Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a single character/figure input device, and particularly to a character/figure input device suitable for easily inputting characters, figures, etc.

[Background of the invention]

Conventionally, as a method for inputting single character/graphic information, there is known a method of inputting information by specifying and selecting it using a light pen, digitizer, or the like. They cannot be used so multifunctionally as to eliminate the need for a keyboard, but are used secondary or partially, and are used in conjunction with a keyboard or other information input device I (tablet, etc.).

However, if you can make this keyboard unnecessary,
It is certain that the operability of the device will be greatly improved.

As an example of this type of input device, as shown in Japanese Patent Application No. 54-522, a touch panel is created by providing a transparent electrode on a CRT screen, and input of coordinates, etc. is made by touching the touch panel with a finger or the like. There are things that can be done.

Since this method uses a pressure sensing method using a finger or the like, there are restrictions on the number of patterns that can be displayed at one time, and there is a problem in subdividing the patterns.

[Purpose of the invention]

The purpose of the present invention is to improve such conventional problems, increase the number of input pattern categories, improve the operability of the device,
Another object of the present invention is to provide a character/figure input device that greatly reduces the number of parts and improves the reliability of the device.

[Summary of the invention]

In order to achieve the above object, the present invention provides a key code for inputting one character/graphic information, a character/symbol pattern generator that generates a character/symbol pattern corresponding to the key code, and a display of the character/graphic information. In a character/figure input device having a CRT display and a detector for reading position information of the key code, selection of displaying selection information such as various types of characters and figures to be input by key codes on the screen of the CRT display. display means,
A search information display means for displaying search information such as input characters and figures using a key code, and storing the selection information and key code position information of the search information in correspondence with the character/symbol pattern of the character/symbol pattern generator. The detector is positioned at the key code of the selection information and search information displayed by the selection display means and the search information display means, and by turning on the switch of the detector, character/graphic information, etc. is characterized in that it is input at the cursor position on the CRT display.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

- a block diagram of the human power device;

In FIG. 1, as memories for displaying on a CRT display 1, a memory for image information 8, a memory for search information 9, and a memory for function selection information IO are provided and connected to a microcomputer 5. The contents of these information memories are transmitted via a CRT control unit 4 that controls the CRT display 1, a parallel-serial conversion circuit (P-8 conversion circuit) 3 that converts memory information data, and then a video signal generation circuit 2. connected to the CRT to become a video signal.
A detector 12 is connected to the display 1 and displayed on the screen (see FIG. 2 described later), and also reads optical information from characters, symbols, and other patterns displayed on the screen of the CRT display 1. A coordinate detection circuit 11 for detecting the display position (coordinates) of is provided, and this signal is connected to the microcomputer 5. The microcomputer 5 is provided with a data register 6 for storing various data and a mode register 7 for storing mode information.

FIG. 2 is an example of a screen display on a CRT display l.

Here, the display contents on the CRT display 1 are comprised of an image information display section 1a, a search information display section 1b, and a function selection display section 1c.

The image information display section 1'a displays text/figure information to be input, the search information display section 1b displays information (key code, etc.) for searching for the text/figures to be input, and the 1-function selection display section 1c displays information for searching for text/figures to be input. Type 1 of characters to be input: Figures, symbols, etc. are displayed.

Next, the operation shown in FIG. 1 will be explained.

The contents from the image information memory 8 are transferred to the microcomputer 5, CRT control section 4. The signal is displayed on the CRT display l through the P-3 conversion circuit 3 and the video signal generation circuit 2.

This is displayed on the image information display section la in the upper half of the screen of the CRT display 1 shown in FIG. In the six-line display example, the user looks at this screen and selects and inputs the character to be input at the cursor position from the search information display section 1b.In the six-line display example, the user is trying to input the kana character "Hitachi".

Since ``1'Hita'' has already been input, the next character to be input is the katakana ``CH''. First, the user uses the detector 12, such as a light pen, to check the character displayed at the bottom of the CRT display l. From the function selection display unit IC, place the detector 12 on a kana character, turn on the switch 13 of the detector 12, and shine light on it.The coordinate detection circuit 11 detects that the kana character has been selected, and the signal is detected. Send it to microcomputer 5. Mode information for kana characters is input to the mode register 7. Furthermore, according to the contents of this mode register, kana characters are selected from the search information memory 9 on the search information display section 1b, and the kana characters are displayed as shown in FIG. Therefore, the user uses the detector 12 to
, and display the kana character pattern in the image information display section 1a.
By displaying the key code at the cursor position, the key code corresponding to the kana character "chi" is written into the data register 6, and written into the image information memory 8 by the microcomputer 5.

Thereafter, similarly, character types are arbitrarily selected and input using the mini function selection display section 1c.

The search information memory 9 is called a character generator, and includes a character generator 9 for kana characters.
In addition to a, alphanumeric characters, kanji, and symbols.

It goes without saying that if patterns such as figures are registered in advance, they can be displayed on the CRT display 1. It goes without saying that scrolling etc. of 1a can also be specified.

In this manner, according to the present embodiment, it is possible to arbitrarily set and input special symbols, special patterns, etc. in addition to commonly used alphanumeric characters, kana characters, kanji characters, etc. Furthermore, even in the case of a single display device, the content of the character generator can be changed and set arbitrarily depending on the frequency of use and operability of the user. Furthermore, in response to the demand for miniaturization of devices, since an input device such as a keyboard is no longer required, the number of semiconductor components can be significantly reduced, which has the effect of improving device reliability and reducing costs. Also, touch panel
It also becomes possible to subdivide the sensing part, which was a problem with J, etc., and the amount of information input can also be increased.

〔Effect of the invention〕

As explained above, according to the present invention, the types of input pattern categories are increased, the operability of the device is improved,
Moreover, the number of parts can be significantly reduced and the reliability of the device can be improved.
