2. Description of the Related Art Currently, a display apparatus
LCD's focus product is. Such an LCD is characterized by a thin flat plate shape, and since it is thin, it is a CRT (Cathode) for a conventional desktop computer.
Ray charge-storage tube) It occupies only about 1/10 of the area occupied by the monitor. Therefore, while the working space of the desk is expanded and the work efficiency is improved, the resolution of the screen is inferior due to the light incident from the side of the convex surface of the cathode ray tube used in the conventional CRT monitor, but the LCD monitor is a flat plate. Therefore, even if light is incident from the side surface, it has a vivid resolution.

FIG. 1 is an exploded perspective view showing a conventional angle adjusting device for an LCD monitor.

In general, the LCD monitor (1) includes a front case (2), a rear case (3) which is joined to the front case (2) to form the appearance of the monitor (1), and a front case (2). ) Fixedly supported on the rear case (3) and mounted on the rear case (3) by a main printed circuit board (not shown in the drawing), an LCD panel (not shown in the drawing) that displays characters or symbols by an electric signal approved by And a stand (5) pivotally fixed to the rear surface of the rear case (3) so as to tilt the monitor (1) in the vertical direction.

At this time, the lower end of the frame (6) connecting the monitor (1) and the stand (5) is integrated with the stand (5) so that the LCD monitor (1) is tilted toward the user. Shape (or the lower end of the frame (6) is rotatably hinged to the stand (5)), and the upper end of the frame (6) is integrally formed on the back surface of the rear case (3). A fixed shaft (7) fastened to the fixed yoke (4) and a plurality of washers (8) made of metal, which are disposed on the left and right sides of the yoke (4) and are in close contact with each other.
The hinges are rotatably fixed by the mutual contracting forces of. (Or fixed to the back of the rear case (3) in one piece).

However, the tilt torque of the frame (6) fixed to the back of the rear case (3) so as to tilt the LCD monitor (1) is adjusted to the above-mentioned fixed shaft (7) and the metal material. By arbitrating by the mutual contracting force with the washer (8), the user can
The monitor (1) is not easily and freely tilted.

That is, in the hinge structure of the LCD monitor (1) described above, when the tilt torque values of the fixed shaft (7) and the washer (8) are set too high, the user can monitor in an optimum posture. Moreover, it becomes difficult to operate the LCD monitor (1) so as to tilt it at a predetermined angle.

On the contrary, when the tilt torque value of the fixed shaft (7) and the washer (8) is set too low, the LCD monitor (1) may be damaged by external shock or contact. There is a problem that it is easy to chill, contrary to the intention of the user.

As mentioned above, in the hinge structure,
With the increase in the number of parts that form the hinge, cost cost rises, and the problem of losing price competitiveness from the same industry field,
There are more overall work steps to assemble these parts,
There is a problem that the workability is extremely poor.
