Problems to be Solved by the Invention 2 In telephones, the caller and the called party only communicate with each other in words, and it relies on the image of the receiver, so it is difficult to do things like match numbers, etc. There is a drawback that omitted content may be misunderstood.

Recently, facsimile machines are used to transmit documents, but there is a drawback that if a facsimile machine is not nearby, for example, when you are out and you do not have a facsimile machine, you cannot transmit documents.

In order to eliminate such drawbacks, the present invention has developed a system that allows telephones and facsimile machines to be used on the same line by inserting a charge such as a so-called telephone card or coins currently used in public telephones, or banknotes in the future. It is to make it.

Means for Solving the Problems The present invention combines a public telephone system and a facsimile system and provides a switch or switching element that can send out a signal for transmission when a fee can be collected, in a pay telephone/facsimile system that can be switched manually or automatically. and a usage unit counting circuit that sends out a charging signal when the usage unit corresponding to the usage fee has elapsed, and the switch is closed when the usage fee can be collected, and when the usage fee is insufficient, the usage unit counting circuit transmits the charging signal. The goal is to stop traffic signals.

Function: In the present invention, either the currency mechanism or the card mechanism receives telephone or facsimile usage fees using coins or fee substitute cards such as telephone cards and credit cards to the central office via the currency control section or the card control section. ``to enable the use of the public telephone control device of the public telephone basic system or the closing of a facsimile control device and a switch which causes this facsimile control device to emit a signal for transmission'' (into a transmission circuit or transmission The information is transmitted from the circuit to the office side via the interface.The handset can also be used for both telephone and facsimile since it can be automatically switched from telephone to facsimile.

Furthermore, the facsimile transmission signal is automatically stopped by a usage unit counting circuit when the usage fee is insufficient.

EXAMPLES Hereinafter, one embodiment of the present invention and other embodiments will be explained with reference to the drawings.

In the figure, FIG. 1 is a perspective view of the pay telephone/facsimile machine A, FIGS. 2 and 3 are block diagrams of the main parts, FIG. 4 is a partial electrical circuit diagram, and FIG. FIG. 6 is a perspective view of the telephone basic mechanism, interface, and facsimile body mechanism, and FIG. 6 is a block diagram of the main parts.

When coins, telephone cards, or banknotes (not shown) are inserted into either the coin slot L, telephone card slot 2, or bill slot 3 provided on the front of the paid telephone/facsimile machine A, the usage fee can be used. A currency mechanism 16 having a fee detection device 4 or a card mechanism 17 having a card reader generates an output to a currency control section 18 or a card control section 19, and the telephone is installed in a well-known public telephone basic mechanism 20 or a well-known facsimile basic mechanism 22.

used to manipulate numbers.

In the figure, 14 is a coin return slot, and 15 is a card return slot.

Figure 4 shows a specific example of an interface circuit.
27 is a card control section, and 27 is a public telephone control section 21. 28 and 29 are processors, data lines BDO for sending code signals perform bidirectional transmission, and BG lines determine input-output relationships. By employing the interface 25, it is easy to connect the telephone basic mechanism 20 and the facsimile basic mechanism 22, and the processor, its peripheral circuits, and usage fee collection function can be integrated.

FIG. 5 shows that a facsimile basic mechanism 22 is connected to a paid telephone basic mechanism 20 through an interface 30 such as a connector or a terminal (not shown), and an automatic switching function 28 that serves both a telephone and a facsimile is connected to the interface 3.
0, or provided in either the basic telephone mechanism 20 or the basic facsimile mechanism 22. By connecting the paid telephone basic mechanism 20 and the facsimile basic mechanism 22 separately in this way, the substitute's basic mechanism can be separated and combined as appropriate. Furthermore, even if the telephone line of the telephone basic mechanism 22 is directly connected to the terminal part (not shown) of the facsimile basic mechanism 22, the fee for using the facsimile can be collected by a billing signal such as a polarity change pulse in the telephone basic mechanism 20. . Reference numeral 31 in the figure represents an electric wire, and reference numeral 32 represents an operation button switch of the facsimile basic mechanism 22.

In addition, in Figure 1g6, a hook switch H3 is inserted between the line terminal connected to the telephone line from the telephone office side and the telephone circuit T, and the usage fee is charged in parallel with the telephone circuit T. A signal detection section KD is provided. Thereby, charging signals such as polarity inversion pulses sent from the telephone office at the start of a call and every time a predetermined unit call time elapses are detected, and the output of this detection is applied to the control unit CT.

When the card is used, the number of calls recorded on the card is read, and the remaining number of calls is written at the end of the call, and the card is ejected from the card unit CU.

The control unit CT outputs the detection output and reading result of this card.
At the same time, the card is taken in and ejected according to control from the control unit CT. Note that the 111!1 section CT is given a signal from the hook switch H32, and based on this signal, the control section CT determines on-hook and off-hook.

When detecting money inserted from the money unit MC or if the card inserted from the card unit CU has a record of the number of calls, the control unit CT switches the hook switches H3, H32.
When the caller goes off-hook, the call circuit T or the facsimile circuit FAX is controlled, allowing the caller to make a dial call.

This dialing is switched automatically or manually by either the telephone or the facsimile using a changeover switch C5 such as a relay or push button switch, so the converter (not shown) responds to this dialing and the conversion connection is established. In response to polarity reversal of the voltage applied to the called party's telephone line, facsimile line, or both lines, the charge signal detection unit KD generates a detection output signal.
The processor CPU of T subtracts the number of calls or facsimile transmissions from the call number of the card or usage fee such as coins to a variable memory RAM (random access memory) to enable the call or transmission.

Furthermore, if the continuation usage fee is additionally collected, a billing signal is sent along with the maintenance, so a detection output is generated from the billing signal detection unit KD each time, and the remaining points are subtracted in the same way as above. .

Upon termination of the telephone or facsimile call, the processor CPU reads the remaining card count from the variable memory RAM, sends it to the card unit CU, and sends a signal to the card unit CU to return the card, and the card is returned to the card return slot 15. Ru.

Effects of the Invention The present invention provides a basic telephone mechanism, a basic facsimile mechanism, a fee collection means that can automatically collect usage fees for the basic telephone mechanism and the basic facsimile mechanism, and a usage unit for sending and transmitting telephones and facsimiles. By providing a usage unit counting circuit means for counting and a transmission switch that is closed when a facsimile is transmitted, facsimile usage charges can be automatically collected and the facsimile can be used for both telephone and telephone functions. It is sufficiently deep.
