Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen input type external character creating device for a personal computer or a word processor having an external character registering function, and more particularly to a pen input type external character creating device with improved operability.

[0002]

2. Description of the Related Art Conventionally, an external character creating device used in a personal computer or a word processor has generally been a combination of a keyboard as an input device and a CRT as a display output device.

A pen input type external character creating apparatus for creating an external character by touching a matrix-shaped touch panel with a pen is an example of an apparatus that enables more efficient input than the keyboard input method. Sho 5
No. 8-165130. FIG. 4 shows an external view of this device. In this device, the “display” key 303 or the “erase” key 304 is selected before the touch panel 301 is touched with the pen 300.
Select the "Display" key 303 and press it to select the pen 300
Touch the touch panel 301 with to display the touch position. Select the "erase" key 304 and press it to touch the pen 3
When the touch panel 301 is touched with 00, the display of the touch position is erased.

[0004]

As described above, in the conventional pen input type external character creating apparatus, it is necessary to provide a key for instructing whether to display the portion touched by the pen or to erase the display. Therefore, during the creation of the external character, it is necessary to operate the keys in addition to touching the touch panel with the pen, and there is a drawback that the operability is poor.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a pen input type external character creating apparatus having improved operability by enabling an external character to be created by simply touching a touch panel with a pen. is there.

[0006]

A pen-input type external character creating apparatus according to the present invention is made to achieve the above object, and detects an input pen and a contact position on the upper surface by the input pen. Together with a translucent touch panel, a display unit that is provided on the lower surface of the touch panel and displays the contact position from the lower surface of the contact position of the touch panel, and the display unit based on the contact position detected by the touch panel. And a control unit for controlling.

The control unit displays the contact position on the display unit when the contact position detected on the touch panel is not yet displayed on the display unit, and the contact position detected on the touch panel. If is already displayed on the display unit, the display of the contact position is erased on the display unit.

A liquid crystal display may be used for the display section.

[0009]

When the touch panel is touched by the input pen, the touched position is detected by the touch panel and input to the control unit. The control unit determines whether the contact position is already displayed on the display unit. When the contact position is not displayed, the control unit causes the display unit to display the contact position. When the contact position is already displayed, the control unit causes the display unit to erase the display of the contact position. The contact position is displayed at the position from the display unit below the touch panel.

Further, the liquid crystal display is high definition and thin.

[0011]

FIG. 1 is a block diagram showing an embodiment of a pen input type external character creating apparatus according to the present invention. Hereinafter, description will be given with reference to the drawings.

The pen-input type external character creating apparatus is provided with an input pen 1.
And a touch panel 2 which detects a contact position on the upper surface by the input pen 1 and has translucency, and a display unit which is provided on the lower surface of the touch panel 2 and displays the contact position from the lower surface of the contact position of the touch panel 2. And a control section 11 including a CPU 4, a ROM 5 and a RAM 7.

The control unit 11 displays the contact position on the liquid crystal display 6 when the contact position detected on the touch panel 2 is not yet displayed on the liquid crystal display 6, and the contact position detected on the touch panel 2 is displayed. When the position is already displayed on the liquid crystal display 6, the display of the contact position is erased on the liquid crystal display 6.

The input pen 1 is like a general ballpoint pen which is not controlled by any means as an input means. The touch panel 2 is a matrix of m × n, and in this example, a transparent thin film resistance type is used. The touch panel 2 is provided with an input signal conversion unit 9 for transmitting a signal from the touch panel 2 to the CPU 4. A liquid crystal display driver 10 for driving the liquid crystal display 6 by the CPU 4 is attached to the liquid crystal display 6.

The CPU 4 inputs a signal from the input pen 1,
The liquid crystal display 6 is controlled, the input data is converted to external character data, and the converted external character data is transferred to the personal computer 3 or the like. The ROM 5 stores programs for executing these processes. RAM
Input data from the touch panel and data after conversion of external character data are stored in 7.

Since the external character registration function exists in the personal computer 3, the pen input type external character creating apparatus of the present invention is used only for creating external character data. The CPU 4 executes the RS by the external character registration program on the personal computer 3 side.
-Controlled via 232C port 8.

Next, the operation of the pen-input type external character creating apparatus according to the present invention will be described. FIG. 2 is an external view showing an embodiment of a pen input type external character creating device according to the present invention, and FIG. 3 is a side view of a main part of FIG. Hereinafter, description will be given with reference to FIGS. 1 to 3.

The pen-input type external character creating apparatus 200 is of a size that can be placed on a desk, and below the touch panel 2 is a liquid crystal display 6 which is the same matrix as the touch panel 2. When the touch panel 2 is touched by the input pen 1, the touch position P is detected by the touch panel 2 and input to the CPU 4.

The CPU 4 determines whether or not the contact position P is already displayed on the liquid crystal display 6 based on the data in the RAM 7 or the like. If the contact position P is not displayed,
The CPU 4 causes the liquid crystal display 6 to display the contact position P. If the contact position P is already displayed, the CPU
Reference numeral 4 erases the display of the contact position P on the liquid crystal display 6.

As described above, the input pen 1 is attached to the touch panel 2.
Since the control unit 11 controls to display or erase the contact position P by touching with, the external character can be created only with the input pen 1 as an input tool. Therefore, it is possible to eliminate the key operation required when creating an external character with the conventional device, and improve the operability.

After the completion of the external character, the "confirm" key 214 is pressed to convert it into external character data, and the "transfer" key 215
External character data is transferred to the personal computer 3 by pressing.

[0022]

As described above, according to the present invention, the control section displays or erases the contact position only by touching the touch panel with the input pen, so that the external character can be created only with the input pen. . Therefore, the key operation required in the conventional device can be eliminated, so that the operability can be improved and the external character creation work can be made efficient.

If a liquid crystal display is used for the display section, the pen-input type external character creating device can be made highly precise and thin.
