BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer input / output device, and more particularly to a computer input / output device which does not require an extra installation space and is excellent in operability.

[0002]

2. Description of the Related Art A handwriting input system has been developed in which a tablet with a display, which is composed of a digitizer for inputting with an electronic pen and a display for displaying output, which is integrated with the digitizer, is connected to a UNIX workstation. It was As shown in FIG. 13, in this system, the tablet 1 with a display is
It is a separate housing from the workstation 2, and both are connected to each other by a tablet signal cable 3 and a video signal cable 4. In this system, it is possible to connect the keyboard 5 in a separate casing to the workstation 2.

When a character is input by handwriting on the digitizer of the tablet 1 with an electronic pen, the input stroke coordinates are transferred to the workstation 2. The workstation 2 recognizes the input characters, and the recognition result is
It is displayed on the display of the tablet 1. On the other hand, when a character is input using the keyboard 5, the character corresponding to the key is displayed on the display of the tablet 1.

[0004]

However, the above-mentioned conventional handwriting input system has the following problems. When the handwriting input and the keyboard input are used together, the workstation 2, the tablet 1 and the keyboard 5 are installed side by side, which requires a large installation space. Since the tablet 1 and the keyboard 5 are separately connected to the workstation, a connection cable is required. When inputting by handwriting, the tablet 1 is installed almost horizontally, but when keyboard input is performed in this state, the display result is difficult to see because the keyboard 5 and the tablet 1 are horizontal to each other. When inputting by handwriting, the application program displays the dedicated handwritten character input frame to receive input, but when performing keyboard input by using this application program,
Before inputting from the keyboard, it is necessary to notify the application program by some operation that the keyboard will be input. In this case, the application program receives keyboard input without displaying the character input frame, as in the conventional case.

Therefore, an object of the present invention is to provide a computer for both handwriting character input and keyboard input which does not require an extra installation space and is excellent in operability.

As shown in FIGS. 5 and 6, the connecting means 9 may be a hinge type rotating mechanism capable of rotatably connecting the rear portion of the keyboard 6 and the front portion of the tablet 7.
Also in this case, as shown in FIG. 5, when inputting with the keyboard 6, the tablet 7 can be leaned against the keyboard 6, while when inputting with the digitizer, as shown in FIG. Can be overlaid. In order to protect the keyboard 6 when the tablet 7 is placed on the keyboard 6, it is preferable to form a ridge 7A on the back surface of the tablet 7.

FIG. 7 shows a block diagram of the computer main body 10. In FIG. 7, reference numeral 12 is a CPU. CPU12
Is the control center of the computer of the present invention, and ROM13
It also has the function of controlling each device according to the program stored in RAM14. An input / output control unit 15 has a function of controlling digitizer input and display of the tablet 7. 16
Is a switch signal detection unit that detects the up and down of the tablet 7 by an on / off signal from a switch described later. The CPU 12, ROM 13, RAM 14, input / output control unit 15 and switch signal detection unit 16 are commonly connected by a system bus 18.

As shown in FIG. 8, the switch 17 is turned on / off by the protrusion 17A on the lower surface of the link 11A of the connecting means 9. That is, at the time of keyboard input, the tablet 7
When the tablet 17 is leaned against the keyboard 6, the switch 17 is turned on by the protrusion 17A, while when the tablet 7 is placed on the keyboard 6 during digitizer input, the protrusion 17A separates from the switch 17 and the switch 17 is turned off. switch
The optical element 17 may be optical as well as mechanical.

Next, one embodiment of the computer of the second invention will be described with reference to the drawings.

FIG. 9 is a side view showing an embodiment of a computer of the second invention at the time of keyboard input, and FIG. 10 is a second view.
FIG. 11 is a side view at the time of input by a digitizer, showing one embodiment of the computer of the invention, and FIG. 11 is a side view at the time of keyboard input, showing another embodiment of the computer of the second invention.
12 shows another embodiment of the computer of the second invention,
It is a side view at the time of input by a digitizer.

As shown in FIGS. 9 to 12, the computer of the second invention comprises a keyboard 19, a tablet 21 in which a display 20 and a digitizer are integrally stacked, and a casing 22 capable of accommodating the tablet 21. The computer main body 23 fixed vertically in the casing 22, and the casing.
The keyboard 22 and the tablet 21 are connected to the keyboard 22 by means of a connecting means 24 for connecting them up and down.

A handle 25 is attached to the upper portion of the casing 22. Ventilation holes 22A, 22B for allowing the cooling air for the computer main body 23 to pass through are formed in the upper and lower portions of the rear surface of the casing 22. As a result, the computer main body 23 is naturally cooled so that the forced cooling fan is unnecessary and the problem of noise due to the cooling fan is eliminated.

The connecting means 24 is a link 26A connecting the lower part of the casing 22 and both side surfaces of the keyboard 19, and a link connecting the lower part of the casing 22 and both side surfaces of the tablet 21.
It consists of 26B. Since the link 26A is obliquely fixed to the position shown in FIG. 9, it becomes easy to input by the keyboard 19.

The tablet 21 is provided on the front surface of the casing 22.
Is formed with a recess 22C capable of accommodating therein.

Since the computer of the second invention is configured as described above, when inputting with the keyboard 19,
As shown in FIG. 9, the keyboard 19 is tilted almost horizontally in front of the casing 22 by the link 26A, and the tablet 21
Are vertically accommodated in the recess 22C of the casing 22 by the link 26B. In this case, the keyboard 19 is fixed obliquely, so that it is easy to input. On the other hand, when inputting with the digitizer, the tablet 21 is
Stack it on the keyboard 19 that lies horizontally in front of 22. In this case, since the rear end portion of the tablet 21 comes into contact with the step portion 22D formed in front of the casing 22, the tablet 21 is
It overlaps the keyboard 19 at a slight angle, and it becomes easy to input by the digitizer. If the tablet 21 is housed in the casing 22 and the keyboard 19 is rotated vertically, the keyboard 19
Has a function of covering the casing 22. In this way, the keyboard 19 and the tablet 21 are compactly stored in the casing 22.

The connecting means 24 may be constituted by a link 26B as shown in FIGS. 11 and 12. In this case, at the time of keyboard input, the keyboard 19 becomes completely horizontal, but the tablet 21 slightly overlaps the keyboard 19 as in the case of FIGS. 9 and 10.

In the second invention, as in the above-described first invention, the second invention also has a detection unit for detecting the arrangement of the keyboard 19 and the tablet 21 and sending the detection signal to the computer main body 23. By keyboard 19
And the tablet 21 can be selectively used.

[0026]

As described above, according to the present invention, the tablet is connected to the keyboard by the connecting means so that the tablet can be tilted up and down, and the computer main body is provided inside the housing of the tablet or the keyboard. No space is required and excellent operability can be obtained. In particular, according to the second aspect of the invention, a useful effect is obtained in which the computer main body in the casing is naturally cooled.
