Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a document processing device such as a word processor equipped with a printing device, which has a function of automatically determining the printing layout when printing. Regarding the same device.

(b) Prior Art In document processing devices, the print layout has traditionally been automatically determined based on the number of characters per line, number of lines per page, and paper size specified by the operator. .

Conventionally, for each paper size, the length of the character spacing and left and right margins (left and right margins) corresponding to the number of characters on one line, and the line spacing and top and bottom margins (top and bottom margins) that correspond to the number of lines on one page. the length of
Fixed values were stored in a table in advance, and the fixed values were read out according to specifications. In other words, the character spacing and length of the left and right margins are determined based on the specified number of characters per line and paper size, and the line spacing and length of the top and bottom margins are determined independently based on the specified number of lines per page and paper size. It was something to do.

Therefore, in the print layout, the character spacing, line spacing, and the lengths of the left and right margins and the top and bottom margins are determined completely independently, and therefore,
This has the disadvantage that the print layout is not always optimal, such as the length of the top and bottom margins being extremely long compared to the length of the left and right margins, and the character spacing being wider than the line spacing. Ta.

(c) Purpose of the invention The present invention expands the scope of application to the specification of the number of lines on one page, the number of characters on one line, and the paper size, and always
The purpose is to automatically determine an ideal print layout that is visually orderly and makes effective use of paper.

It is composed of:

...a data memory consisting of a character spacing memory 11 storing CS ₃ and CS _X in order from address ADR0;
12 is a print layout control unit that determines the optimum line spacing, character spacing, left and right margin lengths, and top and bottom margin lengths based on the data stored in the specified data buffer 4, paper length memory 5, and data memory 6 ; 13 is a line spacing; Bushdown stack STACK1 for storing LS, top and bottom margin length VM, character spacing CS, and left and right margin length HM, respectively.
A stack memory consisting of STACK2, STACK3, and STACK4, 14 a printing device such as a dot printer, 15 reading the determined line spacing, character spacing, top and bottom margin lengths, and left and right margin lengths from the stack memory 13, and creating a print layout corresponding to these values. This is a print control unit that controls the printing device 14 to print the text read from the text storage memory 3.

Note that the text storage memory 3 has a memory area 3a that stores various data related to the input text, such as the number of lines per page LN, the number of characters per line CN, and the number of pages specified at the time of text input.

Therefore, in order to input a sentence, first, use the keyboard 1 to specify the number of lines per page LN and the number of characters per line CN, etc., and then input the sentence. 3, and data such as the number of lines LN and the number of characters CN are also stored in the memory area 3a. Then, in order to perform automatic printing, when the paper size PS is specified from the keyboard 1 and the automatic printing execution key is pressed, the print layout control section 12 stores the specified paper size PS in the buffer 4a, and
The number of lines LN and the number of characters CN are read from the memory area 3a and stored in buffers 4b and 4c, respectively.
Thereafter, the process shown in the flowchart of FIG. 2 is started.

That is, first, the address ADR0 of the line spacing memory 10 is
is specified, the minimum line spacing LS ₀ is read out, and based on the specified number of lines per page LN and the length per line (referred to as unit line length) D _L , the minimum effective vertical length required for printing is determined. Calculate m _V and compare this m _V with the paper portrait length PV of the specified paper size to determine the specified number of lines LN when the line spacing LS is ₀ .
Determine whether it fits on the paper. If it fits, the value obtained by subtracting the effective vertical length m _V from the paper vertical length PV (PV - m _V ) is determined as the upper and lower margin length VM, and it is determined whether this upper and lower margin length VM is within a predetermined range. judge. If it is within the specified range, the line spacing LS ₀ and the top and bottom margin length VM ₀ at this time are
They are stored in the stacks STACK1 and STACK2, respectively, and after being stored or when they are not within a predetermined range, the addressing of the line spacing memory 10 is incremented and the next line spacing _LS1 is read out. For the line spacing LS ₁ , the same processing as for LS ₀ is performed.
Then, after repeating the same process sequentially as LS ₂ , LS ₃ , and so on until the maximum line spacing LS _X is reached, the process moves to the next step. However, when the effective vertical length m _V becomes greater than the paper vertical length PV, the process immediately moves to the next step.

In this way, line spacing LS and top and bottom margin length
Each candidate data of VM is stack STACK1.
and stored in STACK2. In this case, line spacing
Since LS data is stored in order from shortest to shortest,
The longest line spacing is stored at address 0. still,
Before data is stored at address 0 of each bushdown stack in the stack memory 13,
An END mark is written in advance, so that when data is stored, the address next to the address of the first stored data is
It is assumed that the END mark has been written.

For example, assume that candidate data is stored as shown in FIG. 3A through the above-described processing.

In the next step, first, stack STACK1
By determining whether or not there is an END mark at address 0, it is determined whether candidate data has been obtained through the above processing. If candidate data is obtained as shown in Figure 3 A, character spacing CS and left and right margin length
Start processing to obtain HM candidate data. That is, specify address 0 of the character spacing memory 11, read the minimum character spacing CS ₀ , and print based on the specified number of characters in one line CN and the length per character (referred to as unit character length) D _C. Calculate _the minimum effective horizontal _length m _H required for
Determine whether CN fits on the paper. and,
If it does not fit, move on to the next step, but if it does, read out the character spacing stored at address 0 of STACK1, that is, LS ₂ , and find out that the ratio LS ₂ /CS _{0 to the character spacing CS 0 is} within the specified range. Determine whether it is within the range. If it is within the specified range, the value obtained by subtracting the effective horizontal length m _H from the paper horizontal length PH (PH - m _H )
is defined as the left and right margin length HM, and the character spacing CS ₀ and left and right margin length HM ₀ at this time are stored in stacks STACK3 and STACK4, respectively. After storage or when the ratio is not within the predetermined range, the addressing of the character spacing memory 11 is incremented, the next character spacing CS ₁ is read out, and the same processing is performed.
Then, after repeating the same process sequentially as CS ₂ , CS ₃ , and so on until the maximum character spacing CS _X is reached, the process moves to the next step.

In this way, the candidate data LS ₂ with two line spacings,
First, regarding LS ₂ of LS ₁ , candidate data for character spacing CS and left and right margin length HM are stored in stacks STACK3 and STACK4, respectively. At this time, since the storage order is in ascending order of character spacing, the longest character spacing is stored at address 0.

Here, it is assumed that candidate data is stored through the above-described processing, for example, as shown in FIG. 3A.

In the next step, by determining whether or not there is an END mark at address 0 of stack STACK3, it is determined whether candidate data has been obtained through the above processing, and the data obtained as shown in Figure 3 A is determined. In this case, read the top and bottom margin lengths and left and right margin lengths stored at address 0 of stacks STACK2 and STACK4, that is, VM ₂ and HM ₄ , and check whether the ratio of these margin lengths VM ₂ /HM ₄ is within a predetermined range. Determine whether or not. If it is not within the predetermined range, the character spacing _CS4 corresponding to the left and right margin length _HM4 at this time is released from the stacks STACK4 and STACK3, respectively. Then, as shown in Figure 3B, the stacks STACK3 and STACK4
At address 0, candidate data CS ₃ having a shorter character interval than CS ₄ and candidate data HM ₃ having a longer left and right margin length than HM ₄ are stored, respectively. Therefore, using this left and right margin length HM ₃ ,
It is determined again whether the margin length ratio VM ₂ /HM ₃ is within the predetermined range, and if it is within the predetermined range, it is assumed that the optimum print layout has been obtained, and the process is terminated.

Therefore, as a result, the optimum values of the line spacing, top and bottom margin lengths, character spacing, and left and right margin lengths are stored at address 0 of each pushdown stack in the stack memory 13. For this reason,
When a termination signal is input from the print layout control section 12 to the print control section 15, the print control section 15 reads each of the determined optimum values from the stack memory 13, and prints in the print layout corresponding to these optimum values. This is executed by the printing device 14.

By the way, line spacing LS ₂ and top and bottom margin length VM ₂
Regarding character spacing CS ₄ as candidate data,
CS ₃ , OS ₂ and left and right margin length HM ₄ , HM ₃ ,
Even if all HM ₂ is read, the margin length ratio
If there is no suitable VM/HM, the line spacing LS ₂ and the upper and lower margin length VM ₂ at this time are released from the stack memories 1 and STACK 2 of the stack memory 13, and the process returns to the flowchart in FIG. 2 to set the next line spacing. Regarding LS ₁ and upper and lower margin length VM ₁ ,
Select candidate data for character spacing CS and left and right margin length HM. Then, the new candidate data is stored in the stacks STACK3 and STACK4, as shown in FIG. 3C. Below, as above, the margin length ratio
Determine VM/HM and determine each optimal value.

As described above, in the process of the print layout control unit 12, the optimal values for line spacing, character spacing, top and bottom margin lengths, and left and right margin lengths are selected and the print layout is automatically determined. Exceptionally, appropriate character spacing and left and right margin lengths may not be obtained for the line spacing and top and bottom margin lengths as the last candidate data. Therefore, in this embodiment, such a case is handled by setting the character spacing to the minimum character spacing CS ₀ and using the corresponding left and right margin length HM ₀ as the left and right margin length. In addition, if no candidate data for the line spacing and top and bottom margin lengths is obtained, in this embodiment, the minimum line spacing LS ₀ and the corresponding top and bottom margin lengths VM ₀ are used as the line spacing and top and bottom margin lengths, respectively. By using this, the print layout is determined.

In this embodiment, after selecting candidate data for line spacing and top and bottom margin lengths, candidate data for character spacing and left and right margin lengths was selected. After that, candidate data for the line spacing and top and bottom margin lengths may be selected. In this case, the maximum and minimum values of the left and right margin lengths are memorized and it is determined whether the left and right margin lengths are within a predetermined range. If such a determination is made, it is not necessary to determine whether the upper and lower margin lengths are within a predetermined range.

In addition, all line spacing and character spacing candidate data,
It is not necessarily necessary to store them in the memory as in this embodiment, but for example, the minimum value and maximum value may be stored, and within that range, the minimum value is used as the initial value and sequentially added at predetermined intervals. Candidate data may also be obtained.

By the way, the top and bottom margin length and the left and right margin length indicate the addition length of the top margin length and bottom margin length, and the addition length of the left margin length and right margin length, respectively, but once the paper size is determined, the top margin length By determining only one of the and bottom margin length,
The other is determined by itself, and the same applies to the left margin length and right margin length. Therefore, in this embodiment, the top and bottom margin lengths and the left and right margin lengths are determined, but it is also possible to decide only one of the top and bottom margin lengths and one of the left and right margin lengths. , exactly the same effect can be obtained.

(f) Effects of the Invention The present invention includes a first determination means for determining that the ratio between the line spacing and the character spacing is within a predetermined range, and a first determination means for determining that the ratio between the top and bottom margin lengths and the left and right margin lengths is within a predetermined range. Since it has a second determination means for determining,
Line spacing, character spacing, top and bottom margin lengths, and left and right margin lengths can be determined in relation to each other,
Therefore, in specifying the number of lines on one page, the number of characters on one line, and the paper size, it is possible to widen the range of applications in which an optimal print layout that is visually uniform and makes effective use of paper can be realized.
