DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable personal computer.

[0002]

2. Description of the Related Art As a portable personal computer, a portable personal computer having a liquid crystal panel in a display device has been put to practical use. In such a portable personal computer, as the area of the liquid crystal panel increases, the production yield decreases, so that it is difficult to realize a large screen at low cost. There is a problem that the portability of a personal computer is impaired. Therefore, in order to solve this problem, a portable personal computer having an external output terminal capable of outputting an image display signal not to a display device but to an external CRT display device is employed.

[0003] Such a conventional portable personal computer will be described with reference to the drawings.

In FIG. 8, a portable personal computer 1 includes a main body 3 having a keyboard 2 on an upper surface and a storage device, a central processing unit and the like inside, a display device 5 having a liquid crystal panel 4, and The main body 3 and the display device 5 are
The display device 5 comprises a hinge 6 which is rotatably connected to the main body 3 within a range of 0 to 180 °.

In FIG. 8, the portable personal computer 1 is provided with an external output terminal (not shown) on the back of the main body 3. It is connected to a large external CRT display 8.

The above-mentioned portable personal computer 1
Can output the image display signal to the external CRT display device 8 having a larger screen than the liquid crystal panel 4, so that the operator can operate the portable personal computer 1 comfortably.

Further, in the portable personal computer 1, the display device 5 is rotated around the hinge 6 toward the main body 3 so that the main body 3 and the display device 5 are closed and folded to be carried. Since it can be in a convenient form, it can be easily carried.

[0008]

However, in the conventional portable personal computer 1, it is necessary to operate the keyboard 2 on the upper surface of the main body even when the portable personal computer 1 is connected to the external CRT display device 8 and used. In addition, the display device 5 must be opened to almost 90 degrees with respect to the main body 3, and this display device 5 blocks an operator's view when viewing the external CRT display device 8, so that operability deteriorates. There was a problem that.

If the display device 5 is opened to almost 180 degrees with respect to the main body 3, the display device 5 does not obstruct the field of view of the operator when viewing the external CRT display device 8, so that the operability deteriorates. However, since the hinge 6 that connects the main body 3 and the display device 5 operates only rotatably, there is a problem that the installation area of the portable personal computer 1 increases. Was.

Further, even if an external CRT display device 8 is connected to the conventional portable personal computer 1 and an image display signal is output to the external CRT display device 8, power is continuously supplied to the display device 5. Therefore, there is a problem that wasteful power is consumed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has improved operability without obstructing a field of view of an operator when viewing an external CRT display device.
