Abstract

PURPOSE:To obtain beautiful printing of an array easy to be seen by a method wherein format information of a printing line space is established by giving ruled line position information read by an image scanner to a line space establishing means. CONSTITUTION:A data processor is a small sized character processor having an image processing function, to which a percentage judging part 22 and a line width control part 23 are added. A scanner 20 scans paper with ruled lines, and sends each one line of read data to the percentage judging part 22. When the percentage judging part 22 receives one line content of serial data, it outputs the information to a line width control part 23 by judging how percentage on-dot is included therein. The line width control part 23 establishes a line space by information inputted from the percentage judging part 22, and outputs it to a format information part 24 in which format information of a present editing document is stored. Therefore, by only scanning printing paper on which the ruled line or the like are printed, format information meeting the paper can be automatically established, and beautifully arranged printing easy to be seen is simply certainly obtained.

FIG. 2 is a flowchart showing the main processing flow during formatting in the printing device of the data processing apparatus of the present invention. In the drawings, #1 to #8 indicate steps.

In the block diagram shown in Fig. 1 above, when the formatting key assigned in advance as a function key is pressed on the keyboard 10, the flow shown in Fig. 2 starts, and the formatting screen is displayed in step #1. Ru.

FIG. 3 is a diagram showing an example of a display screen during format setting in the printing device of the data processing apparatus of the present invention.

As already mentioned, the display screen of FIG. 3 can be accessed by pressing the formatting key assigned to the keyboard 10, for example, the formatting key KY on the keyboard 10 of FIG. 7 shown earlier as a conventional example. is displayed on the screen of the CRT display unit 1.

3. In the display state shown in FIG. 3, use the cursor keys and numeric keys on the keyboard 10 to designate each item and select the desired item.

As shown in the format setting screen of FIG. 3, in the printing device of the data processing apparatus of the present invention, in the paper size item, on the format setting screen described above in connection with FIG. 8 as a conventional example, In addition to the paper size item, ``Scanner''
- is added. FIG. 3 shows a state in which "scanner" is selected when the execution key is input.

In the flow shown in FIG. 2, in step #2, it is checked whether "scanner" has been selected.

To select "scanner", press the "execute key" in the display state shown in FIG. 3.

If the "scanner" is not used, the flow advances to step #3, where format information is set in the format information section 24 by the same operation as in a conventional data processing device, and step #3 is performed.
Proceed to step 8 to return to the editing screen.

On the other hand, if it is determined in step #2 that "scanner" has been selected, the process advances to step #4.

FIG. 4 is a diagram showing an example of a screen when setting a scanner format in the printing device of the data processing apparatus of the present invention.

As shown in the display screen of FIG. 4, there are three options for the scanner format: "Manual Scanner", "Data Correction", and "End", and one is selected.

In the flowchart of FIG. 2, in step #4, it is determined whether "scanner manual operation", "data correction", or "end" is to be performed.

When the key "1" is pressed and "scanner manual" is selected, the process advances to step #5.

First, a sheet of paper with ruled lines to be printed is set in the scanner 20, and a start switch (not shown) is pressed to scan the printing sheet.

When the scanner 20 scans the paper and outputs data line by line, in step #6, the line information (line spacing information) is sent to the format information via the percentage determination unit 22 and line width management unit 23. 24.

From step #6, the flow returns to step #4 again.

Here, the processing of steps #5 and #6 in FIG. 2 will be explained in detail.

Figure 5 shows "scanner input" in the flow of Figure 2.
3 is a flowchart illustrating a detailed process flow when setting row information. In the drawings, tt11 to #21 indicate steps.

The flow in Figure 5 is step #5 of the flow in Figure 2.
This corresponds to Step #6, and by detecting the width of the ruled line part and the width of the white area between them (width of the print area) for one page of printing paper, the line number is used as line information. Corresponding line spacing information is set.

Line spacing as format information is usually defined as the white area between one character printed in a dot pattern and one character on the next line (the area from the print end position of the previous line character to the print start position of the next line character). ) is expressed as the number of dots arranged at the same interval as the dot pattern.

However, in the flow shown in FIG. 5, the line spacing as format information is converted into information before being converted into the number of dots, that is, the scanner 20 scans line by line,
The process of detecting the line spacing based on the number of lines is shown.

Therefore, the line spacing obtained by this flow will then be converted into the number of dots.

As mentioned above, when the scanner 20 scans a sheet of paper with ruled lines and sends the read data line by line to the percentage determination section 22, the flow shown in FIG. 5 starts.

First, in step #11, all variables are initialized, and in step #12, it is determined whether reading of the entire sheet has been completed. Here, i is the number of printed lines, n is a parameter indicating whether the ratio of the number of on-dots per line is greater than or equal to the default value, sr 1 pt for ruled lines, Oyy for white areas, W (0) (i) is the width of the white part (printable area),
W(t )(i ) indicates the width of the ruled line portion.

In step #13, regarding one line of reading information input from the scanner 20, depending on the ratio of on (black) dots, whether one line on the paper currently being read is a ruled line part or a white dot. part.

In this case, when the ratio of the number of on-dots in one line is greater than or equal to a preset value (default value), n=1, and when it is less than or equal to the preset value, n=O.

In step #14, it is determined whether the current line status is the same as the previous line status.

If the current line state is the same as the previous line state, proceed to step #15 and W[n](i )
``+1'' and return to step #12 again.

Repeating steps #12 to #15,
In step #1.4, if it is detected that the current line condition is different from the previous line condition, step #1.
Proceed to step 6.

In this step #16, it is determined whether n=0 or not. If n=0 (one line read this time is white), the process advances to step #17 and the number of print lines i is set to ''. +1”.

Then, in the next step #19, W(n)(i) is set to 1 (this step #19 is a process for adding one line of the white area read this time in step #13)
.

Then, from step #19, the process returns to step #12 again.

Thereafter, the processes of steps #12 to #15 are repeated until one line of the next ruled line portion is read.

When one line of the next ruled line part is read, step #1
In step #4, it is detected that the current line condition is different from the previous line condition, and the process advances to step #16.

In this case, since the current read line is n-1 (one line read this time is a ruled line), the process advances from step #16 to step #17.

In this step #17, it is determined whether the number of white lines read up to the previous time is enough to print one character.

This judgment is made because, for example, when using paper with two ruled lines in one set, the white area between the two ruled lines is treated as the ruled line part when setting the line spacing. It will be done.

If W[n](i) is the default value (1
If the line spacing is equal to or greater than a preset value (a value that provides a line spacing sufficient to print characters), the number of lines detected so far is taken as the number of lines indicating the width of the white area. The value of the number of lines indicating the width of this white area is marked.

This information is temporarily stored in the memory within the line width management unit 23 along with information on the line number of the character.

If it is determined in step #18 that W(nHi) is less than or equal to the predetermined value, the paper is considered to have one set of two ruled lines.

The flow advances from step #18 to #20, where the number of white lines that have been read so far (the number of lines that have been read previously and counted in step #15) and the number of lines that have been previously determined to be ruled lines are determined. The value obtained by adding the number of lines read and the currently read line (the first line of the second ruled line), ie, W(1)[i], is set.

From step #20, the process returns to step #12, and the processes of steps #12 to #15 are repeated until the next white area is detected.

In this case, when the next white line is read, it is detected in step #14 that the line is in a different state from the previous line.

Then, the number of lines in the ruled line portion that has been counted so far is similarly stored at a predetermined address in the memory within the line width management section 23.

Thereafter, similar processing is repeated, and when it is detected in step #12 that reading of all lines of the printing paper has been completed, the process moves to step #21.

In step #21, the line width management unit 23
The number of dots was converted from the line number of the print, information on the number of lines in the white area W(0)(i), and information on the number of lines in the ruled line area W(1)(i) stored in the internal memory. In preparation for creating format information, these data are set and the flow shown in FIG. 5 is completed.

As already mentioned, the line spacing as format information is expressed as a value obtained by converting the area from the print end position of a character on the previous line to the print start position of one character on the next line into the number of dots.

In the flow shown in Fig. 5, in addition to the information on the line number of printing, information on the number of lines in the white area W[0)[i) and information on the number of lines in the ruled line area 'W(1)[i] are detected. be done.

From the information on the number of lines in the white area W[0)(i) and the information on the number of lines in the ruled/lined area W(11(i)), calculate the line spacing as format information converted into the number of dots and dots. do.

In the line spacing calculation process, information on the number of white lines W(0)
After subtracting the value of the character width in the line direction of the single character font (the width of the character font in the line direction is a constant value such as 16 dots or 24 dots) from (i), calculate the number of lines in the ruled line part. Add information W(1)['i].

In this case, the line number information W[0)(i) and W[1](・i) is determined by the scanning density of the scanner. For example, if the scanning density is 4 lines/mm, If there is, the width of one line is 174 mm, so the width of one line is converted to the number of dots to calculate the line spacing.

Note that the ratio between the width of one line (n/Ifim) and the number of dots varies depending on the printer.

By performing such calculation processing, the line spacing value converted into the number of dots, that is, the line spacing as format information is obtained.

When the flow in FIG. 5 is completed, in the second flow in the figure, the process returns from step #6 to step #4.

In this step #4, as described above, a scanner format screen as shown in FIG. 4 is displayed, waiting for input of "scanner input", "data correction", and "end".

If the key "2" is input here, the process advances to step #7 and a data correction screen is displayed.

FIG. 6 is a diagram showing an example of a screen when data is corrected in the printing device of the data processing apparatus of the present invention.

The data correction screen includes "Left margin", "Top margin", "Horizontal dimension", "Vertical dimension", "
The items ``Number of horizontal characters'' and ``Number of vertical lines'' are preset standard values.

If you want to change the standard values for any of these items, just specify the item and enter the desired value manually.

At the bottom of FIG. 6, the items "line number" and "line spacing" are displayed.

These values are the values obtained by converting the data on the number of lines obtained through the flow shown in FIG. 5 into the number of dots.

The value of this "line spacing" can also be corrected by manually inputting a key in step #7.

In step #7, the data input by the scanner and the format information set to standard values are corrected, and the process returns to step #4.

If, in step #4, the key "3" is input to instruct the end, the process advances to step #8 and returns to the editing screen.

With the above processing, formatting is completed.

When printing, first check the format information on the print screen.

If it is not a scanner format, the line is fed by a predetermined amount every time one line is printed.

On the other hand, in the case of a scanner format, when one line is printed, the line is fed by the line interval corresponding to the line number.

As described above, just by loading printing paper with printed lines, etc. on the scanner and scanning it, format information suitable for the paper can be automatically set. You can easily and reliably obtain beautiful prints with easy-to-read layouts.

As described above in detail, the present invention includes a keyboard, an image scanner, a display device, a printing device,
In a conventional data processing device that is equipped with a system memory and a central processing unit that controls each of these parts and has a document creation function, the print line spacing is determined as a format based on information about the ruled line positions of the printing paper read by the image scanner. and a line spacing setting means for setting the line spacing, and when printing a created document, the image scanner reads the ruled line position of the printing paper, and the read ruled line position information is provided to the line spacing setting means to provide format information of the printed line spacing. I'm trying to set it up.

Effects Therefore, according to the printing device of the data processing device of the present invention, it is possible to accurately and easily set a format suitable for report paper with ruled lines, slips with irregularly spaced ruled lines, etc. become.

In other words, not only when the line spacing is constant, but also when using paper with uneven line spacing, the line spacing can be read for each line and its format information can be set, resulting in beautiful and easy-to-read printing. This excellent effect can be achieved.
