The bracket connecting portion 56 with respect to 70 is held at a predetermined rotation angle.

(Motor unit)
As shown in FIG. 10, the motor unit 92 includes a hinge motor 94, a motor case 96, and a motor cover 98. The hinge motor 94 has a motor output shaft 94A extending in the lateral width direction of the display unit 14. The hinge motor 94 is, for example, a stepping motor, and is connected to the above-described control board 42 (see FIG. 5) via the cable 100.

  The motor output shaft 94A is disposed on the same axis as the first connection bolt 80 and the second connection bolt 86 (see FIG. 9). A sun gear 112 of a planetary gear mechanism 110 described later is attached to the motor output shaft 94A. The hinge motor 94 is disposed between the pair of first connection wall portions 56 </ b> A and the second connection wall portions 56 </ b> B while being accommodated in the motor case 96.

(Planetary gear mechanism)
As shown in FIG. 12, the planetary gear mechanism 110 is attached to the inner wall surface of the first connecting wall portion 56A. The planetary gear mechanism 110 is an example of a speed reduction mechanism that decelerates the rotational output (driving force) of the hinge motor 94. The planetary gear mechanism 110 includes a sun gear 112 (see FIG. 10), a ring gear 114, and a planetary pinion 116.

  As shown in FIG. 10, the sun gear 112 is attached to the motor output shaft 94 </ b> A of the hinge motor 94. The sun gear 112 has a plurality of teeth on the outer periphery. As shown in FIG. 12, the ring gear 114 is formed in a ring shape. The ring gear 114 has a plurality of teeth on the inner peripheral portion. The ring gear 114 is disposed coaxially with the motor output shaft 94A, and is fixed to the inner wall surface of the first connecting wall portion 56A by a plurality of screws 118. The ring gear 114 is fixed to the inner wall surface of the first connecting wall portion 56A via a plurality of sleeve spacers 120.

  The planetary pinion 116 is rotatably attached to a shaft pin 122 that protrudes from the inner wall surface of the first connecting wall portion 56A to the inside of the ring gear 114. The planetary pinion 116 has a plurality of teeth on the outer periphery. As shown in FIG. 13, the planetary pinion 116 is disposed inside the ring gear 114 and meshed with both the ring gear 114 and the sun gear 112.

  When the hinge motor 94 fixed to the stand bracket 70 is operated, the motor output shaft 94A and the sun gear 112 are integrally rotated in a predetermined direction. As a result, the ring gear 114 is rotated integrally with the hinge bracket 52 via the planetary pinion 116. As a result, as shown in FIG. 14, the hinge bracket 52 rotates with respect to the stand bracket 70 about the central axis C of the first connection bolt 80 and the second connection bolt 86.

  At this time, the rotational output of the hinge motor 94 is decelerated by the planetary gear mechanism 110 and transmitted to the hinge bracket 52. The reduction ratio of the planetary gear mechanism 110 is represented by the number of teeth of-(the number of teeth of the sun gear 112 / the ring gear 114). When the motor output shaft 94A is rotated in the reverse direction, the hinge bracket 52 rotates in the reverse direction with respect to the stand bracket 70.

(stand)
As shown in FIG. 3, the stand 130 includes a pedestal part 132, an arm part 134, and a cover 136. The pedestal portion 132 is formed in a plate shape and is installed on an installation surface such as a desk (not shown). The arm part 134 is raised from the rear end part of the pedestal part 132, and the upper part is gently curved forward. An attachment portion 134A is provided at the upper end portion of the arm portion 134.

  The attachment portion 134A is formed in a plate shape. The attachment portion 134A is fixed to the base portion 72 with screws or the like (not shown) in a state where the attachment portion 134A is superimposed on the rear surface 72R (see FIG. 9) of the base portion 72 of the stand bracket 70. A cover 136 is attached to the rear surface of the attachment portion 134A.

(Tilt control unit)
As shown in FIG. 15, the tilt control unit 140 controls the above-described hinge motor 94 based on the image information input from the camera 36, and the tilt angle of the display device 14 according to the position of the user's pupil. θ (see FIG. 6) is adjusted. The tilt control unit 140 is realized as a computer including a CPU, a memory, a storage unit, and the like, for example.

  The storage unit is, for example, an HDD (Hard Disk Drive) or a flash memory. The storage unit stores a control program for controlling a hinge motor 94 described later. Then, the CPU reads the control program from the storage unit, expands it in the memory, and executes each step of the control program.

  The tilt control unit 140 includes an image processing unit 142, a tilt angle calculation unit 144, and a motor control unit 146. The functions of the image processing unit 142, the tilt angle calculation unit 144, and the motor control unit 146 will be described later together with the operation of the tilt control unit 140.

  Next, the operation of the tilt control unit will be described. In the following description, each step of the control program executed by the tilt control unit 140 is referred to FIG.

  When the electronic device 10 is turned on by a user in front of the display device 14, the following occurs. That is, in step S <b> 1, the infrared irradiator 34 radiates infrared rays radially to the user's face from the irradiation hole 38 formed in the lower end portion of the front cover 18.

  Next, in step S <b> 2, infrared rays reflected by the user's pupil are photographed by the camera 36. The camera 36 outputs the captured image information to the image processing unit 142 of the tilt control unit 140. The image processing unit 142 calculates the position of the user's pupil from the image information input from the camera 36. Then, the image processing unit 142 outputs the calculated pupil position information to the tilt angle calculation unit 144.

  Next, in step S <b> 3, the tilt angle calculation unit 144 is based on the pupil position information input from the image processing unit 142, and the tilt angle of the display device 14 in which the display surface 14 </ b> A faces the user's face (pupil) side. θ (see FIG. 6) is calculated. Then, the tilt angle calculation unit 144 outputs the calculated tilt angle θ 1 to the motor control unit 146.

  Next, in step S <b> 4, the motor control unit 146 calculates the rotation amount of the hinge motor 94 from the difference between the tilt angle θ input from the tilt angle calculation unit 144 and the current tilt angle θ of the display unit 14. In step S5, the motor control unit 146 operates the hinge motor 94 based on the calculated rotation amount of the hinge motor 94, and rotates the motor output shaft 94A of the hinge motor 94 by a predetermined amount.

  As a result, the sun gear 112 is rotated in the same direction as the motor output shaft 94A. For example, as shown in FIG. 13, when the sun gear 112 is rotated in the direction of arrow a, the ring gear 114 is rotated integrally with the hinge bracket 52 (in the direction of arrow b) via the planetary pinion 116. As a result, as shown in FIG. 14, the hinge bracket 52 is rotated about the central axis C of the first connection bolt 80 and the second connection bolt 86 with respect to the stand bracket 70, and the display surface 14 </ b> A of the display 14 is displayed. (See FIG. 6) is directed to the user's face.

  Note that the tilt control unit 140 may be configured to repeatedly execute steps S1 to S5.

  Next, the effect of this embodiment will be described.

  First, the hinge unit 150 according to the comparative example will be described. As shown in FIG. 17, in the hinge unit 150 according to the comparative example, the base portion 54 of the hinge bracket 52 is fixed to the rear surface 24 </ b> R of the panel frame 24.

In this case, as shown in FIG. 18, since the panel frame 24 is interposed between the indicator 14 and the hinge bracket 52, the indicator 14, the first connecting bolt 80, and the second connecting bolt 86 are viewed from the side. The distance L _{0 from the} central axis C is increased. Therefore, it is difficult to bring the central axes C of the first connection bolt 80 and the second connection bolt 86 close to the position of the center of gravity G (see FIG. 6) of the display device 12 in a side view.

  Then, when the center of gravity G of the display device 12 and the center axis C of the first connection bolt 80 and the second connection bolt 86 are deviated from a side view, a moment due to the weight of the display device 12 is constantly generated. This makes it difficult for the display device 12 to rotate with respect to the stand 130. That is, it becomes difficult to adjust the tilt angle θ 1 of the display device 12.

  On the other hand, in this embodiment, as shown in FIG. 19, the base portion 54 of the hinge bracket 52 is fixed to the front surface 24 </ b> F of the panel frame 24. Further, the bracket connecting portion 56 of the hinge bracket 52 extends to the rear side of the panel frame 24 through an insertion hole 60 formed in the panel frame 24. The stand bracket 70 is connected to the bracket connecting portion 56 via the first connecting bolt 80 and the second connecting bolt 86.

Thus, in the present embodiment, the base portion 54 of the hinge bracket 52 is fixed to the front surface 24F of the panel frame 24. Therefore, as shown in FIG. 20, in the present embodiment, the display unit 14 and the first connection bolt 80 and the central axis C of the second connection bolt 86 are more side-viewed than the hinge unit 150 according to the comparative example. distance L ₁ is narrowed _(L 1 _<L 0).

  Therefore, the center axis C of the first connecting bolt 80 can be easily brought close to the center of gravity G of the display device 12. In other words, in this embodiment, it becomes easy to set the center of gravity G of the display device 12 on the central axis C of the first connection bolt 80 and the second connection bolt 86.

  And if the gravity center G of the display apparatus 12 is located on the central axis C of the 1st connection bolt 80 and the 2nd connection bolt 86, generation | occurrence | production of the moment resulting from the weight of the display apparatus 12 will be suppressed. As a result, the display device 12 can be easily rotated with respect to the stand 130, and the tilt angle θ 1 can be easily adjusted. As a result, the power consumption of the hinge motor 94 is reduced.

  The base portion 54 is provided with a reinforcing arm portion 54B. Thereby, the fixing strength of the hinge bracket 52 to the panel frame 24 is increased. Further, the plurality of reinforcing arm portions 54 </ b> B are arranged along diagonal lines of the display 14 and the panel frame 24. Thereby, the torsional rigidity of the display 14 and the panel frame 24 is increased. Therefore, the durability of the display device 14 is improved.

  In particular, the control board 42, the storage device unit 48, and the like are attached to the rear surface 24R side of the panel frame 24, and are not attached to the front surface 24F of the panel frame 24. That is, the front surface 24F of the panel frame 24 is less obstructed by the reinforcing arm portion 54B than the rear surface 24R. Therefore, the front surface 24F of the panel frame 24 can be reinforced over a wide range by the reinforcing arm portion 54B.

  Thus, in this embodiment, while reinforcing the panel frame 24, the center axis C of the 1st connection bolt 80 and the 2nd connection bolt 86 is brought close to the indicator 14, and the center of gravity G of the display device 12 is placed on the center axis C. Can be positioned.

  Further, the head portion 80B of the first connection bolt 80 and the head portion 86B of the second connection bolt 86 are disposed between the pair of first connection wall portions 56A and the second connection wall portion 56B (inside). And the 1st spring washer 82, the 1st nut 84, the 2nd spring washer 88, and the 2nd nut 90 are arranged on the outside of a pair of the 1st connecting wall part 56A and the 2nd connecting wall part 56B.

  Therefore, in the present embodiment, the pair of first couplings is compared with the configuration in which the first nut 84 and the second nut 90 are disposed between the pair of first coupling wall portions 56A and the second coupling wall portion 56B. The accommodation space between the wall portion 56A and the second connecting wall portion 56B becomes wider.
