Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile communication device having a normal call function.

[0002]

2. Description of the Related Art Conventionally, a facsimile communication apparatus having an automatic call receiving function can immediately receive a facsimile communication request from a calling side to perform facsimile communication. It was not possible to receive a call request from a telephone or the like.

Therefore, conventionally, in a facsimile communication apparatus having a call function, even if a request for a facsimile communication or a call request is made from a calling side, these can be dealt with by an automatic call receiving function. Is desired.

As a means for realizing such a facsimile communication device, for example, a method based on voice detection has been proposed. This method, when there is a call request from the calling side, calls the voice of the calling party. It is detected and the function of the facsimile communication device is switched to the call function.

As another method, there is considered a method in which a facsimile communication apparatus of the auto dial system detects a calling signal transmitted when making a facsimile communication request. According to this method, the calling signal is used. By detecting the presence or absence of the call, it is possible to identify whether the calling side is making a facsimile communication request or a call request.

[0006]

However, the former method described above has a problem in that the conventional facsimile communication apparatus must be additionally provided with a voice detecting means, resulting in an increase in cost. Further, in the latter method of the related art, even if the calling side makes a facsimile communication request by the facsimile communication apparatus by the manual dial method, the called side facsimile communication apparatus cannot be identified.
There is a problem that it becomes impossible to respond to the facsimile communication request from the calling side.

The present invention is capable of handling both the call request and the facsimile communication request from the calling side, and also the facsimile communication request from the manual dial type facsimile communication device. It is an object of the present invention to provide a facsimile communication device having an incoming call function.

[0008]

In order to achieve the above object, the present invention calls a predetermined first time as a silent section after a telephone line connection with a calling side, and calls during the first time. Detecting means for detecting a calling signal requesting facsimile communication from the calling side, a voice registration section for registering a call calling message in advance, and after the first time has elapsed without detecting the calling signal by the detecting means. A voice message transmission control means for reading out a voice message registered in the voice registration section and transmitting it to a telephone line; and a facsimile communication procedure when a call signal is detected by the detecting means during the first time period. If a call signal is not detected by the detecting means, a second time for calling a call is set. If there is no call start instruction during the second time, a call is issued. It is provided with a control means for outputting a signal for starting the Shimiri communication procedure.

[0009]

According to the present invention, therefore, after the telephone line connection with the calling side is made, when the calling signal for requesting the facsimile communication is detected by the detecting means in the silent section formed during the first time, The control means outputs a signal for starting the facsimile communication procedure, whereby the facsimile communication can be performed in the automatic dial type facsimile communication device.

On the other hand, if the detection means does not detect a calling signal requesting facsimile communication in the silent section formed during the first time, the voice message control means reads the voice message registered in the voice registration section. While transmitting to the telephone line, the control means sets the second time, and the user on the called side gives a call start instruction during the second time, whereby the call with the caller can be performed. .

Further, when there is no call start instruction during the second time, the control means outputs a signal for starting the facsimile communication procedure, whereby the facsimile communication can be performed in the manual dial type facsimile communication device. it can.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a schematic functional block diagram showing an electrical configuration of a facsimile communication apparatus according to an embodiment of the present invention, FIG. 2 is a timing chart showing an incoming call operation in the facsimile communication apparatus, and FIG. 3 is the facsimile communication. It is a flowchart which shows the operation | movement at the time of an incoming call in a device.

In FIG. 1, the facsimile communication device 1 is provided with a line network control unit 2 connected to a telephone line. The line network control unit 2 is connected to an external telephone line and the facsimile communication device 1. In addition to the line control operation, the automatic call receiving function is provided for connecting the facsimile communication device 1 and the calling side to the telephone line in response to the dialing from the calling side as described later.

The line control unit 2 is connected to a call unit 4 which forms a call path with a telephone set on the other end of the line by which a handset 3 including a transmitter and a receiver is connected. The control unit 6 for performing automatic switching control between the telephone function and the facsimile communication function is connected via the modulation / demodulation unit 7. The modulation / demodulation unit 7 modulates / demodulates a carrier signal transmitted / received by the facsimile communication apparatus via the telephone line. That is, the image information related to the facsimile communication is modulated / demodulated via the modulator / demodulator 7.

On the other hand, between the network control section 2 and the control section 6, the types of various control signals transmitted from the calling side via the telephone line and their signal levels are detected. A signal level detecting unit 8 for identifying by is provided as a detecting means, and a control signal sent from the facsimile communication device 1 (called side) to a calling side is created in response to the output of the control section 6. The signal transmission unit 9 is interposed,
In addition, the line network control unit 2 and the control unit 6 are in a connected state via the line l1 in order to realize an automatic incoming call function described later.

The control unit 6 includes a voice storage unit 10 in which a voice message to be sent to the calling side is stored, and a timing for counting a first time limit T1 and a second time limit T2, which will be described later. The unit 11, a speaker 12 for audibly converting a ringing signal or a voice message, which will be described later, a reading unit 13 for optically reading an image of a document loaded in the facsimile communication apparatus 1, and a telephone line. A recording unit 14 for recording the image information received via the recording unit 14 and an operation unit 15 including a dial key and the like are connected in parallel to the control unit 6.

In the facsimile communication apparatus configured as described above, in the case where the calling side having the automatic dial type facsimile communication function makes a facsimile communication request to the facsimile communication apparatus 1 (called side), A description will be given based on the time chart of FIG.

At time t0, the calling side makes a dial call to the called side. On the called side, the line polarity is reversed by the automatic call receiving function of the line network control unit 2 in response to the dialing call from the calling side (time t1). This realizes a line connection between the calling side and the called side.

Then, in the line network controller 2, when the inversion of the line polarity is detected, a signal indicating this is given to the line l1.
Is immediately sent to the control unit 6 via the line, and the control unit 6 recognizes that the line connection with the calling side is completed based on the signal from the line l1, and the first unit set in the clock unit 11 Timing of the time limit T1 (for example, 5 seconds) is started.

The first time limit T1 is a section in which the signal level detecting section 8 detects whether a facsimile communication request calling signal (hereinafter referred to as a CNG signal) is transmitted from the calling side, and the section is silent. By setting the interval as C
The NG signal can be surely detected in a short time.

For example, when a voice signal such as a pseudo ringback tone is transmitted to the telephone line during the CNG signal detection period, the CNG signal transmitted from the calling side and the pseudo ringback tone transmitted from the called side, etc. There is a possibility that the CNG signal cannot be detected at the time of the collision. Therefore, in the present embodiment, the first time limit T1 is a silent section.

This CNG signal is a signal of the type sent when a facsimile communication request is made in an automatic dial type facsimile communication apparatus, and is 1100 Hz.
Is a signal in which a sounding state in which a calling tone (Calling Tone) is generated for 0.5 seconds and a silent state for 3 seconds are alternately repeated. In this case, since the CNG signal is transmitted from the calling side, the facsimile communication device detects this and starts the communication procedure for performing facsimile communication with the calling side.

At the start of facsimile communication, the called station identification signal (CED) is sent from the called side to the calling side.
Signal-Called Station Identification-Tonal) is sent.

This CED signal is a signal in which a sound of 2100 Hz continues for 2.6 seconds to 4 seconds, and the calling side has the CE signal.
By receiving the D signal, it is possible to recognize that facsimile communication with the called party is possible.

After the CED signal is transmitted from the called side, a non-standard device signal (NSF signal-Non-Sta) is sent.
ndard Facilities "0000100"), Called station identification signal (CSI signal-Colled Station Identification-
Binary "000 0010"), digital identification signal (DIS signal-Digital Identification Signal "00
0 0001 ") is sent to the calling side in this order, and thereafter the image information from the calling side is received.

The control signals are created in the signal transmitting section 9. That is, the CNG signal received by the line network control unit 2 is detected by the signal level detection unit 8, and a signal indicating this is output to the control unit 6. As a result, the control unit 6 outputs to the signal transmission unit 9 a signal instructing the creation of each of the control signals. In response to this, the signal sending unit 9 creates each control signal and sends it from the line network control unit 2 to the calling side via the telephone line.

Next, the case where the calling side makes a call request by a normal telephone will be described with reference to the time chart of FIG. 2 (b).

At time t0, the calling side picks up the handset for making a call and makes a dial call. At time t1, when the inversion of the line polarity is detected on the called side, as described above, the first time delay time is set. Timing of T1 is started, and the presence or absence of the CNG signal described above is detected.

In this case, since the calling side is making a call request, the CNG signal indicating the request for facsimile communication is not transmitted, and the CNG signal is detected by the signal level detecting section 8 during the first time limit T1. Is not detected. As a result, the control unit 6 starts the end time t2 of the first time limit time T1 and then sets the second time limit time T2 preset in the timer unit 11.
The timekeeping (for example, 15 seconds) is started, and the call procedure described later is started.

That is, from the time t2 to the end time t3 of the second time limit T2, the voice message previously stored in the voice recording unit 10 is audible by the speaker 12, and a similar voice message is transmitted through the telephone line. To the calling side via. For example, a message such as "Call is requested" is used as the voice message to be sounded by the speaker, and a message such as "Call is being requested" is sent to the calling side. I am trying to use.

As described above, by making the voice message acoustic, it is possible to make a call request to the called operator, and in response to this call request, the called operator makes a second call. When the call start instruction is given by pressing the call key of the operation unit 15 or by picking up the handset 3 and cutting off the hook switch (not shown) during the time limit T2, the control unit 6 causes the network control unit. A switching signal is output to the control network control unit 2 that switches the telephone line to the communication unit 4 side based on the switching signal, and the facsimile communication device 1
To enable communication. This allows the called operator to talk with the calling operator.

On the other hand, on the calling side, when dialing is performed, the called side sends the above-mentioned message after the first limited time T1 has elapsed since the line was connected. The calling operator can hear this message through the picked up handset, and accordingly the calling operator is making a call request to the called operator, etc. It is possible to confirm the processing status of the called side facsimile communication device, and to be relieved of unnecessary anxiety caused by no response.

On the other hand, when the called operator does not give a call start instruction such as picking up the handset 3 during the second time limit T2, the facsimile communication apparatus 1 concerned
In response to a control signal creation command from the control unit 6, the signal sending unit 9 creates the CED signal, and the line network control unit 2
To the calling side via the telephone line, and the above-mentioned facsimile communication procedure is started.

In this way, the facsimile communication procedure is started in order to deal with the case where the calling side makes a facsimile communication request by the facsimile communication apparatus of the manual dial system.

That is, the facsimile communication apparatus using the manual dialing method makes a dial call and sends a CE from the called side.
After confirming the reception of the D signal, the operator presses the transmission start key to start the facsimile communication procedure, and the CNG signal as described above is not transmitted. In view of the configuration, the facsimile communication device 1
Then, when the called side does not receive the call request during the second time limit T2, the facsimile communication procedure is immediately started so that the facsimile communication request by the manual dial method can be dealt with. .

Next, the receiving operation in the called side facsimile communication apparatus will be described with reference to the flow chart shown in FIG.

In step n1, when the line network control unit 2 detects that the line polarity has been reversed, the counting of the first time limit time T1 is started in step n2.

When the CNG signal is detected in step n3, the process proceeds to step n10, the CED signal is sent to the calling side, and the facsimile communication procedure is started. If no CNG signal is detected in step n3, step n4
Then, it is determined whether or not the first time limit T1 has elapsed. If the first time limit T1 has not elapsed, the process returns to step n3, and if it does, the process proceeds to step n5.

In step n5, the timing of the second time limit T2 is started. At step n6, the call calling message is audibly output from the speaker 12, and at step n7, the call calling message is sent to the calling side through the telephone line.

In step n8, it is determined whether or not the second time limit T2 has elapsed. If not, the process proceeds to step n9.

In step n9, the handset 3 is picked up and it is determined whether or not the hook switch is cut off. When the hook switch is cut off, that is, when the operator gives a call start instruction, a call with the caller is started,
If no call start instruction is given, the process returns to step n6.

At step n8, the second time limit T2
Is completed, the process proceeds to step n10, the CED signal is sent to the calling side, and the facsimile communication procedure is started.

As described above, in the facsimile communication apparatus of the present invention, even if the calling side requests either the facsimile communication request or the call request, these can be dealt with by the automatic receiving function, and the calling side Regardless of whether the facsimile communication request of (1) is an automatic dial system or a manual dial system, these can be dealt with by the automatic incoming call function, and the versatility is improved.

In this embodiment, the call calling message is sent in the call procedure (see FIG. 3).
Alternatively, an alarm sound or the like may be sent instead of this call calling message. In this case, it is desirable that the alarm sound be a different type of signal from the ringing sound before the line polarity is reversed. As a result, the distinction between the ringing tone before polarity reversal and the alarm tone becomes clear, and the operator on the calling side hears the alarm tone to confirm that the call request is made to the called side. be able to.

[0046]

As described above, according to the present invention, it is possible to realize an automatic call receiving function capable of responding to both a facsimile communication request and a call request on the calling side, and a facsimile communication apparatus using a manual dial method. As described above, even a communication device which does not send a calling signal requesting facsimile communication prior to making a facsimile communication request can be dealt with by the automatic incoming call function, and its versatility is improved.

Further, by detecting the ringing signal transmitted from the calling side in the silent section, the ringing signal can be detected reliably in a shorter time, and the facsimile communication can be performed even if the first time is set to a shorter time. The call can be made in a short time after the call is made in the case of a call request, and the waiting time of the operator on the calling side is shortened and the silence period is shortened. It is possible to reduce the anxiety felt by the operator on the side, and further, by sending a voice message after the silent time has elapsed, the anxiety held in the silent time can be removed.
