On the other hand, a circuit board 45 is arranged between the print section 21 and the front panel of the apparatus main body 10, and the keys and switches in FIG. 1 are connected to the encoder 44 and the thermal head 27 of the print section 21. It

FIG. 3 shows the structure of an electronic circuit formed on the circuit board 45. In FIG. 3, reference numeral 51 denotes a control unit, which controls the mode changeover signal from the mode changeover switch 11. As input, various key input operation signals from the key input unit 12 and pulse signals corresponding to the movement amount of the apparatus main body 10 from the encoder 44, that is, the movement amount detection signal are input. Then, the control unit 51 controls the conversion data (key input data) storage unit 52, the display RAM 53, the Kana / Kanji conversion unit 54, and the candidate Kanji characters according to various key operation signals from the mode changeover switch 11 and the key input unit 12. Storage unit 55, text data storage unit
56, controls the thermal head drive circuit 57. The conversion data storage unit 52 sequentially stores character / symbol data such as “kana” and “symbol” input from the key input unit 12 by operating the character / symbol input keys 14 and the function keys 15. The key input character / symbol data input to the storage unit 52 is the display character generator 58 and the display RAM 53.
Is displayed on the display unit 13 via. Kana / Kanji conversion unit 54
When a conversion signal is output from the control unit 51 in response to the operation of the Kana / Kanji conversion key 17 of the key input unit 12, “Kana” in the key input character symbol data stored in the conversion data storage unit 52 is A kanji search is performed for the characters. At this time, kanji are searched in the order of fixed phrases → idioms → single kanji, and the searched kanji are stored in the candidate kanji storage unit 55 and successively output from the candidate kanji storage unit 55. And is displayed on the display unit 13. here,
In the case where the Kana / Kanji conversion unit 54 searches for a Kanji with a plurality of homonyms or homophones, and the display limit of the display unit 13 (for example, 8 characters for one lower line)
In the above cases, the next candidate signal is input from the control unit 51 by operating the next candidate key 18 of the key input unit 12, and other undisplayed candidate Kanji characters are successively displayed and sequentially displayed. When a selection signal is input to the candidate kanji storage unit 55 from the control unit 51 by operating the Kanji selection keys 19a to 19f of the key input unit 12, the selected Kanji data is stored in the text data storage unit.
It is output to 56. On the other hand, of the key input data stored in the conversion data storage unit 52, character storage data that does not require Kanji conversion is also transferred to and stored in the sentence data storage unit 56. That is, the text data storage unit 56 stores the document information created by operating the key input unit 12 as document character data including kana / kanji converted kanji, unconverted kana, katakana, symbols, and external characters.

The character and symbol data of each character of the document data stored in the sentence data storage unit 56 is output to and displayed on the display unit 13 via the display character generator 58 and the display RAM 53, and the paper sheet is also displayed. Setting key
After inputting the delimiter code "ku" for printing stop for each line printing length according to the paper size set by key input with 15b and transferring to the work area 56a, the actual character is generated via the printing character generator 59. It is called as a character and output to the thermal head drive circuit 57. The thermal head drive circuit 57 has an encoder 44 when the print mode signal and the print key signal are output from the control unit 51.
An encoder pulse is input to the thermal head 27 line by line in synchronization with the encoder pulse, and the character data input via the print character generator 59 is transferred. In this case, since the print quality of the thermal head 27 is, for example, 24 × 24 dots (full width),
The above-mentioned 1 line means 1/24 line of 1 character.

Here, in the encoder 44, when the encoder pulse is received in the order of the photosensors 43a → 43b in FIG. 2 due to the normal rotation of the encoder disk 41, the encoder pulse received by the photosensor 43a is output, and 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.

Further, a delimiter code determination unit 60 is connected between the work area 56a and the printing character generator 59. The delimiter code determination unit 60 determines whether to read out the delimiter code "ku" inserted corresponding to a preset paper size when printing the document data transferred in the work area 56a. The code judgment signal is output to the control unit 51 and the flip-flop FF.
Is supplied to the reset terminal R of the thermal head drive circuit.

Close D) to stop the printing operation. Furthermore, the control unit 5
A register 61 for setting a delimiter code for the created document data is connected to 1, and an arithmetic unit 62 having a comparison function is connected to the register 61. In the register LEN of the delimiter code setting register 61, the one-line print length set by the operation of the paper setting key 15b is set, in the register ADRS, the document data memory address of the text data storage unit 56 is set in the register ADRSE. Is the free memory start address of the text data storage unit 56, the register PADRS is the data transfer memory address of the work area 56a, and the register A is the character data stored at the address indicated by the ADRS. The register B stores the length in the printing direction of the character data stored in the register A, and the register K stores the length in the printing direction.
Fixed digit pitch data is stored. The arithmetic unit 62 subtracts the set print length LEN by the character print length B and the digit pitch K for each character transfer from the text data storage unit 56 to the work area 56a, and controls the comparison data of B or K with respect to LEN. Output to the unit 51. Further, the calculation unit 62 always reads the read start address of the transfer data in the text data storage unit 56.
ADRS is compared with the start address of the empty memory, and the comparison data is output to the control unit 51. Here, when the comparison data from the arithmetic unit 6 indicates that the remaining distance LEN of the set print length is equal to or less than the print direction length B or the fixed digit pitch K of the character data to be transferred next, The delimiter code "ku" is stored in the memory address PADRS of the work area 56a which receives the data. That is, when the data transfer from the text data storage unit 56 corresponding to the set print length is performed, the delimiter code “ku” is inserted at that time, and similarly, the document data in the text data storage unit 56 is The above data transfer / delimiter code insertion processing is repeated until there is no more. A print length table 63 corresponding to the set paper size is connected to the control unit 51,
Paper setting key 15b and next candidate key 1 in the key input unit 12
The print length data corresponding to the paper size set by the operation of 8 is continuously output from the print length table 63 and set in the register LEN.

FIG. 4 shows the contents of the print length table 63, and the paper size for printing is, for example, A ₃ , A ₄ ,
Vertical and horizontal of B ₄ and B _5, respectively, and vertical and horizontal of the postcard,
Further, the print length of the envelope can be set.

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

First, to create the desired document, switch the mode
Operate 11 to specify the word processor mode WP. Then, the control unit 51 is set to the word processor 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, the character / symbol input key 14 and the function key 15 are operated to key-in the document information to be created, and the input document data is sequentially transferred to the converted data storage unit 52 which is addressed via the control unit 51. It At the same time, the input document data is displayed in the character generator 58 for display and the RA for display.
It is displayed on the display unit 13 via M53. When the kana / kanji conversion key 17 is operated after inputting the kana of the desired document, the kana / kanji conversion unit 54 performs kana / kanji conversion processing from the beginning of the input characters in the order of fixed phrase → compound words → single kanji. Done. Here, when the reading of a kana character matches any of the candidate kanji stored in the candidate kanji storage unit 55 in advance, the kana character to be converted is indicated by the cursor k, and the candidate kanji string of the same sound is displayed. Displayed at the bottom of the display. Here, when the user operates the Kanji selection keys 19a to 19f to specify a desired Kanji among the same-sound candidate Kanji, the selection signal is output to the candidate Kanji storage unit 55, and the Kana character to be converted is converted into Kanji. In addition, the kana character to be converted next 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. After that, repeat the Kanji selection process again as above /
Perform kanji conversion.

Here, when the reading of the kana character that matches the kanji that does not need to be converted is displayed, the cursor key 16 is operated to indicate the desired kana character, and the candidate kanji that matches the reading is displayed. On the other hand, in the display state of the same-sound candidate kanji during the above series of kana / kanji conversion, if the desired kanji does not exist among the candidate kanji displayed on the display unit 13, the next candidate key 18 is operated to operate the control unit. The next candidate signal is output from 51 to the candidate Kanji storage unit 55. Then, other same-sound candidate kanji are replaced and displayed. If a desired kanji exists in the next candidate kanji, the kanji selection process similar to the above is repeated to perform kana / kanji conversion. If the desired Kanji is not displayed by operating the next candidate key 18 once,
Further, the next candidate key 18 is operated to display another homophone candidate kanji. Here, the kanji selected and designated by kana / kanji conversion are sequentially transferred from the candidate kanji storage unit 55 to the text data storage unit 56, but kana characters, symbols, etc. that do not require kana / kanji conversion are By operating the unchanged (non-conversion) key of the function key 15, the storage data in the conversion data storage unit 52 is transferred to the text data storage unit 56 as it is. By repeating the character / symbol input process, kana / kanji conversion process, and kanji selection process described above, a desired document is created and stored in the sentence data storage unit 56.

Next, the operation of printing out the document data created by key input as described above will be described. When printing document data, the mode selection switch 11
To the print mode PR position. The control unit 51 is set to the print mode by the switching of the mode changeover switch 11. Especially, when the paper size is not set,
The created document data in the text data storage unit 56 is transferred to the work area 56a as it is, the work area 56a is in a read state, and the thermal head drive circuit 57 is connected to the encoder 44.
Waiting for input of encoder pulse from. In this state, as shown in FIG. 1, the user brings the print head portion HA into contact with the recording sheet A and moves the apparatus body 10 in the direction of arrow X while pressing the print key 20. The rubber rollers 31 and 32 rotate as the apparatus body 10 moves, and the rotation of the rubber rollers 31 and 32 moves to the second position.
It is transmitted to the gears 34, 35a, 35b in the figure. The encoder disk 41 rotates with the rotation of the gear 35a, and the rotation of the encoder disk 41 causes the LEDs 42a,
The light sent from 2b to the corresponding photosensors 43a, 43b via the slits 41a, 41b, ... Is intermittently controlled. In this case, since the encoder disk 41 is in the normal rotation state as the apparatus body 10 moves in the X direction, the pulse signal output from the photo sensor 43a becomes the output of the encoder 41, and the movement amount detection signal for the apparatus body 10 is output. Is sent to the control unit 51 and the thermal head drive circuit 57. The rotation of the rubber roller 31 is performed by the winding gear 36 and the ribbon winding shaft 36.
Is further transmitted to the take-up spool 23b in the ink ribbon cassette 22. As a result, the ribbon take-up spool 23b rotates and the ribbon take-up spool 23a
The thermal transfer ink ribbon 24 guided from the ribbon loading notch 26 is wound up. In this case, the ribbon take-up shaft 37 does not cause slippage between the recording paper A and the ink ribbon 24 as the apparatus body 10 moves.
It rotates according to the movement amount of 10 and also the ink ribbon 24
Is lightly pressed against the recording paper A by the thermal head 27 which always has downward printing pressure by the springs of the slide stays 28a and 28b. Here, during printing movement of the apparatus body 10 in the X direction, the winding gear 36 is in the normal rotation state, and the stopper arm 38 is 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 the output signal of the encoder 44 as described above. Then, the control unit 51 causes the encoder
The memory address of the work area 56a is sequentially designated according to the movement amount detection signal from 44, the document data stored therein is read out, and this document data is driven through the printing character generator 59 as individual character data to drive the thermal head. Output to circuit 57. 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 storage paper A via the ink ribbon 24. In this case, as the apparatus body 10 moves, the unused portion of the ink ribbon 24 is delivered from the pay-out spool 23a of the ink ribbon cassette 22, and the used portion after the thermal transfer by the thermal head 27 is used in the cassette. The winding spool 23b in 22 is sequentially wound up. By operating the apparatus body 10 in the X direction as described above, the created document data stored in the text data storage unit 56 is sequentially printed on the recording paper A. In this case, since the small apparatus body 10 itself is moved to print 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, for example, binding It can also be printed on a notebook.

Next, the printing operation when the size of the print recording paper A is set and the one-line print length is determined will be described.

First, after the document creation process in the word processing mode WP, in order to set the one-line print length according to the size of the recording paper A, operate the paper setting key 15b in the key input unit 12,
Further, the next candidate key 18 is operated. Then, FIG. 5 (A)
As shown by (D) to (D), different paper sizes are displayed each time the next candidate key 18 is operated. Here, if the execute key 15a is operated with the paper size corresponding to the desired print recording paper A displayed on the display unit 13, the print length data corresponding to the paper size is set. When the operation mode is set to the print mode PR by the mode changeover switch 11, the edit processing of the document data according to the set print length corresponding to the paper size of the print recording paper A as described below is executed.

FIG. 6 is a flow chart showing the editing process of the document data. First, the print length of one line set by the designation of the paper size is continuously output from the print length table 63 to the register LEN and to the register ADRS. The continuous start address in the data storage unit 56, the start address of an empty memory in the text data storage unit 56, and the write start address of the work area 56a are set in the register ADRSE (step S1). In this way, when the initial setting of each data is completed, it is determined whether or not the read address ADRS for the text data storage unit 56 has reached the empty memory address ADRSE based on the comparison data from the calculation unit 62. , Register A above AD
The character data in the text data storage unit 56 stored in the address designated by RS is set, and the print direction length of the character data set in the register A is set in the register B (steps S2 ... S4). Here, based on the comparison data from the calculation unit 62, the one-line print length is longer than the print direction length B of the character data set in the register A.
If it is determined that LEN is longer, it is possible to set new character data within the set print length.
The character data in the register A is transferred and written in the memory in the work area 56a addressed by the PADRS (steps S5 and S6).

Then, the remaining one-line print length obtained by subtracting the print length B of the character data transferred to the work area 56a from the initially set one-line print length LEN is newly set as LEN, and the text data storage unit in the register ADRS is set. Subsequent address for 56, and work area 56a in register PADRS
Update the write address for (step S7, S
8). Here, based on the comparison data from the calculation unit 62, the remaining one-line print length LE calculated in step S7 is calculated.
When N is determined to be longer than the digit pitch K, the remaining one-line print length obtained by subtracting the digit pitch K from the current one-line print length LEN is newly set as LEN (step S9,
S10). Thus, first, after the processing of steps S2 to S10, the data transfer for one character from the text data storage unit 56 to the work area 56a is completed. In this case, the remaining one-line print length currently set in the register LEN is the work area 56 in step S6.
It is a value obtained by subtracting the print length B and the digit pitch K of the character data transferred to a.

After this, while repeating the transfer processing of each character of the document data in steps S2 to S10, in step S5 (N
O), that is, the current remaining one-line printing length LEN is judged to be less than the printing length of the character data to be transferred next, or (NO) in step S9, that is, the currently remaining one-line printing length LEN is If it is determined that the digit pitch is less than or equal to the digit pitch, it means that the document data of the data amount corresponding to the one-line print length set in advance in the paper is transferred from the text data storage unit 56 to the work area 56a. When the control unit 51 has a work area 56a addressed by the updated PADRS.
A delimiter code "ku" as a print stop command at the time of print processing is written in the internal memory (step S11). Then, again, the write address PADRS of the work area 56a is updated (step S12).

That is, by repeating the processing in steps S2 to S12, for example, the document data stored in the text data storage unit 56 can be printed at each line printing length corresponding to the size of the print recording paper A preset by the paper setting. The delimiter code is inserted into the work area 56a to be delimited, and the work area 56a is transferred and edited. Then, in step S2, (YE
S) That is, when the continuous address ADRS in the text data storage unit 56 reaches the top address ADRSE of the empty memory and it is determined that the transfer of all the document data is completed, the work area 56a is set to the read state and the thermal head is driven. The circuit 57 waits for the input of the encoder pulse and waits for the start of printing.

Here, when the print key 20 is operated and the apparatus body 10 is moved in the X direction on the recording paper A and the printing operation is started, the document data transferred and stored in the work area 56a is
While the delimiter code judgment unit 60 judges whether or not the read data is a "ku" code, the thermal head drive circuit 57 is sequentially passed through the printing character generator 59.
Sent to. This allows the device body from the encoder 44 to
The thermal transfer printing of the document data is started via the thermal head 27 in synchronization with the movement amount detection signal of 10.

When the "division" code, which means a break from the next print line, is read from the text data storage unit 56 during the printing process of the document data when the one-line print length is set by this paper setting, the delimiter code determination unit The detection signal is output from 60, and the encoder pulse is no longer supplied to the thermal head drive circuit 57. As a result, the printing operation is stopped, and one line is printed according to the set print length for one line corresponding to the size of the print recording paper A. After that, when the print key 20 is pressed again and the operation of moving the apparatus body 10 from the left end of the recording paper A is repeated, the created document data is easily printed in order on the second line, the third line, ... The length can be aligned with the right end of the recording paper A and printed out.

Therefore, according to the printing apparatus having the above-mentioned configuration, not only can printing be performed from any position on any paper, but also the paper can be set in accordance with the size of the print recording paper A to set the print length for one line. It is possible to easily obtain a print format in which the print length of each print line is adjusted to the recording paper A.
