Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile communication system, and more particularly to a facsimile communication system that allows program information to be sent from a sender to a receiver to be changed after the sender starts operating.

For example, in a facsimile communication system intended for unattended operation on the receiving side, it is necessary to transmit program information such as resolution, paper size, number of original sheets, and transmission speed from the sending side to the receiving side before transmitting calligraphic information. be.

In this case, the initially set program information can be changed for a certain period after the sending device starts operating, and
If the program information for the next document can be specified while the calligraphic information of one document is being transmitted, the line can be used more efficiently, and the status of the receiving side can be determined in advance by the sending side, which will improve the management and operation of facsimile communications. Further improvement is brought about.

However, at present, a facsimile communication system having such a function has not yet been developed.

The present invention was developed in view of the above circumstances, and its contents will be explained in detail below with reference to illustrated embodiments.

FIG. 1 shows an example of a facsimile transmission device to which the method of the present invention is applied, in which 1 is a data reading section for a transmitted document, 2 is a read data processing section, 3 is a modem, 4 is a program information input section, and 5 is an input section. 4 is a program setting unit that stores program information from 4, and 6 is a status monitoring unit that monitors the status of each sequence of the transmitting device and controls the operations of the data reading unit 1 and the program input unit.

For convenience, it is assumed that the illustrated facsimile transmitting device is coupled to the receiving device through a conventional telephone line.

FIG. 2 shows a time chart of the transmitting side device.

First, when the power of the device is turned on, the contents of each part of the device are once cleared and the device becomes ready.

When this state is determined by the state monitoring section 6, the state monitoring section 6
A control signal DS is sent from.

Next, prior to starting the operation of the apparatus, the original to be transmitted is set in the data reading section, and the necessary program information is designated by operating the buttons or switches of the program input section 4.

As a result, the program information designated by the program manual section 4 is stored in the program set section 5.

At this time, the calligraphy information is not yet transferred from the data reading section 1 to the data processing section 2.

Next, a dial pulse RI is sent to the other party's terminal, and if the other party's receiving side normally receives this, the first response signal FR is returned from the other party's receiving side to the transmitter.

As a result, the program information in the program set section 5 is transmitted to the line L through the data processing section 2 and the modem 3.

When this program information is confirmed by the receiving end, the next response signal SR is returned to the transmitting device.

Since the sending of the control signal DS is stopped until this SR signal is detected by the status monitoring section 6, the transfer of program information from the program input section 4 to the program setting section 5 is prohibited.

At this time, the calligraphic information read by the data reading section 1 is supplied to the data processing section 2, where it is subjected to processing such as desired data compression, and then sent to the line L via the modem 3.

The status monitoring section 6 detects that this data is being transmitted, and the monitoring section 6 sends out a control signal DS, making it possible to transfer the program information from the input section 4 to the setting section 5 again.

In this way, the calligraphy information of the first manuscript is transferred, and if the next manuscript is to be transmitted, a control signal indicating this is transmitted and a response signal is received. Regardless of whether program information has changed,
Transmission of the program information stored in the program set section (if it has been changed, the changed program information; if it has not been changed, the previously set program information), reception of the response signal SR, and data transmission are each repeated. All you have to do is get it back.

Note that only when the program information has changed, the program information is sent and the response signal SR is received; if there is no change, the program information is not sent and the response signal SR is not received, and the calligraphic information data is transmitted. You may also do this.

When there are no more manuscripts to be transmitted, data is transmitted as conventionally done, and then a control signal indicating the end of all pages is transmitted, and the line is opened after a predetermined period of time.

Now, when the control signal DS is sent from the status monitoring section 6 and the program information becomes ready to be transferred from the input section 4 to the setting section 5, first, the power of the device is turned on, and as a result, the device becomes ready. This is the period from when the state is established until the dial pulse is sent to the receiving party.

Therefore, during this period, program information can be changed arbitrarily, and the contents of the program set section 5 are simply rewritten each time.

After that, the period from when the first and second response signals PR and SR are returned until the calligraphy information is actually sent out is as follows.
Since the set program information is being sent and the response confirmation period is still in progress, changes to the program information must be prohibited.

Next, after confirming the response of this program information, the control signal DS is sent out again during the sending period of calligraphy and drawing information, so it is possible to reset or change the program information during this period. The program information will be held in the program set section 5 until the next program information transmission period arrives.

As mentioned above, this operation is effective when changing the originally specified resolution, paper size, transmission speed, etc. for the next manuscript.

As described above, according to the facsimile communication method according to the present invention, during a certain period after the power is turned on until the actual transmission of calligraphic information starts, or during the transmission period of calligraphic information, the receiving side receives the necessary information. It is possible to reset or change program information, even if the receiving side is operated unattended.
The optimal state required on the receiving side can be continuously controlled from the transmitting side, making it possible to use the line efficiently.

Claims (1)

[Claims] 1. In a facsimile communication system in which program information such as the resolution and paper size required by the receiving side is transmitted prior to the transmission of written information from the transmitting side, the state of the operation sequence of the transmitting side is monitored and the program information is The program information is prohibited from being reset or changed during transmission and the response signal confirmation period, and the program information is allowed to be reset or changed during the period excluding the change prohibition period, and the program information is re-set or changed before the program information is sent. The set or changed program information is sent when the program information is sent during the operation sequence, and the program information that is reset or changed after the program information is sent is held until the next program information is sent.
