Subsequently, in step S3-2, when the operator operates the keyboard 2-16 or the pen 2-18 to select an item, the process proceeds to step S3-3.

Then, in step S3-3, the next process is determined according to the item selected in step S3-2. Here, if the release button 8-2 shown in FIG. 23 is pressed, the process proceeds to step S3-11 without changing the settings, ends the handwritten character input condition setting, and returns to the main flow. On the other hand, if the operator selects the handwritten character input frame number setting 8-3 shown in FIG. 23 in step S3-2, the process proceeds from step S3-3 to step S3.
Proceed to -12.

In step S3-12, a handwritten character input frame number setting window 8-4 is displayed (see FIG. 24).
At this time, the currently set contents are displayed.

Subsequently, in step S3-13, when the number of character input frames to be changed is input by the operator, the flow advances to step S3-14.

If the release button 8-5 is pressed, the process returns from step S3-14 to step S3-2 without changing the setting of the number of handwritten character input frames.

In step S3-14, it is determined whether the input number of frames is within the valid range. In this state,
As shown in FIG. 24, the number of horizontal frames = 4.

Here, when the number of horizontal frames is set to 3, the handwritten character input frame setting information table 3-3 shown in FIG.
Since a match is found in step 12, the process proceeds to step S3-8,
The information of the frame size 3-6 and the pitch 3-7 between the frames is extracted, and the process proceeds to step S3-9.

In step S3-9, the above-described character input box size and number-of-frames information are stored in the pointer / variable buffer 2-14, and the changed contents of the document input settings are registered. Then, the flow returns to step S3-2. .

FIG. 26 shows a display example in which the size of the handwritten character input frame is automatically changed by changing the number of handwritten character input frames. As is clear when comparing FIG. 25 and FIG. 26,
It can be seen that the number of handwritten character input frames has been reduced from four to three, and the size of the handwritten character input frames has increased accordingly.

[0115]

According to the present invention described above, the number of character input frames can be freely selected when performing handwritten character input, so that the operator can input handwritten characters according to his / her preference and personality. Will be possible. Therefore, the usability of the document information processing apparatus can be improved, and the operation of inputting handwritten characters is facilitated, and the function thereof can be improved.

Further, according to the document information processing apparatus of the second aspect, when complicated character data such as kanji is input, the size of the character input box can be automatically increased. When the input of uncomplicated character data continues, the character input frame size can be automatically reduced.

As a result, when complex character data such as kanji characters are input by handwriting, a decrease in recognition accuracy due to a small character input frame can be prevented, the efficiency of document creation can be improved, and the character input The inconvenience that characters cannot be completely written can be solved.

In addition, when the input of less complicated character data continues, the character input frame size can be automatically returned to a smaller size, so that the character recognition accuracy can be improved.
In addition, the character input operation becomes easy.

According to the document information processing apparatus of the third aspect, when the input of less complicated character data such as alphanumeric characters is performed continuously, the number of character input frames can be automatically increased. When handwritten character input is performed one after another, handwritten character input and character recognition can be performed efficiently.

According to the document information processing apparatus of the fourth or fifth aspect, the number of frames (or character frame size) is automatically set in conjunction with the change of the character input frame size (or number of frames). Since it can be changed, the display area of the character input frame can be effectively used. As a result, the handwritten character input operation can be further facilitated, and the usability of the document information processing apparatus can be further improved.
