Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine, and particularly to a facsimile machine that shares two lines with a telephone set.

(Prior Art) In a facsimile machine, after receiving a message, if there is a conversation request from the other party, or if the other party is using a telephone even though automatic reception is received, it is necessary to call the operator of the receiving facsimile machine. be.

However, since the call has been set after going off-hook, no ringing signal is input from line 1 (exchange), and the telephone bell cannot ring.

Therefore, as shown in FIG. 4, the conventional facsimile machine is equipped with a ringing element and causes the ringing element to ring. That is, the conventional facsimile machine 1 has a switching device 2, a ringing signal detector 3, a rectifying circuit 4, a ringing switching section 5, and a ringer I.

2. It is equipped with a control section 13, a unit section 14, etc.
The rectifying circuit 4, the ringing switching unit 5, the ringer IC 6, the ringing element 7, the dialer circuit 9, and the telephone call circuit 10 are the telephone circuit 15.
It consists of

Lines Lt and Lx are connected to the switch 2, and the switch 2 selectively switches and connects the lines L+ and Lz to the telephone circuit 15 side and the line protection circuit and modem 12 side. Switcher 2
is usually the line Ll, L! is connected to the telephone circuit 15, and when a calling signal is input from the lines LI and Lx, the calling signal detector 3 detects it and outputs the detection result to the control section 13. The control unit 13 connects the ringing switching unit 5 to the rectifier circuit 4, drives the ringing element 7 with the ringer IC 6, and causes the ringing element 7 to ring a predetermined number of times. handset 11 for a predetermined number of times.
If the line L1 . L! switch to the line protection circuit and modem 12 side. At this time, if the other party is a facsimile machine, control signals are exchanged and normal facsimile communication is performed. However, even if the switch 2 switches the lines L+ and Lz to the line protection circuit and modem 12 and closes the call, the C
If no NG signal (calling tone) is input, the other party is a telephone and it is necessary to call an operator. However, because a -1 call is set, the line is disconnected.
No calling signal is input from L. Therefore, the control section 1
3 switches the ringing switching unit 5 to the DC power supply 8;
A ringing power source is supplied to the ringer IC 6 to cause the ringing element 7 to ring. When the operator goes off-hook due to the ringing of the ringing element 7, the switching device 2 switches IL+ and Lz to the telephone circuit 15 side to enable a call.

(Problem to be Solved by the Invention) However, in such conventional facsimile machines, when a calling signal is received from lines L+ and Lz,
Afterwards, since the same ringing element 7 rings with the same sound quality as when it was determined that the other party was a telephone, the operator could not determine whether it was a facsimile communication or a telephone call, and took appropriate measures immediately. I can't take it. As a result, there has been a problem that the usability and convenience of facsimile machines are poor.

(Purpose of the Invention) Therefore, the present invention has the objective of changing the sound quality between the ringing sound caused by the ringing signal from the line and the ringing sound that is emitted when it is determined that it is a telephone call, thereby making it possible to tell that the ringing sound is a telephone call. The purpose of this system is to make it clear to the operator that they can quickly take appropriate responses to ringing sounds, thereby further improving the usability and convenience of facsimile machines.

9Φ switching is performed to execute the ringing process of the present invention. The unit section 36 is a general term for all other units normally included in the facsimile machine 21, such as a scanner, a plotter, and an encoding/decoding unit.

Next, the effect will be explained.

The present invention is characterized by the ringing process of the ringing element when calling an operator when the receiver is a telephone or when a conversation request is received during reception.

This ringing process will be explained below based on the flowchart shown in FIG.

In the initial state, the switching device 22 connects the lines L+ and Lx to the telephone circuit 37, and when a calling signal is input from the lines L+ and Lx, the calling signal detector 23 detects it and notifies the control unit 35. The control unit 35 is a call signal detector 23.
When the receiver receives a signal indicating that a calling signal has been detected, the ringer IC 26 connects the ringer switching section 25 to the rectifier circuit 24 and causes the ringer IC 26 to ring the ringer element 27. At this time, the control section 35
The analog switch SW of the sound quality changer 29 is connected to the resistor R1 side, and the ringing element 27 rings at a predetermined frequency. If the controller 35 rings a predetermined number of times and is not off-hook, it sends a switching signal to the switch 22 to switch the lines L+ and Lx.
is connected to the line protection circuit and modem 34 side to close the call.

After closing the call, the control unit 35 outputs a CNG signal (
It is determined whether the other party is a facsimile machine or not based on whether a calling tone (calling tone) is detected (step P1). If the other party is a facsimile machine, normal facsimile procedures are executed (step P2).

When the other party is a telephone, the control unit 35 switches the sound quality switch 2
9 outputs a sound quality switching signal to switch the analog switch SW to disconnect the resistor R1 (step P3), and outputs a ringing switching signal to the ringing switching section 25 to connect the ringer IC 26 to the DC power supply 28 (step P4). . therefore,
The ringer IC 26 causes the ringing element 27 to ring using power from the DC power supply 28, but at this time, since the resistor R of the tone quality switch 29 is disconnected, the ringing element 27 is ringed by the ringing signal from the lines Lr and Lx. The frequency is different from when it rings, and the sound quality of the ringing changes. the result,
The operator can quickly learn that the other party is using a telephone and that the telephone is ringing for a call. Therefore, it is possible to respond promptly and appropriately to the ringing sound, and the usability of the facsimile device 21 is improved.
Convenience can be further improved.

When the operator goes off-hook due to this ringing sound (step P), the off-hook detector 32 detects this off-hook. The detection result of the off-footer detector 32 is transmitted to the control unit 3.
5, the control unit 35 turns off the ringing switching signal from the ringing switching unit 25 to stop the ringing element 27 (step Ph), outputs a switching signal to the switching device 22, and switches the line. Switch L+, r, and z to the telephone circuit 37 side (step P?). This allows the operator to talk to the other party.

In the above explanation, we have explained the ringing process when calling an operator when the other party is using a telephone during reception, but this is not limited to this. It can be similarly applied to etc.

(Effects) According to the present invention, the sound quality of the ringing sound can be changed depending on whether the ringing signal is a call signal from the line or the case where the ringing sound is a telephone call, thereby informing the operator that the ringing sound is a telephone call. Can communicate clearly. As a result, it is possible to quickly and accurately respond to the ringing sound, and the usability and convenience of the facsimile apparatus can be further improved.
