Abstract

PROBLEM TO BE SOLVED: To provide a facsimile machine adopting a system where an original of the A2 size is divided into four images of the size A4 and the division images are transmitted. SOLUTION: A reader 3 reads an image of an original 2 placed on a contact glass plate 1 and stores the image to a page memory 11 in a facsimile control section 10, a compressor 13 once compresses stored image data and stores the compressed data to an SAF(Storage And Forward) 12 by each page. When the storage of data to the SAF 12 and the storage of data of all pages are finished, the facsimile machine enters a transmission operation to a facsimile machine at the other party. In the transmission operation, each page of the image data is read from the SAF 12 and an expander 14 expands the image into an original image (the image before the compression), and the resulting image is expanded once in a page memory 11. Then a MODEM compressor 15 recompresses the image expanded in the page memory 11 by a compression system suitable for communication and transfers the data to a MODEM 20. The MODEM 20 modulates the transferred image signal and transmits the modulated signal to the machine at the other party that is a receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a facsimile apparatus, and more particularly to a facsimile apparatus having a function of dividing image information into a plurality of blocks and transmitting the divided blocks. Also,
The present invention is not only a facsimile apparatus, but also a scanner apparatus,
Application to copying machines, digital copying machines, etc. is also possible.

2. Description of the Related Art Conventionally, facsimile machines generally tend to be multifunctional. For example, it is provided with a double-page transmission function for dividing one page into four pages, reading and transmitting the page.

As an example of a known technique, the maximum document size that can be handled by a normal copying machine or facsimile machine is A3.
(297 mm × 420 mm). However, as for the copy machine, a copy machine (wide copy machine) capable of copying A2 size (420 mm × 594 mm) is put to practical use for a department handling a large drawing in the construction industry or the like. On the other hand, in the case of facsimile, the standard protocol allows transmission only in the maximum A3 width (304 mm),
In order to transmit an image of an A2 document as it is as an A2 document, a non-standard protocol must be determined, and both the transmitting side and the receiving side must support the non-standard protocol.

Here, in a facsimile (wide facsimile) capable of reading an A2 document, a short side (420 mm side) of the A2 document is set in a main scanning direction and a long side (594 m).
m side) is read in the sub-scanning direction, the A2 document is divided into two at the center in the sub-scanning direction and read as an A3 image of two pages. Scanning and sub-scanning are exchanged and transmitted. In this manner, an A2 original can be transmitted as two pages of an image having an A3 width (297 mm) in the main scanning. Therefore, the image of the A2 document can be transmitted at the same magnification even to a receiver that can handle only up to A3 paper that does not support the non-standard protocol.

[0005]

However, in the above-mentioned conventional technology, there are cases where the receiver can only record up to A4 size.

[0006] Further, since the A2 original has many drawings, it is necessary to avoid image loss near the dividing line when dividing the original.
Read a little overlap near the dividing line. Therefore, when the four images are joined on the receiver side, the four images are slightly overlapped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a facsimile apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
Referring to FIGS. 1 to 4, there is shown an embodiment of the facsimile apparatus of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, FIG. 1 shows a schematic configuration diagram of a facsimile apparatus for transmitting a document on a contact glass. The image of the document 2 placed on the contact glass 1 is read by the reading device 3, and first, the facsimile control unit 10
Is stored in the page memory 11 in the memory. Page memory 11
Are temporarily compressed by the compressor 13 and stored in the SAF 12 for each page. When the reading of one page is completed, the original on the contact glass 1 is replaced and the accumulation in the SAF 12 is repeated in the same manner as described above.

When the accumulation of all pages in the SAF 12 is completed, a transmission operation to the destination machine is started. There, SAF12
The image is read out one page at a time, and is decompressed by the decompressor 14 into the original image (image before compression), and is temporarily expanded in the page memory 11. The image expanded in the page memory 11 is recompressed by the modem compressor 15 into a compression method suitable for communication, and is transferred to the modem 20.
The modem 20 modulates the transferred image signal and transmits the modulated image signal to the other party as a receiver.

Next, as an embodiment of the first aspect of the present invention, an operation will be described in which an A2 image is slightly overlapped with four pages of an A4 image and divided to form an A4 width image and transmitted. FIG. 2 shows the divided image. FIG. 3 shows a flowchart of a processing procedure example of the operation example 1.

First, in the reading of the A2 image in step S1, the main scanning both ends 5mm and the sub-scanning both ends 5mm of the A2 original (420mm × 594mm) are cut 410mm.
A range of 584 mm is read and stored on the page memory (step S2). Here, both ends are shaved.
This is because the non-printed area is not read in advance in consideration of the fact that about 2 mm of the circumference is not printed during printing.

In consideration of the fact that the vicinity of the dividing line is transmitted while being divided at the time of division, the overlapping is made 2 mm here. Therefore, A4 paper (210 mm x 297 mm) on the receiver side
When printing on 4 sheets, if the surrounding area is not printed 2mm,
The output range for A4 paper is 206 mm × 293 mm. The main scanning of the A2 document is equivalent to two sheets in the A4 main scanning direction and is overlapped by 2 mm at the time of division, so that the main scanning of the A2 document is read by 206 mm × 2-2 mm = 410 mm. The sub-scanning of the A2 original is equivalent to two sheets in the A4 sub-scanning direction, and is overlapped by 2 mm at the time of division. Therefore, the sub-scanning of the A2 original is read by 293 mm × 2-2 mm = 584 mm.

The image data stored in the page memory is
As described above, the data is divided into four pages, each of which is compressed as one page, and stored in the SAF 12 (steps S3 to S6).
At the time of transmission, image information is read from the SAF 12 as usual, decompressed and recompressed, and transmitted as four pages of data (step S7).

FIG. 4 shows a flowchart of a processing procedure example of the operation example 2. According to the second aspect of the present invention, one reading is read as half of the A2 document (step S11).
It is stored as two A4 originals (from steps S12 to S1).
4) Further, in the second reading, the remaining 1 /
2 are read (step S15) and stored as two A4 documents (steps S16 to S18), and stored as a total of four sheets. Thereafter, transmission starts sequentially from 1P (step S19). The superposition and the like are the same as in the first aspect of the invention.

According to the third aspect of the invention, the image information transfer start position of the second sheet in the main scanning direction is changed by the value set in the register. For this reason, the range of superposition can be set arbitrarily.

According to a fourth aspect of the present invention, the image information transfer start position of the second image in the sub-scanning direction is changed by the value set in the register. For this reason, the range of superposition can be set arbitrarily. Further, since the second reading start position is set by the value set in the register, the overlapping amount can be set arbitrarily.

According to the fifth or sixth aspect of the present invention, a "division mark" is added to the image stored in the page memory at a position corresponding to an overlapped portion at the time of division. Different marks are added. The A2 size can be easily restored by combining the portions where the marks match. To add such a mark, after storing the image in the page memory, data corresponding to "black" may be written at a specific address of the page memory.

When the A2 original is divided into four parts and transmitted, a mark indicating the division is added to the transmission image so that the original A2 image can be easily restored on the receiver side. . For this restoration, the above-mentioned mark is added to a portion where the overlapping portion of the image coincides, and the four images are easily joined by overlapping the mark on the receiver side.

[0031]

As is apparent from the above description, according to the first aspect of the present invention, an A2 original can be divided into four A4 images and transmitted. It can be transmitted at the same magnification.

According to the second aspect of the present invention, when an A2 original is divided into four A4 images and transmitted, the capacity of the page memory can be reduced by performing the reading twice.

According to the third aspect of the invention, when an A2 original is divided into four A4 images and transmitted, the division position in the main scanning direction can be changed, so that the amount of overlap can be set depending on the situation. Cutting can be prevented.

According to a fourth aspect of the present invention, when an A2 original is divided into four A4 images and transmitted, the dividing position in the sub-scanning direction is made variable so as to leave a space corresponding to a two-page spread original. In this case, it is possible to select whether to perform the superposition in accordance with the above.

According to a fifth aspect of the present invention, when an A2 original is divided into four A4 images and transmitted, the division mark indicating the division position is set at the same position on the overlapping area of the four divided images. By adding, the images received as A4 on the receiver side can be easily connected when the images are connected and restored to the A2 image.

According to the sixth aspect of the present invention, when an A2 original is divided into four A4 images and transmitted, different division marks are added. Therefore, when the A2 original is restored to an A2 image by joining, it is easily connected. Can be matched.
