According to such a configuration, since the plate-like portion having the concave portion is biased by the arm having the convex portion, the click feeling can be surely given to the user, and the arm is moved to the engagement position. Can be reliably maintained.

In the one aspect, the arm has a plurality of the convex portions on the outer peripheral portion, and the plurality of convex portions includes a first convex portion and a second convex portion having a size different from that of the first convex portion, It is preferable to contain.
According to such a configuration, since the plurality of convex portions are provided on the outer peripheral portion, the arm can be maintained at the engaging position at a position where each convex portion and the concave portion are engaged. Moreover, since the magnitude | size of a 1st convex part and a 2nd convex part differs, for example, in the position where a large convex part and a recessed part engage, compared with the position where another convex part and a recessed part engage, The click feeling can be made different. Therefore, it is possible to improve the operational feeling when the arm rotates.

In the one aspect, the arm has a plurality of the convex portions on the outer peripheral portion, and each of the two convex portions of the plurality of convex portions is at both ends of the outer peripheral portion in the rotation range of the arm. Preferably it is formed.
According to such a configuration, the arm can be maintained at each of one end and the other end of the rotation range of the arm. In other words, the image display unit is surely positioned at each of the viewing position where the image display unit supported by the arm is positioned in front of the user's eyes and the retraction position where the image display unit is retracted from the user's eyes. In addition, the arm and the image display unit can be maintained at each position.

  In the one aspect, the mounting unit includes an arrangement unit that is arranged at a position corresponding to the forehead part of the user, and the image display unit corresponds to the left eye and the right eye of the user, respectively. A left side display unit and a right side display unit that are provided so as to be observable by the user, and the arms are respectively positioned on the front side of the placement unit, and the left display unit and the right side display unit The rotating shaft includes a left arm and a right arm that are provided in a pair so as to be rotatable about the rotating shaft along the parallel direction, which is a direction in which the display portions are arranged, and the rotating shaft rotates the left arm.

According to this, the position of the image display unit can be adjusted according to the position of the user's eyes.
Therefore, the convenience of the head-mounted image display device can be improved.

In the one aspect, one of the mounting portion and the arm is in contact with the other, and the image display is performed from an observation position where the user can observe the image displayed by the image display portion. It is preferable to have a restricting part that restricts the part from rotating to the user side.
According to such a structure, it can suppress that the image displayed by the left side display part and the right side display part cannot be observed when the image display part approaches a user too much by the said control part.

In the said one aspect | mode, it is preferable that the said mounting part is mounted | worn with the covering member with which the said user's head is mounted | worn.
Examples of the covering member include members that cover the head, such as a helmet and a hat.
Here, in the head-mounted image display device, when the image display unit is retracted, the amount of movement must be increased if the covering member is attached, and therefore the image display unit can be retracted even when the covering member is attached. A configuration is desired.
According to such a configuration, since the head-mounted image display device is mounted on the covering member, the head-mounted image display device can be used with the covering member mounted.
In addition, since the arm can be prevented from coming into contact with the buttocks of a helmet, a hat, etc., the user can use the image display unit in the head-mounted image display device while wearing the helmet, the hat, etc. Can be moved from the front of the eyes according to the work performed by the user.
Therefore, it is not necessary to remove the head-mounted image display device from the covering member in accordance with each of the visual recognition work and the non-visualization work, so that the work efficiency of the user can be improved.

The distance L1 of the first perpendicular extending to the upper surface 510 of 51 (the surface on the −Y direction side in FIG. 22) is the second extending from the imaginary line to the foremost end of the collar M2 (the part farthest from the user US) It is larger than the perpendicular distance L2. When the upper surface of the image display device 51 is curved, a distance extended by the curvature may be added to the distance L1.
With such a configuration, the pair of arms 6 are moved to the positions shown in FIG. 22 without contacting the collar M2 of the helmet M. Thereby, since the image display device 51 is not positioned in front of the left eye and the right eye of the user US, the virtual image display device 1 can be removed from the helmet M by performing the non-visual operation performed without visually recognizing the image display device 51. It can be executed without removing it.

[Effect of the embodiment]
The virtual image display device 1 according to the present embodiment described above has the following effects.
Even when a user US such as a worker wearing the virtual image display device 1 is wearing a covering member such as a helmet M or a hat, the virtual image display device 1 is attached in a state where the covering member is attached. Even in the state, only the image display unit can be retracted from the front.
Further, the cable 7 connecting the main body 3 and the image display unit 5 is an opening on the mounting unit side provided outside the rotation shaft unit 8 in a front view (when the virtual image display device 1 is viewed from the + Z direction side). The exposed cable 7 is exposed from the portion 3121 to the outside of the main body 3, and the exposed cable 7 is inserted into the arm 6 through the arm-side opening 631. According to this, since at least a part of the cable 7 is accommodated inside the virtual image display device 1, that is, the exposed portion of the cable 7 can be reduced, the arm is used when the user US retracts the image display unit 5. Even if it moves, it can suppress that the said cable gets in the way, or the structure other than the virtual image display apparatus 1 is caught by the said cable.

Since the arm side opening 631 is located outside the mounting part side opening 3121 and below the rotation shaft part 8 when the virtual image display device 1 is viewed from the + Z direction side (front view), When the cable 7 extends in the direction (outside) from the mounting portion side opening 3121 toward the arm side opening 631, it is possible to suppress the cable 7 from being bent or pulled when the arm 6 is rotated. The arrangement of the cable 7 and the rotation of the arm 6 and the image display unit 5 can be performed.
That is, as the arm 6 rotates, the position where the cable 7 starts moving can be placed at the position of the rotation center of the rotation shaft portion 8 (near the position of the center). By making the length of the moving cable 7 approximately the same, it is possible to prevent the cable 7 from being bent or pulled.

  Since the fixing member 632 which fixes the cable 7 which is located in the arm side opening 631 and passes through the arm 6 through the arm side opening 631 is provided, the cable 7 generated by the rotation of the arm 6 is provided. Can be reduced. Therefore, the deterioration of the cable 7 can be suppressed, and the reliability of the virtual image display device 1 can be improved.

  Since the arm 6 is composed of a plurality of arm forming members 6A and 6B combined with each other, for example, a space in which the cable 7 is disposed can be easily formed as compared with a case where the arm 6 is an integrally molded product. Moreover, since the cable 7 is arrange | positioned in the space formed between arm formation member 6A, 6B, when rotating the arm 6, possibility that the user US will touch the cable 7 can be reduced.

  Since the fluid that has entered the arm 6 is discharged to the outside of the arm 6 through the discharge port 6421, it is possible to prevent the fluid from staying in the arm 6. Therefore, the reliability of the virtual image display device 1 can be improved, and the virtual image display device 1 can be used even in an environment where the fluid may enter the arm. Can be improved.

  When the virtual image display device 1 is mounted, the forehead portion HD1 and the back head portion HD2 (positions corresponding to the forehead portion HD1 and the back head portion HD2) can be sandwiched between the main body portion 3 and the band portion 4, respectively. Accordingly, the virtual image display device 1 can be reliably and stably mounted (fixed) on the head HD of the user US.

Here, when the virtual image display device 1 is used outdoors, the possibility of dust and water entering the main body 3 and the image display unit 5 is higher than when the virtual image display device 1 is used indoors. If dust or water enters the main body unit 3 and the image display unit 5, various devices arranged in the main body unit 3 and the image display unit 5 may be deteriorated, and there may be a problem. .
On the other hand, according to such a structure, since the main-body part 3 and the image display part 5 have a waterproof structure, it can suppress that a liquid and dust enter the inside of the main-body part 3 and the image display part 5. FIG. Therefore, it is possible to suppress deterioration of various devices in the main body unit 3 and the image display unit 5, and to operate the virtual image display device 1 more reliably and stably.

  Since the interior case 332 that covers the control board 331 is disposed in the exterior case 31, compared with the case where the control board 331 is disposed directly inside the exterior case 31, the stress acting on the exterior case 31 is increased. Besides being able to be relaxed by the case 332, the control board 331 can be protected even when fluid enters the outer case 31. Therefore, impact resistance and water resistance with respect to the control substrate 331 can be improved, and the virtual image display device 1 can be operated stably.

Since there is a discharge flow path P for discharging a fluid such as water flowing along the inner wall portion 3123 as a pair of ribs located at a portion sandwiching the interior case 332 from the mounting portion side opening 3121 to the outside of the main body portion 3. The dust and water that have flowed into the main body 3 can be discharged out of the main body 3 from the mounting portion side opening 3121. Therefore, it is possible to prevent the control board 331 and the like disposed in the main body 3 from being damaged by the fluid flowing into the main body 3.
Moreover, it can suppress that fluids, such as water, permeate into the image display part 5 with a sealing member. Accordingly, it is possible to suppress damage to various devices and the like arranged in the image display unit.

Here, when the pad 35 connected to the forehead portion HD1 side of the main body 3 is made of a relatively hard material, the pad 35 is not elastically deformed. It may get worse. Similarly, the same applies when the band portion 4 is made of a relatively hard material.
On the other hand, according to the present embodiment, when the virtual image display device 1 is mounted, the pad 35 and the band portion 4 are elastically deformed, so that the forehead portion HD1 and the back head portion HD2 (the forehead portion HD1 and the back head portion HD2) The front forehead portion HD1 and the back head portion HD2 can be clamped while applying an appropriate pressure to the position corresponding to each of the head portion HD1. Therefore, the wearability of the virtual image display device 1 can be further improved.

  In the present embodiment, the arm 6 can be reliably rotated with respect to the main body 3 around the screw 811 of the rotation shaft 8. When the arm 6 rotates, the sandwiched member 82 that comes into contact with the arm 6 has smoothness, so that the arm 6 can be smoothly rotated. Therefore, the user US can easily perform the rotation operation of the arm 6.

  Since the convex portions 623 and 624 provided in the outer peripheral portion 622 are engaged with the concave portion 8211 provided in the plate-like portion 821, when the convex portions 623 and 624 are fitted (engaged) into the concave portion 8211, A click feeling (operation feeling caused by the user US feeling that the convex portions 623 and 624 fit into the concave portion 8211) can be given to the user US. In addition, the position of the arm 6 with respect to the main body 3 can be easily maintained at the position where the convex portions 623 and 624 and the concave portion 8211 are engaged. Moreover, since the to-be-clamped member 82 has smoothness, the said convex part 623,624 can be engaged with the said recessed part 8211 more smoothly.

  Since the plate-like portion 821 having the concave portion 8211 is urged by the outer peripheral portion 622 of the arm 6 having the convex portions 623 and 624, the click feeling can be surely given to the user US, and the arm 6 can be connected to these members. It can be easily maintained reliably at the joint position.

  Since each of the convex portions 623 and 624 is formed at both ends in the rotation range of the arm 6 of the outer peripheral portion 622, the arm 6 can be maintained at each of one end and the other end side of the rotation range of the arm 6. . In other words, each of the image display unit 5 supported by the arm 6 includes a visual recognition position where the image display unit 5 is positioned in front of the user's eyes and a retreat position where the image display unit 5 is retracted from the user's eyes. The arm 6 and the image display unit 5 can be maintained at each position.

  The left-eye image display device 51L and the left-arm image display device 51L that support the left-eye image display device 51L and the right-eye image display device 51R that are provided according to the left eye and the right eye of the user US are respectively provided. In addition, the left arm 6L and the right arm are configured to be rotatable about the left pivot shaft 8L and the right pivot shaft 8R along the parallel direction (+ X direction) in which the right-eye image display devices 51R are arranged. By rotating 6R along the left rotation shaft 8L and the right rotation shaft 8R, the image display unit 5 can be moved away from the user's eyes. For this reason, since the left arm 6L and the right arm 6R rotate around the left rotation shaft portion 8L and the right rotation shaft portion 8R, the virtual image display device 1 is used by the user US when performing a non-visual operation. The image display unit 5 can be retracted from the front without being removed from the position corresponding to the head HD. That is, the retraction amount of the image display unit 5 can be enlarged. Accordingly, the virtual image display device 1 is removed regardless of whether the user US performs a visual operation for visually recognizing the image display unit 5 or a non-visual operation in which the user US does not visually recognize the image display unit 5. Since labor can be saved, work efficiency can be improved.

  Further, since each of the left arm 6L and the right arm 6R is supported by the left rotation shaft portion 8L and the right rotation shaft portion 8R, for example, each of the left arm 6L and the right arm 6R has one rotation shaft portion. The left-eye image display device 51L and the right-eye image display device 51R supported by the left arm 6L and the right arm 6R, respectively, can be reliably rotated as compared to the case where the left-arm 6L and the right-arm 6R are supported.

Here, when the rotation shaft portion 8 is provided on the inner periphery of the main body portion 3, or the rotation shaft portion 8 is provided on the outer periphery of the main body portion and provided at both ends of the main body portion 3. The left and right pivot shafts 8L and 8R are provided in the main body 3 for retracting the collar M2 of the helmet M in accordance with the shape of the forehead of the user US and the helmet M. For this purpose, it is necessary to extend the main body 3 to both ends in the parallel direction (the direction along the + X direction). For this reason, the virtual image display device 1 is increased in size.
On the other hand, according to the present embodiment, the left rotation shaft portion 8L and the right rotation shaft portion 8R are provided on a surface different from the surface facing the forehead portion HD1 in the main body 3 and in the + Z direction. Since it is located inside the both ends of the main body 3 when viewed from the side, the pivot shafts 8L and 8R can be provided without extending the main body 3 to both ends in the parallel direction. . Therefore, the virtual image display device 1 can be reduced in size.

Since each of the left rotation shaft portion 8L and the right rotation shaft portion 8R is supported by the bottom portion (the outer surface 312B of the lower case 312), for example, the left rotation shaft portion 8L and the right rotation shaft portion. Compared with the case where 8R is supported on the surface on the opposite side to the user of the main body 3, the image display unit 5 supported by the left arm 6L and the right arm 6R can be stably held.
Further, for example, the left rotation shaft portion 8L and the right rotation shaft portion 8R are compared to the case where the left rotation shaft portion 8R and the right rotation shaft portion 8R are supported by the upper surface 3113 located on the opposite side to the bottom surface portion (the outer surface 312B of the lower case 312). Thus, the rotation range of the left arm 6L and the right arm 6R can be reduced, and the length of the arm 6 can be reduced. Therefore, the virtual image display device 1 can be reduced in size.

The left second extension 64L is connected to the left end of the left-eye image display device 51L, that is, the end opposite to the user US, and the right second extension 64R is the right-eye image. Since the display device 51R is connected to the right end portion, that is, the end portion on the opposite side to the user US, the left second extension portion 64L and the right second extension portion 64R display the left eye image. The left-eye image display device 51L and the right-eye image display device 51R can be stably held as compared with the case where they are connected to the end portions on the user side of the device 51L and the right-eye image display device 51R.
Further, for example, when the user US wears a covering member such as the helmet M on the head HD, the left second extension 64L and the right second extension 64R include the left-eye image display device 51L and When connected to the end portion on the user US side of the right-eye image display device 51R, the left second extending portion 64L and the right second extending portion 64R come into contact with the buttocks M2 and the like of the helmet M, There is a possibility that the left-eye image display device 51L and the right-eye image display device 51R cannot be retracted from the eyes of the user US.
On the other hand, according to the present embodiment, the left second extending portion 64L and the right second extending portion 64R are opposite to the user US of the left eye image display device 51L and the right eye image display device 51R. Since the left second extended portion 64L and the right second extended portion 64R do not contact the flange M2, the left eye image display device 51L and the right eye image are connected. Each of the display devices 51R can be reliably retracted from the front of the user US.

The slide mechanism 65 allows the image display unit 5 to slide in a direction in which the image display unit 5 is in contact with or separated from the main body unit 3, so that the distance between the main body unit 3 and the image display unit 5 can be adjusted. According to this, the position of the image display part 5 can be adjusted according to the position of the eyes of the user US.
Therefore, the convenience of the virtual image display device 1 can be improved.

  When the image display unit 5 is too close to the user US by the first connection unit 61, the second connection unit 62, and the outer surface 312B of the lower case 312 that function as the restriction unit, the left-eye image display device 51L and the right It can suppress that the image displayed by the image display apparatus 51R for eyes cannot be observed.

Here, in the virtual image display device 1, when the image display unit 5 is retracted, if the helmet M or the like is attached as a covering member, the amount of movement must be increased. A possible configuration is desired.
According to this embodiment, since the virtual image display device 1 is attached to the helmet M, the virtual image display device 1 can be used with the helmet M attached.
In addition, since the arm 6 can be prevented from coming into contact with the helmet M2 such as the helmet M and the hat, the user US can wear the image on the virtual image display device 1 while wearing the helmet M and the hat. The display unit 5 can be moved from the front according to the operation performed by the user US.
Therefore, since it is not necessary to remove the virtual image display device 1 from the helmet M according to each of the visual recognition work and the non-visualization work, the work efficiency of the user US can be improved.

Even in this case, it is sufficient that a space through which the cable 7 is inserted is formed in the arm 6.
Moreover, in the said embodiment, the arm 6 was comprised by the two arm formation members of the arm formation members 6A and 6B combined together. However, the present invention is not limited to this. For example, the arm 6 may be configured by combining three or more arm forming members, and the cable 7 is formed in a space formed between two arm forming members among the three or more arm forming members. The cable 7 may be disposed in a space formed between the three arm forming members.

In the above embodiment, in the arm 6, the discharge port 6421 of the second extending portion 64 is positioned on the surface on the −Y direction side of the L-shaped portion 642. However, the present invention is not limited to this. The discharge port 6421 is not limited to the above position, and may be located at a position facing the heel portion M2 of the helmet M, for example. That is, as long as the fluid discharged from the discharge port 6421 does not reach the user US, it may be located at any part.
For example, the discharge port 6421 may not be provided. Even in this case, the fluid that has entered the space of the arm 6 can be discharged from the arm-side opening 631 by rotating the arm 6.
In the above embodiment, the arm side opening 631 is provided at the position shown in FIG. However, the present invention is not limited to this. For example, the arm-side opening 631 may be positioned closer to the center of the face of the user US than the pivot shaft 8 when the virtual image display device 1 is viewed from the + Z direction side. Even in this case, in addition to the same effects as the above embodiment, it is possible to suppress the fluid discharged from the arm side opening 631 from being applied to the user US. That is, the arm-side opening 631 may be located at any position as long as the fluid discharged from the arm-side opening 631 does not reach the user US.

  In the above embodiment, the second connecting portion 62 of the arm 6 has convex portions 623 and 624 formed on the outer peripheral portion 622 centered on the rotating shaft portion 8, and these convex portions 623 and 624 are the arms of the outer peripheral portion 622. It was decided that it was formed at both ends in the 6 rotation range. However, the present invention is not limited to this. For example, only one of the convex portions 623 and 624 may be formed. Even in this case, when at least one of the convex portions 623 fits into the concave portion 8211, it is possible to give a click feeling to the user and to maintain the arm 6 at the engagement position. The second connection unit 62 may have the following configuration.
