Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a data communication system in a data communication device such as a facsimile machine or a telex machine.

[Technical background of the invention]

Conventionally, facsimile machines and telex machines often transmit multiple pages of document data from the sending device to the receiving device. The receiving side can determine whether the data of the current page is being received, and whether reception of data of all pages has been completed.

By the way, recently, this caged data communication device temporarily stores transmitted data in a storage unit such as a memory, and simultaneously transmits the stored data to multiple receiving devices, or sequentially stores data in multiple receiving devices. Some devices are designed to improve line usage efficiency by transmitting data.

[Problems with background technology]

However, in a data communication device equipped with such a simultaneous broadcast communication function or a sequential broadcast communication function, even if the total number of pages to be transmitted and the serial number of 6 pages are inputted to the manuscript and the transmission data is input, this transmission The data is temporarily stored in the storage unit, and when the storage amount reaches a certain amount, it is sent to the receiving device along with the transmission data manually input at other times (that is, it is serialized and transmitted). Therefore, there is a problem in that the receiving device cannot determine the amount of data to be received or the amount of time it will take to complete the receiving operation. at the same time,
When a transmitting device performs broadcast communication to a plurality of destinations in sequence, there is a problem in that the operator on the transmitting side cannot determine when the sequential broadcast communication will end.

[Purpose of the invention]

The present invention has been made to eliminate the above-mentioned problems, and its first purpose is to provide a data communication system that allows a receiving device to easily determine the amount of data to be received. A second object is to provide a data communication system that allows the transmission side device to easily determine the amount of data to be transmitted.

[Summary of the invention]

In order to achieve the above-mentioned first object, the present invention provides a detection means for detecting the amount of transmission data to be transmitted in the transmitting side device, and a display for displaying the remaining amount of received data in the receiving side device. The transmitting device transmits information indicating the amount of transmitted data detected by the detection means to the receiving device prior to transmitting the transmitted data, and the receiving device receives the above information and the amount of received data that has been received. The remaining amount of received data is calculated based on this and displayed on the display means.

In addition, in order to achieve the second objective, a detection means for detecting the amount of transmission data to be transmitted and a display means for displaying the remaining amount of transmission data are provided in the transmission side device, and the amount of transmission data that has been transmitted is The remaining amount of transmission data is calculated based on the amount of transmission data detected by the detection means and the amount of transmission data detected by the detection means, and is displayed on the display means.

゜An image feeding mechanism section 6 that feeds the transmission document placed on the reading section 1. An image receiving mechanism section 7 that records an image based on the received facsimile image signal. Communication-related information control unit 8. Calculates the remaining amount of received data based on the information representing the amount of received data sent from the transmitting side device, and displays it on the display of the operation panel 2. It is equipped with a modem 9 and a network control unit (NCU') 10 for making a line connection with the transmitting side device.

The sending facsimile device has a similar circuit section, and
It is provided with a storage section that accumulates facsimile image signals to be transmitted, and a detection section that detects the amount of transmission data to be transmitted (therefore, the transmitting side facsimile device is not shown).

In the above configuration, the operation of transmitting facsimile image signals for, for example, two pages of a document stored in the storage section of the sending device to the receiving device will be described with reference to FIGS. 2 to 4.

First, when a line connection is established between the sending device and the receiving device, the receiving device receives a digital identification signal DIS in response to a call from the sending device, as shown in the signal sequence diagram in Figure 2.
(a signal indicating that the receiving device has a CCITT standard receiving function) and a non-standard function identification signal N8F signal (a signal indicating a function other than the standard function) are returned to the transmitting device.

The transmitting device that receives these signals DI8 and N8F,
Digital command signal DC8 (command signal for setting some functions among standard functions) and non-standard function setting signal N
58 (command signal for setting some functions among functions other than standard functions) is returned.

At this point, the signal N88 is transmitted to the receiving device in the frame configuration shown in FIG. .

Next, the sending device checks the transmission speed using the training check signal TCP, and when the receiving device returns the reception preparation confirmation signal CF, the facsimile image of the first page of the document stored in the storage section is displayed. The receiving side device (sends the signal FIX).

When the transmission of the facsimile image signal of the first page of the original is completed, a message end signal ROM indicating this is sent.
, and then proceed to transmit the second page.

Transmission of the second page is performed in the same sequence, and when the transmission is completed, a procedure end signal BOP indicating that there is no facsimile image signal to be transmitted is transmitted, and this signal E
When the message confirmation signal MCF for the OP is returned, a disconnection command signal DCN is sent to release the line connection.

Note that F, A, and C shown in FIG. 3 indicate a flag sequence, an address field, and a control field preceding the HLDC input field.

In this way, the receiving side apparatus which receives information on the number of pages of the received facsimile image signal by the signal NSS inputs this information on the number of pages to the communication-related information control section 8. Then, the control section 8 sets the input number information to N, and performs the processing shown in the flowchart of FIG. That is, when the signal NSS is received (step 20), the information N of the number of pages included in this signal NSS is read (step 21), and this information N is transferred to the operation panel 2 to display the number (step 22). ). Next, when the message terminal signal ROM is received, "1" is subtracted from the value of the information N (step 24), and the remaining number of received pages is displayed on the operation panel.
display on the display. After this, the procedure end signal B
If OP is received (step 25), "1" is subtracted from the latest remaining amount value N to set the remaining amount display to rOJ, and the control of the remaining amount display is ended.

Therefore, the display on the operation panel 2 can easily determine the number of pages of the document (converted to how many pages remain) based on the facsimile image signal sent from the sending device.

If the receiving operation ends before the remaining amount display reaches rOJ, it can be determined that some kind of abnormality has occurred.

In this case, facsimile communication uses (
For example, since the image signal is transmitted in units of blocks divided into units of 512 bits, the remaining amount may be expressed in units of blocks and displayed on the receiving side. Furthermore, if the total number of blocks and the transmission speed are known, the time required until the end of transmission can be known, so the remaining amount may be expressed as the time until the end of transmission and displayed on the receiving side. In addition, the remaining amount may be displayed using the number of words made up of a plurality of data bits.

On the other hand, if such a remaining capacity display function is added to the sending device, the waiting time can be easily determined when inputting new transmission data on the sending side.In this case, the sending device can If broadcast communication is to be carried out, in addition to the remaining amounts as described above, the number of untransmitted destinations may be displayed as the remaining amount.

In addition, it would be even more effective if the remaining capacity could be configured so that it is possible to select whether to display the number of units or the time until completion.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the total amount of communication data and the remaining amount are displayed on the transmitting side device or the receiving side device. It is possible to very easily determine how much time it will take to complete the process, which has the effect of eliminating unnecessary waiting time for the operator.
