Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The inventions of the present application relate to a facsimile machine, and particularly to a facsimile machine that selects functions based on marks placed on a received document.

(Prior Art) Recently, with the spread of facsimile machines, facsimile machines have appeared that temporarily store image information of a received document in a memory and record and output each page on a plurality of sheets.

Conventionally, such facsimile apparatuses include those that employ a stacking method and those that employ a sorting method as a recording/output method. In other words, in the stacking method, when recording and outputting multiple pages of a received document one by one, multiple sheets of the same page are stacked, and the same page is stacked and recorded for each page in sequence. It is something. On the other hand, in the sorting method, when recording and outputting a plurality of pages of a received document one by one, the sheets are stacked one by one in page order, and the stacked pages are further stacked in multiple sets to be recorded and output.

In conventional facsimile machines, only one of these recording methods is fixedly adopted.

In addition, to maintain the confidentiality of communications, facsimile machines
A function that allows you to switch recording paper between normal reception records and confidential reception records, and a function that allows you to select whether received image information is stored in memory or recorded and output depending on whether confidentiality is required. In addition, it is equipped with various functions such as a polling function, and when selecting these functions on the sending side, conventional facsimile machines use facsimile control signals or OMR (Opt
cal Mark Reader) and OCR (Opt
This is done by reading the function identification mark attached to the document using the ical Character Reader.

(Problem to be Solved by the Invention) However, in such conventional facsimile machines, the stacking method and sorting method are fixed as recording output methods, so it is difficult to select the recording output method on the sending side. There is a problem in that it is difficult to sort the recording paper, and even if the receiving side has a function that allows selection on the sending side, selection must be made using facsimile control signals. , expensive OM on the receiving side
There is a problem in that the facsimile machine is expensive because it requires R, etc.

(Object of the Invention) Therefore, the invention according to claim 1 includes a stack method and a saw method as recording output methods, and determines the recording output method by detecting a predetermined mark made on the first page of a received document. By doing so, the purpose is to enable the sending side to select the recording/output method, select the recording/output method suitable for the transmitted document, and to simplify and facilitate the sorting of the recorded documents.

Further, in the invention as claimed in claim 2, a mark for function selection is applied to the leading part of the first page of the transmission document in the sub-scanning direction so that the same image pattern does not continue, and the mark is used to check the continuity of the image pattern. By detecting this, function selection can be performed without using facsimile control signals or without using expensive OMR or OCR, thereby creating an inexpensive facsimile machine that can perform function selection from the sender side. The purpose is to

(Structure of the Invention) In order to achieve the above object, the invention according to claim 1 temporarily stores the image information of the received multiple pages of original in a memory, and when each page is recorded and outputted on multiple sheets, each page is This facsimile machine is capable of selecting a stacking method that records and outputs multiple sheets at once for each document, and a sorting method that records and outputs multiple sheets by arranging them in page order and dividing them into multiple sets. The invention according to claim 2 is characterized in that the facsimile machine selects various functions by detecting a predetermined mark made on a received document. The predetermined mark is applied to the first page of the original in the sub-scanning direction, and the predetermined mark is applied to an image in which lines of the same image pattern are not consecutive beyond the predetermined line, and the mark is applied to each line. This is characterized in that detection is performed by comparing the image patterns of and checking the continuity of the same image pattern.

Hereinafter, a detailed description will be given based on examples.

1 to 4 are diagrams showing an embodiment of the invention according to claims 1 and 2. FIG.

FIG. 1 is a block diagram of a facsimile machine l, which includes a system control section 2, a ROM (Rea)
d 0nly Memory) 3, 'Line control section 4
, a mark identification section 5, an image memory 6, a compression/reproduction section 7, a line buffer 8, a plotter 9, a scanner 10, an operation section 11, and the like.

The ROM 3 stores basic programs for the facsimile device 1 and programs for mark identification processing and recording output processing of the present invention, and the system control unit 2 controls each part of the facsimile device 1 according to the programs in the ROMa. At the same time, the mark identification process and the recording output process of the present invention are executed.

A line is connected to the line control unit 4, and the ROM 3 controls communication with other facsimile machines connected via the line.

The mark identification unit 5 includes two counters 21 and 22 and a line buffer 23 and 24 for two lines, and identifies marks, which will be described later, from image data input via the line control unit 4.

That is, the counter 21 is initially set to a predetermined count value corresponding to the number of lines of the mark (for example, when the line density is 7.7).
In the case of Hon/Tsuru, a count value of 100 lines (100) is counted, and the number of lines that are not the same image pattern among the line data input from the line control section 4 is counted down. The counter 22 is initially set to a count value for a predetermined number of lines at the top of the page (for example, a count value for 400 lines when the line density is 7.7 lines/1 line: 400). It is counted by counting down from to a predetermined line. The leading portion counted by the counter 22 is normally a portion where nothing is written in the document, and is a portion where image data of the same image pattern continues. That is, as shown in FIG. 2, a mark 32 is placed at the beginning of the first page of a document 31, and if the mark 32 is not placed, this beginning portion is usually a portion where the same image pattern continues.

This mark 32 is a square with diagonal lines inside.
The image pattern is different for each line. The line buffers 23 and 24 each store one line of image data (line data), the line buffer 24 stores current line data to be recognized (current line data), and the line buffer 23 stores the current line data (current line data). Line data of the previous line (previous line data) to be compared with the line data is accumulated. The system control unit 2 determines whether the previous line data in the line buffer 23 and the current line data in the line buffer 24 are line data of the same image pattern, and controls the setting/resetting of the counter 22 based on the determination result. .

The identification process of the mark 32 in the mark identification section 5 will be explained later in the section of operation.

The image memory 6 has a capacity to store image data for a plurality of pages, and stores received image data and image data for transmission.

The compression/reproduction unit 7 encodes (compresses) the image data using a predetermined encoding method, such as the MH method (Modified Huffman method), the MR method (Modified READ method), or the M2R method. decode the image data.

The line buffer 8 has a capacity to store 1947 minutes of image data, temporarily stores the image data decoded by the compression/reproduction unit 7 and recorded by the plotter 9, and also temporarily stores the image data read by the scanner 10. temporarily stored.

As the plotter 9, for example, a thermal recording device using a thermal element is used, and the block 9 records on ordinary recording paper directly or indirectly via an ink sheet.

As the scanner 10, for example, a CCD (Charg
A line scanner using an eCoupled Device is used to read a document line by line and output it as image data.

The operation unit 11 includes a keyboard, a display unit, etc., and inputs various commands and displays various information.

Next, the action will be explained.

The present embodiment is characterized in that the facsimile device 1 has a stacking method and a sorting method as recording output methods, and the selection of the function is performed by detecting a mark 32 attached to a document 31. . The mark identification process and recording output process will be explained below.

When the facsimile machine 1 receives an incoming call request from the line, the line control unit 4 automatically receives the call, executes the facsimile communication procedure, and enters reception processing. When image data is transmitted from the other party's facsimile device via the line, the facsimile device fil transfers the received image data to the line buffer 24 of the mark identification section 5, and when one line is accumulated, the system control section 2 compares the current line data in the line buffer 24 with the previous line data in the line buffer 23 to perform mark 32 recognition processing. The line data for which mark recognition processing has been completed is stored in the image memory 6.

That is, as shown in the flowchart in Figure 3,
When one line of image data is input from the line control wholesaler 4 to the line buffer 24 (step S), the counter 2
2 decrements the count value by 1 and counts down the number of lines from the first line. The system control unit 2 first checks whether the count value of the counter 22 has reached the initial setting value (400 lines in this embodiment), that is, whether 400 lines of data have passed from the first line. step SZ),
If it has not passed, the current line data in the line buffer 24 and the previous line data in the line buffer 23 are compared to check whether they are the same image pattern (step S
3). This image pattern comparison is performed by the system control unit 2, but the comparison method differs depending on the image data encoding method. In other words, in the case of the MR method, since encoding is performed in one dimension, the previous line data and the current line data are subtracted, and if the subtraction result is "0", it is the same image pattern and must be "0". It can be seen that the image patterns are different. On the other hand, in the MR method and the M2R method, encoding is not performed within a one-dimensional range, so it cannot be determined whether the image patterns are the same by simple subtraction. However, in the MR method and the M2R method, The image pattern is a continuation of the same line pattern as the previous line (sometimes, the line pattern shown in Figure 4 (a)
), as shown in Figure 4(C), when the reference line data and coding line data when encoding is performed have the same image pattern, the code pattern is as shown in Figure 4(a). , EOL code + “0” + “11 In Fig. 4(b), EOL code + “0” + “111
” In Figure 4 (C), EOL code + “0” + “1111
1', - EOL code for boat fishing + "0" 10 "1 consecutive"
This is the pattern. Here, the EOL code is ooo
ooooooooooi". Therefore, when the image data encoding method is the MR method or the M"R method, the first 13 bits of the line data in the line buffer 24 have a pattern of EOL+"0". What to check and if this pattern applies,
The remaining data in the line buffer 24 is sequentially set to “1”.
” bits, and if all data is “1”, it can be determined that the image pattern is the same as the previous line. Then, the pattern data of EOL + “0” is stored in ROMa. The system control unit 2 compares the data in the line buffer 24 with the EOL+“0” tab turn in the ROMa to determine the EO.
It is possible to check whether L+“0”.

As a result of comparing the current line data with the previous line data, if the image pattern is the same as the previous line data, mark 3 is selected.
2, the counter 21 is reset and the next line is waited for (steps Sz, S+).

If the current line data is not the same image pattern as the previous line data, it is determined that it is the mark 32, and a check is made to see if the counter 21 is counting (step S).
, if counting is not in progress, the counter 21 is set to an initial value and the process returns to step S (step S6). When the counter 21 is counting, the count of the counter 21 is directly n.
is decremented by 1 (step S7), and it is checked whether the count value of the counter 21 is "0" (step Sa).

When the count value of the counter 21 is not "0", it is determined that the size of the mark 32 has not been reached, and step S
Return to step 1 and continue checking the next line data (steps S, -S, ). The count value of counter 21 is 01
If so, it is determined that the mark is 32, and it is determined that the stack method has been selected as the recording output method (step S). That is, when the mark 32 is placed in the ROMa, data indicating that the stacking method is adopted as the recording method is stored in the ROMa, and data for the stacking method and the sorting method are stored in the ROMa in advance. Contains the recording output program. Therefore, when the mark 32 is applied to the document 31 and the mark 32 is recognized by the mark recognition unit 5 in the mark recognition process, the system control unit 2 determines that the stacking method has been selected and stores the image in the image memory 6. The stored image data is outputted starting from the first page, and the image data of the same page is output one by one for each recorded number of sheets.

That is, the system control unit 2 first successively reads the image data of the first page in the image memory 6 as many times as the number of images to be recorded, causes the plotter 9 to record it, and when the recording of the number of images of the first page is completed, the image data of the next page is read. The image data of the page is similarly read out as many times as the number of sheets to be recorded and recorded in block 9. By continuing this process until the final page, stacked recording is performed.

On the other hand, when the counter 22 counts 400 lines without recognizing the mark 32 (step S2), it is determined that the mark 32 has not been applied and the sorting method has been selected, and the image memory 6 The image data stored in the image data is sequentially output one page at a time from the first page to the last page, and the output processing of this image data is performed for the number of records to be recorded.

That is, the system control unit 2 first reads the image data of the first page in the image memory 6 and causes the plotter 9 to record it, and then reads the image data of the next page and causes the block 9 to record it. When this process is carried out up to the last page, the same process is repeated for the number of sheets to be recorded, and recording is performed in a sorting manner.

In this way, it is possible to apply the mark 32 as discontinuous images of the same image pattern at the beginning of the document 31 where the same image pattern usually continues, and to recognize this mark 32 by simple subtraction processing or simple pattern comparison processing. The mark 32 can be recognized without using conventional expensive OMR or OCR. Therefore, the facsimile device 1 that allows function selection from the sending side can be made inexpensive, and the facsimile device 1 can be made inexpensive.
The usability and convenience of the system can be improved.

Further, it is possible to select a stacking method or a sorting method as a recording/outputting method, and it is possible to select a recording/outputting method suitable for the document. Therefore, sorting the recorded documents on the receiving side becomes simple and easy.

In the above embodiment, the recording output method is switched between the stack method and the sort method by changing the method of reading image data from the image memory 6, but the present invention is not limited to this. For example, image data is read from the image memory 6 starting from the first page and outputted one by one, and this reading is continued until the last page. On the other hand, the plotter 9 may be provided with a plurality of recording paper trays, and the order in which recording paper is ejected to the recording paper trays may be switched depending on the recording output method. In this case, in the sorting method, blocks 9 continuously record the number of sheets starting from the first page, and the recording sheets of each first page are sequentially discharged to separate recording paper trays. By sequentially performing this process for each page, it is possible to record and output in a sorted manner.

(Effect) As described above, in the invention according to claim 1, it is possible to select the recording output method of the sorting method and the stacking method based on the mark made on the document, so it is possible to select the recording method appropriate for the document. This makes sorting the recorded manuscripts simple and easy.

Further, in the invention as claimed in claim 2, since the function can be selected by recognizing the mark made on the transmitted document without using expensive OMR, OCR, etc., the function can be selected from the transmitting side. The facsimile device can be made inexpensive, and the usability and convenience of the facsimile device can be improved.
