Abstract

PURPOSE:To switch a telephone from facsimile equipment performing an automatic receiving operation to a subordinate telephone set based on a tone signal from a telephone set at a caller side. CONSTITUTION:In the facsimile equipment automatically performing a receiving operation replying to a call from an external telephone set, the tone signal sent out from the telephone set is detected by a tone detecting part 7, and a facsimile receiving operation is stopped, and also, a ringer tone is inputted to the telephone set 4 by activating a ringer generating part 8, and off-hook is confirmed, then, the telephone circuit 1 is switched from a FAX main body 3 to a telephone set 4 side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to switching and controlling a telephone line.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing an example of a conventional facsimile apparatus. In the figure, 1 is a telephone line,
It is switched and connected to the FAX main body 3 or the telephone 4 via the network control circuit 2 (the telephone 4 is connected during standby). When the FAX main body 3 is set to the automatic reception mode, the call detection unit 5 starts detecting a call signal from the exchange and outputs it to the control unit 6 in response to a call from an external terminal. Even when the calling terminal is a telephone, the control unit 6 instructs the network control circuit 2 to connect the line to the FAX main unit 3 when the calling signal reaches a preset number of times, and automatically sends a facsimile. Enter the receiving operation. Then, first, the response signal (CED signal of 2100 Hz) indicating the terminal connection is returned to the partner device, and then the next procedure signal is transmitted. After the DIS signal for displaying the receiving function and the like is repeatedly transmitted a predetermined number of times, for example, 35 seconds to monitor the response of the partner device, it is determined that the calling terminal is not responding, and the communication is terminated. Therefore, in the case where the facsimile machine is still set to the automatic reception setting, the calling side only hears the signal sound from the facsimile machine, and eventually the line is opened and the intended call cannot be performed. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and in the case of automatically entering the facsimile receiving operation in response to the calling of the calling terminal in the state of the automatic reception setting, (EN) A facsimile device in which a predetermined signal sent from a calling side telephone is received to stop a facsimile reception operation, and a switch of a network control circuit is switched from a facsimile main body to an attached telephone side.

[0004]

SUMMARY OF THE INVENTION To solve the above problems, the present invention provides a facsimile apparatus having an automatic reception function, a tone detecting section for detecting a predetermined tone signal from a telephone set on the calling side, and a tone detecting section. A ringer generation unit that outputs a ringer signal to the attached telephone based on the detection result of the unit,
An off-hook detecting unit for detecting off-hook of the attached telephone is provided, and the facsimile machine which automatically starts the receiving operation in response to the call from the calling side telephone, receives the tone signal from the telephone and facsimiles it. (EN) Provided is a facsimile device configured to stop a reception operation and switch a telephone line from a facsimile main body to an attached telephone side.

[0005]

With the above-described structure, in the facsimile apparatus according to the present invention, when the facsimile receiving operation is automatically started in response to the calling of the calling terminal in the automatic reception setting state, the calling side telephone is set. Detects a predetermined tone signal sent from the machine, stops the facsimile reception operation, activates the ringer generator, inputs the ringer signal to the attached telephone, confirms off-hook, and then attaches the telephone line from the facsimile body. Switch to the telephone side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a facsimile apparatus according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of essential parts of an embodiment of a facsimile apparatus according to the present invention. In the figure, the same parts as those in FIG. In the figure, 7 is a tone detector.
Detects the tone signal sent from the calling telephone.
A ringer generator 8 outputs a ringer signal to the telephone 4 based on the detection result of the tone detector 7. An off-hook detector 9 detects the off-hook of the telephone 4 and informs the controller 6 and the ringer generator 8 of it.

Next, the operation of the facsimile apparatus according to the present invention will be described. The line changeover switch of the network control circuit 2 is normally connected (on standby) to the telephone 4 side. When there is a call from an external device with the automatic facsimile reception setting, as described above, the call detection unit 5 detects the call signal a predetermined number of times and switches the line changeover switch of the network control circuit 2 to the FAX main body 3 side. The machine automatically enters the facsimile reception operation. Then, the transmission of a predetermined procedure signal is started. The same applies when the calling side makes a call from the telephone, and a signal tone peculiar to the facsimile is heard from the handset. Here, when a preset DTMF tone signal, for example, a signal of "#" is transmitted from the telephone, it is input to the tone detection unit 7 via the network control circuit 2. When the signal detected by the tone detection unit 7 matches the set signal, the control unit 6 stops the receiving operation of the FAX main body 3 based on the detection result, and the ringer generation unit 8 causes the telephone via the network control circuit 2. 4 outputs a ringer signal. The off-hook detector 9 monitors the handset of the telephone 4 responding to the ringer signal, detects the off-hook, outputs a signal to the controller 6, and stops the operation of the ringer generator 8. The control unit 6 can instruct the network control circuit 2 to switch the telephone line 1 from the FAX main body 3 to the telephone 4 side and talk with the telephone of the calling side.

[0008]

As described above, according to the facsimile apparatus of the present invention, when the facsimile receiving operation is automatically started in response to the calling of the calling terminal in the automatic reception setting state, the calling side When the predetermined tone signal sent from the telephone is stopped and the facsimile reception operation is stopped, the ringer generator is activated and the ringer signal is input to the attached telephone, and the telephone line is checked after checking the off-hook. Can be switched to the attached telephone side. Therefore, even if the user forgets to cancel the automatic reception setting of the facsimile machine, a call can be made with the calling telephone.
