Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an input/output device that can arbitrarily call up a fixed phrase registered in a fixed phrase memory.

The function of inputting and outputting character strings electronically is essential for the desired operation of electronic typewriters, so-called word processors, various computers, and the like. In such a character string input/output device, a Japanese document containing Kanji is created by normal typewriting and, in some cases, Kana-Kanji conversion, Roman character conversion, etc.

It is well known that in order to improve input/output efficiency in this case, a method is adopted in which fixed phrases are registered in advance and called up and used as needed. When registering or recalling such a fixed phrase, it is convenient to determine whether or not an underline has been added, and if the underline addition mode is selected, to print or store it accordingly.

Conventional technology When recalling and printing registered fixed phrases or newly registering fixed phrases in a user dictionary, even if an underline is added to the target fixed phrase, the underlined data is treated as normal character data. were treated separately.

Problem to be Solved by the Invention However, when registering a fixed phrase or reading a registered fixed phrase and using it as part of a created character string, it is more convenient to register or read out underline information at the same time. is often good. This is because once a fixed phrase is registered with an underline added, it is often used again with an underline added.

OBJECTS OF THE INVENTION It is an object of the present invention to improve the handling of formulaic phrases by adding underlines and to provide an input device that is easy to use.

Means for Solving the Problems of Structure of the Invention The object of the present invention is to provide an input/output device having the structure described in the claims, that is, a means for setting and canceling the underline addition mode, and an apparatus for setting and canceling the underline addition mode. A mode storage means for storing settings, a buffer memory for storing key-input character data, and when storing the contents of the buffer memory in the fixed phrase memory, reading data one by one from the buffer memory and adding an underline to it. When the mode is set, this is achieved by an input/output device including a control means for adding underline information to the read character data and storing it in the fixed phrase memory.

According to the input/output device according to the present invention, when registering a fixed phrase, whether or not an underline is added is checked and stored each time, and furthermore, when registered fixed phrases are added one after another, they are displayed as they are depending on the underline addition state. An input/output device capable of printing is obtained.

Example Hereinafter, the configuration of the present invention will be explained in detail with reference to the accompanying drawings.

In this embodiment, a Japanese input/output device is disclosed as an example, but it is of course applicable to a Roman input/output device (word processor).

FIG. 1 is a perspective view showing the appearance of a Japanese electronic typewriter, which is an example of an input/output device according to the present invention. This Japanese electronic typewriter 1 is broadly divided into a printer section 10 and a keyboard section 20. The printer section 10 is
As is well known in the art, the printer has a carriage 12 that moves along a guide rod 11, and a print head 13 carried by the carriage. This print head 1
3 can be a thermal head, for example, and can print with low power consumption on the thermal paper 15 placed on the platen 14 or on plain paper using a thermal transfer ribbon. Other printheads may also be used depending on conditions. In addition, a print section cover 16 is provided, which functions as a cover for convenient carrying of the book and also as a cover during use, as well as a release lever 17 and a power switch 1.

The keyboard section 20 has an elongated display 21, and as shown in Figure 3 of the Ryuteki 3, the keyboard section 20 has character keys and symbol keys used in ordinary quiwriters, as well as function switching keys specific to this device. Due to the demand for miniaturization of devices, this display is preferably a liquid crystal display (LCD), which is a small display that partially displays one printed line and can display images with low power consumption. However, other displays are also possible.

FIG. 2 shows an example of the functions of the input/output device according to the present invention. In addition to basic functions such as input, editing, printing, and display,
It has the ability to connect to an external storage device and communicate between devices of the same model via an appropriate interface. In addition, it has a user dictionary that allows users to register their own fixed phrases and words, as well as a learning function that prioritizes output of recently used characters and words, and saves power when not in use for long periods of time. It is equipped with automatic power saving functions, etc.

FIG. 3 shows an example of the structure of the upper part of the keyboard of the input/output device according to the present invention. It is equipped with the character keys, symbol keys, function keys, and operation keys necessary to perform its functions. When a character/symbol key 22 surrounded by a two-dot chain line is pressed alone, the respective character/symbol is input to the device in the selected mode. new line·
The execution key 23 is used to instruct line breaks during key input and edit/
This is a key that instructs execution of connection/communication with an external storage device, etc. The character type selection key 24 allows input characters to be alphanumeric or
You can choose between katakana and hiragana. The space key 25 is used to input a space (blank). The characters input in this manner are displayed on the display 21 as inverted white characters on a black background.

The no-conversion key 26 is pressed when the user wants to confirm the displayed kana characters without converting them. As a result of this confirmation, the display on the display 21 changes to a normal display of white characters and black characters. On the other hand, the conversion key 27 is pressed when converting kana characters displayed on the display 21 into kanji characters. If there are many candidate kanji and they cannot all be displayed at once, press the conversion key 27
By pressing , the next candidate kanji will be displayed. In this case, if the user wishes to return to the previous display because the display has gone too far, by pressing the previous candidate key 25, the previously displayed character/word can be returned to the previously displayed candidate kanji.

By pressing the shift key 29 on the left and right at the same time as the above-mentioned character/symbol key -22, the character/symbol marked on the upper side of the key, for example, when Katakana mode or Hiragana mode is selected, kana lowercase letters can be changed. You can also enter other characters/symbols. If the alphanumeric mode is selected, lowercase letters are normally input, but uppercase letters can be input by pressing the shift key 29 at the same time. Furthermore, the shift lock key 30 eliminates the need to constantly press the key when continuing the operation of the shift key, and indicates that the key has been pressed by lighting an LED. This state is canceled by pressing the shift key 29, and the LED is also turned off.

It is possible to perform various functions such as displaying the remaining amount of memory, displaying a list of user registrations, and displaying the beginning or end of a line by pressing the left and right cursor keys at the same time.

The registration key 34 is used to perform user registration. A character string such as a sentence or phrase that is displayed and selected with the cursor key is registered as a user dictionary in response to pressing the registration key 34 again.

The symbol key 35 is used to display a predetermined number of special symbols that do not appear on the keyboard and to select and input a desired symbol.

The key 36 is a key for inputting Roman characters, and when pressed, the LED at the upper left side lights up. The key 37 is a key for instructing full text printing, and the key 38 is a key for setting a print range. The key 39 is a key for setting or canceling a tab, and the key 40 is a repeat key for repeating the same input. Keys 41 to 47 are a group of keys for instructing the functions described above. 6 Further, keys 48 and 49 are paper feed keys, which are keys for moving the paper forward or backward, respectively.

Key 50 is a deletion key, and key 51 is a cancellation/cancellation key. Further, the key 52 is a key for inputting a semi-voiced sound, and the key 53 is a key for inputting a voiced consonant, and by pressing the corresponding key subsequently, it is possible to input a semi-voiced consonant or a voiced consonant.

11, an underline information setting program 612 and a fixed phrase setting program 613 are provided. In addition, the writable memory 62 includes a display buffer 621 and a fixed phrase memory 6.
22 and underline addition mode storage register 62
3. In this configuration, character strings are input by predetermined operations from the keyboard 20 as described above. Furthermore, in order to improve the efficiency of inputting character strings, the writable memory 62 is used to register fixed phrases of about several dozen characters, which can be recalled and inputted as needed. The fixed phrases registered in this way can be used within the necessary range and can be deleted or updated as appropriate.

The main operations and associated operations of the input/output device according to the present invention will be disclosed below with reference to the keyboard of FIG. 3.

To enter alphanumeric or katakana characters, use the respective selection keys 24.
After pressing the button to enter each mode, input can be made using the character keys 22. This content is displayed on the display 21, and document creation, printing, storage, updating, etc. are performed. If necessary, by switching the character size selection key 41, for example, if the number of dots in a full-width character in the horizontal direction is 24 dots, half-width and half-width characters, which are half the number of 12 dots and double the number of 48 dots, can be changed.
You can also select either double angle. Note that half-width characters are valid only for some alphanumeric characters and special symbols.

To enter hiragana, press the hiragana selection key 24 (or the romanization selection key 36), then press the character key 2.
Press 2. Hiragana characters input in this way are displayed in reverse video on the display 21. If this display is correct and does not require conversion, the no-conversion key 26 is pressed to confirm the normal display. To enter kanji,
After inputting the reading of the desired kanji in the hiragana mode or romaji mode, the conversion key 27 is pressed.

Along with this, candidate kanji or compound words are displayed on the display 21, and the desired kanji or compound word can be determined by using the corresponding number keys. If there are a large number of candidate characters, you can return to the previous display by pressing the conversion key 27 again, or if you have gone too far and want to return to the previous candidate character group, you can use the previous candidate key 28 to return to the previous display. This kanji conversion converts to normal display.

Regarding the user dictionary, there are various operations such as registration, recall, deletion, list display, and list printing.

For user dictionary registration, when the registration key 34 is pressed, the display 21 becomes a user registration input screen, and a desired character string is entered using the keys. Next, the character string is displayed in reverse by moving the cursor. The length of the registered word in this example is:
It is 40 characters. If you need to add an underline to the desired part or part of the registered word you are trying to register, place the cursor at the beginning of the relevant part and press the "Function key" and the letter key "Na" (the number key "6") at the same time to set the underline additional information. This corresponds to inserting an underline start code before the cursor position and setting the underline addition mode storage register 623 in the underline mode setting program 612 of FIG. Next, by operating the cursor keys, move the cursor to the last position where the underline will be added, and press the "m function key" and the letter key "na" at the same time again to cancel the underline addition mode. can. At this time, the underline end code is inserted after the cursor position, and the underline addition mode storage register 623 that was previously written is reset. Instructions for erasing underlines can be obtained by pressing the "Function key" and the letter key "Ni" (
By pressing the number key "7" at the same time, the underline of the desired portion can be erased. Next, when the registration key 34 is pressed again, a registration reading input screen appears. Here, enter the appropriate hiragana pronunciation, that is, the registered name. In this example, the maximum number of characters for one registration is 1.
There are 0 characters. After completing the preparation, the user presses the registration key 34 to complete the registration of the desired user registration word.

During this process, if the number of characters or other values are outside the limited range, a buzzer will notify the user.

Calling up the fixed formats registered in this way is carried out in the same way as normal kana-kanji conversion after keying in the registered pronunciation. If underline information is added to this registered standard format, it is directly output to the display buffer and displayed, and is printed as is according to an instruction.

The registered readings of standard orientations and the list of standard orientations can be displayed by simultaneously pressing the function key 3 '3 and a specific character key, in this example, the character key "U" (corresponding to the number key "3"). Is displayed. In this case, the display 21 displays the following message: ``User dictionary list 1. List display 2. List print''. Then number key "1" (letter key "A")
), a user dictionary list display mode is obtained, and the user-registered standard pronunciation and the first ranked registered word are displayed. Here, if the down cursor key is pressed alone, the registration display of the subsequent rankings is displayed, and readings and registered words can be displayed in order. In this case, the display is performed in a predetermined order, in this embodiment, in the alphabetical order of the pronunciations of the registered words. Note that such an order may be registered while taking into account the order of pronunciation at the registration stage, or the registration may be performed according to the available space in the dictionary and the pronunciation order of the registered words may be set at the stage of list display or list printing. Also, press the up cursor key △
You can return to the previous display. Further, in response to pressing the left/right cursor keys, the display is scrolled one character at a time to the left and right. On the other hand, when either the function key 33 or the cursor key 32 is pressed simultaneously, the following operation occurs.

When function key 33 and up cursor key △ are pressed at the same time,
Display the first user registration word. When the function key 33 and the down cursor key are pressed simultaneously, the remaining amount of the user dictionary registration area is displayed. As a result, the possibility of new user registration can be confirmed. Further, when the function key 33 and the left/right cursor key <> are pressed simultaneously, the first character or last character of the user registered word related to the display is displayed.

Also, press the number key "2" (letter key "i") in the display "User dictionary list 1. List display 2. List printing" obtained by pressing the function key 33 and the letter key "U" at the same time. As a result, the user dictionary list printing mode is obtained, and the readings and user registered words are printed in alphabetical order. As a result, it is possible to read the registered name and confirm the entire user registered word not only on the display but also on the printed paper.

To delete a user registered word when it is no longer needed, see (7) above.
In the dictionary list display mode, display the user registered words to be deleted using the up and down cursor keys, and then press 81
This can be executed by pressing the Tg key 33 and the delete key 50 at the same time.

Note that if the user registered word displayed at the end of the list is deleted, the remaining capacity of the user dictionary is displayed.

The handling of underline information when registering a user dictionary will be disclosed below with reference to the flowcharts of FIGS. 5 and 6.

When the flow of standard orientation registration shown in Figure 5 starts, step 1
The first character to be registered is extracted from the display buffer that stores the character string to be registered, such as 01.

If a function code other than the character code is retrieved here, it is processed in another control routine, and when the underline start code is retrieved, the underline addition mode is set and the underline end code is retrieved. When this happens, the underline addition mode is canceled. This character is set in the standard dictionary as in step 102. Next, in step 103, the underline addition mode storage register is read, and it is determined whether or not the underline addition mode is set. If this judgment is YES, in the subsequent step 104, underline information is also set in the fixed phrase dictionary, and in step 10
5. This underline information can be added by using specific bits of the character code as underline information bits. On the other hand, this judgment is
If O, step 104 is skipped and step 105 is reached directly. Here, it is determined whether or not the last character to be registered has been registered, and if this determination is No, step 1
Return to 01 and repeat the above operation.

On the other hand, if this determination is YES, this means that the registration operation has already been completed, and this flow ends.

When the fixed phrase call flow in Figure 6 starts, Step 1
10, the first character of the fixed phrase that is instructed to be recalled is retrieved from the fixed phrase dictionary.

Next, in step 111, the underline information bit is looked at, and the underline information is referenced.
If it is underline additional information, the underline addition mode is set, and if it is not underline additional information, the underline addition mode is canceled. The result is determined in step 112. If the determination in step 112 is YES, an underline code is added to the character code as in step 113. The character code including the underline code is then set in the display buffer as in step 114.

If the determination in step 112 is NO, step 11
Step 3 is skipped and step 114 is reached.

Thereafter, in step 115, it is determined whether the last character has been completed. This judgment is N.

In this case, the process returns to step 110 and the above-described operations are repeated.

If this determination is YES, it means that there are no more characters to call, so this flow ends.

Effects of the Invention According to the input/output device according to the present invention, when registering or recalling a fixed phrase in a user dictionary, an operation is performed that also takes into account underline information, so that the usability of the device is improved.
