Description

The present invention relates to a character processing device such as a word processor and an electronic typewriter.

[Prior Art] Conventionally, in a word processor, the following two methods are known for formatting the number of characters and the character pitch. That is, the first method is a method of directly performing the format setting by directly specifying the number of characters per line and the character pitch, and the second method is the method of setting the character pitch for the print area fixed by the type of paper. When specified, this is a method of performing formatting by automatically calculating the number of characters per line.

[Problems to be Solved by the Invention] However, in the case of the first format setting method, when printing is performed on a standard form sheet having a predetermined entry frame such as a contact note or a resume, it is necessary to fill in the form beforehand. Since it is necessary to measure the width of the frame and artificially calculate the character pitch based on the number of characters to be printed in this entry frame and set it, the format setting is extremely complicated and troublesome.

In the second format setting method, the number of characters is automatically determined by specifying the character pitch. A table is provided for storing the number of characters corresponding to all character pitches that can be specified according to the paper size. Because it is. Since this table is based on the print area fixed according to the paper size, this system cannot be applied to the above-described format setting for standard paper.
Therefore, it is necessary to provide tables corresponding to various print areas in order to be applicable to format setting for standard paper, but it is not necessary to provide tables corresponding to various print areas. Is too many to be practical.

An object of the present invention is to make it possible to arbitrarily select the size of the printing range, to automatically determine the number of characters in one line based on this selection, and to easily change it.

[Means for Solving the Problems] Means of the present invention are as follows.

Selecting means for arbitrarily selecting the size of the printing range in which characters are printed, and character number determining means for determining the maximum value of the number of characters per line based on the size of the printing range and the character size selected by this selecting means, First display control means for displaying the maximum value of the number of characters in one line determined by the number of characters determining means on the display screen, and the number of characters in one line within the range less than the maximum value of the number of characters in one line displayed by the display means. And a second display control for displaying the changed number of one-line characters on the display screen every time the number of characters is changed and set by the one-line-character number change setting unit. And a confirming means for confirming and registering the number of characters in one line displayed at the time of confirming operation.

[Operation] The operation of the means of the present invention is as follows.

When the operator arbitrarily selects the size of the print range in which characters are printed, the maximum value of the number of characters per line is determined based on the size of the selected print range and the character size. The maximum value is displayed on the display screen. The operator confirms the maximum number of characters per line displayed on the display screen, and can arbitrarily change and set the number of characters per line within the range below the maximum value of the number of characters per line, and each time this change setting is made , The number of characters per line set and changed is displayed on the display screen. When the operator performs a finalizing operation, the number of characters per line displayed at that time is finalized and registered at the time of the finalizing operation.

Therefore, within the range of the maximum value of the number of characters per line that is automatically determined based on the character size and the size of the print range selected arbitrarily, the operator can change the number of characters per line while observing the display. It is possible to repeat the above, and after the desired one-line character number is displayed by these change setting operations, the desired one-line character number can be confirmed after confirming it.

[Embodiment] Hereinafter, the present invention will be specifically described with reference to FIGS. 1 to 4. The present embodiment shows an example applied to a Japanese word processor.

Structure Figure 1 is a basic block circuit diagram of this Japanese word processor. Reference numeral 11 in the figure denotes an input section of the word processor. In addition to various character keys or the like normally provided on the keyboard of the input section 11, a format setting key KA and an execution key KB used for setting format information. , Release key KC,
Up / down / left / right cursor keys KD, KE, KF, KG, shift key KH
Is provided. Then, the input unit 11 has an input control unit.
When the key sampling signal from 12 is given and a key operation is performed in the input unit 11, the sampling signal is selected according to the operation key and sent to the input control unit 12 as a key input signal to be converted into a key code. After being converted
It is taken in by the CPU (central processing unit) 13.

The CPU 13 controls various operations according to a microprogram stored in advance, that is, input processing, kana-kanji conversion processing, format setting processing, etc., and the CPU 13 includes format information memory 14, sentence memory 15, counter section 16, Work RA
M17 and area counter 18 are bidirectionally connected.

The format information memory 14 and the text memory 15 are composed of a RAM (random access memory), and data write / read operations are controlled under the control of the CPU 13. Then, when setting a plurality of print areas corresponding to the print format of the standard size paper, the format information memory 14 shows XY indicating the start position (left end position) of each print area corresponding to each row address area.
Areas X ₀ and Y ₀ that store coordinate position data of the coordinate system,
It is configured to have an area C for storing the number of characters per line to be printed in the corresponding printing area and an area P for storing the printing pitch. Further, the text memory 15 stores text data to be printed in the print area specified by the coordinate position data set in the format information memory 14 in correspondence with each print area.

The counter unit 16 includes an X counter and a Y counter for counting the X coordinate component indicating the print head position with the movement of the print head described later.
It has a configuration including a Y counter that counts coordinate components.

The work RAM 17 is provided with an LX register for fetching the X coordinate data of the left end position of the designated print area, an LY register for fetching the Y coordinate data, and an RX register for fetching the X coordinate data corresponding to the right end position of the designated print area. In the work RAM 17, the A register that stores the maximum number of characters per line that can be printed in the specified print area calculated based on the contents of the LX register and the RX register, and the predetermined minimum number of characters per line 3 "to the a register that stores the number of characters selected within the maximum number of characters in the A register, and the print pitch in the specified print area that is calculated based on the contents of the LX register, RX register, and a register. A B register is provided. The contents of the LX register, LY register, a register, and B register are set in the designated row address area of the format information memory 14 under the control of the CPU 13. In this case, the area counter 18 is a counter for designating the row address of the format information memory 14, and this count value data is sent to the format information memory 14 as a write address under the control of the CPU 13.

On the other hand, the display unit 20 is connected to the CPU 13 via the display control unit 19, and the text data and the like output from the CPU 13 are displayed on the display control unit 1.
After being converted into a display drive signal in 9, it is sent to the display unit 20 and displayed. A printer 22 is connected to the CPU 13 via a print control unit 21, and the text data and the like output from the CPU 13 is printed on the recording paper set in the printer 22. The printer 22 is composed of a thermal printer having a print head PH composed of 24 thermal printing elements,
It is a character size of 24 x 24 dots and can print up to 50 digits per line.

Operation First, the standard paper, such as the contact form and resume, whose print format is defined, is set in the printer 22. When the format setting key KA is operated, the mode is set to the format setting mode and the operation according to the flow of FIG. 2 is started. First, the guidance of "position?" Is displayed on the display unit 20, and it is instructed that the coordinate position data of the left end of the print area should be input and set (step S1). Here, FIG. 4 shows the print format of the standard size paper, and the print area (shown with hatching in the figure) PA-1, PA-2, PA-3, PA-1 is the left end position, Print areas PA-1 to PA- in the figure
The leftmost position of 4 is It is represented by. In the present embodiment, the horizontal direction of the standard paper corresponds to the X coordinate axis, the vertical direction corresponds to the Y coordinate axis, and the upper left end of the standard paper corresponds to the XY coordinates “0, 0”. Then, when the guidance display as described above is performed, the input setting of the left end position of the print areas PA-1 to PA-4 is performed corresponding to the entry frame entered on the standard form sheet. In this case, the area setting is performed by operating the cursor keys KD to KG or the shift keys KH + cursor keys KD to KG (pressing the shift key and the cursor key at the same time). It is moved by the amount (step S2).

FIG. 3 is a flow chart showing the specific contents of the print head moving process. First, when entering this flow, a key sampling process (step S2-1) is performed, and then the presence or absence of a key input is checked (step S2-2). If there is no key input, the process returns to step S2-1 and the key input is performed. Until step S2-1 and step S2-2 are repeated, a key input waiting state is entered. Then. When any key is operated, is the operation key the execution key KB (step S2
-3), the release key KC (step S2-4), or the cursor keys KD to KG for moving the print head PH is checked. Now, when the release key KC is operated, this is detected in step S2-4 and the format setting mode is released, but when the cursor keys KD to KG for moving the print head are operated, step S2- Proceeding to step 6, the print head PH is moved by a predetermined unit amount in a predetermined direction corresponding to the operation key. That is, assuming that the up, down, left, and right cursor keys KD to KG are operated, the print control unit 21 is driven and the print head
The PH is moved in the up / down / left / right directions corresponding to the operation keys by the print size of one character “24 dots”. So for example
Set the print head PH at the position of XY coordinates "0, 0" to the start position (left end position) of the print area PA-1 in FIG. If you want to move to If the XY coordinate of is 96,48, the right cursor key
If you operate KG four times and the down cursor key KE twice, the print head PH will Is set to the position. Like this, the cursor keys KD to KG
Since the print head PH is moved in units of 24 dots by the operation of
As described above, the print head PH can be moved to a desired position, for example, by operating only the cursor keys KD to KG. It is only necessary to accurately set the position to, but if a deviation of 23 dots or less occurs, the shift key KH and the cursor keys KD to KG are simultaneously pressed to finely adjust the movement of the print head PH. The print head PH is
The cursor is moved up and down, left and right in 1 dot units instead of in 24 dot units, corresponding to the up, down, left, and right cursor keys KD to KG. Such print head movement processing (step S2-6)
After that, in the next step S2-7, the values of the X counter and the Y counter are updated according to the movement amount of the print head PH.
That is, if you operate only the cursor keys KD to KG, the X register,
"24" is subtracted from the value in the Y register, or the X register,
"24" is added to the value of the Y register. That is, "24" is subtracted from the value in the Y register by operating the up cursor key KD, and "24" is added to the value in the Y register by operating the down cursor key KE.
Is added. Also, by operating the left cursor key KF, "24" is subtracted from the value in the X register, and the right cursor key KG
By the operation of, "24" is added to the value of the X register. Similarly, "1" is added to or subtracted from the X register and Y register values by "1" as the print head PH is finely adjusted and moved by simultaneously pressing the shift key KH and the cursor keys KD to KG. To be done. Now, the print area PA in Fig. 4
Left edge position at -1 Assuming that the print head PH is set correctly on the
The register value is "96" and the Y register value is "48". When such counter update processing is completed, step
Return to S2-1. Then, after confirming that the print head PH is correctly set at the left end position of the print area to be set,
Next, operate the execution key KB. Then, this is detected in step S2-3, and the flow exits from the flow of FIG. 3 and proceeds to step S3 of FIG.

Then, in step S3 of FIG. 2, the X coordinate data set in the X counter is transferred to the LX register of the work RAM 17, and the Y coordinate data set in the Y counter is LY.
Transferred to register.

When the setting operation of the left end coordinate position data is completed as described above, the guidance "Right end?" Is displayed in step S4, and this time it is instructed that the right end coordinate position data of the print area should be input. According to this, the cursor key K
When F, KG, etc. are operated, a print head moving process (step S5) similar to step S2 described above is performed. In this case, it is not necessary to move the print head PH in both XY directions,
It is only necessary to move it from the left end position to the right in the X direction. In this way, the print head PH is moved to, for example, the print area PA-1 in FIG.
Right edge position When the execution key KB is operated after moving to
Proceeding to S6, the X coordinate data corresponding to the right end position set in the X counter is fetched in the RX register.

Then, in the next step S7, the maximum number of characters that can be printed from the left end position to the right end position of the print area to be set is calculated. This character number calculation program is performed according to the following equation.

INT [RX-LX / 24] INT: Function that obtains an integer value RX: X coordinate value of the RX register LX: X coordinate value of the LX register The maximum number of characters obtained in this way is A of work RAM17.
Register and a register are set. Then, the value of the a register is digitally displayed on the display unit 20 (step S8). When 2, the maximum number of characters is "0"
Can be printed in the print area when it is made into dots 1
Visually check this display with the maximum number of characters per line,
If the number of characters to be set is the maximum number of characters, execute key immediately
Operate the KB, but if it is less than the maximum number of characters, operate the down cursor key KB. Now, the CPU 13 checks the presence or absence of a key input in step S10 next in step S9 for key sampling processing.
As a result, if there is no key input, the process returns to step S9 and repeats the same processing, and is in a key input waiting state. Here, when the down cursor key KE is operated, this is detected in step S11, and the process proceeds to step S12 to check whether the value of the a register exceeds the predetermined minimum number of characters "3". Now, the maximum number of characters is set in the a register, and if this value is 4 or more, the value of the a register is decremented by 1 with the operation of the down cursor key KH and the value is displayed (step S13). , S14) and returns to step S9. Since the value of the a register is decremented by -1 each time the down cursor key KE is operated in this way, the value of the a register is subtracted by the number of times of operation, but when the value of the a register becomes "3", The operation of cursor KE becomes invalid and a
The register value remains "3". Then, the display
In 20, the desired number of characters is displayed because the number of characters within the range from the maximum number of characters that can be printed in the print area to the minimum number of characters “3” is displayed as selection candidates each time the down cursor key KE is operated. Continue to operate the down cursor key KE until. Here, in the case where a value smaller than the desired number of characters to be set is displayed by mistake, the up cursor key KD is operated. Then step S1
This is detected in step 5, and the flow advances to step S16 to determine whether the value of the a register is equal to the maximum number of characters in the A register. In this case, at the end of the maximum number of characters, the value of register a is incremented by 1 and the value is displayed (steps S17 and S18), and the process returns to step S9. If the value in the a register is equal to the maximum number of characters, the up cursor key KD
Is invalidated, and the value of the a register remains the maximum number of characters. Thus, every time the up cursor key KD is operated, the value of the number of times of operation is added to the value of the a register.

Then, when the desired number of characters to be set is displayed on the display unit 20, the execute key is operated next. Then, step S19
This is detected in step S20, and the character pitch is calculated in step S20. This character pitch calculation program is performed according to the following equation.

INT [RX-LX / a] INT: Function that obtains an integer value RX: The rightmost X coordinate value of the RX register LX: The leftmost X coordinate value of the LX register a: The number of characters in the register The print pitch obtained in this way is It is transferred to the B register. Then, the process proceeds to the next step S21, in which the left end X coordinate position data in the LX register, the left end Y coordinate position data in the LY register, the number of selected characters in the a register, and the character pitch in the B register are read, respectively, and format information is read. It is set in the memory 14. Formatting in this case is performed on the areas X ₀ , Y ₀ , C and P of the row address area of the format information memory 14 addressed by the value of the area counter 18. Then, in the next step S22, the value of the area counter 18 is updated, and then the process returns to step S1 to enable the same format setting for the next print area.

In this way, when the format settings are sequentially performed on the print areas PA-1, PA-2, ... In FIG. 4, the left end position of the print area PA-1 is set in the area corresponding to the first row address of the format information memory 14. X coordinate, Y coordinate, number of characters, and character pitch are set, and the left edge position of the print area PA-2 is set in the area corresponding to the next line address. X coordinate, Y coordinate, number of characters, and character pitch are set. Hereinafter, similarly, the format information corresponding to the print areas PA-3 and PA-4 is sequentially set in the format information memory 14.

Then, when the text data to be printed is input in the print area in which the format information is set as described above, the text data is written in the text memory 15 corresponding to the print area. Then, when printing the text data in the text memory 15 on the standard size paper, a print key (not shown) is operated. Then, the print head PH is located at the left end position of the first print area PA-1 in FIG. Then, the text data read from the text memory 15 is printed in the print area PA-1 based on the set format. Then, when printing on the first print area PA-1 ends, the left end position of the next print area PA-2 The print head PH is moved to, and printing based on the set format is performed on the print area PA-2. The same applies to the print areas PA-3 and PA-4.

In the above embodiment, the format information includes the number of characters per line,
Although the character pitch is set, the number of lines in the designated print area, the line pitch or the line spacing, or the column spacing may be set.

Further, in the above embodiment, the number of characters selected within the range of the predetermined minimum number of characters “3” from the maximum number of printable characters in the designated print area is sequentially displayed by operating the cursor key. It is also possible to simultaneously display all the numbers of characters as selection candidates and select them with the ten keys. Further, instead of directly displaying the number of characters in the range, the range may be designated and displayed.

Further, in the above embodiment, when setting the print area, only the width direction is set and the vertical (row) direction is not set. However, for example, the start position (upper left end) and end position (lower right end) of the print area are set. If the coordinate position is set, the horizontal (width) direction and the vertical direction can be set.

Furthermore, the present invention is not limited to word processors, and can be applied to electronic typewriters and the like.

[Effects of the Invention] According to the present invention, the operator automatically determines the display within the range of the maximum value of the number of characters per line that is automatically determined and displayed based on the size of the printing range and the character size that are arbitrarily selected. It is possible to repeatedly change and set the number of characters per line while observing, and to change the desired setting by these change setting operations.
Display the number of lines and confirm it, then select 1
You can check the number of lines.
