Abstract

PURPOSE:To execute easily the operation by specifying a display position of a character displayed on a CRT by a movement of a signal detecting pen, and inputting a signal corresponding to the character concerned by this specifying signal. CONSTITUTION:In case an information input device is in an external character input state, an external character is displayed at a prescribed interval on a CRT picture 10, a pulse is applied successively to each electrode line X, Y through an X decoder 3 and a Y decoder 4, and also a cursor is displayed on the lower end part of a character display area on the CRT picture 10. When the cursor is displayed on the lower part of a desired external character, when a signal detecting pen 7 is made to abut on a digitizer 1 at a position of its digitizer 1, a switch 8 becomes on, and a device becomes a point mode. When the device becomes this point mode, a character code displayed in accordance with a position where the cursor is displayed is inputted, and stored in a sentence storing circuit 14.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the control of a Japanese word processor as an information input device used for OA.

(Prior art) In recent years, Japanese word processors have become one of the ways to use computers.In Japanese word processors, there are those that input kanji directly with a penta or chi, and those that use keyboard keys (alphabet, katakana, etc.). ) is used in practice. Among these Japanese word processors, 2,000 to 3,000 characters are displayed on one normal character sheet in those that input by touching the detection pen on the character sheet. Once the level was accommodated, other characters could not be displayed.

Therefore, characters that cannot be accommodated in two character sheets are called custom characters and are displayed on another character sheet, and the character sheet is exchanged when entering custom characters.

Devices that key in JIS codes and the like have been devised and are in use.

(Problems to be Solved by the Invention) The present invention uses a signal detection pen and a tufflet on which a character sheet is recorded. 1. Replacement of character sheets in inputting external characters in a Japanese word processor.

Alternatively, the present invention relates to an information input device that eliminates frequent operations such as inputting external character codes.

(Means for Solving the Problems) The present invention provides a plurality of electrode wires arranged in the coordinate axis direction, means for sequentially applying pulses to the plurality of electrode wires, and capacitive coupling with the applied pulses. An information input device comprising a signal detection pen, 2 means for inputting information based on the detection signal of the signal detection pen, and 2 a CRT as a display means, the display position of a character displayed on the CRT being determined by the signal. Identification is made by moving the detection pen, and this identification signal is used to input the character corresponding to the character.Using one character sheet with the information input device, displaying external characters on the CRT and inputting two internal characters.Detection This is for inputting external characters using a pen.

(Example) Digitizer as a tablet with multiple electrode wires
1 and the signal detection pen 7 will be explained with reference to FIG. X electrode wire X i arranged in the X-axis direction of the digitizer 1.

Between Xi+1, a signal detection pen is located at a distance between Xi and d+ and between Xi+1 and 62, and pulses are sequentially applied to this X electrode line XL Xi+1. At this time, the signal detection pen 7 and each of the X electrode lines Xi, Xi+1 are capacitively coupled, and detection voltages V+, V2 are detected at respective timings with values substantially inversely proportional to respective distances d+, d2.

Moreover, the relationship between the detection signal voltage of the signal detection pen 7 and each electrode line Xi, X++1 is expressed by the following approximate expression d+'/V
It is expressed as +-α·d2/V2. (However, α is a coefficient.) The coefficient is determined by substituting the actual measured value using this equation. Positioning is performed using detection voltages corresponding to two or three of these adjacent electrode lines, and the resolution in this method is usually 0.1111 m, but if even more precision is required, It can also be determined from the correction data conversion table 5Vc shown in FIG.

Next, the actual input of external characters will be explained. When an internal character is selected by a switch or function key (not shown), the character codes of the character sheet displayed at the position touched by the signal detection pen are sequentially input. This internal character input can be input using a conventional information input device, so a description thereof will be omitted. When inputting external characters, a switch or a function key (not shown) is touched, and the information input device enters an external character input state, and the external characters are displayed at regular intervals on the CRT screen. The method for displaying external characters on the CRT screen is as follows: 1. As a normal CRT control, data is read from the character font memory 11 shown in FIG. It applies data.

In this external character input state, this information input device is in two states: point mode and stream mode. The point mode is a mode in which desired external characters are input by signal detection by the signal detection pen 7 and a signal when the switch 8 built in the signal detection pen 7 is directly connected to the digitizer 1. What is stream mode?

In this mode, a position signal is input when the signal detection pen 7 approaches the digitizer to control the movement of the cursor 15 (see FIG. 3) on the CR1 screen. Now, when this information input device enters the external character input state by operating a switch or a function key (not shown), it enters the stream mode, and external characters are displayed at predetermined intervals on the CRT screen 10, and each electrode line X decoder 3 for X and Y. Pulses are sequentially applied via the X decoder 4, and CR
T below the letters (surname in Figure 3) displayed in the upper left corner of 1o on the screen.

A cursor 156 is displayed at the lower end of the character display area 16. When the tip of the signal detection pen 7 approaches the surface of the digitizer 1 in this state, the position signal detected by the signal detection pen 7 is applied to the control circuit 2, and this signal is transmitted to the digitizer 1 of the detection pen 7. The corresponding position signal is applied to the output vanofer B via the correction data table 5.

On the CRTiO, force-runs 15 are sequentially displayed at the corresponding positions. When the cursor 75 moves to the lower part of the desired external character and is displayed, the signal detection pen 7 is brought into contact with the digitizer 1 at that position. By touching the digitizer IK signal detection ben 7, the switch 8 is turned on and the point mode is set. When the point mode is entered, the character code displayed corresponding to the position where the cursor 15 is displayed is input and stored in the nine-sentence storage circuit 14. Next, the signal detection pen 7 is separated from the digitizer 7, the switch 8 is turned off, and the signal detection pen 7 is brought into contact with the digitizer again, and the switch 8 is turned on.
No character code is input until , and the input state returns to the stream mode, and a pulse is applied to each electrode line to wait for the input of a non-standard character, that is, to enter a character specifying state. If a custom character is to be further input, the signal detection ben 70 is moved closer to the digitizer 1, the cursor 15 on the CRT screen is moved, and the custom character is input in the same manner as in the previous procedure. When inputting internal characters after inputting external characters, press the switch or function key (not shown) on the CRT.
The previously input text and the newly input external characters are displayed on the screen, allowing the user to confirm the input of the external characters and enter additional text. Although the input part has been explained so far as a digitizer, except for specific characters when inputting external characters (stream mode), detection position accuracy is not required very much, so the resolution of about 6 mm pitch of a normal tablet is used. It is enough.

(Effects of the Invention) Since the present invention is configured as described above, a character sheet for external characters is not required, and the operation of the 2-Japanese word processor is facilitated.
