Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device having a keyboard for inputting data.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. 4-95114 will be described as a prior art. FIG. 12 is a tilted view of the book type personal computer with the lid body opened, and FIG. 13 is a tilted view of the book personal computer with the lid closed. When the cover is closed in this way, the size is as compact as a book or magazine, and it is excellent in portability.

The book-type personal computer shown in FIG. 12 has a main body 200, a lid 400, and a pair of hinges 6.
It consists of 00a and 600b. The main body 200 and the lid 400 are rotatably coupled by hinges 600a and 600b, and a battery chamber 1400 is provided between the hinges 600a and 600b. This battery chamber 1400 is arranged in two rows in which three cells are arranged in the longitudinal direction, which is different from the conventional arrangement in which two cells are arranged in the longitudinal direction in three rows. As a result of this, the depth of the battery compartment 1400 becomes smaller and the lid
The battery compartment 1400 does not become an obstacle when rotating the 400. A keyboard with an ASCII layout on the surface of the main body 200
1000, and a floppy disk drive device 1200 is provided inside the right side portion as in the conventional case (see FIG. 14). Lid part
A liquid crystal display unit 2200 is provided on the surface facing the keyboard 1000 when 400 is closed, and a slide type contrast adjustment volume 2400 and a brightness adjustment volume 2600 are provided in the vicinity of the right side. To the far right of these, an indicator 3200 indicates the current operating status of the device by means of LEDs.

FIG. 14 is a side cross-sectional view with the lid body closed as shown in FIG. Keyboard 10 as shown in this figure
00 is lower in the front than in the rear with respect to the bottom surface of the main body 200. That is, when the keyboard 1000 is used, the keyboard 1000 is inclined so as to be lowered from the rear to the front. First
Although FIG. 15 is exaggerated for easy understanding of the inclination, the inclination angle θ is about 1 to 2 degrees when the rear portion of the keyboard 1000 is considered as a fulcrum.

In the case where only a keyboard is sold on the market, it is easy to operate the keys so that the top surface of each key meets the inclination angle, assuming that the front part is lowered when it is assembled into the main body. Often has a shape. Therefore, if the tilt angle is set when the keyboard is attached, the usability of the keyboard commercially available alone can be maintained even in the book type personal computer. Further, although the inclination angle of 1 to 2 degrees seems to be small, the difference in ease of operation can be felt by actually touching the hand. On the other hand, with such an inclination angle, the influence on the thickness of the entire apparatus is extremely small, and the portability is not impaired.

Instead of fixing the keyboard 1000 as described above, the inclination angle of the keyboard 1000 can be changed by using the front portion as a fulcrum. This makes it possible to further reduce the overall thickness when the lid 400 is closed. In other words, when used, the rear part is lifted with the front part as a fulcrum, and when stored, the front part of the keyboard 1000 is used as a fulcrum and the rear part is rotated into the main body 200 to reduce the overall thickness and improve portability. Can be made.
