Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine having a response voice synthesis circuit capable of responding by voice.

2. Description of the Related Art Conventionally, a facsimile apparatus has been provided with a voice synthesis circuit,
When a call from the calling side arrives, first a voice response, for example, "This is XX" is made, and then a CED signal (callee identification signal) is issued. Things are known.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, the conventional facsimile apparatus is configured to always make a voice response regardless of whether the calling side is automatically calling or manually calling. However, there is a problem that communication time is wasted only for the time required for voice response because voice response is not required.

Therefore, a technique is known in which the CNG signal transmitted in the case of automatic calling is used to detect the CNG signal while the voice response is being performed, and the CED signal is immediately issued when the CNG signal is detected. (See Japanese Patent Laid-Open No. 60-241367). However, even with such a configuration, it is difficult to detect the CNG signal during the voice response. Since the voice is always sent to the calling side, the calling side may detect the voice as a CED signal. Since the voice is always sent to the calling side, there is an inconvenience that the calling side operator feels uneasy when the calling side monitors.

The present invention has been made in view of the above-mentioned problems, and when an automatic call is received, it does not give a voice response and immediately CE.
It is an object of the present invention to provide a facsimile machine capable of issuing a D signal.

Means for Solving the Problems The present invention, in order to solve the above-mentioned problems, means for detecting an incoming call from a calling side, and a CNG signal for detecting a CNG signal after the incoming call is detected by this means. Signal detection means,
When the CNG signal detecting means detects the CNG signal, the facsimile signal is transmitted immediately when the CNG signal detecting means detects the CNG signal, and when the CNG signal detecting means does not detect the CNG signal within a predetermined time. And a control unit for causing the voice transmitting unit to transmit a voice and then transmitting a facsimile signal.

With the above-described configuration, the present invention can reliably detect the CNG signal that is sent when the calling side makes an automatic call. Therefore, if the CNG signal is detected, the CED signal is immediately sent and the normal CED signal is sent. If the calling side can make a manual call (if the CNG signal cannot be detected even after the lapse of a predetermined time after receiving the call), the procedure can be transferred to the facsimile procedure after making a voice response. .

Embodiments Embodiments of the present invention will be described below with reference to the drawings. First
FIG. 1 is a block diagram showing an embodiment of the present invention, in which 1 is a facsimile machine, 2 is a telephone, and 3 is a communication line. The facsimile apparatus 1 includes a reading circuit 4, a recording circuit 5, a modem 6 connected to these, a response voice synthesis circuit 7, and a control circuit 8.
And so on. The modem 6 and the response voice synthesis circuit 7 are connected to the communication circuit 3 through the changeover switch 9 and the line transformer 10. The changeover switch 9 is connected to the position where the communication line is connected to the modem 6 and the response voice synthesis circuit 7. It is possible to switch to the position to turn on. The control circuit 8 has a function of controlling the modem 6 and the response voice synthesizing circuit 7 as in the case of a normal facsimile machine, and further determines whether to detect a CNG signal sent from the calling side via the communication line 3. It also comprises a circuit and control means for controlling the switching means in response to a signal from the determination circuit.

Next, the response operation at the time of reception in the above apparatus will be described with reference to the operation flow chart of FIG. 2 and the signal response charts shown in FIG. 3 and FIG. Normally, the changeover switch 9 shown in FIG. 1 is in a position where the communication circuit 3 is connected to the modem 6.

(1) In the case of automatic calling As shown in FIG. 3, the calling side issues a CNG signal indicating automatic calling after a predetermined time has elapsed from the calling. On the other hand, on the called side, the decision circuit detects the CNG signal after the call is received (step 2 in FIG. 2), and immediately after the detection, the CED signal is issued (step 3) and the normal facsimile procedure is started. Therefore, in this case, the response voice synthesis circuit 7
Remains unconnected to the communication circuit 3 and does not make a voice response, so that the CED signal is promptly transmitted accordingly.

(2) Manual calling As shown in FIG. 4, the CNG signal is not generated after the calling side calls. Therefore, in FIG. 2, the judgment circuit on the called side cannot detect the CNG signal (step 2), and after a predetermined time elapses, the changeover switch 9 is switched to connect the response voice synthesis circuit 7 to the communication line 3 (step 2). 4). Then, in step 5, the response voice synthesis circuit 7 makes a voice response, for example, "This is XX". After the end of the response, the changeover switch 9 is changed over to connect the modem 6 to the communication line 3 (step 6), and the CED signal is transmitted (step 3). After that, the procedure shifts to a normal facsimile procedure.

EFFECTS OF THE INVENTION As is clear from the above description, according to the present invention, when a CNG signal is detected within a predetermined time after an incoming call, the voice communication is immediately started without sending a voice. Therefore, unnecessary voice response is omitted. In addition to enabling prompt communication, the calling side operator does not feel uneasy even if the calling side monitors. Further, since the voice is not transmitted until the predetermined time elapses, the CNG signal can be reliably detected, and the calling side does not erroneously detect the voice as the CED signal.
