Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone number of a calling party when a calling side has a call purpose when a facsimile machine capable of automatic reception is waiting in an automatic receiving mode. The present invention relates to a facsimile device capable of confirming a call on the called side.

2. Description of the Related Art In recent years, the user base of facsimiles has rapidly spread to shops and homes. When using a facsimile, many methods have been adopted in which the existing line is switched and used instead of providing a dedicated line for the facsimile. In this case, when a facsimile machine capable of automatic reception is in standby in the automatic reception mode, if there is a call from the calling party for the purpose of communication, the called party continues the facsimile transmission control procedure and the facsimile signal does not arrive. At that time, the line was put on hold for a certain period of time and then returned to the standby state.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, in the conventional facsimile communication method as described above, when a call is made from the calling side for the purpose of communication while waiting in the automatic reception mode, the called side has a facsimile transmission control procedure. It is still returning signals. For this reason, the calling party was inconvenient because he did not know his intention and that the called party also received an incoming call for the purpose of calling.

The present invention solves the above-mentioned drawbacks of the conventional facsimile apparatus, and provides a facsimile apparatus capable of confirming the telephone number of a caller intended for a call even when the facsimile apparatus is on standby in the automatic reception mode. The purpose is to do.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention detects a calling signal from a calling side and a switch for connecting a line to a facsimile machine side by an output from the detecting means. Means, an announcement means for returning a voice message to the calling side before the start of the facsimile transmission procedure after switching the line by the switching means, and a telephone number information sent from the calling side in response to the voice message. Detection means, storage means for storing the telephone number information detected by the detection means, telephone number information stored in the storage means, and whether or not the telephone number information is appropriate for the calling side. It is provided with a structure of response means for confirming.

When the control section receives the call signal from the calling side, the control section operates the switching means to switch the line connection to the facsimile machine side. After this, when a telephone number is sent by a selection signal such as an MF (multi frequency code) signal or a DP (dial pulse) signal, the telephone number indicated by the selection signal is temporarily stored in the storage means. At the same time, the caller is asked to confirm whether the telephone number is appropriate.

Embodiment FIG. 1 is a block diagram showing a facsimile machine to which an embodiment of the present invention is applied.

This facsimile machine is connected to a line via a line connection terminal 1 and a loop detection circuit 2 for detecting the line capture status.
And the line transformer 4 through the loop detection circuit 2
Alternatively, it has a switching device 3 for switching connection to any one of the telephones 5.

The line transformer 4 is branched and connected to the voice announcement circuit 6 and the buffer circuit 7. The voice announcement circuit 6 is activated in the automatic reception mode when a predetermined signal is input, and sends a voice message having predetermined contents to the circuit via the line transformer 4. Further, the buffer circuit 7 takes in a facsimile signal, a facsimile control signal, an MF tone, etc. from the line via the line transformer 4. A high speed modem circuit 8, a 300 baud detecting circuit 9 and an MF tone detecting circuit 10 are connected to the buffer circuit 7.
The high-speed modem circuit 8 takes out the facsimile signal from the buffer circuit 7, demodulates it, and sends the demodulated facsimile signal to the recording unit 11 as a writing means. 300 baud detection circuit 9
Detects the 300 baud facsimile control signal input to the buffer circuit 7. The MF tone detection circuit 10 detects telephone number information (MF signal).

Further, a ringing signal detection circuit 12 is provided in the circuit on the side of the telephone 5 with respect to the switching machine 3, and this ringing signal detection circuit 12 is provided.
Detects a calling signal sent through the circuit and the switch 3.

A control unit 13 is connected to the loop detection circuit 2, 300 baud detection circuit 9, MF tone detection circuit 10, and ringing signal detection circuit 12, and a detection signal is input to the control unit 13 from each circuit. ing. This control unit 13 has a line switching relay 1
4, incoming call lamp 15 as a notification means, print switch 1
6, memory circuit 17, indicator 18 as a notation means and recording unit 1
1 is connected, and the control unit 13 controls the operation of this device.

The line switching relay 14 is controlled by a signal from the control unit 13 to switch the contact of the switching device 3 to operate. The incoming call lamp 15 lights up when the control unit 13 receives a signal from the other party for the purpose of talking. When the print switch 16 is actuated, the control unit 13 takes out the stored data (telephone number information) from the memory circuit 17 and transfers it to the recording unit 11, and the data is printed out from the recording unit 11 based on the transferred data. It has become so. The memory circuit 17 stores the telephone number information of the MF tone sent by the calling side. The display unit 18 displays the telephone number information retrieved from the memory circuit 17 by the control unit 13.

A method of confirming the other party's telephone number of the facsimile apparatus configured as described above will be described.

Now, when the facsimile machine is waiting in the automatic reception mode, the calling signal (16 Hz) is received from the exchange by the dial operation on the calling side, and the calling signal detection circuit 12 and the control section.
It is detected by 13 and becomes the facsimile reception mode,
The line switching relay 14 operates to switch the switching device 3, and the facsimile device and the line are connected. A voice message that has been registered in advance when activated in the automatic reception mode (for example, "This is receiving a fax. If you are sending a fax, hear a beeping sound before sending. When you hear the sound, and when it stops, dial your phone number so please dial. ").

In this case, when the other party's telephone number arrives from the other party in response to the voice message, the MF tone detection circuit 10 detects this telephone number information. This telephone number information is stored in the memory circuit 17 via the control unit 13.

At the same time, the facsimile transmission procedure is stopped, and an operation for checking whether or not the telephone number is properly detected is entered. That is, the corresponding number voice is extracted from the number voice registered in advance in the voice announcement circuit 6 corresponding to the number information on the basis of the number information detected by the MF tone detection circuit 10, and is returned to the other party. Ask the other party to confirm whether it is appropriate. When the confirmation is obtained, the incoming call lamp 15 is turned on, the switching device 3 is switched, the line is connected to the telephone 5 side, and the standby state is restored.

On the other hand, when the telephone number information does not arrive for the voice message sent by the voice announcement circuit 6, the facsimile transmission is performed in a predetermined procedure. Then, the buffer circuit 7
When the signal output from is a control signal used in the facsimile transmission control procedure, this signal is detected by the 300-baud detection circuit 9 as digital data and passed to the control unit 13. Then, the facsimile machine operates in accordance with a facsimile transmission control procedure, and when a facsimile image signal is input, the facsimile image signal is sent to the high speed modem 8 for demodulation, and the recording section 11 is based on the demodulated signal. Record on a specified sheet.

When the callee operator confirms that the incoming call lamp 15 is lit in such a situation and the print switch 16 is operated, the number information stored in the memory circuit 17 is recorded in the recording unit 11.
And the number information is recorded on the paper. Also,
The number information is also displayed on the display 18 provided in the facsimile machine so that the telephone number of the other party can be easily confirmed.

In the present embodiment, the called side operator confirms that the incoming call lamp 15 is lit and operates the print switch 16, and then prints out on the recording unit 11 or displays on the display unit 18, and then first displays the other party's telephone number. You can check it. In this way, since the other party's telephone number can be confirmed only by a specific person, the telephone number is not known to an unspecified number of people without mischief, which is useful for confidentiality protection. However, the operation may be simplified by operating the recording unit 18 to record the telephone number when the telephone number information is received in response to the voice message. In this case, the incoming call lamp 15 and the indicator 18 do not have to operate.

Further, when the calling telephone sends a DP signal instead of the MF signal, the loop detection circuit 2 and the control unit 13 can detect the number information.

Although not described in this embodiment, it may be implemented as follows.

Although the incoming call lamp is used as the notification means, a buzzer may be used in place of the incoming call lamp, or a mechanism that displaces in response to an input signal and switches the display content may be used.

The telephone number information sent by the calling side need not be the calling party's own number.

, The phone number information is in a preset format for the year,
The month, day, time, etc. may be included.

As described above, in order to confirm whether the stored telephone number information is appropriate for the calling side, accurate telephone number information can be stored, and an incorrect telephone number can be stored. It is possible to provide a facsimile device that is extremely easy to use without
