Thus, the operator of the reception device can know whether the reception image is variably multiplied or not or whether there is loss in the reception image or not without fail.

Description

[Detailed description of the invention] [Technical field] The present invention relates to a method of controlling a facsimile transmission device.

[Prior Art] Generally, in a facsimile machine, when the size of a transmission document set on the sending side is larger than the size of an image that can be received on the receiving side, the following problem occurs.

In other words, a facsimile machine equipped with a scaling function uses the scaling function to reduce the transmitted image and transmit it to the receiving device, but the receiving device side does not check whether the received image is in a reduced state or not. cannot be determined.

Furthermore, if the transmitting device does not have a variable magnification function, only a portion of the image that matches the size of the receiving device is transmitted, resulting in the inconvenience that omissions occur in the received image.

[Purpose] The present invention has been made in order to eliminate the disadvantages of the prior art, and provides a method for controlling a facsimile transmitter that allows the receiving side to reliably check the relationship between the size of the transmitted document and the size of the received image. The purpose is to provide.

[Configuration] In order to achieve this object, the present invention provides size relationship display information that displays in text the relationship between the size of the transmitted image and the receivable size of the receiving device obtained in the pre-transmission procedure at the leading edge of the transmitted image. It was added to the .

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a facsimile machine according to an embodiment of the present invention.

In the figure, a system control unit 1 controls the entire facsimile machine, a scanner 2 is for reading an image of a document at a predetermined resolution, and a plotter 3 is for reading a received image etc. at a predetermined resolution. This is for recording and outputting at high resolution.

In this case, the scanner 2 can read up to a 13-size original, and the plotter 3 can record and output an 84-size image at the same size.

In addition, the scanner 2 has a function of detecting the size of the read document and notifying the system control unit 1 of it, and the plotter 3 detects the size of each recordable image (usually the width size of the roll recording paper) and It has a function of notifying the system control unit 1 of the following information.

The character generator 4 generates dot patterns constituting graphic characters. This character generator 4 is used when adding identification information (described later) to the leading edge of a transmitted image.

The operation display section 5 includes various operation keys for the operator to operate the facsimile machine, and a display with a large degree of display freedom for displaying operation guidance information and the like.

The image processing section 6 is for scaling the transmitted image to a size that can be received by the receiving device, and the encoding/decoding section 7 is for encoding and compressing the image data and converting the encoded and compressed image data. The image data is decoded into the original image data.

The communication control unit 8 executes a predetermined facsimile transmission control procedure to transmit images to the other party's station, and the modem 9 can use a public telephone line, which is an analog line network, as a transmission line. The network control device 10 is used to connect a facsimile device to a public telephone line network. Note that this network control device 10 has an automatic call originating and receiving function.

These system control section 1, scanner 2, plotter 3, character generator 4, operation display section 5, image processing section 6. Encoding/decoding section 7. and.

The communication control units 8 exchange data with each other via the system bus 11.

As shown in FIG. 2, this facsimile machine includes transmission identification information TT1. One image is transmitted with size identification information SZI indicating the relationship between the size of the transmitted original and the size of the received image and page number information PGN indicating the number of pages added.

The transmission identification information τTI consists of the name of the installation location of this facsimile machine, etc., and is stored in advance in the system control unit l.

Further, the size identification information SZI indicates the relationship between the size of the transmitted document detected by the scanner 2 and the receivable size notified by the receiving side in the pre-transmission procedure, an example of which is shown in Fig. 3. Shown in (a) to (g).

That is, the size information SZI is when the facsimile machine is not set to a reduction prohibition state.

If the size of the original to be sent is 13 and the receivable size is 84, select 1M3 → B4, and if the size of the original to be sent is 13 and the receivable size is A4, select ``A3 → A4''. , if the size of the original to be sent is 84 and the size that can be received is 84, change "B4 → B4", and the size of the original to be sent is 84.
If the size that can be received is A4, @B4→A4''
, the size of the original to be sent is A4 and the size that can be received is A4.
In the case of paper size, select A4→A4" respectively.

In addition, when the facsimile device is set to prohibit reduction, if the size of the original to be sent is 84 and the receivable size is 84, "B4 → B4" will be received, and if the size of the original to be sent is 4 If the available size is ＠4, please use ＠A4→
If the size of the original to be sent is 13 and the receivable size is 84, there may be gaps in the received image.
If the receivable size is A4, select 1→A4←" to indicate that there are omissions in the received image.

Consider the case where image information is transmitted from this facsimile device to another facsimile device with the above configuration.

The operator of this facsimile machine (hereinafter referred to as a transmitter) sets a document to be sent on the scanner 2 and inputs the destination's telephone number from the operation display section 5.

When image information transmission is started, system control section 1 transfers the input telephone number to communication control section 8 to start image information transmission.

As a result, the communication control section 8 transfers the notified telephone number to the network control device 10 to make a call to the destination.

As a result, when the destination facsimile device (hereinafter referred to as the receiving device) is called and a transmission line is established, the receiving device first responds with a called station identification signal CHD, and then, as shown in FIG. It responds to the transmitting device with a digital identification signal DIS for notifying standard terminal functions and a non-standard device signal NSF for notifying non-standard terminal functions.

Thereby, the transmitting device can determine the function of the receiving device from the contents of the digital identification signal DIS and the non-standard device signal NSF.
and identify the receivable size.

Then, the function to be used for image information transmission at that time is designated by the non-standard device setting signal NSS. □゛Next,
After executing the training check TFC, the transmitting device starts reading the transmission document set in the scanner 2 when the receiving device responds with a reception preparation confirmation signal CFR.

Scanner 2 scans the original to be sent once just before starting scanning.
When a sheet is input, its size is determined and notified to the system control unit 1.

As a result, the system control unit 1 selects the size shown in FIG. 5(a) based on the transmission original size TZ notified by the scanner 2 and the receivable size RZ determined in the pre-transmission procedure.

The process (b) is performed to determine the magnification of the read image and the contents of the size information SZI.

That is, the system control unit 1 first sets a reduction prohibition state in its own terminal. (Judgment 101)
)1 If the result of judgment 101 is No, check whether the receivable size RZ is 84 size (judgment 102),
If the result of judgment 102 is YES, the transmission document size T
It is checked whether Z is A3 size (determination 103).

If the result of the judgment 103 is YES, "A3→B4" is selected as the size information SZI, and its magnification ratio is set in the image processing unit 6 (process 104).

If the result of judgment 103 is NO, check whether the transmitted document size TZ is A4 size (judgment 105).
.

When the result of the judgment 105 is YES, A4→A4'' is selected as the size information SZI, and the image processing section 6 is not used at that time (process 106).

When the result of judgment 105 is No, the size information S
B4→B4'' is selected as the ZI, and the image processing section 6 is not used at that time (process 107).

When the result of judgment 102 is No, it is checked whether the transmitted original size TZ is A3 size (judgment 108),
When the result of the judgment 108 is YES, A3→A4'' is selected as the size information SZI, and the variable magnification is set in the image processing unit 6 (process 109).

When the result of judgment 108 is No, it is checked whether the transmitted original size TZ is 84 size (judgment 110);
When the result of the determination 110 is YES, B4→A4'' is selected as the size information SZI, and the variable magnification is set in the image processing unit 6 (process 111).

When the result of determination 110 is No, size information S
"A4→A4" is selected as the ZI, and the image processing unit 6 is not used at that time (processing 112).

Further, when the result of judgment 101 is YES, it is checked whether the receivable size RZ is 84 size (judgment 1).
13), when the result of judgment 113 is YES, it is checked whether the transmitted document size TZ is A3 size (judgment 114), and when the result of judgment 114 is YES,
"→B4←" is selected as the size information Sz, and at this time the image processing section 6 is not used (process 115).

When the result of judgment 114 is NO, it is checked whether the transmitted document size TZ is A4 size (judgment 116),
When the result of the judgment 116 is YES, "@A4→A4" is selected as the size information SZI, and the image processing section 6 is not used at that time (process 117).

When the result of judgment N116 is No, size information S
"B4→B4" is selected as the ZI, and the image processing unit 6 is not used at that time (process 118).

When the result of judgment 113 is NO, it is checked whether the transmitted original size TZ is A4 size (judgment 119),
When the result of the judgment 119 is YES, "A4→A4" is selected as the size information SZI, and the image processing section 6 is not used at that time (process 120).

When the result of judgment 119 is NO, size information S
1→A4←1 is selected as ZI, and the image processing unit 6 is not used at this time (processing 121).

After setting the size information SZI and the scaling factor in this way, the system control unit 1 transfers the image signal read out from the scanner 2 to the image processing unit 6 to change the scaling, and then sends the image signal to the image processing unit 6. The scaled image signal outputted from the encoder/decoder 7 is transferred to the encoder/decoder 7 to form encoded and compressed image information, and the image information is transmitted to the receiving device.

In addition, in the image signal after scaling, the portion corresponding to the display area of the transmission identification information TTI, size identification information SZI, and page number information PGN is the area corresponding to the display area of the transmission identification information TTI, size identification information SZ1 . Then, the character generator 4 generates a dot pattern of graphic characters that displays the page number information PGN, and transfers it to the encoding/decoding unit 7 in a state where it is replaced with the contents converted into raster data.

However, if the image processing section 6 is not used.

The image signal read out from the scanner 2 is directly transferred to the encoding/decoding section 7 to be encoded and compressed.

When the transmission is finished, the message end signal RO
Send M. On the other hand, when the receiving device normally completes image reception and responds with a message confirmation signal MCF, it transmits a line disconnection command signal DCN, disconnects the line, and ends image information transmission.

As a result, the received document received by the receiving device and recorded and output has the transmission identification information TTI and the size identification information SZI.
, and page number information PGN are recorded, so
The operator of the receiving device can reliably know whether the received image has been scaled or whether there are any omissions in the received image.

In the embodiments described above, the present invention is applied to a facsimile machine having a variable magnification function, but the present invention can be similarly applied to a facsimile machine that does not have a variable magnification function.

[Effects] As described above, according to the present invention, size relationship display information that displays in text the relationship between the size of the transmitted image and the receivable size of the receiving device obtained in the pre-transmission procedure is displayed at the leading edge of the transmitted image. This has the advantage that the receiving side can reliably check the relationship between the size of the transmitted original and the size of the received image.
