Abstract

PURPOSE:To enable line printing of an arbitrary document containing second- level characters and external characters to be performed and enable a normal operation to be secured for a long time with a battery as a power source, by effectively utilizing a floppy disk drive and replacing floppy disks at most two times according to a displayed prompting message for inserting an exclusive floppy disk, in the execution of printing. CONSTITUTION:When executing printing, it is discriminated whether a character code to be pattern-developed is the one for an external character or the one for a second-level character. When the character code to be expanded is an external character code, a prompting message for loading a floppy disk for storing external characters is displayed. When the character code to be expanded is a second-level character code, a prompting message for loading a floppy disk for storing second-level characters is displayed. After the loading of an exclusive floppy disk according to the displayed prompting message is confirmed, a floppy disk drive is started to control the access to the floppy disk loaded therein.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a print control method for a document creation device, and in particular,
The present invention relates to a print control method for a text creation device that has a battery-powered floppy disk drive for storage and effectively uses the floppy disk drive during printing to greatly expand the number of printable second-level characters and external characters.

(Prior Art) In recent years, document creation devices have been using LCDs (liquid crystal displays) as display mechanisms and CMT as document file mechanisms.
A small, lightweight, and low-cost document creation device called a so-called personal word processor using a cassette-type magnetic tape device has now been realized. In this type of personal word processor, batteries are used to further improve mobility and operability. 1! A device that can be driven by a source is required;
In addition, from the viewpoint of functionality, expansion of the document storage area, expansion of printable characters, etc. are required.

Therefore, in order to significantly expand the document storage area, a 3.5-inch mini-floppy disk drive capable of high-speed random access, for example, is provided as external storage, and this floppy disk drive can be effectively used during printing to provide a second-level A device configuration has been devised in which a character pattern to be printed is obtained from a floppy disk when printing out characters.

However, this type of personal word processor has difficulty in operability for the operator during printing. Additionally, when printing, a situation arises in which the floppy disk drive and printer are simultaneously driven by the same battery power source, which places a very heavy load on the battery power source, which significantly shortens the battery life. A problem arises in that it is impossible to ensure normal operation for a long period of time.

(Problems to be Solved by the Invention) As mentioned above, in conventional battery-powered personal word processors, the number of characters such as second-level characters that can be printed is greatly limited, and the number of characters that can be printed is greatly limited. If an attempt is made to effectively use this method to generate character patterns such as second-level characters, there are problems in that it is difficult for the operator to operate the system, and normal operation cannot be ensured for a long time.

In a personal word processor equipped with a floppy disk drive used for document storage, the present invention makes effective use of the floppy disk drive and allows relatively simple replacement of the floppy disk up to two times per display guide when printing. The present invention provides a printing control system that can perform line printing of arbitrary second-level characters and branches including external characters in a simple operation, and can ensure normal operation over a long period of time using an N battery power supply.

[Structure of the Invention] (Means for Solving the Problems) The present invention determines whether a character code to be pattern developed during printing is a character code of a non-standard character or a character code of a second level character. and guide display means for instructing loading of a floppy disk for storing custom characters when determining a custom character code, and guide display means for instructing loading of a floppy disk for storing second-level characters when determining a second level character code, and following the above-mentioned display. The configuration is such that the loading of a dedicated floppy disk is confirmed and access to the floppy disk is controlled.

(For production) When printing, it is determined whether the character code to be developed in the pattern is a non-standard character code or a second-level character code, and if it is a non-standard character code, it is stored in 7O for storing non-standard characters.
A guide message instructing loading of a 2-level disk is displayed and output, and if it is a second level character code, a guide message instructing loading of a floppy disk for storing second level characters is displayed and output. After confirming the fI of the dedicated floppy disk according to the display of this guide message, the floppy disk 7 and the disk drive are started, and access to the loaded floppy disk is controlled. As a result, in a personal word processor equipped with a floppy disk drive used for document storage, the floppy disk drive can be used effectively when printing, and the floppy disk can be replaced up to two times in accordance with the display guide, making it relatively easy. It is possible to perform line printing of documents including arbitrary second-level characters and external characters, and to ensure normal operation over a long period of time using battery power. .

Each guide message is shown.

Here, the operation of one embodiment will be explained with reference to the above figures.

When inputting a sentence containing kanji, the key input signal from the keyboard 30 is sent to the CPU 11 in the 5110.
The data is converted into kana-kanji under the control of , and stored in the document buffer 141 in the RAM 14. At this time, the CPU 11 outputs a scan signal to the keyboard 30 via the PP 112 and the decoder 13, and sends the return signal to the P
Input P112 to perform key discrimination and generate a key code. Furthermore, the kana-kanji conversion dictionary in the ROM 15 and the provisional dictionary in the RAM 14 are indexed for the designated part of the kana-kanji input based on the same key code.
After performing the kana-kanji conversion process, the input character code string including the converted kanji code is stored in the document buffer 141.

During the above-mentioned text input, the input characters stored in the text buffer 1141 are sequentially developed into patterns on the line image buffer 140 under the control of the CP Ull.
D! The signal is displayed on the LCD 50 by the display control of the ti control circuit 17 and the display drive of the LCD driver 51.

Up to 4 sentences are displayed on the LCD 50 according to the row/column specification using the cursor keys.
It can be displayed arbitrarily with a character arrangement of 0 digits x 4 lines, and is used for proofreading and correction of wording.

For example, if you want to specify character decoration or stop printing on a line basis for the above input document, select and display the character string at the line position you want to decorate using the cursor keys,
Line modification is specified by operating the [line modification fliI] key in combination with the [n function] key and another specific key. The detailed row tX decoration means in this case is disclosed in Japanese Patent Application No. 60-129237.
(buffet preparation device), so its explanation will be omitted here.

Next, the printing processing operation of the above-mentioned document will be explained.

When printing this document, text printing is specified by operating the [document print] key in combination with the [function] key and another specific key. Here, it is assumed that full-text printing is specified by a combination operation of the [Enter] key and the [¥] primary key.

When the CPU 11 determines that the [document print] key has been operated, the CPU 11 switches the display mode of the LCD 50 from the document display mode to the print menu display mode.

When the CPU 11 determines the operation input of the [Document Print] key, it initializes the count value of the line counter indicating the print line position, and then controls the LCD control circuit 17 to display the LCD 50 as shown in FIG. The first line above displays the sentence in the first line of the designated intersecting circle, and the second line on the L CD 50
Print menus are sequentially and selectively displayed on and after the cursor key operation. At this time, item selection is performed by operating the cursor keys in the left and right directions, and screen switching is performed by operating the [Select/Execute] key.
On the initial screen when specifying full-text printing shown in a), move the cursor to the "Standard" position and press the [Select/Execute] key to select "Standard" printing, and
The display screen on the CD 50 switches from the screen shown in FIG. 9(a) to the screen shown in FIG. 9(b-1). After selecting each item in Figure 9 (b-1) and Figure 9 (b-2) by operating the cursor keys in the same way as above, by operating the [Select/Execute] key, you can enter the print menu setting mode. The mode shifts to the print execution processing mode, and the print processing is executed. Also, on the initial screen when specifying full-text printing shown in Figure 9(a) above, "
By moving the cursor to the position of ``Vertical/horizontal conversion'' and operating the [31 Select/Execute] key, ``vertical/horizontal conversion'' printing is selected, and the display screen on the LCD 50 changes from the screen in Figure 9(a). The screen changes to the screen shown in FIG.

In this case as well, after selecting each item, click [Select/Execute]
By operating the key, the mode shifts from the print menu setting mode to the print execution mode, and the print process is executed.

In addition, during the setting period of the print menu above, the LCD
As shown in FIG. 9, the sentence in the first line of the specified document is continuously displayed on the first line of 50, and the display continues even during subsequent printing.

The display screen during printing is shown in FIG.

In addition, even in the case of partial printing or single line printing, the first line on the LCD 50 will display the information shown in Figures 13 and 13 from the time the screen changes depending on the print mode specification until the end of printing. 14
As shown in the figure and FIG. 11, the sentence in the first line of the specified document is continuously displayed. Further, the above-mentioned "standard" printing and "vertical/horizontal conversion" printing differ in the control including motor excitation on/off of the serial printer 60, the details of which will be described later with reference to FIG. 6. Also, when executing the above printing, if there are second level characters or non-standard characters in one line of text to be printed, you will be prompted to insert a special floppy disk as shown in Figure 15, but the ID message will not be displayed.
This is displayed on the D50, and its display operation will also be described later.

After setting the print menu, the specified document stored in the document buffer 141 in the RAM 14 is read out line by line, and after the pattern is displayed on the line buffer (LB), the serial printer 60 prints the specified document. Printed out. At this time, in one line of character string to be printed, the external character and the second
When standard characters are mixed, pattern development for one line is performed twice: first, normal characters and non-standard characters are developed, and then second-level characters are developed.

The character pattern conversion process at this time will be explained with reference to FIGS. 4 and 5.

CP tJ 11 first stores document buffer 1 in RAM 14.
After setting the first line address of the print designated document stored in 41 in the character code pointer and setting the second level character flag and the twice expansion flag to "0", character expansion processing is executed (see Fig. 4). Steps A1 to A3).

In this character development process (step A3 in FIG. 4), character code discrimination processing for second-level characters and non-standard characters is performed, which will be explained with reference to the flowchart shown in FIG.

In the character development process described above, the CPU 11 first checks whether the development flag is "0" twice, and then checks if the development flag is "0".
If so, it recognizes that this is the first expansion process on the same line and outputs a carriage return command to the serial printer 60 via the printer controller 18 (steps 81 and 82 in FIG. 5).

Then, read the character code from the document buffer 141 according to the address in the document buffer 141 indicated by the character code pointer, save it in the character code save area, set the character type flag to "0", and load the character code from the character code save area. First, it is determined whether or not the character code is a code of 85 wards or more assigned to the registration of external characters (steps 83 to BB in FIG. 5).

Here, if the code is 85 wards or higher, set the character type flag to "1" to indicate that it is a non-standard character code, and if it is 85 wards or lower, it will be assigned to the next level 2 character. If the code is within the 48th to 83rd wards, the character type flag is set to ``2'', indicating that it is a second-level character code. set (steps 86 to B9 in FIG. 5).

In addition, codes for 85 wards and above (external characters), 48 wards to 83 wards (
If the code is not one of the codes (second-level characters), then it is determined whether the content of the double expansion flag is rOJ, and then it is determined whether the content of the character type flag is "2". (Steps 810 to 812 in FIG. 5). Here, the content of the twice expansion flag is "
"0", indicating that the content of the character type flag is a first-level character other than the second-level character code or a custom character code.
Or, if it is "1" and the content of the character type flag is "0", the character pattern data corresponding to the above character code is read from the kanji pattern memory unit (KPM) and the same pattern data is passed through the character pattern buffer. and writes to the line buffer (LB) according to the address indicated by the write pointer (step B28. sii in FIG. 5, 814.
B15°B25).

In this way, if the content of the twice expansion flag is "0" indicating that it is the first expansion process, and the character return flag is the first expansion process,
When rOJ indicates a standard character, the character pattern according to the character code read from the document buffer 141 is sequentially displayed on the line buffer (LB).

Also, when the content of the twice expansion flag is "O" indicating that it is the first expansion process, and the content of the character type flag is "2" indicating that it is a second level character code, the second level Set the flag to "-1", update the write pointer, reduce the number of unprinted characters in the line to be printed by one character, and if the number of characters is not "0", that is, the number of unprinted characters in the print line If remains, update the character code pointer by 2 bytes (one character code), read the character code from the document buffer 141 according to the address indicated by the character code pointer, and save it in the character code save area in the same way as above. , repeatedly executes character type discrimination and pattern expansion processing for the same character code (steps 310 and 811 in Fig. 5, B1
．． 3.826-829,83-).

In this way, during the first pattern processing on the same line, if a second-level character exists in that line, the second
Skips level character expansion processing and begins character pattern expansion processing for the next character digit.

Also, when the content of the twice expansion flag is "0" indicating that this is the first expansion process, and the content of the character type flag is "1" indicating that it is a non-standard character code, the serial printer 6
The motor excitation of the same printer is canceled at the end of the operation of 0 (
(the motor is turned off), a message prompting the user to insert a floppy disk with external characters is read from the ROM 15, and the message is sent to the LCD driver 51 via the LCD fE, II tin circuit 11 and displayed on the LCD 50 (
FIG. 5 Steps 814-B18°B20).

Examples of the message prompting the user to insert the external character floppy disk are shown in FIGS. 15(C) and 15(d). Here, FIG. 15(C) shows each message when the external character floppy disk is not inserted, and FIG. 15(d) shows each message when another floppy disk is inserted.

When it is confirmed that the external character floppy disk has been loaded into the floppy disk drive 70 according to the message prompting the user to insert the external character floppy disk, the external character pattern data according to the above character code is read from the loaded external character floppy disk, and the same data is read out from the loaded external character floppy disk. After reading and writing the character pattern data to the character pattern buffer, confirm that the mode is not a specific print mode (for example, custom character-ratio printing), turn off the motor of the floppy disk drive 70, and write the custom character pattern data written to the character pattern buffer. Read out,
Line buffer (LB) according to the write pointer address
) (steps 821 to B25 in FIG. 5).

Furthermore, after that, the self-contained pointer is updated and the number of unprinted characters in the line to be printed is decreased by one character, so that the number of characters becomes "0".
If not, that is, if unprinted characters on the print line remain,
2 bytes of character and code pointer (1 character code)
After updating, the character code is read out from the document buffer 141 according to the address indicated by the character code pointer and saved in the character code save area, and the character type determination and pattern development process for the same character code is repeatedly executed (fifth step). Figure steps 826-829, 83-).

In this way, when the content of the twice-expansion flag is rOJ, which indicates the first expansion process, if the character code to be output is a code other than the second-level character,
Each character pattern of a custom character or a first level character according to the character code is sequentially expanded into a pattern on a line buffer (LB).

The above-mentioned process is executed repeatedly in sequence, and the number of unprinted characters in one line in the first character expansion process on the same line disappears, that is, the number of unprinted character digits becomes "0". When this is confirmed (step B28 in Figure 5), the first character development process on the same line (step A3 in Figure 4) is performed.
).

Next, the content of the second level character flag is determined, and if the content of the flag is not rOJ, the content of the second level character flag is set to "0", and the content of the exhibition flag is set to "0" twice. ”
After setting , the second character expansion process on the same line begins (steps A4 to A6 in FIG. 4).

Here, the content of the twice-opened flag is not "0", and
Check that the content of the character type flag is "2" (
Steps 810 and 812 in Fig. 5), wait for the end of the operation of the serial printer 60, cancel the motor excitation of the printer (motor off), and read a message from the ROM 15 prompting the insertion of the second level floppy disk. , the same message is sent to the LCD driver 51 via the LCD lilti11 circuit 17 and displayed on the LCD 50 (steps 814 to B19 in FIG. 5).

Examples of the message display prompting the insertion of the second level floppy disk are shown in FIGS. 15(a) and 15(b). Here, FIG. 15(a) shows each message when the second level floppy disk is not inserted, and FIG. 15(b) shows each message when another floppy disk is inserted.

When it is confirmed that the second level floppy disk has been loaded into the floppy disk drive 70 according to the message prompting the insertion of the second level floppy disk, the loaded second level floppy disk will be inserted. After reading the second level character pattern data according to the above character code and writing the same data to the character pattern buffer, confirm that it is not in a specific print mode (for example, printing a list of external characters), and then turn off the motor of the floppy disk drive 70. Then, read out the external character pattern data written to the character pattern buffer and write it to the line buffer (LB) according to the address of the write pointer (Step 8 in Figure 5).
21-B25).

Furthermore, after that, the write pointer is updated, the number of unprinted characters in the line to be printed is divided by one character, and the number of characters becomes "0".
If not, that is, if unprinted characters on the print line remain,
After updating the character code pointer by 2 bytes (for 1 character code), read the character code from the document buffer 141 according to the address indicated by the character code pointer, save it in the character code save area, and then read the character code of the same character code. Character type discrimination and pattern development processing are repeatedly executed (steps 826 to B29.83 in FIG. 5).

In this way, when the content of the twice expansion flag is "-1" indicating the second expansion process, only when the character code to be output is a second level character, that character Each character pattern of the second level character according to the code is sequentially developed into a pattern at a corresponding digit position on the line buffer (LB).

The above process is repeated in sequence, and the number of unexpanded characters in one line in the second character expansion process on the same line has disappeared, that is, the number of unprinted character digits has become "0". When this is confirmed (step 828 in FIG. 5), the second character expansion process on the same line (step A6 in FIG. 4) is performed.
).

When each character development process described above is completed, the motor excitation of the serial printer 60 is canceled (motor off) after the operation of the serial printer 60 is completed, and a print execution command is then output to the printer 60 (step A7 in FIG. 4). A8
).

Next, the printing processing operation of the character pattern developed in the line buffer (LB) will be explained with reference to the processing flows shown in FIGS. 6 to 8. Here, when "standard" printing is specified and when "ta aspect conversion printing is specified,
Printer control is different as shown in FIG. Also, when printing is executed, under the control of the printer controller 18,
As shown in FIG. 7, the execution determination of triple punching and its divided printing control are selectively performed. Furthermore, when executing printing, after the print menu is set until the printing is completed, the character string of the print start line is displayed on the LCD 50 as shown in FIG. 8 (see FIGS. 9 and 9). 11 to 14), and when a print stop line is set, the character string in the next line is displayed when printing is stopped (as shown in FIG. 10).

First, with reference to FIG. 6, each printer control will be explained when "4M standard" printing is specified and when "vertical/horizontal conversion" printing is specified.

When executing printing, the CPU 11 determines whether the printing is in the "standard" printing mode or the "vertical/horizontal conversion" printing mode (step CI in FIG. 6).

Here, when determining "standard" printing, the pattern development start position on the line buffer (LB>) is determined from the first character digit position of the line to be printed, and then the position in Figure 3 corresponding to the line to be printed is determined. Load the line modification information shown below, and check whether it takes a long time to expand the character based on its contents (character size (enlargement/reduction), presence or absence of 0 selection, etc.) (full-width character (size 1)
If it is determined that it will take a long time, it outputs a carriage return command to the serial printer 60 via the printer controller 18, and further outputs a motor excitation off command ( FIG. 6 Steps 02 to C5).

As a result, the serial printer 60 enters the motor excitation off state after the carriage returns.

If it is determined that a long time is not required, only the carriage return command is output to the serial printer 60 via the printer controller 18 (step C4 in FIG. 6).
, C6). At this time, even after the carriage returns, the motor is not energized and turned off, so that printing can be performed immediately.

After that, the character pattern for one line is stored in the line buffer (LB) by the character expansion process shown in FIGS. 4 and 5 mentioned above.
Above m In! and outputs a print execution command to the serial printer 60 via the printer controller 18 (
Steps C7 and C8 in FIG. 6).

The serial printer 60 receives the print execution command and prints one line of character patterns developed on the line buffer (SHIB) (step C9 in FIG. 6).

When printing of one line is completed, a line feed command is output to the serial printer 60 via the printer controller 18, and then a check is made to determine whether the printing process of the sentence to be printed has been completed, that is, whether there are any unprinted lines. If there are any unprinted lines, the above-described line printing process is repeated again, and if there are no unprinted lines, the standard printing process is ended (steps C10, C11, C2 in FIG. 6). ~C9).

In this way, standard printing processing is executed.

Also, when determining whether to print with "vertical/horizontal conversion", first set the line feed value to "0", output a line feed command to the serial printer 60 via the printer controller 518, and then
Output the motor excitation off command (Step C in Figure 6)
21, C22).

As a result, in the serial printer 60, the motor is turned off after the line feed process is executed.

After this motor excitation is turned off, it is confirmed that the characters to be printed exist, and the character pattern for one line is transferred to the line buffer (L
B) Expand on top (Step C23,024 in Figure 6).

After determining the print start position from the character pattern developed on the line buffer p (LB), a carriage return command is output to the serial printer 60 via the printer controller 18, and then a print execution command is output. (Steps C25 to C27 in Figure 6).

The serial printer 60 receives the print execution command and prints the pattern developed on the line buffer (LB) (step 028 in FIG. 6).

When printing of one line is completed, the line feed value for the next printout is set, and the above-mentioned ``vertical/horizontal conversion printing process is repeatedly executed until there are no unprinted characters (steps C29, C22 to C28 in Figure 6). .

In this way, printer control including motor excitation control 0 is executed by different processing controls in the "standard" print mode and the "vertical/horizontal conversion" print mode.

Note that detailed pattern development processing and the like of the "rsu horizontal conversion" printing at this time are disclosed in Japanese Patent Application No. 60-247571, so a detailed explanation thereof will be omitted here.

Next, with reference to FIG. 7, a description will be given of the determination of execution of three strokes during printing and the division printing control thereof. Note that here, CPtJll has a model determination board, and the same model determination board displays whether the self model is a built-in floppy disk drive or a separate type. In this case, the inner R type model has a built-in NiCd battery with a large storage capacity, and the one-separation type model has a built-in normal dry cell battery with a small storage capacity compared to the NiCd battery.

When the printer controller 18 receives a print execution command from the CPU 11, it first sets the triple-strike flag to rOJ.
After setting the CPU 11, read the data on the CPU 11 model determination board that has been set in advance, and determine whether the model is a built-in NiCd battery type (with a built-in floppy disk drive) or a built-in dry battery type (with a built-in floppy disk drive). If it is a NiCd battery built-in type, it outputs a print execution command to the serial printer 60 and prints the line buffer (LB).
1r1 the pattern developed above! Normal print processing control is executed (steps D1 to D4 in FIG. 7).

In addition, if the type has built-in dry batteries, the line buffer (L
B) Set the start address as the dot check address in a predetermined register R1, set the initial 1 shift "0" as the number of dots to be counted in register R2, and set the number of check bytes as M44J (check unit: 2).
4X 48 dots> in register R3, and set r8J (1 byte) as the number of check bits in register R.
4 (steps D5 to D8 in FIG. 7).

Then, based on the dot check address stored in register R1, 1 byte of dot data on the line buffer (LB) is read into a predetermined shift register and shifted to the left one bit at a time to determine carry-on. The contents of register R2 are updated every time an on-dot is detected, and the processing is repeated by the number of check bytes, that is, 144.
Return bytes II (steps D8 to D15 in FIG. 7).

Then, check byte 1 (
When the dot-on determination for 144 bytes) is completed, the number of dot-on stored in register R2 becomes r576J or more (
1/2 or more), and determine whether the number of dots is r
If it is 576J or more, set a 3-time flag, that is, set the 3-time flag to "-1", and then output a print execution command to the serial printer 60 (steps D16, D17, and D4 in FIG. 7). .

After the printer controller 18 completes the above-described three-stroke discrimination process, the printer controller 18 selects the line buffer ('L B
) is sent to the serial printer 60, but at this time, if the triple-strike flag is set, the pattern data IIJfl placed on the line buffer (LB) is thinned out by a predetermined number (here, the line buffer (LB) 124 dots of 8 dots each are taken out in 3 steps.) The 124 dots of 8 dots each are divided into 3 parts by the process of 3 times, and printing of one line is completed in 3 printing operations.

Next, the display operation under the print mode will be explained with reference to FIGS. 8 to 14. When printing, as shown in Figure 8, after the print menu is set,
Until the printing is finished, Figures 9 and 11~
As illustrated in Fig. 14, the character string of the print start line is displayed on the LCD 50, and when the print stop line is set, when printing is stopped, the character string as illustrated in Fig. 10 is displayed. The next line of string is displayed.

It should be noted that the detailed setting means and stop control means for stopping printing at this time are disclosed in Japanese Patent Application No. 129229/1982, so a detailed explanation thereof will be omitted here.

When the CPU 11 determines the operation input of the above-mentioned [Document Print] key, it initializes the count value of the line counter indicating the print line position, and then controls the LCD II11 control circuit 17.
As shown in FIG. 9, the first line of the specified document is displayed on the first line of the L CD 50,
Print menus are sequentially and selectively displayed on the second and subsequent lines of the CD 50 according to cursor key operations (step 31 in Figure 8).
0-512). Item selection by left/right cursor key operations, screen switching by [select/execute] key operations, etc. at this time have been described above, so their explanations will be omitted here. Figure 9(a) is an example of the display when full text printing is specified, and Figure 9(t)-1) and (b-2) are examples of the display when full text printing is specified.
) is an example of the display when the item rl Jff1 is selected after "Standard" printing is selected, and (C) is an example of the display when the item is selected after "Landscape conversion" printing is selected in (a) of the same figure. are shown respectively.

Next, the CP Ll 11 sequentially reads the line modification information in the line attribute buffer 142 corresponding to the document to be printed, starting with the line modification information of the first line, and searches for the line position where "print stop" is set. After calculating the number of lines to be printed, a print execution command is output, and the printing process is executed up to that line position (steps 813 to 521 in FIG. 8).

During this printing, as shown in FIG. 11 on the LCD 50, a print start line and a printing form B (a message indicating that printing is in progress) are displayed. Note that when printing is stopped during "vertical/horizontal conversion" printing, the display format is as shown in FIG. 10.

When printing stops at the line position where "Print Stop" is set, the next line of text and the print menu are displayed, as shown in Figure 10 (a-1), and the menu can be selected using the cursor and the [Select/
By selecting the [Execute] key, the print menu shown in FIG. 4(a-2) is displayed.

Here, by operating the [SELECT/EXECUTE] key again, from the line position next to the above-mentioned stop line, that is, L CD 5
Printing according to the newly set document format starts from the line text displayed on the first line above 0.

Also, if it is detected that the text to be printed has ended (there is no document on line L+1) before the above-mentioned "stop printing" setting line is searched, the number of lines to be printed up to that line position is calculated,
Execute the printing process up to the accompanying position (Step S in Figure 7)
13-815. S22-524).

In this way, in print mode, the first line of the document to be printed is displayed when setting the print menu and during printing, and the next line of text is displayed when printing is stopped. The content of the printed document can be confirmed by being displayed.

As mentioned above, when printing, following the guide message that prompts you to insert the floppy disk displayed on the LCD 50, you can insert any second-level characters and external characters by replacing the floppy disk up to two times. In this case, the serial printer 6
Since the floppy disk drive 70 and the floppy disk drive 70 are not driven at the same time, normal operation can be ensured over a long period of time using the same internal power source.

[Effects of the Invention] As described in detail above, according to the present invention, according to the printing system of a document production device equipped with a floppy disk drive driven by a battery power source, characters to be developed in a pattern at the time of printing can be printed. If the code is a character code of a foreign character or not, the second
A means for determining whether the character code is a standard character, an instruction to load a floppy disk for storing a standard character when determining a standard character code, and an instruction to load a floppy disk for storing a second level character when determining a second level character code. According to the present invention, a personal word processor equipped with a floppy disk drive used for document storage is provided with a guide display means for controlling the loading of a dedicated floppy disk according to the above display, and controlling access to the floppy disk. When printing, the floppy disk drive can be used effectively to print any second-level character using a relatively simple task of replacing the floppy disk up to two times with the display guide prompting the insertion of a special floppy disk. , and documents including external characters can be printed in rows, and normal operation can be ensured over a long period of time using battery power.
