Abstract

PURPOSE:To permit expanded letters over plural lines to be printed even when printing is made for one line each for a document by a method in which the amount of papers to be sent is varied for cases where expanded letters are present or not, vertical spacing amounts of lines are automatically determined even when letters to be hardly printed on one line are present, and the letter are formed over plural lines. CONSTITUTION:RAM 3 has a working area where compressed Chinese character pattern information stored in ROM 2 is developed to the dot image of the character or variously processed and also various flags, counter STPC, and flag FLG are stored, where information on document to be prepared and moving sentence, and information on tabulation, user dictionary, and foreign letters are stored. When one-line printing is indicted by a keyboard 4, document information in RAM 3 is investigated, and when expanded letters are present,flag FLG is turned ON. One-line printing is made by a thermal printer 13, and when the printing is ended, the flag FLG is checked. When the flag FLG is ON, or when expanded letters are present, doe papers for the thermal head 14 are sent out and the expanded letters are printed over plural lines.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document information processing apparatus such as a word processor that creates and prints document information.

[Prior Art] In recent years, the buying and selling of functions of word processors (hereinafter referred to as word processors) and price reductions have proceeded at a remarkable pace.
In the past, high-priced machines were only used exclusively by specialized operators, but with the spread of low-cost word processors for personal use, even non-specialists can easily use them to create personal information. It has become. In addition, these word processors used to be good document formatters for the purpose of formatting sharpened documents, but now they can be used as document creation machines in the true sense of the word, allowing you to input documents while creating them. There is a growing demand for Ia capabilities. In other words, it is like writing on a word processor using a keyboard instead of writing on paper using lead 1.

There are two types of printing methods for this low-cost word processor for personal use: batch printing and single line printing. The song title is created by inputting and editing document information into a word processor, and after the document is created, one page of the document is printed all at once.The latter method is, for example, the title of a single cassette label. This function is used when you want to print only - lines, such as , and is a method that prints one line only on the line where the current cursor is located.

The latter can also be used to create, edit, and print a document line by line, allowing you to check the entire document on paper, which helps eliminate the drawback that it is difficult to see the current cursor position in the entire document due to the small display. It is what it is.

Furthermore, word processors have a function of enlarged characters for emphasizing only certain characters in a document, but with this enlarged character, one character may extend over multiple lines.

For example, let's talk about creating and printing text one line at a time while using these enlarged characters. Normally, when printing one line, after printing one line, the paper is fed by the appropriate line pitch using the foot motor. The head position is at the beginning of the next line. However, with this method, for example, 4
When printing double characters, as shown in Figure 2 (b), when printing the first line, first print only the upper half of the 4 times magnification, and when printing the lower half on the second line, change the line spacing. I will send it, so
The top and bottom of quadruple characters are no longer connected.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned conventional example. When printing text line by line, for example, it is difficult to process characters that span multiple lines, such as enlarged characters. The aim is to provide an easy-to-use document information processing device that changes the paper feed amount when there are enlarged characters and when there are no enlarged characters, and automatically adjusts the line feed amount even when there are characters that cannot be printed in one line. is determined, and the character is formed over multiple lines.

As a means to solve this problem, for example, the word processor of the embodiment shown in FIG. 1 has a RAM 3 as a document memory,
It includes a keyboard section 4 as an instruction means for instructing printing, a thermal printer 13 as a printing means, and a flag FLG indicating that enlarged characters in the RAM 3 are present.

[Operation J] In the configuration shown in FIG. 1, when one line printing is instructed from the keyboard unit 4, the document information in the RAM 3 is checked, and if there are enlarged characters, the flag FLG is turned on. One line is printed by the thermal printer 13, and when the one line print is HT, the flag FLG is checked. When the flag FLG is on, that is, when enlarged characters exist, the thermal head 1
Enlarged characters are printed by feeding the paper by 4 dots and printing across multiple lines.

Embodiment J Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Description of the schematic block diagram of a word processor (FIG. 1) 1 FIG. 1 is a schematic block diagram of a word processor according to an embodiment of the present invention.

1 is a CPU that controls the entire device, 2 is a ROM that controls the CPU
It is divided into a program section that stores the control program of U1 and a data section. The program section stores microinstruction information for sequentially controlling the CPU. Additionally, the data includes various kanji patterns, compound word document information, and the like.

3 is readable/writable RAM access memory (RAM)
There is a working area where the compressed kanji pattern information stored in the ROMZ is expanded into character dot images, various calculation processes are performed, and various flags are stored, such as counter 5TPC and flag FLG, which will be described later. be. It also stores document information to be created, moving phrase information, tab information, user dictionary, external character information, etc.

3 is the keyboard part, character keys for inputting characters,
Conversion keys for kanji conversion, edit keys for editing documents, cursor keys, print control keys, etc. are arranged, and the keyboard controller 5 keys scan signal 2
2, a key signal 23 corresponding to the pressed key is sent to the keyboard controller 5. Reference numeral 6 denotes a liquid crystal display, which displays a portion of the document being created, and allows the user to create and edit the document while viewing this display. The liquid crystal display section 6 has a dot matrix configuration and is driven by a common driver 7 and a segment driver 88 based on control information from a liquid crystal controller 9. or,
The display RAM 10 stores data such as characters and numbers displayed on the liquid crystal display section 6.

Reference numeral 13 denotes a thermal printer, which includes a 16-dot thermal head 13, a carrier motor 18 that drives the carrier on which the thermal head 13 is mounted, a foot motor 19 that moves the paper feet, an up-down motor 19 that moves the head up and down, and a carrier. A home position detection switch 21 is provided for detecting the home position of the vehicle.

A thermal head drive signal 24 corresponding to print data is output from the printer interface 11, and the thermal head is driven via the head driver 12 to generate heat.

As a result, the ink on the transfer tape facing the head is melted and further applied onto the facing paper surface, forming dots of characters to be printed on the paper surface.

Furthermore, the carrier motor drive signal 25 from the printer interface 11 excites and rotates each phase of the carrier motor 18 via the carrier motor driver 15, thereby moving the thermal head 13 to the next dot printing position. After printing for one line is repeated in the same manner, the thermal head 14 is separated from the paper by the up-down motor 20, and the opposite phase of the carrier motor 18 is excited to move the carrier in the opposite direction and return it to the home position.

A feed motor drive signal 26 from the printer interface 11 feeds the paper by rotating each phase of the feed motor via the feed motor driver 16. Reference numeral 20 is an up-down motor; The motor driver 17 changes the rotational direction of the up-down motor 20 by reversing the polarity of the voltage applied to both ends of the up-down motor 20 in response to the signal 27 and the head down signal 28, thereby causing the thermal head 14 on the carrier to stick to the paper surface. It is something that can be moved (down) or released (up).

Reference numeral 21 denotes a home position detection switch, and the state j5 of this switch 21 is always checked at the time of reset and at the time of power recovery (ON time) to confirm that the carrier is at the home position. Then, correction is made when the position ε of the carrier shifts due to vibrations, paper jams, etc.

[Explanation of document information (Figures 3) to 5) Figure 3 is a state diagram when the document in Figure 2 is stored in the document area of RAM, and each address contains a 2-byte character. In the 0 diagram where the code is stored.

→, 2, and ↑ indicate that quadruple characters are stored.

In FIG. 4, a NULL code (N), a line feed code Q, etc. are added to the document in FIG. 3 to make it easier to print.

[Explanation of one-line printing operation (Figures 1 and 5)] Figure 5 shows R
This is a flowchart of a CPUI one-line printing control program stored in OM2.

First, in step S1, a document stored in the RAM 3 is preprocessed. This is a process for converting a document as shown in FIG. 3 into a document format as shown in FIG.

In step S2, the character code of the print character string is developed into a bit pattern based on the character pattern in the ROM2. Here, the NULL code is not converted as is, and “→”
A quadruple character indicated by a symbol such as , etc. is developed into a character pattern of four times the size.

In step S3, it is checked whether the line contains the ゛°→ barcode, and if so, Stella 7'S4
, and turn on the flag FLG in RAM3. °゛→
If there is no code ``''→''', the process advances to step S5 and the flag FLG is turned off.

In step S6, the counter 5TPC for counting the feed amount of the carrier motor 18 in the RAM 3 is cleared to 0, and in step S7, an excitation signal for the carrier motor 18 is output to rotate the carrier motor 18 by one step. In step S8, the counter 5TPC is incremented, and in step S9, it is checked whether the corresponding code is a NULL code. If it is a NULL code, the process returns to step S7 and the same operation as described above is performed.

In step S10, the head town signal 28 is output,
The thermal head 14 is turned on, and in step S11, a dot pattern is output to the head driver 12 to print one column of 7ttL through the thermal head 14.

In step 312, it is checked whether it is a line feed code indicating the end of one line of the document, and if it is not a line feed code, step S7
Return to , and perform the above operation again.

If it is a line feed code, the process proceeds to step S13, where the head-up signal 27 is output, the carrier motor 18 is reversed in step 114, and the counter 5TPC, which counts the feed of the carrier motor, is decremented in step S15. Check whether 5TPC has become O in step 516, and
If not, the process returns to step SL4 and the carrier motor 18 is reversed.

When the carrier motor 18 is reversed and the carrier returns to its original position, the process advances to step S17 to check whether the flag FLG is on. When the flag FLG is off, that is, when the quadruple character does not exist in the current line, the process advances to step 318 and the value is set to 1.
Feed the paper by the line spacing. On the other hand, when the flag FLG is on, the process advances to step S19, where the paper is fed by 16 dots corresponding to the number of dots in the thermal head 14, and then the process returns to step S5, where the same operations as described above are performed to form enlarged characters.

As described above, according to this embodiment, when creating and printing a document while creating sentences line by line, even if there are enlarged characters, the enlarged characters can be created without being interrupted in the middle. Become.

Furthermore, in this embodiment, quadruple characters have been described, but for example, enlarged characters of octuple characters, 16 times characters, etc. may also be used, and as long as one character spans multiple lines, it is not limited to enlarged characters. Of course.

In short, various applications are possible without departing from the spirit of the present invention.

[Effects of the Invention] As described above, according to the present invention, even when printing a document line by line, it is possible to print, for example, enlarged characters over multiple lines.
