Abstract

PROBLEM TO BE SOLVED: To start facsimile receiving operation even without always detecting a CNG signal during automatic recording operation when facsimile transmission is performed on the side of party after a business message is left and further, to prevent the occurrence of malfunction caused by the erroneous detection of voice as the CNG signal. SOLUTION: When the recording of business message ICM is started (S4) after a response message OGM is sent out (YES in S3), the detecting operation of the CNG signal is interrupted and after the end of the business message ICM (S7), the detecting operation of the CNG signal is restarted (S8 and S9). When the CNG signal is detected, the facsimile receiving operation is started. Thus, the voice is not erroneously detected as the CNG signal and even in the case of facsimile transmission after the recording of the business message ICM, the facsimile is received.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having an answering machine function.

[0002]

2. Description of the Related Art Conventionally, in a facsimile apparatus of this type, when an incoming call is received in response to a call from a destination, a response message (OGM: Out Going Message) is sent out, and a voice message from the destination is used. Message (ICM:
Incoming Message) is recorded in the absence mode, and in this mode, if the other party performs facsimile transmission after leaving a business message, there is a facsimile reception operation. In order to perform such a facsimile receiving operation, it is necessary to always detect a CNG (Calling Tone) signal transmitted from the other party at a predetermined period even during the absence recording operation.

[0003]

However, in the conventional facsimile apparatus as described above, when a CNG signal is constantly detected during an answering machine operation, the voice of the message may be erroneously detected as a CNG signal and malfunction may occur. There is. In some cases, the CNG signal is detected only for a certain period of time after the start of the absence recording.
If a facsimile is sent after recording the message, the facsimile cannot be received.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. Even if a CNG signal from the other party is not always detected during an absence recording operation, a message message can be obtained in the absence recording operation. To provide a facsimile apparatus with an automatic voice recording function that can enter a facsimile receiving operation when the other party performs facsimile transmission after leaving a voice message, and does not detect a voice as a CNG signal and cause a malfunction. And

[0005]

In order to achieve the above object, according to the present invention, an incoming call is received in response to an outgoing call from a destination, and a response message is sent out. In a facsimile apparatus having an automatic voicemail recording function, a CNG signal is detected from the time when a response message is sent until the start of receiving a business message, and the business message is received and the CNG signal is detected during the recording. Signal detection means for interrupting the operation and resuming the CNG signal detection operation after the end of the message, and performing the detection operation for a predetermined time, and facsimile control means for entering a facsimile reception operation when the signal detection means detects the CNG signal. And line control means for releasing a line when a predetermined time has elapsed without detecting a CNG signal after the end of the message. .

In the above configuration, the CNG signal is detected by the signal detecting means from the time the response message is sent until the start of receiving the message, and the CNG signal detecting operation is interrupted during the recording of the message. After the end of the message, the detection operation of the CNG signal is restarted and the detection operation is performed for a predetermined time. In any case, the facsimile reception operation is started when the CNG signal is detected. Further, when a predetermined time has elapsed without detecting the CNG signal after the end of the message, the line is released. As described above, during the recording of the message, the CNG signal detection operation is not performed, and the CNG signal detection operation is restarted after the completion of the message, so that the voice is not erroneously detected as the CNG signal. The facsimile can also be received when a facsimile is transmitted after the message is put.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a facsimile apparatus with an answering machine. The facsimile apparatus 1 is connected to the telephone line 2 and has a built-in (or external connection) telephone 3 having a voice mail recording function, and includes a telephone 4 and a CPU 4 for controlling the facsimile operation. The telephone 3 has a hook relay 5, a speech network 6,
It comprises a ringer 7, a handset 8, a ringer speaker 9, and the like. In addition, a microphone 10 for inputting an answering message (OGM) of voicemail recording and a speaker 11 for listening to a message message (ICM) voicemail are provided by a modem for demodulating analog signals and digital signals. 12 is connected to the CPU 4. This modem 12 is connected to the telephone line 2 via the hook relay 5. The CPU 4 has a memory 13 including a RAM for storing a response message and a message and a ROM for storing various programs, a key input unit 14 including a switch for inputting various commands, and a document image to be transmitted by facsimile. A CCD 15 to be read, a motor 16 for transporting an original or a recording sheet, a thermal head 17 for recording a facsimile reception image, and the like are connected. Power is supplied from the power supply circuit 18 to each unit.

The CPU 4 controls a facsimile operation according to the facsimile protocol, and executes a process based on an absence recording mode operation program and the like stored in the memory 13 in response to various command signals from an external device through the telephone line 2. . That is, in the absence recording mode, the CPU 4 receives an incoming call in response to a call from the other party, sends a response message, and then records the message from the other party in the memory 13. Further, after entering the answering machine recording mode, the CPU 4 controls an operation of detecting a CNG signal transmitted at the time of facsimile transmission from the destination apparatus (signal detecting means). CNG signal detection is performed for a predetermined time after the response message is sent until the start of reception of the message and after the completion of the message. The CNG signal is detected during the recording of the message and the recording of the message. I try to suspend. The CPU 4 enters a facsimile receiving operation when a CNG signal is detected (facsimile control means), and releases a line when a predetermined time has elapsed without detecting a CNG signal after the end of the message (line control means).

FIG. 2 is a flow chart showing the operation procedure of the facsimile apparatus 1 in the absence recording mode. When an incoming call automatically goes off-hook, a response message (O
GM) is started (S1), and it is checked whether a CNG signal is received (S2). If a CNG signal has been received (YES in S2), the process enters the facsimile protocol, and facsimile reception is performed (S10). If no CNG signal is received (S2
After waiting for the end of the OGM (YES in S3), recording of a business message (ICM) from the other party is started (S4). Thereafter, until a predetermined timer time elapses (NO in S5), it is checked whether or not a CNG signal has been received (S5).
6) When the timer time elapses (YES in S5), I
It is checked whether the CM has been completed (S7). When the ICM is completed, the second timer is started, and it is checked whether or not a CNG signal has been received until the timer expires (S8) (S9). When the timer expires (S
(YES at 8), release the line (off-hook) (S1)
1). In steps S6 and S9, when a CNG signal is received,
The process enters the FAX protocol (S10).

The present embodiment is characterized in that the detection of the reception of the CNG signal is interrupted during the recording of the message ICM started in S4, but the CNG signal is not detected until the timer time elapses in S5 and S6. The reason for checking for the presence or absence of reception is as follows. That is,
Although the CNG signal reception presence / absence detection period is defined by the communication procedure, if the CNG signal reception presence / absence detection is interrupted immediately after the end of the OGM, the OGM reproduction period alone may be less than the specified period. Because.
Therefore, the interruption of the CNG signal detection is strictly based on S5.
Recording of the business message ICM excluding the timer time.

According to the facsimile apparatus 1 of the present embodiment, the detection of the CNG signal is interrupted during the recording of the message ICM, the detection of the CNG signal is resumed after the completion of the message ICM, and the detection is performed only for a predetermined time. Because
Compared to one that constantly detects CNG signals from the other party during answering machine operation, it does not cause malfunction by erroneously detecting voice as CNG signal, and after leaving a message message during answering machine operation The facsimile reception operation can be started even when the other party has performed facsimile transmission.

[0012]

As described above, according to the facsimile apparatus with the automatic recording function according to the first aspect of the present invention, the operation of detecting the CNG signal is interrupted during the recording of the message, and the CNG signal is output after the completion of the message. The detection operation is restarted. Therefore, in order to receive a facsimile when a facsimile is transmitted after a business message, if the CNG signal is always detected during the recording of the business message, the voice may be erroneously detected as a CNG signal during the recording. However, such malfunctions are reduced. Also, after starting recording of the business message, CNG only for a certain period of time
In the case of detecting a signal, if the message is transmitted by facsimile after the end of the message, it cannot be received, but such a problem is also solved.
