Abstract

PURPOSE:To enable a person not familiar with a facsimile equipment to execute communication by providing a 16Hz ringing signal generating circuit in a facsimile equipment, thereby ringing the bell of a telephone set connected to the equipment. CONSTITUTION:During a FAX transmission of picture signals, the operator on the transmission-side depresses an operator-call SW. When the FAX communication ends and the operator-call arrives, a switch 422 turns to ring-side,and the telephone set immediately made ringing by the 16Hz-ringing signal generating circuit 421. When the called-side operator hooks up the receiver, a hook off detection circuit 423 automatically turns a switch 43 to 'tell' and a switch 422 to a contacting point T1. At this time, a response signal is transmitted to the reception-side and the same action is executed on the reception-side, and hence the bell of the telephone rings. Like on the reception-side, a hook off detection circuit turns all the switches to telephone-side. Consequently, a communication is made possible between the telephones on both sides.

Description

[Detailed Description of the Invention] [Summary] In an automatic facsimile reception system that uses a telephone line and is a telephone calling method, the bell of the telephone of the called party is set to ring by the facsimile machine of the called party. This is what I did.

[Industrial application field]

The present invention relates to a telephone calling system. In an automatic facsimile (FAX) reception system that uses a telephone line, when a 16Hz audio signal for ringing the telephone arrives, the FAX
AX detects this 15Hz signal and the line is transferred from the phone to the FA.
It is designed to switch to the X side.

In such an automatic reception system, the present invention
This invention relates to a telephone calling method for calling a person using a telephone rather than sending and receiving messages.

[Conventional technology]

In the conventional telephone calling system, as shown in Fig. 5, when a caller wants to communicate, he or she first turns the dial from the sending side's telephone 1', and then the receiving side's FAX 4' is called via the sending side's FAX 2' and exchange 3'. It is designed to emit an alarm sound AL.

Next, the called party activates the alarm AL, picks up the handset of the receiving telephone 5', and presses the telephone reservation button to make a telephone call.

[Problem that the invention seeks to solve]

However, in the conventional system shown in FIG. 5, the bell of the telephone 5' itself does not ring directly. The called party must pick up the receiver only after hearing the alarm tone AL from the receiving FAX 4'.

Therefore, only a person who can distinguish the alarm sound for normal telephone communication from among the many types of alarm sounds can pick up the telephone receiver.

That is, in the past, there was a problem in that a person who was not familiar with FAX could not make a telephone call.

[Means for solving problems]

The purpose of the present invention is to solve the above-mentioned problems and to enable even people who are not accustomed to operating FA and X to make telephone calls.

As shown in Figure 1, the means for this purpose is to
A 16 (Hz) ringing signal generation circuit is installed in
z) By operating the ringing signal generation circuit,
This is intended to ring the bell of the telephone 5 on the receiving side.

[For production]

According to the present invention, as described above, it is possible to ring the telephone of the called party using the FAX of the called party.

Therefore, even a person who is not familiar with FAX operation can pick up the receiver and make a call.

〔Example〕

Hereinafter, the present invention will be explained by way of examples with reference to the accompanying drawings.

FIG. 2 is a configuration diagram of an embodiment of the present invention. The overall configuration of the FAX is the same for both the sending and receiving sides, but for convenience, the FAX on the receiving side
This will be explained as 4.

The FAX 4 is composed of a facsimile section 41 and a telephone calling section 42, each of which can be switched by a switch 43.

The facsimile unit 41 is a device that only performs facsimile transmission and reception, and includes a transformer 411, a receiving amplifier 412,
It is composed of a transmission amplifier 413.

The telephone calling unit 42 is a device that calls the telephone 5 and includes a 16Hz ringing signal generation circuit 421, a switch 422, and a hook-off detection circuit 423.

The switch 43 is a switch for switching between FAX and telephone, and the switch 422 is a switch for switching the line to the telephone 5 after calling the telephone 5 using the circuit 421.

Hereinafter, the operation of the apparatus shown in FIG. 2 having the above configuration will be explained based on FIG. 3.

■ First, the bell of the telephone 5 on the receiving side rings due to the 16Hz telephone ringing signal, but the fulcrum rfI of the switch 43
switches to the FAX side contact fax.

■ As a result, the facsimile device 4 communicates with the sending side via the facsimile unit 41, the contact fax, and the fulcrum rj2+.
Performs AX communication. In FIG. 3, signals below CED and up to CFR are signals for normal facsimile communication. While transmitting the FAX image signal, the caller presses the operator call SW on the transmitting side.

■ When the fax communication is completed, the operator call signal/P
- When F, OP (telephone reservation signal) arrives, the switch 42
As shown by the broken line, the fulcrum rβa of No. 2 is switched to the contact ring side, and the 16Hz linking signal generation circuit 42
1 causes the telephone 5 to ring directly. This calls the operator on the called side.

■ When the called operator picks up the receiver, the footer-off detection circuit 423 activates the switch 43 at the fulcrum r1! ,
is automatically switched to the contact te11, and the fulcrum r1a of the switch 422 is automatically switched to the contact T1.

At this time, a response signal PiP or PiN is sent to the transmitting side, and the transmitting side performs the same operation as the receiving side, and the bell of the telephone 1 (FIG. 1) directly rings. Also, the sending side
Similar to the receiving side, the hook-off detection circuit switches all switches on the telephone side.

(2) The above operation enables a telephone conversation between the sending telephone 1 and the receiving telephone 5.

In the above description, the operation on the receiving side was mainly explained, but the time charts for both transmission and reception are as shown in FIG.

〔Effect of the invention〕

As described above, according to the present invention, by providing a 16Hz ringing signal generation circuit in a facsimile machine,
Since it is possible to directly ring the bell of a telephone connected to the facsimile machine, even a person who is not familiar with facsimile machines can make a telephone call.
