Abstract

PURPOSE:To make it possible to perform accurate registration of information, in a small document printer, by issuing an alarm when the same information as the character line or sentence information or the page format information of already stored title information is inputted. CONSTITUTION:The title name relating to a page format is inputted by key operation but an alarm 42 is issued when the same title name is registered in sentence memory 54. When there is no same title name, a carriage is moved to the first line name, a carriage is moved to the first line entry port of printing paper by a SPACE key to indicate memory and, thereafter, this operation is repeated to an n-th line and a FORMAT key is pushed to perform the registration of said title name. After the title name is inputted, the tab stop position informations stored in registers TAB1-TABn are registered in the sentence memory 54 by the SPACE key or a SET key. By this method, accurate character line or sentence information, page format information and tab position information can be registered by easy key operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electronic equipment such as small word processors and electronic typewriters.

Conventionally, this type of electronic equipment has required a certain amount of time to become familiar with it before it can fully utilize its functions.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide an electronic device that can perform sophisticated tasks with easy key operations.

Next, the basic configuration of the electronic device 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 knob 1 is pushed inward, the internal drive pulse motor
The structure is such that the connection with the knob 1 is removed and the knob 1 can be rotated manually. 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 to the end line of the paper, and the operator adjusts the indicator 3 vertically as shown by the arrow in advance according to the vertical length of the paper and places it on the platen 17.
When the upper side of the paper that has passed through 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 for suppressing the impact sound of impact printing, and is made of transparent acrylic, so it is easy to see the printed characters 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 characters per inch, 12 characters, 15 characters per inch, and provocal spacing (hereinafter referred to as PS) where the printing pitch changes depending on the size of the type. ing. Scale 8 has a pitch of 10 characters, 12
It has three scales engraved at a character pitch and a 15 character pitch, and the carriage indicator 12 has three LEDs.
A lamp mounted on the carriage and corresponding to the pitch designated from the keyboard 10 is lit to indicate the carriage position on the scale 8.

The keyboard IO includes a group of character keys 10a for inputting and printing characters.
and a group of control keys 10b and 10c arranged on both sides thereof, and 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. In the case of a key to be displayed, data is sent from the main control unit 7 to the control unit of the display 94, and the data is sent to the control unit of the display 94.
4 is displayed. In the case of a key to change the illumination of the lamp on the keyboard, such as a print pitch switch, nine-line feed pitch switch, or an illuminated key, the data to control the lighting of the lamps is sent from the main control unit to the keyboard control unit. Ru.

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. PITC
Each time the II key is pressed, the display section L1, which is made up of lamps such as LEDs related to PITCH, changes to 10, 12, 1.
5. In order of PS.

Moreover, it lights up cyclically. 10,12゜15 is the number of characters/1nch, but PS is 1 depending on the characters printed
The number of characters per inch varies. The LINESPACE key indicates the line feed amount, and the basic unit length 1 of the feed amount is 17.
It is set to 6 inches. As before, the lamp L2 is lit cyclically by pressing the key. KB5EL
The ECT key is used to select letters that cannot be selected even when using the 5HIFT key, which specifies uppercase and lowercase letters, i.e. a single key like KI[I that corresponds to three types of typefaces. This gives a temporary meaning, and in this example, when the KBI lamp L3 is lit, r

Each time the key is pressed, either the I or U lamp lights up.

The R, M C0NTR0L keys in the upper right corner instruct the functions of the electronic typewriter in the right margin. J
Either UST, AUTO, OFF is 26M C0N
It is selected each time the TR0L key is pressed. This is also indicated by the lighting of lamp L4. When the JUST lamp is lit, select the right justification function, and when the AUTO lamp is lit, auto line feed is performed.

OFF literally does not instruct anything. OPI:0NTRO
The L key is used to determine the print mode of the electronic typewriter. As before, each time you press a key, C, W,
Either L or 5TORE lights up to indicate the print mode. C means printing every character, W means printing every word, L means printing every line, and 5TORE means registering in the internal storage device. 5TORE means printing every line.

The 55wt on the left edge is related to the decimal tab function and is related to the 3-digit scale. That is, when 55w1 specifies SP, 3-digit scale is performed using a space, and when ``,'' is specified, 3-digit scale is performed using ``,''. If "XX" is specified, 3-digit scale is not performed. 5SW2 indicates the type of character.

The DECTAB key is used when specifying the decimal tab, etc.
The AYOUT key has a lamp and is used to instruct column layout, etc. The INDEXT key also has a lamp, and the FORMAT key also has a lamp to instruct automatic indent mode, etc. When related to page format, the MEMORY key also has a lamp. With a lamp, when related to memory, when the MARREL key is operated beyond the left and right margins, etc., N0NPR? The key is when referring to the text memory,
The REPEAT key is used when printing or inputting the same character continuously, or when moving the cursor position on the 4-key display 94.
The E key moves the print position towards the left margin.
■The key is used to erase characters, the INDEX key is used to advance one line of printing paper, the REVINDEX key is used to advance one line of printing paper in the reverse direction, and the C0DE key has a lamp and is used in conjunction with other keys. The CENT key has a lamp, and when instructing centering printing, the ☆ key instructs to cancel printing, etc., LM main key left margin setting, RM main key right margin setting, SE
The T key is used to set a tab stop, the CLR key is used to delete a tab stop, the RELOC key is used to move the carriage to the final print location, etc. The 5) IIFT key on the left is used in conjunction with other keys to enter lowercase letters or When instructing a special function, the LOCK key above is used to lock the 5HIFT key.

The BACK-TRACE key is used to go back to the previous line and correct printing.

The character key GK is inside the dotted line. The 5PAGE key is executed every time the carriage is pressed to the right to set a blank digit. The RETURN key returns the left margin of the carriage and feeds one line of printing paper.
The ETURN key and the 5PACE key are included in the character keys GK.

Information to be printed during the printing operation of the event position, etc. is stored. When making corrections, the MPU 44 finds out what characters have already been printed by searching this line buffer 52 in the reverse direction, and controls the carriage to automatically reach the final printing position of the already printed line. do.

Reference numeral 54 denotes a memory of character strings or sentences, and the character string 9 sentences and information registered by the operator according to appropriate procedures are not lost. The battery 23 is connected to the power sensor 56. It is monitored by the battery monitoring unit 55' as long as the power switch is turned on.
The voltage is backed up depending on the battery life, etc., and various operating modes etc. immediately before the power switch is turned off are stored.

The keyboard control unit 24 generates key information through a matrix 88 having grid points corresponding to each input key, and also displays the lamp or pitch of the illuminated key switch on the keyboard 10, the operating mode, etc. through the cathode driver 64. The lighting of the lamp 89 is also controlled. 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 . As mentioned above, 13 is a power supply unit that supplies power to each part.

In addition, each unit, memory, register group, flag group, etc. are connected to the MPU 44 via a data bus DB, and the
It receives control from U44 and sends various data to MPU44, where predetermined calculation 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 II is selected by pressing the KB5ELECT key (KB2=1). Therefore, when KB2=1, KIN in Figure 2 is a vertical line character rl
It becomes effective as the character key for J.

KB2 is cleared when ■ is selected using the KB5ELECT key. INDENT sets INDENT=1 when automatic indent mode is started.

When returning the carriage toward the left margin, it is always monitored, and when INDENT=1, the temporary left margin is used as the left margin. IN[1ENT is cleared when automatic indentation mode is canceled.

When 5TORE is selected with the 0P-CONTROL key, STR is set to 5TR=1, and when a selection other than 5TORE is selected, 5TR is set to O. TR is set to 1 when the title name is entered and the RETURN key is pressed during an operation such as character string reference, and when the character string reference is canceled, T
R=O. NP is set to 1 when the N0NPRT key is pressed, and NP is set to O when the reference to the character string is released. SC indicates that a search character string has been input, such as by character string reference. Therefore, when the reference character string is input, 5C=1, and when the reference to the character string, etc. is released, 5C=0. When the centering mode (any of the four types) is established, CMV
When MV=1 and centering is released, C
MV=O. TCNT is set to 1 when centering between tabs is specified, MCNT is set to 1 when centering is specified between margins, PCNT is set to centering between specified positions, and WCNT is set to 1 when centering is specified between words. It becomes l.

FIG. 5 shows the internal structure of the register group 51. Register P
RTEPT indicates the final point of characters stored in the line buffer 52. Register PRTEPT indicates the printing end point within the characters stored in line buffer 52. Register CRGPT indicates the position of the carriage from the left margin of the printing paper, and stores the distance traveled by the carriage from the left margin. In register 0CRGPT, when printing every word, spacing every 9 lines, etc., the carriage does not immediately move and print when a character key is input. Therefore, it is necessary to know and monitor the temporary carriage position. At this time, DGRGP
T is used to store the actual quantity to be moved. P
When the PITCH key is pressed to specify the character size, that is, the printing pitch, information on each printing pitch is stored in the ITCH. When the MPU 44 knows the printing pitch, the P I TC
Please refer to H. Like PITCH, LNSP stores the current paper feed amount, ie, the operating state of the LINE 5PACE key. RMC is R, M, C0NTR0L key, 0P
CNT stores the states of the OP and C0NTR0L keys.

LM and RM store the position of the right margin in the left margin at that time in the same unit as CRGPT and the like. 55w1
and S SW2 is 55w1゜5SW2 on the operation panel
The state of each is memorized. DLM is a register for saving the left margin LM in automatic indent mode.

From TABI, T A B n stores the position of the tab at that time, and its dimensions are the same as LM and the like.

WORK is used to temporarily store information, save information, etc. during control or processing. CPT indicates a certain point in the line buffer 52, corresponds to the character where the carriage is located, and is used for corrections, etc. 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 from the oldest character digit to the younger one like a first-in-first-out stack.
The PU 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.

f and C store the number of fed lines of printing paper.

FIG. 6 shows the internal structure of the row buffer 52. The unit storage units of the row buffer 52 are numbered from 0 to n. The character type, print pitch, and print type can be stored in the I, If, and lit addresses of each unit storage area, respectively. This information will be used for corrections and other purposes. (2) The character type of the address is printed character information taken in from the keyboard control unit 24 in FIG. 3, that is, character key information. In addition, the slide switch for this key manually (Fig. 2 S 5W2
) (5SW2 in the register group 51) corresponds to the type of printing at address ■. Further, the state of PITCH in FIG. 2 is also in PITCH in the register group 51, and this is stored as the print pitch at address . 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 TRAC: When the E key is pressed and the carriage is moved backwards and the carriage is located at the left margin,
That is, when CRGPT=LM, CPT=O does not hold, 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 character type corresponding to the space is stored in the line buffer 52 at address 1 of the first column before the first printed character of the previous line. Since the address ■ stores the print pitch at that time, and the address ■ stores the information of no printing as the printing type, the MPU 44 decodes the keys in the reverse order of the key input order to determine the final print position of the previous line. The carriage can be moved.

In such a system configuration, the control sequence begins when power is applied to the electronic typewriter. Immediately after the power is turned on, the control units 24, 16.9L in FIG.
49 etc. is 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 saved 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, PITCH and LINE 5PA in FIG.
CE, R, M C0NTR0L, 0PERATING
The respective lamps of C0NT are lit again, and the carriage indicator lamp is also lit. Furthermore, since the flag KB2 is also stored in the auxiliary memory 57, the lamp KB5ELECT can be lit in the same way.

As described above, no matter when the power is turned off or there is a power outage, after the power is turned on, the state immediately before the power is turned off can be reproduced. 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. 3, if the values of the character keys are made to be continuous, and the values of the control keys are also made to be continuous, then Boundary values arise between groups. Therefore, by comparing the boundary value and the key information, it is possible to determine which category it belongs to. When the determination result is a character key, management processing of the line buffer 52 is performed. Note that the 5PAGE key and RETURN key belong to the character keys as shown in FIG. 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.

Figure 7.8 shows the basic control sequence of row buffer processing. In FIG. 7, when the character type, print pitch, and print type are manually stored in the line buffer γ52 shown in FIG. 6 using the character keys, the register LEPT shown in FIG. 5 is increased by one unit. DGRGPT also increases by one character. Next, the fifth
Refer to register 0PCONT in the figure and branch respectively.

If the content of register 0PCONT in register group 51 is C, each character is printed, so immediately print BFPRT in Figure 8.
The process moves on to the printing process called ``5PACE'', and is displayed sequentially on the display 94. However, if it is W or L, it is checked whether the character key type is 5PACE or RETURN, and if the general character key is neither, printing is not executed yet. , only sequential display is performed. Now W, when printing each word, RETUR
Printing is started by pressing either the N or 5PACE key.
In L, that is, when printing line by line, printing is started only by pressing the RETURN key. As a result, printing of each character, display of each displayed word, and display and printing of every 9 lines are realized.

If the character type up to the O-n storage area of row buffer γ52,
After the print pitch and print type are written, when a new character is input, the entire line buffer 52 is shifted three times to the left and LEPT and PRTEPT are decreased by 1. As a result, the three types of information located at the leftmost column 0 in 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, printing pitch, and printing type in the nth information area. Also, 5PACE key, RET
Even when the URN key is pressed, information related to these 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 printing pitch information and non-printing information are stored, and similarly in the case of the return key, the carriage movement amount and paper feed amount are stored, so it is possible to store any printing format. Even if it is, it becomes possible to make accurate retroactive corrections.

Printing is performed using the print processing control sequence BFP shown in Figure 8.
This is done by R-cho. , FIG. 8 LEPT=PRTEPT
? Compare LEPT and PRTEPT with , and if they do not match, execute character printing, then print PRTEPT by 1 unit, C
Increase RGPT by one character. This operator is LEPT=

It becomes equal to PT.

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 and C0NTR0L keys so that the 5TORE lamp is lit. Next, when the MEMORY key is pressed, the MEMORY key lamp lights up, informing the operator that the character string is being registered in the memory. Next, a title name is input as a heading, the entire contents are displayed on the display 94, and when the title name is completed, the RETURN key is pressed. At this time, the title name just input 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.

Enter the character string to be registered from now on, display it one by one, and press RETU.
Print and register the character string using the RN key. MEMOR
When the Y key is pressed, the title name is registered in correspondence with the character string (sentence), and the MEMORY key lamp is turned off. If you press the ★ key while inputting a character string, it will be used as a pause instruction for printing when the character string is recalled from the memory and printed.

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

In FIG. 10, the MPU 44 in FIG. 3 is the first MEMO.
When I found out that the RY key was pressed, ME! Turn on the ll0RY key lamp, then turn on the flag STR of flag group 50.
is examined to determine whether the character string is registered (STR=1) or referenced (STR=0). Flag STR
is set by setting OP, C0NTR0L to 5TORE. In the case of a character string reference, the control sequence is transferred to the MRD in FIG. For character string registration, use the following KEY
It becomes INr, that is, a state of waiting for a key. MEMO after this
Since neither the RY key nor the RETURN key has been pressed yet, proceed to the next step and press the 1-character key to register the title, and the line buffer processing routine LBF shown in Figure 7 will be executed.
An operation is performed in which each character is stored in the STR, that is, in the row buffer 52, and sequentially displayed on the display 94. After entering the title name, the RETURN key is pressed as shown in Figure 9, and in Figure 10, the RETURN? key is pressed. Proceed to YES.

As shown in the figure, flag TR is checked 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. After that, set the flag TR to 1, then WORK the title name in line buffer 52.
The title name is saved in the register, and the MPU 44 compares the title name in the WORK register with all title names in the text memory 54, thereby omitting title name checking.

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

If there is no name, the system enters KEY INT and waits for a key to register the next character string (sentence). When the title name is saved from the line buffer 52 to the WORK register, the title name in the line 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.

When the RETURN key is pressed, the print sheet 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 carry from the left end reference position, the carriage movement distance, and the paper feed speed at that time are stored in the line buffer 52 in the order of key operations as shown in FIG.

Also, 5PAC: Space, print pinch, print type (no print) when the carriage is moved to the right using the E key.
Information is stored as shown in FIG. Information related to these prints is stored in WOR together with title name 2 character string (text) information.
Continuously move to the K register or text memory 54. 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 (communication) for registration, is it a character? YES
The character strings are sequentially stored in the LBFSTR shown in FIG. After inputting one character string (sentence), RETU
When the RN key is pressed, the flag TR in Figure 10 is set to l this time, so the character string (sentence) in the line buffer 52 is registered in the text memory 54, enters the LBFSTR again, and the character information in Figure 7 is stored. = RETURN? Proceed to YES and the character string (text) will be printed using RFPPT.

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

When the AEMORY key is pressed at the end of character string (sentence 'Q) 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. M.E.
The MORY 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.

OP, C: Start by operating the 0 NTROL key so that the L 5 TORE lamp is not lit. MEM
Press the ORY key. At this time, the MEMORY key lamp lights up, notifying the operator that reference display and reference printing operations for character strings or sentences can be started.

The operator selects between character string reference display and character string reference printing. In other words, in the case of reference display No5pRT
Press the key. N0NPP by pressing the N0NPPT key
The T key lamp lights up, clearly indicating to the operator that the character string reference display state has been entered.

The first operation performed when 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 manually at the time of registration. After this, the operator >,1. ! rIf you want to display a reference from a specific character string in the sentence ψ, press the ☆ key, then input the specific character 1j, and press the RETURN key. If you want to display the text starting from the beginning, press the RETURN key after pressing the title Meijinriki.

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 operating the N key or the N key, and at the same time the BACKSPAC
Deletion, insertion, etc. can be performed using the E key, the G key, etc. If you want to end the reference display, just press the MEMORY key. In addition, if you want to display this character string reference and erase all of the character string, the character string will be displayed on the display 94.
Press the CLR key while the screen is displayed. MEM
N0N when the ORY key or GLR key is pressed
The PRT key lamp and MEMORY key lamp go out.

Next, the state of selecting reference printing will be explained. There are at least three types of printing formats; the first type prints all the character strings (Bungo) corresponding to the title name without the title name, and the second type prints the entire character string (Bungo) that corresponds to the title name. Those that print all of the corresponding character strings (Bunka), and the third type is the one that prints all of the corresponding character strings (Bunka).
sentence, i2) Only two lines are printed. These instructions are entered after entering the tile name, rlo'', r/l
J.

All you have to do is input "/2" and press the RETURN key. Of course, "10" may be omitted in the first type of instruction. Printing starts immediately after pressing the RETURN key. As mentioned above, by inputting the ☆ key for a single character string, printing can be temporarily stopped when that location has been printed. The operator can also temporarily stop printing at will by pressing the ☆ key during printing. To resume execution, simply press the 11 H☆ key.After printing a character string or sentence corresponding to a certain title name, if you want to print the same content again, simply press R.
ETIJl? All you have to do is press the N key. If you directly press r/", r2" without entering the third type title name, the registered title fund 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.

As mentioned above, when flag 5TR=0 in FIG. 10, the control sequence shifts to MRD in FIG. 12. At the beginning of the MRD, as in the case of Fig. 10, the key waiting state is KEY IN.
It is T. 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, when the N0NPPT key is pressed next, the display 94 is used to refer to the character string 9 sentences registered in the sentence memory 54, etc., using the title master's power.

In the unlikely event that the N0NPPT key is not pressed, a character string, such as a sentence, is printed on the printing paper of the printing device M41 for reference. Character string 9 registered using these
Since the content of sentences etc. can be reproduced, it can be quickly determined whether or not it can be used for the current document creation. Also, partial corrections can be easily made on the display 94.

Particularly when referring to text, it is difficult for the operator to memorize the entire text if the display device has limited capacity, but printing out the entire text is extremely convenient for further proofreading.

Now, the user presses the N0NPPT key to reference and display the registered character string (sentence) using the display 94. This sets flag NP to 1.

Title name of the string (sentence) you want to refer to next, e.g. r
Enter N03J, r NEW YEAR'S CARDJ, etc. from the keyboard 10.

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

By doing this, check whether the title name of the character string (sentence) to be referenced is correct, and if it is OK, RETURN.
Press the key.

At this time, flag TR is checked. In the initial state, TR is reset to 0, so the determination of TR = 17 is NO.
Go to and set TR to 1.

Next, the title name stored in the line buffer 52 and displayed on the display 94 is saved in the WORK register of the register group 51 for continuous display, and the line buffer 52 is cleared. At this time, since the plaque 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 W.O.
Title name and text memory 54 stored in RK register
The MPU 44 compares the title names inside. The display device 94 has a display capacity of, for example, 20 characters, and it is possible to roughly estimate whether or not a character string (sentence) can be used for the purpose. In addition, when the title name is displayed on the display 94, if you want to erase all the character strings (text) corresponding to the title name that is pasted on the table, use the DLR
Press the key. At this time, the CLR in Figure 12? Proceed to YES, and press the RETURN key to set the flag TR to 1.
TR = 1 because it is set to Sera I? 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.

Furthermore, while the title name or character string (sentence) is being displayed for reference on the display 94, the displayed character string can be erased or stopped in units of Ugo by using the φ key or the Q key. Further, after inputting and displaying a 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 presses the flag TR.
Find out. At this time, since the RETURN key is not pressed, TR=O, and after setting TR to 1, the flag SC is also set to 1. After that, the displayed title name is saved to the WORK register, and the line/header 52 is saved.
Clear. However, the tile name display is retained due to the saved WORK register! be done. After that, when you start inputting a search character string to search from the middle of the character string (sentence), it is stored in the line buffer 52 by LBFSTR as in the previous example, and the display 94 uses the search string instead of the title name. A string is displayed. When the RETURN key is pressed, the flag TR is checked and is set to l by the ☆ key, so TR=1? Proceeds to YES, and the flag SC is also set to l, so SC=
The process advances to YES in step 17, and the search character string stored in the line buffer 52 is saved in the WORK register to continue displaying it. Since the flag NP is set to l by the N0NPPT key, proceed to YES and enter the character string (
The following character strings (sentences) are displayed on the display 94 starting from the middle string (sentence) of the sentence.

For example, if the search character string stored in the WORK register is rNEWJ, the corresponding character string in the text memory 54 (
The MPU 44 searches for locations matching the character string starting with rNEWJ from the beginning of the sentence), and displays the following character strings (sentences) from there. This allows you to quickly reference the desired location. Continue the same string r
N E' W If you want to display part way from another part starting with J, press the H☆ key again to set the flag TR=1,5C=
Since it is 1, proceed with YES, check the flag NP, and select ■
Therefore, the following character strings (sentences) are expressed from other character strings starting with rNEWi in the character strings (sentences). Furthermore, the second point can also be performed using the printing device 41. To do so, input the title name without pressing the N0NPPT 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 the character string is displayed. , press the RETURN key to set the flag TR=1. Since it is SC-1, the search string is 1Ii01'? Then save 2 tables to the register. At this time, the N0NPRT key is not pressed, so the flag NP = 0 and the process goes to NO, and the printing device 41 prints the character string (text) starting from the search character string among the character strings (text) corresponding to the input title name. Print it. During this printing, the search character string continues to be displayed on the display 94, so 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.

At this time, change the title name to "Keepo 1" and "10" after manual labor.
/j After pressing [0], press the RETURN key. As in the previous example, 7 lag TR starts with O, so proceed to NO, set flag TR to 1, and then WORK the title name.
Save to register. Of course the flag NP is not pressed now, so proceed to NO, and after the title Meijinriki (7)
r/ J, r OJ (1) Information W'ltM P U
44, the character string (text) corresponding to the title name and all print-related information are sent from the text memory 54 to the line bar shifter 752 and printed without the title name on the printing paper. At this time, as mentioned above, information such as space, carriage return, print pitch, paper feed, etc. was registered in the text memory 54 along with character information at the time of character registration.
It is possible to reproduce exactly the same format as the format at the time of registration.

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

Furthermore, 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 a manual key error is discovered, the printing can be interrupted by pressing the ☆ key. This is extremely preferable since printing time and printing paper are not wasted. Also, by pressing the RETURN key the required number of times, copies can be made even if the sheets are out of stock.

For type 2 and type 3 printing, input rlJ rlJ and rlJ r2J after the title as in the previous example.
U44 or detection 9 is determined, all character strings of title name and 2
Only 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 printing to that point.

The processing is terminated by pressing the MEMORY key.

This turns off the MEMORY lamp and N0NPPT lamp. Also, if you do not enter the title name in the third type,
When the RETURN key is pressed to save the title name to the WORK register, the MPU 44 detects the title name tree and saves all the title names registered in the text memory 54 and their corresponding character strings (sentence-t ;'L)2
Since only the lines are printed along with each title name, the current registration status can be quickly viewed and checked, which is extremely desirable. The string (sentence) foot is the slash key “/
You can select as appropriate using the number keys next to ``.

Next, registration and calling of page formats will be explained.

For example, even if the entry point of the printing paper P is different for each line as shown in Fig. 13, all these entry points EPI to EPI 1 can be registered and the carriage automatically moves to the entry point during printing and paper feeding. It is convenient to be able to move around. 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, C0NTR0L keys, and
Make sure the RE 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 and the FORMAT
Indicates AT-related registration. Next, enter the title name for the page formant. Page format title names must start with a letter. That is, this is to distinguish it from the title name when registering the tab string position, which will be described later. The input of the title name is interrupted by pressing the RETURN key. After that, the title name is printed, the printing paper is fed one line, and the input title name is shown to be added. However, as in the previous example, if the same title name is registered elsewhere, a warning will be given and no acceptance will be given. First, the operator moves the carriage 5P to the entry point of the first line of the printing paper.
Move using the ADE key, etc., and press the ☆ key to specify the entry point. In this way, when all input points in one line are completed, press the RETU'RN key to instruct to memorize all entry points in one line, and from now on, enter the second entry point.
Repeat the process up to the nth line (n-6 in the example in FIG. 13), and when the page format has been stored, press the FORMAT key to register, and turn off the FORMAT key lamp to indicate to the operator that the completion has been accepted. Note that in Figure 13, one blank line is set between EPIO and EPII (entry point), but in this case, R after setting EPIO
Just press the ETURN key and then the RETURN key without the warehouse key. FIG. 15 shows the operation procedure for calling up the registered page format.

First, operate the 0NTROL key at OP to prevent the 5TORE lamp from lighting up. Then press the FORMAT key. At this time, same as when registering the page format, F
The ORMAT key lamp lights up. Next, enter the title name and press the RETURN key to complete the title. The page format registered at this point is called up, 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 the input key and repeating this, a document in the format shown in pp l 3 ri can be created many times. To exit, FORM
All you have to do is press the AT key. At this time, the FORMAT key lamp goes out.

Next, registration and calling of tab groups will be described. a certain format,
For example, in Fig. 13, when one or more tab stop positions EP6.9 and EP7,10 have been defined, if you want to redefine the tab stop for another row, Tab stops 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. 1st
Figure 6 shows the procedure for registering tab stop positions. First, set OP, C0NTR0L to 5TORE, and FOR
After pressing the MAT key, enter a specific title name.

Here, if the title name of the inquiry has already been registered, a warning will be given as in the Mj example, and no acceptance will be made. however.

This title name must start with a number. After the title Meijinriki, press the RETURN key to proceed to 5P.
Register TAB 1 by AGE key, SET key, etc.
The tab stop position information stored in ~TAB n is registered in the text memory 54. This caller is shown in FIG. 17.

Set OP, CON, TR0L to 5TORE, FOR
If you press the MAT key, then the title name of the registered tab group, and then press the RET (IRN key), then the ☆ key, 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 recognizes 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 printing paper, then check the flag STR, and check whether it is OP or C0NTR.
When it is 1 due to the 5TORE setting of 0L, register the page former (y) or tab stop position. If flag 5TR=O, a page format call or a tab stop call is made as shown in FIG.

In FIG. 18, when flag 5TR=1, a key wait state is entered.

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

Press the RETURN key to instruct the end of the title. At this time, although flag TR=O, printing process B
The FPRT routine prints the title name, returns the carriage to the left margin position, prints a few lines, and sets the flag TR.
Set to 1. Next, the contents stored in the first column of the row buffer 52 are examined. YES if this is a number
Proceed to , and register the tab stop position, so use the title name starting with the number stored in the line buffer 52 and the t-c immediately before it, and input the tab stop position information stored in the TAB1=TABn register into the text. memory 54
Register.

When the title name starts with an alphabet, the title name of the line/li/shifter 52 is saved and displayed in the WORK register because it is a page format registration. 5PAG
Move the carriage to the entry point position using the E key, etc., press the Eclipse key, and read the contents of CRGPT, that is, the carriage position information (travel distance Ill from the left end reference point:).
Save to 0RK register. Entry points are shown in Figure 13, EP2 and 3.

If there are multiple keys as in 4, press the 5PACE key and the ☆ key repeatedly to store the contents of CRGPT in the WORK register in order. When entry point registration for one line is completed, R
Press the ETURN key. Since the flag TR is set to 1 this time, proceed with YES and set the line number counter LC to 0.
is set to 1 and its contents are correspondingly stored in the entry point storage section of the WORK register.

Repeat the steps in L for the number of lines in the page format, and then press W.
Store the entry point information for each line in the ORK register, register the contents of the WORK register from the number where the FORMAT key is pressed, that is, title name, number of each line information, and entry point information for each line, from text memo 1 to 54, and press F.
The ORMAT lamp is turned off and page format registration is completed.

The number to call this registered page format is OP
, since C0NTR0L is set to a value other than 5TORE, when the FORMAT key is pressed with flag 5TR = 0, the first
5TR = 1 in Figure 8? Proceed to NO and switch to FM in Figure 19.
This is done by RD. Enter the title of the desired page format or tabs I/tub and press LBFSTR.
Press to display the title name, and press RETIJRN +- to press T.
R=1? 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 checked.
Transfer to ABI-TABn register, - reset tab stop. 3℃ TAB register contents MPU44
By importing the tab stop position information, the previously used tab stop position information is reproduced, and automatic tab setting of the carriage is performed.

Since the title name starting with alphabent is a page format, the corresponding page format I in the text memory 54 is transferred to the WORK register, and the flag TR is set 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 and set to the entry point. In the example in Figure 13, RETU from EPI to 11
By pressing the warehouse key 11 times without using the RN key, the carriage is automatically set and the printing paper is automatically fed. This is the RET button pressed at the end of each line when registering the page format.
This is because the communication memory 54 stores the carriage 4 return command, one paper feed amount, etc. using the URN key.

Also, when calling from this text memory 54, the PITCH set on the keyboard 10 at that time.

LINE 5PAC:E, OP, C:0NTROL is ignored, and the content at the time of registration in the text memory 54 takes priority. For example, even if OP, C0NTR0L is set to print every word W, when you call the page format and set the carriage to the entry point with the ★ key, and then press one character key, the BFPRT routine in LBFSTR in Figure 19 is 7 It does not pass as shown in Figure 7, but the next TR = 1? DeY
Proceed to ES and execute the BFPPT routine again to operate in the mode of printing each character, that is, OP, C0NTR0L=C.

As a result, printing from the entry point can be performed manually for each character key, which is extremely convenient. As in the previous example, the title name of the page format is continued to be displayed by LBFSTR even when this page format is called, so it is very preferable that a mistake in the selection of the registered page format can be detected at any time during this operation.

As explained above, according to the present invention, when at least one of character string or text information, page format information, and tab stop position information is stored in the storage means in correspondence with title information, the information is already stored in the storage means. A warning will be issued when the same title information as the title information is input, so if the character string of the same title information or
In addition to preventing manual input of text information, it is also possible to print out the title information stored in the storage means.
Accurate character string or text information, page format information,
It becomes possible to register tab stop position information.
