Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile device, and more particularly to a facsimile device with improved recording paper usage efficiency.

[Prior art] In conventional facsimile machines, during pre-transmission procedures, etc.
The size of the recording paper on the image receiving side is notified to the transmitting side, and transmission control is performed based on this.

For example, if the size of the recording paper on the receiving side is longer than or equal to the width of the set document, the transmitting side device transmits the original size. Furthermore, if the width of the recording paper size is narrower than the original, the image is reduced and sent.

On the other hand, many recent facsimile machines are configured to transmit documents ranging from 15OBB size to A3 size, which causes the following problems.

Assume that the recording paper width of the receiving facsimile device is 210 mm (that is, the length of the short side of A4 paper), and the length is not limited because roll paper is used. If an attempt is made to send a document smaller than A4, for example, A5, to such a device, a blank space will be created on the recording paper, resulting in waste and the transmission time will increase.

This situation is shown in FIGS. 1(A) and 1(B).

In FIG. 1A, reference numeral 1 indicates an A5-sized document to be transmitted, and reference numeral 2 indicates a recording paper having the width of the short side of A4 on the receiving side. In the conventional method, since the original size is smaller than the recording paper, the original size is transmitted at the same size. Therefore, as shown in FIG. 1(B), the image is recorded □ on the recording paper 2 as shown by the reference numeral 3, □ a wasteful margin is created on the recording paper, and the scanning is performed only in the first scan.
Since the transmission is carried out in the direction shown by the arrow in FIG.

Furthermore, even if the document 4 shown in Fig. 2 (A) is A4 size, it is set horizontally as shown in the figure, and the recording paper on the receiving side is on the A4 short side as in Fig. 1 (B). If the width is too wide, there is also the drawback that unnecessary reduction transmission is performed. In this case, the recording paper 5 on the receiving side is shown in Fig. 2 (B
), an image 6 reduced in the horizontal position is recorded.

1 [Objective] The present invention has been made in view of the above points, and it is an object of the present invention to provide a facsimile machine that can use recording paper on the receiving side without wasting it and that requires short transmission time.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

First, Figure 3 (A), (B) and Figure 4 (:A), (
The principle of the present invention will be explained with reference to B).

FIGS. 3A and 3B show the transmission performed according to the present invention in the case shown in FIGS. 1A and 1B.

That is, what is indicated by the symbol l in FIG. 3(A) is an A5 size document, which is set in the transmitter in a vertical position. In the present invention, when the original is set in this way and the recording paper 2 on the receiving side has the width of the short side of A4 paper, the image information of the original is rotated approximately 90 degrees as shown by the arrow P, and the image information 7 is Transmit as.

This result record is A5 as shown by reference numeral 8 in Fig. 3(B).
This records the horizontal position. As is well known, A5 size is exactly half of A4 size, so image information 8 fits exactly within the width of the short side of A4. In this case, since the image information is transmitted in the direction of the short side of A5, the actual transmission time can be shorter than in the case of FIGS. 1(A) and CB).

Further, FIGS. 4(A) and CB) show the transmission performed according to the present invention in the cases shown in FIGS. 2(A) and (B).

As shown in FIG. 4(A), when the A4 original 4 is set in the horizontal position and the recording paper 5 on the receiving side has the same width as above, the image information of the original 4 is As shown in , the image is rotated approximately 90 degrees and nine pieces of image information are transmitted. As a result, image information lO is recorded on the recording paper 5 on the receiving side, as shown by reference numeral 10, in the same manner as in normal vertical transmission. This eliminates unnecessary reduction transmission.

A more detailed example will be shown below, but here the width of the recording paper on the receiving side is 210+sm, that is, the length of the short side of A4 paper, and the length is assumed to be roll paper, etc., and there is no limit. do.

In addition, in this embodiment, the width of the original that can be set is mechanically 148 mm or less, exceeding 148 +++ m and 210 all.
Below, there are four categories: over 210g1m and under 257l1ss, and over 257cm and under 297cm. These document sizes are checked by a sensor. Further, the set length of the document is determined by counting the number of scanned main scanning lines.

The facsimile machine according to the invention is provided with a large capacity image memory, and image information is stored in this memory prior to transmission of the original document. By examining this image information, the size of the document including its length can be recognized in advance.

Then, if the recording paper width on the receiving side is the length of the short side of A4, and the original is A4 or A5, the main scanning length is 2.
If necessary, the image information is rotated and transmitted so that the length of the short side of A4 paper is 10 mm. Rotation is performed by changing the way image information is read from memory.
In the case of 3 and B4, reduction is performed as in the conventional case.

Also, if the recording paper width on the receiving side is the length of the short side of B4 and the original is A4 or A5, the main scanning length is similarly reduced to 2105 m and transmission is performed.
If the size is A3, the image information is transmitted at the same size, and if it is A3 size, it is reduced.

Finally, the recording paper width is the length of the short side of A3, and the original is A5.
If the size is the same, image information is sent so that the main scanning length is 210 mm. If the original is A4 size, image information is sent so that the main scanning length is 297 am. If the document is B4 size or A3 size, it is transmitted at the same size.

In the case of a long original, the image information of the original is transmitted in the same direction as it is set, that is, no rotation is performed.

FIG. 5 is a block diagram showing the configuration of a facsimile machine employing the present invention.

In FIG. 5, reference numeral 12 indicates an original width detection circuit for detecting the width of the set original.

The document width detection circuit 12 detects when the width of the document corresponds to the length of the short side of A5 size (that is, exceeds 148+sm and exceeds 210 mm).
+i+s or lower), the signal level r is applied to the signal line 12a.
Output lJ. In addition, the document width detection circuit 12 detects cases where the width of the document is equivalent to the length of the side of B4 (exceeding 210 mm and 257 m).
m or less), the signal level “1,” is applied to the signal line 12c.
Output. Further, when the document width corresponds to the short side of A3 paper, a level "1" is output to the signal line 12d. This circuit can be composed of a photointerrupter provided at a predetermined location on the document table, a logic circuit, and the like.

Each of the above signals is input to a control circuit 21, which will be described later.

Further, 13 indicates a circuit for detecting a 015 signal (digital identification signal) transmitted from the facsimile machine on the image receiving side. When the DIS signal detection circuit 13 detects the DIS signal from the other party, it generates a pulse on the signal line 13c. Further, the DIS signal detection circuit 13 detects information on the recording paper size included in the FIF (facsimile information field) of the DIS signal. DIS signal detection circuit 13
outputs information on the 17th and 18th bits of the FIF of the DIS signal to signal lines 13a and 13b, respectively. If the 17th and 18th bits of information are both rQJ, the recording paper of the other party's facsimile machine is A4 width, that is, 210 m.
It is m. If the 17th bit is “1”, the width is 84 (25
7am) *If the 18th bit is rlJ, the recording paper is 3mm wide. Each detection signal is similarly output to the control circuit 21.

The received signal is sent via a transmission path 23a such as a telephone line, inputted into the hybrid circuit "22" via a well-known network control device 23 and a signal line 22a, and separated from the transmitted signal.
The signal is input to the IS signal detection circuit 13.

The reference numeral 14 is a part of a known scanner configured using a CCD sensor or the like, which reads image information for l lines in the main scanning direction, and outputs a black and white binary image signal sequence to the signal line 1.
It is output to the control circuit 21 via 4a. After reading the l line, the scanner part 14 reads the signal line 14b.
generates a pulse.

Also, numeral 15 is a line counter, which is a control time.

Each time a pulse is generated on the signal line 21a of the line 21, the count value is incremented by one. Further, when a pulse is generated on the signal line 21b, the count value is cleared. The count value is output to the signal line 15a.

Further, a DC3 signal sending circuit 16 is provided as a transmission system circuit. The DC3 signal sending circuit 16 is connected to the signal line 21
When a pulse is generated by the control circuit 21 at c, a DO5 signal (digital command signal) is output to the adder circuit 2-0 via the signal line 18a. The 17th and 18th bits of the PIF of the DO3 signal are sent to the control circuit 21.
are output to signal lines 21 d and 2.1 e, respectively. If the document width is A4, signal lines 2.1d and 21
A level "0" is output to both lines e, and in the case of B4, a level "1" is output to the signal line 21d, and a level "0" is output to the signal line 21e. Furthermore, when the document width is A3, level "0" is output to both signal lines 21d and 21e.

The transmitted DO3 signal is added to a control signal of another signal sending circuit (not shown) or an image signal (described later) in an adder circuit 20, and then sent to the hybrid circuit 22 via a signal line 20a.
is input to the signal line 22a and the network control unit (NCU).
) 23 to the transmission line 23a.

Further, reference numeral 17 is the memory for image information mentioned earlier, into which image information read by the scanner part 14 before the start of transmission is inputted via the control circuit 21 and stored therein. The data read from the original is sent to the control circuit 21. The signal is input to the memory 17 via the signal line 21f.

The state of data storage in the memory 17 is schematically shown in FIG. 6. In the figure, the arrow Q indicates the direction in which the lower address increases, and the arrow R indicates the direction in which the upper address increases. As shown by M3, the data is stored one line at a time in order from the one with the highest address. Each line is stored in order from the lowest address to the lowest.

When the memory 17 completes preparation for data storage, it generates a pulse on the signal line 17a to notify the control circuit 21.

One piece of information read from the signal line 17a is input to an encoder 18 using a known method such as MH (Modify Huffman) or MR (Modify Read) and is encoded. The encoder 18 is connected to the signal line 21g output from the control circuit 21.
When this signal is at level "0", data is sequentially read out from the memory 17 in the direction of arrow Q in FIG. 6 and inputted. When the signal line 21g is at level "L", data is read from the memory 17 in the direction of arrow R in FIG. Then, the lower address is incremented and fixed, and the upper address is similarly incremented by 1 and read out, thereby rotating the image information by approximately 90 degrees.

The encoded image information is sent to the modulator 19 via the signal line 18a.
is output to.

The modulator 19 is a known modulator that performs phase modulation or quadrature modulation on the signal on the signal line 18a and outputs it to the adder circuit 20 via the signal line 19a. This modulated image signal is output to the transmission path 23a via the hybrid circuit 22 and network control device 23 in the same manner as described above. - A read original detection circuit 24 is further connected to the control circuit 21. This detection circuit is also a known detection circuit composed of a photointerrupter or the like, and when there is a document to be transmitted at a predetermined position, a level rlJ is applied to the signal line 24a.
However, if there is no original, the level rOJ is output to the signal line 2°4a.

The control circuit 21 is composed of a microprocessor or peripheral memory elements, and is programmed with control as outlined below.

Prior to image transmission, the control circuit 21 first reads the image information of the document using the scanner part 14 and writes it into the memory 17. Here, for ease of explanation, it is assumed that the memory storage time is shorter than the reading time, and that high-quality transmission is not performed but only standard transmission is performed.

When reading an image, a line counter 15 is used to count how many lines of data have been read. Set this number of lines to the sub-scanning line density (for example, 3.85 lines/mm)
By dividing by , the length of the document in the sub-scanning direction is recognized.

Also, the recording paper width of the other party is determined by the above-mentioned DIS signal detection circuit 1.
Recognized by 3. Once the sizes of the original and recording paper are known, it can be determined whether to transmit them in the set direction or rotate them.

This determination method will be explained with reference to FIG. - In FIG. 7, symbol X indicates a document or recording paper, and arrow U indicates the direction of conveyance of the document, that is, the direction opposite to the sub-scanning direction.

If the length of the document in the S direction is equal to the width A of the recording paper,
The image information of the original is transmitted at the same magnification in the same direction as it is set.

Also, if the length in the S direction is shorter than the recording paper width A (unless the length of the document in the T direction is equal to or longer than the length in the S direction), the image information of the document is set in the set direction. On the other hand, it is rotated approximately 90 degrees and transmitted at the same magnification. Also, if the length of the original in the T direction is equal to or shorter than the length of the original in the S direction, or if the length of the original in the T direction exceeds the recording paper width A, set the image information of the original. Transmit at the same magnification in the same direction.

Finally, the case where the length in the S direction exceeds the width A of the recording paper will be described. In this case, if the length of the document in the T direction is less than or equal to the width A of the recording paper, the image information of the document is rotated approximately 90 degrees with respect to the set direction and transmitted at the same size. Also,
If the length of the document in the T direction exceeds the width A of the recording paper, the image information of the document is reduced and transmitted in the set direction.

The length of the main scanning line obtained by rotating approximately 90 degrees is reported to the receiving device using the PIF of the DO3 signal.

FIGS. 8(A) to 8(F) show detailed flowcharts of the control procedure of the control circuit 21 described above.

However, in FIGS. 8(A) to 8(F), the portions with the same reference numerals are assumed to be connected to each other.

In step S30 of FIG. 8(A), the control circuit 21 generates a pulse on the signal line 21b, that is, initializes the count value of the line counter 15 to "0".

Next, in step 531, it is determined whether a pulse has been generated on the signal line 14b, that is, whether reading of one line has been completed. If reading is completed, step S32
Proceed to. The image is read by driving a known document conveyance system one line at a time.

In step 332, the signal on the signal line 14a is input, that is, one line's worth of binary image signal string is input.

In step 333, it is determined whether a pulse has occurred on the signal line 17a, that is, whether the memory 17 can store one line of data. If the preparation of the memory 17 is completed, the process advances to step 334.

In step 334, the image signal string for one line inputted in step 332 is outputted to the signal line 21f.

In step 335, a pulse is generated on the signal line 21a, that is, the count value of the line counter 15 is increased by one.

In step S36, it is determined whether the signal level of the signal line 24a is "1", that is, whether or not the document is present at the reading position. If a document exists, the process advances to step S31 to read the next line.The document is finished and the signal line 24a is at level rOJ17).

Steps S37 to S39 are the document width detection circuit 1.
In this step, the width of the document set on the document table is determined by checking the output of step 2.

In steps 337 to 339, the signal lines 12a and 1
It is determined whether or not 2b and 12c are at level "1".

If the signal line 12a is at level rlJ, that is, if the document width is the short side of A5, the process moves to step 340 in FIG. 8(B). If the signal line 12b is at level rlJ and the document width is the length of the short side of A4 paper, the process moves to step 351. In addition, when the signal line 12c is at level "1" (when all the signal lines 12a to j2c are at "O"), ``In other words, when the document width is the length of the short side of B4, The process advances to step 373.

Steps S40 to 550 in FIG. 8(B) are as follows:
This routine checks the length of the document in the sub-scanning direction when the width of the document is A5 on the short side by checking the count value of the line counter 15 of the signal line 15a. Here, 3.85 lines/m+a is considered as the sub-scanning line density.

In step 340, if the number of signal lines 15a is 570 mm or less, that is, if the length of the document in the sub-scanning direction is 148 mm or less considering the sub-scanning line density, the process proceeds to step 345, and the control device 21 registers the own register B. (or memory may be used), and store ri IJ in

Similarly, in step 341, if the signal line 15a is 809 or less, that is, the length of the document in the sub-scanning direction is 210 m.
If it is less than m, "12" is stored in the B register (step 346), and the process moves to step 3B4.

Further, if the signal line 15a is 989 or less in step 342, that is, the length of the document is 257 m+a or less, "13" is stored in the B register in step S47, and step 38
Proceed to step 4.

Furthermore, step 343 + signal line 15a is 1143 or less,
In other words, if the length of the manuscript is less than 297cm, "14" is stored in the B register in step 348, and in step 38
Proceed to step 4.

Also, in step 344, if the signal line 15a is 1617 or less,
In other words, if the length of the original is 420 mm or less, "15" is stored in the B register in step 347, and "15" is stored in the B register in step 38.
Proceed to step 4.

If all of the above steps are negative, that is, if the signal on the signal line 15a exceeds 1617 and the length of the document exceeds 420m+a, the B register is set to "1617".

Subsequently, in steps 392 and 393, "0" is output to the signal lines 21d and 21e, respectively, and a DC3 signal containing information that the main scanning line length is A4 is sent out. DO3
The signal is sent by generating a pulse on the signal line 21c in step S94. Then, in step 395, transmission at the same magnification and without rotation is performed.

Step 5102 and subsequent steps in FIG. 8(E) are for the case where the recording paper width on the receiving side is B4 size.

In steps 5L02 to 5105, the contents of the B register are determined as described above.

In steps 3102 to 3104, the contents of the B register are “3”.
If it is any one of “1” to “36”, step 31

In step 3106, a signal of level "1" is output to the signal line 21g, that is, the image information of the original is controlled to be rotated approximately 90 degrees with respect to the set direction.

Next, in steps 5107 and 3108, the signal lines 21e and 2
A level "0" is output to 1d, and information indicating that the original size of this document is A4 is placed on DC3C10PIF.

Subsequently, in step 3109, the contents of the B register become "31".
” to “34”, “13”, “23”, and “43”. If this step is denied, the process jumps to step 5tti.

Stella 7"5llO outputs a level "1" to the signal line 21d and sends information that the document size is B4 to the DC3C.
Put 10 on it.

In step 5ill, a pulse is generated on the signal line 21c,
Sends the DO3 signal.

Next, in step 3112, same-size transmission is performed, and here, if the step 510B has been passed, approximately 90
Transmission at the same magnification and rotated by a degree is performed. On the other hand, step 5
113, and when level "0" is output to the signal line 21g, equal-size transmission without rotation is performed.

In step 5114, the level “0” is applied to the signal line 21g.
" signal is output. That is, no rotation is performed.

In steps 3115.5l16, each signal line 21e
, level rlJ, "0" is output to the signal line 21d, and information indicating that the document size is B4 is placed on the DC3C10FIF.

In step 3117, a pulse is generated on the signal line 21c,
The DC3C10 transmission is performed, and then reduced transmission is performed in step 5118. Here, the image information of the original is transmitted in reduced size in the set orientation without being rotated.

Step 386 after step 3119 in FIG. 8(F)
This is the process when the recording paper width of the other party is A3.

In steps 5119 to 3122, the value of the B register is checked as described above.

In step 3119, the contents of the B register are "41" to "4".
6'', the process moves to step 5130.

In steps 5120 and 3121, the contents of the B register are rlIJ, "15", r16J, or "2".
If it is any one of ``1'', ``22'', ``25'', and ``26'', the process moves to step 5133.

In step 3122, the contents of the B register are set to "31" to "3".
If it is any one of ``3'', ``35'', and ``36'', the process moves to step 5136.

If all of steps 511-9 to 5122 are negative, the process moves to step 5123.

In step 3123, the signal level rlJ is output to the signal line 21g, that is, the image information of the original is rotated approximately 90 degrees with respect to the set direction and read out from the memory 17.

In steps 5124 and 5125, the signal lines 21d and 21e
It outputs the level rQJ to , and puts the fact that this document is λ4 size on the PIF of the DO5 signal.

In step 3126, it is determined whether the contents of the B register are between "13" and "23". If this step is affirmative, the process moves to step 5139, outputs level "1" to the signal line 21d, rewrites the information regarding the original in the FIF of the DC5 signal to indicate a B4 original, and moves on to step 5128.

If step 5126 is negative, step 312
7, the contents of the B register are "14", "24",
It is determined whether it is one of "34". If this step is negative, the process moves to step 5128, and if it is positive, level rlJ is output to the signal line 21e in step S L40, and the document size information of the PIF of the DO3 signal is changed to indicate an A3 document. After rewriting it, the process moves to step 3128.

In steps 3130, 5133, and 5136, level "0" is output to the signal line 21g, respectively.

This allows transmission without rotation.

In steps 5131 and 5132, each signal line 21d
, 21e are output with level "O" and rlJ, and information indicating the A3 size is written in the document size area of the FIF of the DC5 signal, and then the process moves to step 8128.

In steps 5134 and 5135, each signal line 21d
, 21'e is output with level r'QJ, "0", and D
After writing information indicating the A4 size in the document size area of the PIF of the O3 signal, the process moves to step 3128.

In steps 5137 and 5138, the signal line 21d
, 21e is output with level rl'J, "0", and DC3
After writing information indicating the B4 size in the C10FIF original size area, the process moves to step 5L2B.

In step 8128, a pulse is generated on the signal line 21c,
DC to which document size information has been written as described above
Issue 5Q will be sent out.

Subsequently, in step 3129, same-size transmission is performed. If the image information has passed through step 3123, the image information rotated by approximately 90 degrees is transmitted at the same size, and step 5130.5133
If the signal passes through 5136 and 5136, same-size transmission without rotation is performed.

As described above, the image information is rotated if necessary according to the size of the recording paper on the receiving side, and the image information is transmitted at the same size or reduced in size, thereby preventing waste of recording paper and shortening the transmission time.

Since the image information is stored in the memory in advance, when rotation is performed, the image information transmission time in the sub-scanning direction can be shortened compared to when the image information is sent directly, so the transmission time can be shortened, for example. Recording paper strength] In the case of A4 width and A5 document in portrait position, the image information is rotated approximately 90 degrees, and is recorded in horizontal position on the receiving side. Also, the recording paper width is A4,
If the original is A4 in landscape orientation, the image information is rotated, and the image information is recorded in portrait orientation on the receiving side.

If the document is in the horizontal position (54ir), the image information is further reduced.

In the embodiments described above, the image information is rotated by changing the direction in which the image information is read from the memory, but the document may also be mechanically rotated by rotating the document table or the like. According to this, the capacity of the image memory can be reduced. Further, in the above embodiment, the DIS and DO3 signals conforming to the CCITT (International Telegraph and Telephone Consultative Committee) recommendation T30 were exemplified; However, it goes without saying that the present invention can be implemented in the same manner.

[Effects] As is clear from the above description, according to the present invention, the advantages of the means for recognizing the recording paper size on the receiving side, the means for recognizing the size of the image information of the original, and the re-recognition means described above are achieved. The image information of the document is rotated approximately 90 degrees and transmitted according to the size of the recording paper and image information to be transmitted.
It is possible to provide an excellent facsimile device that can prevent waste of recording paper and shorten transmission time.
