Abstract

PURPOSE:To prevent wasteful transmission by determining the transmitting stop based upon a data quantity of message information which can be processed by the receiver and a transmitting message information data quantity and stopping transmission based upon the determined result data. CONSTITUTION:It is investigated whether or not a control signal NSF is sent from a receiver 2 and a transmitting picture signal becomes equal to picture signal data for one line from capacity data based upon a memory 6. At the time of ''YES'', a picture signal 100 ''subsequent message.'' is sent, a control signal EOM is sent and a transmission control procedure to transmit a remaining picture signal is started. Thus, the picture '*subsequent message.' can be obtained at the final part of a recording paper 201 from the receiver 2. In this way, after a transmitter 1 transfers message information of a memory capacity or below of the receiver 2, transmitting is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a facsimile device that can avoid transmitting useless message information C (referring to image signals and character codes for original documents).

[Technical background of the invention]

In conventional facsimile devices, the transmitter (the facsimile device that sends image signals and other message information) and the receiver (the facsimile device that receives image signals and other message information) Regardless of whether or not it is possible to process up to a certain amount of message information, it is possible to transmit the message information and use the control signal of the transmission control procedure sent from the receiver after the transmission is completed.
It was designed to check whether the message information was received correctly.

[Problems with background technology]

For this reason, there are cases where the receiver has only a small amount of recording paper remaining and cannot record all the message information even if it receives message information, or when the memory capacity of the receiver is small and the transmitter Even if all of the message information transmitted from the system cannot be stored, the message information is transmitted and the result is known after the transmission is completed, so there is a drawback that the transmission is wasted.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks of conventional facsimile machines, and its purpose is to prevent wasteful transmission due to the amount of message information that can be processed by receivers. To provide a facsimile machine.

[Summary of the invention]

Therefore, in the present invention, the r-
Transmission stop determining means for determining whether to stop transmission based on the evening scenery and the amount of data of message information to be transmitted; and transmission control for stopping transmission of said message information based on result data determined by said transmission stop determining means. The above object is achieved by configuring a facsimile machine to include transmission control procedure execution means for executing the procedure.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a facsimile system using a facsimile apparatus of the present invention. In the figure, 1 indicates a transmitter and 2 indicates a receiver. The transmitter 1 and receiver 2 are connected by a half-duplex line 3. The transmitter a1 and the receiver 2 are provided with transmission control units 4 and 5, and these transmission control units 4 and 5 transmit and receive control signals according to the G3 machine transmission control procedure recommended by CCITT. The transmission control unit 5 includes the capacity data of the memory 6 in a control signal NSF and transmits the control signal NSF. Upon receiving the control signal NSF, the transmission control unit 4, which is a transmission control procedure execution means, takes out the capacity data from the memory 6 and stores it in the memory 7. Further, 8 indicates an encoder. encoder 8
receives the image signal before being encoded, encodes it, and sends it out. The transmitted image signal is received by the receiver 2 via the line 3 and stored in the memory 6. Reference numeral 9 denotes a counter, which counts the amount of encoded image signals output from the encoder 8 and outputs cumulative value data a as the counting result. Reference numeral 10 denotes a comparator which is a means for determining transmission stop; comparator O receives accumulated single-direction data a of the image signal to be transmitted from the counter 9, also receives capacity data b of the memory 6 from the memory 7, and compares these data. to compare. Accumulation (When the direct data a becomes equal to the capacity obtained by subtracting the capacity corresponding to one line of characters from the capacity data b, the comparator 10 outputs the first signal C. As a result, the memory (not shown) An image signal for one line indicating "there is a continuation message" stored in is sent to the encoder 8. When this image signal is encoded and output, the accumulated one-shot data a is 9, which is equal to Mf-ta b, and the comparator 10 outputs the second signal d. Upon receiving this, the transmission side fI 11 section 4 sends out a control signal EOM in order to stop transmitting the image signal. Thereafter, control signals are sent and received to and from the transmission control section 5 in order to transmit the remaining image signals next.

As described above, when an image signal is transmitted in a facsimile system that has been constructed (1), the flowchart shown in FIG.
The operation proceeds as shown in FIG. 3, control signals are transmitted and received as shown in FIG. 3, and a recorded image as shown in FIG. 4 is output.

Then, a control signal NSF is sent from the receiver 2, and it is checked based on the capacity data of the memory 6 whether the transmitted image signal is equal to the image signal data of one line from the capacity data (Stella 7'IO1 to 103). .

If YES, a picture signal 10 indicating that there is a continuation of the message is sent.
0 is transmitted, a control signal EOM is transmitted, and a transmission control procedure for transmitting the remaining image signals is entered (steps 104 to 106). As a result, from receiver 2,
An image is obtained in which the last line of the recording paper 201 is printed with "Continued message available".

As described above, according to this embodiment, after transmitting the message information that is less than the memory capacity of the receiver 2, the transmitter 1 stops transmitting the message information, and transmits the remaining message information next. Therefore, there is no wasted transmission. Furthermore, since the existence of the continuation message information is output as a recorded image of the receiver 2, it is convenient to clearly identify the presence or absence of the continuation message information.

In this embodiment, image signals exceeding the memory capacity of the receiver are prevented from being transmitted, but image signals exceeding the amount of recording paper set in the receiver are prevented from being transmitted. It's okay. In this case, the NSF includes data on the number of lines recordable on the remaining portion of the recording paper and is sent to the transmitter. Furthermore, in a facsimile apparatus in which the image signal memory for the image signal sent from the encoder 8 of the embodiment is included in the transmitter 1, the amount of image signals stored in this image signal memory is If the amount of image signals is greater than the capacity of the memory 6 or the remaining amount of recording paper, a transmission control procedure may be performed in which the line is disconnected without transmitting the image signals.

Further, when the line is to be disconnected, a message image signal indicating the reason may be transmitted before the line is disconnected.

Furthermore, when the image signal is transmitted in multiple transmissions, the image signals of the last few lines of the first transmission may be transmitted at the beginning of the second transmission, and so on. Further, it is not necessary to transmit an image signal indicating that there is a continuation message.

〔Effect of the invention〕

As explained above, according to the present invention, the amount of message information that exceeds the amount of message information that can be processed by the receiver is never transmitted, so there is no unnecessary transmission, and unnecessary line exclusive use is avoided. There is no need to waste line usage fees.
