Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device, and particularly to a facsimile device that can read large-sized documents such as A1 size (see Japanese Industrial Standards).

[Conventional technology]

Conventionally, if the recording width (reception size) of the recording section or recording paper on the receiving side facsimile device is smaller than the size of the document read by the reading section of the sending side facsimile device (original size), the receiving side facsimile The device automatically reduced the size of the image and recorded it on recording paper as an image copy.

Therefore, if you want the original size (original size) to be recorded as an image copy on the receiving facsimile device, the original must be divided into multiple sheets using scissors or the like in advance to match the reception size of the receiving facsimile device. A facsimile machine on the sending side reads the divided documents into multiple sheets and sends them to a facsimile machine on the receiving side. A plurality of image copies output from the facsimile machine on the receiving side are pasted together with glue or the like as needed to obtain an image copy of the same size as the original document before division.

Conventionally, in order to reduce the effort and time involved in dividing a document and pasting together image copies, scanned image data is automatically divided into multiple pages and sent. The area where images overlap with each other (hereinafter referred to as the image overlap area) is recorded in the adjacent area of the image copy, and dashed lines indicating the boundaries of the image overlap area and marks indicating the correspondence between the image overlap areas are also recorded. Various facsimile devices have been proposed (Japanese Patent Application Laid-Open No. 60-93871, Japanese Patent Application Laid-open No. 198873-1989,
(See Japanese Patent Application Laid-Open No. 61-295760, etc.).

[Problem to be solved by the invention]

However, with the above-mentioned conventional facsimile device, the read image data was only divided into either the main scanning direction or the sub-scanning direction, so when sending a large original to a facsimile device with a small reception size, etc. Another problem is that it is not easy to determine how to combine a plurality of image copies in the main scanning direction and the sub-scanning direction to obtain an image copy of the same size as the original.

Additionally, if marks are recorded to indicate the correspondence between overlapping parts of images in order to make it easier to judge the combination of image copies, the marks will remain on the image copies restored to the same size as the original. So,
There was a problem that the image was distorted.

In view of the above-mentioned points, an object of the present invention is to divide the image data of a large-sized document read into a plurality of pages in the main scanning direction and the sub-scanning direction according to the reception size of the receiving facsimile device, and format the image data. To provide a facsimile device which transmits data for each divided page and also transmits reduced image data with lines indicating page boundaries, thereby facilitating the restoration of an image copy of the same size as an original. It is in.

[Means to solve the problem]

The facsimile device of the present invention includes a reading section having a reading width capable of reading large-sized originals, and a data memory having a large memory capacity capable of storing image data read all at once from the large-sized original by this reading section. The image data stored in this data memory is divided and formatted into a plurality of pages in the main scanning direction and the sub-scanning direction according to the reception size of the facsimile device on the receiving side, and the image data is transmitted page by page. The present invention is characterized by comprising a main control section that reduces the image data according to the received size, adds lines indicating page boundaries, and transmits the reduced image data.

[Effect]

In the facsimile device of the present invention, the reading unit has a reading width that allows reading large-sized originals, and the data memory has a large memory capacity that can store image data read in batches from large-sized originals by the reading unit. Then, the main control unit divides and formats the image data stored in the data memory into multiple pages in the main scanning direction and sub-scanning direction according to the reception size of the receiving facsimile device, and transmits the image data page by page. At the same time, the image data is reduced according to the received size, lines indicating page boundaries are added, and the image data is transmitted as reduced image data.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing a facsimile apparatus according to an embodiment of the present invention. The facsimile apparatus of this embodiment includes a main control section 1 including a central processing unit (CPU), an operating section 2 in which various operating members are provided, a reading section 3 including a line image reading sensor, and a line print head. a recording section 4 consisting of a storage unit 4, etc., and a data memory 5 for storing image data.
The data memory 5 stores the reduced image data (hereinafter referred to as reduced image data).
A random access memory (RAM) 6 is used to set page addresses, a read-on memory (ROM) 7 is used to store programs that control the main control unit 1, broken lines indicating page boundaries, etc., and a read-on memory (ROM) 7 is used to modulate and demodulate transmitted and received data. Its main parts are composed of a modem 8 that performs the transmission, and a network control unit (NCU) 9 that selects the connection partner of the transmission path.

The reading section 3 has a reading width that can read an A1 size document, and when it is composed of line image reading sensors, it may be composed of one line image reading sensor, and is arranged in a staggered manner. The sensor may be composed of a plurality of line image reading sensors.

The data memory 5 is composed of a random access memory and the like, and has a large memory capacity that can store image data of an A1 size document all at once.

Referring to FIG. 2, the processing in the main control unit 1 when transmitting a document in original size mode is divided into a step 11 of transferring the document to the data memory, a step 12 of connecting the transmission line, a step 13 of obtaining the received size. Step 14 for determining necessity, data memory formatting step 15, image data reduction transfer step 16,
Broken line addition step 17, reduced image data conversion step 18, converted data transmission step 19, reduced image data end determination step 20, page address setting step 21, and page data conversion step 22
, conversion data transmission step 23, page end determination step 24, and all page end determination step 25
, transmission path release step 26, and normal data conversion/
It consists of a transmission processing step 27.

Next, the operation of the facsimile apparatus of this embodiment configured as described above will be explained. Note that transmission of a document in original size mode will be described here.

When a document is set in the reading section 3 of the facsimile machine on the sending side, and the operation section 2 is instructed to send the document in the original size mode, the main control section 1 controls the reading section 3.
The original is read one by one and the image data is transferred to the data memory 5 and stored all at once (step 11).

Next, the main control unit 1 makes a call to a facsimile device (not shown) on the receiving side via the modem 8 and network control device 9, and when a response to the incoming call is returned, connects the transmission line. (Step 12), acquires the recording width (reception size) of the recording unit or recording paper in the receiving facsimile device (Step 13),
The acquired reception size is compared with the size of the read image data (original size) to determine whether it is necessary to transmit the image data in parts (step 14).

If it is necessary to divide the image data, that is, if the received size is smaller than the document size, the main control unit 1 divides the image data on the data memory 5 in the main scanning direction and/or sub-scanning direction according to the received size. Divide and format into multiple pages (Step 15). Hereinafter, the image data of each divided page will be referred to as page data.

Next, the main control unit 1 reduces the image data on the data memory 5 according to the received size and transfers it to the random access memory 6 (step 16), and reduces the image data on the data memory 5 according to the received size and transfers it to the random access memory 6 (step 16). A broken line indicating the boundary of the current page is added to the reduced image data transferred to the random access memory 6 (step 17).

Next, the main control unit 1 converts the reduced image data marked with a broken line on the random access memory 6 into transmission data (step 18), and receives the converted transmission data via the connected transmission path. Send to the local facsimile device (Step 19). The main control unit 1 then controls the random access memory 6
It is determined whether the above reduced image data is finished (step 20), and if it is not finished, the process returns to step 18 and repeats the process.

Random access memory 6 determined in step 20
When the above reduced image data is completed, the main control unit 1
sets the address of the first page data of the image data on the data memory 5 (hereinafter referred to as page address) in the random access memory 6 (step 21), and sets the page data of the corresponding page of the image data as the transmission data. Convert (step 22),
The converted transmission data is transmitted to the receiving facsimile device via the connected transmission line (step 23).

Then, the main control unit 1 determines whether or not the transmission of page data for one page is completed (step 1).
24) If the transmission of page data for one page has not been completed, the process returns to step 22 and repeats the process.

When the transmission of page data for one page is completed, the main control unit 1 determines whether transmission of page data for all pages in the image data on the data memory 5 has been completed (step 25), and If the transmission of page data has not finished,
Returning to step 21, the page address of the next page of the image data on the data memory 5 is set in the random access memory 6, and the process is repeated.

When the transmission of page data for all pages of the image data on the data memory 5 is completed as determined in step 25, the main control section 1 releases the transmission path (step 26) and ends the process.

Furthermore, if it is determined in step 14 that there is no need to divide and transmit the image data, that is, if the received size is equal to or larger than the document size, the main control section 1 performs normal image data conversion processing and transmission processing, and then transmits the image data. (Step 27) and release the transmission line (Step 27).
26), end the process.

For example, if an A1 size document as shown in the left diagram of Figure 3 is sent in original size mode to a facsimile machine that has a receiving size of A4 size,
As shown in the center diagram of Figure 3, the image data of a sized original is formatted by being divided into 8 A4-sized pages, and before the page data of each divided page is sent, it is reduced to A4-sized. A broken line indicating a page boundary is added to the reduced image data, and the data is transmitted. As a result, the facsimile machine on the receiving side has 8
Prior to outputting an A4-sized image copy, a reduced image copy with dashed lines indicating page boundaries is output. Therefore, if you want to obtain an image copy of the same size as an A1 size original, you can easily make an image copy of the same size as the original by referring to the reduced image copy and combining 8 image copies. can be obtained.

In addition, in Fig. 3, we have explained the case where the page data is not given the image overlap area or the line indicating the boundary of the image overlap part, but for example, as shown in Fig. 4, the image data of an A1 size document is When formatting, each page may be divided into nine A4 size pages by providing an image overlap area, and a broken line may be added to indicate the boundary of the image overlap area. In this way, the nine image copies are given dashed lines that indicate the boundaries of the image overlap area, and the reduced image copies are given dashed lines that indicate the page boundaries and dashed lines that indicate the boundaries of the image overlap area, so that the original It becomes easier to restore an image copy of the same size.

By the way, in the above embodiment, a case was explained in which broken lines were used as the lines indicating the boundaries of pages and the lines indicating the boundaries of image overlap areas, but these lines can be replaced by other lines such as thin lines, dashed dotted lines, and dashed double dotted lines. Of course, it is also possible.

Furthermore, although the case has been described in which the reduced image data is transmitted before the page data, it goes without saying that the reduced image data may be transmitted during or after the transmission of the page data.

Furthermore, although we have shown an example in which the original size on the sending side facsimile device is A1 size and the received size on the receiving side facsimile device is A4 size, if the original size is other sizes such as A0 size or B1 size, It goes without saying that the received size may also be other sizes such as B4 size, B5 size, A5 size, etc.

〔Effect of the invention〕

As described above, according to the present invention, the image data of the scanned original is divided into a plurality of pages in the main scanning direction and the sub-scanning direction according to the reception size of the facsimile device on the receiving side, and the data of each page is formatted. By transmitting reduced image data with lines indicating page boundaries added, it is possible to copy multiple images even when sending a large original in original size mode to a facsimile machine with a small receiving size. By combining these methods, it is possible to more easily determine whether an image copy of the same size as the original can be obtained.
