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 disadvantages, it is an object of the present invention to provide an electronic device that allows advanced work to be performed 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 the paper and is used to ensure that the two printed sides face the operator even when thin paper is used. The page end indicator 3 is a pointer indicating the length to the end line of the paper,
The operator adjusts the indicator 3 in the downward direction according to the arrow in advance to match the vertical length of the paper, and places the paper until the top edge of the paper that has passed through the platen 17 reaches the scale position of the indicator 3. You can know the length up to the end line of the paper. 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 a horizontal printing pitch of 10 characters per inch, 1
There are four types: 2 characters, 15 characters, and proportional spacing (hereinafter referred to as PS) in which the printing pitch changes depending on the size of the type. The scale 8 has three wooden scales carved at 10-character pitch, 12-character pitch, and 15-character pitch, and the carriage indicator 12 is composed of 3 lamps such as LEDs and is mounted on the carriage. The carriage position is indicated on the scale 8 by lighting the lamp corresponding to the specified pin and inch.

The keyboard 10 has character keys Jim for inputting and printing characters.

10c, 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 to the control unit of the display 94,
It is displayed on the display 94. In the case of a key that changes the illumination of the lamp on the keyboard 10 by hand, such as printing pitch switching, single line feed pitch switching, or 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 more clear. FIG. 2 is a front view of the operation panel of the electronic typewriter of this embodiment.

OFF literally does not instruct anything. OP, C0NTR0
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 character by character EJ, ', W means word by word printing, L means line by line printing, 5TORE means registration in the internal storage device, and when 5TORE, the mode is line by line printing.

55w1 on the left edge relates to the decimal tab function and relates to the 3-digit scale. That is, when 5SWI specifies SP, three-digit scale is performed using a space, and when 5SWI specifies ",", three-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 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, and the MEMORY key also has a lamp when related to page formatting. With a lamp, when related to memory, the MARREL key is used to move beyond the left and right margins, and the N0NPPT key is used to move the cursor position in the text memory 94.

Addresses are assigned for PU processing.

Reference numeral 50 denotes a group of flags, which stores the specified state of the typewriter, various modes, etc. A group of registers 51 is used to store intermediate results of processing operations. 52 is a line buffer for storing information regarding already printed characters and for word units 9
Stores information to be printed during line-by-line printing operations. 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 for character strings or sentences, and the character string 1 sentence registered by the operator according to the appropriate procedure will not be 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.

Each unit, memory, register group, flag group, etc. is connected to the MPU 44 via a data bus DB, and the MP
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 (KB2=1) when ``■'' is selected by pressing the KB5ELECT key. Therefore, when KB2=1, Kl in FIG. 2 becomes effective as a character key for the vertical line character "1".

KB2 is cleared when ■ is selected using the KB5ELECT key. INDENT Set INDENT=1 when indentation mode is started. Always monitored when moving the carriage back towards the left margin,
When INDENT=1, the temporary left margin is used as the left margin. INDENT is cleared when automatic indent mode is canceled. STR is OP, C0N
When 5TORE is selected with the TR0L key, 5TR=
1 and select something other than 5TORE, 5TR=O. TR is set to 1 when the title name is input by operations such as character string reference and the RETtlRN key is pressed, and TR becomes O when the character string reference is canceled. N
P sets NP=1 when the N0NPRT key is pressed, and becomes NP=O when 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 a reference character string is input, 5C = 1, and when the reference to a character string, etc. is canceled, 5C
=0. CMV becomes 1 when a centering mode (any of the four types) is established, and becomes 0 when centering is canceled. T.C.
When NT specifies centering between tabs, TCNT=
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 P
RTEP 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, every 9 lines, etc., the carriage does not move immediately when a character key is input. Therefore, it is necessary to know and monitor the temporary carriage position. At this time 0CRGP
T is used to store the actual quantity to be moved. P
ITICH stores information on each print pitch when the PITCH key is pressed to specify the character size, that is, the print pitch. When the MPU 44 knows the printing pitch, it uses PITCH.
Please refer to . Like PITCH, LNSP stores the current paper feed amount, ie, the operating state of the LINE 5PAC:E key. RMC stores the states of the R, M, and C0NTR0L keys, and 0PCNT stores the states of the OP and C0NTR0L keys. LM and RM store the positions of the left margin and right margin at that point in the same unit as cRGpr, etc.

55wt and SSW2 respectively store the states of 55w1 and 5SW2 on the operation panel. DLM is a register for saving the left margin LM in automatic indent mode.

TABn stores the current tab stop position from TABI, and has the same dimensions 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, the status of the printed character type, printing pitch, etc. at that time is memorized for each character between characters, 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.

LC stores the number of lines fed on printing paper.

FIG. 6 shows the internal structure of row/header 52. The number O-n is stored in the unit memory of the row buffer 52.

Character types, print pitches, and print types can be stored at addresses I, n, and I11 of each unit storage area. 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 on register group 5) corresponds to the type of printing at address 111. 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 . Row buffer γ52
The length of is greater than the maximum number of characters to be printed per unit line, for example, when the carriage is positioned in the storage area for 2 lines of 300 characters, that is, when CRGPT=LM, CP
Since T=O, 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, a character type that corresponds to a space is stored in the one-line buffer 52 at address ■ in the digit before the first printed character in 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 unit 24, 16, 9L in Fig. 3,
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.
C: E, R, M C0NTR0L, 0PERATIN
Relight each lamp of G C0NT and also light the carriage indicator lamp. 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, 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, the third
When wiring each key on the key matrix 88 shown in the figure, 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, it is possible to create a line between the eye, the letter key, and the control key group. A boundary value occurs. Therefore, by comparing the boundary value and key information, it can be determined which one belongs to. When the determination result is a character key, management processing of the line buffer 52 is performed. Note that the 5PAC:E 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.

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 manually stored in the line buffer 52 shown in FIG. 6 using the character keys, the register LEPT shown in FIG. 5 is increased by one unit. 0CRGPT 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, one character has several spaces, so it is immediately converted to BFPPT in Figure 8.
The process moves on to a printing process called ``,'' and is sequentially displayed on the display 94. However, in the case of W or L, it is checked whether the type of character key is 5PACE or RETURN, and if it is a general character key that is neither, printing is not executed yet and only sequential display is performed. Now W, when printing each word, RETUR
Printing starts with either key N or 5PACE,
In L, that is, when printing line by line, printing is started only by pressing the RETURN key. This realizes printing of each character, display of each displayed word, and display and printing of every two lines.

If the character type is stored in the storage area 0 to n of the line buffer 52,
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. Mari5PAcE key, R
Even when the ETURN 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 there is a problem, it is possible to accurately shape and correct the problem.

Printing is performed using the print processing control sequence BFP shown in Figure 8.
Performed by PT. Figure 8 LEPT=PRTEPT

FPPT processes the unprinted portion of the line buffer 52. Of course, when this process is finished, the PRT
EPT and LEPT are equal, CRGPT and DC:RG
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 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. io.

In FIG. 10, the MPU 44 in FIG. 3 is the first MEMO.
When the press of the RY key is detected, the MEMORY key lamp is lit, and then the flag STR of the flag group 50 is checked, and the character string is registered (STR='l) 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 KjY
The state is INT, that is, waiting for a key. After this MEMOR
Since neither the Y key nor the RETURN key has been pressed yet, proceed to the next step and press the letter keys to register the title.The line buffer processing routine LBFS shown in Figure 7 above is executed.
An operation is performed in which each character is stored in the TR, 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, by pressing the RETURN key, the flag T
Check R. In the initial state, the flag TR is reset, so the process proceeds to the print processing routine BFPPT.
The title name will be printed. After that, set 2g TR to 1 and WORK the title name in rowpa sofa 52.
The title name in the WORK register is compared with all the title names in the text memory 54 by the MPU 44 to check the title name.

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

If there is no same title name, the process enters the key wait key INT for registering the next character string (text) and waits. 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/<.file in the display control unit, the display of the title name on the 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 carry button is returned 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 line buffer 52 in the order of key operations as shown in FIG.

Also, when the carriage is moved to the right using the 5PACE key, the space, printing pitch, and printing type (no printing) information are stored as shown in FIG. Information related to these prints is included in WORK along with title name 9 character string (text) information.
The data is sequentially moved to the register or text memory 54. Also, when this is called up to display or print, the related information in Section 2 is removed and only the character information is displayed or printed.

When I enter a character string (sentence) for registration, is it a character? YES
Proceed to
The data are stored in order from the first digit of No. 2 and displayed sequentially on the display 94. After inputting one character string (sentence), RETUR
When you press the N key, the flag TR in Figure 10 is set to 1 this time, so the character string (text) in the line buffer 52 is
is registered in the text memory 54, enters the LBFSTR again, and the character information in FIG. 7 = RETURN? Proceed to YES with EIFPPT and the character string (text) will be printed.

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

When the MEMORY key is pressed at the end of character string (text) registration, a title name is registered in the text memory 54 in correspondence with the character string (text) registered this time, as shown in FIG. MEM
The ORY 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 and C0NTR0L keys so that the 5TORE lamp is not lit. MEMOR
Press the Y key. At this time, the MEMORY key lamp lights up to notify 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, for reference display, N0NPRT
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 at the time of registration. After this, the operator presses the ☆ key to perform reference display from a specific character string in the text, then inputs the specific character string, and presses the RETURN key. If you want to display the text as a reference 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 Φ key or the key, and at the same time the BACKSPAC
Deletion, insertion, etc. can be performed using the E key, H 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 CLR key is pressed
The PPT 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 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. The third type is the one that prints all the character strings (sentences) to be printed, and the third type is the character string (text) corresponding to the title name with a title name.
text) only 2 lines are printed. These instructions are entered after entering the title name: r/(N, r/1").

Just enter /2j 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, if you enter the ☆ key when registering a character string, you can pause printing at the corner of the column that has been printed up to that location. Alternatively, the operator can arbitrarily pause the printing by pressing the ☆- key during printing. To resume execution, press the ☆ key again. After printing a character string or sentence corresponding to a title name, if you want to print the same content again, simply press RET.
Just press the URN key. Also, if you press r/J, r2 directly without entering the third type title name, all 5D and record 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.

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 1 sentence registered in the sentence memory 54, etc., using the title master's power.

If the title master function is performed without pressing the N0NPPT key, the character string 9 sentences etc. will be printed on the printing paper of the printing device 41 for reference. Since the contents of the registered character strings 9 sentences etc. can be reproduced by these methods, it can be quickly determined whether or not they 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 a limited capacity, but if the entire text is printed out, it 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 input is performed, the process moves to the aforementioned line buffer processing routine LBFSTR, where 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.

By doing this, check whether there is an error in the title name selection of the character string (sentence) to be referenced, and if it is OK, RETtlR
Press the N key.

At this time, flag TR is checked. In the initial state, TR is reset to O, 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 flag 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,
Title name and text memory stored in ORK register 5
The MPU 44 compares the title names in 4. 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. Further, when a title name is displayed on the display 94, if the user wants to erase all the character strings (text) corresponding to the displayed title name, the DLR key is pressed. At this time, the CLR in Figure 12? Then, proceed to YES, and since the flag TR is set to 1 by pressing the RETURN key, proceed to YES when TR=17, and read the title name and character string (text) in the text memory 54 corresponding to the displayed title name. Clear everything.

Further, while a title name or a character string (sentence) is being referenced and displayed on the display 94, the displayed character string can be erased or corrected word by word by using the keypad or middle 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 RE T tl and RN keys are not pressed, TR=O, 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. 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 since it was set to 1 by the ☆ key, is TR=1? Proceeds to YES, and the flag SC is also set to l, so SC
= 1? -r YES The search character string stored in the line buffer 52 is saved to the WORK register and the display is continued. Since the flag NP is set to 1 by the N0NPPT key, the process advances to YES, and the following character strings (sentences) are displayed on the display 94 starting from the middle of the character string (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 a location matching the character string starting with rNEWJ from the beginning of the sentence), and displays the following character string (sentence) from there. This allows you to quickly reference the desired location. Continue the same string rN
If you want to display part way from another part starting with EWJ, press the ☆ key again and the flags TR = 1 and SC = 1, so go to YES for both, check the flag NP, and since it is 1, the character string (text) will be displayed. The following character strings (sentences) are displayed starting with the character string "Other rNEW". Further, the above can also be done using the printing device 41. N for that
Input the title name without pressing the 0NPPT 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. , RETtlRN
When the key is pressed, 77gTR=1, 5C=1, so the search character string is saved and displayed in the WORK register. At this time, the N0NPRT key is not pressed, so the flag N
If P=O, the process advances 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. During this printing, the search character string continues to be displayed on the display 94, so if a selection error is discovered, the printing can be stopped immediately.

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 entering the title name from the keyboard 10,
After pressing J, [0], press RETURNt-1. As in the previous example, the flag TR is initially 0, so proceed to NO, set the flag TR to 1, and then write the i title name to WOR.
Save to K register. Now, of course, the flag NP is not pressed, so proceed to NO, and after the title Meijinriki, r/
When the MPU 44 determines the information of J and rOJ, the character string (text) corresponding to the title name and all print-related information are sent from the text memory 54 to the line buffer 52 and printed on the printing paper without the title name. At this time, as mentioned above, information such as space, carriage return, print pitch, paper feed amount, etc. is stored in the text memory 5 along with character information when registering characters.
4, 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.

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, printing can be interrupted by pressing the intermediate key. 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 RETtlRN key the required number of times.

For type 2 and type 3 printing, input "/", "1", "/" and "2" after the title using the MPU 44 as in the previous example.
It is possible to detect and separate from the home, and selectively print the entire string of title names or only two lines. At this time, the title name continues to be displayed.

Also, in the case of the first and second types of printing, if the key is pressed at an appropriate delimiter during registration, subsequent printing will be automatically stopped once printing has been done up 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 9 and saves all the title names registered in the text memory 54 and their corresponding character strings (texts) 2 Since only the line is printed along with each title name, the current registration status can be quickly viewed and checked, which is extremely desirable. The amount of character strings (sentences) can be selected as appropriate using the number key next to the slash key "/".

As described above, according to the present invention, when a character string or text information is retrieved from a storage means that stores character strings or text information corresponding to title information, a format with or without title information is selected. Since the title information and the character string or text information can be printed using the printer, it is possible to very easily view and understand the character strings or text information stored in the storage means.
