Further, the word processor main body 10 is equipped with a thermal transfer printer 21 behind the display section 13. Here, the print data bus for the printer 21 is internally 2
It is separated into systems and connected to the manual printer 11 via a plug 22 and a pass line 23.

On the other hand, on the lower surface of the manual printer 11, there is a print head section HA, which is equipped with a line-type thermal head of, for example, 96 dots per line (24 x 24 dots of full-width printing), with the line direction facing the width direction of the main body of the printer 11. provided.

The character/symbol key 14 in the word processor main body 10 is used to manually input the created document or the function key 1.
Function keys 15 are used to input alphanumeric characters, symbols, etc. in conjunction with 5, and the function keys 15 include, for example, execution keys for starting and ending document input or delimiting the designated range of movement on the document using cursor k. , keys for specifying various functions necessary for document creation/printing using the character/symbol key 14 are arranged, such as insert, delete, and shift keys. The characters and symbols input using the character ψ 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 unit 13 together with the input document and symbols in the left and right direction, and by moving this cursor, an input position, a functional range, etc. are specified. The Kana/Kanji conversion key 17 is used to convert a document entered into Kana using the character/symbol entry key 14 into Kana and Kanji for each fixed phrase, compound word, or single kanji. A predetermined number of the previous 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 kanji selection key 19.

That is, in the document creation mode, a desired document is created by repeating the manual key operations for characters and symbols, the kana/kanji conversion operation, and the kanji selection operation. When printing a document created manually, after specifying the print mode, the user sets the recording paper A1 in the printer 21 and operates the print key 20. In this case, printer 2
The created document is printed on recording paper A1 of a specified size that conforms to 1.

On the other hand, when the manual printer 11 is moved in the direction indicated by the arrow X on another recording paper A2, the created document is printed on the desired recording paper A2. In this case, for example, due to a user's operational error, the manual printer 11 may be moved in the normal printing direction
If an attempt is made to move it in the opposite direction, an internal movement prevention mechanism will be activated to prevent printing errors from occurring.

FIG. 2 shows a print unit 25 constructed within the manual printer 11, and an ink ribbon cassette (not shown) is attached to and removed from the print unit 25 with high accuracy.

1. A ribbon loading notch 26 is formed in the printing head section HA of the printing section 25, and a thermal head is installed in the center of the notch 26 with its head surface slightly protruding from the bottom surface of the printer 11 main body. 27 is placed. This thermal head 27 is mounted so that it can be moved slightly up and down by a slide stay 28a that is installed upright on a member 28, and the printing is always downward due to the action of a spring that is integrally wound around this stay 28a. Pressure is maintained.

Furthermore, the ribbon loading notch 26 is provided on the lower surface side of the main body of the printer 11 where the thermal head 27 is arranged.
Two large and small openings 29 and 30 are formed on both sides, and rubber rollers 31 and 32 are arranged in each of the openings 29 and 30, respectively. These rubber rollers 31 and 32 are used to hold the printer 11 during printing operations.
When the main body is moved in the direction indicated by arrow X, the recording paper A
A gear 33 is coaxially fixed to one side of one rubber roller 31. This gear 33 is formed to have a smaller diameter than the rubber roller 31.
．． It is connected to the winding gear 36 via 35a and 35b. This winding gear 36 has a ribbon winding shaft 3 coaxially connected thereto.
A stopper arm 38 that presses against the winding gear 36 is attached to the base of the winding shaft 37. This soot brim arm 38 rotates in the rotation direction of the gear 36 due to pressure contact with the winding gear 36, and a stopper gear 39 that fits into the winding gear 36 is attached to the tip of this arm 38. provided. Further, an arm stopper 40 is provided in the rotating direction of the arm 38 corresponding to the winding rotation direction of the winding gear 36. Here, when the winding gear 36 rotates in the ribbon winding direction,
The stopper arm 38 rotates to the arm stopper 40 and stops, and when it rotates in the opposite direction, the arm 38 rotates to the stopper gear 3 at its tip, as shown by arrow g.
9 is rotated until it fits into the gear 35b and then stops. In other words, the gears 35b and 36, the stopper arm 38, the stopper gear 39, and the arm stopper 40 constitute a reverse rotation prevention mechanism.

On the other hand, an encoder disk 41 is connected to the gear 35a. Here, the rotation of the rubber roller 31 is indicated by the arrow a
As shown by -f, the configuration is such that it is transmitted to the ribbon winding shaft 37 and the encoder disk 41. This encoder disk 41 has a plurality of sleeves) 41a, 41b, .
... are formed radially at regular intervals, and an LED 42 and a photosensor 43 are arranged adjacent to each other at two positions facing each other with the slit forming portion of the encoder disk 41 interposed therebetween. In this case, the projected light from the LED 42 is transmitted through the slit 41 of the encoder disk 41.
a, 41b, . . . and enters the photosensor 43. In other words, the encoder 44 includes the encoder disk 41, the LED 42, the photosensor 43, and the like.

An ink ribbon cassette (not shown) is attached to the print section 25 using the ribbon winding shaft 37 as a support shaft. In this case, the thermal transfer ink ribbon exposed in a part of the lower end of the ribbon cassette is set in contact with the head surface of the thermal head 27 disposed in the ribbon loading notch 26 of the print section 25.

FIG. 3 shows the configuration of an electronic circuit incorporated in the word processor main body 10 and the manual printer 11. In the figure, 51 is a control section, and this control section 51 includes:
Various key manual operation signals from the key manual unit 12 are input. In response to various key operation signals from the key human power section 12, the control section 51 controls the conversion data (key human power data) storage section 52, display RAM 53, kana/kanji conversion section 54, candidate kanji storage section 55, It controls the text data storage section 56, thermal head drive circuit 57, etc.

The conversion data storage unit 52 sequentially stores character/symbol data such as “kana” and “symbol” manually entered by operating the character/symbol input keys 14 and the function keys 15 from the key input unit 12. 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 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 a search for kanji that corresponds to the ``kana'' character in the data.
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 kana/kanji conversion section 54 has a plurality of homophones or homophones, and if there are more than the display limit number of the display section 13, the key human power section By manipulating the next candidate signal from the control section 51 by operating the next candidate key 18 of 12, the candidate Chinese characters of the other undisplayed bones are read out and sequentially replaced and displayed. In this candidate kanji storage unit 55,
When a selection signal from the control section 51 is input by operating the kanji selection key 19 of the key input section 12, the selected kanji data is output to the text data storage section 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 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, kana without conversion, 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. The character is called as an actual character via the character generator 59 and output to the thermal head drive circuit 57 of the printer 21 . Here, the thermal head 57a and platen 57b are connected to the carriage and platen control section 57c.
The built-in printer 21 performs printing.

On the other hand, the manual printer 11 is equipped with a printer control section 6o, and the printer control section 6o receives print data and print control signals from the word processor main body 1o, and encoder pulses (movement of the manual printer 11) from an encoder 44. quantity detection signal) is given. The print data given to the printer control unit 6o is transmitted to the magnification determination unit 61.
The set magnification is determined in step 1, and the magnification data is set in the print magnification register 62. Printer control unit 6
0 enlarges the input print character data according to the print magnification set in the print magnification register 62,
The data is transferred to the print data buffer 63. The print character data applied to the print data buffer 763 is output to the thermal head 27 via the head drive circuit 64 and printed on the recording paper A2. In this case, the head drive control section 64
In this case, the encoder pulse from the encoder 44 is manually inputted, and in synchronization with the encoder pulse, the character data inputted from the printing character generator 59 via the printer control unit 60 and the print data buffer 763 is converted into one character data.
It is transferred to the thermal head 27 line by line. Here, the print quality by the thermal head 27 is, for example, 24×24
Since it is a dot (full-width), the above-mentioned one line means 1/24th line of one character in the case of a full-width character.

It should be noted that the print data handled in the text data storage section 56 includes 8 pieces of information indicating the magnification, vertical writing, and horizontal writing.
It has a 3-byte configuration consisting of bits and 16 bits indicating character information, and if the magnification information of the print data exceeds 4x, the magnification judgment unit 61 selects the print magnification register 6.
Forcibly set the setting print magnification in 2 to 4x square,
It is adapted to the size of the thermal head 27 (96 dots).

Here, the double-angle processing according to the print magnification set in the print magnification register 62 in the printer control unit 60 is performed by repeating the same print dot the same number of times as the multiple of the two-leg setting magnification and transferring it to the print data buffer 63. It will be done.

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

First, to create a desired document, the word processor main body 10 is set to document creation mode.

Here, the user operates the key manual section 12 of the word processor main body 10 to input desired characters, symbols, etc. one by one.

First, when the character/symbol key 14 and the function key 15 are operated to manually 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 control section 51. be done. At the same time, the input document data is displayed on the display unit 13 via the display 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 kana/kanji in the order of fixed phrases → idioms → single kanji from the beginning of the input characters. It is done.

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 key 19 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. , the next kana character to be converted is indicated at 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/kanji conversion.

Here, when the reading of a kana character that matches a kanji that does not require conversion is shown, the cursor key 16 is operated to indicate the desired kana character, and candidate kanji that match the reading are displayed. 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 51 outputs a next candidate signal to the candidate kanji storage section 55. 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. In addition, above 1
If the desired kanji is not displayed after the next 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/kanji conversion are sequentially transferred from the candidate kanji storage section 55 to the text data storage section 56, but characters, symbols, etc. that do not require kana/kanji conversion are By operating the oven change (no conversion) key of the function keys 15, the data stored in the converted data storage section 52 is transferred to the text data storage section 56 as is. 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 manually created using the key as described above. When printing document data, the word processor main body 10 is set to print mode. Then, the text data storage section 56 enters the reading state, and the thermal head drive circuit 57 enters the control section 51.
The printer waits for input of a print control signal from the printer. In this state, when a print control signal is manually input to the thermal head drive circuit 57, the control unit 51 sequentially specifies the memory address of the text data storage unit 56 according to the print control signal, and the data stored therein is sequentially specified. The document data is read and outputted to the thermal head drive circuit 57 as individual character data through a printing character generator 59. The thermal head drive circuit 57 drives the thermal head 57a in synchronization with the movement of the carriage by the carriage and platen control section 57c, which operates in response to the print control signal. By driving this thermal head 57a, document data is printed by thermal transfer onto the recording paper A1 set on the platen 57b.

When the manual printer 11 prints on the desired recording paper A2, its head drive control section 64 waits for input of encoder pulses from the encoder pulse generating section 44a of the encoder 44. In this state, the user moves the print head section HA onto the recording paper A as shown in FIG.
2 and move the main body of the manual printer 11 in the direction of arrow X.

As the main body of the printer 11 moves, the rubber rollers 31 and 32 in FIG. 2 rotate, and this rotation causes the gears 34 and 35 to rotate.
a, 35b. As the gear 35a rotates, the encoder disk 41 rotates, and the rotation of the encoder disk 41 causes the LED 42 to be exposed to the slit 41a.

The light sent to the corresponding photosensor 43 via 41b, . . . is controlled intermittently. Thereby, the pulse signal output from the encoder pulse generating section 44a is sent to the printer control section 60 and the head drive control section 64 as a movement amount detection signal with respect to the main body of the printer 11. Also,
The rotation of the rubber roller 31 is transmitted to the winding gear 36 and the ribbon winding shaft 36, and further to a ribbon winding Lisbourg in an ink ribbon cassette (not shown). As a result, as the printer 11 main body moves, the ribbon winding shaft 37 rotates in accordance with the amount of movement of the printer 11 main body so as to prevent slipping between the recording paper A2 and the ink ribbon. - The ribbon is lightly pressed against the recording paper A2 by the thermal head 27 which constantly applies downward printing pressure due to the spring of the slide stay 28a.

Here, when the main body of the manual printer 11 moves for printing in the X direction, the take-up gear 36 is in a normal rotation state, and the stopper arm 38 is held in contact with the arm stopper 4o.

On the other hand, the movement amount detection signal output from the encoder pulse generating section 44a is sent to the printer control section 60 and the head drive control section 64 as an output signal of the encoder 44, as described above. Then, the printer control unit 60 sequentially specifies the memory addresses of the text data storage unit 56 in accordance with the movement amount detection signal from the encoder 44, reads out the document data stored therein, and converts this document data into printing characters. It is output to the print data buffer 63 as individual character data through the generator 59. In this case, each print character data given to the print data buffer 63 has its print magnification determined by the magnification determination unit 6.
1, and enlargement processing is performed according to the magnification set in the print magnification register 62. Then, the head drive control section 64 reads the print character data in the print data buffer 63 and drives the thermal head 27 in synchronization with the movement amount detection signal from the encoder 44 . By driving this thermal head 27, document data is thermally transferred onto the recording paper A2 via an ink ribbon of an ink ribbon cassette (not shown). By moving the manual printer 11 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 A2. In this case, manual printer 11
Since the thermal head 27 in is composed of 96 dots,
When the full-width printing quality is 24×24 dots, enlarged printing up to 4 times the width is possible.

Also, the small printer 11 itself is moved to print the recording paper A2.
Since printing is performed on the top, there is no need for a mechanism for moving the thermal head 27 in the sub-scanning direction and a mechanism for feeding the recording paper A2, and no mechanism drive motor is used, so the power consumption associated with printing is extremely low. Become.

Next, the printing operation of document data in the manual printer 11 will be described in detail with reference to the flowchart shown in FIG.

First, when print data is given from the word processor main body 1o, its print magnification data is read, and the set print magnification is determined by the magnification determining section 61 (step Sl
, S2). Then, the horizontal magnification data is first set in the horizontal magnification register in the print magnification register 62, and then it is determined whether the vertical magnification data exceeds 4 times the width, that is, whether it is outside the printable range by the thermal head 27. (Steps S3 and S4). Here, if the printing vertical magnification of the print data is 4x or less, the vertical magnification data is also set in the vertical magnification register in the printing magnification register 62 (steps S4 and S5).

On the other hand, if the print vertical magnification of the print data exceeds 4x and is determined to be outside the printable range by the thermal head 27, the magnification determining unit 61 forcibly sets the vertical magnification register of the print magnification register 62. Set the quadruple angle (steps S4→S6). Then, the print control section 60 displays a message on the display section 13 of the word processor main body 10, as shown in FIG. Displays a message indicating that the printout will be reduced to 4 times the size. (
Step S7).

When the vertical and horizontal magnification data of the print data are set in the print magnification register 62 in this way, the print character generator 59 of the word processor main body 10
The printed character pattern is sent to the printer control unit 60 via
is read into the print data buffer 63, enlarged by 6 times horizontally and 4 times vertically, for example, and output to the print data buffer 63 (step S8.S
9). As a result, as shown in FIG. 6, when the encoder pulse corresponding to the movement operation in the X direction on the recording paper A2 of the manual printer 11 is supplied to the head drive control section 64, it is stored in the print data buffer 63. The printed character data is sequentially printed line by line by the thermal head 27 via the head drive control section 64. in this case,
Print data set to a vertical magnification of more than 4x when creating a document will be forcibly compressed to 4x and printed, but enlarged characters of 4x or less will be printed at the originally set print magnification. will be done.

FIG. 7 shows a state where enlarged characters printed by the manual printer 11 are printed by the built-in printer 21 of the word processor main body 10. In this case, the enlarged characters are printed according to the printing magnification set at the time of document creation. Said fifth
The same image as the image pattern of the display section 13 shown in the figure will be printed out.

Next, as described above, in a printing device that can perform printing processing by manual operation, a printing error prevention operation is performed when the user attempts to move the manual printer 11 in the opposite direction to the X direction due to an operational error. I will explain about it.

For example, if the printer 11 is moved backwards on recording paper A2,
The reverse movement of the rubber roller 31 is caused by gears 34° 35a, 35b.
It is also transmitted to the winding gear 36 via. This winding gear 3
6 reverses, the stopper arm 3
8 rotates and stops until a stopper gear 39 provided at its tip engages with the gear 35b. At this time, gear 3
5b and the winding gear 36 are prevented from rotating in a state where the stopper gear 39 is retracted from each other. This results in
The reverse movement of the rubber roller 31, the ribbon winding shaft 37, and the encoder disk 41 is also prevented, and not only the operation of moving the manual printer 11 in the opposite direction, but also the feeding operation of the ink ribbon (not shown) and the output operation of encoder pulses are prevented. As a result, printing errors caused by operating the manual printer 11 in the opposite direction can be reliably prevented.

Therefore, according to the printing device with the above configuration, by configuring the manual printer 11 equipped with the 96-dot thermal head 27, it is possible to print A2 sheets of recording paper other than the specified size, such as bound notebooks, up to 4x height. It is possible to print out enlarged characters.

[Effects of the Invention] As described above, according to the present invention, there is provided a housing, a print head provided in the housing and having a predetermined length, and a housing movement detection means for detecting movement of the housing with respect to recording paper. a head driving means for driving the print head in response to the housing movement detection signal; a print data supply means for supplying print data to the print head; and a direction in which the print data is perpendicular to the movement direction of the print head. If the length of the print data is longer than the head length, the print data is reduced to less than the length of the head. A printing device capable of printing enlarged characters other than double-width characters can be provided.
