Abstract

PROBLEM TO BE SOLVED: To eliminate communication errors by erroneous operations by automatically switching a line to a facsimile reception state, then continuously performing facsimile communication and automatically disconnecting the line after it is ended at the time of disconnecting a telephone line. SOLUTION: When the call termination of the telephone line is voice, communication is performed with an opposite party. When it is ended and a receiver is placed, a control part 7 switches the line to a facsimile circuit 3 by a communication switching circuit 4 and turns it to the facsimile reception state. On the other hand, in the case that the opposite party is a facsimile, an operator presses a start button 5 and switches to the facsimile circuit 3. In the case that the receiver is placed without pressing the start button even though the opposite party is the facsimile, the control part 7 automatically switches the telephone line to the side of the facsimile circuit 3. In such a manner, at the time of disconnecting the telephone line, when the receiver is placed without switching to the facsimile reception state, by automatically attaining the facsimile reception state for fixed time, the communication errors are eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile receiving method, and more particularly to a facsimile receiving method for eliminating a facsimile communication error due to an erroneous operation in a facsimile apparatus with a telephone.

[0002]

2. Description of the Related Art When a facsimile is manually received by a facsimile apparatus with a telephone, a facsimile communication procedure sent from the other party is heard to determine whether or not the other party is a facsimile, and a facsimile reception is performed by pressing a start button. Switching to the state.

At present, a facsimile machine with a telephone has become widespread as a home facsimile machine, but most people who use the facsimile machine at home use a telephone line 1
It is common for books to switch between telephone and facsimile. In these cases, most people use it as a telephone rather than as a facsimile. For this reason,
Usually, the telephone is used as a telephone, and when the called party is a facsimile, it is common that the receiver manually presses a start button to switch to a facsimile reception state. Switching to facsimile reception in such a conventional facsimile apparatus with a telephone has been performed according to a processing procedure as shown in FIG.

[0004] First, when a telephone ringing bell rings (step S301), the receiver is picked up (step S3).
02), whether the other party's call is a human voice or a facsimile CNG signal (so-called "Peehyoro ...")
Is heard (step S3).
03). If a human voice is heard, the call is made as it is (step S304), and after the call ends, the receiver is put down and the line is disconnected (step S308).

On the other hand, in step S303, CNG
If a signal is heard, it is determined that the called party is a facsimile, and the start button is pressed to switch to a facsimile reception state (step S305), and communication is performed between the facsimile machines (step S307). Then, after the communication is completed, the line is automatically disconnected (step S308).

If the start button is not pressed in step S305 even though the CNG signal is heard in step S303, it is determined that a communication error has occurred after a lapse of a predetermined time (step S306).
The line is automatically disconnected (step S308).

As described above, in a conventional facsimile apparatus with a telephone, a facsimile is switched to a reception state by listening to a CNG signal sent from the other party and pressing a start button. In the case of such a method, it is necessary for the receiver to hear the sound to judge whether or not the facsimile is used. There is a possibility that the line may be cut off with the receiver unnoticed.

Therefore, in order to eliminate such a problem,
Conventionally, a method of automatically switching to a facsimile reception state has been proposed. For example, JP-A-7-226809
In the official gazette, when a CNG signal is sent from the other party,
A facsimile machine with a telephone that determines that the communication is facsimile communication by detecting this, makes an announcement such as "the other party is a facsimile", and automatically switches the telephone line to the facsimile circuit side is shown. I have.

[0009]

However, in the above conventional example, the CNG signal detecting means and the voice notifying means are indispensable, which complicates the circuit configuration and increases the cost. Also, in the case of a silent facsimile apparatus in which the other party's facsimile does not transmit a CNG signal, the line is not switched to the facsimile reception state, and unless the receiving side operator presses the start button to switch to the facsimile reception state, the facsimile is normally transmitted. There was a problem that communication was not possible.

In view of the above, the present invention has been made in view of the above-mentioned problems in the conventional facsimile receiving method. In a facsimile apparatus with a telephone, a facsimile communication error due to an erroneous operation is eliminated, and extra time such as retransmission is eliminated. It is an object of the present invention to provide a facsimile receiving method capable of eliminating unnecessary call charges.

[0011]

According to the first aspect of the present invention,
A facsimile receiving method for a facsimile machine with a telephone, wherein when a telephone line connected to an external line is disconnected, the line is automatically set if the handset is placed at least once without switching to the facsimile receiving state. After switching to the facsimile reception state, it is monitored for a certain time whether a facsimile communication procedure signal is sent from the other party.If a facsimile communication procedure signal is sent from the other party during this time, the line is disconnected. The facsimile communication is continuously performed without disconnection, and the line is automatically disconnected after the communication is completed.

According to a second aspect of the present invention, in the facsimile receiving method according to the first aspect, it is always monitored whether or not a ringer (calling bell signal) has been transmitted through a telephone line. The processing according to claim 1 is executed only for

According to the first aspect of the present invention, when the receiver is placed without being switched to the facsimile receiving state at least once, if the other party is a facsimile, the facsimile reception is automatically performed. , It is possible to eliminate a facsimile communication error due to an erroneous operation, and eliminate unnecessary labor such as retransmission, thereby reducing unnecessary call charges.

According to the second aspect of the present invention, only when the ringer is sent before picking up the handset,
That is, only when the other party receives a call,
Since the facsimile receiving method of the present invention can be effectively operated, the line can be immediately disconnected when a call is made from the user, and the call charge can be further reduced.

[0015]

Next, a specific example of an embodiment of a facsimile receiving method according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a facsimile apparatus with a telephone constructed by applying the method of the present invention. This facsimile machine with a telephone has a telephone line 1 connected to an outside line,
A telephone circuit 2, a facsimile circuit 3, a communication switching circuit 4 for switching between the telephone circuit 2 and the facsimile circuit 3,
A start button 5 for manually switching to facsimile reception, a ringer detection circuit 6 for detecting a ringer (a ringing bell signal) when an incoming call is received, CPU, R
The communication switching circuit 4 is connected to the telephone circuit 2 in a normal state. The ringer detection circuit 6 is used in a second embodiment described later.

Next, a first embodiment of the method of the present invention will be described with reference to the flowchart of FIG. In the flowchart of FIG. 2, a portion surrounded by a dotted line is a processing portion newly added in the method of the present invention, and other processing portions are the same as those of the flowchart of the conventional method (FIG. 4). Each process in the flowchart of FIG. 2 is realized by software in the control unit 7.

First, when there is an incoming call from an outside line via the telephone line 1 and the calling bell of the telephone circuit 2 rings (step S101), the operator on the receiving side picks up the receiver (step S102). It asks whether the other party's call is a human voice or a facsimile CNG signal (step S103). If the human voice is heard, the call is directly made (step S104). Then, when the telephone call ends and the receiver is put down (step S106), the control unit 7 shifts the processing to step S108, controls the communication switching circuit 4 to switch the line to the facsimile circuit 3, and sets the facsimile reception state. Set to.

On the other hand, in step S103, CNG
If the signal is heard, the receiving-side operator determines that the other party is a facsimile, and manually presses the start button 5 (step S105). As a result, the control unit 7 controls the communication switching circuit 4 to switch the line to the facsimile circuit 3 side, and performs communication between the facsimile machines (Step S).
110). Then, after the communication is completed, the line is automatically disconnected (step S111).

If the CNG signal is heard in step S103 and the receiver is left down without pressing the start button in step S105 (step S107), the control unit 7 immediately proceeds to the telephone line. Without disconnecting, the process proceeds to step S108, where the communication switching circuit 4 is controlled to switch the line to the facsimile circuit 3 side, and set to the facsimile reception state.

As described above, in the facsimile receiving method according to the present invention, when the receiver is put down after talking with the other party (step S106), or when the CNG signal is heard, the receiver is erroneously put down. For example, when the telephone line connected to the external line is disconnected and the receiver is put down without being switched to the facsimile receiving state at least once (step S107), the processing is all performed in step S108. Move to.

Then, in step S108, after automatically switching the line to the facsimile reception state, the control unit 7 monitors for a predetermined time whether a facsimile communication procedure signal is transmitted from the other party. That is, if the other party is a facsimile (step S109), a facsimile communication procedure signal is sent continuously from the other party's facsimile machine, so that facsimile communication is performed as it is (step S110), and after the communication is completed, Is automatically disconnected (step S111). If not, a predetermined period of time is counted, and the line is automatically disconnected after a timeout (step S).
No. 109).

Thus, in the method of the present invention, when the telephone line connected to the outside line is disconnected and the telephone set is placed at least once without switching to the facsimile reception state, the line is disconnected. After automatically switching to the facsimile reception state, it is monitored for a predetermined time whether a facsimile communication procedure signal is sent from the other party.

For this reason, if the other party is a facsimile, it is possible to automatically shift to the facsimile reception, and it is possible to eliminate a facsimile communication error due to an erroneous operation.

Further, even when the other party is a silent facsimile apparatus that does not transmit a CNG signal, the facsimile reception state can be automatically switched to the facsimile reception state when the receiver is put down. Facsimile communication can be performed.

Further, as is apparent from FIG. 1, the facsimile apparatus with a telephone constructed by applying the method of the present invention does not require any means for detecting a CNG signal or voice notification means. It can be simplified and the cost of the device can be reduced.

Next, a second embodiment of the facsimile receiving method according to the present invention will be described with reference to FIG.

In the case of the first embodiment, not only when a call is received from the other party but also when a call is made from one's own, the facsimile reception state is automatically set when the handset is placed after the call is finished. Will switch to. Therefore, in the second embodiment, the facsimile receiving method of the present invention works effectively only when a call is received from the other party by performing ringer (ringing signal) detection processing. It is. In addition, this second
In order to realize the embodiment, it is necessary to additionally provide the ringer detection circuit 6 shown in FIG.

In the case of the second embodiment, the ringer detection circuit 6 constantly monitors whether or not a call is received from the other party and the bell rings, ie, whether or not a ringer has arrived (step S201). If the handset is lifted without detecting the ringer (step S202), the control unit 7 determines that the call has been made. Then, the call is dialed to the other party (steps S204 and S205), and after the end of the call, the line is disconnected immediately when the receiver is put down (step S206).

On the other hand, when the ringer is detected by the ringer detection circuit 6 in step S201 and the receiver is lifted (step S203), the control unit 7
Is determined to have received a call from the other party, and thereafter, step S10 in the flowchart of FIG.
3 and the same processing operation as in the first embodiment is performed.

Therefore, according to the second embodiment, the facsimile receiving method of the present invention can be automatically switched only when a call is received from the other party so that the facsimile receiving method of the present invention works effectively.

[0032]

According to the first aspect of the present invention, when the telephone line connected to the outside line is disconnected, if the receiver is placed at least once without being switched to the facsimile reception state, if the other party is placed, If the side is a facsimile, it automatically transitions to the facsimile reception state and can perform facsimile communication. For this reason,
Facsimile communication errors due to erroneous operations can be eliminated, and unnecessary labor such as retransmission can be eliminated, thereby reducing unnecessary call charges.

Even if the other party is a silent facsimile apparatus that does not transmit a CNG signal, the facsimile reception state can be automatically switched to when the receiver is put down, so that the facsimile apparatus can operate normally regardless of the operation of the receiving operator. Facsimile communication can be performed.

Further, when a facsimile apparatus with a telephone is manufactured by applying the present invention, a CNG signal detecting means and a voice notifying means are not required, so that the circuit configuration can be simplified and the apparatus can be simplified. Cost can be reduced.

According to the second aspect of the present invention, the facsimile receiving method of the present invention can be effectively operated only when a call is received from the other party. For this reason,
When a call is made from the user, the line can be disconnected immediately after the call is completed, and the call charge can be further reduced.
