Abstract

PURPOSE:To prevent missing of a ruled line by using a data of a ruled line font memory so as to bury the character interval and line interval when a specific code of a ruled line is converted into a raster data in a picture processing unit usable for a copying machine for lots of kinds of media. CONSTITUTION:An MPU 221 reads a test code via a bus, loads a raster data corresponding to a text code from a character generator 230 or a ruled line font ROM 501 and writes it in a page memory 228. Taking ¦ and - of the ruled line font, fonts A', B' are subject to raster expansion horizontally and vertically. Since the font is stored in a ruled line font ROM 501, the address is moved respectively with respect to the ruled line font of ¦ and -, the font image is loaded from the ROM 501 and expanded into the page memory 228. Thus, it is possible to bury the missing of the ruled line due to character and line interval caused in the expansion of the ruled line font.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an image processing device, and more particularly, the present invention relates to an image processing device, and more particularly, it is applicable to a multi-media copying machine that is capable of copying between different media in addition to copying from a paper original onto paper. The present invention relates to an image processing apparatus.

[Prior art]

In a multi-media copying machine, the document file on the floppy disk contains information on the character pitch LP and line pitch CP (text printing format) as shown in FIG. The code data is expanded into the image memory by character transfer.

Ruled line data is usually stored as vector data in a separate file from text code data, or in a separate area even within the same file, but there is no standard for the format of this vector data, and each company has different formats. It is expanded into image memory using a dedicated algorithm suitable for that format. Such a document file is inappropriate considering the functions of a multi-media copying machine.

On the other hand, some of the ruled line data is based on the JIS standard as shown in Figure 14.
Some fonts express ruled lines using codes (hereinafter referred to as "ruled line fonts"), and therefore, in this case, code data for characters and ruled lines coexist in a document file of text code data. Furthermore, since the code data of this text file is standardized by JIS, it is possible to develop ruled lines in an image memory using a single algorithm.

However, as described above, the image memory development of code data is performed while maintaining the pitch between characters and the pitch between lines, so although the character code is good, when developing ruled line fonts, omissions occur as shown in Figure 15. .

〔the purpose〕

The present invention has been made to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to provide an image processing device that can be used in a multi-media copying machine and can prevent missing ruled lines. .

It is equipped with a character generator memory that stores bit images corresponding to codes and ruled line codes, and a ruled line font memory that stores ruled line bit images for character spacing and line spacing determined by the print format. The present invention is characterized in that when converting a specific code into raster data, data in the ruled line font memory is used to fill in character spacing and line spacing.

It also controls via 110329 in order to notify the floppy disk memory device of start and stop commands from the operation display unit 4 and abnormal conditions such as paper jams in the printer 3.

Next, the operation display section 4 will be explained with reference to the schematic plan view of FIG.

The operation display section 4 includes a 4iI quasi-operation section 460, a dot liquid crystal display LCD 465, and a special operation section 461 having soft keys 466 as a copying machine. The standard operation section 460 is for use when using the 1. paper-to-paper copying function, including a numeric keypad 462 for setting the number of copies, a number display section 463, a print start key 464, and a keypad for setting copy conditions.
It is composed of a display section 470 and the like. Special operation section 461
is FD note 1. This is used in the copy mode for copy/reproduction, and is composed of soft keys (for data manual input) 466 and a liquid crystal display 465.

These are connected to the microcomputer system through the 110 port 232 in the floppy disk memory (see Figure 6).The meaning of the soft keys 466 and the display data on the liquid crystal display 465 are all stored in this microcomputer system. Determined by the program.

The feature that characterizes the present invention is that in addition to the conventional digital copier standby function of ``a paper-to-paper copying function that outputs the image signal read from the scanner to the printer,'' it also has the function of ``outputting the image signal read from the scanner to the floppy disk.'' (hereinafter referred to as FD) is a paper-to-FD copy function that records image signals (raster data, raster data, etc.) recorded on rFD.
These three functions include a copy function from an FD to a computer that handles three types of data (vector data, text data) and outputs them to a printer.

Of the above three functions, copying from paper to FD and FD
Copying from to paper will be described below.

In copying from paper to an FD (flow chart in FIG. 11), first set the original to be recorded on the FD into the scanner l, and operate the operation display section 4 to set copy conditions.The copy conditions here are as follows: For example, selection of copy mode from paper to FD, setting of copy range, selection of FD type, input of file name or file name for file identification in FD, etc. Thereafter, the print start key 464 in FIG. 10 is pressed to complete the operation.

To explain the flow and effect of a series of operations at this time, the copy conditions are set on a floppy disk memory device (hereinafter referred to as
The program stored in the ROM 223 in the FDM (FDM) is interactively executed via the I10 boat 232 using the liquid crystal display 465 and soft keys 466 of the special operation unit 461 in the operation display unit 4. In this case, the display method and operation are as follows: Since the method is not related to the gist of the present invention, a detailed explanation will be omitted.

When the setting of the copy conditions is completed and the operator presses the print start key 464, the program starts on the FDr/F220.
Check the FD through.

The FD check mentioned here includes, for example, whether the FD is set in the FDD, whether it is formatted, and whether the file name or file name is registered twice.

When the FD check is completed, the program executes the scanner reading operation through the scanner I/F 224. The data read from the scanner I is passed through a serial-to-parallel data converter 226 to the page memory 22.
Expanded to 8. Since the page memory capacity is reserved for the original paper, development in the memory continues until the original reading operation is completed.

When the reading operation is completed, the contents of the page memory are then recorded on the FD. This recording operation is performed through the FDDI/F 220.

Next, copying from FD to paper (flow chart in FIG. 12) will be explained.

The user sets the FD on which the file to be copied is recorded into an FDD that matches its size, and operates the operation display section 4 to set copy conditions. The copying condition settings here include selecting the copying mode from FD to paper, setting the number of copies, and the size of the FDD to be copied (8', 5.25").

3.5”) i!Sawa et al.

This copying condition setting is performed interactively by a program stored in the ROM 223 in the FDM through the I10 port 228 and on the liquid crystal display 465 of the special operation section 461 in the operation display section 4 and on the soft keys 466.

RO when the operator finishes setting the copy conditions.
The program stored in M223 checks the FD through FD1/F220.
Is the FDD set in the FDD and ready? ■ Is there any problem with the FDD hardware? ■ Is the file
The format is 0, etc., if it can be processed by the program in the ROM 223. If a failure occurs during these checks, the error occurrence is notified to the 'ζ operator through the operation display section 4, and an error handling routine is entered.

Since this error processing is not the gist of the present invention, its explanation will be omitted.

Next, the program reads the file directory to be copied, displays a file list on the special display section 461 of the operation display section 4, prompts the operator to select the file to be copied, and presses the soft key 466 on the operation display section 4 as well. to request input of selection information. At this point, the series of condition settings are completed, and the operator presses the print start key 464.

When the print start key 464 is pressed, the program executes the FD reading operation, and if the read data is raster data (data from a scanner or facsimile), it is expanded to the vegetable memory as is, and if the data is text code data ( (data from computers, word processors, etc.) are stored in working memory.

The text data stored in the working memory is converted into a rask pattern according to the code using the character generator 230, and then developed in the page memory 228.

When the expansion into the page memory 228 is completed, the contents of the page memory 228 are output to the printer 3. In this case, if the file contains 0th page data that uses the format stored in the FD, the print format is repeated from the execution of the FD reading operation, and if the number of copies is 2 or more, , the contents of the page memory are repeatedly output for that number of pages.

Copying ends when all data has been output to the printer 3.

Referring again to FIG. 7, working memory 222 stores the text code of the document.

The MPU 221 reads the text code via the bus and sends raster data corresponding to the text code to the character generator 230 or the ruled line font ROM 501.
Load from and write to page memo I7228. The data writing positions of the page memory 228 are, as shown in FIG. 16, right margin (RM), left margin (LM), top margin (UM), bottom margin (BM), character pitch (LP),
Data such as line pitch (CP) is written in the print format in the document file, and the relationship between that data and the actual address of the page memory 228 is
Since it is stored in MPU 221, based on it
is calculated. In FIG. 16, P8 is the printable area P
The lateral length of R, P.

is the vertical length of the printable area, C1l is the horizontal length of the character data, C9 is its vertical length, and DPR is the document print area.

Right, left, top and bottom margins RM, LM for printable area
, UM and BM is the document printing area,
One character on the first line is written at position A in FIG. The writing position of the next character is the position B in the figure, and if there is a code (CR), it is written at the position C, which is the first character on the next line.

For example, the character data in the character generator 230 is C, XC, and dot data, and the printer 3
When the writing density of is D lines/Tsuru, the coordinate values (address values) of A, B, and C are respectively A ” P g X D X (UMX D + Cy
-1)+ LMX DB curse A+Cx +LPXD C-A+PX XDX (CV -1)
+ (PXD).

That is, the address of the nth line, mth character is (address) a
s''A+m (B-A)+n (C-A).

Now, normal characters (alphanumeric characters, kanji, etc.) may be converted into raster data in the page memory 228 by calculating the above address, but in the case of ruled fonts, omissions may occur as described above (the Figure 15).

Therefore, we focused on the - and 1 of the ruled line font, and changed the fonts A' and B' as shown in Figure 17 to the left and right (A' for the ruled line font in Figure A), and the upper and lower sides (the ruled line font in Figure B), respectively. Raster expansion is performed on B').

This font is stored in the ruled line font ROM 501, and for the ruled line fonts of - and 1, character pitch (LP) XCx dots and line pitch (C
P) Prepare several types of XC and dot sizes. The reason why there are several types is because the pitch between characters and the pitch between lines do not have to be continuous values.

While the MPU 221 is expanding the text code in the working RAM 222 to the page memory 228, -
(i.e., A in Fig. 17) or 1 (i.e., B in Fig. 17) after developing the ruled line font, in the case of -, the left font address (address'), - (LP) ×
(-) Move the address to the right font address - (address > nm + cX, load the font image from the ruled line font ROM 501, and expand it to the page memory 228.

The address is moved to DXPExD, a font image is loaded from the ruled line font ROM 501, and the font image is expanded to the page memory 228. If the operation up to this point is shown in a flowchart, the 18th
It will look like the figure.

As is clear from FIG. 19, which shows how the ruled lines are developed in the page memory 228 using this method, this method eliminates the problem of missing ruled lines.

Also, if - or l are consecutive, the same ruled line font (A' or B' in Figure 17) is used twice between the fonts.
The output image is not affected even though it is expanded once.
If the font immediately before or on the line is - or l, the font may not be expanded to the right or above.

In Figure 19, A is - font, B is 1 font, A
', B' indicate the fonts - and 1 stored in the ruled line font ROM 501.
