Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document preparation device such as a Japanese word processor having a pen input function, and more particularly to a document preparation device and a print control method capable of inputting a handwritten image and printing it together with a document.

[0002]

2. Description of the Related Art Heretofore, there have been some document preparation apparatuses which can input a document or the like using a dedicated pen in addition to a keyboard. In a document creating apparatus having such a pen input function, a tablet input section with transparent electrodes is integrally formed on the screen of the display section, and a pointing or writing operation is performed on this tablet with a dedicated pen called a stylus pen. By doing so, it is possible to specify an arbitrary position on the screen and input a handwritten document.

In the document creating apparatus having such a pen input function, a handwritten image can be drawn on the display screen, and the image can be printed on paper as required.

[0004]

By the way, when a handwritten image is printed together with a document, the document is usually set with a print pitch such as a digit pitch (character pitch) and a line pitch (line feed pitch). Printing is executed according to the pitch. However, if handwritten images are printed at this printing pitch, even if they are connected on the display screen, there is a problem in that there is a space in the row and column direction during printing, which makes the appearance very bad.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a document creation apparatus and a print control method capable of printing a handwritten image in good appearance and in high quality in accordance with the print pitch of the document. To aim.

[0006]

A document creating apparatus according to the present invention includes a document inputting means for inputting document data, an image inputting means for inputting handwritten image data, and the document inputting means. Display means for displaying the document data and the handwritten image data input by the image input means, and image management means for managing the handwritten image data displayed on the display means in units of line digits of the document data, Based on the management by the image management means, an image print control means is provided for enlarging and printing the handwritten image data for each line digit of the document data according to the print pitch of the document data.

[0007]

With the above arrangement, the handwritten image data input by the image input means is displayed on the display means together with the document data input by the document input means.
It is managed in units of line columns of document data. Therefore, it is possible to prevent the handwritten image data from being cut in the line digit direction by enlarging and printing the handwritten image data in line digit units of the document data according to the print pitch of the document data.

FIG. 4 is a diagram for explaining a method of printing handwritten image data. As shown in FIG.
It is assumed that document data (here, characters “A” and “B”) are displayed in 6 × 16 dots, and handwritten image data is displayed below the document data. When printing, the document data has a preset printing pitch of 24 × 24 dots (here, both the digit pitch and the line pitch are 32 dots)
Is printed with.

Here, if the handwritten image data is printed as it is, as shown in FIG. 3B, a gap is left in accordance with the printing pitch. Therefore, the present invention is characterized in that the handwritten image data is enlarged and printed for each line digit of the document data to connect the handwritten image data in the line digit direction as shown in FIG. In this case, if the magnification in the digit direction of the handwritten image data is Xi and the magnification in the row direction is Yi, it can be expressed by the following equation.

Xi = digit pitch / number of display dots in the digit direction (1) Yi = row pitch / number of display dots in the row direction (2) In the example of FIG. 4, according to the above equation (1), Xi = 32 / Since 16 = 2 Yi = 32/16 = 2, the handwritten image data is printed by being doubled in the row digit direction.

Next, the operation of the embodiment will be described. When printing is instructed through the keyboard 14, the CPU 11 causes the CPU 11 of FIG.
The print control process as shown in the flowchart of FIG. That is, as the initial setting, the row-direction pointer "LI
With NE set to "1" and the digit direction pointer "COLUM" set to "1" (steps S1 and S
2), the CPU 11 reads the character code of the first digit of the first line from the document buffer 12a of the RAM 12 (step S).
3). Then, the CPU 11 reads out a character pattern for printing (a character pattern of 24 × 24 dots) corresponding to the character code from the character pattern area 13b of the ROM 13 and develops this on the X coordinate of the print buffer 12c (step S4). .

Here, the CPU 11 searches the image buffer 12b to check whether or not handwritten image data exists at the same line digit position (step S).
6) If there is handwritten image data (step S
7) The same data is developed on the X coordinate of the print buffer 12c (step S8). In this case, by obtaining the enlargement ratio according to the printing pitch (digit pitch and line pitch) of the document data according to the above equations (1) and (2),
The handwritten image data is expanded and developed based on the expansion rate. The printing pitch (digit pitch and row pitch) is preset in a column pitch table and row pitch table (not shown) in the RAM 12.

In this way, the CPU 11 expands the print data for one line in the print buffer 12c while updating the digit direction pointer "COLUM" (step S9).
(S11), the printer 24 prints one line through the printer interface 25. Then CP
U11 feeds the paper by the line pitch, updates the line direction pointer "LINE", and repeats the same processing as above (steps S13 to S15).

As described above, the handwritten image data is managed on a line digit unit basis of the document data, and at the time of printing, it is enlarged for each line digit line of the document data according to the print pitch of the document data. As shown in, the handwritten image data can be printed by connecting them in the line column direction of the document data.

In the above embodiment, the handwriting image data is input by the pen input method. However, the present invention is not limited to the pen, and even when the handwriting image data is input using a pointing device such as a mouse. Can be applied by means similar to the above.
