Description

Description: TECHNICAL FIELD The present invention relates to a character data processing apparatus for inputting character data such as text and arbitrarily specifying a printing magnification for printing on recording paper.

[Prior art and its problems] In general, a word processor is often used as a device for creating a text or the like and printing it on a recording paper to obtain a document.
The word processor converts desired key-input document data into kana / kanji characters, temporarily writes the converted data into a memory, and reads and prints the data stored in the memory to obtain a desired document. This type of word processor can usually specify a print magnification such as double-width or half-width for individual character data in an input document.
In particular, on a display unit having a small display area, it is impossible to display and output character data having a size corresponding to the designated print magnification at all magnifications. Therefore, for example, the character data for which the print magnification is specified is displayed with a mark for identifying the specified magnification.

The one line means 1/24 line of one character.

Here, in the encoder 44, when the encoder pulse is received in the order of the photo sensor 43a → 43b in FIG. 2 due to the normal rotation of the encoder disk 41, the encoder pulse received by the photo sensor 43a is output, When the encoder pulse is received in the order of the photosensors 43b → 43a due to the reverse rotation of the encoder disk 41, the encoder pulse is not output. That is, when the encoder disk 41 rotates in the reverse direction, the thermal head 27 is not driven even when the print mode PR is set.

On the other hand, a printing magnification image character generator 60 is connected to the display character generator 58 in parallel. The print magnification image character generator 60 displays an image character having a print magnification corresponding to each display character in accordance with print control data read together with the character code of each character data from the text data storage unit 56.
In this case, an image pattern P corresponding to the character magnification is displayed on the display unit 13 together with each character data of the created document data.

FIG. 4 shows the character code of each character data stored in the text data storage section 56 and the storage state of the print control data. The print control data indicating the preset print magnification is stored in 2 bytes. 1 byte at the beginning of each character code
Is set by

Figure 5 shows the print magnification image character generator 60
, Indicates an image pattern obtained in accordance with the print magnification indicated by the print control data of each character data, and each image pattern is given as a pattern that images the size, shape, etc. of the corresponding print magnification.

Next, the operation of the character data printing apparatus having the above configuration will be described.

First, to create a desired document, the user operates the mode changeover switch 11 to specify the word processing mode WP. Then
The control unit 51 is set to the word processing mode WP. here,
The user operates the key input unit 12 of the apparatus main body 10 to sequentially input desired characters, symbols, and the like.

First, when the user inputs a document information to be created by operating the character / symbol input key 14 and the function key 15, the input document data is sequentially transferred to the conversion data storage unit 52 addressed by the control unit 51. You. At the same time, the input document data is input to the display character generator 58 and the display character generator 58.
It is displayed on the display unit 13 via the RAM 53. And
When the Kana / Kanji conversion key 17 is operated after inputting the desired document, the Kana / Kanji conversion section 54 performs Kana / Kanji conversion processing in the order of fixed phrases → Ikugo → Single Kanji from the beginning of the input character. . Here, if the kana character reading matches any of the candidate kanji stored in the candidate kanji storage unit 55 in advance,
A kana character to be converted is indicated by a cursor k, and a candidate kanji string of the same sound is displayed in a lower part of the display unit. Here, when the user operates the kanji selection keys 19a to 19f to specify a desired kanji in the same-sound candidate kanji, the selection signal is output to the candidate kanji storage unit 55, and the conversion target kana character is converted to kanji. In addition, the next kana character to be converted is indicated by the cursor k. In this case, the converted kanji data is transferred to and stored in the document data storage unit 56. Thereafter, the kanji selection process is repeated again in the same manner as above.
Perform Kanji conversion.

Here, when a reading of a kana character matching a kanji that does not require conversion is indicated, the cursor key 16 is operated to indicate a desired kana character, and a candidate kanji matching the reading is displayed. On the other hand, if the desired kanji does not exist in the candidate kanji displayed on the display unit 13 in the display state of the same sound candidate kanji at the time of the above-described kana / kanji conversion, the next candidate key 18 is operated to operate the control unit. Next, the next candidate signal is output to the candidate kanji storage unit 55 from 51. Then, other same-sound candidate kanji characters are displayed alternately. If a desired kanji character is present in the next candidate kanji character, the same kanji selection process as described above is repeated to perform kana / kanji conversion. If the desired Kanji is not displayed by the operation of the next candidate key 18 once,
Further, the next candidate key 18 is operated to display other same-sound candidate kanji. Here, the kanji selected and designated by the kana / kanji conversion is sequentially transferred from the candidate kanji storage unit 55 to the sentence data storage unit 56. Kana characters and symbols that do not require kana / kanji conversion are By operating the invariant (unconverted) key of the function key 15, the data stored in the converted data storage unit 52 is transferred to the text data storage unit 56 as it is. By repeating the above-described character / symbol input processing, kana / kanji conversion processing, and kanji selection processing, a desired document is created and stored in the sentence data storage unit 56.

Next, the operation for printing out the document data generated by key input as described above will be described.
To print document data, select the mode switch
Switch 11 to print mode PR position. By switching the mode changeover switch 11, the control unit 51 is set to the print mode, the text data storage unit 56 is in the reading state, and the thermal head drive circuit 57 is in the state of waiting for input of an encoder pulse from the encoder 44. In this state, the user moves the print head unit HA to the recording paper A as shown in FIG.
The device body 10 is moved in the direction of arrow X while pressing the print key 20. The rubber rollers 31, 32 rotate with the movement of the apparatus body 10, and the rotation is transmitted to the gears 34, 35a, 35b in FIG. And this gear 35a
The rotation of the encoder disk 41 rotates, and the rotation of the encoder disk 41 causes the corresponding photo sensors 43a, 43 from the LEDs 42a, 42b to pass through the slits 41a, 41b,.
The light sent to b is intermittently controlled. In this case, the device body 1
Since the encoder disk 41 is in the normal rotation state along with the movement of 0 in the X direction, the pulse signal output from the photosensor 43a becomes the output of the encoder 41, and the control unit 51 And sent to the thermal head drive circuit 57. The rotation of the rubber roller 31 is transmitted to the winding gear 36 and the ribbon winding shaft 36,
Further, it is transmitted to a take-up spool 23b in the ink ribbon cassette 22. As a result, the ribbon take-up spool 23b rotates, and the thermal transfer ink ribbon 24 guided from the ribbon feed-out spool 23a through the ribbon loading notch 26 is taken up. In this case, the ribbon winding shaft 37 is
Recording paper A and ink ribbon 24
The ink ribbon 24 is rotated by the amount of movement of the apparatus main body 10 so as not to cause slippage, and the ink ribbon 24 is recorded by a thermal head 27 having a printing pressure constantly downward by springs of slide stays 28a and 28b. Lightly pressed against paper A. Here, when the printing operation of the apparatus main body 10 in the X direction is performed, the take-up gear 36 is in a normal rotation state, and the stopper arm 38
Are held in contact with the arm stopper 40.

On the other hand, the movement amount detection signal output as an encoder pulse from the photo sensor 43a is sent to the control unit 51 and the thermal head drive circuit 57 as an output signal of the encoder 44 as described above. Then, the control unit 51 sends the sentence data storage unit 56 in accordance with the movement amount detection signal from the encoder 44.
Are sequentially designated, the document data stored therein is read, and the sentence data is output to the thermal head drive circuit 57 as individual character data through the print character generator 59. The thermal head drive circuit 57 drives the thermal head 27 in synchronization with the movement amount detection signal from the encoder 44, that is, in synchronization with the reading timing of the document data by the control unit 51. By driving the thermal head 27, the document data is thermally transferred onto the recording paper A via the ink ribbon 24.
In this case, the ink ribbon
Ink ribbon 24 from feeding spool 23a of cassette 22
The unused portion of the cassette 22 is sent out, and the used portion after being thermally transferred by the thermal head 27 is sequentially wound around a winding spool 23b in the cassette 22. By moving the apparatus body 10 in the X direction as described above, the created document data stored in the text data
Are sequentially printed. In this case, since the small apparatus main body 10 itself is moved to perform printing on the recording paper A, regardless of the size of the recording paper A, if only the print range of the created document data is secured, any recording paper A, for example, You can print on a bound notebook.

Next, a display unit corresponding to the printing operation of the document data
The display operation of 13 will be described.

First, in the initial state of the print mode PR in which the mode changeover switch 11 is switched, the displayable range of the created document data stored in the text data storage unit 56 is displayed from the beginning. When printing is started, recording paper A
The document data corresponding to the characters / symbols actually thermally transferred and printed on the display unit 13 disappears from the display unit 13, and instead, the document data in the sentence data storage unit 56 following the document data displayed so far shifts. Is displayed. Thereafter, when printing of all the document data stored in the text data storage unit 56 is completed, the display unit 13 becomes blank. That is, the operator displays the document data to be printed on the display unit.
The apparatus main body 10 is moved while performing the print processing while checking and checking the display state of 13.

Here, the document data read from the text data storage unit 56 is given to the display character generator 58 as the character code of each character data, and displayed on the display unit 13 via the display RAM 53 as a character pattern. 4th
As shown in the figure, the print control data stored together with the character code is given to a print magnification image character generator 60, and an image pattern P corresponding to the magnification is displayed together with the corresponding character data.

FIG. 6 shows a display state of the image pattern P corresponding to the set print magnification of each display character data.
"$ 153" is half-width character, "Tokyo" is 8-fold width character, "Tokyo"
Indicates that the characters are quadruple-size characters, and that "Meguro-ku" indicates full-width characters, as images corresponding to the respective print magnifications. That is, in the display state shown in FIG. 7, if the head section HA of the apparatus main body 10 is moved in the X direction while being in contact with the recording paper A, as shown in FIG. The data will be printed out. Therefore, after the print mode PR is set and before the actual print output, the print state of the document data to be printed can be imaged in advance. In this case, it is not necessary to display the display characters themselves in a size corresponding to the set print magnification, so that no inconvenience occurs even if the display area on the display unit 13 is small.

[Effect of the Invention] There is provided a means for setting a printing magnification for character data composed of input characters, symbols, and the like.
Since an image pattern of a size corresponding to the set print magnification of the character data is displayed together, the print image of the character data with the set print magnification can be easily understood even in a display unit having a small display area, for example. It becomes possible to express.
