Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character information processing apparatus for printing or transferring an input character string of one or more lines. For example, a tape printer in which a print medium is a tape or a stamp in which a transfer medium is stamped. It can be applied to a seal making device, which is a surface.

[0002]

2. Description of the Related Art In a conventional tape printing apparatus, keys for inputting characters and the like are arranged on an operation panel, and a desired character string can be input by operating these keys for inputting characters. In addition, the tape printing device is formed so that the tape can be sent out from the tape discharge port by driving the tape feeding mechanism, and the printing mechanism consisting of the thermal head and the tape cutting mechanism are sequentially arranged in the passage of this tape. It is designed to be done. When the print key is operated, the control means of the tape printer controls the tape feeding mechanism to feed the tape at a predetermined speed, and also controls the printing mechanism to input a character string previously input to the fed tape. To print. Further, even when the printing of the character string is finished, the control means of the tape printer continuously controls the tape feeding mechanism to feed the tape until the printed tape portion is outside the apparatus, and then the tape Stop running. After the user stops the tape running, the user operates the tape cutting mechanism to obtain a user-original label obtained by printing a desired character string.

[0003]

Even in such a tape printing apparatus, a desired character string can be input by the same input operation method as that of a character information processing apparatus such as a so-called word processor. However, since the tape printer is a compact device and has a small operation panel surface, and in addition to people who are familiar with character input by word processors, etc. in many cases, it is also possible to use the character string editing function. Has been made less.

For example, a moving function, a correction function, and a reconversion function are not provided. Here, the move function is a function of taking in a character string to be moved after pressing the move key, and then moving the character string to a designated destination position. The correction function is a function of automatically deleting a character string in a correction range designated after pressing the correction key and then automatically inserting a character string input until the correction key is pressed. The reconversion function is a function of returning a fixed character string designated after pressing the reconversion key to an unfixed character string.

Since there are few character string editing functions as described above, compensating operations for erroneous operations such as making an incorrect input position, selecting an incorrect character by Kana-Kanji conversion, or erroneously selecting hiragana have become complicated. . Moreover, the frequency of use of the delete function is considerably high in the compensation operation. For example, when moving a character string, the operation of deleting the original character string is performed, and when correcting the confirmed kanji to other kanji or hiragana, the operation of deleting the corrected character string is also performed. . This deletion function itself is also a function that must avoid erroneous operations. Since the tape printing device is required to be small and inexpensive, the display surface of the input character string is small, and as a result, in many conventional devices, the first character and the last character of the deleted character string are The delete function for specifying is not adopted, and a delete function for deleting one character by one operation of the delete key is provided. Therefore, when deleting a large number of characters in succession, it is necessary to repeat the operation of the delete key, and the number of times the delete key is operated may exceed the original number of times, resulting in deletion of unnecessary characters. obtain.

Further, as a function of deleting many characters at the same time (hereinafter referred to as erasing), a full-text erasing function of deleting all the character strings to be printed on the tape, a combination of the number of lines and a character size of each line, and a vertical length. A set of lines that is the unit for changing the style such as writing / horizontal writing (hereinafter called a paragraph)
And a paragraph erasing function for deleting all the character strings in. Due to the restrictions on the operation panel, in many tape printers, both of these erasing functions are assigned to the simultaneous operation of the key for deleting one character and the shift key, and are instructed by the menu selection on the display surface. ing. Therefore, there is a risk that the whole sentence or paragraph will be erased by mistake.

Such a problem similarly occurs not only in the tape printing apparatus but also in other character information processing apparatus having characteristics similar to those of the tape printing apparatus, such as a small number of editing functions.
For example, a resin in which the light receiving portion of ultraviolet rays is cured and the portion other than the cured portion is removed by the action of a predetermined fluid is used as a stamp marking surface, and the marking surface is irradiated with a light beam according to the input character string (this is a transfer operation. Even in the stamp creating apparatus in which the term of printing in the specification includes the transfer concept in some cases, there is a problem of erroneous operation at the time of inputting and editing a character string.

The present invention has been made in consideration of the above points, and many erroneous operations at the time of inputting and editing a character string can be compensated by a simple operation without complicating the operation panel surface. It is an object of the present invention to provide a character information processing device which has a good usability.

[0009]

To solve the above problems, the present invention comprises at least key input means, display means, storage means having various buffers and text areas, and character input edit control means. Capture input characters,
Further, the character information processing device for editing the fetched character string is characterized by the following.

That is, the key input means removes a processing instruction key for instructing a predetermined type of processing for removing a character string from a predetermined buffer or text area, and removing it from a predetermined buffer or text area by an instruction from the processing instruction key. The storage means includes a restoration buffer that stores a character string removed from a predetermined buffer or a text area, and the character input editing control means includes a processing instruction. When a predetermined type of processing command is given from the key input means by operating the key, the removed character string is stored in the recovery buffer, and when the character string is stored in the recovery buffer, operation of the recovery key When a revive command is given from the key input means, the character string stored in the revival buffer is restored to the specified buffer or text area. And characterized in that.

[0011]

In the character information processing apparatus of the present invention, the processing instruction key instructs a predetermined type of processing for removing a character string from a predetermined buffer or text area. When the above-mentioned predetermined type of processing instruction is given from the key input means by the operation of the processing instruction key, the character input editing control means stores the removed character string in the restoration buffer. The revival key instructs the revival of the character string removed from the above-mentioned predetermined buffer or text area by the instruction from the processing instruction key. With the string stored in the resurrection buffer,
When a revive command by operating the revival key is given from the key input means, the character input edit control means restores the character string stored in the restore buffer to a predetermined buffer or text area.

The input unit 10 is composed of a key input unit 11 having a push key, a dial key, etc., and a tape width detection sensor 12, although the detailed structure is omitted. The key input unit 11 generates character code data and various control data to be given to the control unit 20. The tape width detection sensor 12 detects the width of the loaded tape and provides the tape width information to the control unit 20. In practice, the tape is housed in a tape cartridge, and the tape cartridge is provided with a physical identification element such as a hole that defines the tape width. The tape width detection sensor 12 reads this physical identification element. Output tape width information.

In the case of this embodiment, the key input unit 11 has
For example, a dedicated key for instructing a restoration function described later is provided.

The output unit 30 has a print configuration and a display configuration. For example, the tape / ribbon feed motor 31, which is a stepping motor, feeds the loaded tape or ink ribbon (not shown) to a predetermined printing position or the outside of the apparatus. The thermal head 32 prints on a running tape by thermal transfer.
Up to 128 dots can be printed at the same time. These tape / ribbon feed motor 31 and thermal head 3
2 are driven by a motor drive circuit 33 and a head drive circuit 34, respectively, under the control of the control unit 20. Cutting of the printed tape is performed by, for example, an external force from a user or a cutter (not shown) driven by a motor (not shown).

In the case of the tape printer according to this embodiment,
A liquid crystal display 35 is provided as a display unit,
The liquid crystal display 35 is driven by a display drive circuit 36 under the control of the control unit 20, and directly displays an input character string, various attribute information, and the like, and displays the attributes written around the liquid crystal display 35 of the apparatus body. An indicator that indicates whether the attribute corresponding to the character string shown is on or off is turned on.

The control unit 20 is composed of, for example, a microcomputer, and has a CPU 21, a ROM 22,
RAM23, character generator ROM (CG-R
An OM) 24, an input interface 25, and an output interface 26 are connected via a system bus 27.

The ROM 22 stores various processing programs and fixed data such as kana-kanji conversion dictionary data. The RAM 23 is used as a working memory and also stores fixed data related to user input. The RAM 23 is backed up even when the power is turned off.

The processing programs and fixed data stored in the ROM 22 and the data stored in the RAM 23 will be described in detail later. The ROM 22
Stores a processing program 22a for inputting and editing characters, and a working area (print buffer, display buffer, etc.) for that purpose is appropriately formed in the RAM 23 when the program 22a is executed, or is formed in advance. Used.

The CG-ROM 24 stores font information of characters and symbols prepared in the tape printer, and the characters and symbols (hereinafter, simply referred to as characters).
When the code data for specifying (hereinafter, the code may be omitted and referred to as a character) is given, the corresponding font information is output. Where CG
The font information stored in the ROM 24 may be an outline font or a bitmap font.

The input interface 25 serves as an interface between the input section 10 and the control section 20.
The output interface 26 includes the output unit 30 and the control unit 20.
The interface between them.

The CPU 21 uses the RAM 23 as a working area for the processing program in the ROM 22 which is determined according to the input signal from the input unit 10 and the processing stage at that time, and also, if necessary, the ROM 22 and the RAM 2.
The fixed data stored in No. 3 is used as appropriate for processing, and the processing status and processing result are displayed on the liquid crystal display 35 or printed on a tape (not shown).

(B) Buffer Functioning at Character Input and Editing Next, a configuration example of a buffer functioning at the time of character string inputting and editing will be described in detail with reference to FIG. It should be noted that character string input using the buffer and processing at the time of editing (particularly processing related to the restoration function) will be described later.

When inputting or editing a character string, the input character buffer 23a, the converted character buffer 23b, as shown in FIG.
The restoration buffer 23c, the text area 23d, and the display buffer 23e function. Furthermore, the input code register provided in the input interface 25 or the CPU 21 also functions at the time of character string input and editing. It is determined whether the code stored in the register is a character code or a control code. If the code is a character code, it is appropriately processed and transferred to the input character buffer 23a.

The input character buffer 23a stores an entry word (herein referred to as hiragana) of a character string for which a hiragana confirmation, katakana confirmation, or kana-kanji conversion confirmation has not been performed when a character code is input. For example, the consonant alphabet in the Roman character input mode is also stored here.

The converted character buffer 23b stores a character string temporarily stored as hiragana or katakana for the character string stored in the input character buffer 23a and a kanji candidate at that time in kana-kanji conversion. . In the device of this embodiment, even if the hiragana and katakana are confirmed, the hiragana and katakana can be converted to each other before the next character is input or the cursor is moved. This is done (see FIG. 1 (E)), and hiragana or katakana confirmation in such a state is called temporary confirmation as described above.

The text area 23d is a portion for storing all input fixed character strings (in the following description, temporary fixed character strings are not stored in the text area 23d). A code for clarifying whether or not it is also stored.

The display buffer 23e is used to display positively the fixed character string stored in the text area 23d and the temporary fixed character string stored in the converted character buffer 23b around the cursor, and to input The unconfirmed character string stored in the character buffer 23a to which the conversion instruction is not given is displayed negatively, and further, the consonant alphabet in the Roman character input mode stored in the input character buffer 23a and the converted character buffer 23 are stored.
The kanji candidates or the like stored in b are stored so as to blink.

In the case of this embodiment, in addition to the buffer group existing in the above conventional apparatus, the restoration buffer 23c is also provided.
Have.

The revival buffer 23c stores a character string erased from the text area 23d, the input character buffer 23a, etc. by a predetermined process described later, and causes the revival buffer 23c to store the character string. The revival reason parameter 23cP representing the predetermined processing is also stored. As described above, when the key newly instructed to be restored in this embodiment is operated in the key input unit 11, the characters or characters stored in the restoration buffer 23c are displayed in a manner according to the restoration reason parameter 23cP. The character string is restored to the text area 23d, the input character buffer 23a, or the like.

(C) Restoring Function Related Processing at Character Input and Editing Next, processing related to the character string recovering function at the time of character input and editing will be described with reference to the schematic processing flowchart shown in FIG.

As a process related to the character string restoration function, broadly speaking, the process of saving the character string in the restoration buffer 23c (FIGS. 1A to 1F) and the character string from the restoration buffer 23c are performed. There are two types of processing (FIG. 1 (G)) for taking out the data. First, the former processing will be described.

When the character deletion command is recognized while the cursor is positioned at the confirmed character, the CPU 21 causes the CPU 21 of FIG.
In step 100 of the subroutine shown in (A), the character is stored in the latest character position of the recovery buffer 23c and the recovery reason parameter 23cP is "deleted".
In step 101, the text area 23d
The character is deleted from, and the display buffer 23e is updated accordingly, and the display content on the liquid crystal display 35 is also updated, and the process returns to the main routine. The character deletion in this embodiment is similar to what is called "backward" in so-called word processors and the like.

When an undetermined character string (Hiragana or Katakana) is stored in the converted character buffer 23b and a character deletion command is given while the cursor is positioned at the undetermined character string, the CPU 21 causes the converted character string to be converted. Character buffer 23
The undetermined character string stored in b is added to the text area 23d as a confirmed character string, and the converted character buffer 23b is added.
After clearing, the above-mentioned processing of step 101 and thereafter is performed. On the other hand, at the time of deleting the unconfirmed character, although not shown, the saving to the restoration buffer 23c is not executed.

As is apparent from FIG. 1A, in this embodiment, when the characters are deleted successively, the plurality of characters are continuously stored in the restoration buffer 23c. ing. In this case, the recovery reason parameter 23cP may be added to each character, or one recovery reason parameter 23cP may be added as a whole.

Further, what is saved in the restoration buffer 23c is not limited to characters (or symbols), but may be a line head mark or the like indicating a line number. In this case, in the processing of step 101, two lines or two paragraphs are appropriately connected. Also, at the time of revival, line feed processing and paragraph break processing will be performed.

When the cursor movement command is recognized, the CPU
21 proceeds to the subroutine shown in FIG. 1B, and in step 110, operates the display buffer 23e in accordance with the command to move the position of the cursor on the liquid crystal display 35 (the character string portion to be displayed if necessary). ) Is updated and displayed, and the process returns to the main routine. The cursor movement key is also used to switch candidates for various menus, but FIG.
Indicates only the case of the cursor movement command. If an undetermined character string (Hiragana or Katakana) is stored in the converted character buffer 23b and a cursor movement command is given when the cursor is positioned on the undetermined character string, CP
U21 adds the unconfirmed character string stored in the converted character buffer 23b to the text area 23d as a confirmed character string, clears the converted character buffer 23b, and then performs the processing from step 110 described above.

The cursor movement processing shown in FIG. 1B has been explained here because the restoration buffer 23c is not cleared by the deletion instruction or the cursor movement immediately after the all-text erasing or paragraph erasing instruction described later. This is because I want to explain. That is, even if a cursor movement operation is performed immediately after a delete command for saving a character string in the revival buffer 23c or an operation for erasing an entire sentence or a paragraph erasing command described later, the revival buffer 23c is not cleared. When a character string is saved in the revival buffer 23c in response to a non-conversion, katakana conversion, or Chinese character confirmation operation, which will be described later, the revival buffer 23c is cleared immediately after the cursor movement operation is performed (FIG. 1). (See (H)).

When the command for erasing the whole sentence is recognized, the CPU 21
Goes to the subroutine shown in FIG.
20, all character strings (including codes designating lines and paragraphs) in the text area 23d are restored in the buffer 2
In step 121, the character string is deleted from the text area 23d and the display buffer 23e is updated to the contents for the initial character input screen accordingly. The display contents on the liquid crystal display 35 are also updated and the process returns to the main routine.

When the paragraph erasing command is recognized, the CPU 21
Goes to the subroutine shown in FIG.
30, all the character strings (including the code designating the line) of the paragraph in which the cursor is located in the text area 23d are stored in the restoration buffer 23c, and the restoration reason parameter 23cP is set to “Delete paragraph (including paragraph number)”. In step 131, the character strings are deleted from the text area 23d, and the display buffer 23e is deleted.
Is also updated accordingly, the display content on the liquid crystal display 35 is changed, and the process returns to the main routine.

In the case of this embodiment, when the delete key is operated, the candidate characters "delete all text" and "paragraph delete" are displayed on the menu, and when "delete all text" is displayed as a candidate, the selection key is pressed. When operated, the CPU 21
Recognizes that it is a command to erase all sentences, and when the selection key is operated while "Erase paragraph" is displayed as a candidate, C
The PU 21 recognizes this as a paragraph erasing command.

When a command to erase all sentences or paragraphs is issued, the restoration buffer 23c is cleared by the processing shown in FIG.

The processing for saving the character string in the text area 23d in the restoration buffer 23c has been described above. However, in the following, the character string (Hiragana for input heading) in the input character buffer 23a is stored in the restoration buffer 23c. The saving process will be described.

When a valid non-conversion command is recognized, the CPU 2
1 proceeds to the subroutine shown in FIG. 1 (E), and in step 140, it is determined whether it is provisionally determined as hiragana or katakana or not determined based on whether or not there is a character string in the input character buffer 23a. Determine. If it is undetermined, the CPU 21 determines in step 141 that
The character string in the input character buffer 23a is restored to the buffer 2
It is stored in 3a and the revival reason parameter 23cP is set to "no conversion". Next, at step 142, the Hiragana notation of the input character buffer 23a is stored in the converted character buffer 23b as a temporarily fixed character, and the display buffer 23e is operated to also operate the temporarily fixed character on the liquid crystal display 3.
5, the input character buffer 23a is cleared in step 143, and the process returns to the main routine. on the other hand,
When the CPU 21 obtains the result of the provisional confirmation by the determination performed after the recognition of the non-conversion command, the CPU 21 performs the Hiragana / Katakana conversion of the provisionally determined characters stored in the conversion character buffer 23b in step 144, that is, hiragana. If is stored, it is converted to katakana, and if katakana is stored, it is converted to hiragana, and in accordance with this, the display buffer 23e is operated and the temporarily fixed character displayed on the liquid crystal display 35 is also changed between hiragana / katakana. Convert.

Although not shown in the figure, the CPU 21 also performs the same processing when recognizing a valid katakana conversion command. The difference from the case of no conversion command is that when an unfixed character string is first stored in the converted character buffer 23b as a temporarily fixed character string (step 142), it is stored in katakana.

Therefore, when the non-conversion command and / or the katakana command continue, the temporarily fixed characters continuously change to hiragana, katakana, hiragana, katakana, .... When a command other than this is issued, the temporarily fixed character is stored in the text area 23d as a fixed character and the converted character buffer 23b is cleared (see FIG. 1 (H), step 171).

When the confirmation command for kanji conversion is recognized, the CPU
21 proceeds to the subroutine shown in FIG. 1 (F) and, in step 150, stores the confirmed kanji character string (including the hiragana selected by the kanji conversion operation) stored in the converted character buffer 23b in the restoration buffer 23c. At the same time, the revival reason parameter 23cP is set to “Kanji conversion”. Next, in step 151, the conversion character buffer 23b
The kanji strings related to the confirmation stored in the text area 2
In step 152, the input character buffer 23a and the converted character buffer 23b are cleared and the process returns to the main routine.

Next, the processing when the restoration command is given will be briefly described. Details will be described later with reference to FIG.

When the key instructing the revival function is operated and the revival command given is recognized, the CPU 21 causes the CPU 21 of FIG.
The process proceeds to the subroutine shown in (G), the content of the resurrection reason parameter 23cP is discriminated in step 160, and in step 161, the restoration process according to the discriminated restoration reason is performed, and the process returns to the main routine.

When a command relating to a character input / editing function other than that described above is recognized, the CPU 21 causes the CPU 21 of FIG.
As shown in (H), in step 170, if there is a character string in the restoration buffer 23d, it is cleared, and in step 17
At 1, the process according to the command is executed and the process returns to the main routine.

Next, the process at the time of restoration shown in FIG. 1G will be described in detail with reference to the detailed flowchart of FIG.

When it is determined that the character string is not stored in the recovery buffer 23c as a result of the determination of the recovery reason parameter, the CPU 21 operates the display buffer 23e in step 200 to display a warning indicating that there is no recovery target. After that, it returns to the character input screen when the revival command is issued and returns to the main routine.

When the revival reason parameter indicates the deletion, in step 210, the CPU 21 moves the one character stored most recently in the revival buffer 23c to a predetermined position defined by the cursor of the character string in the text area 23d. Add (copy) and display buffer 23e accordingly
Is also operated to change the display on the liquid crystal display 35, and thereafter, in step 211, the one character most recently stored in the restoration buffer 23c is deleted. Then, it is determined whether or not the characters in the resurrection buffer 23c have disappeared by such deletion, and if they exist, the resurrection reason parameter 23cP is changed to "no character string" immediately, and then the process returns to the main routine.

As is clear from the above processing, the restoration position may be different from the deletion position, so that the user
A character string can be moved by combining the delete and restore functions.

When the revival reason parameter instructs to erase the whole sentence, the CPU 21 adds all the character strings stored in the revival buffer 23c in the text area 23d in step 220 regardless of the position of the cursor. (Copies), and accordingly, the display buffer 23e is also operated to change the display on the liquid crystal display 35, and thereafter, in step 221, the recovery buffer 23c is cleared and the recovery reason parameter 23cP is set to a character string without any character string. Change and return to the main routine.

When the revival reason parameter indicates the paragraph deletion, the CPU 21 includes all the character strings stored in the revival buffer 23c in the revival reason parameter in step 230 regardless of the cursor position. Is added (copied) in the text area 23d at the paragraph number position, and the display buffer 23e is also operated accordingly to change the display on the liquid crystal display 35. Then, in step 221, the restoration buffer 23c is changed. At the same time as clearing, the revival reason parameter 23cP is changed to no character string and the process returns to the main routine.

When the revival reason parameter indicates a conversion relationship such as no conversion or Kanji conversion, the CPU 21 copies all the character strings stored in the revival buffer 23c to the input character buffer 23a in step 240. Also, the corresponding kanji is deleted from the text area only in the case of kanji conversion, and in response to this, the display buffer 23e is also operated to accept no conversion, katakana conversion, or conversion (kanji conversion) of the display on the liquid crystal display 35. The display state is changed to the initial display state, and then, in step 221, the restoration buffer 23c is cleared and the restoration reason parameter 23c is set.
Change P to no character string and return to the main routine.

FIG. 5 is an explanatory diagram showing a user's operation and a display surface change related thereto. In FIG. 5, a quadrangle represents a display surface, a solid line with an upper side represents the entire display surface, and a dashed line with an upper side represents only a display surface area for character input and editing.

In the situation where "ai" is confirmed and input (see FIG.
(A)), when a deletion command is given, one of the menu screens including both full-text deletion and paragraph deletion is displayed as a current selection candidate (FIG. 5 (B)). If the select key is operated when the whole text deletion is displayed as a selection candidate at the present time, all the lights are turned off to let the user know that the whole text deletion has been executed, and then the display is displayed on the initial character input screen. Return (FIGS. 5C and 5D). At this time,
“Ai” is stored in the resurrection buffer 23c, and “all text deletion” is stored as the resurrection reason parameter 23cP. After that, when the revival key is operated without any other operation, the character string "ai" in which the whole sentence is erased is revived and displayed (FIG. 5 (E)).

When the delete key is operated while the cursor is positioned at "i", "i" is erased and only "a" is displayed (FIG. 5 (F)). At this time, “I” is stored in the recovery buffer 23c, and the recovery reason parameter becomes “delete”. After that, when the revival key is operated without any other operation, the deleted character "i" is revived and displayed at the position defined by the cursor (FIG. 5 (G)). At this time, the revival buffer 23c is cleared.

When the revival key is operated in such a situation, since the revival target is not in the revival buffer 23c, a warning (for example, blinking of the input display surface) is given and the original character input screen is returned (FIG. 5 (H) and (I)).

(D) Effect of Embodiment According to the above embodiment, when a revival buffer and a revival key are provided and a character string is deleted or deleted from the text area or the character input buffer by a predetermined process, the character string is deleted. After storing it in the resurrection buffer and performing such an operation,
Basically, when the revive key is operated immediately, the character string in the revival buffer is revived, so many erroneous operations at the time of entering and editing the character string are easy without complicating the operation panel surface. It is possible to realize a character information processing device which is easy to use and can be compensated for by various operations.

Further, according to the above embodiment, the restoration position for character deletion may be different from the deletion position, so that it can be used as a moving function.

In the case of Kanji conversion, when a command for converting Hiragana as an input headword to Kanji is issued and Kanji candidates are displayed, the conventional method is also used.
With the cancel key, you can return to hiragana as a headword, but when you confirm a kanji, the headword disappears from the input character buffer and the cancel key cannot handle it.
The resurrection function is effective in this respect.

There is also a word processor having a function of re-converting a fixed kanji into an unfixed hiragana. In this case, however, a process of reversely accessing the kana-kanji conversion table using the fixed kanji as a keyword is required. Moreover, the processing time and processing load are large, and therefore the above-described embodiment is useful.

(E) Other Examples Although the other examples of the present invention have been described above, the following other examples can be given.

In the above embodiment, the present invention is applied to the tape printer, but it can be applied to other character information processing devices which require the display of the character input screen. For example, it can be applied to a simple word processor or a seal making device.

In the above-mentioned embodiment, the case where the revival due to the character deletion is designated character by character is shown, but all the deleted character strings stored in the revival buffer are revivald by one revival instruction. May be. Further, in this case, the process may be such that the revival buffer is not cleared even if it is revitalized, or the revival buffer is not cleared by the cursor movement key, and the same character string may be revitalized again at other places ( Multiple copy function).

The present invention can also be applied to a character information processing apparatus that deletes character strings by designating the first and last characters of the deleted character string.

Further, in the above-mentioned embodiment, as the restoration function from the deletion and deletion, the one in which the restoration buffer is cleared by the key operation other than the delete key and the cursor movement key is shown, but the key input which does not clear the restoration buffer is shown. You may make more kinds.

Needless to say, the objects to be restored are not limited to those in the above embodiment. For example, in the above-mentioned embodiment, the unrestored character cannot be restored in regard to the restoration function from deletion and deletion, but these restorations may be possible. Furthermore, the revival immediately after the symbol selection is confirmed may be permitted.

In the above embodiment, the device for the Japanese character string is shown, but it is needless to say that it can be applied to the device for handling characters of other languages. For example, in the case of a device for Western characters, there is no character type conversion function, but there is a deletion or deletion function, so the same can be applied.

The number of revival keys is not necessarily limited to one, and there may be two or more types.
