Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a document processing device, more specifically, a document processing device that adds modification information to each character in a created or edited document, and makes a predetermined output device correspond to the modification information. The present invention relates to a document processing device that outputs character information that has been created.

[Prior Art] In a conventional document processing device, when it is not desired to output a predetermined character string in a document, attribute information indicating whether or not to print each corresponding character is separately provided. I was dealing with it by letting it happen.

[Problem to be solved by the invention] However, providing this attribute means that the ratio of control system information to the actual printed character code is large, that is, the amount of information for the entire document increases. There was a drawback.

The present invention has been made in view of such problems, and it is an object of the present invention to provide a document processing device that can control whether or not to output a predetermined character string without causing an increase in the amount of information.

[Means for Solving the Problem] A document processing device of the present invention that solves this problem has the configuration shown below. In other words, in a document processing device that adds modification information to each character in a created or edited document and outputs character information corresponding to the modification information to a predetermined output device, characters to which specific modification information has been added are When outputting to the predetermined output device,
It has means for controlling whether or not the character can be output.

[For Use] In the configuration of the present invention, when there is character information to be output to the output device, whether or not to output it is controlled according to the modification information of the character information.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings. Note that the document processing apparatus in the embodiment may be one in which the printing device, display device, etc. are integrated or separated, but the former will be explained here as an example.

FIG. 1 is a schematic functional block diagram of a document processing apparatus in this embodiment.

In the figure, lOO is an underlined character output instruction means for instructing whether or not an underlined character portion in a document to be printed is to be output by a document outputting means 400, which will be described later.

Reference numeral 200 denotes underline determining means for determining whether character data in the document memory DBUF, which will be described later, is underlined when non-output of underlined characters is instructed by the underlined character output instructing means 100.

Reference numeral 300 denotes an underline output means, which outputs only the underlined portion of the underlined character detected by the underline determination means 200 by the document output means 400, which will be described later.

A document output means 400 outputs the contents of the document memory DBIF to the document output device 500.

As can be seen from the above-mentioned configuration outline, in this example,
For underlined strings used in normal document editing,
This controls whether or not to print that character string.

Here, FIG. 2 shows the external appearance of the document processing apparatus in this embodiment, and FIG. 3 shows its main configuration.

In the figure, reference numeral 1 denotes a keyboard for inputting various characters and editing commands, and during printing, it serves as the underlined character output instruction means described above (details will be described later).

2 is a display for displaying document information, and 3 is a unit for driving a floppy disk in which document information and control programs can be stored, and has an eject button, an access lamp, and the like. 4 is a power switch of the device, and 5 is a power plug. 6 is a platen knob, 7 is a device main body, and 8 is a printer section. 9 is a paper release lever, 10 is a paper supporter, 11 is a print density adjustment dial, and 12 is a brightness adjustment dial.

In FIG. 3, 30 is a CPU that controls the entire device.
, 31 is the operation processing procedure of the CPU 31 (section 7.8 to be described later).
The ROM 32, which stores information such as the flowchart shown in the figure, is used as a work area for the CPU 30, and is provided with a data buffer DBUF that stores document information being edited. 33-゛This is a character generator that generates a character pattern corresponding to a character code. Reference numeral 34 denotes a character counter (comprised of RAM or the like) that counts the position or number of output characters when printing out.

FIG. 4 shows the key arrangement of the keyboard 1 in the embodiment.

As shown in the figure, the keyboard 1 includes an ANK key consisting of alphabet, numeric, and kana keys that are included in a typical document processing device, as well as a PRUK key for instructing printing of an underlined character string, and vice versa. In other words, a PRNK key is provided that instructs not to print the underlined character string. The PRUK key and the PRNK key constitute a bobbin thread eastern character output instruction means 100. Other underline determination means 200. Underline output means 300, document output means 4
00 is processed by the CPU 30 and corresponds to the printer unit 8 as the document output device 500.

An overview of the processing of the document processing apparatus of this embodiment with the above-described configuration will be described below.

The document to be edited is stored in the data buffer DBUF in the RAM 32.
It is as shown in the figure.

As shown in the figure, for one character, there is an underline attribute part UL indicating whether the character is underlined, a character code part CHR,
There is (i=1.2...). In the case of Japanese, kanji (
(including hirakana, etc.) are represented in 2 bytes, but strictly speaking, kanji are represented in 15 bits, so the remaining 1 bit is assigned to the underline attribute section, and the remaining 15 bits are assigned to the character code section. Assigned to CHRI. Note that the present invention is not limited to this bit assignment itself;
Any document processing device may be used as long as it performs editing processing by adding information indicating whether or not each character is underlined. In short, it is sufficient if it is possible to tell whether a specific character is underlined or not.

Further, although the explanation is complicated, when the bit of the underline attribute part ULI is 1°, the character code CHRI is assumed to be underlined. Conversely, when the bit is ゛○'', the character is assumed to have no underline.

Now, display the document stored in the data buffer on display 2.
An example of this display is shown in FIG. 6(A). In the illustration, a document consisting of a question sentence and its answer words is displayed, and it can be seen that the answer character string "rBiwagen" is underlined.

When this document is printed by the printer section 8, Fig. 6 (B)
As shown in the figure below, only the underlined character strings are excluded from printing.

Of course, it is also possible to print the underlined character string "Biwa Gen", and these can be switched by pressing either the PRUK key or the PRNK key at the initial stage of the printing process.

The processing procedure of the CPU 30 will be explained according to the flowchart of FIG.

When the device is powered on, the CPU 30 first performs initial settings in step S1 to make various peripheral elements connected to the bus operable.

Thereafter, in step S2, a key input from the keyboard 1 is awaited. When a key is entered manually, the type of input key is determined in step S3, and if it is determined that it is a key related to ANKN- or various editing commands (for example, a cursor key or an underline key), the process proceeds to step S4. Performs input/editing processing, etc. As this manual/editing process employs a known process, a detailed description thereof will be omitted.

If it is determined that the manually pressed key is a key related to a print instruction, the process advances to step S5, and step S6. The process branches to either S7.

If the press of the PRUK key, that is, an underline print instruction is detected, the process advances to step S6, and normal print processing is executed to print as displayed. This normal printing process also employs a known process, and detailed description thereof will be omitted.

On the other hand, if pressing down of PRNKN- is detected, the process advances to step S7 to perform printing rejection processing for the underlined character string.

The contents of the printing process for one line in this rejection printing process (step S7) will be explained according to the flowchart of FIG.

First, in step S14, "°■°" is input as an initial value to the variable N of the character counter 34, and the data tJ L N and CHRN in the document information to be printed are read.Then, the process proceeds to step S14, where the data is read. Daul,
By checking the data, it is determined whether the character of interest is underlined or not. If it is determined that there is no underline, step 31
Proceeding to step 3, the character generator 33 generates a character Bakun for the character code CHR, and outputs it to the printer section 18 to print that character (without underlining).

If it is determined that the character of interest is underlined, that is, its underline attribute part UL is °°1, the process proceeds to step S14, and an underline pattern is added regardless of its character code CHR. By generating a blank pattern and outputting it to a printer section 8, only the underline is printed.

When step S13 or step S14 is executed,
The process proceeds to step S15, where the variable N is set to °゛1''1''.
Increment and in the next step S16, 1
Step S until it is determined that the printing process for the line is completed.
Repeat the process from 12 onwards. Note that to determine whether one line of printing has been completed, the number of characters in one line set at the time of document creation is compared with the value of the variable N, or the number of characters of interest is compared with the value of variable N.
2. The determination shall be made based on whether the code is, for example, a carriage return code.

As described above, according to this embodiment, existing underline attribute information is utilized to exclude specific character strings from being printed, so an increase in the amount of document information is avoided.

Incidentally, in the embodiment, the case where the character code consists of 2 bytes has been described, but the present invention is not limited to this, as it can be similarly applied to a 1-byte character code system.

Further, in the embodiment, a document processing apparatus that prints edited and created documents is used as an example, but the present invention may be applied to a so-called typewriter-type document processing apparatus that prints in real time using manual input.

You can also specify whether to print underlined characters or not.
Although the determination was made based on the difference in keys, this determination may also be made based on the parameters of a command input manually from a keyboard or the like.

Further, in the embodiment, the output target is determined based on the presence or absence of an underline, but this does not limit the present invention. For example, in the case of a document processing device that can change the font of a specific character, it is also possible to determine whether or not to print a character string whose font has been changed. The point is that it can be determined whether to output or not by using existing modification information for characters.

Further, although a printer is used as an output target device, the present invention is not limited to this. For example, the output target device may be a display device or the like.

[Effects of the Invention] As explained above, according to the present invention, it is possible to specify whether or not to output specific character examples in a document, and the effect that this does not increase the amount of information as document information can be obtained. .
