Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for performing image processing on a read original image and transmitting the image-processed image to another facsimile apparatus.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus, the size of a recording sheet on the image receiving side is notified to the transmitting side in a pre-transmission procedure or the like, and transmission control is performed based on this.

For example, when the size of the recording paper on the receiving side is longer than or equal to the width of the set original, the transmitting side device transmits data in its original size. If the width of the recording paper size is narrower than the original, the image is reduced and transmitted.

On the other hand, in recent facsimile machines, the ISO
Since many of them are configured to transmit originals of B6 size to A3 size, there are problems as described below.

The receiving side facsimile device has a recording paper width of 21.
It is assumed that 0 mm (that is, the length of the short side of A4) and the length is not limited because roll paper or the like is used. If an original document having a size smaller than A4, for example, an original document having an A5 size is transmitted to such a device, a blank space is generated on the recording paper, which is wasted, and the transmission time becomes long.

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

Here, reference numeral 1 in FIG. 1 (A) is an A5 size original to be transmitted, and reference numeral 2 is a recording paper having a width of the short side of A4 on the receiving side. In the conventional method, the size of the original is smaller than that of the recording paper, and therefore transmission is performed at the same size. Therefore, as shown in FIG. 1 (B), the image is recorded on the recording paper 2 as indicated by reference numeral 3, and a useless margin is generated on the recording paper, and the scanning is performed by the arrow in FIG. 1 (A). Since it is performed in the direction shown by, the transmission time will be long.

Further, even if the original 4 shown in FIG. 2 (A) is A4 size, it is set in the horizontal position as shown and the recording paper on the receiving side is the A4 short side as in FIG. 1 (B). However, there is also a drawback that unnecessary reduction transmission is performed when the width is within the range. In this case, the image 6 reduced in the horizontal position is recorded on the recording paper 5 on the receiving side as shown in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in the drawings.

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

FIGS. 3A and 3B are shown in FIGS. 1A and 1B.
3 shows the transmission carried out according to the invention in the case shown in FIG.

That is, the reference numeral 1 in FIG. 3 (A) is an A5 size document, which is set in the transmitter in a vertical position. In the present invention, the original is set in this way,
When the recording paper 2 on the receiving side has a width of A4 short side, the image information of the original is rotated by about 90 degrees and transmitted as image information 7 as indicated by an arrow P.

As a result, the recording is the recording at the A5 lateral position as indicated by reference numeral 8 in FIG. As is well known, the A5 size is exactly half of the A4 size, so the image information 8 is exactly A4.
Fits within the width of the short side of. In this case, the actual transmission time is A
Since the image information is transmitted in the direction of the short side of FIG.
It can be shortened as compared with the case of (B).

Further, FIGS. 4A and 4B are shown in FIGS.
FIG. 7B shows the transmission performed by the present invention in the case shown in FIG.

As shown in FIG. 4A, when the original 4 of A4 is set in the horizontal position and the recording paper 5 on the receiving side has the same width as the above, the image information of the original 4 is displayed. The image is rotated by approximately 90 degrees as indicated by an arrow P and transmitted as image information 9. As a result, as indicated by reference numeral 10, the image information 10 is recorded on the recording paper 5 on the receiving side in the same manner as in normal vertical position transmission. As a result, unnecessary reduction transmission is not performed.

A more detailed embodiment will be shown below. Here, the width of the recording paper on the receiving side is 210 mm, that is, the length of the short side of A4, and the length is roll paper, and there is no limitation. I shall.

Further, the width of the original that can be set in this embodiment is mechanically less than 148 mm and exceeds 148 mm.
There are four categories: 0 mm or less, 210 mm to 257 mm or less, and 257 mm to 297 mm or less. These document sizes are checked by the sensor. The set length of the original is determined by counting the number of main scanning lines scanned.

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

When the recording paper width on the receiving side is the length of the A4 short side, and the originals are A4 and A5, the main scanning length is required to be the length of the A4 short side of 210 mm. In that case, the image information is rotated and transmitted. The rotation is performed by changing the method of reading the image information from the memory. When the originals are A3 and B4, reduction is performed as in the conventional case.

When the width of the recording paper on the receiving side is the length of the short side of B4 and the originals are A4 and A5, the main scanning length is similarly 210 mm for transmission. When the original is B4 size, it is scaled, and when it is A3 size, it is reduced and image information is transmitted.

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

In the case of a long original, transmission is performed in the direction in which the image information of the original is set. That is, no rotation is performed.

FIG. 5 is a block diagram showing the structure of a facsimile apparatus adopting the present invention.

In FIG. 5, the reference numeral 12 designates an original width detecting circuit for detecting the width of the set original. The document width detection circuit 12 outputs a signal level "1" to the signal line 12a when the document width corresponds to the length of the short side of the A5 size (that is, 148 mm or less). Further, when the width of the document corresponds to the length of the short side of the A4 size (when it exceeds 148 mm and 210 mm or less), the signal level "1" is output to the signal line 12b. Further, the document width detection circuit 12 outputs a signal level "1" to the signal line 12c when the document width corresponds to the length of the short side of B4 (more than 210 mm and less than 257 mm). When the document width corresponds to the short side of A3 (exceeds 257 mm and is 297 mm or less), the level "1" is output to the signal line 12d.
This circuit can be composed of a photo interrupter provided at a predetermined position on the platen, a logic circuit, and the like. Each of the above signals is input to the control circuit 21 described later.

Reference numeral 13 is a circuit for detecting the DIS signal (digital identification signal) transmitted from the facsimile apparatus on the image receiving side. DIS signal detection circuit 1
3 detects the DIS signal from the other side, the signal line 13
Generate a pulse on c. Further, the DIS signal detection circuit 13
Is the FIF (facsimile information field) of the DIS signal
The information on the recording paper size included in is detected. The DIS signal detection circuit 13 outputs the 17th and 18th bits of the FIF of the DIS signal to the signal lines 13a and 13b, respectively.
When the information of the 17th bit and the information of the 18th bit are both "0", the recording paper of the facsimile apparatus on the other side has an A4 width, that is, 210 mm. When the 17th bit is "1", the width is B4 (257 mm), and when the 18th bit is "1", the recording paper is A3 width. Each detection signal is similarly output to the control circuit 21.

The received signal is sent through a transmission line 23a such as a telephone line, is input to the hybrid circuit 22 through a well-known network control device 23 and a signal line 22a, is separated from the transmitted signal, and is detected by the DIS signal detection circuit 13 Entered in.

A reference numeral 14 is a known scanner unit constituted by using a CCD sensor or the like, which reads image information for one line in the main scanning direction and outputs a monochrome binary image signal string through a signal line 14a. It outputs to the control circuit 21 via the. 1
When the reading of the line is completed, the scanner unit 14 generates a pulse on the signal line 14b.

Reference numeral 15 is a line counter, which increments the count value by 1 every time a pulse is generated in the signal line 21a of the control circuit 21. 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.

A DCS signal transmission circuit 16 is provided as a transmission system circuit. DCS signal transmission circuit 16
When a pulse is generated on the signal line 21c by the control circuit 21, the DCS signal (digital command signal) is output to the addition circuit 20 via the signal line 16a.
The signals of the 17th and 18th bits of the FIF of the DCS signal are output to the signal lines 21d and 21e by the control circuit 21, respectively. If the document width is A4, the signal lines 21d, 21
The level "0" is output to both e, the level "1" is output to the signal line 21d and the level "0" is output to the signal line 21e in the case of B4. When the document width is A3, the level "0" is output to both the signal lines 21d and 21e.

The DCS signal to be transmitted is added to a control signal of another signal sending circuit (not shown) or an image signal which will be described later in the adding circuit 20, and is input to the hybrid circuit 22 via the signal line 20a. It is output to the transmission line 23a via the signal line 22a and the network control unit (NCU) 23.

Further, reference numeral 17 is a memory for the image information mentioned above, and the image information read by the scanner section 14 before the start of transmission is inputted through the control circuit 21 and accumulated. The data read from the document is input to the memory 17 via the control circuit 21 and the signal line 21f.

A data storage state in the memory 17 is schematically shown in FIG. In the figure, an arrow Q indicates a direction in which the lower address increases, and an arrow R indicates a direction in which the upper address increases. The image information is stored line by line in order from the one having the highest upper address, as indicated by symbols M1 to M3. Each line is stored in order from the smallest lower address.

When the memory 17 is ready for data storage, it generates a pulse on the signal line 17a to generate a pulse in the control circuit 2.
Notify 1.

The image information read from the signal line 17a is input to the encoder 18 by a known method such as MH (Modified Huffman) or MR (Modified Read) and is encoded. The encoder 18 inputs the signal on the signal line 21g output from the control circuit 21, and when the signal is at level "0", the data is sequentially stored in the memory 17 in the direction of arrow Q in FIG.
Read from and input. When the signal line 21g is at level "1", the memory 1 is moved in the direction of arrow R in FIG.
Read data from 7. That is, the lower address is fixed and the upper address is sequentially incremented, and when the upper address ends up, the lower address is incremented, and the lower address is fixed and the upper address is similarly incremented by 1 to read out, and the image information of about 90 Perform a degree rotation.

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

The modulator 19 is a known modulator, and the signal line 18
The signal a is phase-modulated or quadrature-modulated and output to the addition circuit 20 via the signal line 19a. This modulated image signal is output to the transmission line 23a via the hybrid circuit 22 and the 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 well-known detection circuit composed of a photo interrupter or the like. When the document to be transmitted exists at a predetermined position, the signal line 24a has the level "1", and when there is no document, the signal line 24a. The level "0" is output to.

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

Prior to image transmission, the control circuit 21 first reads the image information of the document by the scanner section 14 and writes it in the memory 17. For ease of explanation,
The memory storage time is shorter than the reading time, and high-quality transmission is not performed, but only standard transmission is performed.

When reading an image, the line counter 15 is used to count the number of lines of data read. The length of the document in the sub-scanning direction is recognized by dividing the number of lines by the sub-scanning line density (for example, 3.85 lines / mm). Further, the width of the recording paper on the other side is recognized by the DIS signal detection circuit 13 described above. If the sizes of the original and the recording paper are known, it is possible to determine whether the transmission should be performed in the set direction or the rotation should be performed.

This determination method will be described with reference to FIG.

Reference numeral X in FIG. 7 denotes an original or recording paper,
An arrow U indicates the document conveyance direction, that is, the direction opposite to the sub-scanning direction.

When the length of the original document in the S direction is equal to the width A of the recording paper, the image information of the original document is transmitted at the same size in the set direction.

When the length in the S direction is shorter than the recording paper width A (except when the length of the document in the T direction is equal to or shorter than the length in the S direction), the image information of the document is set. The signal is rotated approximately 90 degrees with respect to the horizontal direction and transmitted at the same size. If the length of the document in the T direction is equal to or shorter than the length of the document in the S direction, or if the length of the document in the T direction exceeds the recording paper width A, the image information of the document is set. It is transmitted at the same size as it is.

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 by 90 degrees with respect to the set direction and transmitted at the same size. If the length of the document in the T direction exceeds the width A of the recording paper, reduction transmission is performed in the direction in which the image information of the document is set.

The length of the main scanning line obtained by rotating about 90 degrees is notified to the receiving side device by using the FIF of the DCS signal.

8 to 13 are flow charts showing the control procedure of the control circuit 21 in detail. However, in FIGS. 8 to 13, the portions denoted by the same reference numerals are connected to the respective flows.

In step S30 of FIG. 8, 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 S31, it is determined whether or not a pulse has occurred on the signal line 14b, that is, whether or not the reading of one line has been completed. When the reading is completed, the process proceeds to step S32. The reading of the image is performed by driving a known document conveying system for each line corresponding to one line.

In step S32, the signal on the signal line 14a is input, that is, the binary image signal string for one line is input.

In step S33, the signal line 17a
Pulse is generated, that is, whether the memory 17 can store one line of data is determined. Memory 1
When the preparation of 7 is completed, the process proceeds to step S34.

In step S34, the image signal string for one line input in step S32 is output to the signal line 21f.

In step S35, a pulse is generated on the signal line 21a, that is, the count value of the line counter 15 is incremented by 1.

In step S36, it is determined whether the signal line 24a is at the signal level "1", that is, whether the document exists at the reading position. If there is a document, the process proceeds to step S31 to read the next line. When the original is finished and the signal line 24a is at level "0", the process proceeds to step S37.

Steps S37 to S39 are steps for checking the width of the document set on the document table by adjusting the output of the document width detection circuit 12. In steps S37 to S39, the signal lines 12a, 12b, 1
It is determined whether 2c is at level "1".

When the signal line 12a is at level "1", that is, when the document width is the short side of A5, step S4 of FIG.
Move to 0. When the signal line 12b is at level "1", that is, when the document width is the length of the short side of A4, the process proceeds to step S51. When the signal line 12c is at level "1", that is, when the document width is the length of the short side of B4, the process proceeds to step S62 in FIG. When the signal line 12d is at level "1" (when all the signal lines 12a to 12c are at level "0"), that is, when the document width is the length of the short side of A3, the process proceeds to step S73 in FIG. move on.

Steps S40 to S50 in FIG.
Is a routine for checking the length of the document in the sub-scanning direction when the document width is A5 short side by adjusting the count value of the line counter 15 of the signal line 15a. Here, the sub-scanning line density is considered to be 3.85 lines / mm.

In step S40, the signal line 15a is set to 5
If it is 70 or less, that is, if the length of the document in the sub-scanning direction is 148 mm or less in view of the sub-scanning line density, the process proceeds to step S45 and the control device 21 sets its own register B.
“Or” may be stored in the memory (or may be a memory), and the process proceeds to step S84 in FIG.

Similarly, in step S41, the signal line 15
When a is 809 or less, that is, when the length of the document in the sub-scanning direction is 210 mm or less, "12" is stored in the B register (step S46), and the process proceeds to step S84.

In step S42, the signal line 15a is set to 9
If it is 89 or less, that is, if the length of the document is 257 mm or less, "13" is stored in the B register in step S47, and the process proceeds to step S84.

Further, in step S43, the signal line 15a is set to 1
If it is 143 or less, that is, if the length of the document is 297 mm or less, "14" is stored in the B register in step S48,
It proceeds to step S84.

Further, in step S44, the signal line 15a is set to 1
If it is 617 or less, that is, if the length of the document is 420 mm or less, "15" is stored in the B register in step S47,
It proceeds to step S84.

If all the above steps are denied, that is, the signal on the signal line 15a exceeds 1617,
If the length of the document exceeds 420 mm, "16" is stored in the B register and then the process proceeds to step S84.

Steps S51 to S on the lower side of FIG.
When the width of the document set on the document table is the length of the short side of A4, reference numeral 61 checks the length of the document in the sub-scanning direction in the same manner as in steps S40 to S50 described above, and according to the result, B The value of "21" to "26" is stored in the register.

That is, steps S51 to S5
Step 5 is to make the same determination as in steps S40 to S44.

If the signal line 15a is 570 or less in step S51, that is, the length of the document is 148 mm or less, "21" is stored in the B register in step S56, and the process proceeds to step S84.

If the signal line 15a is 809 or less, that is, the length of the document is 210 mm or less in step S52, "22" is stored in the B register in step S57, and the process proceeds to step S84.

If the signal line 15a is 989 or less in step S53, that is, the length of the document is 257 mm or less, "23" is stored in the B register in step S58, and the process proceeds to step S84.

In step S54, the signal line 15a becomes 1143.
Below, that is, when the length of the document is 297 mm or less, "24" is stored in the B register in step S59, and the process proceeds to step S84.

In step S55, the signal line 15a is set to 1617.
Below, that is, when the length of the document is 420 mm or less, "25" is stored in the B register in step S60, and the process proceeds to step S84.

If all steps S51 to S55 are denied, that is, if the length of the document exceeds 420 mm, "26" is stored in the B register in step S61, and the process proceeds to step S84.

In steps S62 to S72 on the upper side of FIG. 10, similarly to the above, when the document width is the short side of B4, "31" to "36" are stored in the B register according to the length of the document. The processing in each step is almost the same.

In step S62, the document length is 148 mm.
In the following cases, "31" is set in the B register in step S67.
Is stored. In step S63, the original length is 210m.
If m or less, in step S68, the B register is set to "3".

If it is less than 7 mm, "33" is stored in the B register in step S69. If the length of the document is 297 mm or less in step S65, "34" is stored in the B register in step S70, and if the length of the document is 420 mm or less in step S66, "35" is stored in the B register in step S71. Is stored. If step S66 is denied, "36" is stored in the B register in step S72. When each process is completed, the process proceeds to step S84.

In steps S73 to S83 on the lower side of FIG. 10, similarly to the above, when the document width is the short side of A3, "41" to "46" are stored in the B register according to the length of the document. The processing in each step is almost the same.

In step S73, the document length is 148 mm.
In the following cases, "41" is set in the B register in step S78.

If it is 7 mm or less, "43" is stored in the B register in step S80. If the original length is 297 mm or less in step S76, "44" is stored in the B register in step S81. If the original length is 420 mm or less in step S77, the B register is "45" in step S82. Is stored. If step S77 is denied, "46" is stored in the B register in step S83. When the above process ends, the process moves to step S84.

In step S84 of FIG. 11, the communication operation starts.

In step S84, it is determined whether or not a pulse is generated on the signal line 13c, that is, whether or not a DIS signal from the receiving side device is detected. When a pulse is generated on the signal line 13c, that is, when a DIS signal is detected, the process proceeds to step S85.

In step S85, the signal level of the signal line 13a is "1", that is, the maximum recording paper width on the receiving side is B.
It is determined whether the size is 4 or not. When the signal level of the signal line 13a is "1", that is, when the maximum recording paper width of the facsimile apparatus on the other side is B4 size, step S102.
Proceed to. If the signal level of the signal line 13a is "0", that is, the maximum recording paper width on the receiving side is not B4 size, the process proceeds to step S86.

In step S86, it is determined whether the level of the signal line 13b is "1", that is, the maximum recording paper width on the receiving side is A3 size. When this step is affirmed, the process proceeds to step S119. On the other hand, the signal line 13
If the level of b is "0", that is, if the maximum width of the recording paper of the receiving side facsimile device is A4 size, step S8.
Proceed to 7.

In steps S87 to S101, when the maximum recording paper width of the receiving side facsimile apparatus is A4 size, it is determined from which direction the data stored in the memory 17 is to be sent out, and a DCS signal is sent out. Is.

That is, from step S87 to step S
At 90, the contents of the B register are examined.

In step S87, the content of the B register is "2".
If it is any of 1 ”to“ 26 ”, and in step S88, the contents of the B register are“ 11 ”,“ 13 ”,
If the values are "14", "15" and "16", the flow shifts to step S96 to output the level "0" to the signal line 21g and read the contents of the memory 17 in the Q direction of FIG. That is, the image information is not rotated.

Subsequently, in steps S92 and S93, "0" is output to the signal lines 21d and 21e, respectively, and a DCS signal including information that the main scanning line length is A4 is transmitted. The DCS signal is transmitted in step S94 by the signal line 21.
This is done by generating a pulse on c. Then, in step S95, transmission is performed at the same size without rotation.

On the other hand, in steps S89 to S90, when the value of the B register is any of "33" to "36" or "43" to "46",
In step S97, the signal line 21g is set to level "0".
Is output. Therefore, similar to the above, no rotation is performed.

Then, in steps S98 and S99, the signal line 2
The level "0" is output to 1e, the information that the document size is A4 is added to the DCS signal, and then step S1 is performed.
At 00, a pulse is generated on the signal line 21c and a DCS signal is transmitted. Then, in step S101, reduction transmission is performed.

When steps S87 to S90 are denied, that is, the value of the B register is "12" or "3".
In the case of 1 ”,“ 32 ”or“ 42 ”, step S9
At "1", the level "1" is output to the signal line 21g so that the image information is read out by approximately 90 degrees.

Then, the process proceeds to step S92, and the same control as described above is performed thereafter. That is, the same size transmission rotated by approximately 90 degrees is performed in step S95. For example, A5
The original document is rotated by about 90 degrees and transmitted as shown in FIG.

Step S102 and subsequent steps in FIG. 12 are for the case where the recording paper width on the receiving side is B4 size.

In steps S102 to S105, the contents of the B register are determined as described above.

In steps S102 to S104, the contents of the B register are "31" to "36", "11", and "14".
If any of "16", "21", "22", and "24" to "26", the process proceeds to step S113.
Further, in step S105, the content of the B register is "44".
~ If it is any of "46", step S114
Move to. In addition, the above steps S102 to S105.
When all are denied, it transfers to step S106.

In step S106, a signal of level "1" is output to the signal line 21g, that is, control is performed so that the image information of the original is rotated by approximately 90 degrees with respect to the set direction.

Next, in steps S107 and S108, the level "0" is output to the signal lines 21e and 21d, and the FIF of the DCS signal is loaded with information indicating that the original size is A4.

Subsequently, in step S109, the contents of the B register are "31" to "34", "13", "23", "4".
3 ”is determined. If this step is denied, the process jumps to step S111.

In step S110, the level "1" is output to the signal line 21d, and the information that the document size is B4 is added to the DCS signal.

In step S111, a pulse is generated on the signal line 21c and a DCS signal is transmitted.

Subsequently, in step S112, equal-magnification transmission is performed. Here, in the case of passing through the above step S106, equal-magnification transmission rotated by approximately 90 degrees is performed. On the other hand, if the level "0" is output to the signal line 21g through step S113, the same-magnification transmission without rotation is performed.

In step S114, the signal line 21g
A signal of level "0" is output to. That is, no rotation is performed.

In steps S115 and S116, the levels "1" and "0" are output to the signal line 21e and the signal line 21d, respectively, and the information indicating that the document size is B4 is added to the FIF of the DCS signal.

In step S117, a pulse is generated on the signal line 21c to send out a DCS signal, and subsequently in step S118, reduction transmission is performed. Here, the image information of the original document is transmitted in the set orientation without being rotated.

After step S119 in FIG. 13, the processing is executed in step S86 in FIG. 11 when the recording paper width on the other side is A3.

In steps S119 to S122, the value of the B register is adjusted as described above.

When the content of the B register is any of "41" to "46" in step S119, the process proceeds to step S130.

Steps S120 and S121
The contents of the B register are "11", "15", "16",
Alternatively, if any of "21", "22", "25", and "26", the process proceeds to step S133.

If the content of the B register is any of "31" to "33", "35", and "36" in step S122, the process proceeds to step S136.

When all the steps S119 to S122 are denied, the process moves to step S123.

In step S123, the signal line 21g
The signal level "1" is output to the memory 17, that is, the image information of the original is rotated by about 90 degrees with respect to the set direction,
Read from.

In steps S124 and S125, the signal line 2
The level "0" is output to 1d and 21e, and the fact that this original is A4 size is added to the FIF of the DCS signal.

In step S126, it is determined whether the contents of the B register are "13" to "23". When this step is affirmed, the process proceeds to step S139, the level "1" is output to the signal line 21d, the information on the FIF document of the DCS signal is rewritten to indicate the B4 document, and the process proceeds to step S128.

When step S126 is denied, the routine proceeds to step S127, where the content of the B register is "1".
It is determined whether it is any of "4", "24", and "34". If this step is denied, the process proceeds to step S128, and if affirmed, step S1
At 40, the level "1" is output to the signal line 21e, the document size information of the FIF of the DCS signal is rewritten to indicate the A3 document, and the process proceeds to step S128.

At steps S130, S133 and S136, the level "0" is output to the signal line 21g. This allows transmission without rotation.

In steps S131 and S132, the levels "0" and "1" are output to the signal lines 21d and 21e, respectively, and the information indicating the A3 size is written in the document size area of the FIF of the DCS signal, and then in step S128. Transition.

In steps S134 and S135, the levels "0" and "0" are output to the signal lines 21d and 21e, respectively, and the information indicating the A4 size is written in the document size area of the FIF of the DCS signal, and then in step S128. Transition.

In steps S137 and S138, the levels "1" and "0" are output to the signal lines 21d and 21e, respectively, and after the information indicating the B4 size is written in the document size area of the FIF of the DCS signal, the process proceeds to step S128. Transition.

In step S128, a pulse is generated on the signal line 21c, and the DCS signal in which the information about the document size is written is transmitted as described above.

Subsequently, in step S129, equal-magnification transmission is performed. Almost 90 when passing through step S123
The rotated image information is transmitted at the same size, and step S13 is performed.
When 0, S133, and S136 are passed, equal-magnification 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 to perform equal-size or reduced transmission, waste of recording paper can be prevented, and transmission time can be shortened. . Image information is stored in memory in advance, so
When the rotation is performed, the transmission time of the image information in the sub-scanning direction can be shortened as compared with the case where the transmission is performed as it is, so that the transmission time can be shortened. For example, when the recording paper is A4 wide and the original is A5 in the vertical position, the image information is rotated by about 90 degrees, and is recorded in the horizontal position on the receiving side. When the recording paper width is A4 and the document is A4 in the horizontal position, the image information is rotated and the image information is recorded in the vertical position on the receiving side. When the document is B4 in the horizontal position, the image information is further reduced.

In the above embodiment, the image information is rotated by changing the memory reading direction of the image information, but the original may 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, DIS, D conforming to CCITT (International Telegraph and Telephone Consultative Committee) Recommendation T30
Although the CS signal is shown as an example, it is needless to say that the present invention can be similarly implemented in a facsimile machine in which the communication regarding the size of the original and the recording paper is performed using the signal of another format.
