in an unstable contact state. In contrast, with an inclined projection 500, when it contacts the back of the head, the projection 500 tilts in a predetermined direction relative to the back of the head, and the position of the projection 500 stabilizes in this tilted state. Also, stress and tension are generated internally in the inclined direction, and the shape also stabilizes. In other words, by providing an inclined projection 500, the position of the projection 500 becomes constant and stable in the inclined direction, and the shape also tends to stabilize in the inclined direction when pressed. As a result, the discomfort felt by the user is reduced, and displacement of the attachment device 100 is suppressed.

[0031] Figure 7 is a schematic diagram illustrating the pitch, yaw, and roll directions of a mounting device 100 on which an image display device 200 is mounted. Here, (a) is a side view viewed from the +X direction, showing the pitch direction (direction around the X axis). Here, a hidden line is shown on the rear pad 400. (b) is a top view viewed from the +Y direction, showing the yaw direction (direction around the Y axis). (c) is a front view viewed from the +Z direction, showing the roll direction (direction around the Z axis).

[0032] As shown in Figure 7(a), the central projection group 601 located in the central part of the rear pad base 401 is positioned at the outermost edge when viewed from the +X direction. This maximizes the moment for suppressing the pitch-direction displacement of the mounting device 100, making it possible to effectively suppress the pitch-direction displacement of the mounting device 100.

[0033] Figure 8, similar to Figure 7(b), is a top view illustrating the inclination direction of the left central projection group 602 and the right central projection group 603 as viewed from the +Y direction. The left central projection group 602 and the right central projection group 603 are positioned adjacent to both ends of the central projection group 601, which is located in the central part of the rear pad base 401. The projections 500 of the left central projection group 602 and the right central projection group 603 are formed at an inclination when viewed from the +Y direction, as shown by the dashed line in Figure 8. This makes it possible to suppress the yaw-direction displacement of the mounting device 100.

[0034] Figure 9 is a side view illustrating the inclination direction of the leftmost projection group 604 (the rightmost projection group 605 is not shown due to its symmetrical shape). The left end projection group 604 and the right end projection group 605 are positioned at the left and right ends of the rear pad base 401. The projections 500 of the left end projection group 604 and the right end projection group 605 are formed at an angle from the tangent plane (the XZ plane in the illustrated example) at the installation site, as shown by the dashed line in Figure 9. This suppresses misalignment of the mounting device 100 in the pitch direction. Furthermore, the moment for suppressing positional misalignment of the mounting device 100 in the roll direction is maximized, making it possible to effectively suppress positional misalignment of the mounting device 100 in the roll direction.

[0035] As described above, this embodiment provides a device 100 that can suppress the occurrence of positional displacement during wear while maintaining the user's comfort.

[0036] -Various variations of the first embodiment- Hereinafter, various modifications of this embodiment will be described in detail with reference to the drawings. In the various modifications, components similar to those of the mounting device 100 described in this embodiment are denoted by the same reference numerals, and detailed explanations are omitted.

[0037] (Variation 1) Figures 10 and 11 are perspective views showing the projection 500 in the attachment device 100 according to Modification 1 of the First Embodiment. In Figure 10, (a) shows the first example, (b) shows the second example, and (c) shows the third example. In Figure 11, (a) shows the fourth example, and (b) shows the fifth example. The projection 500 is preferably positioned to reach the scalp as far as possible by parting the hair, in order to prevent the attachment device 100 from slipping due to the hair.

[0038] [Example 1] In the first example, as shown in Figure 10(a), the projection 500 has a shape in which the tip portion 500A gradually narrows towards the tip surface 500a. A first small projection 501 is formed on the tip surface 500a, which is narrower than the tip surface 500a. The first small projection 501 has a small tip width (for example, 1 mm or less) and extends, for example, along the Y-axis direction. By providing a plurality of projections 500 with the desired inclination on the surface of the rear pad base 401, similar to this embodiment, the projections 500 are bent when they come into contact with the back of the head during use. At this time, the longitudinal direction of the first small projection 501 is approximately parallel to the direction of hair growth, making it easy to part the hair and reach the scalp. This makes it possible to reduce the occurrence of misalignment of the attachment device 100 due to hair.

[0039] [Example 2] In the second example, as shown in Figure 10(b), the projection 500 has a shape in which the tip portion 500B gradually narrows towards the tip surface 500b. A pair of second small projections 502 are formed on one end and the other end of the tip surface 500b. Each second small projection 502 has a small tip width (for example, 1 mm or less), and is arranged so that the direction connecting the two second small projections 502 is parallel to the Y-axis direction, for example. By providing a plurality of projections 500 with the desired inclination on the surface of the rear pad base 401, similar to this embodiment, the projections 500 are bent when they come into contact with the back of the head during use. At this time, the direction connecting the two second small projections 502 is approximately parallel to the direction of hair growth, making it easy to part the hair and reach the scalp. This makes it possible to reduce the occurrence of displacement of the attachment device 100 due to hair.

[0040] [Example 3] In the third example, as shown in Figure 10(c), the projection 500 has a shape in which the tip portion 500C gradually narrows towards the tip surface 500c. A first small projection 501 is formed on the tip surface 500c, which is narrower than the tip surface 500a. Furthermore, a third small projection 503 is formed on the side surface of the tip portion 500C, which is narrow and protrudes similarly to the first small projection 501. The first small projection 501 has a small tip width (e.g., 1 mm or less) and extends along the Y-axis direction, for example. The third small projection 503 has a small width (e.g., 1 mm or less), with one end connected to the upper part of the first small projection 501 in the Y-axis direction in the figure, and extends along the side surface of the tip portion 500C. By providing a plurality of projections 500 with the desired inclination on the surface of the rear pad base 401, similar to this embodiment, the projections 500 contact the back of the head and are bent during use. In this case, the first small projection 501 is approximately parallel to the longitudinal direction of the second small projection 503. Therefore, the first small projection 501 or the third small projection 503 can easily part the hair and reach the scalp. This makes it possible to reduce the occurrence of displacement of the attachment device 100 due to hair. In the third example, it is also conceivable to form only the small projection 503 without forming the first small projection 501.

[0041] [Example 4] In the fourth example, as shown in Figure 11(a), the projection 500 gradually tapers towards the tip of the head, and the tip surface 500d is narrow and elongated, for example, elliptical in shape. The tip surface 500d has a small tip width (for example, 1 mm or less) and extends along the Y-axis direction. By providing a plurality of projections 500 with the desired inclination on the surface of the rear pad base 401, similar to this embodiment, the projections 500 contact the back of the head and are bent during use. At this time, the longitudinal direction of the tip surface 500d is approximately parallel to the direction of hair growth, making it easy to part the hair and reach the scalp. This makes it possible to reduce the occurrence of misalignment of the attachment device 100 due to hair.

[0042] [Example 5] In the fifth example, as shown in Figure 11(b), the projection 500 gradually tapers towards the tip, with the tip portion 500E becoming narrower towards the tip, and the tip surface 500e having a small diameter and a roughly circular shape. The tip surface 500e has a small tip width (for example, 1 mm or less) even when viewed from the Y-axis direction. By providing multiple projections 500 with the desired inclination on the surface of the rear pad base 401, similar to this embodiment, the projections 500 contact the back of the head and are bent during use. At this time, the longitudinal direction of the tip surface 500e is roughly parallel to the direction of hair growth, making it easy to part the hair and reach the scalp. This makes it possible to reduce the occurrence of misalignment of the attachment device 100 due to hair.

[0043] Figure 12 is a schematic diagram illustrating the effects achieved by using the projection 500 in Modification 1. In Figure 12, (a) shows the cross-sectional view in the XZ plane when the tip of the projection 500 (here, the first small projection 501 of the first example is shown as an example) contacts the head, and (b) shows the state of the hair.

[0044] As shown in Figure 12(a), the tip of the projection 500 (the first small projection 501 in the first example shown) is formed to be narrow when viewed from the Y direction, thus increasing the effect of parting the hair 10.

[0045] As shown in Figure 12(b), it is generally known that multiple hairs 10 grow from hair follicles in the scalp 11, and the distance between hair follicles is approximately 1 mm. Therefore, if the width of the tip of the projection is clearly greater than 1 mm, the tip of the projection cannot reliably reach the scalp. If the width of the tip of the projection 500 is 1 mm or less, the tip of the projection 500 can reach the scalp. Also, if the width of the tip is 1 mm or less, the tip of the projection 500 can get closer to the scalp 11, reducing the likelihood of the attachment device 100 being displaced by the hair. In Modification 1, by having the tip of the projection 500 take the form shown in Examples 1 to 5, it is possible to reduce the occurrence of displacement of the attachment device 100 due to the hair.

[0046] (Modification 2) Figure 13 is a schematic diagram showing a mounting device 100 according to a modification 2 of the first embodiment, where (a) is a perspective view showing the mounting device 100 with the video display device 200 connected, and (b) is a front view showing the rear pad 420. The mounting device 100, similar to that of this embodiment, comprises a front frame 101 which is a first frame, a rear frame 102 which is a second frame, and a connecting portion 103.

[0047] A front pad 300 is positioned on the inner surface of the front frame 101, and a rear pad 420 is positioned on the inner surface of the rear frame 102. The front pad 300 and the rear pad 420 are detachable. In the modified example 2, the rear pad 420 has a plurality of protrusions 700. Specifically, the rear pad 420 has a rear pad base 401 and a plurality of protrusions 700 formed on the surface of the rear pad base 401.

[0048] In the rear pad 400 of the modified example 2, each projection 700 is made of an elastic material such as rubber and extends in a direction inclined with respect to the normal defined by the tangent plane at each installation location on the surface of the rear pad base 401. Specifically, the multiple projections 700 are provided in the central part of the rear pad base 401, inclined radially with respect to the inclined center line 402, which is shown by a dashed line that coincides with the Y-axis direction.

[0049] By arranging multiple radially inclined protrusions 700 around the inclined center line 402, the mounting device 100 can wrap around the back of the head with the multiple protrusions 700 when it is attached to the user's head. This makes it possible to suppress the occurrence of positional displacement in the pitch, yaw, and roll directions from the inclined center line 402. Furthermore, in the modified example 2, it is not necessary to provide multiple groups of protrusions across the entire surface of the rear pad base 401, so it is possible to reduce the number of protrusions 700.

[0050] (Second embodiment) The mounting device 100 according to the second embodiment will be described below with reference to Figure 14. Figure 14 is a schematic diagram showing the front pad 310 in this embodiment, where (a) is a perspective view and (b) is a cross-sectional view along the dashed line CC in (a). The mounting device 100, similar to the first embodiment, comprises a front frame 101 which is a first frame, a rear frame 102 which is a second frame, and a connecting portion 103.

[0051] A front pad 310 is positioned on the inner surface of the front frame 101, and a rear pad 400 is positioned on the inner surface of the rear frame 102. The front pad 310 and the rear pad 400 are detachable. In this embodiment, the rear pad 400 has a plurality of protrusions 500, and the front pad 310 has a plurality of protrusions 800 made of an elastic material such as rubber. Specifically, the front pad 310 has a front pad base 301 and a plurality of protrusions 800 formed on the surface of the front pad base 301. The rear pad 400 has a rear pad base 401 and a plurality of protrusions 500 formed on the surface of the rear pad base 401. The protrusions 500 are the same as in the first embodiment and its various modifications, so their description is omitted. In this embodiment, it is also conceivable to omit the protrusions from the rear pad 400 and provide the protrusions 800 only on the front pad 310.

[0052] The front pad 310 is configured such that the projection 800 formed on the surface of the front pad base 301 can part the hair on the user's forehead and reach close to the scalp. This prevents the front pad 310 from shifting position due to hair.

[0053] The front pad 310 of the attachment device 100 is constructed by forming a plurality of protrusions 800 on the surface of the front pad base 301. The plurality of protrusions 800 are grouped into two groups: a central protrusion group 611 and a left-end protrusion group 612 and a right-end protrusion group 613. The central protrusion group 611 is a group of protrusions 800 located in the central part of the front pad base 301. The left-end protrusion group 612 and the right-end protrusion group 613 are groups of protrusions 800 located adjacent to the central protrusion group 611 at the left and right ends of the front pad base 301, respectively.

[0054] In the front pad 310 of this embodiment, each projection 800 extends in a direction inclined with respect to the normal defined by the tangent plane at each installation location on the surface of the front pad base 301. For example, as shown in Figure 14(b), for the central projection group 611, the centralmost multiple (three in the illustrated example) projections 800 extend inclined in the direction shown by the dashed line from the normal (not shown) on the surface S of the front pad base 301, which is the tangent plane at the installation location. In other words, the centralmost multiple projections 800 in Figure 14(b) are formed inclined with respect to the surface S of the front pad base 301 in a direction that rotates around the X axis (here, clockwise rotation, in the direction in which the tip rises in the figure).

[0055] By adopting this configuration, it is possible to reduce the pressure generated when the projection 800 contacts the forehead, thereby reducing the discomfort felt by the user. Furthermore, with a projection that is not inclined, when the projection comes into contact with the forehead, it is pressed perpendicularly against the forehead, so even a slight movement of the head will cause the projection to tilt, and since the direction of tilt is random, it results in an unstable contact state. In contrast, with an inclined projection 800, when the projection 800 comes into contact with the forehead, it tilts in a predetermined direction relative to the forehead, and the position of the projection 800 stabilizes in this tilted state. Also, stress and tension are generated internally in the inclined direction, and the shape also stabilizes. In other words, by providing an inclined projection 800, the position of the projection 800 becomes constant and stable in the inclined direction, and the shape also tends to stabilize in the inclined direction when pressed. As a result, the discomfort felt by the user is reduced, and the displacement of the attachment device 100 is suppressed.

[0056] As described above, this embodiment provides a device 100 that can suppress misalignment during wear while maintaining user comfort. Furthermore, by providing multiple protrusions 500 on the rear pad 400 and multiple protrusions 800 on the front pad 310, the discomfort felt by the user is reduced, and misalignment of the device 100 is suppressed even more reliably.

[0057] Furthermore, in the first embodiment and its various modifications, as well as in the second embodiment, the front and rear pads are configured to be replaceable. Therefore, it is possible to select the optimal front and rear pads depending on the user's hair volume and hairstyle. In addition, the second embodiment can also be modified by applying modification 1 or modification 2 of the first embodiment.
