Abstract

PURPOSE:To shorten time required for typing by recognizing the form of a character drawn by a handwriting input, and performing printing operation according to the recognition information. CONSTITUTION:In a handwriting input register 82, sensor points of a character form drawn on a sensor group 12 are stored successively after being converted into codes, and they are compared with patterns in a standard pattern memory 91 through a comparing circuit 92 to make a decision. The character form after the decision is stored in an input memory RAM96 for display in the form of character pattern signals 97-99. Those character form pattern signals are converted by a trailing character form generating circuit 110 into dot signals, which are displayed on a handwriting display part 13 as a character. Further, a converted character form generating cuicuit 111, a converted character form selecting circuit 112, a print display part 14, and a dot conversion part 113 form a complete sentence, which is printed by a printing head 2.

Description

[Detailed description of the invention] The present invention relates to handwritten typewriter devices.

Devices conventionally called typewriters, character display devices,
For example, all character input devices displayed on cathode ray tubes and the like perform printing and display by hitting predetermined character keys. Therefore, there are many keys for letters, numbers, symbols, etc., and it is difficult for people who are not used to it to find the key positions, and it is especially difficult for ordinary people to use kanji typewriters. Extremely. A word processor is one way to solve this problem, but it is expensive and requires input of at least kana characters, and if you include numbers and alphabets, there are more than 100 characters to choose from.
I needed to let go of the person I was looking for.

The present invention relates to a device that is provided with a plurality of sensor terminal groups, and that determines the shape of a character drawn thereon, generates a character symbol, and operates display or printing. Once this is completed, it is easy to convert the old display to kanji using a word processor, and it is also possible to immediately identify kanji and print or display by increasing the number of terminals per sensor. It is. A detailed explanation will be given below with reference to the drawings.

FIG. 1 shows a perspective view of the printing section of a conventionally used dot printing device. While the dot print head 2 scans the paper surface 1, the dot bin is printed by the print signal input from the print input code 3. 4 presses the paper surface 1 and prints 5; it is an example of a printing device that can be used in the present invention.

FIG. 2 is a perspective view showing an example of the handwriting input device of the present invention. On the top surface of the case 11, there is a sensor terminal group 12 configured in a matrix, on which the handwritten character shape is identified, and the character The generated characters are converted into a printed character pattern, and the drawn characters are displayed on the handwritten display section 13. Print display.

The section 14 is used when converting the text displayed on the handwriting display section 13 into kanji or making corrections.
In this embodiment, characters drawn in hiragana and uppercase letters are shown modified into kanji and lowercase letters. In order to simplify the drawing, the display section in this figure is displayed with about 20 characters, but it is possible to use more character strings, lines, ゛, or use separate cathode ray tubes, for example, to display dozens of characters. It is also possible to type each chapter on the printer shown in FIG. 1 after it has been completed. 15 is a character shape completion key, and the sensor terminal group 12
When one glyph drawn on the screen is completed, the glyph discrimination circuit starts operating, displays the glyph, and at the same time shifts the bar 10 indicating the position to be displayed to the right, and selects the next position to be displayed. clearly indicate. 16 is a left shift key, which is a key to shift bar 16 to the left; 17 is a character deletion key, which is a key to erase characters in bar 10; 18 is a character shape conversion key, which is used to shift one or more characters specified by bar 10. A key that commands to convert and display the character shape into kanji, katakana, alphabetic characters, etc.
Key 19 is a left shift key, key 2o is a right shift key, and the character shape conversion key 18 is used to select one character from a plurality of kanji, lowercase letters, etc. displayed on the conversion display section 21 by moving the bar 22. , key 23 is a print command key,
The print display section 140 characters are outputted via the output cord 24 to the first
This is the key to output to the printing device shown in the figure. These key groups in this figure show an example of the ice-water operation, and as the display area increases, change one line, insert a phrase, change the number of printed characters, and change the number of n lines. It is necessary to add a key such as "Shift". Further, instead of the above-mentioned mechanical key, it is also possible to use one sensor terminal, or to use it in combination with the sensor one terminal group 12 for command input.

FIG. 3 is an enlarged view of one terminal group of the sensor shown in FIG. 2. The sensor terminals 31 to 65 are arranged in a matrix as shown in the figure, and the movement of, for example, a fingertip passing over these sensor terminals is converted into an ON/OFF signal, and it is determined which terminal is connected to the side of the character shape. It is possible to know what is composed of. As a sensor terminal, a metal terminal is used to apply earth input from the human body or the induced voltage of the human body, a capacitor terminal is used for electrostatic coupling, a photo sensor is used for optical coupling, a coil sensor is used for magnetic coupling, etc. The method can be selected depending on the device.

Figure 4 is an example of a circuit diagram of the sensor terminal group in Figure 3.
This is a method of creating input by grounding with your fingertips. When the finger T1 touches the sensor terminal 31A and the ground terminal 72, the terminal 31B, which is connected by the high resistance 73,
The voltage becomes the ground potential, and the waveform becomes as shown in a waveform 74. The capacitor 75 is for noise cancellation and suppresses coupling between one terminal of the sensor. The waveform 74 is amplified into a waveform 76 by an inverter 75, and shaped into a waveform 78 by a one-shot circuit 77. The other sensor terminal groups are similarly configured as shown in the sensor terminal 6.5 A, one-shot circuit 80, and are input to the encoder 81.
After being converted into a binary code, it is stored as a bit signal in the handwriting input register 82 for character shape determination. The one-shot circuits 77, 80, etc. serve both to prevent fingertip chattering and to shape the input of the encoder 81.

FIG. 5 is a diagram of the shape of the sensor terminal group shown in FIG. 3 when drawn in hiragana. Figure 5 (A) shows the hiragana “ka”,
The hiragana "n" is drawn in the figure (B) and the hiragana "ji" is drawn in the figure 5 (C), and the sensor terminals 31 to 65 respectively
The state in which one of the following is ON is indicated by a black frame. The moment each sensor terminal is touched by a fingertip, a binary code is generated by the encoder 81 shown in FIG. For example, it is possible to determine which sensor point and which sensor point are combined to form a "side" of a character.

FIG. 6 is a circuit block diagram of the handwriting input device of FIG. 2. Handwriting input register 82 explained in FIG.
In this case, one sensor point for each character drawn in the sensor terminal group 12 is code-converted and stored sequentially, and the combination of these adjacent sensor points matches which character shape in the standard button memory 91. It is determined by the comparison circuit 92 whether the In the standard baton memory 91, it is necessary to convert all combinations of drawn glyphs and symbols, as well as the peculiarities of glyph shapes that differ depending on the person drawing them, into binary codes and register them. The binary code conversion referred to here means the binary code obtained by code converting the glyph drawn on the sensor terminal group 12 and the binary code of each glyph stored in the standard button memory 91. This means that the codes are converted and stored as bit signals so that they can be compared in the same permutation. Therefore, sensor one terminal group 1
For the glyphs marked in 2, a matching glyph can be found from the glyph group 95. ° These judgments are stored in the form of the letter-shaped bang signals 97 to 99. These * character shape slam signals are converted into segment signals as well as dot signals by the next character shape generation circuit 110, and are displayed as characters on the handwritten display section 13 of FIG. The characters displayed on the handwritten display section 13 are displayed in the section controlled by the bar 10 in FIG. , kanji, and other characters. Examples of converted glyphs for the kana character "ji" are shown as glyph bang signals 115 to 117. The characters displayed on the conversion display section 21 are selected by the left shift key 19 and the right/left key 20 as explained in FIG.
12 is displayed on the print display section 14. Each character on the print display section 14 is a sentence that will be printed after the character shape conversion has been completed, and the print command key 23 drives the dot conversion circuit 113 and sends a print signal to the print head 2 shown in FIG. It is designed to give

If the printhead is a type selection head, the dot converter port vi11113 must be made into a type selection circuit to pick up the matching type.

As described above, the present invention recognizes the character shape drawn by handwriting input, displays the character on the handwriting display section, converts the character into another character as necessary, and converts the character into a complete sentence. This invention relates to a device for printing, and the time conventionally required to select character keys on a typewriter can be significantly shortened. Furthermore, by increasing the number of sensor terminals, it is possible to directly recognize kanji, lowercase English letters, cursive, etc., and by using the means of the present invention, anyone can create typed text. This makes it easy to write and edit.
