Further, the power cable 16 is laid in parallel with the flat cable 10, and the flat cable 10 and the power cable 16 are fixed to the cable holder 9 by a cable retainer 17 so as not to float.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin display device, and more particularly to a thin display device in which a rotating portion and a fixed portion are connected by a flat type signal cable.

[0002]

2. Description of the Related Art Conventionally, in a thin display device, a liquid crystal display section and a support section for supporting the display section are integrally assembled, and the display section tilts (pivots vertically).
It was not possible to swivel (horizontal swing). When the display unit is not oriented toward the operator, the operator generally directs the entire display device toward himself before starting the work.

However, in recent years, since the size of the display unit has increased, the weight of the display device has increased, and even if the operator tries to change the direction of the entire display device, there is a situation in which it cannot be changed easily. Therefore, a structure in which the display unit can be tilted and also a swivel can be considered. In this case, the display section and the support section are connected by a flat cable, and the flat cable is housed in the support section.

[0004]

However, in the above-mentioned prior art, no consideration is given to the twisting and stretching of the flat cable, and when the display unit is tilted or swiveled, the flat cable is excessively twisted or stretched. The stress is added, and in the worst case, the flat cable is broken.

If the cable connecting the display (CRT) and the support is circular, as in Japanese Patent Laid-Open No. 1-163811, excessive stress is applied to the connecting cable due to twisting or expansion and contraction during tilt / swivel operation. Is not added, and there is no problem such as disconnection of the connection cable.

An object of the present invention is to reduce the stress applied to the flat cable by avoiding the flat cable from excessively twisting or expanding and contracting even when the display section is tilted or swiveled. A display device is provided.

[0007]

In order to achieve the above-mentioned object, the present invention provides a thin display section, a support section for supporting the display section, and a display provided between the display section and the support section. In a thin display device including a tilt / swivel mechanism unit that allows the unit to rotate in the left-right direction and the up-and-down direction, and a flat cable that connects the display unit and the support unit, the flat cable is provided along a central axis. Both end portions are rounded inward, and the rounded flat cable is stored in the support portion in a bent state.

Further, according to the present invention, a thin display section, a support section for supporting the display section, and a display section provided between the display section and the support section are rotatable in the horizontal and vertical directions. In a thin display device including a tilt / swivel mechanism unit and a flat cable connecting the display unit and a supporting unit, both end portions of the flat cable are rounded inward along a central axis, and the rounded flat The cable is accommodated in the supporting portion in a bent state, and a part of the accommodated flat cable is fixed to the supporting portion.

Further, the support base for a thin display device of the present invention is one in which both ends of the flat cable are rolled inward along the central axis, and the rolled flat cable is stored in a bent state. is there.

Further, in the support base for a thin display device of the present invention, the flat cable is rounded inward at both end portions along the central axis, and the rounded flat cable is stored and stored in a bent state. A part of the flat cable is fixed to the support body.

Further, the cable holder of the present invention has an accommodating portion for accommodating the flat cable in a U-shaped bent state, which is attached inside the supporting base for the thin display device.

[0012]

According to the above construction, by rolling the flat cable inward along the central axis, the twist applied to the flat cable is dispersed when the display section is swiveled, and the stress caused by the twist is reduced. You can

Further, since the flat cable is accommodated in the supporting portion in a bent state, it is not necessary to expand and contract the flat cable when the display section is tilted, and the stress due to expansion and contraction can be reduced.

Further, by fixing a part of the flat cable to the supporting portion, the flat cable is prevented from moving inside the supporting portion during the tilt / swivel operation.
Friction between the flat cable and the inner surface of the support portion can be prevented.

The interface circuit section 6 and the external input section 7 are connectable to the outside. And the device upper unit 1
And the device lower unit 5 are connected to each other via a tilt / swivel mechanism 8.

FIG. 2 shows the internal structure in detail by disassembling a part of the apparatus lower unit 5. A cable holder 9 is provided inside the device lower unit 5, and an interface circuit section 6 is provided below the cable holder 9. One end side of a flat cable 10 is connected to the interface circuit section 6, and the flat cable 10 is drawn into the cable holder 9 and then penetrates through a through hole 11A of the upper cover 11 of the lower unit 5 of the apparatus and the other end thereof. The side is connected to the upper device unit 1. Inside the upper device unit 1, the other end of the flat cable 10 is connected to the control unit 3.

FIG. 3 shows the structure of the tilt / swivel mechanism 8. As shown in the figure, a hinge portion 1 for connecting the apparatus upper unit 1 and the apparatus lower unit 5
2 is fixed to a support plate 13, and this support plate 13 is attached to the upper surface of the upper cover 11 of the device lower unit 5 so as to be rotatable around a rotation shaft 14. Then, the apparatus upper unit 1 can perform a tilt operation that rotates about the hinge portion 12 and a swivel operation that rotates about the rotation shaft 14.

FIG. 4 shows a plane of the cable holder 9 accommodating the flat cable 10, and FIG. 5 shows a cross section taken along the line AA of FIG. As shown in the figure,
In the cable holder 9, both ends of the flat cable 10 along the central axis are rounded inward to have a substantially circular cross section, and an insulating tape 15 is wound around the outside. The flat cable 10 wound with the insulating tape 15 is housed in the cable holder 9 in a U-shaped bent state. A power cable 16 is wired in parallel with the flat cable 10. The flat cable 10 and the power cable 16 are fixed to the cable holder 9 by a cable retainer 17 so as not to float. There should be some space between the cable retainer 17 and both cables 10 and 16, and both cables 10 and 1 can be moved by tilting and swiveling.
Even if the cable 6 is expanded or contracted or twisted, both cables 10 and 16 can move smoothly. The position where the flat cable 10 is fixed by the cable retainer 17 is not limited to one, but may be several.

FIG. 6 shows the cable holder 9 in detail. A partition wall 18 is formed inside the cable holder 9,
The flat cable 10 and the power cable 16 can be accommodated in a U-shaped bent state. In addition, a sufficient space is provided on both sides of the partition 18 so that the flat cable 10 and the power cable 16 can maintain a predetermined distance.

[0021]

As described above, according to the present invention,
Both ends of the flat cable along the central axis are rolled, and the rolled flat cable is stored in the fixed part in a bent state, so even if the flat cable is twisted or stretched during tilt / swivel operation, Twisting and expansion and contraction are absorbed and the stress on the flat cable is reduced,
It is possible to prevent breakage of the flat cable.

Further, since twisting and expansion and contraction of the flat cable are absorbed, even if a cable which is difficult to bend depending on the bending direction is used, a smooth tilt / swivel operation can be maintained.
