When the pen-off is detected for a certain time when the characters are written in from both directions as shown in "Last year result" 403 and "(Activity by section)" 406 of this figure, the handwriting data written immediately before is written. When the control section 24 cuts out the image, and based on the determination result of the window orientation determination section 26, the handwriting data coordinate conversion section 28 performs coordinate conversion so that the direction is the positive direction, and the direction is determined to be the positive direction. If it does, it is sent to the recognition unit 27 as it is and recognized. Then, the recognition result is output to the writing position.

In this embodiment, only the input of characters has been described, but other recognition targets such as figures and symbols can be processed in the same manner. FIG. 5 is a diagram showing a display state of the display device according to the embodiment of the present invention. In the figure, 501 and 504 correspond to 401 and 404 in FIG. 4, and the same document data is displayed in both windows although the orientations are different.

502 and 505 are 401 and 4 in FIG.
It is the same as 05. When "Last year" 503 or 506 in this figure is written in one window, the handwriting is displayed in the other window. When the pen-off is detected for a certain period of time, the handwriting data written immediately before is cut out by the control unit 24, and based on the determination result of the window orientation determination unit 26, when the orientation is determined to be the reverse direction, the handwriting data coordinate conversion unit. The coordinate conversion is performed so that the direction is the normal direction at 28, and when it is determined that the direction is the normal direction, the coordinates are directly transmitted to the recognition unit 27 and recognized. Then, the recognition result is output to the writing position, and the recognition result is also output to the other window corresponding to the position.
