Abstract

PURPOSE:To attain picture transmission without waste at a high speed by sending no delimiter signal representing delimiter in the unit of prescribed picture by sending a picture signal, when no recording paper cutter is provided to a picture transmission destination. CONSTITUTION:A main control section 1 consists of a cutter presence discrimination section 1a for a sender's destination to discriminate the provision of a cutter of a destination facsimile equipment, a self cutter provision discrimination section 1b discriminating the provision of a cutter of its own facsimile equipment and a delimiter signal generating section 1c generating a delimiter signal delimiting each page based on the result of discrimination. When a cutter presence discrimination section 1a for the sender destination informs that no cutter is provided to an opposite destination, the sender sends the picture without a delimiter signal. Thus, useless procedure and time is omitted to send the picture quickly.

Description

[Detailed Description of the Invention] [Summary] Regarding an image transmission method in which, when transmitting an image, the transmitting side transmits to the receiving side a delimiter signal indicating the delimitation of the image corresponding to a predetermined unit, the transmitting side transmits a cutter signal to the receiving side. The purpose of this method is to provide an image transmission method that can transmit images at high speed and without waste without exchanging unnecessary delimiter signals when there is no need to exchange unnecessary delimiter signals. After the initial steps of the response operation, if the receiving side notifies the sending side that the cutter for cutting the paper is empty, and the sending side determines that the cutter will not be cleared, the sending side does not send the delimiter signal and displays the image. The purpose of this is to transmit.

(Industrial Application Field) The present invention relates to an image transmission method for a fujikusu device, etc., and in particular, when transmitting an image, the transmitting side sends a message to the receiving side.
The present invention relates to an image transmission method for transmitting a delimiter signal indicating a delimiter of an image corresponding to a predetermined unit.

(Conventional technology) Conventionally, there has been an image transmission method shown in FIG.

This method uses a 03 machine sofa fabrication device (as shown in Fig. 4).
This is a transmission procedure for a high-speed factor processing machine group for document transmission using telephone lines classified according to CCITT recommendations, in which the sending side sends a paging signal to the destination's factor processing device in step SAI. to make a call.

The factor calculation device on the receiving side of the called party called in step SA2 sends a response signal (CED) to the calling signal.
A signal; a called station confirmation signal; a DIS signal; a digital identification signal that identifies the standard CCITT capability of the facsimile machine on the signal receiving side) is output.

In step SA3, the transmitting side transmits to the receiving side a DO3 signal for issuing a digital setting command in response to the standard function identified by the DIS signal.

In step SA4, the transmitting side transmits a training signal to the other party.

In step SA5, the receiving side receives a training signal (TCF;
) When receiving the training signal (training check signal), it outputs a CFR signal indicating that the reception result of the training signal is positive and preparation for reception is complete.

Thereafter, the transmitting side will transmit the image signal to the other party.

At this time, in the conventional factor cutting device, whether or not there is a cutter for cutting the recording paper on the receiving side, as shown in FIG. The image signal (PIX
;Picture Element), in step SAT (or step 5A15) an MPS signal (M
ultipage Signal (represents a page of factor processing information, returns to the beginning of phase C as soon as confirmation is received) is sent to the other party.

Upon receiving the MPS signal, the destination factor shaving device sends the message confirmation signal (MG
E; Message Comfirm) is to be output, and if the recipient's receiving device turns on the cutter, the recording paper is cut in step SA9 in response to reception of the MPS signal, and the recipient's If the device does not have a cutter, the recording paper will not be cut even if the MPS signal is received.

When the transmitting side receives the confirmation signal, if the other party has a cutter, it transmits an image signal in step 5AIO (even if the other party does not have a cutter, it transmits an image signal), and also transmits a delimiter signal in step 5A11. will be sent, and the procedure described above will be repeated (step 5).
A12.13).

[Problem to be solved by the invention]

By the way, in the conventional factor calculation device,
Regardless of whether the destination device has a cutter for cutting recording paper or not, after transmitting the image signal for one page, it sends an MPS signal that indicates the division of the image signal. I'm trying to send it.

However, if the other party has a cutter,
If you do not have the recording paper, even if you send the MPS signal and wait for the output of a confirmation signal (MCE signal) that confirms the reception of the MPS signal from the other party, the recording paper will not be cut and it will be received as a single document. This eliminates the problem that the transmission time is extended by that amount, which is wasteful.

Incidentally, while image signals are transmitted at 9600 bits/s, frame signals such as the MPS signal and MCF signal are transmitted at 300 bits/s. Exchange of the MPS signal etc. occupies a large amount of time.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an image transmission method that can quickly transmit images without unnecessary procedures and time.

[Means for Solving the Problems] In order to solve the above-mentioned technical problems, the present invention, as shown in FIG. In an image transmission method that transmits a delimiter signal indicating the delimitation of an image, after the initial procedure of the calling operation by the transmitting side and the corresponding operation by the receiving side (SL),
The receiving side notifies the sending side of the presence or absence of the cutter (S2), and if the sending side determines that the cutter is not present (S3)
, the transmitting side transmits images without transmitting a delimiter signal.

(Operation) According to the present invention, when transmitting an image, as shown in FIG. Thereafter, in step S2, a notification is received as to whether or not the other party's device has a cutter used to cut the recording paper.

The reason why the expression "after the initial procedure is completed" is that it is not possible to receive notification of the presence or absence of a cutter unless the other party is identified through the initial procedure.

If it is determined in step S3 that the other party has a cutter based on the notification, the process proceeds to step S5, and as in the past, after transmitting a predetermined unit of image signals, a delimiter signal indicating the unit is sent to the other party. will be sent to.

Here, the "predetermined unit" is the size of the paper on which the original image of the image to be sent is recorded (for example, A4, A5
．． It is a unit of data amount determined based on A6, etc.), and is called a normal page. Further, the "delimiter signal" is a signal indicating that the transmission of the image for the corresponding unit has been completed.

On the other hand, if it is determined that the destination device does not turn the cutter right, the process proceeds to step S4, and after transmitting the predetermined unit of image signals, the delimiter signal is not transmitted.

Therefore, when the cutter is not on the other party's side, there is no need to exchange a delimiter signal and a confirmation signal for reception of the delimiter signal from the other party's side, thereby speeding up the communication.

〔Example〕

Next, examples of the present invention will be described.

FIG. 2 shows a fujikusu transmitter/receiver according to an embodiment of the present invention.

As shown in the figure, this device includes a main control section 1 composed of an MPU and programs that perform various controls regarding the facsimile device, a reading section 2 that reads original images,
A recording section 3 performs recording on recording paper, a cutter 4 performs cutting of the recording paper, an image processing section 5 performs image conversion processing such as image restoration or image compression, and a signal is transmitted via line 8. The line controller 6 controls transmission and reception, and the memory 7 stores image data to be transmitted or received image data.

As shown in the figure, the main control section 1 includes a destination cutter presence/absence determination section 1a that determines whether or not a cutter is present in a destination fuji shaving device, and a self-control unit such as a register that determines whether or not a cutter is present in its own fuji shaving device. Cutter presence/absence determination section 1b
and a delimiter signal generating section 1c that generates an MPS signal as a delimiter signal indicating the delimitation of each page based on the determination result.

Further, the image processing section includes a processing section 5a configured by an MPU and its program that performs processing such as image signal compression, and a buffer memory 5b that temporarily holds the transmitted image signal to be processed. As shown in the figure, the line control section 6 controls a modem section 6a and a line interface section 6b.

The operation of this device will be explained based on the flowchart in FIG.

As shown in the figure, when transmitting an image using the G3 fujikusu device according to this embodiment, step SJI
According to instructions from the operator, the main control section 1 sends a calling signal to the other party via the line 8 to the line control section 6 to make a call.

Upon receiving the signal, the other party's fujikusu device sends a response signal (CED) in response to the call in step SJ2.
, NSF, DIS) to the transmitting side.

Here, as mentioned above, the CHD signal is a called station confirmation signal, a network control signal in facsimile communication, and a signal indicating that the called party is a facsimile terminal (silent voice control). NSF signal is CCI
In the transmission control procedure of TT Recommendation T, 30, the NSF signal is a control signal indicating a specific request that exceeds the scope of the recommendation in the T series, and the NSF signal is at least a 2-byte FIF (Facsimile Information
It has an identification code in the first byte and a sublayer coat in the second byte, and has a non-standard function identification signal (non-standard f field).
abilities).

In this embodiment, the signal notifies the transmitting side of information as to whether or not the other party's device has a cutter.

Furthermore, the DIS signal (Digital Identif
cationSignal), the receiving device is CCI
This is a signal indicating whether the protocol is different from the standard protocol recommended by the TT, and in this embodiment, the standard protocol is used.

When the transmitting side receives the response signal through the line control section 6, in step SJ3, the transmitting side transmits to the receiving side a DO8 signal for issuing a digital setting command in response to the standard function identified by the DIS signal.

In this way, when the communication procedure becomes possible between the transmitting side and the receiving side, the training signal (TCP) is transmitted from the transmitting side to the other party in step SJ4.

Here, the "training signal" refers to a signal in a predetermined format that is experimentally transmitted to the receiving side in order to confirm the transmission state of the line signal.

The receiving side checks whether the signal was received without error,
If it is received without error, a CFR signal (Con
firm) will be notified to the sending side.

The transmitting side uses the destination cutter presence/absence determination unit 1a of the main control unit 1 to determine whether or not a cutter exists at the destination based on the NSF signal output from the destination,
If it is determined that there is a cutter, the process proceeds to step SJ7, where the image processing unit 5 performs processing such as compression on the image read from the original image spread over multiple sheets by the reading unit 2, as in the conventional case. Then, the line control section 6 transmits an image signal.

When the image for one page is transmitted, an MPS signal as a delimiter signal is sent to the other party in step SJ8, and when a confirmation signal MCE signal is received from the other party in step SJ9,
In step 5511, the image signal for the next page is transmitted, and the above-described procedure is repeated from Stellaf 5J12 onwards.

On the other hand, a case will be described in which the transmission destination cutter availability determination unit 1a of the transmission side main control unit 1 determines that there is no cutter at the destination based on the NSF signal in step SJ6.

In this case, the process proceeds to step 5J13, where image signals for a page as a predetermined unit are transmitted to the other party. Without transmitting the MPS signal as a delimiter signal indicating the end, the process immediately proceeds to step 5J14, and the image signals for the next page are transmitted to the other party.

Therefore, on the image receiving side, the image is recorded as a single document with the recording sheets connected without cutting the recording sheets.

In the above description, an image obtained by reading an original image by the reading unit 2 is transmitted, but an image stored in the memory 7 may be transmitted. Furthermore, since the device shown in FIG. 2 has a cutter 4, if there is a calling operation from another device and the device transmits the NSF signal as the called device, the register etc. The configured self-cutter presence/absence determination section 1b determines that the device has a cutter, and the delimiter signal generation section 1c notifies the other party of this fact.

Furthermore, in the above explanation, images are sent without sending a delimiter signal when there is no cutter at the destination, but even if a cutter is present, high-speed transmission or paper If the other party desires output in a connected state, the other party can notify the sending side of this by an NSF signal.

〔Effect of the invention〕

As explained above, in the present invention, if the destination to which the image is to be transmitted does not have a cutter for cutting the recording paper, the delimiter signal indicating the delimitation of the predetermined unit of the image is not transmitted. Then, image signals are transmitted.

Therefore, when the other party does not have a cutter, the exchange of unnecessary delimiter signals, etc. is omitted, which simplifies the procedure, reduces transmission time, and enables high-speed image transmission without waste. It will be possible.
