Abstract

PURPOSE:To enable a printing to be conducted even on a bound notebook or a recording paper of more than a specified size and to enable a printing end time point to be definitely known, by a method wherein a means which prints stored character data on the recording paper by traveling a device body and a means which issues a warning at the completion of printing are provided. CONSTITUTION:Due to the rotation of rubber rollers 31, 32 accompanying the travel of a device body 10, an encoder disk 41 rotates and the light to be sent to photosensors 43a, 43b is intermittently controlled. This is sent to a control part 51, a thermal head drive circuit 57, and a counter 63 as a travel amount detection signal and, simultaneously, a ribbon take-up spool 23b rotates. If the total number of printing lines of the document data to be printed which is preset in a printing line number register 62 concides with the count data of the encoder pulses counted by the counter 63, an arithmetic part 61 outputs a printing end signal. In this manner, the control part 51 outputs a buzzer drive signal to a buzzer drive part 64.

This mode changeover switch 11 is used to turn on/off the power,
It also switches between word processing mode (document creation mode) WP and print mode (printing mode) PR, and is turned on when word processing mode WP or print mode PR is specified. On the other hand, a key manual section 12 and a display section 13 are provided on the front side of the device main body 1o.

The key input unit 12 includes a character/symbol input key 14, a function key 15, a cursor key 16, a kana/kanji conversion key 17,
A next candidate key 18, kanji selection keys 19a to 19f, and a print key 20 are arranged.

Here, the display section 13 displays a total of 16 characters, for example, in two lines above and below. Further, on the lower surface of the apparatus main body 10, a print head section HA is provided, which includes a line-type thermal head of, for example, 48 dots per line, with the line direction facing the width direction of the apparatus main body 10.

The above character/symbol input key-14 is for inputting kana in the created document,
Alternatively, it is used in conjunction with the function keys 15 to input alphanumeric characters, symbols, etc., and the function keys 15 can, for example, be used to input the start and end of document input, or to specify the range of movement on a document using the cursor k. Keys for specifying various functions necessary for document creation and printing using the character/symbol entry keys 14 are arranged, including an execution key 15a for delimiting, as well as insert, delete, and shift keys. The characters and symbols input using the character/symbol entry key 14 and the recovery key 15 are displayed in sequence on the display section 13.

The cursor key 16 is used to move a cursor k displayed on the display section 13 together with the input text and symbols in the left and right direction, and by moving this cursor, an input position, a functional range, etc. are specified. Kana/Kanji conversion key 17 is
The created document entered in kana using the above character/symbol input key 14 is a fixed phrase.

It is used to convert Kana to Kanji for each compound word or single kanji. At this time, a predetermined number of kanji to be converted are displayed on the display section 13 along with the kana document to be converted, and the next candidate key 18 is operated. A number of other homonyms appear in turn. When a kanji to be converted is displayed on the display section 13 through this kana/kanji conversion, the desired kanji is selected and specified using the corresponding kanji selection keys 198 to 19f.

That is, a desired document is created by specifying the word processing mode WP using the mode changeover switch 11 and repeating the manual key operations for characters and symbols, the kana/kanji conversion operation, and the kanji selection operation. When printing a manually created document, after specifying the print mode PR with the mode changeover switch 11, the head unit 1-I
A is brought into contact with the recording paper A side, and the apparatus main body 10 is moved in the direction shown by the arrow X while pressing the print key 20. As a result, the created wording is printed. In this case, for example, when printing of all created documents is completed, the electronic circuit within the apparatus main body 10 detects that there is no more document data to be printed, and a buzzer sounds.

At the lower end of the ribbon cassette 22, a part of the ribbon cassette 22 is exposed from the head installation notch 25 and set. A ribbon loading notch 26 is formed in the printing head section HA of the printing section 21, and a thermal head 27 is installed in the center of this notch 26 with the head slightly protruding from the bottom surface of the apparatus main body 10. Placed. This thermal head 27 is mounted so that it can be moved slightly up and down by slide stays 28a and 28b that are erected on a member 28, and is constantly lowered by the action of a spring that is integrally wound around the stays 288 and 28b. The printing pressure in the direction is maintained. Roughly speaking, on the lower surface side of the apparatus main body 10 where this thermal head 27 is arranged, there is a notch 2 for loading the ribbon.
Two large and small openings 29, 30 are formed on both sides of 6, and rubber rollers 31, 32 are arranged in each of them. These rubber rollers 31 and 32 are used in the apparatus main body 1 during printing operations.
When the rubber roller 31 is moved in the direction indicated by the arrow X, it rotates in contact with the recording paper, and a tooth width 33 is coaxially fixed to one side of the rubber roller 31. This gear 33
is formed to have a smaller diameter than the rubber row 531, and the gear 34.3
It is connected to the winding gear 36 via 5a and 35b. A ribbon winding shaft 37 is installed coaxially with the winding gear 36, and a stopper arm 38 is attached to the base of the winding shaft 37, which presses against the winding gear 36.

This stopper arm 38 rotates in the direction in which the gear 36 rotates due to pressure contact with the winding gear 36, and a stopper gear 39 that meshes with the winding gear 36 is provided at the tip of this arm 38. It will be done. Further, an arm stopper 40 is provided in the rotating direction of the arm 38 that corresponds to the winding rotation direction of the winding shaft 36. Here, take-up gear 3

41b, . . . are formed radially at regular intervals,
LEDs are placed adjacent to each other at two positions facing each other with the slit forming part in between of the encoder disk 41.
42a, 42b and photosensors 43a, 43b are arranged. In this case, the projected light from the LEDs 42a and 42b is transmitted through the slits 41a and 41b of the encoder disk 41.
, ... and enters the photosensors 43a, 43b. When the encoder disk 41 rotates forward due to movement of the main body 10 in the X direction, the photosensors 43a→
In the order of 43b, and if reversed, in the order of 43b → 43a,
Projection light from each corresponding L-ED 42a, 42b enters. In other words, the encoder disk 41, the LED 42a
, 42b, lttose>+j 43a, 43b, etc. constitute the encoder 44. And this print 1lI
The ink ribbon cassette 22 is attached to the X21 using the ribbon winding shaft 37 as a support shaft. In this case, the thermal transfer ink ribbon 24 exposed in a part of the lower end of the ribbon cassette 22 is set in contact with the head surface of the thermal head 27 disposed in the ribbon loading notch 26 of the apparatus main body 10. Ru. Here, the device main body 10
The back cover 10a is configured to be openable and closable by a hinge 10b, so that operations such as replacing the ink ribbon cassette 22 and inspecting the inside can be easily carried out.

On the other hand, a circuit board 45 is arranged between the print section 21 and the front panel of the main body 10, and the keys and switch group shown in FIG. 1, as well as the encoder 44 and the thermal head 27 of the print section 21 are connected. Ru.

FIG. 3 shows the configuration of an electronic circuit formed on the circuit board 45. In the figure, 51 is a control section, and this control section 51 receives mode change signals such as mode change signals from the mode change switch 11. , various key manual operation signals from the key manual unit 12 and pulse signals from the encoder 44 according to the amount of movement of the Ri1 main body 10, that is, the movement 1t) f
The fl detection signal is input. Then, the control section 51 converts the conversion data (key manual data) in response to various key operation signals from the mode changeover switch 11 and the key manual section 12.
Storage unit 52, display RAM 53, kana/kanji conversion unit 54
, the candidate kanji storage section 55, the text data storage section 56, the thermal head drive circuit 57, etc.

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 entry keys 14 and the function keys 15. Key human input character/symbol data input into the data storage section 52 is displayed on the display section 13 via the display character generator 58 and the display RAM 53.

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 human power unit 12, the kana/kanji conversion unit 54 converts the key human power character symbol data stored in the conversion data storage unit 52. This is a search for kanji that corresponds to the ``kana'' character in the ``kana'' character.
The search is performed in the order of single kanji characters, and the searched kanji characters are stored in the candidate kanji storage section 55, read out from the candidate kanji storage section 55, and displayed on the display section 13. Here, if the kanji searched by the above-mentioned kana/kanji conversion unit 54 has multiple homophone 1a words or homophone allographs, the display unit 13 can display 8 characters for the lower line, for example. ) or more, the next candidate signal is input from the control section 51 by operating the next candidate key 18 of the key input section 12, and the candidate kanji characters for the other undisplayed valves are read out and displayed in turn.

When a selection signal from the control unit 51 is input to the candidate kanji storage unit 55 by operating the kanji selection keys 19a to 19f of the key input unit 12, the selected kanji data is output to the text data storage unit 56. On the other hand, among the key manual data stored in the conversion data storage section 52, character symbol data that does not require kanji conversion is also stored in the text data storage section 52.
6 and stored. That is, the text data storage unit 56 stores the document information created by the operation of the key human power unit 12 as document character data consisting of kanji converted to kana/kanji, unconverted kana, katakana, symbols, and external characters. .

Character and symbol data of individual characters of the document data stored in the text data storage section 56 are output to the display section 13 via the display character generator 58 and the display RAM 53 for display, and are also used for printing. It is converted into an actual character pattern via the character generator 59 and transferred to the print data storage section 60. The document data stored as a dot pattern in the print data storage section 60 is output to the thermal head drive circuit 57. The thermal head drive circuit 57 includes
When the print mode signal and the print key signal are output from the control unit 51, an encoder pulse from the encoder 44 is input, and character data input from the print data storage unit 60 in synchronization with this encoder pulse is 1
It is transferred to the thermal head 27 line by line. in this case,
The print quality by the thermal head 27 is, for example, 24×2.
Since there are 4 dots (full-width), the above-mentioned 1 in means 1/24 line of 1 character.

Here, in the encoder 44, when the encoder disk 41 rotates forward and the engoder pulses are received in the order of photosensors 43a→43b in FIG. 2, the encoder pulses received by the photosensor 43a are output, and When the encoder pulses are received in the order of photosensors 43b and 43a due to the reverse rotation of the encoder disk 41, the encoder pulses are no longer output.

In other words, if the encoder disk 41 is reversed, even when the print mode PR is set, the thermal head 27
will not be driven.

Further, a calculation unit 61 having a comparison function is connected to the control unit 51, and this calculation unit 61 includes a print line number register 6.
2 is connected. When the printing document data stored in the text data storage section 56 is converted into a dot pattern by the printing character generator 59 and transferred to the printing data storage section 60, the calculation section 61 calculates one of the transferred character patterns. The number of printing lines corresponding to the character size of each character is calculated and added to the printing line number register 63. When adding the number of lines for each character of the document data to be printed to the printing line number register 62, the number of lines corresponding to the character size of each character is calculated at the same time. The number of lines corresponding to the interdigit pitch is also added.

In other words, the print line number counter 62 is ultimately set with the total number of print lines from the beginning to the end of the document data to be printed.

On the other hand, the calculation section 61 is supplied with count data from a counter 63 that performs a count-up operation in response to encoder pulses when printing document data to be printed. In this case, the calculation unit 61 compares the total number of print lines of the document data to be printed, which is set in advance in the print line number register 62, and the count data of encoder pulses given from the counter 63, and if the two match, the control unit 61 performs control. 11 outputs a print end signal to section 51. In other words,
Since 1724 lines (full-width characters) of printed character data are printed out for each encoder pulse from the encoder 44, the coincidence of the total number of printed lines of the above-mentioned printed document data and the count data of the encoder pulse is based on the document data. This means that the final character data has been printed out.

Here, when the control section 51 receives the print end signal from the arithmetic section 61, it outputs a buzzer drive signal to the buzzer drive section 64 to activate the buzzer 65.

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

First, in order to create a desired document, the user operates the mode changeover switch 11 to designate word processing mode WP. Then, the control section 51 is set to word processing mode WP. Here, the user is I! 1 Operate the key manual section 12 of the main body 10 to input desired characters, symbols, etc. in sequence.

First, when the character/symbol input key 14 and the function key 15 are operated to input document information to be created, the input document data is sequentially transferred to the converted data storage section 52 whose address is specified via the control section 51. The characters are displayed on the display section 13 via the character generator 58 and the display RAM 53.

After inputting kana for the desired document, when the kana/kanji conversion key 17 is operated, the kana/kanji conversion unit 54 converts the input characters into kana/I in the order of fixed phrases → compound words → single kanji from the beginning.
Character conversion processing is performed. Here, if the pronunciation 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 on the cursor, and a string of candidate kanji with the same sound is displayed. Displayed on the bottom row. Here, the user presses the kanji selection keys 198-19
When a desired kanji among the homophone candidate kanji is specified by operating f, a selection signal is output to the candidate kanji storage section 55, and the kana character to be converted is converted into a kanji, and at the same time it is selected as the next conversion target. The character is indicated by the cursor. In this case, the converted kanji data is transferred to and stored in the document data storage section 56. Thereafter, the kanji selection process is repeated again in the same manner as above to perform kana/lI character conversion.

771 If the reading of the ``Taisho T Ura Gaisho'' or 1-1 is shown, use the cursor key 16 to indicate the desired kana character, and display candidate kanji that match that reading. let On the other hand, in the display state of the homophone candidate kanji during the series of kana/kanji conversions, if the desired kanji does not exist among the candidate kanji displayed on the display section 13, the next candidate key 18 is operated and the control section Candidate kanji storage section 5 from 51
5 to output the next candidate signal. Then, other homophone candidate kanji are displayed in exchange, and if the desired kanji exists among the next candidate kanji, the same kanji selection process as above is repeated again to perform kana/kanji conversion. Further, if the desired kanji is not displayed by the single operation of the next candidate key 18, another homophone candidate kanji is displayed by further operating the next candidate key 18. Here, the kanji selected and designated by kana/il1 character conversion are sequentially transferred from the candidate kanji storage section 55 to the text data storage section 56, but the characters, symbols, etc. that do not require kana/kanji conversion are , by operating the heat level (no conversion) key of the function keys 15, the text data storage unit 5 can be stored as the stored data in the conversion data storage unit 52.
Transferred to 6. By repeating the above character symbol input processing, kana/kanji conversion processing, and kanji selection processing, a desired document is created and stored in the text data storage section 56.

Next, an explanation will be given of the operation when printing out the document data created manually as described above. To print document data, press mode selector switch 1.
1 to the pudding 1 to mode PR position. By switching the mode changeover switch 11, the control section 51 is set to the print key, and first, the text data storage section 56 is set to the print key.
Then, the character pattern conversion transfer process of the document data to be printed to the print data storage section 60 is performed, and the print data storage section 60 is in the reading state, and the thermal head drive circuit 57 is waiting for the input of encoder pulses from the encoder 44. state. In this case, the total number of print lines of the document data to be printed is set in the print line number register 62 by the calculation unit 61.

FIG. 4 is a flowchart showing the calculation process for the number of print lines of the above-mentioned document data to be printed.
When the print line number register 62 is reset by the setting of R, the document data to be printed, which is read from the text data storage section 56, converted into a character pattern by the printing character generator 59, and transferred to the print data storage section 60, is The character size is determined for each character data, and the number of print lines corresponding to the character size is added and set in the print line number register 62 (steps 81 to 84). In other words, if the read character is half-width size, 1412 when in horizontal writing mode, ``'' 2 when in vertical writing mode.
4" in full-width size, '24' in both horizontal and vertical writing modes, and in double-height size,
"24" in horizontal writing mode, "48" in 11@@ mode, if horizontal double size, am 4 B + t in horizontal writing mode, 1124 in vertical writing mode.
When II is 4x size, '48'' is displayed in both landscape and IS mode, and when II is 8x size,
When in II mode, “79” is Sansaimo F: Mesaba”
A A” corresponding steps 54a-84f, respectively.
The value is added and set in the print line number register 62 at . In this case, each time the number of lines printed for one character is added, the number of lines corresponding to the digit pitch between characters is also added (step 35).

After that, in step S3, it is determined that there is no more read data from the text data storage section 56, or
Alternatively, if the printing line number addition processing in steps 82 to S5 is repeated until it is determined that a special code that means printing stop, which is stored in advance with the document data, has been read out, at this point, the printing line number register 62 is ,
This means that the total number of print lines of the document data to be printed has been set.

In this state, as shown in FIG. 1, the user brings the print head section HA into contact with the recording paper container, and moves the apparatus main body 10 in the direction of the arrow X while pressing the print key 20. As the device main body 1o moves, the rubber rollers 31.32 rotate, and this rotation causes the gears 34.35a, 35 in FIG.
transmitted to b. As the gear 35a rotates, the encoder disk 41 rotates, and the rotation of the encoder disk 41 causes the LEDs 42a, 42b to send signals to the corresponding photosensors 43a, 43b via the slits 41a, 41b, . The intermittent light is controlled. In this case, as the apparatus main body 10 moves in the
This output is sent to the control section 51, the thermal head drive circuit 57, and the counter 63 as a movement detection signal for the apparatus main body 10. In addition, the above rubber row 53
1 rotation is transmitted to the take-up gear 36 and the ribbon take-up shaft 36, and further to the take-up spool 23b in the ink ribbon cassette 22. This causes the ribbon take-up spool 23b to rotate and wind up the thermal transfer ink ribbon 24 that has been guided from the ribbon pay-out spool 23a through the ribbon loading notch 26. in this case,
The ribbon winding shaft 37 rotates in accordance with the amount of movement of the apparatus main body 10 to prevent slippage between the recording paper A and the ink ribbon 24 as the apparatus main body 10 moves. 24 are slide stays 28a, 28
The recording paper A is lightly pressed against the recording paper A by the thermal head 27 which constantly applies downward printing pressure due to the spring b. Here, when the li1 main body 10 moves in the X direction for printing, the take-up gear 36 is in a normal rotation state, and the stopper arm 38 is held in contact with the arm stopper 40.

On the other hand, the movement detection signal output as an encoder pulse from the photosensor 438 is sent to the control section 51, the thermal head drive circuit 57, and the counter 63 as an output signal of the encoder 44, as described above. Then, the 1b1310 section 51 sequentially specifies the memory addresses of the print data storage section 60 in accordance with the movement amount detection signal from the encoder 44, reads out the document data stored therein as a character pattern, and reads this document data. It is output to the thermal head drive 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 document data by the tllIII section 51. By driving the thermal head 27, the document data is thermally transferred onto the recording paper A through the ink ribbon 24 one to six inches at a time. In this case, as the apparatus main body 10 moves, the ink ribbon cassette 22
The unused portion of the ink ribbon 24 is fed out from the feeding spool 23a, and the used portion after being thermally transferred by the thermal head 27 is sequentially wound onto the take-up spool 23b in the cassette 22. By moving the apparatus main body 10 in the X direction as described above, the created document data stored in the text data storage section 56 is sequentially printed on the recording paper A. In this case, since the small device main body 10 itself is moved to print on the recording paper A, regardless of the size of the recording paper A, as long as only the printing range of the created text data is secured, it can be printed on any recording paper A. It can also be printed.

- When the total number of print lines of the document data to be printed, which has been set in advance in the print line number register 62, matches the count data of the encoder pulses counted by the counter 63, the calculation unit 61 finishes printing. Output a signal. Then, the control unit 51 outputs a buzzer drive signal to the buzzer drive unit 64 to activate the buzzer 65. As a result, the operator can clearly know when the printing of the document data to be printed ends, and there is no need to move the main body 10 of the apparatus for printing. Therefore, ink ribbon 2
Inconveniences such as wasting 4 will be resolved.

In the above embodiment, the created document data is converted into a -H character pattern, transferred and stored in the print data storage section 60, and read data from the print data storage section 60 is outputted to the thermal head drive circuit 57. Although the configuration is configured to perform printing, document data converted to a character pattern via the printing character generator 59 is
In the case of direct connection, an electronic circuit configuration as shown in FIG. 5 may be used.

In this case, the print data storage section 60, the calculation section 61 . The printing line number register 62° counter 63 is not necessary, and a printing character generator 59 is interposed between the text data storage section 56 and the thermal head drive circuit 57.
The read data for 9 is also provided to the data determining section 66. This data judgment unit 66 determines whether there is no longer any document data to be printed from the text data storage unit 56, or if the read data contains a special code indicating that printing has stopped.
The print end signal from the data judgment unit 66 is output to the control unit 51 and also to the AND gate AND via the inverter INV, and is used to drive the thermal head. The operation of supplying encoder pulses to circuit 57 is blocked.

That is, during printout of a created document, when a "stop" code following the document data to be printed is read from the text data storage section 56 or when there is no more data to be printed, the data judgment section 66 outputs a print end signal. be done. As a result, the AND gate AND is closed and the printing operation is stopped, and at the same time, the control section 51 outputs a buzzer drive signal to the buzzer drive circuit 64 to activate the buzzer 65. Therefore, the operator can eliminate unnecessary printing operations without having to move the apparatus main body 10 extraneously.

[Effects of the Invention] As described above, according to the present invention, the present invention includes a printing means for printing arbitrary character data such as characters and symbols that are manually memorized on a recording paper by moving the main body of the apparatus. When the printing means finishes printing the above-mentioned arbitrary character data, the M signal is emitted by a buzzer or the like, so it is possible to print on, for example, bound notebooks or recording paper larger than the specified size. It is possible to provide a small-sized character printing device that makes it possible to clearly know when the print output of print data ends.
