Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a facsimile device that records image information on cut paper.

[Prior Art] Conventionally, facsimile machines that record image information on cut sheets include those that can use one type of cut sheet and those that can use multiple types of cut sheets. Also, for items that can use multiple types of cut paper, such as B4/A4 size switching,
There are cases where the recording widths are different and cases where the recording widths are the same, such as when switching between letter and zigal sizes.

First, when there is only one type of cut paper, when image information exceeding the cut paper length is received, the excess image information is recorded on the next cut paper.

In addition, if there is little information that exceeds the amount, controls such as truncating this information are performed.

In addition, if multiple types of cut paper with different recording widths can be used, from the transmitter side, the A4 size or B4 size
After determining to transmit the size, the same operation as in the case of having a series of one type of cut paper is performed.

On the other hand, if multiple types of cut paper with the same recording width but different lengths can be used, only one recording paper can be set.
type, and the facsimile machine recognizes whether the size is set to letter or legal.
Based on the set size, the same operation as in the case of having one type of cut paper described above is performed.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, even when the excess image information is too large to be cut off but too small to be recorded on the next cut paper, it is necessary to cut two sheets. The disadvantage was that it had to be recorded on paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can effectively cope with the reception of image information that exceeds a standard size of recording paper.

[Means for Solving the Problems] The present invention is a facsimile device that records received image information on a cut sheet of standard size, in which the excess of the received image information in the sub-scanning direction with respect to the standard cut sheet is within a first predetermined value. In some cases, the excess amount is not recorded, and when the excess amount is less than the first predetermined value -L, the received image information is reduced and recorded.

The present invention also provides a facsimile device that records received image information on a plurality of (1-n) cut sheets of standard size, comprising:
If the excess amount is equal to or greater than the second predetermined value for the m-th (l≦m≦n) standard-sized cut paper among each standard-sized cut paper, the cut is made in a size larger than the m-th standard cut paper. When paper is available, image information is recorded on this large size cut paper, and when there is no cut paper larger than the -1-mth standard cut paper, this m (= n
) is characterized in that image information is recorded on two sheets of standard cut paper of number H.

[Function] In unreleased ■ and η, when image information that exceeds the standard size recording paper is received, the image information is reduced and recorded and divided into two sheets of paper. It is possible to reduce the number of opportunities for recording, and to make effective use of recording paper.

In addition, when setting multiple types of standard sizes at the same time, if the excess area is larger than a certain value, the image information will be recorded on the larger size paper. can be done.

[Example 1 FIG. 1 is a block diagram showing one embodiment of the present invention.

The facsimile apparatus according to this embodiment is configured so that three types of standard paper having the same recording width, namely, letter recording paper, A4 recording paper, and legal recording paper, can be set simultaneously. As shown in FIG. 2, each fixed-size paper has a specific length in the main scanning direction and the sub-scanning direction.

In this embodiment, the length of the received image information in the sub-scanning direction is notified from the transmitting side to the receiving side! ;L (unit lll11)
On the other hand, recording paper is selected based on the selection table shown in FIG. 3 for recording.

In other words, on letter recording paper, the length of a sentence is 282 m.
When the length is greater than or equal to +m and less than 288+uw, the received image information is reduced and recorded, and when the length is greater than or equal to 282m, no recording is performed on letter recording paper.

Also, for A4 recording paper, the length is 2881111
If the length is less than 300 mm, the received image information is recorded at the same size, and if the length is 300!1 mm or more and less than 306 mm, the received image information is recorded in a reduced size. Furthermore, if the length of the sentence exceeds 306 mm, it will not be recorded on A4 recording paper.

In addition, for legal recording paper, if the length is 306m or more and less than 359mm, the received image information is recorded at the same size, and if the length is 359m+m or more and less than 366mm, the received image information is reduced. and record it. Furthermore, if the length of the sentence exceeds 366 mm, it is recorded on two or more sheets of legal recording paper.

As described above, in this embodiment, when the excess length of the sub-scanning direction text is within a certain range for each recording paper, the received image information is reduced and recorded. In addition, if the excess length of the sub-scanning direction exceeds a certain range for letter recording paper and A4 recording paper, if the length of the sentence in the sub-scanning direction exceeds a certain range, a recording paper of a size one rank larger than the recording paper, that is, if it is letter recording paper, A4
4 recording paper, A4 recording paper, and record on Arebori Ichigal recording paper. Furthermore, in the case of legal recording paper, if the excess length of the sentence in the sub-scanning direction exceeds a certain range, recording is performed on two or more sheets of legal recording paper. In this way,
The optimal recording paper can be selected.

Each element will be explained in turn below.

In order to use the telephone network for data communication, etc., the NCU (network control unit) 2 connects to the terminal of the line, controls the connection of the telephone exchange network, switches to the data communication path, and controls the loop. It is used to maintain the Also, N

If a) is "0", the telephone line 2a is connected to the telephone 4 side, and if the signal level is rlJ, the telephone line 2a is connected to the facsimile machine side. Under normal conditions, the telephone line 2a is connected to the telephone 4 side.

The hybrid circuit 6 separates the transmission system signal and the reception system signal, sends the transmission signal from the adder circuit 20 to the telephone line 2a via the NCU 2, and transmits the signal from the other party to the NCU 2.
The signal is sent to the V29 demodulator 24 and V21 demodulator 22 via the V29 demodulator 24 and V21 demodulator 22.

The document sensor 8 is a circuit (hereinafter referred to as D) that detects the presence or absence of a document.
It includes a circuit (hereinafter referred to as DBS) that detects the leading edge or trailing edge of a document. The DS detection signal is transmitted through the signal line 8a, and the DES detection signal is transmitted through the signal line 8b.
is inputted to the control circuit 38 by.

Then, in order from the insertion direction of the document, there are DS→-DES→reading positions.

From the DES to the reading position, after the leading edge of the 7 originals, which are separated by a predetermined distance α, passes through the DBS, the leading edge of the document is moved further by a predetermined distance α+α.
′ (α′ is because the shadow line due to the leading edge of the document cannot be read), then reading starts. Further, after the trailing edge of the document passes through the DBS and is further conveyed by a predetermined distance α-α″ (α” is because the shadow line due to the trailing edge of the document is not read), reading ends.

The reading circuit 10 sequentially reads image signals for one line in the main scanning direction from a transmission document, and creates a signal string representing binary values of white and black. It consists of a system. The white and black binary signal strings are sent to the encoding circuit 12. Further, each time the control circuit 38 outputs a conveyance pulse (signal line 38b), the document is moved a predetermined distance (for example, 1/1 in the case of superfine).
i5.4m layer) at a time.

The encoding circuit 12 encodes read data (MH (Modified Huffman) encoding or MR (Modified Read) encoding).

The memory circuit 14 stores the encoded information output from the sign, %, ;fi circuit 12 and outputs the stored information to the modulator 16. This memory circuit 1
Storage and output of information to and address management of the information to and from the control circuit 38 (signal line 38C) are performed by the control circuit 38 (signal line 38C).

The V27ter or V29 modulator 16 is a known CCI
TT Recommendation V27ter (differential phase modulation) or v29 (
This is a modulator that performs modulation based on quadrature modulation. This modulator 16 receives a selection signal (
When the signal line 38d) is "0", the information output from the encoding circuit 12 is directly input for modulation, and when the selection signal is "1", the information stored in the memory circuit 14 is input. Perform modulation. The modulated output of this modulator 16 is then sent to an adder circuit 20.

The V21 modulator 18 is a modulator that performs modulation based on the well-known CCITT Recommendation 21, and modulates the procedure signal (signal line 38e) from the control circuit 38 and sends it to the addition circuit 20.

Addition circuit 20 is a circuit that adds the outputs of modulators 16 and 18 by 1. The output of the adder circuit 20 is sent to the /\ibrid circuit 6.

The V21 demodulator 22 performs demodulation based on the well-known CCITT recommendation V21. The demodulator 22 inputs the procedure signal from the hybrid circuit 6, performs V21 demodulation, and sends demodulated data to the control circuit 38.

The V27 ter or V29 demodulator 24 is a known C
Demodulation is performed based on CITT recommendation V27ter or V29. The modulated image signal from the hybrid circuit 6 is input, demodulated, and the demodulated data is sent to the decoding circuit 26.

The decoding circuit 26 is a circuit that decodes demodulated data from the demodulator 24 (MH decoding or MR decoding).

The reduction circuit 28 reduces the image signal at a predetermined reduction rate. That is, when the reduction instruction signal (signal line 38f) from the control circuit 38 is "1", the reduction circuit 28
is enabled, inputs the output image signal from the decoding circuit 26, and reduces the size in both the main and sub-scanning directions. Further, when the reduction instruction signal is "0", the reduction circuit 28 is in a disabled state and does not operate.

The selection circuit 30 selects whether to record the received image information in the same size or in the reduced size, and when the reduction instruction signal from the control circuit 38 is "0", the selection circuit 30 selects whether to record the received image information in the same size or in the reduced size. When the reduction instruction signal is rlJ, the output of the reduction circuit 28 is selected. This selected image information is then sent to the recording section 40.

The recording unit 40 sequentially records the decoded white and black signals output from the decoding circuit 26 line by line.

As described above, the letter recording paper 32, the A4 recording paper 34, and the legal recording paper 36 can be set in the recording section 40, and these can be selected to perform the recording operation.

That is, the letter recording paper selection signal from the control circuit 38 (
When the signal line 38g) is rlJ, recording is performed on letter recording paper. Then, based on a recording paper exchange pulse (signal line 38j) from the control circuit 38, the paper currently being recorded is ejected, and recording is performed on the next cut paper. Furthermore, when the letter recording paper selection signal is "0", no recording is performed on the letter recording paper.

Also. A4 recording paper selection signal from the control circuit 38 (signal &
138 When h) is rlJ, recording is performed on A4 recording paper. Then, based on the recording paper exchange pulse from the control circuit 38, the cut paper currently being recorded is ejected, and recording is performed on the next cut paper.

Furthermore, when the A4 recording paper selection signal is "0", the A4 recording paper selection signal is "0".

Further, the control circuit 38 sends a glue-gal recording paper selection signal (
When the signal line 381) is "1", recording is performed on legal recording paper. Then, based on the recording paper exchange pulse from the control circuit 38, the cut paper currently being recorded is ejected, and recording is performed on the next cut paper. Furthermore, when the legal recording paper selection signal is "0", no recording is performed on legal recording paper.

4. The control circuit 38 controls each of the circuits already described, and
It performs overall control of this facsimile machine.

FIG. 4 is a flowchart showing the operation of such a facsimile machine.

First, execute the initial routine. In other words, CM

), the reduction circuit 28 is disabled 546),
The select circuit 30 is set to a mode for direct input from the decoding circuit 26 (348). Also, regarding the recording section 40, the initial state is S50.5 in which letter recording paper is selected.
52), wait for instructions such as sending or receiving (854-55
8).

Next, when memory transmission is instructed (S54), first,
After setting the page counter to "1" and the line counter to "0" (S60.562), the image is read and stored in the memory circuit 14 while counting the number of lines.
64-868). Then, when the processing of one page is completed, divide the number of lines by a constant depending on the reading mode and calculate the length n of the document in the sub-scanning direction.
(Ilm) is determined (S70).

Then, the value of the length counter is stored together with the document size in accordance with the page counter (572), and if there is next reading information (S73), the page counter is incremented (S74), and the next information is read.

When the reading is completed, a call is made to the designated party (S76), the CML is turned on (S78), and the pre-procedure is performed (S80).

Here, for example, if the length of the recording paper of the other machine in the main scanning direction is A
4, the length of the reading information (transmission document) in the main scanning direction is B4.
If so, the reduced transmission from B4 to A4 is performed, so the length counter corresponding to the page counter is set to a value multiplied by 9i11 (S82 to 586). That is, here, it is important to consider not the length in the sub-scanning direction at the stage of transmission, but the length in the sub-scanning direction after it is actually sent onto the transmission path from the sending side. Of course, in this case, information in the main scanning 6 direction is also reduced from B4 to A4.

Then, the length of the transmitted image information in the sub-scanning direction corresponding to the page counter is notified to the receiver using a procedure signal (388).
, the remaining pre-procedures are performed (S90), the modulator 16 is set to a mode for inputting from the memory circuit 14 (S92), image transmission is performed (S94), and after the post-procedure is completed (S96), the process returns to the initial routine.

Next, the operation at the time of reception will be explained.

First, turn on CML (39B) and perform the previous procedure (si
oo), the length in the sub-scanning direction is stored in correspondence with the page counter (S102). Next, set the page counter to “1”
5i04), enter the length l (am) in the sub-scanning direction that is stored corresponding to the page counter above, and select whether it is letter printing, A4 printing, or legal printing based on the table shown in Figure 3. Decide whether to further reduce the size or not. Based on this decision,
Recording is performed by controlling the recording paper selection signal and the reduction instruction signal, and after the recording of one page is completed, a recording paper exchange pulse is output (s i O6). Here, when the length of the sentence in the sub-scanning direction is 366 mm or more, it is divided into two or more pages, so the recording paper exchange pulse is generated at least twice.

Furthermore, if there is next information, the page counter is incremented (Silo) and the next information is recorded, and if there is no next information, a post-procedure is performed (S112) and the process returns to the initial routine.

In the above embodiment, when reducing the image information for each standard paper, the reduction rate is fixed, but the reduction is done according to the ratio of the length of each standard paper and the image information in the sub-scanning direction. The rate may be varied.

Further, in the above embodiment, information regarding the length in the sub-scanning direction is notified from the transmitting side, but the length in the sub-scanning direction may be detected by receiving the information in the memory on the receiving side.

Furthermore, instead of notifying the length in the sub-scanning direction in the pre-procedure as described above, it may be notified immediately before each page is transmitted.

Furthermore, in the above embodiment, a case was explained in which the lengths of the transmitted image information in the main scanning direction are equal; however, since A4 size and B4 size are mixed in the read information on the transmitting side, It can be similarly applied to cases where the length in the direction changes.

Effect of the Invention 1 According to the present invention, when image information that exceeds the standard size recording paper is received, the image information is reduced and recorded, and the image information is divided into two cut sheets. Opportunities for recording can be reduced, and recording paper can be used more effectively.

In addition, when setting multiple standard sizes at the same time, if the excess area is larger than a certain value, the image information will be recorded on a larger size cut paper, so choose the recording paper appropriately. be able to.
