In addition, the upper surface of the pedestal 20 is formed with an annular groove 24 is fixed to the annular roller pedestal 15, the plurality of rollers 16 are rotated at a constant angle to the annular roller pedestal 15 The freely arranged is arranged, the upper side of the roller 16 is in contact with the slide portion 14 of the rotary plate 10 to facilitate the rotation of the rotary plate 10. On the bottom of the pedestal 20, a reduction motor 25 which is operated by remote control of the remote controller 3 is fixed, and a small diameter gear 26 is fixed to the motor shaft 25a of the reduction motor 25. The small diameter gear 26 is located on the upper surface of the pedestal 20 to be engaged with the large diameter gear 13 of the rotating plate 10. On the other hand, the locking device 30, as shown in Figs. 2 to 7, is provided on one side of the swivel device as described above. The locking device 30 indirectly locks the locker 31 and the locker 31 to intentionally prevent rotation of the rotating plate 10 by selectively pressing the large diameter gear 13 of the rotating plate 10. A lever 36 for actuation and a rod 37 connected between the locker 31 and the lever 36 to transmit the operation of the lever 36 to the docker 31. The locker 31 is rotatably fixed to the shaft 32 on the pedestal 20 corresponding to the large-diameter gear 13 of the rotary plate 10, the first and second on the edge on the circular plate 33 The rotary parts 34 and 35 are protruded so as to substantially face each other. The large diameter gear 13 of the rotating plate 10 is positioned between the first and second all-pieces 34 and 35, and the first and second diameters allow the large diameter gear 13 to rotate freely. The linear spacing between the rotating parts 34 and 35 is sufficiently maintained. The first rotating part 34 of the locker 31 is provided with a gear part 34a on a surface facing the large diameter gear 13, and this gear part 34a is a table for rotating the locker 31. Meshes with the gear 13. In addition, the second rotating part 35 of the locker 31 has the same circular arc surface as the inner surface of the large diameter gear 13 so as to press the inner surface 13a of the large diameter gear 13 when the locker 31 rotates. It has the pressing surface 35a which has. The lever 36, which indirectly operates the locker 31, has a disc 36a rotatably fixed to the bottom of the pedestal 20, and protrudes from one side of the disc 36a, so that one side of the pedestal 20 is provided. The handle 36a is exposed. Between the locker 31 and the lever 36 is a rod 37 for transmitting the operation of the lever 36 to the locker 31 is connected, one end of the hoisting rod 37 is the disc of the lever 36 The pin 38 is movably connected to a predetermined position on the 36a so that the rotational movement of the knob 36 is converted into the linear movement of the rod 37, and a rack 37a is provided below the rod 37. The rack 37a is engaged with the pinion 39 fixed to the rocker 31 and the same shaft 32 to convert the linear motion of the rod 37 into the rotational motion of the rocker 31. In addition, one side of the rod 37 is supported by the guide portion 18 fixed to the bottom surface of the pedestal 10 with a screw 17 so that the linear motion of the rod 37 is constant.

As described above with reference to FIGS. 1 to 3, when the viewer operates the remote controller 3 to rotate the screen of the TV receiver 1 at a desired angle, the remote controller receiver of the TV receiver 1 is provided. The sensor detects this and sends a signal to the motor driver (not shown) in the TV receiver 1, and the motor driver receives the signal to drive the reduction motor 25.

Therefore, when the reduction motor 25 is rotated, the small diameter gear 26 fixed to the motor shaft 25a of the reduction motor 25 is rotated so that the rotation plate 10 engaged with the small diameter gear 26 is engaged. Since the large-diameter gear 13 is rotated, the TV receiver having the rotary plate 10 fixed to the bottom surface thereof may be rotated in the rotation direction of the rotary plate 10, and the remote controller 3 controls the selection keys in the left and right directions. Since the motor driving unit determines the rotation direction of the reduction motor 25, the TV receiver 1 may be rotated to the left or the right according to the rotation direction of the reduction motor 25. In addition, the TV receiver 1 Is rotated around the support portion 11 of the rotating plate 10 and the assembly portion 22 of the assembled pedestal 20, and the rotating plate 10 is interposed between the pedestal 20 of the slide portion 14 The rotation of the TV receiver 1 is made smoother by the rollers 16. Also, the guide of the loop formation of the rotating plate 10 is guided. By allowing the protrusions 23 of the pedestal 20 to be guided to the 12, the protrusions 23 of the pedestal 20 move along the guide grooves 12 having a ring shape when the rotating plate 10 is rotated. Since the annular guide groove 12 is not continuously formed and is stopped in the middle, the projection 23 prevents the guide groove 12 from rotating at one end anymore, so that the TV receiver 1 rotates 360 °. The angle of left and right rotation of the TV receiver 1 can be determined according to the length of the guide groove 12 through which the protrusion 23 can be guided. The device needs to be fixed so that the TV receiver does not rotate, for example, when carrying the TV receiver 1 or to prevent children from playing around, as shown in Figs. The knob 36 of the lever 36 of the locking device 30 exposed in the In operation, the disc 36a of the lever 36 is rotated counterclockwise to pull the rod 37 in the direction of the arrow, and the rack 37a on one side of the rod 37 is the same as the locker 31. Since it is engaged with the pinion 39 fixed on the shaft 32, the circular plate 33 of the locker 31 is rotated in the clockwise direction. Since the first and second rotary parts 34 and 35 formed on the circular plate 33 are also rotated clockwise by the rotation of the circular plate 33, the first rotary part 34 may be rotated as shown in FIG. 5. While the gear part 34a meshes with the large diameter gear 13 of the rotating plate 10, the pressing surface 35a of the second rotating part 35 presses the inner surface 13a of the large diameter gear 13. It becomes open. Therefore, since the large diameter gear 13 is pressed and fixed by both sides by the first and second rotating parts 34 and 35 of the locker 31, the remote control 3 can be operated to drive the reduction motor 25. The receiver 1 is not rotated, and in particular, the TV receiver is prevented from being rotated due to the transport of the TV receiver or the mischief of children.

As described above, when the locking device 30 is to be released in the locked state, the lever 37 of the locking device 30 is operated again in the opposite direction to the arrow as the reverse operation of the locking operation, and the rod 37 is arrowed. It is operated in the opposite direction to rotate the locker 31 in the counterclockwise direction, so that the gear portion 34a of the first rotating portion 34 formed on the circular plate 33 is locked from the large diameter gear 13 of the rotating plate 10. Since the pressing surface 35a of the second rotating part 35 is spaced apart from the inner surface 13a of the large diameter gear 13, the large diameter gear 13 is again placed in a rotatable state.

As described above, according to the swivel device of the TV receiver according to the present invention, a locking device capable of preventing rotation of the TV receiver when necessary is connected to the swivel device, so that the TV receiver can be transported from the TV receiver or unreasonably mischievous. The malfunction of the swivel device can be prevented.
