Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a facsimile apparatus connected to a common telephone line with a telephone.

(Prior Art) Conventionally, this type of facsimile apparatus is configured as shown in FIG. When the facsimile apparatus 2 is set to the automatic reception mode in order to receive data, when a ring signal 100 is input from the transmission side via the telephone line 1, the ring signal detection unit 4 detects this and controls the control unit. Inform 9 In response to this, the control unit 9 switches the CML relay 5 from the ringer generator 10 side of the telephone 3 to the network control unit 6 side. When the transmitting side calls the operator in such a state, the control section 9 of the receiving side facsimile apparatus 2 activates the alarm generating section 7 to generate an alarm sound from the sounding body 8 to call the operator. However, when an operation error occurs, this alarm sound is equivalent to the alarm sound generated from the sounding body 8 by detecting the operation error by the control unit 9 in the same manner as described above. However, there is a disadvantage that the volume level is extremely low and the operator is hardly aware. In addition, since the transmitting side does not return any signal from the receiving side at the time of calling the operator, there is a drawback that the receiver does not hear anything and the operation of the receiving side cannot be recognized.

(Problems to be Solved by the Invention) In a conventional facsimile apparatus, after a line is connected to the facsimile apparatus side, a ring tone of the telephone cannot be sounded when an operator calls from the transmission side. However, since an alarm sound is generated instead, the level of the alarm sound is small, and there is a problem that the receiving side operator is hard to notice. Also, since the transmitting side does not return any signal from the receiving side during the operator calling, there is a problem that it is not possible to confirm whether the calling operation is being performed on the receiving side. Therefore, the present invention eliminates the above disadvantages, and can generate a sufficiently large pseudo ring sound when an operator calls after a line is connected to the facsimile machine side.
It is another object of the present invention to provide a facsimile apparatus which can return a pseudo ringback tone to a calling side at this time.

According to the present invention, in a facsimile apparatus having an automatic reception mode, an audio signal detecting means for detecting an audio signal on a telephone line, and a transmitting side calling an operator. Pseudo ring tone generating means for generating a pseudo ring tone for notifying the above, pseudo ring back tone generating means for generating a pseudo ring back tone indicating that the pseudo ring tone generating means is operating, a transmitting side and a facsimile When a voice signal is detected by the voice signal detecting means in a state in which the communication is communicably connected to the telephone line, the pseudo ring tone generating means is activated to generate a pseudo ring tone and notify the receiving operator. Activating the pseudo ringback tone generating means to generate a pseudo ringback tone, Constituted by a control means for sending to the transmitting side via the telephone line in response to the side.

(Operation) In the facsimile apparatus of the present invention, the voice signal detecting means detects a voice signal in a state where the voice signal is connected to the transmitting side so that facsimile communication is possible, and notifies the control means. Thereby, the control means activates the pseudo ring tone generation means, generates a pseudo ring tone and notifies the receiving side operator, and activates the pseudo ring back tone generation means to generate the pseudo ring back tone to make a telephone call. Send on the line. As a result, the pseudo ring tone can be louder when the operator calls, and the pseudo ring back tone can be transmitted as a response signal to the calling side.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings by attaching the same reference numerals to the same parts as those of the conventional example. FIG. 1 is a block diagram showing the configuration of one embodiment of the facsimile apparatus of the present invention. 1 is a telephone line, 2 is a facsimile apparatus that shares the telephone line 1 with the telephone 3, 3 is a telephone, 4 is a ring signal detector that detects a ring signal transmitted via the telephone line 1, and 5 is a facsimile. CML relay for switching between device side and telephone side, 6 is a network control section for capturing or releasing a line, 7 is an alarm generating section for generating an alarm signal, 8 is a sounding body for raising an alarm or a pseudo ring tone, 9 is a line A control unit 11 for switching, capturing / releasing a line, generating an alarm, controlling the generation of a pseudo ring tone and a pseudo ring back tone, and the like, 11 is for setting the sound generator 8 to the alarm generation unit 7 side or the pseudo ring tone generation unit 12 side. Changeover switch,
12 is a pseudo ring tone generator that generates a pseudo ring tone, 13 is a pseudo ring back tone generator that generates a pseudo ring back tone, and 14 is voice identification that identifies whether or not the signal on the telephone line is a voice signal. Department.

Next, the operation of this embodiment will be described. For example, when the facsimile apparatus 2 is set to the automatic reception mode and the ring signal 100 is input via the telephone line 1, the ring signal detection section 4 detects this and notifies the control section 9.
In response to this, the control unit 9 switches the CML relay 5 from the telephone 3 to the network control unit 6 and connects the telephone line 1 to the facsimile machine 2. When the transmitting side calls the operator while the telephone line 1 is connected to the facsimile apparatus 2 side, the voice identification unit 14 detects a voice signal on the telephone line 1 and notifies the control unit 9 of this. In response to this, the control unit 9 activates the pseudo ring tone generation unit 12 and the pseudo ring back tone generation unit 13 and switches the changeover switch 11 to the pseudo ring tone generation unit 12 side. As a result, the pseudo ring tone is output from the pseudo ring tone generation unit 12 to the sounding body 8 via the changeover switch 11, and the pseudo ring tone having a sufficient volume is amplified from the sounding body 8. At the same time,
A pseudo ring-back tone is sent from the pseudo ring-back tone generator 13 to the telephone line 1 via the network controller 6,
Returned to sender. Here, the pseudo ring tone loudspeaked from the sounding body 8 has the same sound pressure level as the ring sound generated from the telephone 3. Also, when the operator is called during the facsimile communication, the voice discriminating unit 14 detects the voice signal on the telephone line and notifies the control unit 9 of the voice signal. While the tone is louder, a pseudo ringback tone is returned to the transmitting side.

FIG. 2 is a flowchart for explaining the operation of the control unit 9 at the time of automatic reception. In step 201, a ring signal detection wait is performed, and when a ring signal is detected twice,
At step 202, the CML relay 5 is switched to the facsimile machine 2 side to connect the line 1 to the facsimile machine 2 side. Thereafter, in step 203, it is determined whether or not the signal on the telephone line 1 is a voice signal. If so, the process proceeds to step 206; otherwise, the process proceeds to step 204. In step 206,
A pseudo ring tone sound is generated by the pseudo ring tone generation unit 12, and in step 207, a pseudo ring back tone is generated by the pseudo ring back tone generation unit 13.
At step 208, call control is performed. In step 204, facsimile communication is performed. In the meantime, it is determined in step 205 whether or not a voice signal is detected on the telephone line. If a voice signal is detected (in the case of a telephone call), the process proceeds to step 206. If not, it is determined in step 209 whether or not the communication has been completed. If not, the process returns to step 204; otherwise, the process proceeds to step 210. In step 210, the CML relay 5 is switched to the telephone 3 side, the telephone line 1 is connected to the facsimile apparatus 2, and the process is terminated.

As described above, according to the present embodiment, if an operator calls while the telephone line 1 is connected to the facsimile apparatus 2 side, a pseudo ring tone is uttered from the sounding body 8 at a necessary and sufficient sound pressure level. , The receiving operator can be immediately notified that there is an operator call. At the same time, the pseudo ringback tone is returned to the operator calling side (transmitting side), so that the calling side can confirm that the receiving side is currently calling the operator.

[Effects of the Invention] As described above, according to the facsimile apparatus of the present invention, when an operator calls after a line is connected to the facsimile apparatus side, a sufficiently large pseudo ring tone can be generated. Has the effect of returning a pseudo ringback tone.
