Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a destination identification device (hereinafter simply referred to as an ID identification device) for a facsimile machine having an automatic reception function.
In particular, the present invention relates to a device that automatically receives only data from a desired sender by identifying an ID code sent from the sender.

Generally, in facsimile communication, a transmitting station that has information to be transmitted calls a desired transmitting station and performs communication.

By the way, if the facsimile machine on the receiving side that receives a call is in the automatic reception state, the reception operation for this call is passive, and as long as the line is open, it will answer and receive any call. I had gone through the motions. In other words, the receiving station had no choice.

Therefore, when a certain receiving station needs to send urgent documents, other stations call the receiving station before the specific station and send a large amount of documents. If such a request is made, the emergency document cannot be received until after the large amount of documents have been received, resulting in a delay in receiving the emergency document. Note that there is also a method of interrupting the reception to stop the transmission/reception operation during the reception, but in order to perform the desired reception thereafter, it is necessary to make appropriate contact with the two transmitting stations mentioned above. procedures were necessary.

This invention has been made in view of the above-mentioned circumstances, and is a facsimile machine that can receive only data from a desired sender by identifying the ID code sent from the sender at the time of reception. An object of the present invention is to provide an ID identification device for controlling.

In other words, this invention stores in memory the code of one person from whom one wishes to receive by using a means such as a numeric keypad or a mark sheet, and also stores the ID code sent from the other party at the time of injury. Once stored in the memory, these two ID codes are compared, and only when these codes match, the facsimile machine is driven to receive a document.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An ID identification device according to the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows an example of the configuration of a facsimile machine equipped with a separate IDR device according to the present invention.

In this figure, the facsimile device 10 includes a transmission scanning section 12 which is a means for reading a document to be transmitted, a reception scanning section 11 which records a document transmitted from the outside, and these operations, especially scanning control. Scanning control unit 1.3, 1
It has a transceiver type configuration with 4 and 4 respectively.

First, the transmission operation of the facsimile machine 10 will be briefly explained. The information read by the transmission scanning section 12 under the control of the scanning control section 14 is first sent to the band compression/expansion section (hereinafter simply referred to as "companding section") 15 where appropriate signal processing is performed and unnecessary redundancy is eliminated. is reduced, the band is compressed, and the signal is sent to the transmission control unit 16. The transmission control section 16 controls the state and communication between devices in response to the control operations of the network control section 18, which will be described later.
It manages the overall operation. The band-compressed signal is sent to the modulation/demodulation section 17 via the transmission control section 16, subjected to appropriate modulation, and further outputted via the network control section 18. This network control unit 18 controls connections with other facsimile machines tA1 to A6, etc.

Next, the receiving operation of the facsimile machine 10 will be explained.

The received data received via the network control section 18 is sent to the modulation/demodulation section 17 and subjected to appropriate demodulation, and then sent to the companding section 15 via the transmission control section 16. Appropriate signal processing is performed in the compression section 15 to decode the band line data into original video data, and then the video data is sent to the reception scanning section 11 under the control of the scanning control section 16 for predetermined recording operations. will be carried out.

The facsimile machine 10, which has the same components as the above-mentioned normal equipment, is equipped with an iD identification device 20 according to the present invention, and includes a controller 21, memories 22, 2
3 and a comparator 24. In this embodiment circuit, the controller 21 is connected to the scanning control section 14, and a mark sheet (not shown) marked with the ID code of the desired communication partner, which has been input to the transmission scanning section 12, is transferred to the transmission scanning section 12 by an appropriate switch ( It has a function of reading a code based on input (not shown) and storing the read code in the memory 22. Further, the controller 21 includes the network control unit 1
8, and has a function of inputting the ID code sent from the outside at the time of reception via the network control unit 18 and storing it in the memory 26. Sarasuko, the controller 21 is a memo! It has a function of driving a comparison unit 24 that compares the contents stored in J22.23,
Along with the memories 22 and 23, it is also connected to a comparator 24.

Next, the comparison unit 24 is connected so that the contents of the memories 22 and 26 are input, and compares the stored contents, and if they match, outputs a signal to the network control unit 18. It has a function.

The facsimile machine 10 equipped with the IDR-specific device 20 having the configuration and functions described above is connected to other facsimile machines A1 to A6, . . . via an appropriate exchange machine CH.

Next, the overall operation of the above embodiment will be explained.

First, the operator of the receiving station, that is, the facsimile machine 1
When the operator on the 0 side needs to receive data only from a specific transmitting station (assumed to be the A1 station in this case), the operator sends a mark sheet containing the code of the specific transmitting station to the transmitting scanner 12. , and operate the switch means (not shown) for reading the code mentioned above. As a result, the controller 21 sends a signal to the scan control section 14, and the scan control section 14 further drives the transmission scanning section 12 to scan the mark sheet on which the ID code of the A1 station is written and read its contents. . The read contents, ie, the ID code of the A1 station, are stored in the memory 22 via the controller 21.

After the above operations are completed, the operator of the transmitting station A1 makes a call to the facsimile machine 100 and transmits the pre-assigned ID code of the own station via the exchange CH. The transmission is detected by the network control section 18 of the facsimile machine 10, and the ID code transmitted from the A1 station is sent to the controller 21, and the controller 21 stores the code in the memory 26.

After the above operations, the controller 21 sends a signal to the comparator 24, and in accordance with this, the comparator 24 sends a signal to the memory 22,
Compare the contents stored in 23. When this matches,
The comparator 24 issues a signal to the network controller 18, thereby completing the transmitting station confirmation work.

In response to the above operations, the network control section 18 holds the line as in the normal case, receives the data transmitted from the A1 station, and changes the received data to the aLJj1 section 17 and the transmission control section 16.
, the band compression/expansion unit 15 appropriately processes the data, and the scan control unit 16 and reception scanning unit 11 perform predetermined recording.

Next, when there is a transmission from a third party's facsimile machine A2, A3..., the code stored in the memory 22 and the facsimile machine (ftA2, A6... Since the codes do not match, the comparison unit 24 does not output a signal to the network control unit 18. Therefore, the network control unit 18 disconnects the established line for further confirmation, and then starts the next line. This will be necessary for reception.

For example, if it becomes necessary to have an urgent document sent from A1 station while receiving from A2 station 1, etc., interrupt the reception to stop the reception and restart the sending/receiving operation. After stopping, A is stored in the memory 22 as described above.
All you have to do is rub the area to write the ID code of one station. The facsimile machine 1o that has had the ID code of the A1 station convoluted with it will only receive messages from the A1 station from now on, so when contacting the two stations mentioned above, it will receive emergency documents from the A1 station. Do this after recording (just rub it.

Further, in the above embodiment, a mark sheet is used as a method for storing the code of the other party in the memory 22, but the method may be any other method, such as a numeric keypad provided in a facsimile machine, etc. You may also use

Further, in the above embodiments, the present invention is applied to a facsimile machine for both sending and receiving purposes, but it goes without saying that the present invention may be applied to a facsimile machine for receiving only. Furthermore, in the above embodiment, I
Although the D identification device 2o is configured independently of the facsimile device 10, it may be configured such that the transmission control section 16 or the network control section 18, for example, has a similar function.

As explained above, according to the ID identification device according to the present invention, when receiving data, the facsimile machine is controlled so as to receive only data from a desired sender.
As a result, excellent facsimile communication can be realized.
