DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be specifically described with reference to the drawings for each of its preferred embodiments.

FIG. 1 is a perspective view showing a first embodiment according to the present invention.

In FIG. 1, the LCD panel 2 is constructed so that it can be rotated around the center of the lower side surface of the LCD panel 2 having the display unit 1 as a fulcrum 3. The LCD panel 2 and the computer main body 5 are connected by a rotary shaft 4 provided at the fulcrum 3 so that only the LCD panel 2 can be rotated in the left-right direction, that is, in the clockwise or counterclockwise direction. The rotating shaft 4, a columnar 22 described below connected to the lower end of the rotating shaft 4, and a portion including these peripheral parts constitute a rotating means which is one of the features of the present invention.

The LCD panel 2 as the main body 5 is rotated in the left-right direction (clockwise or counterclockwise) by the rotary shaft 4, and the wiring 21 between the LCD panel 2 and the main body 5 is passed inside the rotary shaft 4. Therefore, as described in detail later, LC
The D panel 2 does not rotate all around.

A groove 6 for accommodating the rotary shaft 4 is provided on the main body 5 side so that the rotary shaft 4 can be fitted into the main body 5 when the LCD panel 2 is closed, that is, when the computer is not used. Has been formed.

FIG. 2 shows the main body 5 of the rotary shaft 4 in this embodiment.
It is sectional drawing of the connection part 7 of the side.

In FIG. 2, the portion of the rotary shaft 4 inserted into the main body 5 is a cylinder 22, and the lower end of the rotary shaft 4 is connected to the cylinder 22 via a hinge 9. On the computer body 5 side, a recess is formed along the cylinder 22 for supporting the cylinder 22 of the rotating shaft 4.

In the center of the cylinder 22, the LCD is viewed from the main body 5 side.
A hole 24 is formed for passing the wiring 21 reaching the panel 2 side. Further, since the wiring 21 is also passed through the hole formed in the rotary shaft 4, the wiring 21 is not rotated at an excessive rotation angle Θ.
To protect it from the outer peripheral side of the cylinder 22 and the recess 2 of the main body 5.
Small protrusions 25a and 25b are formed on the inner side of 3, and these protrusions serve as rotation stoppers 25. The stopper 25 prevents the LCD panel 2 from rotating around the entire circumference by the rotation of the rotary shaft 4.

A protrusion 25a which is a component of the stopper 25
The projection 25b is mounted on the inner surface of the recess 25 of the main body 5 at a position of approximately 90 ° in the left-right direction toward the normal position, below the surface of the LCD panel 2 that is in the normal position on the side surface of the cylinder 22. The projections 25a and 25b are both small rectangles along the vertical direction of the cylinder 22, and have a permissible range of the rotation angle Θ (270 ° to the right from the normal position, 90 to the left).
When these two rectangular parallelepipeds or projections 2 are exceeded,
5a and 25b are overlapped and engaged with each other to prevent the rotation angle Θ from being further increased.

With the above mechanism, the LCD panel 2 can be rotated clockwise or counterclockwise by the rotary shaft 4. Here, in order to prevent the LCD 2 from easily rotating by a slight pressure applied to the LCD 2, the frictional force of the rotational engagement between the column 22 and the recess 23 of the computer main body on which the column 22 is rotatably supported is slightly increased. Need to be kept. For example, engagement by an elastic body or concavo-convex coupling in which a concave portion and a convex portion (sphere) are coupled to rotate and lock at a constant angle is an effective means.

FIG. 3 is a schematic diagram for explaining the rotating direction of the rotary shaft 4 in the present embodiment, and the rotary shaft 4 is seen from above.

Referring to FIGS. 3 (a)-(d), FIG.
(A) to (d) show that the LCD panel 2 is moved counterclockwise by about 270 ° from the normal position. Figure 3 (a)
Since the LCD panel 2 is in the normal position, the projection 25a on the side of the cylinder 22 is located in the front, and the projection 25b on the side of the main body 5 is located at 90 ° to the left from the normal position. From this state, when the LCD panel 2 is moved rightward (counterclockwise) toward the normal position, that is, in the direction of the arrow in the figure, the LCD
The panel 2 is displaced as shown in FIG. 3 (a) → (b) → (c) → (d), and when it is rotated 270 ° toward the normal position in FIG. 3 (d), the protrusion 25a on the cylinder 22 side is the main body. The LCD panel 2 cannot rotate any more because it is engaged with the protrusion 25b on the fifth side.

Similarly, FIG. 4 illustrates moving the LCD panel 2 90 ° to the left from the normal position.

Referring to FIGS. 4A and 4B, FIG.
In (a), since the LCD panel 2 is in the normal position, the column 22
Also, the protrusions 25a and 25b on the main body 5 side are located at the same positions as in FIG. From this state, when the LCD panel 2 is moved leftward (clockwise) toward the normal position, that is, in the direction of the arrow, when the LCD panel 2 is rotated 90 ° toward the normal position in FIG. 25a and 25b
Abut (engage) with each other, and the LCD panel 2 does not rotate any more.

By the rotating means described above, the wiring 21 between the LCD panel 2 and the main body 5 has a rotation angle Θ more than necessary.
Can be protected from.

FIG. 5 is a diagram showing a schematic structure of a tilting means which is another feature of the present invention, and is a view showing a tilt angle Θ'of the LCD panel 2 in this embodiment.

Referring to FIG. 5, the tilting means includes a shaft 8 which is arranged at a connecting portion between the LCD panel 2 and the rotary shaft 4 and which is substantially orthogonal to the rotary shaft 4. Since the rotary shaft 4 moves only in the left and right directions (clockwise and counterclockwise), the LCD
The tilt angle Θ'of the LCD panel 2 can be changed in several steps by the axis 8 of the connecting portion between the panel 2 and the rotary shaft 4, and thus the LCD panel 2 is adjusted to the angle Θ'which is the most observable during operation. It becomes possible. LCD by axis 8
The change in the front-back direction of the panel 2 is possible continuously,
It can also be performed intermittently at a certain fixed angle. Also L
In order to prevent the CD panel 2 from moving in the front-rear direction with a slight pressing force, the shaft 8 needs to have a large frictional force. The rotation angle Θ and the tilt angle Θ'are independent of each other.

FIG. 6 is a perspective view of the lower portion of the rotary shaft 4 in this embodiment.

In FIG. 6, a mechanism for opening and closing the LCD panel 2 is shown here. The rotating shaft 4 and the cylinder 22 are connected by a hinge 9, and the hinge 9 on the cylinder 22 side is fixed. Therefore, the opening / closing operation of the LCD panel 2 is performed by the hinge 9.

FIG. 7 is a perspective view showing a second embodiment according to the present invention.

Referring to FIG. 7, in the second embodiment of the present invention, the LCD panel 2'and the rotating shaft 4'are integrally formed on the same plane, and the tilt angle Θ'of the LCD panel 2'is formed. No change can be made at the connecting portion 8 between the LCD panel 2'and the rotary shaft 4 '. In the second embodiment shown here, the inclination angle Θ'of the LCD panel 2'is changed in a stepwise manner by utilizing the rotation shaft 4'and the hinge 9'of the cylinder 22 '. ing.

It is needless to say that the same effect as that of the first embodiment can be obtained by the second embodiment described above.
