Abstract

PURPOSE:To print out stored picture information of one original on separate recording paper sheets by applying split processing to picture information into plural sheets of the picture information in the main scanning direction of one original when the size of recording paper is smaller than the size of the original. CONSTITUTION:Suppose that an original 70 received or stored in a memory is of A3 size and the size of recording 71 loaded in the facsimile equipment is of A4 size, then line data up to the A4 size width by one page of the original 70 in the main scanning direction with respect to the width of the original 70 in the main scanning direction are printed out as the 1st print page. Then line data by the A4 size are read from picture information to be printed out in the opposite direction to the main scanning direction and the picture information of an original stored in the memory is printed out on separate print recording paper sheets as the size of the original.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine that is capable of dividing and printing a single document received or stored in a memory.

[Background of the Invention] In a conventional facsimile machine, when the original size of the received original or the memo-winned original by operating the own machine is larger than the recording paper size of the recording paper loaded in the own machine, The image information of the document is reduced to fit the recording paper size and printed out, or only the image information that fits the recording paper size is printed out.

Recently, as shown in FIG. 7, when an A3-sized document 70 is stored in the memory, it is
When recording on the 8th size recording paper 71 (Fig. 8), the image information of the original 70 is divided into A4 size image information A and A, and this is rotated 90 degrees and printed out. Diagram A.

As shown in B, a technique has also been developed in which image information (A) and (B) can be recorded on two recording sheets 71, respectively.

[Problems to be Solved by the Invention] However, with the reduction method, information of the original size cannot be obtained.

A method of printing only the image information that matches the size of the recording paper is not a very good solution because the image information of the document is missing when it is printed.

In the rotation method in which image information is rotated and printed in sections, the image information rotation process is complicated and requires a lot of processing time, so this technology cannot be installed in facsimile machines that aim to be inexpensive.

Therefore, this invention takes these points into consideration,
The purpose of the present invention is to propose a facsimile machine that can print image information of a single document stored in a memory in a relatively small amount of time.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention includes a memory means for storing original image information from an original reading means or a receiving means, and a method for detecting the original size of the memorized image information. a document size detecting means; a printing means for printing this image information; a recording paper size detecting means for detecting the size of the recording paper loaded in the printing means; and a size for determining whether the original size and the recording paper size are large or small. The apparatus is characterized by comprising: a determining means; and an image processing means for dividing image information in the main scanning direction of one document into image information of a plurality of sheets when the recording paper size is smaller than the document size. be.

[Operation] When it becomes clear that the recording paper size is smaller than the original size of the original that has been filled in the memory, find the main scanning width that can be fed at one time, and scan the line data of that main scanning width in the main scanning. Read from the direction side and repeat this for one page.

On the next page, line data corresponding to the main scanning width is read in the opposite direction to the main scanning direction and read out in the same way.
Repeat for pages.

Then, if the recording paper size is A4 size and an A3 size original is stored in the memory as shown in Figure 3A, for example, it will be printed out in two sheets as shown in Figure 3B and C. .

When printing out the next page, the last predetermined section of the previously printed line data is read as the overlap section OR, and white image information is printed in place of the image information on the scanning start side from this overlap section OR. You can also do that. In that case, a printout shape a as shown in FIG. 6 will be obtained.

[Example] Next, an example of a facsimile device according to the present invention will be described in the first example.
This will be explained in detail with reference to the figures below.

For convenience of explanation, functional blocks of the present invention will be explained with reference to FIG.

In the same figure, 12 is a document reading means.

16 is a receiving means.

34 is a memory means in which image information of the original read by the original reading means 12 or original image information received by the receiving means 16 is stored.

40 is an image processing means, which processes the read image information,
Processing is performed such as which area to print or which area to convert to white image information and print.

Reference numeral 18 denotes a document size detecting means for the document stored in the memory.

Reference numeral 20 denotes a detection means for detecting the size of recording paper loaded in the own facsimile machine.

Reference numeral 22 denotes a determining means for determining the size of the document from information on the original size and the recording paper size, and this information is supplied to the image processing means 40.

In the image processing means 40, the main scanning width to be printed out is determined based on this information, and the above-described image processing can be executed.

46 is a printing means, which is not shown, but includes a recording head such as a thermal head, a recording paper cutter means,
It consists of a recording paper loading section, etc.

Among these means, the memory means 34 and the image processing means 4
0. Original size detection means 18. Recording paper size detection means 2
0 and the size determining means 22 can both be configured by software.

In order to achieve the functions shown in FIG. 1, the facsimile machine 10 is provided with image communication processing means as shown in FIG.

In the figure, the image information of the original read by the original reading means 12 is compressed and encoded by the encoding means 32, and then stored in the memory means 34.

The image information read out from the memory means 34 is sent to the decoding means 3.
6, the data is decoded line by line and stored in the line buffer 38.

The image information read by the line buffer 38 is subjected to image processing necessary for the above-described divided printout process by the image processing means 40.

That is, the original size of the original can be determined from the length of one line of the read image information. In addition, the printing means 46
When the recording paper is fully loaded, the size of the recording paper can be determined by a sensor (not shown) provided in this loading section.

After determining the size of the detected recording paper size and document size, and calculating the number of divided prints, the print amount of one line, etc. from the output of the determination, the print unit 46
The printout process is then performed.

Each part in Figure 2 is managed by the CP'U, and the RO
Image processing will be performed based on the control program stored in M (none of which is shown).

FIG. 3 shows an example of divided printout processing.

For convenience of explanation, the original document 70 received or stored in the memory is assumed to be A3 size as shown in A of the same figure, and the size of the recording paper 71 loaded in the machine is A4 as shown in B and C of the same figure.
Size.

In that case, the first page to be printed is document 7 in Figure A.
For a main scanning width of 0, line data from the main scanning direction side up to the A4 size width is printed for one page of the original mark O (FIG. 3B).

The image information to be printed next is read out as line data for A4 size from an example in the opposite direction to the main scanning direction (C in the same figure). Then, the image information of the document stored in the memory is printed out in its original size in parts.

Such divisional printing can be achieved by the process shown in FIG. Among the figures, the original size is A3,
A case where the recording paper size is A4 will be exemplified.

When the control program for divided print processing starts, first the document size of the document 70 stored in the memory is detected, and if it is not A3 size and full size printing is not specified, normal print processing is performed (step 5).
1,52.53).

However, if the document size is A3 size and there is a specification to print out the original size, the memory means 34
The encoded data for one line read from is decoded and sent to the line buffer 38 (step 54).
. Of the line data accumulated in the line buffer 38, only the A4 size is read from the scanning start side (right side) in the main scanning direction and sent to the printing means 46 (step 5).
5).

This process is continued until one page is completed, and when one page has been printed, the recording paper is cut (steps 56 and 57).

Subsequently, the line data of the same page as the first page is decoded and stored in the line buffer 38 (step 58). After that, among the line data that has been accumulated in the line buffer 38, this time the side opposite to the scanning start side (
Only the A4 size is read from the left side) and sent to the printing means 46 (step 59).

The printing process continues until one page is completed, and when printing for one page is finished, the recording paper is cut and the divided printout process ends (step 60.6).
1).

In the above-described example, the starting point of the overlap area for each divided print page may be indicated by an arrow 81 or the like at the leading end of each page, as shown in FIG.

This allows you to easily check the overlapping areas on each page.

Also, as shown in Fig. 6, a part of the overlap area OR is left and the other overlap area is set as a white area.
It is also possible to print separately as shown in C of the same figure.

The above-mentioned example is just an example, and the original size, recording paper size, etc. are not particularly limited, and the number of sheets to be divided and printed out also differs depending on the size difference.

[Effects of the Invention] As described above, according to the present invention, it is possible to perform divisional printout processing at the original size with simple processing, and therefore it is extremely convenient in practical use.
