[0094] [Internal structure of the front housing]

[0095] Figure 3 are schematic diagrams each showing the internal structure of the front housing 3 . Figure 3 A shows a state of the head mounted display 1 viewed from the rear side. Figure 3 B shows the state of the front housing 3 viewed from the right side at an angle. Figure 3In the figure, the rear half of the front housing 3 is omitted so that the internal structure of the front housing 3 can be seen. In other words, only the front half of the front housing 3 (the front cover 26) is shown. Figure 3 In A, illustration of the display unit 11 is omitted.

[0096] like Figure 3 As shown, a pinion gear 27 is arranged in the front cover 26. Specifically, the pinion gear 27 is arranged at the center of the rear side surface of the front cover 26 in the left-right direction.

[0097] Further, approximately half of the end 16 side (the side inserted into the front housing 3) of the left rack 5 becomes an engagement portion 28 for engagement with the pinion 27. The engagement portion 28 has a strip shape and downward teeth (gear) are formed thereon.

[0098] Similarly, approximately half of the end 18 side (the side inserted into the front housing 3) of the right rack 6 becomes an engagement portion 29 for engagement with the pinion 27. The engagement portion 29 has a strip shape, and upward teeth are formed thereon.

[0099] The meshing portion 28 of the left rack 5 meshes with the pinion 27 from the upper side. Specifically, the downward teeth of the meshing portion 28 mesh with the teeth at the upper portion of the pinion 27. Similarly, the upward teeth of the meshing portion 29 of the right rack 6 mesh with the teeth at the lower portion of the pinion 27, so that the meshing portion 29 meshes with the pinion 27 from the lower side. Figure 3 The state in which the teeth near the end 16 and the end 18 are meshed with the teeth of the pinion 27 is shown.

[0100] The specific configuration (including shape, material, arrangement method, etc.) of the pinion gear 27 is not limited.

[0101] The pinion gear 27 corresponds to an embodiment of a coupling member according to the present technology.

[0102] Furthermore, the pinion gear 27 corresponds to an embodiment of the first adjustment mechanism according to the present technology.

[0103] The first connecting member according to the present technology is implemented by the left rack 5 , the right rack 6 , and the pinion 27 .

[0104] [Internal structure of the rear housing]

[0105] Figure 4 Schematic diagram showing the internal structure of the rear housing 4. Figure 4 The exploded view of the rear housing 4 decomposed into its components is shown as viewed from the oblique front left side. In addition, the left belt 7 and the right belt 8 are also shown.

[0106] The rear housing 4 includes a rear dial block 32 , a rear cover 33 , a battery 34 , a base plate 35 , and a rear head cover 36 . The rear dial block 32 includes a base 37 , a pinion 38 , and a rear dial 39 .

[0107] The base 37 is a member that becomes a base for the rear side (negative side of the Y axis) of the rear case 4. The base 37 is composed of a curved plate shape, and has an arc shape protruding toward the rear side when viewed from the upper side.

[0108] The pinion 38 is arranged at the center in the left-right direction of the front side (positive side of the Y axis) surface of the base 37. In the present embodiment, downward teeth are formed at the upper portion of the left belt 7. In addition, upward teeth are formed at the lower portion of the right belt. When the left belt 7 and the right belt 8 are inserted into the rear housing 4, the teeth of the left belt 7 mesh with the teeth at the upper portion of the pinion 38. In addition, the teeth of the right belt 8 mesh with the teeth at the lower portion of the pinion 38.

[0109] The rear dial 39 is a dial for rotating the pinion 38. The pinion 38 is connected to the rear dial 39 so that their rotation axes become the same. The rear dial 39 is exposed on the rear side surface of the rear housing 4, and when the user 2 rotates the rear dial 39, the pinion 38 also rotates integrally.

[0110] The specific configurations (including shapes, materials, arrangement methods, etc.) of the base 37 , the pinion 38 , and the rear dial 39 are not limited.

[0111] The pinion gear 38 corresponds to an embodiment of a second adjustment mechanism according to the present technology.

[0112] The second connection member according to the present technology is implemented by the left belt 7 , the right belt 8 , and the pinion 38 .

[0113] The belt according to the present technology is realized by a left rack 5 , a right rack 6 , a left belt 7 , a right belt 8 , a left hinge 9 , a right hinge 10 , a pinion 27 , and a pinion 38 .

[0114] The rear cover 33 is a member that becomes a base for the front side of the rear case 4. The base 37 is composed of a curved plate shape, and has an arc shape protruding toward the rear side when viewed from the upper side.

[0115] A total of two batteries 34 are arranged, one on each of the left and right sides of the front surface of the rear cover 33. Figure 4 , the position where the battery 34 is arranged is schematically indicated by a square of a hatched pattern. The battery 34 is bonded to the rear cover 33 by, for example, an adhesive sheet or the like.

[0116] In the present embodiment, power is supplied from the battery 34 to thereby realize driving of the head mounted display 1. Of course, power may be supplied from an external power source without arranging the battery 34. For example, the head mounted display 1 may also be used by connecting the head mounted display 1 to a personal computer so that power is supplied from the personal computer. In addition to these, the specific configuration (including the type, number, arrangement, etc.) of the battery 34 is not limited.

[0117] The substrate 35 is arranged at the center of the front side surface of the rear cover 33. In the present embodiment, for example, a printed circuit board (PCB), a flexible substrate, etc. are used as the substrate 35, and control of power supply from the battery 34 to various mechanisms, etc. is performed. Of course, the type of the substrate 35 is not limited to the printed circuit board and the flexible substrate, and any type of substrate 35 can be used. In addition, the specific configuration (including arrangement, etc.) of the substrate 35 is also not limited.

[0118] The back head guard 36 is a member that contacts the back of the head of the user 2. The back head guard 36 is composed of a curved plate shape, and has an arc shape protruding toward the back side when viewed from the upper side.

[0119] The back head shield 36 is arranged to cover the entire front side surface of the back cover 33. In other words, the battery 34 and the substrate 35 are clamped by the back head shield 36 and the back cover 33. By arranging the back head shield 36, when worn, the back head shield 36 rests on the back of the head of the user 2, and the fit is improved. In addition, the battery 34 and the substrate 35 are protected from external impacts. The specific configuration (including shape, material, etc.) of the back head shield 36 is not limited.

[0120] [Sliding operation of rack]

[0121] Figure 5 1 and 2 are schematic diagrams each showing a sliding operation of the left rack 5 and the right rack 6 in the front housing 3 . Figure 5 A shows a state where the vicinity of the end 16 of the left rack 5 and the vicinity of the end 18 of the right rack 6 are meshed with the pinion 27 .

[0122] In the present embodiment, each of the left rack 5 and the right rack 6 can slide in the left-right direction while maintaining a meshing state with the pinion 27. Specifically, as shown in FIG. Figure 5As shown in FIG. 1A , when a rightward force F is applied to the left rack 5, the left rack 5 slides toward the right side (in the direction indicated by arrow 1). At this time, since the downward teeth of the left rack 5 mesh with the teeth at the upper part of the pinion 27, the pinion 27 rotates clockwise (in the direction indicated by arrow 2). Therefore, since the upward teeth of the right rack 6 mesh with the teeth at the lower part of the pinion 27, the right rack 6 slides toward the left side (in the direction indicated by arrow 3).

[0123] Figure 5 B shows the left rack 5 and the right rack 6 from Figure 5 The state shown in A is the state after sliding a certain amount. Figure 5 In B, the left rack 5 slides toward the right and meshes with the pinion 27 at a portion further inside (left side) than the end 16. In addition, the right rack 6 slides toward the left and meshes with the pinion 27 at a portion further inside (right side) than the end 18.

[0124] Similarly, when a left force is applied to the right rack 6, each of the left rack 5 and the right rack 6 slides toward the inside. Conversely, when a left force is applied to the left rack 5 or a right force is applied to the right rack 6, each of the left rack 5 and the right rack 6 slides toward the outside.

[0125] Figure 6 1 and 2 are schematic diagrams each showing a slide operation of the left rack 5 by the user 2 . Figure 6 A shows a state where the vicinity of the end portion 16 of the left rack 5 is meshed with the pinion 27 . Figure 6 B shows the left rack 5 from Figure 6 The state shown in A is the state after sliding a certain amount. It should be noted that Figure 6 The right rack 6 is omitted in the figure.

[0126] like Figure 6 As shown, the user 2 holds the end 17 of the left rack 5 and applies force, and the left rack 5 and the right rack 6 slide in the left-right direction. Alternatively, the left rack 5 and the right rack 6 can also slide by applying force to the end 19 of the right rack 6.

[0127] In this embodiment, the left rack 5, the right rack 6 or the pinion 27 includes a reference point, which becomes a reference for the distance from the end 17 of the left rack 5 and the distance from the end 19 of the right rack 6, and the left rack 5 and the right rack 6 are connected by the pinion 27 so that the distance from the reference point to the end 17 of the left rack 5 and the distance from the reference point to the end 19 of the right rack 6 are synchronized.

[0128] Specifically, in this embodiment, the pinion 27 becomes the reference point. In other words, the distance from the pinion 27 to the end 17 and the distance from the pinion 27 to the end 19 are synchronized (the distances are always kept equal). Figure 5 In A, the distances are all A cm and are therefore equal.

[0129] When the left rack 5 and the right rack 6 slide from this state, as shown in FIG. Figure 5 B, the left rack 5 and the right rack 6 move an equal distance (X cm). For example, the equal distance movement is achieved by forming teeth of the same shape in each of the left rack 5 and the right rack 6.

[0130] Therefore, the respective distances after sliding become (AX) cm, and the distances are kept equal. In other words, it can also be said that the left rack 5 and the right rack 6 always maintain the state of being symmetrically arranged about the center of the pinion 27. It should be noted that the situation where the respective distances are not completely the same and are more or less different is also included in the technical scope of the present technology.

[0131] In addition, the reference point is not limited to the pinion 27, and may be, for example, a predetermined position on the left rack 5 or the right rack 6. For example, when a portion of the left rack 5 that is offset 1 cm to the left from the pinion 27 becomes a reference point, the distances from the reference point to the respective ends are kept equal relative to the reference point. In this way, the distances can be synchronized while being bilaterally asymmetrical relative to the pinion 27.

[0132] In the present embodiment, the left rack 5 and the right rack 6 are connected by the pinion 27 so that the movement of the left rack 5 and the movement of the right rack 6 are synchronized. In other words, when the left rack 5 moves, the right rack 6 also moves with it in some form. In the present embodiment, the distance moved by the right rack 6 is equal to the distance moved by the left rack 5, but the movement amount can be asymmetric, for example, when the left rack 5 moves to the right X cm, the right rack 6 moves to the left 2X cm, etc. Alternatively, when the left rack 5 moves to the right, the configuration in which the right rack 6 also moves to the right is also possible. In addition to these, any configuration in which the right rack 6 moves with the movement of the left rack 5 in some form can be adopted.

[0133] Furthermore, in the present embodiment, the left rack 5 and the right rack 6 are connected by the pinion 27 so as to be relatively movable. In other words, the relative position between the left rack 5 and the right rack 6 changes according to the rotation of the pinion 27. In the present embodiment, the relative position is changed by the movement of both the left rack 5 and the right rack 6, but it can also be said that the relative position has changed, for example, when only the left rack 5 moves. In other words, a configuration can be adopted in which only the left rack 5 moves and the right rack 6 does not move when the pinion 27 rotates. Conversely, a configuration can alternatively be adopted in which only the right rack 6 moves and the left rack 5 does not move. In addition to these, any configuration in which the left rack 5 and the right rack 6 are connected so as to be relatively movable can be adopted.

[0134] In addition, in the present embodiment, the length from the end 17 to the end 19 can be adjusted by the pinion 27. Specifically, when the user 2 applies force to the left rack 5 or the right rack 6, the pinion 27 rotates, and the left rack 5 and the right rack 6 move. Therefore, the length from the end 17 to the end 19 is changed.

[0135] For example, Figure 5 B, when the left rack 5 moves to the right by X cm and the right rack 6 moves to the left by X cm, the length from the end 17 to the end 19 is shortened by 2X cm. In other words, the length between the ends changes only by an amount corresponding to twice the amount of movement of one of the left rack 5 and the right rack 6.

[0136] In addition, the insertion amount of each of the left rack 5 and the right rack 6 increases by X cm. In other words, the lengths of the corresponding parts of the left rack 5 and the right rack 6 that are inserted into the front housing 3 and not exposed to the outside are each increased by X cm. On the contrary, the exposure amount of the left rack 5 and the right rack 6 is each reduced by X cm. In other words, the lengths of the corresponding parts of the left rack 5 and the right rack 6 that are not inserted into the front housing 3 and exposed to the outside are each reduced by X cm.

[0137] It can also be said that the length from the end 17 to the end 19 is the apparent length when the left rack 5 and the right rack 6 are regarded as an integral member. In other words, the user 2 can adjust the apparent length of the left rack 5 and the right rack 6.

[0138] In addition to these, any mechanism with which the length between the ends can be adjusted may be adopted. For example, the left rack 5 and the right rack 6 may be connected by a member other than the pinion 27, and the length between the ends may be adjusted by driving the member. Alternatively, the length between the ends may be adjusted by, for example, operating a button, a switch, a dial, or the like.

[0139] [Adjustment of the band length]

[0140] Figure 71 and 2 are schematic diagrams each showing length adjustment of the left belt 7 and the right belt 8 in the rear case 4 . Figure 7 A shows a state of the head mounted display 1 viewed from the rear side. Figure 7 B shows a state of the head mounted display 1 viewed from the right side.

[0141] In the present embodiment, the length from the end 21 of the left strap 7 to the end 23 of the right strap 8 can be adjusted by the pinion 38. Specifically, when the user 2 rotates the rear dial 39, the pinion 38 rotates, and the left strap 7 and the right strap 8 move. Therefore, the length from the end 21 to the end 23 is changed. In other words, by rotating the rear dial 39, the user 2 can adjust the apparent length of the left strap 7 and the right strap 8.

[0142] Furthermore, in the present embodiment, similarly to the case of adjusting the lengths of the left rack 5 and the right rack 6, the distance from the pinion 38 to the end 21 is synchronized with the distance from the pinion 38 to the end 23 (the distances are always kept equal). Of course, the specific configuration is not limited, and any configuration may be adopted.

[0143] exist Figure 7 In A, the rotation direction of the rear dial 39 and the movement direction of the left belt 7 and the right belt 8 are indicated by arrows. Figure 7 A clockwise (in Figure 4 When the pinion 38 rotates counterclockwise, Figure 4 At this time, since the downward teeth of the left belt 7 are meshed with the teeth at the upper part of the pinion 38, the left belt 7 is directed to the right ( Figure 4 On the contrary, the right belt 8 moves toward the left side. In other words, the distance between the ends becomes shorter.

[0144] Figure 7 B schematically shows the state in which the rear housing 4 moves with the adjustment of the distance between the end portions. When the distance between the end portions becomes shorter, the entire rear housing 4 moves toward the front side (positive side of the Y axis). On the contrary, when the rear dial 39 is Figure 5 When rotating clockwise in A, the distance between the ends becomes longer, and the rear housing 4 moves toward the rear side. In this way, by rotating the rear dial 39, the user 2 can adjust the position of the rear housing 4. In addition to these, any mechanism with which the length between the ends can be adjusted can be adopted, without being limited to the rear dial 39 and the pinion 38.

[0145] [Folding of head mounted display]

[0146] Figures 8 to 10 2 are schematic diagrams each showing a folding operation of the head mounted display 1 . Figure 8 A. Fig. 9 A and Fig.10A each shows a state of the head mounted display 1 viewed from the right side. Figure 8 B. Figure 8 C. Fig. 9 B and Fig.10 B each shows a state of the head mounted display 1 viewed from the upper side. Figure 8 B is a schematic diagram showing that the rear housing 4 is positioned Figure 8 A is a diagram of the state of the rear side. In addition, Figure 8 C is a diagram schematically showing a state in which the rear cabinet 4 moves toward the front side. Fig. 9 B is a schematic diagram showing Fig. 9 A diagram of the state of A. Fig.10 B is a schematic diagram showing Fig.10 A diagram of the state of A.

[0147] In this embodiment, by rotating the front case 3 and the rear case 4 using the left hinge 9 and the right hinge 10 as the rotation center, the rear case 4 can be accommodated inside the front case 3. The accommodation of the rear case 4 corresponds to the folding of the head mounted display 1. Specifically, first, when the user 2 is positioned at the rear case 4, Figure 8 The state of the rear side in A ( Figure 8 When the rear dial 39 is operated in the state shown in FIG. Figure 8 state shown in C).

[0148] Next, the user 2 rotates the rear housing 4 180 degrees to Fig. 9 In the present embodiment, the end 17 of the left rack 5 and the end 21 of the left belt 7 are rotatably connected via the left hinge 9. In addition, the end 19 of the right rack 6 and the end 23 of the right belt 8 are rotatably connected via the right hinge 10. Therefore, the left rack 5 and the right rack 6 and the left belt 7 and the right belt 8 are rotatably connected while using the left hinge 9 and the right hinge 10 as the rotation center.

[0149] When the user 2 rotates the rear housing 4, the left belt 7 also rotates around the left hinge 9. In other words, the relative angle of the left belt 7 and the left rack 5 about the left hinge 9 changes. Similarly, the relative angle of the right belt 8 and the right rack 6 about the right hinge 10 changes. In other words, the left belt 7 and the left rack 5 and the right belt 8 and the right rack 6 rotate while using the left hinge 9 and the right hinge 10 as the rotation center, respectively.

[0150] In addition, when the front housing 3 rotates alone without changing the position of the rear housing 4, the relative angle also changes similarly, and the rotation using the left hinge 9 and the right hinge 10 as the rotation center is realized. Alternatively, in addition, when the front housing 3 and the rear housing 4 rotate simultaneously, the rotation using the left hinge 9 and the right hinge 10 as the rotation center is realized.

[0151] In addition, the relative angle of the front housing 3 and the rear housing 4 with respect to the left hinge 9 and the right hinge 10 also changes. In other words, it can be said that the front housing 3 and the rear housing 4 also rotate when using the left hinge 9 and the right hinge 10 as the rotation center. That is, the front housing 3 and the rear housing 4 are connected by the left rack 5, the right rack 6, the left belt 7, the right belt 8, the left hinge 9 and the right hinge 10 so as to be able to rotate when using the left hinge 9 and the right hinge 10 as the rotation center.

[0152] In addition to these, any connection method that enables the front housing 3 and the rear housing 4 to be connected so as to be relatively rotatable when using a hinge as a rotation center may be adopted. For example, portions other than the ends of the rack and the belt may be connected by a hinge. Alternatively, the front housing 3 and the rear housing 4 may be connected by members other than the rack and the belt.

[0153] Next, the user 2 pushes the left rack 5 and / or the right rack 6 into the front housing 3, so that the left rack 5 and the right rack 6 are inserted into the front housing 3, and the arrangement is as follows: Fig.10 Alternatively, the left rack 5 and the right rack 6 may be inserted into the front housing 3 by pushing the rear housing 4 toward the front side.

[0154] Through such steps, the head mounted display 1 is folded. In the folded state ( Fig.10 ), the rear housing 4 is positioned on the inner side (the negative side of the Y axis) of the front housing 3. In other words, when the head mounted display 1 has a substantially annular shape in the unfolded state, the rear housing 4 is positioned in a direction corresponding to the inner side of the annular shape. In addition, in the folded state ( Fig.10 ), the volume of the head mounted display 1 becomes smaller than that in the unfolded state ( Figure 8 The specific method of folding is not limited, and for example, any method such as a method of automatically performing folding by operating a button, a switch, etc. may be adopted.

[0155] In other words, the state in which the rear case 4 is accommodated inside the front case 3 can also be said to be a state in which the front case 3 overlaps the rear case 4. Similarly, the folded state can also be said to be a state in which the front case 3 overlaps the rear case 4.

[0156] Alternatively, you can perform the reverse steps ( Fig.10 → Fig. 9 → Figure 8 ) to return the head mounted display 1 to the unfolded state. In other words, the head mounted display 1 can be returned to the unfolded state by pulling the left rack 5 and the right rack 6 to pull them out of the front case 3, rotating the rear case 4 180 degrees, and moving the rear case 4 toward the rear side by operating the rear dial 39.

[0157] [Stop]

[0158] Fig.11 are schematic diagrams each showing a configuration example of a stopper. Fig.11 A shows a state where the front housing 3 and the left rack 5 are viewed from the rear side. Fig.11 B is along Fig.11 A is a cross-sectional view taken along line AA; it should be noted that Fig.11 Only the front half (front cover 26) of the front housing 3 is shown.

[0159] In the present embodiment, the left rack 5 includes a stopper 42 that restricts the left rack 5 from being separated from the front housing 3. Specifically, a screw is connected to the left rack 5 as the stopper 42. The stopper 42 is connected so that its tip protrudes from the front side (positive side of the Y axis) surface of the left rack 5. In addition, the front cover 26 includes a rectangular recess 43 on its rear side surface. The tip of the stopper 42 abuts against the recess 43 of the front cover 26.

[0160] For example, when Fig.11 When the left rack 5 is pulled toward the left side in the state shown, the stopper 42 also moves toward the left side, and finally gets stuck on the left side surface of the recess 43, and thus cannot move toward the left side any more. Therefore, the left rack 5 cannot move toward the left side any more. In other words, the left rack 5 will not completely detach from the front housing 3 due to excessive movement of the left rack 5 toward the left side.

[0161] In addition, since the movement of the left rack 5 and the right rack 6 is synchronized, when the movement of the left rack 5 stops, the movement of the right rack 6 also stops at the same time, and therefore the right rack 6 will not be completely separated from the front housing 3.

[0162] In other words, the stopper 42 limits the change in the distance from the pinion 27 to the end 17 of the left rack 5 so that the distance from the pinion 27 to the end 17 does not become greater than a predetermined length. In this example, the distance from the pinion 27 to the side surface of the recess 43 corresponds to the predetermined length.

[0163] In addition, it can also be said that the change in distance is restricted so that the insertion amount does not become less than a predetermined length. Alternatively, it can also be said that the change in distance is restricted so that the exposure amount does not become greater than a predetermined length. The specific value of the predetermined length is not limited, and an arbitrary value can be used.

[0164] The specific configuration (including the position of the stopper 42, the shape of the recess 43, etc.) is not limited. In addition, any method for limiting the separation of the left rack 5 and the right rack 6 may be adopted, such as a configuration using the stopper 42 other than a screw and a configuration in which the stopper 42 is connected to the right rack 6. On the contrary, the stopper 42 that limits the movement of the left rack 5 may be provided so that the insertion amount of the left rack 5 does not become greater than a predetermined length (does not move too much toward the right side). The stopper 42 corresponds to an embodiment of the limiting portion according to the present technology.

[0165] [Locking mechanism]

[0166] In the present embodiment, a snap-fit ​​mechanism is provided for generating a snap-fit ​​feeling when moving the left rack 5. Specifically, a leaf spring 44 is connected to the left rack 5. The leaf spring 44 is fixed to the rear side surface of the left rack 5 by a stopper 42 (screw). In addition, a step portion 45 is formed on the front side surface inside the front housing 3. Fig.11 B schematically shows the step portion 45 .

[0167] The tip of the leaf spring 44 contacts the step 45, and when the left rack 5 moves, the force received by the leaf spring 44 from the step 45 changes periodically as the position of the leaf spring 44 changes. Therefore, the force required to move the left rack 5 also changes periodically. Therefore, the user 2 feels a click when moving the left rack 5.

[0168] The specific configuration (including the shape, positioning and connection method of the leaf spring 44 , the shape of the step portion 45 , etc.) is not limited. In addition, the engaging mechanism may be formed by members other than the leaf spring 44 and the step portion 45 .

[0169] [Flexible substrate]

[0170] Fig.12 are schematic diagrams each showing a configuration example of a flexible substrate. Fig.12 A shows a state of the head mounted display 1 viewed from the right side diagonally in front. Fig.12 B shows the state of the head mounted display 1 viewed from the oblique front left side. Fig.13 is an exploded view showing a configuration example of a flexible substrate.

[0171] In the present embodiment, the head mounted display 1 includes a flexible substrate 48 and a harness 49, which are arranged in the left belt 7 and the left rack 5 and electrically connect the display unit 11 and the substrate 35. The flexible substrate 48 is a rectangular belt-shaped substrate and is arranged along the front side surface of the left belt 7. Specifically, in the state where the flexible substrate 48 is arranged, the flexible substrate 48 includes a right (positive side of the X axis) end portion and a front (positive side of the Y axis) end portion.

[0172] Note that although Figure 4In the example shown in FIG. 1 , the left belt 7 and the right belt 8 are hollow, but when the flexible substrate 48 is arranged in the left belt 7, the flexible substrate 48 is used as shown in FIG. Fig.12 and Fig.13 The non-hollow left belt 7 shown in FIG. Of course, the hollow left belt 7 and the right belt 8 may also be used without arranging the flexible substrate 48 or the like.

[0173] The rear cover 33 is provided with an opening 50 through which the flexible substrate 48 passes. The right (positive side of the X axis) end portion of the flexible substrate 48 is folded inside the rear housing 4, and the end is exposed to the front side of the rear housing 4 from the opening 50 to be connected to the substrate 35 arranged on the front side surface of the rear cover 33. Note that Fig.12 In FIG. 4 , the rear cover 33 is shown in a transparent manner so that the portion of the flexible substrate 48 located inside the rear housing 4 can be seen. In addition, the illustration of the opening 50 is omitted.

[0174] Furthermore, the left hinge 9, the end 17 of the left rack 5, and the end 21 of the left belt 7 are each provided with an opening 51 through which the harness 49 passes. The harness 49 has one end connected to the front end of the flexible substrate 48, arranged along the front side surface of the left belt 7, passing through the opening 51, and arranged along the front side surface of the left rack 5. The other end of the harness 49 (the end on the side not connected to the flexible substrate 48) is connected to the display unit 11.

[0175] In other words, the substrate 35 and the display unit 11 are electrically connected through the flexible substrate 48 and the harness 49. In addition, since the substrate 35 is electrically connected to the battery 34, the battery 34 and the display unit 11 are electrically connected. Therefore, power is supplied from the battery 34 to the display unit 11. Therefore, it becomes possible to display a video by the display unit 11.

[0176] The specific configuration (including type, shape, arrangement, etc.) of the flexible substrate 48 and the harness 49 is not limited. For example, the flexible substrate 48 and the harness 49 may be arranged relative to the right rack 6 and the right belt 8. Alternatively, the electrical connection may be achieved only through the flexible substrate 48 without using the harness 49. Alternatively, the electrical connection may be achieved only through the harness 49. Note that "electrical connection" includes any connection form for electrically connecting various components. For example, the electrical connection of various components via a circuit configuration including the substrate 35, the flexible substrate 48, etc. is included in the "electrical connection".

[0177] The wire harness 49 corresponds to an embodiment of the electric cable according to the present technology.

[0178] The electrical connection portion according to the present technology is implemented by the flexible substrate 48 and the harness 49 .

[0179] Alternatively, the electrical connection may be achieved by any member other than the flexible substrate 48 and the harness 49. Alternatively, mechanisms other than the substrate 35 and the display unit 11 may also be electrically connected to each other.

[0180] [Circuit Configuration]

[0181] An example of a circuit configuration in the head mounted display 1 will be described. For example, a connector may be arranged in the rear case 4, and a cable or the like (flexible substrate 48, harness 49, etc.) may be connected to the substrate 35 via the connector. Of course, a cable or the like may be directly electrically connected to the substrate 35 without using a connector.

[0182] Similarly, a cable or the like can be connected to a display (display unit 11) via a connector. In this case, for example, a substrate, a connector connected to the substrate, a processor connected to the substrate, and a display connected to the substrate are arranged in the front housing 3. Then, by connecting the cable or the like to the connector, an electrical connection between the cable or the like and the display is achieved. Of course, the specific electrical configuration in the front housing 3 is not limited. Alternatively, the cable or the like can be directly electrically connected to the substrate and the display without using a connector.

[0183] [Sub-cover]

[0184] Fig.14 are schematic diagrams each showing a configuration example of a sub-cover. Fig.14 A and Fig.14 B each shows a state of the rear cover 33 and the sub-cover 54 viewed from the oblique front left side. Fig.14 C shows the state of the rear cover 33 and the sub-cover 54 viewed from the left side obliquely behind. Note that Fig.14 A shows a state where the sub-cover 54 is removed, and Fig.14 B and Fig.14 C each shows a state in which the sub cover 54 is connected to the rear cover 33 .

[0185] Fig.15 A and Fig.16 A each shows a state where the rear case 4 , the flexible substrate 48 , and the sub cover 54 are viewed from the upper side. Fig.15 B and Fig.16 B each shows a state of the flexible substrate 48 viewed from the front side. Fig.15 C and Fig.16 C each schematically shows the state of the left belt 7, the flexible substrate 48, and the sub-cover 54 viewed from the upper side. Note that, Fig.15 A to Fig.15 C shows the flexible substrate 48 in the same state, Fig.16 A to Fig.16 C also shows the flexible substrate 48 in the same state.

[0186] In the present embodiment, the flexible substrate 48 is deformed as the pinion gear 38 adjusts the length from the end 21 of the left belt 7 to the end 23 of the right belt 8 . Fig.16 Each shows a left belt 7 from Fig.15 The state shown is a state of moving toward the right side (positive side of the X axis). Before the left belt 7 moves ( Fig.15 ), the folded portion of the flexible substrate 48 is roughly a small circle. When the left belt 7 moves toward the right, the flexible substrate 48 is pressed toward the right side (positive side of the X axis), and after the movement ( Fig.16 ), the folded portion becomes a large circle. In this way, when the left belt 7 is moved to adjust the length from the end 21 to the end 23, the flexible substrate 48 is deformed.

[0187] Furthermore, in this embodiment, the deformed flexible substrate 48 is accommodated in the sub-cover 54. Fig.14 As shown, the sub-cover 54 has a rectangular band shape, wherein one end of the sub-cover 54 is folded into a substantially circular shape. Two screw holes are formed at the end of the unfolded side of the sub-cover 54, and the sub-cover 54 is fixed to the front side surface of the rear cover 33 by screwing. In addition, the rear cover 33 is formed with a rectangular opening 55, and the sub-cover 54 is arranged so that the folded portion (the end of the folded side) enters the inner portion of the rear housing 4 from the opening 55.

[0188] like Fig.16 A and Fig.16 As shown in FIG. 3C , when the folded portion of the flexible substrate 48 becomes larger, the entire folded portion will eventually abut along the inner surface of the sub-cover 54. In this way, the flexible substrate 48 is accommodated in the sub-cover 54.

[0189] The sub-cover 54 is formed of, for example, a material having rigidity (e.g., metal and plastic). Therefore, even when a force is applied to the sub-cover 54 by deformation of the flexible substrate 48, the unfixed portion (folded portion) of the sub-cover 54 will not move. Alternatively, a configuration in which the folded portion is also fixed by fastening with screws or the like, a configuration in which the folded portion is fixed by designing the shape of the opening 55, a configuration in which the rear cover 33 and the sub-cover 54 are formed integrally, etc. may be adopted.

[0190] The circular shape of the folded portion of the sub-cover 54 may also be referred to as an R shape, etc. In addition to these, the specific configuration of the sub-cover 54 (including shape, material, arrangement, fixing method relative to the rear cover 33, etc.) is not limited. The sub-cover 54 corresponds to an embodiment of the receiving member according to the present technology.

[0191] [Hinge]

[0192] Fig.17 and Fig.18 are schematic diagrams each showing a configuration example of a hinge. Fig.18Each shows the vicinity of the left hinge 9 ( Fig.17 The rectangular portion indicated by the dotted line in FIG. Fig.18 A is along Fig.17 A cross-sectional view taken along line BB. Fig.18 B shows a state of the end portion 21 of the left belt 7 viewed from the left side (the negative side of the X axis). Fig.18 C shows the state of the left rack 5 and the left belt 7 viewed from the right side.

[0193] In this embodiment, the relative rotation angle of the front housing 3 and the rear housing 4 around the left hinge 9 and the right hinge 10 is fixed at a predetermined angle by the left hinge 9 and the right hinge 10. Specifically, the left hinge 9 and the right hinge 10 include a mechanism for fixing the rotation angle.

[0194] The left hinge 9 includes a rear belt plate 58, a leaf spring 59, and an axle pin 60. The rear belt plate 58 is a member having an annular shape. An opening 61 for attaching the left hinge 9 is formed at the end 21 of the left belt 7, and the rear belt plate 58 is fitted into and fixed to the opening 61. A positioning groove is formed on the left (negative side of the X-axis) surface of the rear belt plate 58.

[0195] The positioning groove is a groove for positioning the leaf spring 59. In the present embodiment, when the upper side (positive side of the Z axis) of the rear belt plate 58 is assumed to be the 12 o'clock direction, the positioning groove 62 is formed in the 3 o'clock direction and the 9 o'clock direction, respectively. In addition, the positioning groove 63 is formed at a position slightly deviated from the 3 o'clock direction in the clockwise direction and at a position slightly deviated from the 9 o'clock direction in the clockwise direction, respectively. In addition, the positioning groove 64 is formed at a position slightly deviated from the 3 o'clock direction in the counterclockwise direction and at a position slightly deviated from the 9 o'clock direction in the counterclockwise direction, respectively.

[0196] The leaf spring 59 is a member having an annular shape. Two protrusions 65 are formed on one surface of the leaf spring 59. The two protrusions 65 are formed at positions opposite to each other (positions deviated by 180 degrees). The leaf spring 59 is arranged so that the protrusion 65 fits into any one of the positioning grooves 62 to 64. Therefore, the leaf spring 59 is positioned on the rear belt plate 58. In addition, the surface of the leaf spring 59 on one side where the protrusion 65 is not formed is fixed to the left rack 5. Fig.18 B shows a state where the projection 65 is fitted into the positioning grooves 62 formed in the 3 o'clock direction and the 9 o'clock direction, respectively.

[0197] The shaft pin 60 is a cylindrical pin member. Since both the rear belt plate 58 and the leaf spring 59 have an annular shape, the rear belt plate 58 and the leaf spring 59 include a circular opening, and the shaft pin 60 is arranged to fit into the opening. Since the shaft pin 60 is cylindrical, the shaft pin 60 also includes a circular opening, and the wire harness 49 passes through the opening of the shaft pin 60. Note that Fig.18 In B, the shaft pin 60 is omitted from illustration.

[0198] For example, Fig.18 B, when the convex portion 65 is positioned in the positioning groove 62, the angle difference between the left rack 5 and the left belt 7 becomes 180 degrees. In other words, the angle difference between the front shell 3 and the rear shell 4 also becomes 180 degrees. In addition, when the convex portion 65 is positioned in the positioning groove 63, the left belt 7 and the rear shell 4 rotate more or less in the clockwise direction, and thus the angle difference (angle difference on the upper side) increases (for example, 200 degrees). In addition, when the convex portion 65 is positioned in the positioning groove 64, the left belt 7 and the rear shell 4 rotate more or less in the counterclockwise direction, and thus the angle difference decreases (for example, 165 degrees).

[0199] At the same time, since the protrusion 65 will not be positioned at a position other than the position where the positioning grooves 62 to 64 are formed, the angle difference will not be fixed at a half-range angle that is not a design angle. In this way, the relative rotation angle of the front housing 3 and the rear housing 4 is fixed at a plurality of predetermined angles. Note that in this embodiment, a similar mechanism is also formed in the right hinge 10.

[0200] By properly adjusting the position of the positioning groove, the number of rotation angles used for fixing and the value of the rotation angle can be arbitrarily set. In addition to these, the specific configuration (including shape, material, type, arrangement, etc.) of the rear belt plate 58, the leaf spring 59, and the shaft pin 60 is not limited. The fixing mechanism according to the present technology is realized by the rear belt plate 58, the leaf spring 59 and the shaft pin 60.

[0201] In addition, the fixing of the rotation angle is not limited to the method using the positioning groove and the protrusion 65, and can be achieved by any other method. For example, a configuration in which the user 2 can set a favorable rotation angle can be adopted. In this case, for example, the user 2 adjusts the front shell 3 and the rear shell 4 to the desired setting angle and saves the rotation angle (for example, presses a save button, etc.). The rotation angle is detected by an electronic sensor and stored in a memory. Then, when the head-mounted display 1 is activated, the rotation angle is electrically fixed at the rotation angle. For example, a rotation motor or the like is set in the left hinge 9 and the right hinge 10 to achieve electric drive.

[0202] Thus far, in the head mounted display 1 according to the present embodiment, the front case 3 and the rear case 4 are connected so as to be rotatable about the left hinge 9 and the right hinge 10. In addition, the display unit 11 and the substrate 35 are electrically connected. Therefore, the convenience of the user 2 can be improved.

[0203] When the head mount display 1 is used outdoors or the like, for example, the head mount display 1 is carried in a bag. It has become a problem to miniaturize the head mount display 1 when not in use so that the head mount display 1 can be accommodated even when the bag is small.

[0204] In the present embodiment, the distance from the end 21 of the left belt 7 to the end 23 of the right belt 8 is adjusted by the pinion 38. In other words, the user 2 can operate the rear dial 39 to move the rear housing 4 toward the front side ( Figure 8 ). Therefore, when not in use, the head mounted display 1 can be miniaturized.

[0205] In addition, the front housing 3 and the rear housing 4 are connected via the left hinge 9 and the right hinge 10 so as to be relatively rotatable. In other words, the user 2 can fold the head mounted display 1 ( Fig. 9 ). Therefore, the head mounted display 1 can be further miniaturized.

[0206] In addition, the length from the end 17 of the left rack 5 to the end 19 of the right rack 6 is adjusted by the pinion 27. In other words, the user 2 can move from the state where the front housing 3 is folded ( Fig. 9 ) Insert the left rack 5 and the right rack 6 into the front housing 3 ( Fig.10 ). Therefore, the head mounted display 1 can be further miniaturized.

[0207] Furthermore, the user 2 can adjust the outer circumference of the head mounted display 1 by inserting and pulling out the left rack 5 and / or the right rack 6 and operating the rear dial 39. Therefore, the outer circumference can be appropriately adjusted according to the head size of the user 2, so it is difficult for the head mounted display 1 to become loose and fall off the head or be too tight on the head.

[0208] Furthermore, since the engaging mechanism is provided in the left rack 5, a sense of engagement can be given to the user 2 when the user 2 adjusts the left rack 5 and / or the right rack 6. Therefore, the user 2 can easily perform adjustment to the intended position. In addition, since a certain amount of force is required to move the left rack 5 and the right rack 6, there will be no situation where the left rack 5 and the right rack 6 become loose due to the reaction force from the head when the head mounted display 1 is worn.

[0209] In addition, the left rack 5, the right rack 6, the left belt 7 and the right belt 8 are rotatably connected while using the left hinge 9 and the right hinge 10 as the rotation center. Therefore, the front case 3 and the rear case 4 are stably connected and can therefore stably rotate.

[0210] Furthermore, the end 17 of the left rack 5 and the end 21 of the left belt 7 are rotatably connected via the left hinge 9. In addition, the end 19 of the right rack 6 and the end 23 of the right belt 8 are rotatably connected via the right hinge 10. Therefore, the left rack 5, the right rack 6, the left belt 7, and the right belt 8 are stably connected, and thus can stably rotate.

[0211] Furthermore, the left rack 5 and the right rack 6 are coupled to be relatively movable via the pinion 27. Therefore, the length between the end portions can be accurately adjusted.

[0212] Furthermore, the left rack 5 and the right rack 6 are connected by the pinion 27 so that the movement of the left rack 5 and the movement of the right rack 6 are synchronized. Therefore, even when only the left rack 5 moves, the right rack 6 also moves therewith, and thus there is no need to separately move the left rack 5 and the right rack 6. In other words, the cumbersome work for adjustment can be omitted, and thus the convenience is improved.

[0213] Furthermore, the left rack 5 and the right rack 6 are connected by the pinion 27 so that the distance from the pinion 27 to the end 17 of the left rack 5 is synchronized with the distance from the pinion 27 to the end 19 of the right rack 6. Therefore, the user 2 can move the left rack 5 and the right rack 6 bilaterally symmetrically, and thus there will be no situation where the position of the front case 3, the rear case 4, or the display unit 11 is tilted and deviated when the head mounted display 1 is worn.

[0214] Furthermore, the stopper 42 restricts the left rack 5 from being separated from the front housing 3. Therefore, there will be no situation where the connection of the left rack 5 and the right rack 6 with respect to the front housing 3 is accidentally dropped.

[0215] In addition, the stopper 42 limits the change in distance so that the distance from the pinion 27 to the end 17 of the left rack 5 does not become greater than a predetermined length. Therefore, a configuration that matches the specifications of the head mounted display 1 can be appropriately adopted, for example, a configuration in which the left rack 5 cannot be pulled out more than a certain amount.

[0216] Furthermore, the display unit 11 and the substrate 35 are electrically connected through the flexible substrate 48 and the harness 49. Therefore, the battery 34 can be arranged in the rear case 4. In addition, power is stably supplied to the display unit 11, and thus the display unit 11 can operate stably.

[0217] Furthermore, the deformed flexible substrate 48 is accommodated in the sub-cover 54. Therefore, it is difficult for the deformed flexible substrate 48 to hinder the operation of other mechanisms.

[0218] Furthermore, in the present embodiment, the battery 34 is arranged in the rear case 4. In other words, since an external power source is not required, the head mounted display 1 becomes portable, etc., which means that the convenience of the user 2 is improved. Furthermore, a balanced arrangement can be achieved in which the display unit 11 having a relatively large weight is connected to the front case 3 and the battery 34 is arranged in the rear case 4.

[0219] Furthermore, the relative rotation angle of the front housing 3 and the rear housing 4 is fixed at a predetermined angle by the left hinge 9 and the right hinge 10 . Fig.19 2 are schematic diagrams each showing an example of the rotation angle of the front case 3 and the rear case 4 . Fig.19 A to Fig.19 D shows states where the rotation angles are 180 degrees, 200 degrees, 165 degrees, and 145 degrees, respectively. Fig.19 E shows a state where a woman wears the head mounted display 1 .

[0220] like Fig.19 A to Fig.19 As shown in FIG. 3 , the relative rotation angle of the front shell 3 and the rear shell 4 can be fixed at a plurality of predetermined angles. In other words, the position of the rear shell 4 can be fixed at a predetermined position. Therefore, the user 2 can appropriately set the position of the rear shell 4 according to the size or shape of the head so that the rear shell 4 can be easily worn.

[0221] In addition, if Fig.19 As shown in FIG. E, even when a woman with a ponytail wears the head mounted display 1, the rear housing 4 can be adjusted to a position that does not interfere with the ponytail. Therefore, there will be no situation where the hairstyle is ruined when the head mounted display 1 is worn.

[0222] Furthermore, since the leaf spring 59 is positioned at a predetermined position relative to the rear belt plate 58, a snapping feeling is provided to the user 2 when adjusting the rotation angle. Therefore, the user 2 can easily perform adjustment to the desired rotation angle. In addition, since a certain amount of force is required for rotation, it is difficult for the front housing 3 and the rear housing 4 to rotate unintentionally.

[0223] <Second Embodiment>

[0224] A more detailed embodiment of the head mount display 1 according to the present technology will be described as a second embodiment. In the following description, description of portions similar to those of the configuration and operation of the head mount display 1 described in the above embodiment will be omitted or simplified.

[0225] [Wire harness winding]

[0226] Figure 20 to Figure 22 1 and 2 are schematic diagrams each showing a wiring example of the wire harness 49 . Fig. 20 and Fig.21 Each shows the state of the rear case 4 and the left belt 7 viewed from the front. Fig. 20 and Fig.21 , the rear housing 4 is shown in a transparent manner so that the wiring harness 49 and the like positioned inside the rear housing 4 can be seen. Fig. 22 A shows the state of the rear cover 33 viewed from the left side obliquely behind. Fig. 22 B shows the state of the left belt 7 viewed from the front side.

[0227] In this embodiment, the display unit 11 and the substrate 35 are connected only by the harness 49. In other words, the flexible substrate 48 is not used for connection. One end of the harness 49 is connected to the substrate 35 and inserted into the interior of the rear case 4 from the opening 50 formed in the rear cover 33.

[0228] In the present embodiment, the wire harness 49 is wound by the harness drum 68 according to the adjustment of the length from the end 21 of the left belt 7 to the end 23 of the right belt 8 by the pinion 38. The harness drum 68 is a cylindrical member and has a gear-type flange portion 69 formed at one end thereof. The harness drum 68 is arranged on the rear side (negative side of the Y-axis) surface of the rear cover 33. Specifically, two upper convex portions and a lower convex portion including an opening are formed at a position further to the left than the center in the left-right direction of the rear side surface of the rear cover 33. The two ends of the harness drum 68 are respectively inserted into the openings of the convex portions, and at the same time, the end of one side of the harness drum 68 formed with the flange portion 69 faces downward, thereby fixing the harness drum 68 to the rear cover 33. The harness drum 68 is capable of rotating using the up and down direction as the center axis.

[0229] The harness drum 68 is formed of a material such as metal, for example. The specific configuration (including shape, material, arrangement method, etc.) of the harness drum 68 is not limited. The harness drum 68 corresponds to an embodiment of a winding member according to the present technology.

[0230] The wire harness 49 inserted into the interior of the rear housing 4 from the opening 50 is inserted into the lower end of the harness drum 68. An opening is formed at the side near the lower end of the harness drum 68, and the wire harness 49 passes through the opening to be exposed from the side of the harness drum 68. The exposed wire harness 49 is wound around the harness drum 68.

[0231] In the present embodiment, a groove portion 70 into which the harness 49 is press-fitted is formed in the left belt 7. The groove portion 70 extends from the lower right to the upper left on the front side surface of the left belt 7 ( Fig. 20 Of course, the specific shape of the groove portion 70 is not limited.

[0232] The harness 49 wound on the harness drum 68 is press-fitted into the groove 70 of the left belt 7. Then, the harness 49 is pressed into the groove 70 at the terminal end ( Fig. 20 A is separated from the left belt 7 at the upper right terminal), passes through the opening of the left hinge 9, is wired to be arranged along the front surface of the left rack 5, and is connected to the display unit 11.

[0233] Furthermore, an engaging portion 71 is formed at the lower edge of the left belt 7 . The engaging portion 71 has teeth facing the front side, and the teeth of the engaging portion 71 are engaged with the teeth of the flange portion 69 of the harness drum 68 .

[0234] Fig.21 Each shows a left belt 7 from Fig. 20The state shown in the figure is towards the right ( Fig. 20 and Fig.21 When the left belt 7 moves toward Fig. 20 and Fig.21 When the harness drum 68 moves to the left in the drawing, the harness drum 68 rotates clockwise when viewed from the bottom because the flange portion 69 and the meshing portion 71 of the harness drum 68 mesh with each other. Therefore, the harness 49 pressed into the groove portion 70 is separated from the groove portion 70 and wound by the harness drum 68. Fig.21 The winding amount in is greater than Fig. 20 The amount of winding in .

[0235] Fig.23 2 is a schematic diagram showing an example of the winding angle of the wire harness 49 . Fig.23 The angle (α) of the groove portion 70 relative to the left-right direction (X-axis direction) is shown. The winding angle of the wire harness 49 wound around the wire harness drum 68 is also shown.

[0236] In the present embodiment, the groove 70 and the harness drum 68 are designed so that the angle α of the groove 70 and the winding angle of the harness 49 are equal. For example, the angle α and the angle The angle α can be matched with the angle α by adjusting the inclination of the groove 70 when the groove 70 is formed, adjusting the diameter of the harness drum 68, etc. The specific method of matching is not limited.

[0237] When the angle α and the angle When the angle is different, it will cause deviation in the winding position 72 of the wire harness 49. When the angle α is less than α, as the wire harness 49 is wound, the winding position 72 in the wire harness drum 68 gradually deviates toward the lower side relative to the winding position 72 in the groove portion 70. When the angle α is greater than, the winding position 72 in the harness drum 68 deviates toward the upper side relative to the winding position 72 in the groove portion 70. In other words, in these cases, the harness 49 cannot be smoothly wound, and thus causes trouble in the winding of the harness 49 or the operation of the left belt 7.

[0238] In this embodiment, the angle α and the angle In other words, it can also be said that the pitch of the harness drum 68 matches the pitch of the groove portion 70. Alternatively, it can also be said that the vertical movement amount 73 (indicated by the arrow) of the groove portion 70 matches the vertical movement amount 73 of the harness 49 wound on the harness drum 68. Note that the angle α and the angle May also be called the pitch angle.

[0239] Note that a torsion spring may be arranged in the harness drum 68. Therefore, tension is generated in the harness 49, and the operation of the harness drum 68 and the left belt 7 is stabilized. In addition to these, the method of winding the harness 49 is not limited to the method using the harness drum 68, and the harness 49 may be wound by other methods.

[0240] [Press-fitting of wiring harnesses]

[0241] Fig.24 and Fig.25 are schematic diagrams each showing a configuration example of a harness pusher flange. Fig.24 A shows a state where the rear housing 4 is viewed from the front side. Fig.24 B is along Fig.24 A cross-sectional view taken along line CC. Fig.25 A shows the state of the rear cover 33 viewed from the left side obliquely behind. Fig.25 The left belt 7 is shown as viewed from the front.

[0242] In the present embodiment, the harness 49 is press-fitted into the groove portion 70 by the harness pusher flange 75 according to the adjustment of the length from the end 21 of the left belt 7 to the end 23 of the right belt 8 by the pinion gear 38 .

[0243] The harness pusher flange 75 is a member having a rectangular plate shape, and is arranged on the rear side surface of the rear cover 33 to be parallel to the YZ plane. The harness pusher flange 75 may be connected to the rear cover 33 as a member different from the rear cover 33, or may be formed integrally with the rear cover 33. In addition to these, the specific configuration (including material, shape, arrangement, etc.) of the harness pusher flange 75 is not limited. The harness pusher flange 75 corresponds to an embodiment of a press-fit member according to the present technology.

[0244] Press-fit points 76 are formed in the groove portion 70 of the left belt 7 at predetermined intervals. Fig.25 In FIG. 1B , the position of the press-fit point 76 is schematically indicated by a small square. The width of the groove portion 70 becomes smaller at the press-fit point 76 outside the groove portion 70, so that the harness 49 is tightly fixed. On the other hand, at the portion of the groove portion 70 other than the press-fit point 76, the harness 49 is loosely fitted.

[0245] When the left belt 7 faces the left side ( Fig.24 When the wire harness 49 is moved to the right side in A, the wire harness 49 wound on the wire harness drum 68 is separated from the wire harness drum 68 and temporarily placed in a state of not being press-fitted into the groove portion 70. Thereafter, the wire harness 49 contacts the wire harness pusher flange 75, is pushed toward the rear side (the negative side of the Y axis), and is press-fitted at the press-fit point 76. In other words, Fig.24In A, the harness 49 is not press-fitted into the groove portion 70 at the portion between the harness drum 68 and the harness pusher flange 75 (slightly floating relative to the left belt 7), but is press-fitted on the right side.

[0246] Fig.26 is a schematic diagram showing a design example of the harness pusher flange 75 and the press-fit point 76 . Fig.26 Each shows a diagram of the rear cover 33 , the wire harness 49 , and the press-fit point 76 viewed from the left side. Fig.26 A shows a view of a portion where the harness pusher flange 75 does not exist. Fig.26 B is a diagram showing a portion where the harness pusher flange 75 exists.

[0247] exist Fig.26 In A, the distance X between the rear cover 33 and the harness 49 at the portion where the harness pusher flange 75 is not present is indicated by an arrow. Fig.26 B shows the length X+α of the harness pusher flange 75. In other words, Fig.26 In B, the harness 49 is Fig.26 A is press-fitted by a distance α further toward the right. The values ​​of the distance X and α are appropriately set so that the wire harness 49 is sufficiently press-fitted.

[0248] also, Fig.26 B shows the diameter A of the harness 49 and the diameter B of the groove portion 70 at the press-fit point 76. The diameter B of the groove portion 70 is designed to be slightly smaller than the diameter A of the harness 49. In other words, the diameter of the harness 49 is A under normal circumstances, but becomes B in a state where the harness 49 is deformed to shrink longitudinally and is press-fitted during press-fitting.

[0249] Therefore, since the elastic force of the wire harness 49 trying to recover from deformation during press-fitting continues to act on the press-fit point 76, friction is generated between the wire harness 49 and the press-fit point 76, so that the wire harness 49 is difficult to fall off. In other words, the wire harness 49 is tightly press-fitted. While taking into account the diameter and material of the wire harness 49, the material of the left belt 7, etc., the values ​​of the diameter A and the diameter B are appropriately set so that the wire harness 49 can be sufficiently press-fitted.

[0250] By providing a mechanism for winding and press-fitting the wire harness 49 as described above, it is possible to prevent a situation in which the wire harness 49 is bent and hinders the operation of other mechanisms.

[0251] Note that Fig.25 As shown in FIG. 1A , a fixing portion 77 for fixing a fixed length portion (a portion not wound or pressed) of the wire harness 49 can be formed on the rear side surface of the rear cover 33. Therefore, it is possible to prevent the fixed length portion from bending and hindering the operation of other mechanisms. In addition to these, the specific method for winding and pressing the wire harness 49 is not limited.

[0252] <Other Implementation Methods>

[0253] The present technology is not limited to the above-described embodiments, and various other embodiments can be implemented.

[0254] [Elastic properties of rack]

[0255] Fig.29 is a schematic diagram showing a configuration example of the left rack 5 and the right rack 6 . Fig.29 The state of the head mounted display 1 viewed from the upper side is shown. In this example, the left rack 5 and the right rack 6 are each formed of a metal plate having elastic properties. Specifically, when the head mounted display 1 is worn, the head of the user 2 is slightly tightened so that a secure fit can be obtained during use. In addition, the left strap 7 and the right strap 8 can similarly have elastic properties.

[0256] [Handheld use]

[0257] Fig.30 1 is a schematic diagram showing a state in which the head mounted display 1 is used while being held in the hand. In this way, the user 2 can also bring the head mounted display 1 in the folded state to the eyes to watch a video while holding it in the hand. Therefore, for example, when it is desired to watch a video immediately, when watching for only a short time, etc., the convenience of the user 2 is improved.

[0258] In this case, a configuration is adopted in which the storage position of the rear housing 4 is set at a position that does not hinder the area where the user 2 views the display unit 11. In the present embodiment, when the rear housing 4 is stored, the rear housing 4 is positioned inside the front housing 3. In other words, the rear housing 4 is not positioned between the eyes of the user 2 and the display unit 11, and the rear housing 4 does not hinder the field of vision of the user 2.

[0259] [Automatic power control]

[0260] Fig. 27 and Fig.28 are schematic diagrams each showing a configuration example of a power supply control unit. Fig. 27 A shows a state of the head mounted display 1 in the folded state as viewed from the right side. Fig. 27 B schematically shows the state of the head mounted display 1 in the folded state as viewed from above. The power control unit is provided at Fig. 27 At the square portion in the dotted line shown in , that is, at the center of the front case 3 or the rear case 4 in the left-right direction (X direction).

[0261] Fig.28 Schematic diagram showing the arrangement as viewed from the right Fig. 27In the present embodiment, when the head mounted display 1 is in the folded state, the power control unit turns off the power of the head mounted display 1.

[0262] The power control unit includes a power button 80 and a power lever 81. The power button 80 is arranged on the base plate 35 of the rear housing 4. The power lever 81 includes a base 82 and an abutment 83. The base 82 is a cylindrical member. The abutment 83 is, for example, a plate-like member and is connected to one end of the base 82.

[0263] Fig.28 A shows a state immediately before the head mounted display 1 is completely folded. In other words, it shows a state in which the rear case 4 is positioned slightly above the front case 3. Fig.28 B shows a state in which the head mounted display 1 is completely folded.

[0264] exist Fig.28 In A, the end portion of the base portion 82 that is not connected to the abutment portion 83 ( Fig.28 A) is positioned away from the power button 80. When the head mounted display 1 is completely folded from this state to be set Fig.28 In the state shown in B, the abutment portion 83 contacts the front housing 3 to Fig.28 The left side in B is pressed, and thus the power button 80 is pushed in by the left end portion of the base 82 .

[0265] When the power button 80 is pushed in, the power of the head mounted display 1 is turned off. With such a configuration, a power control unit that automatically turns off the power when folded can be realized. Therefore, the user 2 can save the trouble of turning off the power, and thus the convenience is improved.

[0266] Note that in this embodiment, the portion of the abutment 83 that contacts first and the portion of the front housing 3 are cut obliquely, so that no jamming occurs and folding can be performed smoothly. In addition, a spring is wound around the base 82, and the base 82 and the abutment 83 are operated by the spring that expands and contracts according to the contact between the abutment 83 and the front housing 3.

[0267] Alternatively, a sensor that detects the rotation angle may be provided so that the power is turned off when the rotation angle becomes 0 degrees (in other words, folded state). Alternatively, the power may be turned off when a predetermined time (for example, three seconds) has passed after folding. Conversely, the power may be automatically turned on when the head mounted display 1 is unfolded. In addition to these, the control of the power supply may be performed by any method (for example, a method using a magnetic sensor).

[0268] Note that when assuming Fig.30When the head mounted display 1 is used while hand-held as shown in , a configuration in which automatic power control is not performed can be adopted. In other words, when the head mounted display 1 is folded to be used while hand-held, it is also possible to allow the user to continue watching the video without turning off the power. Conversely, when automatic power control is performed, a configuration that does not assume use while hand-held can also be adopted. In other words, any configuration can be appropriately selected according to the assumed usage mode.

[0269] [Locking mechanism]

[0270] A mechanism for fixing the rear housing 4 so that it cannot move in the folded state may be provided. Specifically, the front housing 3 includes a first protruding portion, and the rear housing 4 includes a second protruding portion, and the first protruding portion and the second protruding portion are in contact with each other when the rear housing 4 is accommodated. In addition, at least one of the first protruding portion or the second protruding portion includes a spring mechanism, and when the rear housing 4 is accommodated, the rear housing 4 is fixed by pressing the spring mechanism.

[0271] In this article, Fig.28 The left half of the front housing 3 shown in FIG. 8 (including the protruding portion of the oblique cut portion) corresponds to the first protruding portion. In addition, the base 82 and the abutment portion 83 correspond to the second protruding portion. In addition, the spring wound on the base 82 corresponds to the spring mechanism.

[0272] In this embodiment, in the folded state ( Fig.28 B), the protruding portion of the front housing 3 and the abutment portion 83 are in contact with each other. In addition, the abutment portion 83 is pressed toward the front housing 3 by the spring wound on the base 82. Therefore, a friction force is generated between the abutment portion 83 and the front housing 3, and thus the abutment portion 83 is difficult to move up and down relative to the front housing 3.

[0273] In other words, it is possible to prevent the rear housing 4 from rotating beyond the folded state, improving the convenience of the user 2. Note that the spring mechanism may be formed only in the protruding portion of the front housing 3, and not in the base 82. Alternatively, the spring mechanism may be formed in both the base 82 and the protruding portion of the front housing 3.

[0274] [Restriction mechanism]

[0275] The rotation angle of the front housing 3 and the rear housing 4 can be limited. Specifically, the hinge includes a limiting mechanism that limits the rotation of the front housing 3 and the rear housing 4 so that the relative rotation angle of the front housing 3 and the rear housing 4 around the hinge does not become equal to or greater than a predetermined angle.

[0276] For example, a hinge such as the left hinge 9 is provided with a stopper mechanism for limiting the rotation angle of the rear housing 4. Fig.18A protruding shape is provided in a portion of the rear belt plate 58 shown in FIG. 1 , and the rotation is restricted so that the leaf spring 59 does not rotate at a predetermined angle or more than a predetermined angle. Therefore, the rotation of the rear housing 4 can be restricted so that the rear housing 4 does not rotate at a predetermined angle or more than a predetermined angle (for example, Fig.19 200 degrees shown in B, etc.).

[0277] If the rotation angle becomes too large (ie, the rear housing 4 is Fig.19 If the cable is rotated too much in the downward direction, the cable may be bent around the hinge and a load may be applied to the cable. By providing a limiting mechanism, the load can be prevented from being applied to the cable. Note that the specific method for limiting the rotation angle is not limited, and any method can be used.

[0278] The respective configurations of the head mounted display, the front housing, the rear housing, the left rack, the right rack, the left belt, the right belt, the left hinge, the right hinge, etc. described with reference to the drawings are merely embodiments and can be arbitrarily modified without departing from the gist of the present technology.
