As shown in FIG. 2, the head-mounted device in a state in which the photographing display unit 100 and the handheld unit 300 are combined is referred to as a handheld mode B in the present embodiment.

  In the handheld mode B, the user can observe the display of the photographing display unit 100 by gripping the handheld unit 300 and bringing the photographing display unit 100 and the face into close contact with each other. As in the head-mounted mode A, the photographing display unit 100 and the handheld unit 300 are detachably coupled.

  In the present embodiment, the photographing display unit 100 and the head mounting unit 200 are removable. Similarly, the photographing display unit 100 and the handheld unit 300 can be attached and detached. Since a common mechanism is provided in the connecting portion, when a plurality of users take turns using the photographing display section 100, it is possible to easily take turns by simply detaching from the head mounting section 200 or the handheld section 300. Is. Further, if a common color or a symbol is given to the joint portion in advance, the user can perform a smooth replacement work without hesitation. Furthermore, if a plurality of head mounting portions 200 are prepared in advance and adjustment is performed according to the size of the head of each user, it is necessary to adjust the tightening of the head mounting portion 200 at every change. Nor. Therefore, according to this embodiment, when a plurality of users use the head mounting device in alternation, the alternation work can be facilitated. Next, a specific structure and mechanism for realizing the head mounting device according to the present embodiment will be described.

  FIG. 3A is a perspective view of the photographing display unit 100 of the head-mounted device according to this embodiment. As shown in the figure, the photographing display unit 100 includes a front cover 140, a rear cover 120, and a cable 150. In addition, the photographing display unit 100 also includes a photographing unit (not shown).

  The front cover 140 is formed of a transparent or translucent member. The photographing unit photographs the real space in front of the photographing unit via the front cover 140 and acquires a real space image. When an opaque member is used for the front cover 140, it is possible to shoot by making a hole in front of the shooting unit.

  The cable 150 is used for supplying power to the photographing display unit and for data communication with the outside. If the photographing display unit 100 includes a battery having a sufficient capacity to realize each function, an arithmetic circuit having an arithmetic performance sufficient for image processing, a wireless communication device, etc., the cable 150 can be omitted. I can.

  FIG. 3B is a perspective view of the photographing display unit 100 from a viewpoint different from that in FIG.

  As illustrated, the display unit 110, the rear cover 120, the first coupling unit 130, and the like are included. In addition, the first coupling portion 130 includes a first rail 131, a first support surface 132, and a first pawl engaging portion 133.

  Similarly to the front cover 140, the rear cover 120 is also formed of a transparent or translucent member or a member having a hole. The user can observe the display on the display unit 110 through the rear cover 120. Further, the display unit 110 includes not only a display device which is a display surface of an image but also a projection optical system, a reflection optical system, and the like.

  Although the specific function will be described later, the first coupling unit 130 is used to couple the photographing display unit 100 with the head mounting unit 200 or the handheld unit 300.

  FIG. 4A is a perspective view of the head mounting portion 200 in the head mounting mode A state. As shown in the figure, the head mounting portion 200 includes a second coupling portion 210, an outer belt 220 and an inner belt 221, a occipital region supporting portion 230, a frontal region supporting portion 240, and the like.

  As described above, the photographing display unit 100 and the head mounting unit 200 in this embodiment can be attached and detached. With reference to FIG. 4, specific operations and mechanisms for coupling and separating the photographing display unit 100 and the head mounting unit 200 in this embodiment will be described.

  The second coupling portion 210 is composed of a second rail 211, a second support surface 212, a second lever 213, and a second claw 214. First, the user carries the photographing display unit 100 above the head mounting unit 200 so that the first rail 131 is located above the second rail 211. Then, the photographing display unit 100 is lowered while pressing the first rail 131 against the second coupling unit 210 side. Then, the first rail 131 and the second rail 211 mesh with each other. The second claw 214 is itself an elastic member, or receives a force from another elastic member and is elastically deformably supported. When the photographing display unit 100 is further lowered in a state where the first rail 131 and the second rail 211 are meshed with each other, the second claw 214 is pushed by the first coupling portion 130 toward the frontal support portion 240 side. When the photographing display unit 100 is further lowered while the second claw 214 is pushed away, the first support surface 132 and the second support surface 212 come into contact with each other. At that moment, the displaced second pawl 214 enters the space above the first pawl engaging portion 133 by the restoring force. FIG. 4B is a side sectional view showing the positions of the first supporting surface 132, the second supporting surface 212, the second claw 214, and the first claw engaging portion 133 in this state. On the other hand, the second claw 214 and the first claw engaging portion 133 are provided with an inclination in a direction in which they mesh with each other. Even if the photographing display unit 100 is to be detached from the head mounting unit 200, it cannot be detached due to the engagement of the first rail 131 and the second rail 211, and the second pawl 214 and the first pawl engaging portion 133 (latch mechanism). By the above operation, the photographing display unit 100 and the head mounting unit 200 can be connected.

  Next, when the photographing display unit 100 and the head mounting unit 200 are separated, the second lever 213 is used. When the second lever 213 is moved in the i direction of FIG. 4B, the second claw 214 comes out of the space above the first claw engaging portion 133. In this state, if the photographing display section 100 is moved above the head mounting section 200, the second claw 214 and the first claw engaging section 133 do not mesh with each other. Therefore, the photographing display unit 100 moves upward while being guided by the first rail 131 and the second rail 211. If the movement is continued, the first rail 131 and the second rail 211 are separated. By the above operation, the photographing display unit 100 and the head mounting unit 200 can be separated.

  Next, an operation in which the user mounts or dismounts the head mounting unit 200 on the head will be described.

  The user puts his/her head in the space inside the second coupling section 210, the outer belt 220, the inner belt 221, and the occipital support section 230. When the head hits the frontal support section 240, the outer belt 220 and the inner belt 221 are operated as the adjusting section. A part of the inner belt 221 is inserted inside the outer belt 220. The inner belt 221 is further inserted into the outer belt 220 when a force is applied to the finger grips 222a and 222b so as to approach each other. Here, the outer belt 220 includes a retaining mechanism 223. The retaining mechanism 223 may have a structure in which a claw is applied to a groove or a hole provided in the inner belt 221. The retaining mechanism 223 prevents the inner belt 221 from moving away from the outer belt 220. The same is true even if a force for separating fingers from each other is applied to the fingers 222. By the retaining mechanism 223, the head mounting portion 200 is firmly positioned without being loosened unexpectedly during head mounting. By the above operation, the user can mount the head mounting portion 200 on the head.

  On the other hand, the retaining mechanism 223 can release the retaining mechanism by a predetermined operation. When the retainer of the retaining mechanism 223 is released by a predetermined operation, the inner belt 221 is pulled out from the outer belt 220 by the reaction force of tightening. As a result, the tightening of the head mounting system is loosened. The user exits the head from the space inside the second coupling portion 210, the outer belt 220, the inner belt 221, and the occipital region support portion 230. By the above operation, the user can remove the head mounting portion 200 from the head.

  FIG. 4C is a perspective view of the head mounting portion 200 in the head mounting mode A from a viewpoint different from that in FIG. 4A. The second elastic member 250 is provided on the side of the second joint portion 210, the outer belt 220, the occipital region support portion 230, and the frontal region support portion 240 that abuts on the head. Due to the elasticity of the second elastic member 250, the concentration of pressure when the head is worn is relieved, and the wearing feeling of the user is improved.

  FIG. 5A is a perspective view of the handheld unit 300 in the handheld mode B state. The handheld part 300 includes a third coupling part 310 and a grip part 320. The third coupling part 310 includes a third rail 311, a third support surface 312, a third lever 313, and a third claw 314. The operation of connecting and disconnecting the image capturing display unit 100 and the handheld unit 300 is substantially the same as the operation of connecting and disconnecting the image capturing display unit 100 and the head mounting unit 200.

  FIG. 5B is a perspective view of the handheld unit 300 in the handheld mode B from a viewpoint different from that of FIG. 5A. The third elastic member 330 is provided on the side of the third joint 310 that contacts the head. When looking into the display 110 built in the photographing display unit 100, the user presses the vicinity of the forehead against the third elastic member 330. Due to the elasticity of the third elastic member 330, the concentration of pressure on the forehead is relieved. If the grip 320 is supported by both hands or one hand and the third elastic member 330 is supported by the forehead at the same time, the position of the head and the photographing display unit 100 is less likely to shift.

  With reference to FIG. 6, a mechanism for preventing the photographing display unit and the head mounting unit from being separated during mounting will be described. The method of coupling and separating the photographing display unit 100 and the head mounting unit 201 is substantially the same as that of the photographing display unit 100 and the head mounting unit 200.

  FIG. 6A is a side sectional view of the head mounting portion 201 when the head is mounted. As shown in the figure, it is composed of a second coupling portion 210, an outer belt 220, and a frontal support portion 240. The second coupling part 210 includes a second rail 211, a second support surface 212, a second lever 213, and a second claw 214. The frontal support 240 has a rotation shaft 241. The rotary shaft 241 holds the frontal support 240 at an arbitrary angle, or applies a force in the opposite direction ii of FIG. 6A to the frontal support 240. When a force greater than a predetermined value is applied from the user's head, the frontal support 240 moves away in the ii direction of FIG. 6A. When the head is attached, the frontal support 240 is pushed away by the user's head in the ii direction in FIG. 6A. The gap between the second lever 213 and the frontal support 240 in this state is called the head-mounted gap g1.

  When the second lever 213 is pushed in the i direction of FIG. 6A to separate the photographing display unit 100 from the head mounting unit 201, the head mounting gap g1 is narrowed. However, even if the clearance g1 when the head is mounted is narrowed, the second claw 214 cannot be removed from the space above the first claw engaging portion 133. The same is true even if the size and shape of the user's head vary within the normally assumed range. That is, when the head is mounted, by suppressing the release of the coupling of the latch mechanism described above, the photographing display unit 100 and the head mounting unit 201 can be prevented from being separated from each other.

  The frontal support portion 240 pushed away by the user's head during wearing can be moved in the opposite direction ii in FIG. 6A by the external force of the user during non-head wearing. FIG. 6B is a side sectional view of the head mounting portion 201 after the frontal support portion 240 is moved. The gap between the second lever 213 and the frontal support 240 in this state is referred to as a non-head mounting gap g2. If the size and shape of the user's head are within the normal expected range, the head mounting portion 201 is not mounted in this state. Further, the relationship that the clearance when the head is mounted g1<the clearance when the head is not mounted g2 is established.

  Since the photographing display unit 100 is separated from the head mounting unit 201, when the second lever 213 is pushed in the iii direction in FIG. 6B, the non-head mounting gap g2 is narrowed. When the clearance g2 when the head is not attached is narrowed, the second claw 214 comes out of the space above the first claw engaging portion 133. That is, when not wearing the head, the photographing display unit 100 and the head wearing unit 201 can be separated.

  The head mounting unit 201 cannot separate the photographing display unit 100 and the head mounting unit 201 when the head is mounted, and can separate the photographing display unit 100 and the head mounting unit 201 when the head is not mounted. Therefore, the head mounting unit 201 can prevent the photographing display unit and the head mounting unit from being unintended by the user when the head is mounted.

  The electrical contacts of the photographing display unit 102 and the head mounting unit 202 will be described with reference to FIG. 7. The method of coupling and separating the photographing display unit 102 and the head mounting unit 202 is substantially the same as that of the photographing display unit 100 and the head mounting unit 200.

  FIG. 7A is a perspective view of the photographing display unit 102. The photographing display unit 102 includes a first coupling unit 130, and the first coupling unit 130 further includes a first electrical contact 134.

  FIG. 7B is a perspective view of the head mounting portion 202. The head mounting part 202 includes a second coupling part 210, and the second coupling part 210 further includes a second electrical contact 215.

  When the photographing display unit 102 and the head mounting unit 202 are coupled via the first coupling unit 130 and the second coupling unit 210, the first electrical contact 134 and the second electrical contact 215 come into contact with each other. Due to the contact between the first electrical contact 134 and the second electrical contact 215, the photographing display unit 102 and the head mounting unit 202 can supply or communicate with each other. For example, batteries that drive the photographing display unit 102 can be installed in the head mounting unit 202. Alternatively, switches for operating the photographing display unit 102 can be installed in the head mounting unit 202. Even if the handheld portion 300 is provided with an electrical contact, substantially the same function can be realized.
