【Example】

 FIG. 1 is a block diagram showing the functional arrangement of an embodiment of the online character recognition device of the present invention. In the figure, 3 is a handwriting data input unit, which is composed of a display-integrated type tablet 1 shown in FIG. 2 and receives handwriting data.

Reference numeral 4 denotes an input data determination unit, which determines whether the coordinate information of the writing data input from the writing data input unit 3 indicates whether it is input in the character entry frame or in the instruction area of the character entry frame format. It is determined whether or not it has been input, and based on the result of the determination, the writing data input to the stroke management unit 6 such as the character entry frame and the writing frame format changing unit 5 in the case of the format designation area is sent.

A writing frame format changing unit 5 determines which writing frame format changing area is designated by the writing data input via the input data determining unit 4 and creates a format corresponding to the instruction. The format of the writing frame is changed, and the writing frame display unit 8 displays it on the panel surface 1c of the tablet 1 based on the format information. A stroke management unit 6 is mainly composed of a RAM and stores the writing data input through the input data determination unit 4.

A character recognition processing unit 7 includes a character recognition processor and the like, and recognizes a character based on the writing data stored in the stroke management unit 6. This character recognition method is not particularly limited. Reference numeral 10 denotes a recognition result display unit, which allows a character code, which is a recognition result of the character recognition processing unit 7, to be displayed on the panel surface 1c of the tablet 1 through a processing unit such as a document processing device that manages document information. Display at the input position.

Reference numeral 9 denotes a handwriting data display unit, which displays handwriting on the basis of the handwriting data stored in the stroke management unit 6 in the corresponding handwriting frame of the handwriting frame provided on the panel surface 1 c of the tablet 1. In addition, the handwriting of the character whose recognition result has been input on the recognition result display unit 10 is erased. In the present embodiment, the writing data input unit 3, the writing frame display unit 8, the writing data display unit 9, and the recognition result display unit 10 are 3, when the display-integrated tablet has a structure different from the main body. 8 and 10 can be considered as an interface between the main body and the display-integrated tablet.
