Abstract

PURPOSE:To use wholly the tablet as the area only to write characters by providing plural types of the input pen in accordance with the type of the input character and constructing it so as to be able to recognize the type of the character by the used pen. CONSTITUTION:To a tablet control part TC 4, a tablet TAB 5 and a pen control part PC 6 are connected and to the PC 6 an input pen 7a for Chinese characters, an input pen 7b for HIRAGANA (cursive form of Japanese syllabary), an input pen 7c for KATAKANA (Japanese syllabary) and a pen 7d for writing alphameric characters are connected. A CPU 1 reads the data from the TC 4 and PC 6 and discriminates whether or not the characters are written based upon these data. When the characters are written, the CPU 1 discriminates with which pen out of input pens 7a-7d the characters are written through the PC 6. Respective input characters are inputted from the hand-written character recognizing device of the online. Without providing the recognizing area in accordance with the kind of the input character on a TAB 5, the type of the characters can be recognized and the input work can be made simple in correspondence to the type of the pen.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a handwritten character recognition device, and more particularly to a handwritten character recognition device that has a plurality of input pens and distinguishes the type of character depending on the type of pen. It is.

[Prior Art] In a conventional online type handwritten character recognition device, the type of input character, for example, a kanji character.

It was difficult to distinguish between hiragana, alphanumeric characters, etc.

Therefore, in the past, in order to distinguish the type of character,
Create an area on the tablet where you draw characters to specify the recognition mode according to the type of character, or an area to specify the priority order when similar characters occur, and enter an area that indicates the type of character you are about to input. A method was adopted in which the information was specified using a pen and then entered.

In addition to these methods, types of characters that are difficult to recognize,
For example, hiragana, katakana, symbols, alphanumeric characters, etc. are all arranged on the tablet, and when entering these characters, a pen-touch input method is sometimes used in which characters are directly selected with an input pen.

Even if any of the above-mentioned methods is adopted, an extra area must be provided on the tablet, and as a result, the input work becomes extremely complicated.

[Purpose] The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and instead of providing areas on the tablet for different types of characters, the entire tablet is used as an area only for writing characters. It is an object of the present invention to provide a handwritten character recognition device configured to be usable.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 is a block diagram of the control circuit of the entire device. In the figure, the reference numeral 1 is the central processing unit (CPU).
The overall control operation is performed as described below.

This CPU is connected to a third address via an address and data bus 8.
A random access memory (RAM) 3 used in the ROM 2 is connected to a read only memory (ROM) 2 in which a control program according to the flow chart shown in the figure and a program for character recognition processing are stored.

Further, the one indicated by reference numeral 4 is a tablet left control section to which a tablet 5 is connected.

A pen control unit 6 is connected to the tablet control unit 4, which includes a kanji input pen 7a and a hiragana input pen 7.
b, a katakana input pen 7C and an alphanumeric symbol input pen 7d are connected.

As shown in FIG. 2, the tablet 5 is formed into a flat plate shape, and a grid-like character input area 9 is formed on its top surface, and one character is written in each square of this grid. There is.

A pen control unit 6 is housed within the tablet 5, and the input pens 7a to 7d described above are connected to this via lead wires IO. Then, the pen control unit 6 determines which of the input pens 7a to 7d is being used.

Next, the operation of this embodiment configured as described above will be explained with reference to the flowchart shown in FIG.

First, in step SL, data is read from the tablet control section 4 and pen control section 6, and in step S2, it is determined based on these data whether or not a character has been written.

If a character has been written, the process advances to step S3, and a step is entered in which the pen control unit 6 determines which of the input pens 7a to 7d was used to write the character.

Then, in steps S4 to S6, it is sequentially determined whether the pen is for kanji, hiragana, or katakana, and if the pen is for kanji, step S7. If it is for hiragana, the process goes to step S8, and if it is for katakana, the process goes to step S9. In step S10, each input character is input from an online handwritten character recognition device.

If the pen is not a kanji, hiragana, or katakana pen, it is recognized in step 311 as an alphanumeric symbol and output in step SIO.

Thereafter, the same operation is repeated, and the recognition operation is repeated for each input character.

Since this embodiment adopts the structure described above, it is possible to recognize the type of character according to the type of pen without creating a recognition area on the tablet according to the type of input character, thereby simplifying the input work. greatly simplified.

In the above-mentioned embodiment, the number of input pens is four, and each pen is separate. However, it is possible to write multiple types of characters with one pen, for example
You can change the type of letters by changing the tip of the pen using a click type like a colored ballpoint pen.

[Effects] As is clear from the above description, according to the present invention, a structure is provided in which a plurality of types of input pens are provided according to the types of input characters, and the type of character can be recognized by the pen used. This eliminates the need for the conventional work of setting up recognition areas for each type of character on the tablet and inputting characters while specifying the area, greatly simplifying the input process.
