DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data output device for outputting a table including a plurality of areas.

[0002]

2. Description of the Related Art Conventionally, in a personal computer, an office computer, or the like, at the time of outputting a form, a table of a predetermined format set in advance is output, and corresponding item data is arranged and output in each item area constituting the table. ing. In this case, if there is no item data, the item area becomes a blank area.

[0003]

However, when there are many blank areas on a form, the entire form becomes difficult to see. Therefore, if you output diagonal lines in the blank area on the form,
It is considered that the blank area can be easily identified.
In this case, it is conceivable to set a start point at the upper left corner of the blank area, set an end point at the lower right corner of the blank area, and draw a diagonal line between the set start point and end point.
A blank area must be found from the table, and the start point and the end point must be set for each blank area, and the setting operation is extremely complicated.

An object of the present invention is to make it possible to immediately know where an actual data exists on a plurality of areas, and conversely where a blank area exists.

[0005]

The present invention provides a data output device for outputting a table including a plurality of areas.
It is characterized by comprising detecting means for detecting a blank area where no data exists in the plurality of areas, and output control means for identifying and outputting the area detected by the detecting means.

The operation of the means of the present invention is as follows.
When the detecting means detects a blank area where no data exists among the plurality of areas, the output control means identifies and outputs the area detected by the detecting means.

[0007] Therefore, it is possible to immediately know where the real data is located on the plurality of areas and where the blank area is located.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing a basic configuration of an office computer. The CPU 11 controls various operations of the office computer in accordance with a form creation program and a form output program stored in advance. Form data input from the keyboard 12 is taken into the CPU 11 and input processing is performed. The information is displayed on the text screen of the display unit 13 or transferred and stored in the file memory 14.

Further, the CPU 11 responds to a form output command from the keyboard 12 and expands the form data read from the file memory 14 into the page memory 16 in accordance with a table format set in the form format memory 15 in advance. At this time, the CPU 17 uses the work memory 18 to determine the drawing range of the oblique line data to be drawn on the form, and executes oblique line processing for outputting the oblique line data within the range.

Next, the contents of the form format memory 15 and the configuration of the work memory 18 will be described with reference to FIGS.

FIG. 2 shows an example of form creation. This form data has a four-record structure, and each record data is composed of four item data. The form format is divided into 4 × 4 = 16 item areas by vertical ruled lines and horizontal ruled lines. The row direction corresponds to record data, and the column direction corresponds to item data. In this case, as shown in FIG. 1, the form format memory 15 stores a starting point Y coordinate of the form (a Y coordinate corresponding to the upper left position of the form) and an update width of the starting point Y coordinate (a Y coordinate corresponding to one line size of the form). Width) is set. In the form format memory 15, Xa coordinates (X coordinates corresponding to the upper left position of the item area) and Xb coordinates (items) in the column direction of the form corresponding to the items I, II, III, and IV in the column direction of the form. (X coordinate corresponding to the upper right end position of the area) is set. Further, in the form format memory 15, a diagonal line type indicating a diagonal line at the upper right or a diagonal line ascending to the left is set as a diagonal line drawn in a blank area on the form. In FIG. 2, the symbol "x" added to the form indicates the form data, and the other indicates a blank portion where the form data does not exist.

The work memory 18 includes various parameters I ₁ , I ₁ ′ I ₂ , L ₁ , L ₁ ′, and L ₂ for determining the drawing range of the oblique line data to be drawn on the form, and the oblique lines in the determination range. In addition to storing the starting point coordinates (X ₁ , Y ₁ ) and the ending point coordinates (X ₂ , Y ₂ ) of the oblique line when drawing data, a diagonal line flag indicating whether or not to execute diagonal line processing to draw diagonal line data in the form Is stored. Here, parameters I ₁ , I ₁ ′ I ₂ in the work memory 18 are parameters for designating the item position in the column direction of the form, and parameters L ₁ , L ₁ ′, L ₂
Is a parameter for designating the line position of the form. As shown in FIG. 3, the rectangular area specified by the parameters I ₁ , I ₂ , L ₁ , and L ₂ is a hatched drawing range, and the parameter I ₁ is a rectangular area. left item position, parameter I ₂ is the rightmost item position of the rectangular area, further parameters L ₁ is the upper end row position of the rectangular area, parameters L ₂ represents a lower end row position of the rectangular area. The parameter I ₁ ′ is a work item position for obtaining the left end item position I _{1 and the} right end item position I ₂ , and the parameter L ₁ ′ is a work line position for obtaining the lower end line position L ₂ from the upper end line position L _1. Is shown.

Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG. The form data stored in the file memory 14 has a four-record configuration as shown in FIG. 2, and each record data is composed of four item data. It is assumed that corresponding format data is set.

When printing the form data stored in the file memory 14 based on the settings in the form format memory 15, the keyboard 1
The form output command is given from 2. Then, the CPU 1 returns to FIG.
The form output process is executed according to the flowchart of FIG.

First, at step S1, the starting point Y coordinate of the form is read from the form format memory 15, and then one record, first the first record data, is read from the file memory 14 (step S2). Each item data of the first record is arranged in the page memory 16. At this time, the starting point Y coordinate and the Xa coordinates set in the form format memory 15 corresponding to the items I, II, III, and IV, Each item data is arranged at the corresponding item position in the page memory 16 based on the Xb coordinates (step S3). Then, the starting point Y coordinate and each item I, I
Based on the Xa coordinates and Xb coordinates corresponding to I, III, and IV, the respective frame lines (horizontal rule lines, vertical rule lines) of the first line constituting the form are arranged in the page memory 16 (step S).
4).

Then, the process proceeds to step S5, and it is checked whether or not even one NULL item exists in the record. Here, the NULL item means a blank item in which no item data actually exists. Since all items in the first record shown in FIG. 2 are not NULL items, the process proceeds to step S7, where the file memory 14 is searched to determine whether there is a next record. Check whether or not.

Since the second record exists in the file memory 14, the process proceeds to step S8, where the Y coordinate is added by adding the update width in the form format memory 15 to the Y coordinate of the starting point, and then the step S2 is performed. Return to

As a result, each item data of the second record is arranged at a predetermined position in the page memory 16 and each frame line of the second line forming the form is arranged in the page memory 16 as described above. Is done. In this case, since the NULL item exists in the second record, the process proceeds to step S6, and the oblique line flag in the work memory 18 is set.

Then, the presence or absence of the next record is checked (step S7). Since the third record exists in the file memory 14, the process proceeds to step S8, where the Y coordinate is updated, and then the process returns to step S2.

Hereinafter, as a result of repeating the same processing one record at a time, all record data are arranged in the page memory 16 together with the frame lines.

When the absence of the next record is detected in step S7, the process proceeds to step S9, where the work memory 1
It is checked whether or not the oblique line flag is set in 8.
Here, the oblique line flag is set if at least one NULL item exists in the form, and the process proceeds to the oblique line process in FIG. 5. If the oblique line flag is not set, the process proceeds to step S.
10, the data in the page memory 16 is transferred to the printer 1
7 to print out.

On the other hand, when the process enters the oblique line processing, a record having a NULL item is searched from the file memory 14 (step S11), and it is checked whether or not a record having the NULL item exists in the file memory 14 (step S12). ).

Now, the second item of the second record is NU
Since the item is an LL item, the line position “2” is stored in the work memory 1
8 are set as the top line position L ₁ and the work line position L ₁ ′, and the item position “2” is set as the left end item position I ₁ and the work item position I ₁ ′ in the work memory 18 ( Step S13).

[0024] Then, the process proceeds to step S14, 'After updating the value by adding "1" to the value of the item position I _1' for work item position I ₁ item data corresponding to the file memory 14 Read (step S15), N
It is checked whether the item is a UL item (step S16). Now
Its value by an update of the work for the item position I ₁ 'is "3"
Therefore, the next item of the second record, that is, the third item data is read from the file memory 14. In this case, the item is also a NULL item, and since the NULL item is continuous, the process returns to step S14, and the work item position I ₁ ′ is updated again. As a result, the fourth item data is read from the file memory 14, and this item is
Since the NULL item is further continued with the NULL item, the process returns to step S14, and the value of the work item position I ₁ ′ is set to “5”.
Update to

When the NULL items continue in the column direction, the work item position I ₁ ′ is updated by the number of consecutive items from the left end item position I ₁ . Now
The value of the work item position I ₁ ′ is “5”, but since the fifth item does not exist, the absence of a NULL item is detected in step S16, and the process proceeds to step S17, where the value of the work item position I ₁ ′ "1" is subtracted from, and sets the right end item position I ₂ to the value in the work memory 18. In this case, the right end item position I ₂ is "4".

[0026] proceeds to the processing for determining the lower end row position L ₂ When this way to confirm the right end item position I ₂ based on the leftmost item position I1 (step S18~S25).

[0027] First, the leftmost item position and updates the value "1" is added to the work for the row position L ₁ 'in order to currently specified the left end item position I _1, which dropped one in the row direction than the line Let I ₁ be the work item position I ₁ '(step S1).
8). Since the value of the work line position L ₁ ′ and the value of the left end item position I ₁ are set to “2” in step S13, the work line position L ₁ ′ is set to “3” in step S18. The use item position I ₁ ′ becomes “2”, and the second item on the third line is designated. Then, item data specified by the work line position L ₁ ′ and the work item position I ₁ ′ is read from the file memory 14 (step S19), and it is checked whether or not the item is a NULL item (step S20). Now, the second item on the third line is N
Since the item is a UL item, it is checked whether or not the NULL item continues in the column direction while updating the value of the work item position I ₁ ′ (steps S21 to S23). Now, in the third line, since the third item is also a NULL item, the process proceeds to step S24 to check whether the work item position I ₁ ′ matches the right end item position I ₂ . Here, the work item position I ₁ ′ is “3”, the right end item position I ₂ is “4”,
Therefore, the inconsistency between the two is detected, the process returns to step S21, and the work item position I ₁ 'is updated again.
Since the second item is also a NULL item, the process proceeds to step S24. Here, the work item position I ₁ ′ coincides with the right end item position I _{2. If} this is detected in step S24, the process returns to step S18, and the same operation is repeated.

As a result, a line one line lower than the current line, that is, the fourth line is designated, and it is checked whether or not the second item of the fourth line is a NULL item (steps S18 to S18).
20).

Since the designated item is not a NULL item, the flow advances to step S25 to set the work line position L ₁ ′ as the lower end line position L ₂ . Thus, it determines the bottom line position L _2, the value is "4".

If the second item is also a NULL item in the fourth line, for example, it is checked whether the next item is also a NULL item (steps S21 to S2).
3), if the NULL entry is not continuous to the right item position I _2, for example, if the third and fourth items NULL entry, step from step S23 without updating the workpiece row position L ₁ ' Proceed to S25. Accordingly, the lower end row position L ₂ Also in this case is "4".

As a result, the rectangular area extending over the NULL items continuing in the column direction and the NULL items continuing in the row direction is represented by the leftmost item position I ₁ (2), the rightmost item position I ₂ (4),
It is specified by the top row position L ₁ (2) and the bottom row position L ₂ (4).

When the rectangular area is specified, the processing shifts to processing for drawing oblique line data within the area (steps S26 to S33).

First, the Y coordinate of the top row position L ₁ is determined, and this is set in the work memory 18 as the hatched starting point Y coordinate Y ₁ (step S 26). In this case, Y-coordinate of the upper end row position L ₁ is determined by the start point Y coordinate + (value × update width upper end row position L _1), which is the start point Y coordinate Y ₁ of the diagonal lines. The flow advances to step S27, the lower end row position L ₂ Y
Determined by the equation similar to the above coordinates, which is set as the end point Y coordinate Y ₂ of the diagonal line in the work memory 18.

Thereafter, the starting point X coordinate X ₁ and the ending point X coordinate X ₂ of the oblique line are obtained. In this case, the X coordinate X ₁ , X coordinate X ₁ , X The calculation method of ₂ is different.

That is, if the line type is the upper right, step S
As it is detected at 28, the program proceeds to step S29, reads the Xb coordinates of a specified item from the form format memory 15 specified by the rightmost item position I _2, which as a starting point X coordinate X ₁ of the diagonal line in the work memory 18 set. Next, the Xa coordinates of the designated item are read out from the form format memory 15 designated by the left end item position I ₁ , and are stored in the work memory 18 at the end point X coordinate X of the oblique line.
Set as ₂ (step S30).

On the other hand, when the line type is upwards to the left, the form format memory 15 specified by the leftmost item position I ₁
It reads Xa-coordinate of the designated item from, this is set as the starting point X coordinate X ₁ of the diagonal line in the work memory 18 (step S31). Then, X of the specified items from the form format memory 15 specified by the rightmost item position I ₂
It reads the b coordinate, which is set as the end point X coordinate X ₂ of the diagonal line in the work memory 18 (step S32).

When the X coordinates X ₁ and X ₂ have been obtained in this manner, the flow advances to step S33 to start the coordinates (X ₁ , Y ₁ ) of the oblique line.
Then, the end point coordinates (X ₂ , Y ₂ ) are connected to generate straight line data (diagonal line data), which is arranged in the page memory 16.

Then, returning to step S11, another NU is set.
If there is an LL item, the above operation is repeated below,
When the absence of the NULL item is detected in step S12, the process proceeds to step S10 in FIG. 5, and the data in the page memory 16 is printed out.
