Description

DETAILED DESCRIPTION OF THE INVENTION (Objectives of the Invention) (Industrial Field of Application) The present invention relates to a facsimile apparatus having a function of specifying a terminal at the other end and responding to reception.

(Conventional Technique #g) As is well known, the demand for facsimile machines has been increasing in recent years because they can easily transmit image information written on paper through telephone lines.

One of the reasons for the increased demand for facsimile machines is that facsimile machines do not require complicated operations unlike other communication devices of this type.

An automatic reception function is known as a typical function that makes this complicated operation unnecessary.

When the receiving terminal receives an incoming call signal in response to a call from the transmitting terminal, it automatically connects to the telephone line.
Furthermore, it is a function to perform facsimile communication with the other party's terminal after exchanging facsimile procedure signals through the connected telephone line, which is extremely convenient as it allows receiving one-stroke signals without the need for human intervention. It is.

On the other hand, since this automatic reception function operates to receive and respond to incoming call requests from any terminal without specifying the other party's terminal, unnecessary or inconvenient signals are also recorded and ejected, resulting in paper This also had the disadvantage of encouraging waste.

One way to resolve this inconvenience is to cancel the automatic reception function if necessary and operate it manually, but this method lacks the original meaning (the operation is complicated and inconvenient). I had no choice but to do it.

One of the most effective methods for conventional facsimile machines devised to resolve this inconsistency was to utilize facsimile procedures to limit incoming or outgoing calls to only a specific recipient's terminal. .

In this method, a specific code is set in advance on both the sending and receiving terminals, this is incorporated into the facsimile procedure, the content is checked while sending and receiving, and communication is performed only when the specific codes match. It controls what is allowed.

In this regard, current facsimile procedures are standardized by international standards, and standard signals incorporating these specific codes have not been defined.

Therefore, in order to realize the above-mentioned functions within this restriction, the manufacturer of the facsimile machine must make settings to use non-standard signals permitted by the national WA standard.

For this reason, this method cannot be put to practical use because it is not possible to easily change the specific destination terminal for receiving or sending calls, and the user is forced to use only facsimile machines from the same manufacturer. was the current situation.

(Problem to be Solved by the Invention) As described above, in the above-mentioned conventional facsimile machine, a function for specifying the communication partner terminal is added to the automatic reception function due to restrictions on the specific code that should be incorporated into the facsimile procedure. However, while it is possible to enjoy the benefit of being able to automatically receive image signals without the need for human intervention, the ability to respond to incoming call requests from all other party's terminals and record the reception saves recording paper. There was a problem that it was inevitable to waste money.

The present invention has been made in view of the above-mentioned circumstances, and can perform the function of identifying the other party's terminal and responding to the reception without being limited to facsimile machines of the same manufacturer. It is an object of the present invention to provide a facsimile device that can reduce waste of recording paper due to recording and ejection of inconvenient image signals.

[Structure of the invention]

(Means for Solving the Problems) The facsimile device of the present invention provides a facsimile device that sends a predetermined message to the other party's terminal in order to transmit a PB@ number with prescribed content to the other party's terminal through the telephone line captured upon incoming call. An announcement transmitter that transmits an announcement, and a PB signal that receives a PB signal received from a terminal on the other end through an input operation according to the announcement, and detects whether or not the PB signal has a preset specified content. The present invention is characterized in that it includes a detecting section, and responds only to an incoming call request from the other party's terminal that arrives with a PB signal having the specified content.

(Function) In the facsimile device of the present invention, when a call is received, after capturing the telephone line, a specified PB signal is collected from the other party's terminal, and when the PB signal has a specified content set in advance, PB is a signal (corresponding to the conventional identification code) used to identify the other party's terminal that responds to the reception.
By using signals, it can be used regardless of the model or manufacturer of the facsimile machine.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a block diagram showing the overall configuration of a facsimile communication system according to the present invention, in which 1 is a transmitting side facsimile device (hereinafter abbreviated as transmitting side FAX), 2 is a transmitting side FAX
A telephone connected to AX1 is capable of transmitting a PB (button button) signal, 3 is a telephone line, and 4 is a receiving facsimile device (hereinafter abbreviated as receiving FAX).

Further, FIG. 2 is a block diagram showing the configuration of the receiving side FAX 4 as an example of a single configuration of the facsimile apparatus according to the present invention, in which the telephone 140, the incoming call detection section 41, the switching device 42
, 43, facsimile communication section 44, PB signal detection section 45
, an announcement sending section 46, and a control section 47.

The operation will be explained in detail below with reference to the flowchart of FIG.

First, when a transmission request occurs, the operator of the sending FAX 1 performs an input operation using the telephone 2 to call the receiving FAX 4.

A calling signal sent from the sending FAXI in response to this input operation arrives at the receiving FAX 4 through the telephone port 13.

At this time, in the receiving side FAX 4, the contact point of the switching device 42 is connected to the terminal a side, and the above-mentioned calling signal received through the telephone port 13 passes through the switching device 42 to the incoming call detection unit 41.
is input.

Here, the incoming call detection section 41 detects whether or not there is an incoming call while monitoring the above-mentioned calling signal (step 100).

The control unit 47 that monitors this detection result immediately captures the corresponding telephone port 13 when an incoming call is detected (Step 101), and at the same time, the switching device 4
Switch the connection of contact 2 to the terminal side.

At this time, since the contact of the switch 43 is connected to the terminal d side, as a result of the above connection control, the telephone line 3 is connected to the P
The B signal detection section 45 and the announcement transmission section 46 are connected.

After establishing such a connection mode, the control unit 47 sends an announcement to the sending unit 4, for example, “This facsimile machine starts communication by a predetermined button signal.”
6 to the telephone line 3 several times at intervals (step 102), thereby prompting the sending side FAX 1 to input a specified PB signal.

When a PB signal is input by key operation on the telephone 2 at the transmitting FAX 1 according to this announcement, this PB signal is sent to the telephone line 3 in the same way as a ringing signal, and after being received by the receiving FAX 4, it is switched to N421. 43 to the PB signal detection unit 45 (step 103)
.

Thereby, the PB signal detection section 45 detects the PB signal and notifies the control section 47 of the detection result.

Next, the control unit 47 searches for whether or not the received PB signal has a predetermined content based on the detection result of the PB signal detection unit 45 (step 104).
If the content is as specified, the contact of the switch 43 is switched to the terminal C side, and then the facsimile communication section 44 starts transmitting and receiving facsimile procedure signals through the telephone line 3 (step 105).

Along with the communication of this facsimile procedure signal, the sending side FAX
1, the operator of the sending FAX 1 confirms that the receiving FAX 4 has started the facsimile signal procedure by the CED signal sent through the telephone 2, and operates the send button to start transmitting the facsimile procedure signal and image signal. .

The receiving side FAX 4 receives this transmitted image signal (
Step 106).

Thereafter, the received image signal is stored in a storage section (not shown), and is subjected to processing such as being recorded and discharged from the recording section as necessary.

By the way, the PB received in the judgment at step 104
If it is determined that the signal does not have a predetermined content, the control unit 47 promptly disconnects the line (step 107) and forcibly discards the previously accepted call.

With such control, the facsimile apparatus of the present invention allows only reception responses to and from a specific partner terminal whose PB signal satisfies the specified content, thereby preventing unnecessary or inconvenient image signals from being recorded and discharged. With the regulation, it becomes possible to minimize the waste of recording paper.

In order to identify the other party's terminal that is permitted to receive a response, instead of using a facsimile procedure that includes a specific code as in the past, PB signals with specified content are collected from the other party's terminal. If the terminal has this PB low signal transmission function, the scope of application can be extended beyond the boundaries of manufacturers and models, that is, to general facsimile machines.

In addition, if it is possible to set this point arbitrarily on each facsimile machine with a specified PB low signal, even if this PB low signal becomes known to another person, by changing the setting, an outsider can prevent communications. It also makes it easier to prevent abuse.

〔Effect of the invention〕

As explained above, according to the facsimile apparatus of the present invention, an incoming call is accepted and only when the PB low signal specified content is later collected from the other party's terminal, a reception response is received in response to an incoming call request from the other party's terminal. As a result, even if the other party's terminal is a general facsimile machine, a function can be added to identify it and respond to reception, thereby minimizing the waste of recording paper while restricting the recording of reception of unnecessary or inconvenient image signals. It has the excellent advantage of being able to be kept to a minimum.
