Next, a description will be given of a print processing control routine performed by the control device C of the word processor 1 with reference to the flowchart of FIG. 6B. For convenience of explanation, the main control executed when the power of the word processor 1 is turned on is described. The routine will be described with reference to the flowchart of FIG. In the drawing, Si (i = 1, 2, 3,...) Is each step.

When the power is turned on to the word processor 1, this control is started and initial settings are first executed (S1), and a menu for selecting a desired processing content is displayed on the display 65 (S2). This menu includes "Create Document",
The processing contents of "format setting", "printing" and "others" are included. Here, the block cursor is moved to document creation by operating the cursor up / down key 8 and the execution key 12
Is operated to start the document creation processing (S3 / S4). Then, an input process of writing the input document data to the text memory 41 via the line buffer 42 and an input process of writing the input ruled line data to the ruled line data memory 45 are executed. When the end key 13 is operated, the document creation process is performed. Ends (S5), and returns to S2 to display the menu. At this time, the document data in the text memory 41 is stored in the text memory.
The ruled line data stored in the ruled line data memory 45 is stored in the ruled line data memory 73 in association with the document data.

When the format setting process is selected by operating the cursor up / down key 8 and the execution key 12, this process is started (S3.
S6). Then, based on the displayed format setting table, input necessary setting values such as the number of print lines per page and the number of print characters per print line, and operate the end key 13 to terminate the format setting process (S7). ), The menu returns to S2. At this time, the number of print lines is stored in the set line number memory 75, and the number of print characters is stored in the set character number memory 76.

Next, when the printing process is selected by operating the cursor up / down key 8 and the execution key 12, this process is started (S3 · S
8), a list of document names of each document data stored in the text memory 71 is displayed on the display 65 (S9). When the block cursor is moved to a desired document name by operating the cursor up / down key 8 and the execution key 12 is operated (S10), the print processing control program in the ROM 18 is read out, and the program proceeds to S11 to execute the print processing. Control (FIG. 6 (b)) is started. When the printing process control is started, after the printing paper 14 is fed to the printing position from the stacker, the page counter is started.
“1” is stored in the PC and the line counter LC, respectively, and the print end flag PF and the ruled line flag KF are reset (S2
0 ・ S21). Next, in the selected document data in the text memory 71 and the ruled line data in the ruled line data memory 73, the head address of the print line specified by the page counter PC and the line counter LC is the text pointer TP and the ruled line data pointer.
The document data for one print line is read out by the text pointer TP based on the number of characters in the set character number memory 76, and is stored by the ruled line data pointer KP.
The ruled line data for the print line is read (S23). Next, EOT
When the code is read and the print data, that is, the document data and the ruled line data, end at this print line (S24 • YE
S), a print end flag is set (S25). If the ruled line data does not exist (S26: NO), after the document data is printed (S29), the determination result in S30 is YES, the printing paper 14 is discharged (S31), and the process returns to the main routine. .

On the other hand, if the print data is not finished and there is ruled line data (S24 / NO, S26 / YES), the ruled line flag KF is set and the document and the ruled line are printed (S27, S28). Then, since the print end flag is not set, the determination result in S30 is NO, and the process shifts to S32. When the line counter LC is not equal to the set line number N, that is, when the line being printed is not the last printed line of the page (S32 / NO), the line counter L
Line feed operation is performed by incrementing C by one (S3
3), S21 and subsequent steps are executed. If the print data is not completed and the document data does not exist in the current print line, the S2
At 8, only the ruled lines are printed. If the print data is not completed and the document data and the ruled line data do not exist in the current print line, the document is not printed in S29.

When only the document is printed on the last print line of the page (S3
(2.YES, S34.NO), the page counter PC is incremented by one and "1" is set in the row counter LC (S36), and the page is changed (S37), and the process proceeds to S21. If the horizontal ruled line mode setting switch 4 is switched to select the horizontal ruled line addition mode when the document and the ruled line are printed on the last print line of the page (YES in both S34 and S35),
The ruled line data printed on the last print line is read, the ruled line data of the vertical ruled line 22 is searched, and the presence / absence and position of the vertical ruled line 22 are stored in the search ruled line data memory 81 (S38). next,
When there are at least two vertical ruled lines 22 in the last print line based on the data in the search ruled line data memory 81 (S39: YES), the page counter PC is incremented by one and the line counter LC is set to "1". The head address of the print line indicated by the line counter LC is stored in the ruled line data pointer KP (S40). Similar to S38, the ruled line data of the first printed line of the next page is searched to determine whether or not the vertical ruled line 22 exists and the position. It is stored in the search ruled line data memory 81 (S41). Next, based on the data in the search ruled line data memory 81, if there are at least two vertical ruled lines 22 in the first print line and the vertical ruled line 22 in the last print line and the vertical ruled line 22 in the first print line are respectively continuous (YES in both S42 and S43), based on the data in the search ruled line data memory 81, the first vertical ruled line (leftmost vertical ruled line) 22 to the last vertical ruled line (one Vertical ruled line on the right side) Dotted horizontal ruled line over 22
23 is additionally printed (S44). Then, the page is processed and the next print paper 14 is fed to the print position (S45). Next, the print paper 141 is moved by one print line in the reverse paper feed direction, and the next print paper 141 is moved to the first print line of the next page. A dotted horizontal ruled line 23 is additionally printed at the upper end from the first vertical ruled line 22 to the last vertical ruled line 22, and the printing paper 14 is moved in the paper feed direction by one line (S46).
Move to 21.

On the other hand, if only horizontal ruled line data exists in the last print line of the page being printed in S39, the determination is NO and the process moves to S36. If the vertical ruled line data does not exist in the first print line of the next page in S42, or if the vertical ruled line data exists in S43 but is different from the vertical ruled line data in the last print line, the determination result is NO, and the process proceeds to S37. Therefore, in these cases, the horizontal ruled lines 23 are not additionally printed on the last print line and the first print line, respectively. For example, if the set number of rows N is 20
When the number of set characters is 19, the first page (the page being printed)
7A is stored in the ruled line data memory 73 as shown in FIG. 7A, and the ruled line data to be printed on the second page (next page) is stored as shown in FIG. 7B. When the ruled line data of the first page has three vertical ruled lines 22 on the 20th line corresponding to the last print line, the ruled line data of the second page has three vertical ruled lines 22 on the first line corresponding to the first print line. Since there are three vertical ruled lines 22 and these three vertical ruled lines 22 are all continuous, the lower end of the last print line of the first page during the printing shown in FIG. 7C and the lower part of FIG. In addition, dotted horizontal ruled lines 23 are additionally printed at the upper end of the first print line of the next page shown in (1) and from the first vertical ruled line 22 to the last vertical ruled line 22. Each ruled line data in the ruled line data memory 73 is shown corresponding to the printing position. In this case, in FIGS. 7A and 7B, the 0th column of the column corresponding to the print digit is an auxiliary memory for printing the vertical ruled line 22 at the left end of the first print digit of each print line. The zeroth line of the line corresponding to the print line is an auxiliary memory for printing the horizontal ruled line 23 at the upper end of the first print line of each print digit.

If another process is selected during the execution of the main control, that process is executed (S12), and the process returns to S2.

As described above, when the vertical ruled line 22 of the created table is continuous from the page being printed to the next page, the lower end of the last printed line of the page being printed and the upper end of the leading printed line of the next page are printed. Since the dotted horizontal ruled line 23 for dividing the table is additionally printed, each of the partial tables divided into the page being printed and the next page can be printed automatically and clearly.

In addition, since the horizontal ruled line 23 is automatically added when printing, an extra operation of inputting the horizontal ruled line 23 for separating in advance during tabulation can be omitted.

Note that the horizontal ruled lines 23 printed in S44 and S46 are not limited to dotted lines, and various horizontal ruled lines 23, such as alternate long and short dash lines, serving as table breaks may be printed.

The present invention can of course be applied to various word processors.

(Another embodiment)

By the way, as shown in FIG. 8 (a), the routine of the print processing control in the above embodiment is performed between S43 and S44.
When a table having an outer frame (surrounding ruled line) is created and the table is divided into two pages, a pair of vertical ruled lines 22 and these vertical ruled lines 22 , The upper end of which is in contact with the left and right ends of one horizontal ruled line 23, respectively, and the lower end of an upper partial table (hereinafter referred to as an upper closed side frame), a pair of vertical ruled lines 22 on the next page, and these vertical ruled lines The horizontal ruled lines 23 may be printed on the upper end of the lower partial table (hereinafter, referred to as a lower closed three-sided frame) in which the lower end of 22 is in contact with the left and right ends of one horizontal ruled line 23, respectively. . Except for this changed part, it is the same as the above-mentioned embodiment.

The print processing control routine according to the second embodiment will be described. When the determination in S43 is Yes, the page counter PC is decremented by one and the last print line "N" is set in the line counter LC (S50). Then, in the next S51, the search processing of the outer frame of the page being printed (FIG. 8B) is started. When this process is started, the row counter LC is decremented by one, and the presence / absence of vertical ruled line data and horizontal ruled line data is searched (S60 to S61). When the vertical ruled line 22 is present and the horizontal ruled line 23 is not present, (S62 / YES, S63 / NO), S60 to S63 are repeated to search for ruled line data for each print line toward the top print line direction, and when the vertical ruled line 22 is in contact with the horizontal ruled line 23 (S63 / YES) ), The first flag F1 is set (S64)
When the vertical ruled line 22 does not exist (S6

When the first flag F1 is set, that is, when the top-closed three-sided frame exists on the page being printed (S52 · YE
S), the page counter PC is incremented by one, and "1" is set in the line counter LC (S53), and in the next S54, the outer frame search processing of the next page (FIG. 8 (c)) is started. . When this process is started, the line counter LC is incremented by one, and the presence / absence of vertical ruled line data and horizontal ruled line data is searched (S70 to S71). When the vertical ruled line 22 is present and the horizontal ruled line 23 is not present (S72). (YES, S73, NO), S70 to S73 are repeated to search for ruled line data for each print line toward the final print line direction, and when the vertical ruled line 22 is in contact with the horizontal ruled line 23 (S73, YES) When the second flag F2 is set (S74) and control returns, and when the vertical ruled line 22 does not exist (S72 · N
O) The second flag F2 is set (S75), and the process returns to S55.

When the second flag F2 is set, that is, when the upper closed three side frame exists on the page being printed and the lower closed three side frame exists on the next page (S55: YES), S44 to S46 are executed. A dotted horizontal ruled line 23 is additionally printed from the first vertical ruled line 22 to the last vertical ruled line 22 at the lower end of the last print line of the page being printed and the upper end of the first print line of the next page. . For example, the first
When ruled line data to be printed on a page is stored in the ruled line data memory 73 as shown in FIG. 9A, and ruled line data to be printed on the second page is stored as shown in FIG. 9B, An upper closed three side frame exists on the first page, three vertical ruled lines 22 exist on the last print line, and a lower closed three side frame exists on the second page, and three vertical ruled lines 22 appear on the first print line. Exists, the lower end of the last print line of the page being printed as shown in FIG. 9C and the upper end of the first print line of the next page shown in FIG. The dotted horizontal ruled line 23 is additionally printed over the vertical ruled line 22.

When the upper closed three-sided frame and the lower closed three-sided frame are present on pages separated by a plurality of pages, the page counter PC and the page counter PC are set when the upper closed three-sided frame is printed during printing. The lower closed three-sided frame is searched in advance while incrementing, and when the lower closed three-sided frame is detected, a horizontal ruled line 23 is additionally printed at the lower end of the upper closed three-sided frame, and the lower closed three-sided frame is printed at the upper end of the lower closed three-sided frame. Dotted horizontal ruled lines at the first print line and the last print line of each page in the middle
23 may be additionally printed.

Also, for example, when a table created using three vertical ruled lines 22 and a pair of horizontal ruled lines 23 extending from the first vertical ruled line 22 to the second vertical ruled line is divided into a first page and a second page. Is the vertical ruled line
Whether or not 22 is in contact with the horizontal ruled line 23, that is, whether or not the upper closed three-sided frame and the lower closed three-sided frame exist, is searched in advance. As shown in FIG. 10, the lower end of the last print line of the first print paper
A dotted horizontal ruled line 23 extending from the first vertical ruled line 22 to the second vertical ruled line may be additionally printed at the upper end of the first print line of the printing paper 14b.

In any of these cases, each of the divided partial tables can be automatically and clearly printed.
