DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus having a function of transmitting a double-sided original or performing double-sided recording upon reception, and relates to an image communication apparatus such as a facsimile apparatus, a data terminal apparatus, and a multifunction apparatus.

[0002]

2. Description of the Related Art Heretofore, there has been known an apparatus of this type which has the following two configurations when transmitting and receiving a double-sided image of a document.

First, as a first configuration, when a double-sided original is read and transmitted, the front side, the back side, and the second side of the first page of the original are read.
The images are read sequentially, such as the front and back of the page,
The image data was sequentially transmitted in this reading order. On the other hand, on the receiving side, the front and back of the first page, the front of the second page,
It is recorded sequentially like back side ...
The image data is stored one by one while accumulating image data such as the front surface of the page, the front surface of the second page, the back surface of the first page, the back surface of the second page, and so on.

Further, as a second configuration, the transmitting side performs
The front side of the page, the front side of the second page, the back side of the first page, the back side of the second page, etc. are read one by one while accumulating the image data, and the image data is read from the front side, the back side of the first page, the second side. The page was sent sequentially, such as the front side, the back side, etc. On the other hand, on the receiving side, the front and back of the first page, the front of the second page,
Back side, etc. are recorded sequentially, or the front side of the first page,
The front side of the second page, the back side of the first page, the back side of the second page, etc. are recorded one by one while accumulating image data.

[0005]

However, in the above-mentioned prior art, the recording method on the receiving side cannot be confirmed on the transmitting side. To cope with this, it was necessary to prepare a sufficiently large storage image memory.

The transmitter and the receiver inform the transmitter and the receiver of the processing order of the back and front sides of a one-page document, so that the exchange processing between the back and front sides is matched between the transmitter and the receiver. A known system is disclosed in Japanese Patent Laid-Open Publication No.
244365) does not provide a system that matches the reading order and recording order over all pages in one communication unit as described above.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image communication apparatus which can transmit and receive double-sided image data with a simple configuration and can achieve a reduction in the capacity of a stored image memory. I do.

[0008]

According to the present invention, there is provided an image communication apparatus for transmitting and receiving image data, wherein a transmitter side comprises: first transmission control means for transmitting odd-numbered pages and even-numbered pages alternately; There is a second transmission control unit that performs batch transmission, and a determination unit that determines whether to transmit odd-numbered pages and even-numbered pages alternately, or collectively transmits odd-numbered pages and even-numbered pages based on the state of the receiver. Further, the receiver has first recording control means for alternately recording the front and back surfaces, and second recording control means for performing double-sided recording by both front surface simultaneous recording and back surface simultaneous recording. Then, on the transmitter side, the first
The transmission control means and the second transmission control means are appropriately selected, and the receiver side appropriately selects the first recording control means and the second recording control means at the time of reception, thereby enabling the double-sided image data to be obtained. Can be transmitted and received, and the conventional device configuration can be simplified. With such a configuration, it is possible to reduce the capacity of the storage image memory.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of a first facsimile apparatus in an embodiment in which the present invention is applied to a facsimile.

In FIG. 1, a CP for controlling the entire apparatus is provided.
U11 and RO storing control program of CPU11
M12, a RAM 13 used as a work area of the CPU 11, an operation unit 14 for inputting various keys by an operator, a double-sided reading control unit 15 including a scanner for reading double-sided originals, and a printer 16 for double-sided recording
, A modem (MODEM) 17 that modulates and demodulates transmitted and received data, and a line control circuit (NCU) 18.

Here, when a double-sided reading instruction is issued from the operation unit 14 before reading the original, the double-sided reading control unit 15 controls the original-conveying path and alternately reads the front side and the back side of each page. I do.

The double-sided recording control unit 16 controls the recording paper conveyance path when a double-sided recording instruction is given from the operation unit 14 before printing starts, or when a double-sided recording instruction is given from a transmission destination. The conveyance control for alternately printing the front and back surfaces of each page is performed.

FIG. 2 is a block diagram showing a configuration of a second facsimile apparatus in an embodiment in which the present invention is applied to a facsimile.

The second facsimile apparatus has substantially the same configuration as the first facsimile apparatus except for the reading control unit 25. That is, the CPU 21, the ROM 22, the RAM 23 of the second facsimile machine,
Operation unit 24, double-sided recording control unit 26, modem (MODE)
M) 27, a line control circuit (NCU) 28, a CPU 11, a ROM 12, a RAM 13,
Operation unit 14, double-sided recording control unit 16, modem (MODE)
M) 17 and a line control circuit (NCU) 18 having substantially the same configuration and function.

The reading control section 25 of the second facsimile apparatus reads only one side, and is different from the double-side reading control section 15 of the first facsimile apparatus in that point.

FIGS. 3 and 4 are explanatory diagrams showing the mechanism of data transmission and reception in the facsimile apparatus as described above.

In FIG. 3, a facsimile machine 31 is a facsimile apparatus with a double-sided transmission function as shown in FIG.
The AXB 32 is a facsimile apparatus with a two-sided reception (recording) function as shown in FIG. 1 or FIG. Also, 33
Is an exchanger.

Similarly, in FIG.
It is a facsimile machine without two-sided reception (recording) function.
The only difference is that the FAXB 32 of FIG. 3 is replaced.

Next, a description will be given of document reading, data transmission, and reception recording in FIGS. 3 and 4. FIG.

First, FAXA reads a double-sided document in the order of front page 1, back page 1, front page 2, and back page 2, and sequentially sends out the data as transmission data on the line.

On the other hand, on the receiving side, in the FAXB with the two-sided reception function, the two-sided data is recorded in the order of front page 1 and back page 1. The same applies to the front page 2 and the back page 2. On the other hand, in the FAXC without the duplex reception function, the front page 1 is recorded as the first page, the back page 1 is recorded as the second page, the front page 2 is recorded as the third page, and the back page 2 is recorded as the fourth page.

In the above operation, it may be determined independently whether or not to perform double-sided reading and double-sided recording even if there is no recognition as a double-sided original in both transmission and reception. This is because, as shown in FIG. 5, even when a fax is transmitted from the FAXD 51 without the duplex transmission function (FIG. 2) to the FAXB 32 with the duplex reception function, the receiving side may perform duplex recording without being aware of the original reading mode of the transmitting side. Because.

However, for example, as shown in FIG. 3, in order for the receiving side to record the original on the transmitting side faithfully, it is necessary to notify the receiving side of the reading mode of the original on the transmitting side.

As shown in FIG. 6, among the two-sided reading methods on the transmitting side, only the front side is read first,
Then, there is a method of continuously reading the back surface. On the other hand, on the receiving side, there is a method in which only the front side is first recorded in the double-sided recording and conveying method, and then the rear side is continuously recorded.

In both cases, any mode can be handled on the transmission side or the reception side by storing the image data in the memory and sorting the memory. However, in the case of a document having a large number of documents and a large amount of information, there are many cases where all the data cannot be stored in the memory.

Therefore, in this embodiment, the data transmission order as shown in FIGS. 3 and 6 can be switched in accordance with the recording function of the receiving destination.

FIG. 7 is a flow chart showing a procedure of transmission on the calling side by the G3 control means of the facsimile, and NSF (Non Standard Facilit).
ies Set-UP; non-standard setup data of a calling station) is an explanatory diagram showing an example of a frame configuration and an FIF configuration.

Next, a normal communication procedure will be described with reference to FIG.

In step S1, a dial is performed from the transmitting side.
Send a selection signal on the line. In step S2, the CED is returned from the receiving side. In step S3, the NSF
Will be returned. In step S4, the CSI is returned from the receiving side. In step S5, the receiving side further continues DI
S is returned.

In step S6, the NSS is transmitted from the transmitting side. In step S7, a DCS is transmitted from the transmitting side,
In step S8, a training signal is further transmitted. In step S9, the TCF is further transmitted. Step S10
Returns the CFR from the receiving side.

In step S11, following the training signal from the transmitting side, an image is transmitted in step S12, and at the end of the image, the RTC is transmitted in step S13. In step S14, an EOP signal indicating that all pages are completed is transmitted.

In step S15, the receiving side returns an MCF signal. In step S16, the transmitting side sends out the line disconnection signal DCN and ends the communication.

Next, the NSF and NSS in step S3
The HDLC room configuration will be described. In FIG. 7 (B), F in a frame is a flag used for synchronization, AF is an address field indicating a station address, CF is a control field indicating various identifications and a transmission / reception sequence number of a frame, and FCF is a DIS or NSF or the like. A facsimile control field for storing a code of each control signal, FIF is a facsimile information field for carrying function information when a control signal such as DIS or NSF is used in the FCF, and FCS is a frame check field used for error detection.

Here, FIF (Frame Information Field)
7), as shown in FIG. 7 (C), since the fourth octet and subsequent octets are reserved as free areas, information such as the presence or absence of the double-sided reception function and the presence / absence of the front-side reception function at the time of both-sided reception are stored here. By writing, the extension function of the receiving side can be notified to the other party.

Similarly, the transmission side can notify the other party of the extension instruction of the transmission side by writing information such as the presence / absence of the presence / absence of the two-sided transmission instruction and the presence / absence of the front side batch transmission instruction at the time of the two-sided transmission in the NSS.

In FIG. 3, when the NSF of the FAX B has the double-sided reception function and does not have the front side batch reception function, the data transmission order is as shown in the figure. Also, when there is batch reception on the front side, the data transmission order is as shown in FIG. By doing so, there is no need to store all page memories on the receiving side, and the memory capacity can be reduced.

As for the memory storage capacity on the transmission side, the facsimile apparatus having only the front / back alternate reading function does not require the storage capacity of all pages. In addition, since facsimile apparatuses having the front-side batch reading function are overwhelmingly likely to have no two-sided reception function at the receiving side, it is necessary to have either a front-back alternate reading function or an all-page storage memory. .

In the above embodiment, the facsimile apparatus has been described as an example. However, the present invention can be widely applied to various types of image communication devices such as a data terminal device and a multifunction device having an image communication function. .

The above control operation is performed by the CPU 1
1 and 21 are executed based on control programs stored in ROMs 12 and 22. Similar control programs are stored in various storage media such as a floppy disk, a hard disk, or an optical disk or a memory card. The storage medium may be read by a dedicated reading device, and the control program may be loaded into the device to execute the above-described control.

[0040]

As described above, according to the present invention,
A first transmission control means for transmitting an odd-numbered page and an even-numbered page alternately; a second transmission control means for simultaneously transmitting an odd-numbered page and an even-numbered page; an odd-numbered page and an even-numbered page; A first recording control unit for alternately recording the front side and the back side; a first recording control unit for alternately recording the front side and the back side; By having the second recording control means for performing both-side recording by both recording, the transmitter side appropriately selects the first transmission control means and the second transmission control means in accordance with the determination means, and On the receiving side, transmission and reception of double-sided image data can be performed by appropriately selecting the first recording control means and the second recording control means at the time of reception.

Accordingly, the original document on the transmitting side can be faithfully reproduced on the receiving side, the configuration of the apparatus can be simplified, and the capacity of the storage image memory can be reduced. .
