A specified printing length for one line is set in a register LEN, a digit pitch is set in a register K, the character data in a storage part 56 is set in a register A, and the printing-direction length of the character data set in the register A is set in a register B. During the repeat of a printing processing per character, the previously designated document data is read from the sentence data storage part 56 and, then, the control part 51 outputs a printing stop command.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides small characters that are printed on recording paper by moving the main body of the device to obtain sub-scanning of character data such as sentences created by manual key operation. Regarding printing devices.

[Prior Art and its Problems] Conventionally, typewriters, word processors, and the like have been widely used as devices for manually creating sentences and printing them to obtain documents. In these typewriters and word processors, recording paper of a predetermined size (A4.85, etc.) is usually wound and set around the roller of the printer section built into the device, and ink, ribbon, etc. The created document is printed by transferring the characters through the printer.

However, in the above-mentioned document creation device, for example, an O-ra rotation mechanism or a print head sliding mechanism for moving the printing position of characters on the recording paper is required, and the printer section becomes large. There is a problem in that it is difficult to downsize the device body. Further, in a document creation device having a printer section built into the main body, it is not possible to print a created document on, for example, a bound notebook or recording paper larger than a specified size.

Therefore, a printing device that performs printing by manually moving the main body of the device has been considered, but since the printing length for one line is not specified equally, for example, the printing character at the end of the printing line may be missing or missing. It is extremely difficult for an operator to perform a printing operation by aligning the printing length of each line.

[Purpose of the Invention] The present invention has been made in view of the above-mentioned problems. For example, even on bound notebooks or recording paper of a specified size or larger, it is possible to print arbitrary characters according to the size of the recording paper. An object of the present invention is to provide a small-sized character printing device capable of specifying a length and performing printing processing without causing missing or overlapping printed characters.

[Summary of the Invention] That is, the small character printing device according to the present invention includes means for printing input and stored data on recording paper by moving the main body of the device, designating the printing length for one line,
When the printing means prints the stored data, the printing operation is stopped when the designated printing length is reached.

[Embodiments of the invention] A practical example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the external configuration of a printing device embodying the present invention, and the H1 main body 10 is constructed of a size that is large enough to be held in the user's hand. First, a mode changeover switch 11 is provided on the left side of the device main body 10. This mode changeover switch 11 is used to turn the power on and off, and to switch between word processing mode (document creation mode) WP and print mode (printing mode) PR. is turned on. On the other hand, a key manual section 12 and a display section 13 are provided on the front surface of the 8-position main body 10.

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 GI 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. Starting with an execution key 15a for dividing, insert, delete, and shift keys, a print length key 15b for specifying the print length for one line, a digit pitch key 15c for specifying the pitch between print digits, an enlargement key 15d1, a reduction key 15
Keys such as e, etc., are arranged to designate various functions necessary for document creation/printing using the character/symbol entry key 14. The characters and symbols input using the character/symbol input keys 14 and the function keys 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 along with the input text layer and symbols in the left and right direction, and by moving this cursor, the input position, functional range, etc. are specified. The Kana/Kanji conversion key 17 is used to convert the document entered into Kana using the character/symbol entry key 14 from Kana to Kanji for each fixed phrase, compound word, or single kanji. A predetermined number of the above kanji are displayed together with the Kana document to be converted on the display unit 13, and by operating the next candidate key 18, many other homonyms are displayed in turn. When the 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 19a 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 print mode PR with the mode selector switch 11, bring the head HA into contact with the recording paper Δ side, and press the print key 20 while pressing the main body 10 of the device.

Two large and small openings 29 and 30 are formed on both sides of the ribbon loading notch 26 on the lower surface side of the ribbon 0, and rubber rollers 31 and 32 are arranged in each of the openings 29 and 30, respectively. This rubber row 5
Reference numerals 31 and 32 rotate in contact with the printing paper A when the main body 10 of the apparatus is moved in the direction shown by the arrow X during a printing operation, and one rubber roller 31 has a coaxial roller on its side. A gear 33 is fixed to. This gear 33 is formed to have a smaller diameter than the rubber roller 31, and has a one-way clutch 34,
It is connected to a ribbon winding shaft 36 via gears 35a and 35b. Further, the one-way clutch 33 includes a gear 37a,
Encoder disk 38 is connected 311 via 37b. Here, the one-way clutch 33 is configured to transmit the rotation of the primary side to the secondary side, that is, the rotation of the rubber row 531 to the ribbon winding shaft 36 and the encoder disk 38 only during printing operation in the direction of arrow X. It has become. This encoder disk 38 has a plurality of slits 38a, 38b.
, . . . are formed radially at regular intervals, and the LED 39 and the photosensor 40 are arranged at positions facing each other with the slit forming portion of the encoder disk 38 interposed therebetween.

In this case, the projected light from the LEo 39 passes through the slits 38a, 38b, . . . of the encoder disk 38 and enters the photosensor 40. In other words, the encoder 41 is composed of the encoder disk 38, the LED 39, the photosensor 40, and the like. For this print section 21, a ribbon winding shaft 36 and a shaft 4 paired therewith are provided.
An ink ribbon cassette 22 is mounted using 2 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 along the head surface of the thermal head 27 arranged in the ribbon loading notch 26 of the apparatus main body 10. . Here, the back 110a of the apparatus main body 10 is configured to be closed 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 43 is disposed between the print unit 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 41 and thermal head 27 of the print unit 21 are connected Ru.

FIG. 3 shows the configuration of an electronic circuit formed on the circuit board 43, in which 51 is a $ control section;
The control section 51 receives a mode switching signal from the mode switching switch 11, various key manual operation signals from the key manual section 12, and a pulse signal from the encoder 41 according to the amount of movement of the device main body 10. , a moving solder detection signal is input. Then, the control section 51 controls the conversion data (key human power data) storage section 5 in response to various key operation signals from the mode changeover switch 11 and the key human power section 12.
2. Controls the display RAM 53, the kana/kanji conversion unit 54, the candidate kanji storage unit 55, the text data storage unit 56, and 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 Pi 112 by operating the character/symbol input key 14 and the functional key 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 section 51 in response to the operation of the kana/kanji conversion key 17 of the key human power section 12, the kana/kanji conversion section 54 converts the key human power character symbol stored in the conversion data storage section 52. This is to search for the kanji corresponding to the [kana j character] in the data. At this time, kanji are searched in the order of fixed phrases → juku → single kanji, and the searched kanji are stored in the candidate kanji storage unit 55, Candidate kanji memory Fg! It is read out from I55 and displayed on the display section 13. Here, I guess the above/
In the case where the kanji searched by the kanji conversion unit 54 has a plurality of homophones or homonyms, the display unit 13
If there are more than the display limit number (for example, 8 characters for the bottom line), the next candidate signal is input from the control section 51 by operating the next candidate key 18 of the key human power section 12, and other undisplayed items are displayed. Candidate kanji for minutes 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 converted data storage section 52, character symbol data that does not require Kanji conversion is also transferred to and stored in the text data storage section 56. That is, the text data storage section 56 stores the branch information created by the manual operation of the key ALL12.

Kana/kanji converted kanji, unconverted kana, katakana,
Stored as document character data consisting of 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. The character is called as an actual character via the character generator 59 and output to the thermal head drive circuit 57. The encoder pulse from the encoder 41 is input to the thermal head drive circuit 57 when the print mode signal and the print key signal are output from the control unit 51, and the encoder pulse is input via the printing character generator 59 in synchronization with this encoder pulse. The character data to be
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.
4 dots (full width), the above-mentioned 1 line means 1/24 line of 1 character.

Further, a register 60 for controlling the print length when printing created document data is connected to the control unit 51.
0 is connected to an arithmetic and judgment unit 61 having a comparison function. The register EN of the print length control register 60 contains the one-line print quality specified by the operation of the front print length key 15b, and the register ADR8 contains the read address of the document data in the text data storage section 56. , register A stores the character data to be stored at the address specified by ADR8, register B stores the length in the printing direction of the character data stored in register A, and register K stores the length of the character data stored in register A in the printing direction. Digit pitch data specified by 15G is stored.

The calculation and judgment unit 61 registers the register LE every time one character data is read out during printing from the text data storage unit 56.
Subtract the one-line printing length set in N from the above character printing length B and digit pitch, and calculate the remaining one-line printing length as a new LE.
Also, the comparison data of 8 or K with respect to LEN is output to the control section 51. Here, based on the above calculation and comparison data from the judgment unit 61, it is determined that the remaining distance 11LEN for subtracting the fixed print length is less than the print direction length B of the character data to be printed next or the prespecified digit pitch. When this is indicated, the control unit 51 outputs a print stop command and closes the encoder pulse supply gate (AND gate AND) to the thermal head drive circuit 57.

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 operates the keypad section 12 of the device main body 10 to sequentially input desired characters, symbols, etc.

First, when the character/symbol input key 14 and the function key 15 are operated to enter the document information to be created, the input document data is sequentially transferred to the conversion data storage section 52 whose address is specified via the lbl1m section 51. be done. at the same time,
The input document data is displayed on the display section 13 via the display character generator 58 and the display RAM 53. After inputting kana of the desired document, when the kana/kanji conversion key 17 is operated, the kana/kanji conversion section 5
At step 4, kana/kanji conversion processing is performed in the order of fixed phrases, compound words, and single kanji characters from the beginning of the input characters.

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, when the user operates the kanji selection keys 198 to 19f to specify a desired kanji among the homophone candidate kanji, the selection signal is output to the candidate kanji storage section 55, and the kana character to be converted is converted into kanji. At the same time, the next kana character to be converted is indicated on the cursor. In this case, the kanji data after conversion is
It is transferred to and stored in the document data storage section 56. After this,
The kanji selection process is repeated again in the same manner as above to perform kana/kanji conversion.

Here, if the reading of a kana character that matches a kanji that does not require conversion is shown, operate the cursor keys 16 to indicate the desired kana character, and select the reading that matches the reading. iiDisplay the kanji. 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/81 [character 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 the kana/kanji conversion are sequentially transferred from the candidate kanji storage section 55 to the text data storage section 56, but the characters, g, etc. that do not require the kana/kanji conversion are , by operating the illuminance (no conversion) key of the function keys 15, the text data storage unit 5 can be stored as the stored data in the converted 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 print mode PR position. By switching the mode changeover switch 11, the control unit 51 is set to print mode, and the thermal head drive circuit 5
7 is in a state where encoder pulses from the encoder 41 are input. Here, in particular, if the -line print length and digit pitch are not specified, the one-line print length for the register LEN is set to infinity, and the digit pitch for the register K is set to a predetermined value.

In this state, the user brings the print head section HA into contact with the recording paper A, and moves the apparatus main body 10 in the direction of arrow X while pressing the print key 20, as shown in FIG. As the device main body 10 moves, the rubber rollers 31 and 32 rotate, and the rotation is transmitted to gears 37a and 37b in FIG. 2. As the gear 37b rotates, the encoder disk 38 rotates, and the rotation of the encoder disk 38 causes the LED 39 to be drawn from the slit 38a.

The light sent to the photosensor 40 via 38b, . . . is controlled intermittently, and the photosensor 40 outputs a pulse signal. The pulse signal output from the photosensor 4o becomes the output of the encoder 41, and is sent to the control unit 51 and the thermal head drive circuit 57 as a transfer 1JfA detection signal for the apparatus main body 11. Further, the rotation of the rubber roller 31 is controlled by a one-way clutch 34 and a gear 3.
5a.

35b to the ribbon take-up shaft 36, and roughly the take-up spool 2 in the ink ribbon cassette 22.
This will be communicated to 3b. 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, as the apparatus main body 10 moves, the ribbon winding shaft 36 rotates in accordance with the moving layer of the apparatus main body 10 so as to prevent soaking between the recording paper A and the ink ribbon 24. , the ink ribbon 24 is lightly pressed against the recording paper A by the thermal bed 27, which has constant downward printing pressure due to the spring 28b.

On the other hand, the movement amount detection signal output from the photosensor 40 is sent to the control section 51 and the thermal head drive circuit 57 as an output signal of the encoder 41, as described above. Then, the control unit 51 sequentially specifies the memory addresses of the text data storage unit 56 in accordance with the movement amount detection signal from the encoder 41, reads out the document data stored therein, and transfers this document data to the printing character generator. 59 and output to the thermal head drive circuit 57 as individual character data. The thermal head drive circuit 57 drives the thermal head 27 in synchronization with the movement amount detection signal from the encoder 41, that is, in synchronization with the timing of reading document data by the control section 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, as the apparatus main body 10 moves, the unused portion of the ink ribbon 24 is fed out from the feeding spool 23a of the ink ribbon cassette 22, and the used portion after being thermally transferred by the thermal head 27 is transferred to the same cassette. The film is sequentially wound onto a take-up spool 23b in 22. By moving the device main body 10 as described above,
The created document data stored in the text data storage section 56 is sequentially printed on the recording sheet A. In this case, each time one character data is read from the text data storage section 56, the LE
The printing length B and digit pitch of the character data are subtracted from N, but here, since LEN is set to infinity, the value will not fall below B or K, and A print stop command is not output until there is no more document data. In other words, the created document data will be continuously printed out as long as the main body 10 continues printing movement. Therefore, the small device body 1
0 moves itself to print on the recording paper A, so regardless of the size of the recording paper A, as long as the minimum printing range of the created document data is secured, it can be printed on any recording paper A, for example, a bound notebook. It can also be printed.

Next, the printing operation when the -line printing length and digit pitch are arbitrarily specified will be explained with reference to the flowchart of FIG. 4.

For example, after the document creation process in the word processor mode WP, the print length for one line corresponding to the width of the recording paper A is specified by operating the print length key 15b, and the desired digit pitch is specified by the digit pitch key 15c. Operate and specify. When the operation mode is set to print mode PR by the mode changeover switch 12, the document data is printed according to the specified line print length as described below.

That is, first, the specified one-line print length is registered in EN, the digit pitch is in register K, and then in register AD.
The reading start address in the text data storage section 56 is set in R8 (step S1). In this way, when the initial setting of each data is completed and the print key 20 is pressed to start the print movement operation in the X direction of the main body 10, the text data storage section is stored in the register A at the address specified by the above ADR8. The character data in 56 is set, and then the length in the print direction of the character data set in register 8 is set in register B (steps 82 to S4).

Here, if it is determined based on the 8I calculation and the comparison data from the judgment unit 61 that the printing direction length B of the character data set in the register A is less than or equal to the printing length of one line LEN, the designated printing Assuming that new character data can be set in the register A, the character data in the register A is transferred to the thermal head drive circuit 57 via the printing character generator 59, and is printed out on the recording paper A by the thermal head 27. (Step S5, 86). Then, after updating the read address for the text data storage unit 56 in the register ADR3, the remaining one-line printing length is obtained by subtracting the printing length B of the printed character data from the initially set one-line printing length EN. New L
Set as EN (steps 87 and 88). Here, based on the comparison data from the calculation and judgment section 61, the remaining one-line printing length L determined in the above step S8 is determined.
If EN is determined to be longer than the specified digit pitch,
Furthermore, the remaining one-line printing length obtained by subtracting the digits and the touch K from the current one-line printing length LEN is set as a new LEN (step S9.510). In this way, first, after going through the processes of steps 82 to 310, one character's worth of data is read out from the text data storage section 56 and printed out. In this case, the remaining print length of one line currently set in the register LEN is the value obtained by subtracting the print length B of the character data printed out in step S6 and the digit pitch.

After that, while repeating the printing process for each character of the document data in steps 82 to 810, in step S5 (No), that is, the current remaining print length LEN is longer than the print length of the character data to be printed next. If it is determined that it is shorter, or (No) in step S9, that is, it is determined that the current remaining one-line print length LEN is shorter than the specified digit pitch, the amount of data corresponding to the pre-specified one-line print length is This means that the document data has been read out from the text data storage section 56 and printed out, and at this time, the control section 51
outputs a printing stop command, and the thermal head drive circuit 5
The supply of encoder pulses to 7 is blocked to stop its printing operation (step $11).

That is, by repeating the processes in steps 82 to S11 above, for example, the fifth
The document data stored as shown in the figure is shown in FIG. 6(A).
Alternatively, as shown in FIG. 6(B), the lines are divided into predetermined print lengths and are sequentially printed out. In other words, after the first printing operation is stopped, press the print key 20 again and press the printer main body 1 from the left edge of the recording paper.
By repeating the movement operation of 0, the created Buntomi data can be easily printed out sequentially to the second line, third line, etc., with the print length of each print line being the same.

Next, the display section 1 according to the print operation of the document data is displayed.
The display state of No. 3 will be explained.

First, in the initial state of the print mode when the mode changeover switch 11 is switched, the displayable range of the created document data stored in the text data storage als 56 is displayed from the beginning. Then, when printing is started, the text data corresponding to the characters and symbols actually thermally transferred printed on the recording paper A disappear from the display section 13, and are replaced by
The document data in the text data storage section 56 that follows the document data that has been displayed so far is shifted and displayed. After this 1. When printing of the entire text data stored in the text data storage section 56 is completed, the display section 13 becomes blank. In other words, the user prints the sentence 1 data to be printed.
The printing process is performed by moving the apparatus body 10 while checking the display state of the display section 13. In this way, once the entire data has been printed, if you want to print the same data again, press the R8 (restart) key among the function keys 15 to return to the initial state of the print mode. return.

Therefore, according to the printing device configured as described above, it is not only possible to print on recording paper of a specified size or larger, bound notebooks, etc., but also the print length can be extended to one line depending on the width of the recording paper. can be specified arbitrarily, and it is possible to easily obtain a print format in which the print length of each print line is the same.

[Effects of the Invention] As described above, according to the present invention, there is provided a means for printing input and stored data on a recording paper by moving the main body of the apparatus, and the printing length for one line is specified, and the above-mentioned printing is performed. When printing stored data using the device, the printing operation is stopped when the specified print length is reached, so it can be used for bound notebooks or recording paper larger than the specified size, for example. To provide a small-sized character printing device which can easily perform printing processing in which print lengths of each line are made uniform without causing missing or overlapping printed characters by specifying an arbitrary printing length.
