Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document processing method in an electronic device having a document processing function for processing document information.

In conventional document processing methods for electronic devices with document processing functions, when saving an input document in a storage unit, by specifying the name of the document, the document is associated with that name and saved in the storage unit. be done.

However, this saving process is performed unconditionally immediately after the name is specified. Therefore, if a user mistakenly specifies the same name as a saved document that should be kept as is when saving a document, the saved document that should be kept as is will be saved against the user's intention. I had a problem with it being deleted.

An object of the present invention is to provide a document processing method that can solve these problems.

Embodiments of the present invention will be described below with reference to the drawings. First, the basic configuration of an electronic device that employs the document processing method of the present invention will be explained based on FIG. Reference numeral 1 denotes a platen knob, which is used when manually loading paper or finely adjusting the printing position in the vertical direction. When the knob 1 is pushed inward, it is disconnected from the internal drive pulse motor, allowing manual rotation of the knob 1. The paper support 2 is a guide plate for paper, and is used to ensure that the printed side faces the operator even when thin paper is used. The page end indicator 3 is an indicator that indicates the length of the paper to the end line, and the operator adjusts the indicator 3 vertically as shown by the arrow in advance according to the vertical length of the paper, and then places the indicator 3 in the vertical direction to match the vertical length of the paper. When the top side of the paper that comes out reaches the scale position of the indicator 3, the length to the end line of the paper can be known. The release lever 4 is used to release a pinch roller located at the bottom of the platen from the platen and manually correct the inclination of the paper. The soundproof cover 5 is provided to suppress the impact sound of impact printing, and is made of transparent acrylic, so that the printed characters can be seen through the soundproof cover 5. When changing the typeface or replacing the ribbon cassette, open the upper cover 6 by rotating it backwards and replace the type wheel loaded in the carriage section or the ribbon cassette. This electronic typewriter has four types of horizontal printing pitch: 10, 12, and 15 characters per inch, and proportional spacing (hereinafter referred to as PS), where the printing pitch changes depending on the size of the type. . The scale 8 has three graduations marked with 10-character pitch, 12-character pitch, and 15-character pitch, and the carriage indicator 12 has three graduations with 10-character pitch, 12-character pitch, and 15-character pitch.
It is composed of lamps such as LEDs, and is mounted on the carriage and lights up the lamp corresponding to the pitch specified from the keyboard 10 to indicate the carriage position on the scale 8.

The keyboard 10 includes a character key group 10a for inputting and printing characters, and a control key group 10 arranged on both sides of the character key group 10a.
The input key signals are read in the keyboard control unit and sent to the main control unit including the MPU. If the input key is a key to be printed, related data is sent from the main control unit to the printer control unit. If the key is to be displayed, the data is sent from the main control unit to the control unit of the display 94 and displayed on the display 94. In the case of a key input that changes the illumination of a lamp on the keyboard 10, such as a print pitch change, a line feed pitch change, or an illuminated key, data for controlling the lighting of the lamp is sent from the main control unit to the keyboard control unit. .

According to this embodiment, functions that cannot be achieved with conventional typewriters can be achieved. The functions obtained by this embodiment will be introduced below, and its usefulness will be demonstrated by describing its key operation procedure. It should be noted that even common keys found in conventional typewriters can achieve a unique function when used in combination with the keys according to this embodiment. First, the functions and operating procedures of each key will be described, and then a control method centered on specific keys will be described to satisfy each function. This makes the electronic typewriter according to this embodiment even clearer. FIG. 2 is a front view of the operation panel of the electronic typewriter of this embodiment. In the figure, the PITCH key specifies the number of characters to be printed per inch, as described above. Every time you press the PITCH key
The display section L1, which is made up of lamps such as LEDs related to PITCH, displays 10, 12, 15, and PS in the order of
Moreover, it lights up cyclically. 10,12,1
5 is the number of characters/inch, but in PS, the number of characters per inch varies depending on the characters to be printed. LINE
The SPACE key indicates the line feed amount, and the basic unit length 1 of the feed amount is 1/6 inch. As before, the lamp L2 is lit cyclically by pressing the key. KB SELECT key is uppercase,

Select "§" and then use the SHIFT key to select one. Further, when the KB lamp is lit, the vertical line character "1" is selected. Each time the KB SELECT key is pressed, one of the lamps lights up.

The RM CONTROL key in the upper right corner controls the electronic typewriter's functions in the right margin. Either JUST, AUTO, or OFF is RM
It is selected each time the CONTROL key is pressed. This is also indicated by the lighting of lamp L4. When the JUST lamp is lit, select the right alignment function, and when the AUTO lamp is lit, perform auto line feed.
OFF literally does not indicate anything. OP.
The CONTROL key is used to determine the print mode of an electronic typewriter. As before, each time a key is pressed, one of C, W, L, and STORE lights up to indicate the print mode. C prints each character, W prints each word, L prints each line,
STORE means registration in internal storage,
When STORE, the mode is L for printing every line.

SSW1 on the left edge is related to the decimal tab function and is related to the 3-digit scale. In other words, SSW1
When specifying SP, a 3-digit scale is used with a space, and when specifying ``,'', a 3-digit scale is used with a ``,''. If "XX" is specified, 3-digit scale is not performed. SSW2 indicates the type of character.
The DECTAB key is used to specify decimal tabs, etc. The LAYOUT key has a lamp and is used to specify column layout, etc. The INDENT key also has a lamp and is used to specify automatic indent mode, etc. The FORMAT key also has a lamp. When related to page format, the MEMORY key also has a lamp, and when related to memory,
The MARREL key is used when operating beyond the left and right margins, the NONPRT key is used when referring to text memory, the REPEAT key is used when printing or inputting the same character continuously, and the key or key is used to move the cursor position on the display 94. , the BACK SPACE key on the right edge moves the print position toward the left margin, the <× key erases characters, the INDEX key advances the print paper one line, and the REVINDEX key moves the print position toward the left margin. When performing one line feed in the reverse direction, the CODE key has a lamp and can be used in conjunction with other keys to issue special instructions.
The CENT key is equipped with a lamp and is used to instruct centering printing, while the ☆ key is used to instruct to stop printing, etc.
The LM key sets the left margin, the RM key sets the right margin, the SET key sets the tab stop,
The CLR key is used to erase tab stops, the RELOC key is used to move the carriage to the final print location, etc. The left SHIFT key is used in conjunction with other keys to enter lowercase letters or to specify special functions.
The LOCK key above it is used to lock the SHIFT key. The BACK/TRACE key is used to go back to the previous line and correct printing.

The character key CK is inside the dotted line. The SPACE key is executed every time the carriage is pressed to the right to set a blank digit. The RETURN key returns the carriage to the left margin and feeds one line of printing paper. As shown in the figure, the RETURN key and SPACE key are included in the character key CK.

FIG. 3 shows its control block diagram. 44 is a microprocessor MPU,
The key signals from the keyboard 10 are interpreted according to the control sequences stored in the read-only memory ROM 53, and the printing mechanism 41, the display 94 or the text memory 54, the speaker 42, etc. are controlled. 45 is an address decoder, which receives control AB from MPU 44 and outputs SELROM,
SELBF, SELREG, SELM2, SELFF, SELM
1. Generate SELKEY, SELPRT, SELDSP, and SELBZ signals, respectively, ROM 53, row buffer 52, register group 51, auxiliary memory 57, flag group 50, text memory 54, keyboard control unit 24, printer control unit 16, display The control unit 9L and alarm control section 49 are designated and controlled. Note that addresses are assigned to the keyboard display, printing mechanism, memory, ROM, etc. for MPU processing.

Reference numeral 50 denotes a flag group, which stores the designated state of the typewriter, various modes, etc. A group of registers 51 is used to store intermediate results of processing operations. Reference numeral 52 is a line buffer for storing information regarding characters that have already been printed, and storing information to be printed during word-by-word or line-by-line printing operations. MPU4
4, when making corrections, the character that has already been printed is known by searching this line buffer 52 in the reverse direction, and the carriage is controlled to automatically reach the final print position of the line that has already been printed. do. 54
is a character string or text memory, which is a character example, text, information, etc. that the operator has registered according to the appropriate procedure.
Tab group information, etc. is stored with a title or without a title as the case may be. Sentence memory 5
4 is backed up by the battery 23, so even if the power switch is turned off, the information in the text message 54 will not be lost. The battery 23 is monitored by a power sensor 56 and a battery monitoring unit 55' as long as the power switch is turned on, and a warning is given to the operator when the voltage drops due to battery life or the like. 57
The auxiliary memory is backed up by 23 batteries like the text memory 54, and stores various operating modes immediately before the power switch is turned off.

The keyboard control unit 24 generates key information via a matrix 88 having lattice points corresponding to each input key, and also generates key information via a cathode driver 64 for displaying lamps or pitch indicators of illuminated key switches on the keyboard 10, operating mode, etc. It also controls the lighting of the lamp 89. The printer control unit 16 controls the printing mechanism 41 via the MD to perform printing. A display control unit 9L of the display section 9 controls information displayed on the display 94. The alarm control unit 49 generates an alarm sound through 42 speakers according to instructions from the MPU 44. 13 is a power supply unit as mentioned above;
Supplies power to each part.

Each unit, memory, register group, flag group, etc. is connected to the MPU 44 via a data bus DB, receives control from the MPU 44, and sends various data to the MPU 44, where predetermined arithmetic control is performed.

FIG. 4 shows the internal structure of the flag group 50.
The role of each flag is as follows.

KB2 is set when the KB SELECT key is pressed (KB2=1). Therefore, when KB2=1, K in FIG. 2 becomes effective as a character key for the vertical line character "1". KB
2 is cleared when I is selected using the KB SELECT key. INDENT sets INDENT=1 when automatic indent mode is started. When moving the carriage back toward the left margin,
It is always monitored, and when INDENT=1, it operates with the temporary left margin as the left margin. INDENT is cleared when automatic indent mode is canceled. When STORE is selected using the OP.CONTROL key, STR is set to 1, and when a selection other than STORE is selected, STR is set to 0. TR is set to 1 when the title name is entered using a character string reference operation and the RETURN key is pressed, and TR becomes 0 when the character string reference is canceled. NP is
When the NONPRT key is pressed, set NP to 1,
When the reference to the character string is released, NP becomes 0. SC indicates that a search character string has been input, such as by character string reference. Therefore, when the reference character string is input, SC=1, and when the reference to the character string, etc. is released, SC=0. The CMV becomes 1 when the centering mode (any of the 4 types) is established, and becomes 0 at the same time as the centering is released. TCNT = 1 when centering between tabs is specified
, MCNT becomes 1 when centering between margins is specified, PCNT becomes 1 when centering between specified positions is specified, and WCNT becomes 1 when centering between words is specified.

FIG. 5 shows the internal structure of the register group 51. Register PRTEPT indicates the final point of characters stored in row buffer 52. register
PRTEPT indicates the printing end point within the characters stored in the line buffer 52. register
CRGPT indicates the position of the carriage from the left margin of the printing paper, and the distance traveled by the carriage from the left margin is stored. For register DCRGPT, the carriage does not move immediately when a character key is input during word-by-word printing, line-by-line printing, etc. Therefore, it is necessary to know and monitor the temporary carriage position.
At this time, DCRGPT is used to store the actual quantity to be moved. PITCH stores information about each print pitch when the PITCH key is pressed to specify the character size, that is, the print pitch. MPU4
4, refer to PITCH when knowing the print pitch. Like PITCH, LNSP stores the current paper feed amount, that is, the operating state of the LINE SPACE key.
RMC is the RMCONTROL key, OPCNT is the OP.
Remember the state of the CONTROL key. LM, RM are
It stores the positions of the left margin and right margin at that point in the same unit as CRGPT, etc. SSW1 and SSW2 store the states of SSW1 and SSW2 on the operation panel, respectively. DLM is a save register for the left margin LM when in automatic indent mode.

TAB1 to TABn store the position of the tab stop at that time and have the same dimensions as LM, etc.
WORK is temporary storage of information during control or processing.
Used for saving information, etc. CPT refers to a certain point on the line buffer 52, corresponds to the character where the carriage is located, and is used when making corrections. That is, for each character printed, the status of the printed character type, printing pitch, etc. at that time is memorized, and when correction is necessary, this is stored in order from the oldest character digit to the youngest character digit, like a first-in-first-out stack.
The MPU 44 decodes the characters in the order in which they are taken in and reversely reproduces the past carriage movement state and printing paper feeding state, thereby making it possible for the carriage to reach the final character position of the line printed in the past.

LC stores the number of lines of printing paper fed.

FIG. 6 shows the internal structure of the row buffer 52. The unit memories of the row buffer 52 are numbered from 0 to n. The character type, print pitch, and print type can be stored at the address of each unit storage area. This information will be used for corrections and other purposes. The character type at address I is printed character information taken in from the keyboard control unit 24 in FIG. 3, that is, character key information. Also, the slide switch at the time of this key input (SSW2 in Figure 2)
The state (SSW2 in the register group 51) corresponds to the type of address printing. Also, Figure 2
The state of PITCH is also in PITCH in the register group 51, and this is stored at the address as a print pitch. The length of the line buffer 52 is greater than the maximum number of characters to be printed per unit line, and is so long that it can store, for example, 300 characters for two lines. BACK
When the TRACE key is pressed and the carriage is moved backwards and the carriage is located at the left margin, that is, when CRGPT=LM, CPT=0 is not present, so the carriage can be moved to the final printing position of the previous line. That is, the final print position of the previous line is calculated based on the carriage movement command stored in the line buffer 52, the carriage movement distance, and the paper feed amount.
Can be reproduced in reverse. Even if the previous line is printed with a blank digit from the left margin, the line buffer 52
In this case, the character type that corresponds to the space is stored in the address in the digit before the first printed character in the previous line, the printing pitch at that time is stored in the address, and the information of non-printing is stored in the address as the printing type. Since it is memorized, the MPU 44 can move the carriage to the final printing position of the previous line by decoding it in the reverse order of the key input order.

In such a system configuration, the control sequence begins when power is applied to the electronic typewriter. Immediately after turning on the power, the control units 24, 16, 9L, 49, etc. shown in FIG. 3 are initialized. After this, all the registers 51 in FIG. 3 are cleared, the row buffer 52 is cleared, and the flags 50 are cleared. After this, all the information in the register group 51 is stored in the non-volatile memory 57 shown in FIG. 3 in order to reproduce the previous usage state, so it is recalled to the register group 51. At this time 51
PITCH in Figure 2 according to the information in each register,
LINE, SPACE, RM CONTROL,
Re-light the OPERATING CONT lamps and also turn on the carriage indicator lamp. Also, flag KB2 is also auxiliary memory 5.
7, so do the same and KB
The SELECT lamp can also be lit.

As described above, no matter when the power is turned off or there is a power outage, the state immediately before the power is turned off can be reproduced after the power is turned on. Next, when any key is pressed, the process moves to a key determination sequence. In other words, a distinction is made between character keys and control keys. The determination is made based on the value of the key information. In other words, when wiring each key on the key matrix 88 in FIG. Boundary values occur between groups of . Therefore, by comparing the boundary value and key information, it can be determined which category it belongs to. If the determination result is a character key, management processing for the row buffer 52 is performed. In addition,
The SPACE key and RETURN key belong to the character keys as shown in Figure 2. If the determination result is a control key, it is checked which control key it is, and a control sequence corresponding to each control key is executed.

7 and 8 show the basic control sequence of row buffer processing. In FIG. 7, when the character type, print pitch, and print type are stored in the line buffer 52 shown in FIG. 6 by character key input, the register LEPT shown in FIG. 5 is increased by one unit. Also DCRGPT
is also increased by one character. Next, the register in Figure 5
Refer to OPCONT and branch accordingly. If the contents of register OPCONT in register group 51 are C, each character is printed, so immediately
Moving on to the printing process called BFPRT, the display 9
4 will be displayed sequentially. However, in the case of W or L, it is checked whether the type of character key is SPACE or RETURN, and if the general character key is neither, printing is not executed yet and only sequential display is performed. Now W, when printing each word, RETURN and SPACE
Printing is started by pressing either of the keys, and in the case of L, that is, printing by line, printing is started by pressing only the RETURN key. This realizes printing for each character, displaying and printing for each display word, and displaying and printing for each line.

If a new character is input after the character type, print pitch, and print type have been written to the storage area 0 to n of the line buffer 52, the entire line buffer 52 is shifted to the left three times and LEPT and PRTEPT are set to 1.
only decreases. As a result, the three types of information in the leftmost 0th digit of the row buffer 52 are removed, and the nth information area becomes empty. Therefore, it is sufficient to store a new (n+1)th character type, print pitch, and print type in the nth information area. Also, SPACE key,
Even when the RETURN key is pressed, information related to these items is sequentially stored in the line buffer 52 as shown in FIG. 6, so characters can be corrected at any time as long as the information is stored in the line buffer 52. That is, as mentioned above, when there is a space as character type information, the print pitch information and non-print information are stored, and similarly in the case of the return key, the carriage movement amount and paper feed amount are stored, so in any printing form. Even if it is, it becomes possible to make accurate retroactive corrections.

Printing is performed by the print processing control sequence BFPRT shown in FIG. Figure 8 LEPT=
PRTEPT? Compare LEPT and PRTEPT, and if they do not match, print characters, then increase PRTEPT by 1 unit and CRGPT by 1 character. Is this operation LEPT=PRTEPT? This continues until a match is reached. In other words, BFPRT processes the unprinted portion of the line buffer 52. Of course, when this process is finished, PRTEPT and LEPT are equal,
CRGPT and DCRGPT will be equal.

Next, we will explain how to register a character string (sentence), display it as a reference, and print it.

Key operations when registering a character string or sentence in memory are performed as shown in FIG.

Operate the OP.CONTROL key so that the STORE lamp is lit. Next, press the MEMORY key, the MEMORY key lamp will light up,
Informs the operator that the character string is being registered in memory. Next, a title name is input as a heading, the entire contents are displayed on the display 94, and when the title name input is completed, the RETURN key is pressed. At this time, the title name just entered is printed, the carriage returns, and the printing paper is line-fed. Also, at this time, if the same title name exists elsewhere, a warning is generated. After that, enter the character string to be registered and display it one by one, and print and register the character string with the RETURN key. When you press the MEMORY key, the title name is registered corresponding to the character string (sentence),
The MEMORY key lamp turns off. If you press the ☆ key while inputting a character string, it will serve as a temporary stop instruction for printing when a character string is called up from memory and printed.

Next, the operation of registering a character string (sentence) will be explained with reference to FIG.

In Figure 10, MPU44 in Figure 3 is the first
MEMORY when you know that the MEMORY key has been pressed
The key lamp is lit, then the flag STR of flag group 50 is checked, and the character string is registered (STR
=1) or reference (STR=0). Flag STR is OP.CONTROL
It is set by selecting STORE. In the case of a character string reference, the control sequence is transferred to the MRD in FIG. 12. In the case of character string registration, the next KEY INT, that is, the state of waiting for the key. After this, since neither the MEMORY key nor the RETURN key has been pressed yet, proceed to the next step and enter the title name using the character keys for registration. An operation of storing the data and sequentially displaying it on the display 94 is performed. After entering the title name, the RETURN key is pressed as shown in Figure 9, and in Figure 10, the RETURN key is pressed.
RETURN? Proceed to YES. As shown in the figure
Check the flag TR by pressing the RETURN key. In the initial state, the flag TR is reset, so the process proceeds to the print processing routine BFPRT, and the title name is printed. then flag
TR is set to 1, the title name in the row buffer 52 is saved in the WORK register, and the MPU 44 compares the title name in the WORK register with all the title names in the text memory 54 to perform a title name check.

If the same title name is already registered in the text memory 54, an error sound is emitted at 42 to warn. The MEMORY lamp also turns off.

If there is no same title name, the next character string (sentence)
Wait for key for registration Enter KEY INT and wait. When the title name is saved from the row buffer 52 to the WORK register, the title name in the row buffer 52 is cleared. However, since the title name in the WORK register is now sent to the display buffer in the display control unit, the display of the title name on display 94 is maintained.

Further, when the RETURN key is pressed, the printing paper on which the title name is printed is fed one line, and the carriage returns to the left margin position.

At this time, the carriage return command, the carriage movement distance from the left end reference position, and the paper feed amount at that time are stored in the row buffer 52 in the order of key operations as shown in FIG.

Also, when the carriage is moved to the right using the SPACE key, the space, print pitch, and print type (no print) information are stored as shown in Figure 6. These pieces of printing-related information are successively moved to the WORK register and text memory 54 together with the title name and character string (text) information. Furthermore, when this is called up for display or printing, the above-mentioned related information is removed and only character information is displayed or printed.

When I enter a character string (sentence) for registration, is it a character?
The process advances to YES, and character strings are sequentially stored in the row buffer 52 starting from the first digit in the LBFSTR shown in FIG. 7, and are sequentially displayed on the display 94. When one character string (sentence) has been input and the RETURN key is pressed, the flag TR in FIG. It also enters LBFSTR, and the character information in Figure 7 = RETURN? Proceed to YES,
A character string (text) is printed using BFPRT.

The next character string registration is performed by repeating the above operations. During this time, the contents of the row buffer 52 are not cleared, and only disappear from the first digit when overflow occurs. This is useful when making corrections, etc., as described above.

When the MEMORY key is pressed at the end of character string (sentence) registration, a title name is registered in the text memory 54 in correspondence with the character string (sentence) registered this time, as shown in FIG. The MENORY lamp goes out and flags STR and TR are reset.

Next, a key operation method for reference display and reference printing of character strings is shown in FIG.

Start by operating the OP.CONTROL key so that the STORE lamp is not lit.
Press the MEMORY key. At this time
The MEMORY key lamp lights up to inform the operator that the operation of reference display and reference printing of character strings or sentences can be started. The operator selects between character string reference display and character string reference printing. That is, in the case of reference display, press the NONPRT key. When the NONPRT key is pressed, the NONPRT key lamp lights up, clearly indicating to the operator that the character string reference display state has entered.

The first operation performed upon entering the reference display state is to input a title name. It goes without saying that the title name to be entered must be the same as the title name entered at the time of registration. Thereafter, if the operator wishes to perform reference display from a specific character string in the text, he or she presses the ☆ key, then inputs the specific character string, and presses the RETURN key. If you want to display the text as a reference from the beginning, you can press the RETURN key after inputting the title name.

When the RETURN key is pressed, a string of, for example, 20 characters from the beginning of the sentence is displayed. At this time,
The cursor position on the display 94 can be shifted word by word by key operation.
At the same time, deletion, insertion, etc. can be performed using the BACKSPACE key, <x key, etc. If you want to end the reference display, just press the MEMORY key.
If the character string is referenced and displayed and the user wishes to erase all of the character string, the CLR key is pressed while the character string is displayed on the display 94.
The NONPRT key lamp and MEMORY key lamp turn off when the MEMORY key or CLR key is pressed.

Next, the state of selecting reference printing will be explained. There are at least three types of printing formats: the first type prints the entire string (sentence) corresponding to the title name without a title name, and the second type prints the entire string (sentence) corresponding to the title name, and the second type prints the entire string (sentence) that corresponds to the title name. Type 3 is a string (text) that prints all of the character strings (text) that correspond to the title name with a title name.
Only two lines are printed. These instructions include "/0", "/1", "/" after entering the title name.
2" and press the RETURN key. Of course, "/0" may be omitted in the first type of instruction. Printing starts immediately after pressing the RETURN key. As mentioned above, if you enter the ☆ key when registering a character string, you can pause the printing once it has printed up to that location. In addition, the operator can also temporarily stop printing at will by pressing the ☆ key during printing.
To resume execution, press the ☆ key again.
After printing a character string or sentence corresponding to a certain title name, if you want to print the same content again, simply press the RETURN key. Also, if you directly press "/" and "2" without entering the third type of title name, all registered title names will be printed with two lines of text. To exit this mode, press the MEMORY key. At this time, the MEMORY key lamp goes out, indicating to the operator that the memory operation has been completed. Next, the internal operation based on the above-mentioned key operations will be explained.

When flag STR=0 in Figure 10, Figure 12
It was mentioned earlier that the control sequence is transferred to the MRD. The beginning of MRD is the key wait state KEY INT, as in the case of FIG. 10. After this, the type of key pressed is checked.

As shown in FIG. 11, the operator determines whether to refer to a character string or text on the display 94 or on the printing device 41.

That is, if you press the NONPRT key next time, the character string registered in the text memory 54 using the display 94 will be displayed.
Reference texts, etc. by entering the title name.

If a title name is entered without pressing the NONPRT key, a character string, text, etc. will be printed on the printing paper of the printing device 41 for reference. Since the contents of the registered character strings, sentences, etc. can be reproduced using these methods, it is possible to quickly determine whether or not they can be used for the current document creation. Also, partial corrections can be easily made on the display 94.

Especially when referring to text, it is difficult for operators to memorize all the text on displays with limited capacity.
Printing out the entire text is extremely convenient for further proofreading. Now, in order to refer to and display the registered character string (sentence) using the display device 94.
Press the NONPRT key. This sets flag NP to 1.

Title name of the character string (sentence) you want to refer to next, such as “NO3” or “NEW YEAR′ S CARD”
etc. are input from the keyboard 10.

When the title name is input, the process moves to the line buffer processing routine LBFSTR described above, and the title name is stored in the line buffer 52 as shown in FIG. 7, and the title name is displayed on the display 94.

This allows you to check whether the title name of the character string (sentence) to be referenced is correct, and if it is correct, press the RETURN key.

At this time, flag TR is checked. In the initial state
TR is reset to 0, so TR=1?
If this is the case, the answer is NO and TR is set to 1.

Next, the title name stored in the row buffer 52 and displayed on the display 94 is stored in the register group 51.
The data is saved to the WORK register for continuous display and the row buffer 52 is cleared. At this time, since the plug NP has been set to 1 by the RETURN key, the character string (text) corresponding to the title name is displayed on the display 94. This is the title name and text memory 54 stored in the WORK register.
The MPU 44 compares the title names inside.
The display device 94 has a display capacity for, for example, 20 characters,
It is possible to roughly estimate whether or not the character string (sentence) can be used for the purpose. In addition, the display 9
When the title name is displayed in 4, the character string (sentence) corresponding to the displayed title name
If you want to erase everything, press the CLR key. At this time, CLR in Figure 12? Proceed to YES, and then
Since the flag TR is set to 1 by pressing the RETURN key, is TR = 1? Press to proceed to YES, and select text memory 5 corresponding to the displayed title name.
Clear all title names and character strings (sentences) in step 4.

In addition, the title name and character string (text) are displayed on the display unit 94.
You can also delete or correct the displayed character string word by word using the keys while the reference display is displayed. Also, after entering and displaying the title name,
Reference display can be started not only from the beginning of the character string (sentence) but also from the middle of the character string (sentence).

At this time, the operator first presses the ☆ key and checks the flag TR. Since the RETURN key is not pressed at this time, TR=0, and after setting TR to 1, the flag SC is also set to 1. Thereafter, the displayed title name is saved in the WORK register and the line buffer 52 is cleared. However, the title name display is maintained by the saved WORK register. Then the string (sentence)
When inputting a search character string for a mid-way search, it is stored in the line buffer 52 by LBFSTR as in the previous example, and the search character string is displayed on the display 94 in place of the title name.
When the RETURN key is pressed, the flag TR is checked and set to 1 by the ☆ key.
TR=1? Then it goes to YES, and the flag SC is also set to 1, so SC=1? Proceed to YES and enter the search string stored in row buffer 52.
Save it to the WORK register and keep it displayed.
The flag NP is set to 1 by the NONPRT key, so proceed to YES, and the corresponding character string (sentence)
The following character strings (sentences) are displayed on the display 94 starting from the middle string (sentences).

For example, if an example of a search character stored in the WORK register is "NEW", the MPU 44 searches for a location matching the character string starting with "NEW" from the beginning of the relevant character string (sentence) in the text memory 54, and searches for that location. The following string (sentence) will be displayed. This allows you to quickly reference the desired location. Continuing the same character example "NEW"
If you want to display part way from another part starting with , press the ☆ key again, flags TR = 1, SC = 1, so proceed to YES, check flag NP, and since it is 1, display the text in the string (sentence). The following character strings (sentences) are displayed from other examples of characters starting with "NEW". Further, the above can also be done using the printing device 41. To do so, enter the title name without pressing the NONPRT key. The title name is displayed on the display 94, and after inputting it, the ☆ key is pressed.

As in the previous example, flags TR and SC are set to 1, the title name in the row buffer 52 is saved and displayed in the WORK register, and then when a search character string is input, the title name on the display disappears and a character example is displayed. , when you press the RETURN key, flag TR = 1,
Since SC=1, the search character example is saved in the WORK register and displayed. At this time, the NONPRT key is not pressed, so the flag NP = 0 and the process advances to NO, and the printing device 41 prints the character string (sentence) starting from the search string among the character strings (sentences) corresponding to the input title name. Print it. During this printing,
Since the search character string continues to be displayed on the display 94, if a selection error is discovered, printing can be immediately stopped by pressing the ☆ key. Furthermore, when simply referring to a registered character string (text) using the printing device 41, the operator can select one of the three printing formats described above.

That is, this is a case where all character strings (text) corresponding to the title name are printed without the first type of title name.

In this case, after inputting the title name from the keyboard 10, press "/" and "0", and then press the RETURN key. As in the previous example, the flag TR is initially 0, so proceed to NO, set the flag TR to 1, and save the title name to the WORK register. Of course the flag NP is not pressed now, so proceed to NO and enter the information of "/" and "0" after entering the title name.
When the MPU44 makes a determination, the character string (text) corresponding to the title name is printed on the printing paper without the title name.
and all print-related information are sent from the text memory 54 to the line buffer 52 and printed. At this time, since information such as space, carriage return, print pitch, paper feed amount, etc. was registered in the text memory 54 together with the character information at the time of character registration as described above, it is possible to reproduce exactly the same format as the format at the time of registration.

This allows the registered character string (text) to be used immediately for the task at hand.

Also, since the title name continues to be displayed on the display 94 during printing without a title name, if a mistake in title name selection or key input is found, the user can press the ☆ key to interrupt printing. This is extremely preferable since printing time and printing paper are not wasted. You can also make as many copies as you like by pressing the RETURN key the required number of times.

For type 2 and type 3 printing, input "/""1","/""2" after inputting the title name as in the previous example.
44 can be detected and discriminated, and the entire character string of the title name or only two lines can be selectively printed.
At this time, the title name continues to be displayed. Also, in the case of type 1 and type 2 printing, if you press the ☆ key at an appropriate delimiter when registering, printing will automatically stop after that point.

The processing is completed by pressing the MEMORY key. This allows MEMORY lamps and
The NONPRT lamp turns off. In addition, if a title name is not input in the third type, when the RETURN key is pressed to save the title name to the WORK register, the MPU 44 detects and determines the title name zero.
All the title names registered in the text memory 54 and only two lines of character strings (text) corresponding to them are printed along with each title name, so the current registration status can be quickly viewed and checked. Highly preferred. The amount of character strings (sentences) can be selected as appropriate using the number key next to the slash key "/".

Next, registration and calling of page formats will be explained. For example, as shown in FIG.
Even if the entry points of are different for each row, all these entry points EP1 to EP
It would be convenient if 11 could be registered and the carriage could be automatically moved to the entry point during printing and paper feeding. In order to satisfy such functions, this example further includes a page format registration function and a call function.

To register the page format, as shown in Figure 14, the first operation is to operate the OP.CONTROL key so that the STORE lamp lights up. next
Press the FORMAT key to declare the start of page format registration. At this time, the FORMAT key lamp lights up, indicating FORMAT-related registration. Next, enter the title name for the page format. The page format title name must start with an alphabetic character. That is, this is to distinguish it from the title name when registering the tab stop position, which will be described later. The delimiter for inputting a title name is the press of the RETURN key. After that, the title name is printed, and one line of printing paper is fed, indicating that the input title name has been accepted. However, as in the previous example, if the same title name is registered elsewhere, a warning will be given and the application will not be accepted. First, the operator moves the carriage to the entry point on the first line of the printing paper using the SPACE key, presses the ☆ key, and designates the entry point. When you have completed all input in one line in this way, press the RETURN key to instruct all entry points in one line to be memorized. Repeat this process, and when the page format has been memorized, press the FORMAT key to register it, turn off the FORMAT key lamp, and indicate to the operator that the page format has been accepted. The entry point is shown in Figure 13.
One blank line is set between EP10 and EP11, but in this case, RETURN after setting EP10
Then press the RETURN key without the ☆ key. FIG. 15 shows the operating procedure for calling up the registered page format. First, the OP.
Operate the CONTROL key to prevent the STORE lamp from lighting up. Then press the FORMAT key. At this time, the same as when registering the page format
The FORMAT key lamp lights up. Next, enter the title name and press the RETURN key to finish entering the title name. The page format registered at this point is recalled, so each time the ☆ key is pressed, the carriage moves to the next tab stop position. Therefore, by inputting the character string to be printed after pressing the ☆ key and repeating this process, a document in the format shown in FIG. 13 can be created many times. To exit, just press the FORMAT key. At this time, the FORMAT key lamp turns off.

Next, registration and calling of tab groups will be described. If you have defined one or more tab stop positions EP6, 9 and EP7, 10 in a certain format, for example, Fig. 13, and you want to redefine the tab stop for another line, you can set the position of one or more tab stops EP6, 9 and EP7, 10 for another line. The tab stops for are cleared and disabled. Therefore, if you want to save the currently defined tab stop position, it is useful to register the tab stop position within one line and recall it again. FIG. 16 shows the procedure for registering the tab stop position. First, set OP.CONTROL to , press the FORMAT key, and then enter a specific title name. Here, if the same title name has already been registered, a warning will be given as in the previous example and the entry will not be accepted.
However, this title name must start with a number. After inputting the title name, when the RETURN key is pressed, the tab stop position information previously stored in the registers TAB1 to TABn by the SPACE key, SET key, etc. is registered in the text memory 54.
This calling procedure is shown in FIG.
Set OP.CONTROL to STORE and FORMAT
Enter the title name of the registered tab group next to the key, press the ☆ key next to the RETURN key, and the carriage will be automatically set to the first registered tab stop position.

The operation of the above-mentioned key operations will be explained below.

When the MPU 44 learns that the FORMAT key has been pressed, the control sequence moves to FORMAT in FIG. First, clear the line counter LC that counts the number of lines on the print paper, then check the flag STR, and when it is 1 according to the STORE setting of OP/CONTROL, register the page format or tab stop position. Moshi flag STR
When =0, a page format call or a tab stop call is performed as shown in FIG.

In FIG. 18, when flag STR=1, a key wait state is entered.

When the title name is entered, the line buffer management routine LBFSTR is entered as in the previous example, and line buffer 52 is entered.
The title name is also displayed on the display 94.

RETURN to indicate the end of title name input
Press the key. At this time, since flag TR = 0, the title name is printed in the print processing BFPRT routine, the carriage is returned to the left margin position, and 1
Start a new line and set flag TR to 1. Next, the contents stored in the first column of the row buffer 52 are examined. If this is a number, proceed to YES, and since this is the registration of the tab stop position, use the title name that starts with the number stored in the line buffer 52 and the title name just before that, and write the tab stop position information stored in the TAB1 to TABn registers as a text. memory 5
Register on 4.

If the title name starts with an alphanumeric character, it is a page format registration, so line buffer 5
Save the title name of 2 to the WORK register and display it. Move the carriage to the entry point position using the SPACE key, press the ☆ key,
The contents of CRGPT, that is, the carriage position information (movement distance from the left end reference point) are saved to the WORK register. The entry point is Figure 13 EP2,
If there are multiple numbers like 3 and 4, press SPACE key, ☆
The contents of CRGPT are stored in the WORK register in sequence by pressing the key repeatedly. When you have finished registering one line of entry points, press the RETURN key. Since the flag TR is now set to 1, the process advances to YES, sets the line counter LC from 0 to 1, and stores its contents in the entry point storage section of the WORK register.

Repeat the above operation for the number of lines in the page format, store the entry point information for each line in the WORK register, and press the FORMAT key to store the contents of the WORK register, that is, the title name, the number of lines for each line, and the entry point information for each line as text. The page format is registered in the memory 54, and the FORMAT lamp is turned off to complete the page format registration.

To call up this registered page format, set OP.CONTROL to something other than STORE, so when you press the FORMAT key with flag STR=0, STR=1 in Figure 18? The process advances to NO and is executed by FMRD shown in FIG. Enter the title name of the desired page format or tab stop, use LBFSTR to display the title name,
TR=1 with RETURN key? The process is the same as the previous example until the result is NO. Here, the first digit of the line buffer 52 is checked, and if the title name starts with a number, that is, a tab stop, the tab stop position information corresponding to the title name in the text memory 54 is TAB.
Transfer to registers 1 to TABn and reset tab stop. Save the contents of this TAB register to MPU4
4, the tab stop position information previously used is reproduced, and automatic tab setting of the carriage is performed.

Since a title name starting with an alphanumeric character is a page format, the corresponding page format in the text memory 54 is transferred to the WORK register,
Set flag TR to 1. Thereafter, when the ☆ key is pressed, the entry point information in the WORK register is taken in by the MPU 44, and the carriage is automatically moved to and set at the entry point. In the example in Figure 13, RETURN from EP1 to EP11.
Pressing the ☆ key 11 times without a key automatically sets the carriage and automatically feeds the printing paper. This is because the text memory 54 stores the carriage return command, paper feed amount, etc. by pressing the RETURN key at the end of each line when registering the page format.

Also, when calling from this text memory 54, the PITCH set on the keyboard 10 at that time,
LINE SPACE and OP.CONTROL are ignored, and the content at the time of registration in the text memory 54 takes priority. For example, even if OP.CONTROL is set to print every word W, if you call the page format and set the carriage to the entry point with the ☆ key, then press one of the letter keys, the LBFSTR in Figure 19 will be printed.
The BFPRT routine does not pass as shown in Figure 7, but the next TR = 1? By going to YES and executing the BFPRT routine again, each character is printed, that is, OP.
Operate in CONTROL=C mode.

As a result, printing from the entry point is 1
Printing can be executed each time a character key is input, which is extremely convenient. As in the previous example, when calling this page format, the title name of the page format is
During this operation, as it continues to be displayed by LBFSTR,
It is extremely desirable to be able to discover mistakes in registration page format selection at any time.
