Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for reducing an image at a transmission source and transmitting the image.
The present invention relates to a facsimile apparatus configured to keep a reduction ratio constant within the same document.

[0002]

2. Description of the Related Art Conventionally, as a protocol for performing facsimile transmission, there is a G3 facsimile standardized for an analog telephone network which is a public line.

The G3 facsimile has been standardized by the International Telegraph and Telephone Consultative Committee (ITU-T).
4 width, B4 width, or A3 width
This is a technology that can transmit images. Therefore, which document width is used to transmit an image is selected based on the actual document width transmitted from the transmitting side.

[0004] However, in a facsimile apparatus as an individual terminal, images to be handled may be limited. This is because the width of a document (recording width capability) that can be recorded by the facsimile apparatus is limited.

Accordingly, if the recording width capability of the transmitting facsimile device corresponds to the A3 width and the recording width capability of the receiving facsimile device also corresponds to the A3 width, the A4 width can be set between the two facsimile devices. It is possible to transmit and receive any of the originals of width, B4 width, and A3 width.

[0006]

However, despite the fact that the recording width capability of the transmitting facsimile device is A3 width, the recording width capability of the receiving facsimile device is B4.
If the width is a width, the document width that can be transmitted and received between the two facsimile apparatuses is limited to a B4 width document or a A4 width document that is a document width equal to or less than the B4 width.
I cannot send and receive 3-width originals.

Further, if the recording width capability of the facsimile machine on the receiving side is A4 width, even if the recording width capability of the facsimile device on the transmitting side is A3, the document width that can be transmitted and received by both sides is A4 width. A3 width and B
4 width documents cannot be sent or received.

Here, the recording width capability of the facsimile apparatus is generally determined by the size of the original to be used as the recording paper. For example, a facsimile apparatus included in a digital copying machine capable of setting a plurality of types of recording paper including a recording paper of A3 width as a paper tray has a recording width capability of A3, whereas a facsimile apparatus of B4 width or A4 width is used. In general, a personal facsimile apparatus in which only the recording paper can be set has a recording width capability of only B4 or A4.

Therefore, for example, even when a document of A3 width is transmitted, the recording width capability of the receiving facsimile apparatus is A4.
If so, it must be transmitted as an A4 width document. In this case, in order to prevent image loss on the receiving side, a method of reducing the size of an A3 width document to an A4 width image when reading or transmitting the document and transmitting the reduced image is used in the related art. .

As described above, normally, when the width of a document taken in by the facsimile apparatus on the transmitting side is larger than the recording width capability on the receiving side, the image on the transmitting side is reduced so as to be within the recording width capability on the receiving side.

In the case where the receiving facsimile apparatus is configured to store a plurality of paper trays as described above, the paper width of the original to be transmitted and received is set within the recording width capability of the receiving facsimile apparatus for each page. It is possible to change to That is, in one transmission, it is possible to mix and transmit originals having different sheet widths.

[0012] For example, when the recording capacity of the receiving facsimile apparatus is A3, even if the transmitting facsimile apparatus mixes and transmits originals of A3 width, B4 width, and A4 width, the facsimile apparatus of the receiving side transmits the original document. Since the image of each page can be received at an appropriate width in the apparatus, if all the sheets of A3 width, B4 width, and A4 width are set in the facsimile apparatus on the receiving side, each page can be appropriately received. It is possible to output on paper of the size (the same size as the original size on the transmission side).

However, for example, if the facsimile apparatus on the transmitting side has a recording width capability of B4, the transmitting side has an A3 width,
When a document of B4 width and A4 width is mixed and transmitted,
As described above, in the facsimile machine on the receiving side, A
Since an image having a width of 3 can be received only as an image having a width of B4 at the maximum, an image having an width of A3 is transmitted as an image having a width of B4.

On the other hand, since images of A4 width and B4 width can be received as images of A4 width or B4 width, they are transmitted at the same size without being reduced.

Therefore, in the above case, only the document having the A3 width on the transmitting side is reduced, and the image of the other document width is received at the same size. The reduction rate is received differently.
This is due to the fact that the font size changes from page to page in the text document, making it difficult to read, as well as the fact that the scale (reduction rate) is not unified for each page in drawings and the like. It is a factor of the inconvenience that occurs.

As an example of a method for solving such a problem, a difference between an original having a size smaller than A3 width, that is, an original having B4 width and an A4 width is read as a margin, and all the originals are read. A method of using the original of page A as an original of A3 width is conceivable. As a result, the originals output on the receiving side can all be the same originals without depending on the size of the original original on the transmitting side.

However, as described above, when the width of all the originals is set to be A3 width, even if the originals of A3 width are not mixed, the A3 size of the original based on all the images is reduced. Since a margin of the difference is added, it becomes impossible for the receiving-side facsimile apparatus to output an appropriate size.

Accordingly, the present invention has been made in view of the above problems, and detects the maximum width of a transmission image before transmission and compares it with the recording width capability of the receiver.
Know in advance whether it is necessary to reduce the size of the document and send it. If this is necessary, send all pages according to the maximum document width to unify the reduction ratio for all pages. It is an object of the present invention to provide a facsimile apparatus in which a document is transmitted according to the document width of each page to output the document at an appropriate size on the receiving side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a facsimile apparatus according to the present invention will be described in detail with reference to the drawings. First, the standard protocol procedure of the G3 facsimile will be briefly described. The G3 facsimile communication procedure is roughly divided into the following five phases.

[G3 facsimile communication procedure] That is, first, as a phase A, a call is made from the transmission source facsimile apparatus to the transmission destination facsimile apparatus, and then, as a phase B, before the image data is actually transmitted. Procedure (where the transmitting and receiving capabilities are identified to determine the transmission conditions), and then, as phase C, transmission of image data from the facsimile apparatus on the transmitting side, and then phase D
As a procedure after completion of image data transmission (here, an instruction after image data transmission and reception confirmation are performed),
Finally, as phase E, there is a communication procedure such as disconnection of a line established between the facsimile machine on the transmitting side and the facsimile machine on the receiving side.

A specific example of the standard G3 protocol communication as described above will be described in detail with reference to the sequence shown in FIG.

Referring to FIG. 1, first, a calling signal CNG of 1100 Hz is transmitted from the calling side to the called side (A _S 1).
→ A _R 1). At this time, when the called terminal receives the CNG, the called terminal transmits a 2100 Hz called terminal identification signal CE to the calling terminal.
D is transmitted ( _AR2 → _AS2 ). This is the phase A.

Next, the calling terminal and the called terminal shift to phase B. In this phase B, first, the called side transmits the CED in the phase A, followed by the called terminal identification signal CSI and the digital identification signal DIS (B _R 2
→ B _S 1, B _R 3 → B _S 2). CSI in the above is a signal for transmitting the CSI code (international identification number) of the called terminal to the calling side, and DIS is a function (recording capacity and resolution supported by the receiving side) of the receiving side. Signal for transmitting the capacity, compression method, etc.).

[0039] After receiving the DIS in contrast calling, first sends a transmission terminal identification signal TSI to the called and then transmits a digital command signal DCS to the called (B _S 3 → B
_{R 4, B S 4 → B} R 5). The TSI in the above is a signal for transmitting the CSI code of the calling side to the called side.
CS is a signal for transmitting communication conditions (such as image width, resolution, compression method, etc.) determined from the function of the calling side and the terminal functions of the called side identified by DIS.

Next, in order to determine the communication speed between the terminal on the calling side and the terminal on the called side, a training signal TCF is transmitted from the calling side to the called side (B _S 6 → B _R 6). Normally, this TCF is transmitted at the communication speed which is the highest speed between the calling side and the called side in the initial stage.

Next, when properly received the signal at the called party, the called station sends a reception preparation confirmation signal CFR to the caller _{(B R 7 → B S 7} ). Further, in the called side, when the above TCF is not normally received, the called station sends a training failure signal FTT to the calling side _{(B R 7 → B S 7} ). On the calling side, at B _S 8, F
When I received the TT, moves to B _S 5, again sending the TCF drop the speed _{(B S 6 → B R 6} ). Here, for example, at a communication speed of 28800 bps from the calling side, T
When has been returned FTT than the called side to the case of transmitting CS, then the calling side transmits a TCF to the called party at a communication speed of _{26400bps (B S 6 → B R} 6).
When the calling side receives a CRF from the called side indicating that the TCF has been successfully received, the communication speed at the time of transmitting the TCF corresponding to the CRF is stored. Thus, the phase B ends.

Next, the process proceeds to phase C. Here, the scanned image is transmitted as a message from the calling side to the called side at the speed determined by the TCF in phase B ( _CS).
1 → _CR 2).

In the phase C, the image transmission for one page is performed. Therefore, when the image transmission for one page is completed, the process proceeds to the phase D. In phase D, if there is no next page, the procedure end signal EOP is sent from the calling side to the called side.
There is transmitted _{(D S 1 → D R 1} ). Further, there is the next page, when transmitting a message (image) of the next page is and the same transmission mode from the calling station, the multi-page signal MPS is transmitted from the calling side to the called side (D _S 1 → D
_R 1). When there is a next page and a message (image) of the next page is transmitted in a different transmission mode from the calling side, a message end signal EO is sent from the calling side to the called side.
M is sent _{(D S 1 → D R 1} ). On the other hand, when the called side receives any of EOP, MPS, or EOM, it transmits a message confirmation signal MCF to the calling side (D _R 2 → D _S 2).

Thereafter, when the calling side receives the MCF, the
Term D ends. After this, any of the above mentioned features
Phase EOP, MPS, EOM
Which is transmitted. That is, D_S1
→ D_RCaller sent EOP in communication 1
If there is no next page, proceed to phase E
No. In this phase E, a disconnection command signal is sent from the calling side to the called side.
No. DCN is transmitted (E _S1 → E_R1), disconnect the line
Communication ends.

When the MPS is transmitted from the calling side in the communication of D _S 1 → D _R 1, that is, when the next page is transmitted in the same transmission mode, C _R 1 in phase C at the time of D _R 3. Then, the process proceeds to transmission of a message (image) on the next page.

[0046] When the EOM from the caller is transmitted in the communication of D _S 1 → D _R 1, that is, when transmitting the next page in a different transmission mode, is transmitted and received in the communication of B _S 4 → B _R 5 Since it is necessary to re-determine the transmission condition once determined by the DCS, the process returns to B _R 1 in phase B at D _R 4.

Here, in the G3 standard protocol, communication is not permitted from the middle of a phase, and skipping communication in the middle of a phase is not permitted. Therefore, no matter how the transmission mode changes, it is necessary to transmit the EOM and start over from the beginning of phase B.

There are two types of facsimile transmission, direct transmission and memory transmission. Direct transmission is a method in which an outgoing call is first made, the image of the original is read one page at a time after the line is established with the partner machine, and the image is transmitted on the spot every time one page is read. Further, the memory transmission is a method of reading an image of all pages of a document, storing the image in a memory, then making a call to establish a line with a partner device, and transmitting the image stored in the memory after the establishment in the order of reading. is there.

Regarding the two facsimile transmissions, the direct transmission starts reading the original after confirming that it is connected to the partner machine, so that the image data can be reliably transmitted as soon as the communication is established. On the contrary,
With memory transmission, the same image stored in memory can be sent to multiple destinations, and even if the other party is busy and connection is not possible, it is possible to redial and send There is an advantage that it is.

[Document Reading Configuration] Next, a procedure for continuously reading a plurality of documents using the automatic document feeder (ADF) 1 will be described in detail with reference to FIG.

Referring to FIG. 2, an automatic document feeder (A
DF) 1 feeds out a document from a document group 3 placed on a document table 2 by a feed roller 4, separates the topmost document by a separation roller 5 and a reverse roller 6, The document is rotated and fed until the leading edge of the document reaches the registration position 8 in front of the scanner 10.

A registration sensor 9 is provided in front of the registration position 8, and the feed roller 7 is stopped after a predetermined time has passed after the leading end of the document has passed the registration sensor 9, so that the leading end of the document is positioned at the registration position. 8 can be stopped.

Here, after the documents are separated one by one,
Before the leading edge of the document is fed to the registration position 8,
The width of the document can be detected one by one by the width sensor 11.

Next, the lamp of the scanner 10 is turned on to prepare for scanning the image of the passing document. After that, the paper feed roller 7 and the paper discharge roller 12 are rotated,
The document whose leading end is at the registration position 8 is conveyed and discharged to the discharge port 13. During this conveyance, the document from the leading edge to the trailing edge passes through the scanner 10. Therefore, by opening the gate of the scanner 10 during the passage, the document image is scanned from the leading edge to the trailing edge.

Regarding the timing for opening the gate of the scanner 10 at the leading edge of the document, the gate is opened a fixed time after the roller is moved (the distance from the registration position 8 to the scanner 10) and the gate is closed at the trailing edge of the document. For example, the gate may be closed a fixed time after the rear end of the document passes the registration sensor 9 (the distance from the registration sensor 9 to the scanner 10).

On the other hand, the image scanned by the scanner 10 is transferred to the facsimile control unit 21. The transferred image is first stored in the page memory 22. Thereafter, in the case of direct transmission, the image stored in the page memory 22 is compressed by the modem compressor 27 using the compression method determined by the phase B DCS and transferred to the modem 24. The modem 24 modulates the compressed image signal transferred from the page memory 22 and transmits it to the receiver as a message signal in phase C (C _S1 → C _R 1).

On the other hand, in the case of memory transmission, the image stored in the page memory 22 is transferred to the SAF 23 and stored. When the data is stored in the SAF 23, the data is compressed and stored by the compressor 25 in order to save the SAF capacity.

Thereafter, as described above, when the transmission or reading of one document is completed by either direct transmission or memory transmission, the automatic document feeder 1 determines whether there is a next document or not by the next document presence / absence sensor 14. When there is a next original, the same operation as described above is performed by repeating the same operation from the sheet feeding.

The presence / absence of the next document can be determined by checking the next document presence sensor 14 provided on the document table 2. When checking the next document presence sensor 14, it is necessary to check at the timing when the trailing edge of the previous document has advanced beyond the next document presence sensor 14. For example, at the timing of scanning end (timing to close the gate of the scanner). Just check it.

When the image stored in the SAF 23 is transmitted to the other device by memory transmission, the image compressed and stored in the SAF 23 is expanded in the page memory 22 by the expander 26 first. Then, the data is recompressed by the modem compressor 27 in accordance with the compression method determined by the phase B DCS (B _S 4 → B _R 5) and transferred to the modem 24 (here, SA).
If the compression method for storing data in F23 and the compression method for transferring data to modem 24 are the same, the data can be transferred from SAF 23 to modem 24 without decompression / recompression.
The modem 24 modulates the transferred image signal and transmits it to the receiver as a message signal in phase C (C _S 1 → C _R 1).

In the configuration described above, the present invention provides:
Before sending, the maximum width of the transmitted image is detected in advance, and it is compared with the recording width capability of the receiver to understand in advance whether it is necessary to reduce the size of the image and transmit it. The size of the document is adjusted according to the maximum document width, so that the reduction ratio is standardized for all pages. If it is not necessary (when all pages can be sent at the same size), the size of the document is sent according to the width of the document. It is an object of the present invention to provide a facsimile machine which outputs an image with an appropriate size. Therefore, the embodiment for describing the present invention has the following configuration.

[First Embodiment] First, referring to the drawings,
A first embodiment of the facsimile apparatus according to the present invention will be described in detail.

In the first embodiment, in the direct transmission mode, the reading of the original image is started after the receiver and the line are connected, and the read page is immediately transmitted when the reading is completed for each page. The maximum document width is detected in advance, and before reading the first page, the maximum document width is compared with the recording width capability of the receiver (maximum document width)>
In the case of (recording capacity width of the receiver), since reduced transmission occurs, all pages are read at a magnification corresponding to the reduction rate at the time of the maximum document width, and (maximum document width) ≦ (recording capacity width of the receiver) In the case of), all pages can be transmitted at the same size. If reduced transmission occurs in the direct transmission mode by reading all pages at their original widths, the reduction ratio is unified for all pages, and so on. It is an object of the present invention to allow a receiving side to output a document of the same size as that of a transmitting side when a reduced transmission does not occur, while maintaining the multiplicity.

Accordingly, the facsimile apparatus according to the first embodiment includes the automatic document feeder 1 and the facsimile controller 21 shown in FIG.

(Maximum Document Width Detection Mechanism) In describing the first embodiment, FIG. 3 shows a specific example of a configuration for detecting the "maximum document width". FIG. 3 is a top view of the document table 2 of the ADF 1 as viewed from above.

Referring to FIG. 3, the originals of A4, B4 and A3 are all set so that the leading end and the right end are aligned with the upper left reference position 31. This is because if the right edge of the document is just aligned, the left side of the document is not fixed, so that there is a disadvantage that the document is likely to bend and be conveyed during paper feeding,
The guide plate 32 is set so that the guide plate 32 contacts the left end of the document.
Is adjusted. Here, the guide plate 32 can be moved perpendicularly to the paper feeding direction, and the position can be adjusted according to the width of the document.

Here, as shown in FIG. 3, when originals having different widths are mixed and transmitted, the guide plate 32 is adjusted in accordance with the original having the largest width. Therefore, by detecting the position of the guide plate 32, the "maximum document width" for the document group set on the document table can be detected. If there is no such a mechanism for detecting the "maximum document width", the user can designate the "maximum document width" in advance and use it instead.

(Operation of First Embodiment) Next, referring to FIG. 4, FIG. 2 having a function of detecting the "maximum document width" by the maximum document width detecting mechanism shown in FIG. 3 according to the first embodiment.
1 shows a flow of direct transmission by a facsimile apparatus according to the present invention (hereinafter, referred to as a facsimile apparatus 100) when the ADF is used. In the facsimile apparatus shown in FIG.
It is assumed that the image at the time of transmission is reduced by changing the magnification at the time of scanning.

Referring to FIG. 4, when a destination is input (step S101), the facsimile apparatus according to the present invention dials the telephone number of the destination machine (step S1).
02). As a result, when communication with the partner machine is established, the facsimile apparatus 100 transmits CNG to the partner machine, and thereafter waits until CED is received (step S103). This step is phase A.

After the step S103, the facsimile apparatus 100 detects the "maximum document width" (A3 width / B4 width / A4 width) for the document group on the platen by the method described above (step S104). ).

Next, the facsimile machine 100 moves the first original to the registration position 8 in the automatic original feeder 1.
And the width of the original (A3 width / B4 width / A4 width)
Is detected (step S105).

Next, the facsimile machine 100 receives CSI / DIS from the partner machine as phase B communication (step S106). Here, the recording width capability (A3 width / B4 width / A4 width) of the partner machine can be recognized from the DIS.

Thereafter, the facsimile apparatus 100
I is transmitted (step S107). Here, as shown in FIG. 2, before transmitting the DCS, the “maximum document width” detected in advance and the recording width capability of the partner machine are set to (A3 width> B
4 width> A4 width) (step S1).
08) Based on the result, “reading width” and “reading magnification” set at the time of scanning, and “image width” when transmitting a message (image) to the other party in phase C of notifying the other party by DCS transmission Is determined. (Where "reading width" x "reading magnification" = "image width"
There is a relationship. )

As a result of the comparison in step S108,
When the “maximum document width” exceeds the recording width capability of the partner machine (maximum document width = A3 width / B4 width and the recording capability width of the partner machine =
A4 width or maximum document width = A3 width and recording capacity width of the other machine =
In the case of B4 width: Yes in step S108, the facsimile apparatus 100 determines that it is necessary to reduce the size and transmit the reduced size. At this time, in order to transmit the images of all the originals at the same magnification, the case where the image of the “maximum original width” is transmitted is reduced most. Therefore, it is necessary to scan all the originals at the magnification at this time.

For this reason, the facsimile apparatus 100
The “reading magnification” is set to a value obtained by dividing the “recording capacity of the partner device” by the “maximum document width” (step S109). This is because, for example, the “recording width capability of the partner machine” is B4 width (257
mm)), assuming that the “maximum document width” is the A3 width (297 mm), the “reading magnification” is 257 ÷ 297 = 0.865
Becomes Also, by setting the “reading width” to A3 width and the “image width” to B4 width, this reading magnification can be obtained. Therefore, regardless of the document width of the page, the “reading width” is set to A3 width (maximum). Original width), “Image width” is B4
Set to the width (recording capacity of the partner machine).

On the other hand, as a result of the comparison in step S108, if the "maximum document width" does not exceed the recording width capability of the partner machine (No in step S108), the facsimile apparatus 100 can send all pages at the same size. Judge. In this case, the “reading magnification” is set to the same size (= 1) (step S111). Naturally, if the setting is made such that “reading width” = “image width”, the “reading magnification” becomes the same size. In this case, the original width of each page is set to “reading width” and “image width”. It suffices that the receiving side can output to an appropriate sheet.

After determining the reading magnification as in step S109 or step S111 described above, the facsimile apparatus 100 transmits DCS next (step S109).
110 or step S112). In this DCS transmission, the "image width" determined as described above is notified to the other party. For example, when “reading magnification” is set to a value obtained by dividing “the recording width capability of the partner machine” by “maximum document width” in step S109, “image width” = “recording width capability” in step S110. DCS is transmitted, and in step S111, “read width” =
If the setting is made to be "image width", step S11
In step 2, DCS is transmitted with “image width” = “document width”.

After transmitting the “image width” to the partner machine in this way,
The facsimile machine 100 performs training (T
Perform CF transmission and CFR / FTT reception (Step S1)
13).

Next, the "reading width" and the "reading magnification" determined in step S109 or step S111.
Are set in the scanner 10 (step S114), the document at the registration position 8 is scanned, and transmitted as a message (step S115). The process up to this is phase C.

Here, the "reading magnification" of the scanner 10
The setting may be made as follows.

That is, the resolution at the time of the same magnification is 200 dp in the main scanning.
i, sub-scanning 200 dpi, when the “reading magnification” is the same magnification, the main scanning 200 dpi and the sub-scanning 200 dpi
Set with i. The “scan magnification” is 0.865
In the case of (A3 width → B4 width), main scanning 200 × 0.86
5 = 173 dpi, sub-scanning 200 × 0.865 = 173
Set in dpi. When an image scanned at such a resolution is printed at 200 dpi in the main scan and 200 dpi in the sub-scan, the image is reduced to 0.865 times the original image.

When the scan is completed through these steps, the presence / absence of the next original can be detected. At the end of the scan, the presence / absence of the next original is checked (determined) (step S).
116).

If the result of the next document presence / absence determination in step S116 is "no next document" (step S11)
No. 6), the facsimile apparatus 100 proceeds to step S1
The EOP is transmitted to the partner device following the message transmitted in step 15 (step S124), and then the process waits until the MCF transmitted from the partner device is received (step S12).
5). This stage is phase D.

In step S125, the MC
Upon receiving F, the facsimile machine 100 transmits a DCN to the partner machine (step S126), disconnects the line, and ends the communication. This stage is phase E.

In the above step S116,
In the case of "there is next document" (Yes in step S116)
Feeds the next document (at this time, the width of the document is detected: step S117).

Thereafter, it is determined whether or not the “maximum document width” detected in step S117 exceeds the “recording width capability of the partner machine” (step S118).

In step S118, if the "maximum document width" does not exceed the "recording capacity of the partner machine" (No in step S118), it is determined whether the width of the next document has changed from the previous document. Is determined (step S119),
If it has changed (Yes in step S119), the facsimile machine 100 transmits the EOM to the partner machine (step S122), and then waits until receiving the MCF transmitted from the partner machine (step S123: (Phase E), and then return to step S106 (Phase B) to receive CSI from the partner device.

If the width of the next original document does not change in step S119 (No in step S119), facsimile apparatus 100 transmits MPS to the other machine (step S120: phase D), and then the other machine transmits the MPS. Wait until the MCF to be transmitted is received (step S
121: phase D), and then the “read width” of the scanner in step S114 (before phase C)
And return to the “reading magnification” setting.

However, from step S121 to step S1
It is assumed that the values of “reading width” and “reading magnification” set in scan 10 when returning to 14 are the same values as the previous time. (For simplicity, it is assumed here that transmission conditions other than "document width" do not change.)

If it is determined in step S118 that the "maximum document width" exceeds the "recording width capability of the other machine" (Yes in step S118), the "image width" is changed regardless of the document width as described above. The “image width” does not change because the “image width” is transmitted as “the recording width capability of the other device”. Therefore, the process proceeds to step S120, where the MPS is transmitted to the partner device,
Next, in step S121, the process waits until an MCF transmitted from the partner device is received.
The process returns to the setting of “reading width” and “reading magnification” of the scanner in 4 (before phase C).

Here, as can be seen from the flow shown in FIG. 4, when the “maximum document width” on the transmitting side exceeds the “recording capacity width of the partner machine”, the “reading magnification” is first set, and then the “reading magnification” is set. After the first sheet, the image is read and transmitted at the same magnification without changing the scanner setting and the transmission image width. Therefore, transmission can be performed at the same reduction rate throughout all pages.

On the other hand, if the “maximum document width” does not exceed the “recording capacity width of the partner machine”, the “reading magnification” is always the same size, and “image width = document width” is always transmitted. Understand (During the protocol, when returning to phase B, D
Since the IS is received, the recording width capability of the partner device may change on the way, but it is assumed that the recording width capability of the partner device does not change in one communication.) For this reason, when the transmission is always performed at the same magnification, the transmission is performed in accordance with the width of each page, so that the receiving side can output to an appropriate sheet.

[Second Embodiment] Next, referring to the drawings,
A second embodiment of the facsimile apparatus according to the present invention will be described in detail.

In the second embodiment, in a memory transmission mode in which images of all pages of a document are read and temporarily stored in a memory, and then the images stored in the memory are transmitted, an image stored beforehand is transmitted before transmission. The maximum width is detected, and before the transmission of the first page, the maximum image width is compared with the recording width capability of the receiver, and (maximum image width)> (recording capability width of the receiver)
In the case of, reduced transmission occurs, so add a margin to the image of the page that is less than the maximum image width at the time of transmission, calibrate the image width to match the maximum image width, and reduce all pages at the same magnification. In the case of (maximum image width) ≦ (recording width of receiver), all pages can be transmitted at the same size, so that the data is transmitted as it is. Unify the rate for all pages to maintain equal magnification between each page, and if reduced transmission does not occur, enable the receiving side to output documents of the same size as the sending side on documents with mixed sizes. It is an object.

(Operation of the Second Embodiment) Next, referring to FIG. 5, a flow of an operation (memory storage) of storing an original image in the SAF 23 using the ADF 1 of FIG. 2 according to the first embodiment will be described. This will be described in detail. Also, referring to FIG.
The flow of the operation (memory transmission) for transmitting the image stored in the storage device 23 will be described in detail.

(Operation of Memory Storage) Referring to FIG.
In the memory transmission, the originals stacked on the ADF 1 are sequentially scanned, and the image thus captured is sent to the SAF 2
3 includes an operation of setting a “maximum document width” required for memory transmission.

As for this operation, referring to FIG. 5, first, when a user inputs a destination to the facsimile machine 100 (step S201), the facsimile machine 100
Sets the "maximum document width" to the A4 width (minimum width) (step S202).

Next, the facsimile machine 100
1 feeds the first document stacked on the document table 2 to the registration position 8, and the width of the document (A4 width / B4 width /
A3 width) is detected (step S203).

Next, the document width detected in step S203 is compared with the value of the "maximum document width" set at this time (step S204), and step S204 is performed.
If the detected document width is larger than the "maximum document width" set at that time (Yes in step S204), the "maximum document width" is set to the width of the document and the "maximum document width" is set. Is updated (step S20).
5) If the detected document width is equal to or smaller than the "maximum document width" set at that time as a result of the comparison in step S204 (No in step S204), the process proceeds to step S206.

Thereafter, as the settings of the scanner 10, for example, the "reading width" is set to the width of the original and the "reading magnification" is set to the same magnification (step S206). The image of the page is stored in the SAF 23 (step S207). Here, when reading out from the SAF 23, the document width of the page can be quoted.

After performing the operation on the one-page document in this way, it is determined whether or not there is a next document (step S2).
08) If there is a next original (Ye in step S208)
s), repeating from the document feeding in step S203, and if there is no next document (No in step S208),
The accumulation in the AF 23 ends. At the end of the process, the “maximum document width” is set to the maximum width of the stored images.

(Image Transmission Operation) Next, referring to FIG. 6, when an image is stored in the SAF 23 by the operation shown in FIG. 5, the facsimile apparatus 100 proceeds to step S2 in FIG.
In step S301, the user dials the destination input when the memory is stored in step 01, and establishes a line with the partner device.

Thereafter, facsimile apparatus 100 transmits CNG to the other party, and thereafter waits until receiving the CED transmitted from the other party (step S30).
2: Phase A).

Thereafter, the facsimile machine 100
The image of the first page of the document stored in F23 is read out together with the width of the image (document width) (step S30).
3). At this time, the “maximum document width” set at the time of memory storage in step S207 shown in FIG. 5 is also read.

Next, the facsimile apparatus 100 receives CSI / DIS from the partner machine as phase B communication (step S304). Here, the facsimile machine 10
0 indicates the recording width capability (A3 width / B4 width / A4 width) of the partner machine from the DIS.

Next, facsimile apparatus 100 transmits the TSI to the partner machine (step S305), and then transmits the DCS. Here, in order to determine the "image width" to be transmitted by the DCS, " The "maximum original width" is compared with the "recording width capability of the partner machine" (step S306).

As a result of the comparison in step S306, when the “maximum document width” exceeds the “recording width capability of the partner machine” (when it is necessary to reduce the transmission: step S306)
Yes), the process proceeds to step S307 to transmit the “recording width capability of the other device”, and if the “maximum document width” is equal to or less than the “recording capability of the other device” (when all pages can be sent at the same size): (No in step S306), the original width of the page is transmitted as it is (step S308).

Thereafter, the facsimile apparatus 100 performs training (TCF transmission, CFR / FTT reception) with the partner machine.
Is performed (step S309).

Next, before entering the phase C, the facsimile apparatus 100 compares the “maximum original width” with the “recording width capability of the partner machine” (step S310), and determines the “maximum original width”.
Exceeds the “recording capacity of the other device” (step S3
(Yes in 10), in performing the process of reducing the page read from the SAF 23, the “document width” and the “maximum document width” of the target page are compared (step S31).
1) If the “document width” is less than the “maximum document width” as a result of the comparison in step S311 (Y in step S311)
es) A margin is added in the main scanning direction (width direction) so that the image to be transmitted has the maximum image width (step S31).
2). This means that the maximum document width is A3 (297 mm)
If the page width is A4 (210 mm), 29
By adding a margin of 7-210 = 87 [mm] in the main scanning direction, an image having an A4 width is made to have an A3 width. This operation will be described in detail below as a third embodiment.

As a result of the comparison in step S311,
If the “document width” is equal to or larger than the “maximum document width” (No in step S311), the process directly proceeds to step S313.

Next, after the image width is matched with the maximum original width as described above, the image is further reduced to the width of the “recording width capability of the partner machine” (step S313). In this case, the line is reduced from the "maximum document width" to the "recording width capability of the other device" by thinning out the lines in both the main scanning and the sub-scanning at the ratio of "recording capability of the other device" / "maximum document width". . This is, for example, from A3 (297 mm width) to B4 (257 mm width).
mm), 4 out of 297 lines in the main scanning direction
The 0 (= 297-257) line is thinned out as evenly as possible.

FIG. 7 is a drawing for explaining the operation in step S313. FIG. 7 shows an example of a method of evenly thinning out 40 lines out of 297 lines. Referring to FIG. 7, one line is sequentially assigned to each line with respect to the acquired image data.
297 40 × 1, 297 ま で 40 × 2,..., 2
Lines with 97 ÷ 40 × 39, 297 ÷ 40 × 40 numbers (rounded down to the decimal point) are thinned out. Sub-scanning lines are also thinned out at a similar rate.

As a result of the comparison in step S310,
If the "maximum document width" is equal to or smaller than the "recording width capability of the partner machine" (No in step S310), the process proceeds to step S3.
Go to 14.

In step S314, when the "maximum document width" exceeds the "recording width capability of the partner machine" (step S31).
0), from step S311 to step S3
In the case where the margins have been added and thinned out by the operations up to 13, and the “maximum document width” is equal to or smaller than the “recording width capability of the partner machine” (No in step S310), the SAF
Then, the image read out from 23 is transmitted as it is to the partner device as a message (step S314: phase C).

Next, the facsimile apparatus 100 operates in the SAF mode.
23 (step S315), and if the next page is not stored (No at step S315), the EOP is transmitted to the partner machine (step S325).
It waits until the MCF transmitted from the partner device is received (step S326: phase D), and after receiving, transmits a DCN to the partner device (step S327: phase E), disconnects the line, and ends the communication. .

If there is a next page in step S315 (Yes in step S315), facsimile machine 100 reads the next page from SAF 23 (step S316), and thereafter, "maximum document width" and "recording of partner machine" Width capability "(step S31).
7).

As a result of the comparison in step S317, when the "maximum document width" exceeds the "recording width capability of the partner machine" (Yes in step S317), the facsimile apparatus 100 does not change the image width at the time of transmission, so (Step S318). After that, the facsimile apparatus 100 receives the MCF transmitted from the partner machine (step S319: phase D), and returns to step S311 because whether or not a margin is added and the amount of addition vary according to the width of the next page. Then, it is determined whether to add a margin.

Also, as a result of the comparison in step S317,
If the “maximum image width” does not exceed the “recording width capability of the other device” (No in step S317), it is determined whether the document width of the next page has changed from the previous document width (step S320). If the result of determination in step S320 is that the width of the next page does not change (No in step S320),
The facsimile machine 100 transmits the MPS to the partner machine (step S321), and then waits until receiving the MCF transmitted from the partner machine (step S32).
2: Phase D). Then, the facsimile machine 100
Returns to the message transmission in step S314 (phase C).

When the width of the next page changes as a result of the determination in step S320 (Yes in step S320)
s), the facsimile apparatus 100 sends an EO
M (step S323), and waits until an MCF transmitted from the partner device is received (step S324: phase D), and thereafter, step S304 (phase B).
Return to.

By operating in this manner, as can be seen from the flow shown in FIG. 6, when the “maximum document width” exceeds the “recording width capability of the partner machine”, the image read at the same magnification is always output. To thin out (reduce) the image at the ratio of "recording width capability" / "maximum document width", the image is transmitted to the partner machine with an image of the same magnification. If the “maximum document width” does not exceed the “recording width capability of the partner machine”, the scanned image is always transmitted as it is at the scanning width (the recording width capability of the partner machine changes during communication). No). in this case,
Since the transmission is performed in accordance with the width of each page, it is possible to output to an appropriate sheet on the receiving side.

In the case of the example shown in FIGS. 5 and 6,
Since the “maximum document width” is automatically set when the document is stored in the SAF 23, the ADF is not set as shown in FIG.
It is not necessary to have a mechanism for detecting the "maximum document width" in 1 or to have the user input the "maximum document width".
