  9 and 10 are diagrams for explaining the rotation operation of the display device turntable of FIG. With reference to FIG.1, FIG.2, FIG.4, FIG.5 and FIG. 7 to FIG. 10, the horizontal rotation operation | movement in the horizontal surface of the display apparatus turntable 20 is demonstrated.

  First, as shown in FIG. 4, the display unit support member 51 is perpendicular to the rotating plate 31 and faces the front (the central portion of the rotating gear portion 48 a of the rotating gear member 48 is the small-diameter gear portion of the gear 45. 45b), the user presses an auto-turn button (not shown) of an attached remote controller (not shown) to move the display body 10 (see FIG. 1) to the right (arrow A direction). A signal to be rotated is transmitted to a control circuit unit (not shown) of the display body 10. Based on this signal, the stepping motor 42 of the display device turntable 20 is driven.

  Specifically, as shown in FIG. 4, as the stepping motor 42 is driven, the worm gear 47 attached to the stepping motor 42 is rotated in the direction of arrow E1 (see FIG. 7), and the gear 43 is It is rotated in the direction of arrow E2 (see FIG. 7). Then, the driving side gear 62 of the torque limiter 60 is rotated in the arrow E3 direction via the gear 43. Then, the driven gear 61 of the torque limiter 60 is rotated in the arrow E3 direction, and the gear 44 is rotated in the arrow E4 direction (see FIG. 7). Further, when the gear 45 is rotated in the direction of arrow E5 (see FIG. 7), the rotary gear member 48 is rotated in the direction of arrow E6.

  As a result, as shown in FIG. 9, the rotating plate 31 on the rotating unit 30 to which the display unit support member 51 is attached starts rotating in the direction of the arrow G1, so that the display body 10 (see FIG. 1) Start rotation in direction A (see FIG. 1).

  9, the rotating plate 31 on the rotating unit 30 on which the display main body 10 (see FIG. 1) is placed continues to rotate in the direction of arrow A (see FIG. 1) at a predetermined rotation speed. . At this time, the rotating plate 31 rotates in a state of receiving a load of the display main body 10 (see FIG. 1).

  When the display main body 10 is rotated to an angle desired by the user, the user releases the auto-turn button (not shown) of the attached remote controller (not shown), thereby causing the display main body 10 (FIG. 1). The signal for rotating the reference (refer to the arrow A direction in FIG. 1) is not transmitted to the control circuit unit (not shown) of the display body 10. Accordingly, the driving of the stepping motor 42 is stopped. As a result, the rotating plate 31 stops at a position as shown in FIG. 9 and stops rotating in the direction of the arrow G1.

  Further, in a state where the rotation operation of the display main body 10 (see FIG. 1) in the direction of arrow A (see FIG. 1) is continued by the user, the rotation angle of the rotating plate 31 is maximum (30 degrees in the present embodiment). In this case, the rotating plate 31 is in contact with a stopper member (not shown) provided inside the rotating unit 30, so that the rotation operation in the direction of arrow A (see FIG. 1) is restricted. Therefore, the rotating plate 31 stops at a position as shown in FIG. 10 and stops rotating in the direction of the arrow G1. At this time, since the stepping motor 42 continues to be driven, the driving torque transmitted from the stepping motor 42 is transmitted to the driving side gear 62 of the torque limiter 60 through the worm gear 47 and the gear 43.

  As shown in FIG. 8, since the driven gear 61 is pressed against the driving gear 62 with a biasing force set in advance by the spring member 63, the driven gear 61 associated with the pressing force of the spring member 63 is used. When a driving torque greater than the frictional force between the outer peripheral surface of the driving side gear 62 and the inner peripheral surface of the driving side gear 62 is generated on the driving side gear 62, the inner peripheral surface of the driving side gear 62 and the outer periphery of the driven side gear 61 The driving torque of the driving side gear 62 is not transmitted to the driven side gear 61 due to slippage with the surface. That is, when the rotating plate 31 comes into contact with a stopper member (not shown), the driven gear 61, the gear 44, the gear 45, and the rotating gear member 48 are stopped from rotating regardless of the rotation of the driving gear 62. The

  In addition, although said rotation operation demonstrated the case where the rotating plate 31 was rotated in the arrow G1 direction shown in FIG. 9, also in the case of the rotating operation which rotates the rotating plate 31 in the arrow G2 direction opposite to the arrow G1 direction. By performing the same rotating operation as described above, the rotating plate 31 is rotated in the arrow G2 direction, and the display body 10 (see FIG. 1) is rotated in the left direction (arrow B direction in FIG. 1).

  As described above, it is considered that the display main body 10 is normally rotated by pressing the auto turn button of the remote control. However, the display device of the present invention can rotate the display main body 10 even when the remote control is not found nearby. It has a configuration that can be done.

  As shown in FIG. 1, windows are respectively formed at the left and right ends of the front surface of the front cabinet 11, and a detection unit that detects a rotation operation instruction from a user is provided so as to face the windows. It is preferable to provide a translucent resin for the window. The detection unit can use, for example, an infrared sensor that detects a hand held up, and includes a right rotation detection unit 90 provided at the right front end of the front cabinet 11 and a left rotation detection provided at the front left end of the front cabinet 11. Part 91.

  The right rotation detection unit 90 and the left rotation detection unit 91 are connected to a control circuit unit (not shown) of the display body 10, and the right rotation detection unit 90 detects a rotation instruction in the right direction (arrow B direction). The left rotation detection unit 91 detects a rotation instruction in the left direction (arrow A direction). Then, like the input from the auto turn button of the remote controller, the stepping motor 42 of the display device turntable 20 is driven by the detection signal from the right rotation detection unit 90 or the left rotation detection unit 91.

  Therefore, when the user holds his / her hand in front of the right rotation detection unit 90, the right rotation detection unit 90 detects it and the stepping motor 42 is driven, and the display main body 10 rotates in the right direction. On the other hand, when the user holds his / her hand in front of the left rotation detection unit 91, the left rotation detection unit 91 detects it and the stepping motor 42 is driven to rotate the display main body 10 in the left direction. Since the rotation operation is continued only while the hand is held up, that is, while the detection unit is detecting, the rotation stops when the hand is removed.

  As a result, there is a problem in that the rotation is heavy due to deterioration over time, the rotation is difficult for people with weak power, and the remote control in the configuration that is rotated by the operation of the remote control. If it is not found, the problem that it cannot be rotated is solved, and it can be easily rotated.

  The positions of the right rotation detection unit 90 and the left rotation detection unit 91 are not particularly limited as long as they are easy to operate. However, it is preferable that the right rotation detection unit 90 is provided in the right half region of the liquid crystal display device 100 and the left rotation detection unit 91 is provided in the left half region of the liquid crystal display device 100 because it can be operated intuitively. For example, a window may be formed on the left and right ends of the upper surface of the cover member 21, and the right rotation detection unit 90 and the left rotation detection unit 91 may be provided so as to face the windows. It is preferable to provide a translucent resin for the window. In this case, if the right rotation detection unit 90 and the left rotation detection unit 91 are connected to the control unit of the display device turntable 20, the rotation operation can be performed without using the display main body 10, so various displays are attached. Is possible.

  Further, the right rotation detection unit 90 and the left rotation detection unit 91 may be provided on both the display main body 10 and the cover member 21, respectively. By doing so, the user can use it according to his / her preference, so the usability is improved.

  Further, the detection means of the detection unit is not particularly limited. In addition to the above infrared sensor, a light touch switch or the like that returns only when it is detected and released while being pressed may be used. For example, when the light touch switch is provided at the positions of the right rotation detection unit 90 and the left rotation detection unit 91 in FIG. 1, the user presses the light touch switch with an image of pressing and rotating the display body 10. Can be operated manually.

  In the above-described embodiment, an example in which a display device rotating table is provided in a liquid crystal display device as an example of a display device has been described. However, the present invention is not limited thereto, and a display unit (display panel) other than a liquid crystal panel such as an organic EL panel The present invention can also be applied to a configuration in which a display device rotation base is provided in a display device having a display.
