The writing stroke in 2-1 is extracted for each character and character recognition is performed. The recognition character memory 12-2 temporarily stores the character code converted by the character recognition as a recognition character, and the recognition character is sent to the display unit 3 and displayed as a candidate. Here, when the next candidate key or the previous candidate key is operated, the recognition character is switched accordingly. The input character memory 12-3 is used to transfer the recognized characters from the recognized character memory 12-2 as determined characters when the recognized characters to be displayed as candidates are determined. Retained until termination. The field definition memory 12-4 stores field definition information for defining a handwriting input area (character recognition field) for each character on the tablet 2 according to the form format.

FIG. 3B shows various files and tables stored in the storage device 13. The recognition dictionary file RG stores a character pattern and a character code in correspondence with each character unit. Refers to the recognition dictionary file RG when recognizing a writing stroke entered in a character recognition field set on the tablet 2 and converts the writing stroke into a corresponding character code. The attribute determination table AT is a table for determining the character attribute of the recognized character. The CPU 11 inputs and specifies the character attribute of the recognized character on the tablet 2 located near the upper side of the character recognition field in which the writing stroke is written. Attribute designation area (rectangular attribute designation field) is newly set, and when a predetermined stroke is entered in this attribute designation field, the attribute discrimination table AT
And converts the stroke into a character attribute corresponding to the type. Here, the predetermined stroke is a symbol stroke having a predetermined shape. When the symbol stroke is written, the symbol is not recognized as a character, but is determined in advance according to the shape (type) of the symbol. This is a simulated stroke for designating a predetermined character attribute. Hereinafter, a stroke for designating a character attribute is referred to as a stroke gesture. FIG. 4 shows the contents of the attribute discrimination table AT. As the types of stroke gestures written in the attribute instruction field, as shown in FIG.
Horizontal lines, mountain fold lines, valley fold lines, upper right diagonal lines, and right lower diagonal lines are defined. Underline, shading, emphasis, inversion, and side point are assigned as character attributes corresponding to each stroke gesture.
The document file TX is a text memory that stores and holds text data together with character attributes for each form, and the contents are transferred to another computer. Form format file FM
Stores the format format for each type of form. When an arbitrary form is input and designated, the format format is read and set in the field definition memory 12-4.

Next, the operation of the handwriting data processing device will be described with reference to the flowchart shown in FIG. Here, a program for realizing each function described in this flowchart is stored in the storage medium 14 in the form of a program code readable by the CPU 11, and its contents are loaded into a work memory in the RAM 12. ing. FIG. 5 is a flowchart showing the main operation of the handwriting data processing device. First, in a state where an arbitrary form 5 is fixed on the tablet 2 by the clip 6, when the type of the form 5 is selected and designated (step S1), the form format corresponding to the type is changed to the form format file FM.
Is read from the field definition memory 12-4 and set in the field definition memory 12-4, and a character recognition field is set for each character on the tablet 2 based on the contents of the field definition memory 12-4 (step S2). In this state, a state of waiting for a key input from the keyboard 4 is set.

Now, when the tablet input key is operated to start filling in the form 5, it is detected in step S3 and the process proceeds to step S4 to enable the stroke input to the tablet 2. Here, when a stroke is input, the stroke data is sequentially stored in the stroke data memory 12-1 as it is (step S5), and the contents of the stroke data memory 12-1 are sequentially analyzed (step S6). . As a result,
It is determined whether the input is a stroke input into the attribute instruction field (step S7) or a stroke input into the character recognition field (step S8). If the current stroke input is not entered in the character recognition field, the current stroke input is invalidated (step S13), but as shown in FIG.
Are formed by printing a plurality of character entry frames 5a. When, for example, a kana character "a" is entered in the first character entry frame 5a, the character entry frame 5a is set on the tablet 2 corresponding to the character entry frame 5a. It is detected in step S8 that the stroke is input into the character recognition field. Then, a writing stroke is cut out from the character recognition field as data for one character (step S9), and character recognition is performed by referring to the recognition dictionary file RG based on the writing stroke, and the recognized character code is converted to a recognized character. It is set in the memory 12-2 (step S10). Then, the recognition character is sent to the display unit 3 for display and output (step S11), and an attribute indication field is assigned to a position near the upper side of the character recognition field in which the current handwriting stroke is written (step S12). Then, returning to step S3, the above operation is repeated every time the tablet input key is operated and a character is entered in the character entry box 5a in the form 5.

FIG. 6B shows a case where the characters "A", "I",... "O" are sequentially entered in each character entry box 5a of the form 5, and the tablet 2 corresponding to the character entry box 5a. A rectangular attribute indication field indicated by a broken line in the figure is assigned near the upper side of each of the above character recognition fields. FIG. 7A shows the contents of the recognition character memory 12-2. The recognition character memory 12-2 performs recognition corresponding to the frame numbers (1, 2,..., N) indicating the character entry frames 5a on the form 5. In addition to storing a character code, a character attribute designated corresponding to the recognized character is stored. In this case, the frame No.
As recognition characters corresponding to (1, 2,..., 5), “A,
I ......... O "is stored. FIG. 8A shows a display state in this case, in which the recognition characters “A, I,... O” are displayed.

Here, the writer cannot actually visually confirm the attribute instruction field, but is aware that the attribute instruction field exists on the tablet 2 near the upper side of the character entry box 5a. Write a stroke gesture according to the type of attribute in the vicinity. Then
In step S7, since it is detected that the entry is in the attribute instruction field, the stroke gesture written in the field is cut out (step S7).
14) Referring to the attribute determination table AT based on the stroke gesture, the designated attribute is recognized (step S15). Now, as shown in FIG. 6 (C), assuming that five horizontal lines are respectively written near the upper side of "Oh,..." In each character writing box 5a, an underline is used as a character attribute. The recognized characters are assigned to the recognized character memory 12-2 as attributes of the recognized characters (step S16), and the character attributes are added to the recognized characters and displayed (step S17). FIG.
FIG. 8B shows the contents of the recognition character memory 12-2 in this case, and FIG. 8B shows the display contents.

On the other hand, as shown in FIG. 6 (D), if it is assumed that a mountain-fold line is written near the upper part of "Oh,... Shading is recognized. FIG. 8C shows a display state in this case. When such attribute designation is completed, the process returns to step S3 and waits for a key input. Here, assuming that the enter key has been operated, step S3
Is detected, the process proceeds to step S17, and the contents of the recognized character memory 12-2 are transferred to the input character memory 12-3. If it is assumed that the end key has been operated to indicate that writing of one form has been completed, the process proceeds to step S18, where the contents of the input character memory 12-3 are stored in the document file TX and registered and saved. Is done.

As described above, in this writing data processing apparatus, a writing stroke entered in a character recognition field set on the tablet 2 in accordance with the form format is recognized, and the recognized character is displayed and output. An attribute indicating field for inputting and specifying the character attribute of the recognized character is set in the vicinity of the character recognition field where the writing stroke is written, and when a predetermined stroke is written in this attribute indicating field, Based on the attribute discrimination table AT, the converted character attribute is converted to the corresponding character attribute, and the converted character attribute is added to the recognized character. , Character attributes can be easily added to recognized characters. in this case,
The attribute designating field is set in the vicinity of the character recognition field each time a writing stroke is entered in the character recognition field and recognized, so that the attribute can be designated each time one character is written. Tablet 2
In the method of placing the form 5 on the form 5 and filling in the form, even if the attribute form is not printed on the form 5, the character form 5
A character attribute can be specified only by writing a stroke gesture corresponding to the type of attribute near a.
