Abstract

PROBLEM TO BE SOLVED: To obtain a plate type display unit which enables a transparent coordinate recognition device to be used freely on a keyboard or the plate type display unit by connecting the coordinate recognition device between the keyboard and plate type display unit rotatably on a hinge shaft. SOLUTION: The transparent electrostatic capacity type coordinate recognition device 31 is connected between the keyboard 35 and plate type display unit 32 rotatably on the hinge shaft 36. Projections 37 for a pad laid on the keyboard are formed at the periphery of the keyboard 35 and when the coordinate recognition device 31 is placed on the keyboard 35 for use, the coordinate recognition device 31 is prevented from pressing keys of the keyboard 35. Further, a drawing is placed between the coordinate recognition device 31 and keyboard 35 and a drawing can easily be traced on the coordinate recognition device 31 with a pen. When the coordinate recognition device 31 is placed on the plate type display unit 32 and used, the angle of rotation of the coordinate recognition device 31 is limited by the hinge shaft 36.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat panel computer, and more particularly to a flat panel computer having a coordinate recognizing device which can be used on a keyboard or a flat panel display device.

[0002]

2. Description of the Related Art A coordinate recognition device is a device that digitally detects the position coordinates of each point on a flat board or a figure or line segment and outputs the coordinates to XY coordinates. It is used for plotter and input of graphic information displayed in graphic form.

The flat-plate computer is a computer such as a notebook PC, a PDA (Personal Digital Assistant), and a pen PC which is used in a form in which a flat-panel display device and a keyboard are bent.

Since the input device of the PDA and the pen PC is the coordinate recognition device itself, there is a limit in inputting various information amounts. Therefore, it is necessary to equip a PDA and a pen PC with another keyboard, but at the present time, the demand is not sufficiently satisfied.

FIG. 2 is a schematic diagram for explaining a conventional pen PC with a built-in keyboard. A pen PC as shown in FIG. 2 is a US patent "ROTATABLE PEN-BASED COMPUTER (number 5, 43
2, 720) ". In this pen PC, a flat panel display device panel 12 is exposed on the front surface of a rectangular parallelepiped housing 10, and all parts including a keyboard are built in the housing. To take it out and use it, open the lid on the back of the housing 10,
The latch may be released manually. This pen pc
Can be used opposite or turned to the side. In this case, the user can operate the switch card 11 provided at the upper left end of the front surface of the housing 10 to adjust the screen direction.

FIG. 3 shows a conventional touch panel notebook.
It is a schematic diagram for explaining a PC. A notebook PC like the one shown in Fig. 3 is a US patent "COMPUTER AND DISPLAY APPARATU".
S WITH INPUT FUNCTION (number 5, 489, 92
4) ”. In this notebook PC, a flat panel display device 22 and a keyboard 21 are rotatably connected by a latch means 23. Therefore, during use, the flat panel display device 22 is externally mounted on the flat panel display device 22. When the physical pressure is applied, the whole notebook PC should not be shaken or overturned, and the projections 24 are formed on both side edges of the keyboard 21 so that the flat panel display device 22 and the keyboard are folded. 21 do not touch each other.

The above is the configuration of the conventional flat type computer, but in the case of the pen PC as shown in FIG. 2, it is not structurally suitable to use another coordinate recognition device in combination, and a keyboard is used. It is troublesome to take out and use. On the other hand, in the case of the notebook PC as shown in FIG. 3, another coordinate recognition device can be placed on the flat panel display device 22 and used. However, there is a problem in that the coordinate recognition device cannot be freely used on the keyboard 21 or the flat panel display device 22 according to the necessity of use.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to provide a coordinate recognizing device as a keyboard or a flat panel display device according to the necessity of use. It is to provide a flat-plate computer that can be used freely above.

[0009]

To achieve the above object, a flat-panel computer according to the present invention is a flat-panel computer having a keyboard and a flat-panel display, wherein the flat-panel display is one side of the keyboard. A transparent coordinate recognizing device rotatably connected to the keyboard by a hinge shaft provided in the keyboard and rotatably connected to the keyboard by the hinge shaft. It is characterized by that.

Therefore, the coordinate recognition device can be freely used on the keyboard or the flat panel display device according to the needs of use.

[0011]

Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 is a schematic view for explaining a flat panel computer to which the present invention is applied. As shown in FIG. 1, in the flat panel computer according to the present invention, a transparent capacitive coordinate recognizing device 31 is rotatably connected about a hinge shaft 36 between a keyboard 35 and a flat panel display device 32. ing. An underlay projection 37 is formed around the keyboard 35, and when the coordinate recognition device 31 is placed on the keyboard 35 for use, the coordinate recognition device 3 is used.
1 prevents the key of the keyboard 35 from being pressed. Further, a drawing can be placed between the coordinate recognition device 31 and the keyboard 35, and the drawing can be easily drawn on the coordinate recognition device 31 using a pen. When the coordinate recognition device 31 is used by placing it on the flat panel display device 32, the coordinate recognition device 3 is used.
The rotation angle of 1 is limited by the hinge shaft 36, and the pressure generated when the pen or finger is brought into contact with the coordinate recognition device 31 is applied to the flat panel display device 32 and the hinge shaft 36 separately. Therefore, it is possible to prevent the entire flat-plate computer from shaking or being overturned.

The configuration of the flat-plate computer according to this embodiment has been described above. Next, a method of using the computer will be described. When the user inputs a large amount of information using the keyboard 35, the input information of the coordinate recognition device 31 and the information displayed on the flat panel display device 32 are matched 1: 1 or the touch screen type. When the display device is used, the coordinate recognition device 31 may be placed on the flat panel display device 32 and used.

On the other hand, when inputting a precise pattern for the character recognition function or the like, the coordinate recognition device 31 may be placed on the keyboard 35 for use.

The present invention is not limited to the above-described embodiment, and can be used and improved. For example, if a pressure sensor is attached on the underlay protrusion 37, the pressure applied to the keyboard 35 can be monitored through the coordinate recognition device 31. Further, when the micro switch is attached on the underlay protrusion 37, the current position of the coordinate recognition device 31 can be monitored.

[0016]

As described above, the flat-plate computer according to the present invention has an advantage that the coordinate recognition device can be freely used on the keyboard or the flat-panel display device if necessary in use.
