Has been interposed. Generally, a floppy disk drive is used as the external recording device. A control board 10 for controlling the entire apparatus is disposed below the main body lower case 9.

On the other hand, a hinge mechanism 11 and a hinge fitting 12 rotatably support the space between the lid 3 on which the liquid crystal processing device 2 is disposed and the upper case 8 of the main body. The hinge mechanism 11 is disposed at an end in the depth direction of the main body, and rotatably supports between the lid 3 in which the liquid crystal processing device 2 is disposed and the upper case 8 of the main body.
Further, it has a predetermined holding torque for stopping the lid at an arbitrary position. FIG. 3 shows details of the hinge mechanism.

Here, the cable 13 connecting the cover 3 containing the liquid crystal display device 2 according to the present invention and the control board 10 of the main body will be described.

FIG. 4 is an exploded view of a connection cable for connecting the lid containing the liquid crystal display device to the control board of the main body, and FIG. 5 is a forming view thereof. In the figure, a terminal A is connected to a power supply board 5 of the liquid crystal display device 2 and a terminal B is connected to a fluorescent tube 14.
The terminal C is connected to the control board 10 of the main body, and the whole is constituted by one flexible printed circuit (FPC cable). The FPC cable 13 includes a cable 131 for the power supply board 5 of the liquid crystal display device 2, a cable 132 branched from the cable 131 for the inverter board 6 of the fluorescent tube 14, and a cable 133 for the control board 10 of the main body.
And the root 19 of the cable 131 and the cable 13
3 and a connecting portion 17 electrically and mechanically connected between these root portions 18 and 19, and the terminals A, B and C provided at the end of the cable. ing.

In order to form a preformed FPC cable as shown in FIG. 4 as shown in FIG. 5, first, a cable 132 for the inverter substrate 6 of the fluorescent tube 14 is bent at a right angle to the right in FIG. The portion C of the cable 133 is bent once in the opposite direction (vertical direction in the figure), and further bent at a right angle in the upper left direction in the figure to form a shape as shown in FIG.
The end of the portion C is electrically connected to each substrate of the information device as shown in FIG. Although the electrical connection in the present invention is not described in detail, it is a connector connection.

At this time, the cable 133 is on the main body side, and the cables 131 and 132 are on the liquid crystal display side. Since the main body and the liquid crystal display side are freely opened and closed by a hinge mechanism, bending or bending stress is constantly applied to the cable, and how to arrange the cable in the hinge portion is a major issue.

The present invention has the following structure to enhance flexibility and prevent disconnection or breakage of the cable caused by opening and closing of the lid.

That is, first, an outlet 16 is formed at the root of the lid 3 so that it can be easily pulled out from the flange portion 15 of the case, which is the rotation support portion of the lid 3 containing the liquid crystal display device 2. The connection portion 17 of the cable is rounded and rounded according to the size of the outlet 16 to form a cylindrical portion, and a tape is wound around the outer periphery thereof to hold and fix the cylindrical shape and dimensions. Insert and fix. On the other hand, the root portions 18 and 19 of the cable are formed so as to be respectively rounded in a spring shape and pulled out in a predetermined direction.

In this state, when the lid 3 accommodating the liquid crystal display device 2 is opened and closed, the cable rotates along the flange 15 of the case, which is a rotation supporting portion of the lid 3.

At this time, the connecting portion 17 is connected to the flange 1 of the lid 3.
5, the roots 18, 19 of the cable 13 are rounded once or more than once, as shown in FIG. 3, in the vicinity of the draw-out portion of the flange 15 of the case. Therefore, it can flexibly follow the opening and closing of the lid, and the cable is not damaged. Even if the cable 13, especially the roots 18, 19, are in contact with the mating parts, they rotate only on the inner side, so that the cable does not wear due to rubbing, and the life is greatly extended.

Although the flange 15 is provided on the lid 3 in the above embodiment, the same applies to the case where the flange 15 is provided on the main body. In addition, the fact that the connecting portion 17 is sandwiched between the flange portions 15 is effective in preventing the cable from being accidentally moved, and in some cases, the cable may be loose. Further, the cable may be a flexible cable having so-called wiring.
