Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coin-inserted facsimile system that uses a public telephone line or the like and makes it possible to transmit a document by inserting a coin.

In recent years, facsimiles, which transmit manuscripts such as books and forms over telephone lines, have become popular.
Both use general subscriber telephone lines or dedicated telephone lines and cannot be used by anyone other than the subscriber who installed the facsimile, and it is impossible for other third parties to freely use the facsimile. Ta.

Therefore, for example, when a salesperson reports to the company from outside the company the name, code number, unit price, sales volume, etc. of a product they have just received, they can either contact them orally over a public phone or prepare a slip after returning to the company. The only option is to submit the information, and the former is prone to errors in reading, listening, dictating, etc., while the latter has disadvantages such as delays in making internal arrangements, especially for sales staff who have traveled to remote locations. As a result, it has become necessary to be able to immediately transmit documents such as slips within a company from any location.

In order to satisfy such demands, the present applicant has already proposed a charge-type public facsimile machine that the public can use freely by inserting coins, but in this case, of course, the use of public telephone lines, etc. It is necessary to collect a small amount of call charges and facsimile charges associated with the use of a facsimile transmitter, and in order to collect these charges, a special charge signal sending function must be added to the exchange. It disappears.

In other words, on public telephone lines that allow long-distance calls, this is called the distance-based time difference method, in which the exchange sends a charge signal to the public telephone every time a unit call time elapses depending on the distance of the call, and the telephone is turned on and on standby. coins, and in order to collect a small amount of facsimile usage fees, which are relatively expensive compared to call charges, it becomes necessary to add a separate billing signal sending function to the exchange.

However, it is not easy to add such a special billing signal sending function to a conventional exchange, and it also requires a large amount of expense, so the coin-loading facsimile system does not require any changes to the exchange. was desired.

The present invention aims to solve these problems all at once, and stores coins that have been inserted and are waiting in line with the elapse of a unit call time in accordance with a call charge signal from an exchange, and also stores coins that are waiting for a facsimile machine. During facsimile transmission by the transmitter, the waiting coins are stored according to the facsimile communication time using the facsimile billing signal generated at regular intervals, making it possible to use conventional exchange equipment as is, which is extremely convenient. It provides a coin-input facsimile system.

In addition, when there is no hard credit that has been inserted and is on standby corresponding to the amount to be collected in response to the fax billing signal, the switching circuit is restored to the calling circuit, and the amount corresponding to the amount to be collected in response to the call billing signal is restored. When there are no hard loans on standby, the loop circuit for the exchange is forcibly opened.

Further, when a fax billing signal is generated at the same time as a call billing signal arrives, only the hard loan is collected based on the call billing signal, and after a predetermined period of time has elapsed since the collection, the hard loan is collected using the fax billing signal. This is what I did.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the invention will be described below with reference to figures showing embodiments, but first, a system configuration to which the invention is applied will be described.

Figure 1 is a block diagram of the system configuration.
The PEE is connected to the exchange EX via a telephone line L such as a public telephone line, and the FAX device PEE includes a telephone TEL as a communication circuit, a facsimile transmitting unit (hereinafter referred to as FAX transmitting unit) FT, and a coin storage signal sending unit. On the other hand, the exchange EX has a repeater K-REP that generates a call charge signal according to the passage of a unit call time, and a repeater K-REP that generates a call charge signal according to the passage of a unit call time, and a repeater K-REP that detects the coin storage signal from the signal generator SG and It is equipped with a signal receiver PSLE that registers the total MET.

Figure 2 is a flowchart showing the operational status of the system shown in Figure 1.
When you turn off the telephone number at
Preliminary operation is started in the PFE of the equipment, and then a loop circuit to the exchange EX is configured by inserting a coin as a charge, and a dial call can be made.When a dial call is made, the exchange EX responds and an exchange connection is established with the called party. will be done.

When the called party answers, the call status is established and the telephone
After notifying the called party of the facsimile communication via TEL, confirming that the called party's facsimile receiver is ready, and turning on the communication button, the switching circuit SW shown in Figure 1 will switch to the telephone TEL communication circuit. from
Switching to the FAX transmitter FT, the FAX transmitter enters the transmitting state by inserting a document into the FAX transmitter FT, and begins transmitting an image signal when the first coin is received as a facsimile fee. Note that if the called party's facsimile receiver is equipped with an automatic reception function, it is of course only necessary to operate the communication button immediately after confirming automatic reception.

This state will continue as long as there is a document, and when the document is finished, the switching circuit SW will automatically recover and the telephone TEL will be connected to the telephone line L again, thereby returning to the talking state and receiving the facsimile on the called party's side. After confirming the reception status and performing a check-on, the series of operations is completed and all circuits are restored to their initial state.

During this time, the call charge signal is sent from the repeater K-REP to the fax machine at the same time as the called party responds.
Since the call charge signal is sent to the PFE and thereafter every unit call time elapses, as shown in the time chart in Figure 3 that shows the fee collection status,
Between TEL call-off and call-on,
The first and subsequent call charges are performed sequentially.

Also, at the same time as the FAX transmitter FT starts transmitting,
A fax billing signal is generated at a fixed period in the fax machine PFE, and based on this signal, as shown in Figure 3, from the start to the end of the fax communication, the first billing and subsequent charges of the fax bill according to the fax communication time are charged. It is done sequentially.

When the predetermined coins are stored by each of the above charges, the signal generator SG generates a coin storage signal according to the coin type, such as 10 yen or 100 yen, for example, at a frequency of 10 yen coins. 16KHz, continuous time
When it is a 100 yen coin, it is generated at a frequency of 16 KHz and a continuous time of 750 msec, and is sent to the exchange EX.

This coin storage signal is detected by the signal receiver PSLE, and when the signal corresponds to a 10 yen coin, 1
times, and 10 times when corresponding to a 100 yen coin.
Drives the MET and causes the frequency meter MET to register. Therefore, the frequency meter MET displays a value corresponding to the amount of money stored.

The system is operated as described above, and it is sufficient for the exchange EX to be equipped with a conventional repeater K-REP. Also, the signal receiver PSLE is
The consigned public telephone line for 100 yen coins will definitely be installed in the future, and it is sufficient to use it in a constant standby state.

FIG. 4 is a block diagram showing an embodiment of the present invention, which corresponds to the FAX machine PFE shown in FIG. DP, etc. are shown, and each part is operated under the control of a control unit CT mainly composed of a microprocessor or the like.

The billing signal receiving circuit PR detects the call billing signal from the exchange EX and provides the information to the control unit CT, which causes the control unit CT to control the coin storage unit CR and collect the specified coins. Along with storing it,
Based on the output of the coin detector provided in the coin storage section CR and the coin discriminator that determines the type and authenticity of coins, the total amount of coins inserted and waiting is displayed on the display section DP using a numerical display such as a light emitting diode. and the number of 100 yen coins as high-value coins.

In other words, in this case, coins are inserted into separate slots provided for different types of coins, such as low denomination coins and high denomination coins, i.e. 10 yen, 100 yen, etc., and a coin detector and a coin detector are installed for each coin path. A storage lever is installed, and a coin detector is installed especially in the 100 yen coin path to check the 100 yen coins.
The total amount of waiting coins and the number of 100 yen coins are displayed by counting each detection force of the coin detector installed immediately after the 100 yen coin slot.

In addition, as will be described later, when there are no coins waiting after coin storage, based on the detection power of the coin detector, the switch circuit SW is forced to return or the loop circuit is It is supposed to be a forced release.

FIG. 5 is a block diagram of an embodiment showing the configuration of the control unit CT, which mainly includes a processor CPU such as a microprocessor, an instruction memory ROM, and a data memory.
RAM, timer TM, interface I/O
etc. are arranged, and the information given through the input circuit IPT and interface I/O is processed by the processor.
The CPU receives the information and reads the instructions from the instruction memory ROM.Based on this, the processor CPU generates an output corresponding to the given information, and outputs the necessary information via the interface I/O and output circuit OPT. The control output is sent out as follows.

In addition, there is a coin detector installed immediately after the coin slot.
The input coin detection power of CDT ₁ and CDT ₂ is given directly to the processor CPU via the interrupt circuit ITC because it is necessary to perform immediate processing. In addition, a timer TM is provided to regulate the above-mentioned coin storage signal sending period and each timing operation described later, and a data memory RAM is provided for temporarily storing various data required for the operation of the processor CPU. .

FIG. 6 is a circuit diagram of an embodiment showing the main parts of the FAX machine PFE, which operates in cooperation with the control unit CT as shown in the flowchart of FIG. 7 showing the operating status.

In Fig. 6, line terminals L ₁ and L ₂ are connected to the exchange EX via telephone line L, and power from the exchange EX is normally applied with line terminal L ₁ as (+), but the When the caller responds and when the repeater K-REP in Figure 1 generates a call charge signal,
The line terminal _L2 side becomes (+) for a certain period of time, and upon detecting this, an operation is performed to store coins that have been inserted and are waiting.

In addition, since the FAX transmitter FT requires a motor drive power source, document illumination power source, etc., this device uses a commercial power source, and each part that requires a DC power source is equipped with a rectifier circuit (not shown in the diagram). After obtaining the DC power supply V, the transistor of the power supply circuit PS ₁
It is supplied to each part via a switching circuit consisting of Tr ₁₀ and resistors R ₄ and R ₅ .

In addition, the coin detector CDT ₁ in the coin storage section CR
CDT ₅ connects light-emitting diodes LD ₁ to LD 5 and photo transistors PT ₁ to _{LD 5} facing each other via a coin path.
PT ₅ is installed, and when there is no coin, the light emitted from the light emitting diode LD ₁ is activated by a phototransistor.
Since the light is incident on PT ₁ to _{PT 5} , the photo transistors PT ₁ to _{PT 5} are turned on, and the input c of the control unit CT
~h is set to a low level (hereinafter referred to as "L"), but since the light emission of the light emitting diodes LD ₁ to _{LD 5} is blocked due to the interposition of the coin, the photo transistors PT ₁ to
PT ₅ is turned off and resistors are connected to these collectors.
The power supply voltage applied via R ₁₇ to R ₂₁ is generated as a high level (hereinafter referred to as "H"), and this is applied to each input c to h.

In addition, the coin discriminator CSL is equipped with a transmitter coil and a receiver coil that are arranged opposite to each other through a coin path, and the transmitter coil is excited by alternating current of a constant frequency and a constant current value, and the magnetic field generated from the transmitter coil is The receiving coil is designed to detect this, and if the amount of electromagnetic coupling between both coils changes due to the absence of a coin or the presence of a coin, the detection voltage from the receiving coil will also change, and this amount of change will determine the material of the coin. Due to this principle, 10 yen coins, 100
It distinguishes yen coins, etc., and determines the authenticity of coins.

In this case, these coin detectors CDT ₁ to CDT ₅ and coin discriminator CSL are placed in the coin paths for 10 yen coins and 100 yen coins, respectively, and the coin detectors are placed immediately after the 10 yen coin input slot. CDT ₁ has a coin detector in the coin waiting position just before the 10 yen coin storage lever.
A coin detector CDT ₃ is installed between the 10 yen coin storage lever and the storage safe, and a coin detector CDT ₂ is installed immediately after the 100 yen coin slot, and a coin detector CDT ₂ is placed in the standby position just before the 100 yen coin storage lever. Discriminator CSL has a coin detector between the 100 yen coin storage lever and the storage safe.
Equipped with CDT ₄ , coin detector immediately after each slot
CDT ₁ and CDT ₂ detect the number of coins inserted as described above, and the coin detector CDT ₅ and coin discriminator CSL immediately before each storage lever detect the presence or absence of the next coin to be stored. When each storage lever operates and stores the waiting coins,
The control unit sets the logical conditions that there are no waiting coins and that coins are detected by the coin detectors CDT ₃ and CDT ₄ between each storage lever and the storage safe.
CT is used to monitor and check that coins are being stored reliably.

In the fax machine PFE having such a configuration, when the hook is first turned off as shown in FIG. 7, the switch HS ³ is turned on and a forward voltage is applied to the transistor Tr ₁₀ of the power supply circuit PS ₁ via the diode D ₉ and the resistor R ₆ . Bias is applied and it turns on, starting to supply power to each part, and the transistor
Tr ₈ is also turned on by being forward biased through diode D ₈ , and each coin detector
Due to the current flowing through the routes of the light emitting diodes LD ₁ to LD ₅ of CDT ₁ to CDT ₅ and the resistors R ₁ and R ₂ , a collector current flows based on the Zener voltage occurring in the Zener diode ZD, and the collector current flows through the resistor R ₃ .
The terminal voltage of is applied to the input c of the control unit CT.

Then, the processor CPU reads an instruction from a predetermined address in the instruction memory ROM based on the information on input c, thereby clearing the data memory RAM and preparing for a new operation.
The output s is generated at a high level (hereinafter referred to as "H"), turns on the transistor Tr ₁ , excites the coin return prevention magnet RM of the coin storage section CR, operates the input coin return prevention lever, and accepts the input coin. state.

Next, when 10 yen and 100 yen coins are inserted,
The coin detectors CDT ₁ and CDT ₂ detect this, and the detection force is set to "H" and input g, h to the control unit CT.
As a result, the output O is generated from the control unit CT as "H", the transistor Tr ₅ is turned on, the relay LP is operated, its contacts lp ¹ to lp ³ are made, and the contact lp ² is turned on. At the same time, the loop circuit is constructed with the hook switch HS ¹ , which is connected to the switch HS1, and at the same time, the contact LP ³ supplies power to the signal generator SG and the tone generator TG that generates the coin insertion reminder sound, and prepares the transmission conditions. Let's do it.

On the other hand, the control unit CT receives the detection forces of the coin detector CDT ₅ and the coin discriminator CSL to inputs d and k, and after confirming that preparations for transmission have been made, sets the output p to “H” and turns on the transistor Tr ₄ Turn on, operate relay RL, and make its contact RL.

Then, the positive direction loop circuit is created by contact lp ² .
Line terminal L ₁ - Hook switch HS ¹ - Contact ans - Diode D ¹ - Contact lp ² - Dial impulse contact Di - Blocking wire CH ₁ - Diode D ₃ - Blocking wire
CH ₂ - Transmitter T - Diode D ₆ - Relay OL - Line terminal L ₂ In addition, the negative direction loop circuit is also configured as Line terminal L ₂ - Diode D ₅ - Contact
Rrl - Relay kp - Blocking wire CH ₂ - Transmitter T - Diode D ₄ - Blocking wire CH ₁ - Impulse contact Di -
Contact Lp ² - diode D ₂ - switched on switch HS ² - relay ANS - provided as line terminal L ₁ .

However, since the line voltage from the power supply from the exchange EX is still (+) on the line terminal _L1 side, a loop current flows to the forward loop circuit, which operates the relay OL, and the contact OL Ground the input b of the control unit CT and set it to “L” by making.
Gives information on completion of sending preparations.

Next, when you make a dial call, the impulse contact Di turns on and off, and the exchange
EX operates to establish an exchange contact with the called party, and when the called party responds, the call state is established. ₂ and _C3 , the communication voice is transmitted and received. At this time, a speech current is supplied to the transmitter T by the forward loop circuit, but since the voice component is blocked by the blocking wires CH ₁ and CH ₂ , it flows only to the guide wire IND.

In addition, the polarity of the line voltage is reversed at the same time as the called party responds, and the line terminal _L2 side becomes (+) for a certain period of time. As relay KP works.

Then, by making the contact kp, the input a of the control unit CT is grounded and becomes “L”, so this is connected to the control unit.
The CT receives the call charge signal as the arrival of the call charge signal, compares the information from the coin detectors CDT ₁ , CDT ₂ , CDT ₅ and the coin discriminator CSL with the contents of the data memory RAM, and determines whether both 10 yen and 100 yen coins are present. When waiting,
Transistor Tr ₂ preferentially sets output r to “H”
is turned on, the 10 yen coin storage magnet CM10 of the coin storage section CR is energized, the 10 yen coin storage lever is driven, and only one 10 yen coin is stored.

When only the 100 yen coin is on standby, the output q is set to "H", transistor Tr ₃ is turned on, and the 100 yen coin storage magnet in the coin storage section CR is turned on.
The CM100 is excited to drive the 100 yen coin storage lever to store only one 100 yen coin, store this information in the data memory RAM, and output q until the 10th charge based on the subsequent call charge signal. , r
This prevents both of them from switching to "H". Yes,
Regardless of this condition, the output q is set to "H" in response to a fax billing signal, which will be described later, and a 100 yen coin is stored based on the fax billing signal.

Coin detector CDT ₃ ~ as described above for storing coins
CDT ₅ , control unit CT by the output of coin discriminator CSL
is confirmed, the output n is set to “H” and the transistor Tr ₆ is turned on, thereby turning on the signal generator SG.
is operated for a period of time according to the type of stored coins regulated by the timer TM, and a coin storage signal is generated. This coin storage signal is applied to the varistor VR via the transformer _T1 , becomes a substantially constant level, and is sent to the exchanger EX via the capacitor _C1 and the line terminals _L1 and _L2 , where the frequency is increased as described above. total
Register MET.

Note that when the next coin to be stored does not arrive at the standby position after storing the coin, the coin detector _CDT5 ,
Based on the output of the coin discriminator CSL, the control unit CT sets the output m to "H", turns on the transistor Tr ₇ , operates the tone generator TG, generates a reminder tone of, for example, 400 Hz, and then connects the transformer T ₂ and the capacitor C. ₄ to the receiver R to prompt the user to insert a coin.
However, this output m is approximately 500 m due to the timer TM.
It is regulated to occur only during a period of msec.

In the above call state, after confirming that the called party's facsimile receiver is ready, turn on the communication button (not shown in the diagram), and this will activate the switching circuit.
SW switches, FAX transmitter FT connects capacitor C ₂ ,
It is connected to the line terminals L ₁ and L ₂ via C ₃ , and at the same time as the hook is turned off, the FAX transmitting unit power supply circuit PS ₂ is turned on by the output u of the control unit CT, so it becomes operational immediately when the original is inserted. When a synchronization signal is transmitted to the called party and a phase matching completion signal is received from the called party, the synchronization completion signal is applied to the input j of the control unit CT, and at the same time, facsimile transmission is started.

The control unit CT starts the timer based on the information of input j.
The generation of a constant periodic fax billing signal using TM is started, for example, at a period of 100 seconds, and each time the signal is generated, the output q is set to "H", and 100 yen coins are sequentially stored. During this time, if there is a polarity reversal of the line voltage by the exchange EX, the above call charge will be applied.
10 yen coins will be collected one after another.

However, when the fax billing signal and the call billing signal due to the inversion of the line voltage occur simultaneously, the control unit CT determines this and temporarily stores the generation information of the fax billing signal in the data memory RAM.
After coin storage is performed preferentially based on the call charge signal, coin storage is performed based on the fax charge signal after a certain period of time has elapsed due to the operation of the timer TM. This is to make the frequency meter MET register 10 times according to the storage of 100 yen coins on the EX exchange side, and then register according to the call charges. total
The time required for MET to register 10 times, i.e.
Generally, it is determined based on approximately 4 seconds.

Also, at the same time when input j is given, control unit CT
sets the output t to "H", and operates the relay F, which short-circuits the transmitter T through its contact f and makes it inoperative, thereby preventing noise from being mixed into the facsimile signal from the transmitter T.

The above state continues as long as the document is inserted into the FAX transmitting section FT, and information that does not indicate whether the final document has been transmitted is provided from the FAX transmitting section FT to the input i of the control section CT.

In addition, a relay is used in the switching circuit SW, and it continues to operate according to commands from the control unit CT.
When this command is released, the line terminal _L1 ,
Reconnect L ₂ to the talking circuit.

When the information associated with the completion of transmission of the final manuscript is given to the input i, the control unit CT sets a certain hold time by the timer TM, and after 7 to 8 seconds, for example, the switching circuit
The SW is automatically restored, the output t is changed to "L", the relay F is also restored, the transmitter T is put into operation again, and a call can be made using the communication circuit.

After confirming the facsimile reception status of the called party through a telephone call, when the facsimile reception status is checked and the facsimile reception status is turned on, the loop circuit is opened by turning off the facsimile switches HS ¹ and HS ² , the exchange EX is restored, and the transistor Tr is turned off by turning off the facsimile switch HS ³ . ₈ is turned off, and the input c of the control unit CT becomes "L".

Then, the control unit CT returns each output to "L", restores the relays RL and LP, and at the same time releases the power-on state of the FAX transmitter power supply circuit Ps ₂ to return to the initial state.

However, the transistor Tr ₁₀ of the power supply circuit PS ₁ is
Control unit CT through resistor R ₈ to transistor Tr ₉
The output l of the transistor is given as “H”, and the transistor
Since Tr ₉ is on, even if the switch HS ³ is turned off, a forward bias is applied through the transistor Tr ₉ and the resistor R ₇ , so the on state is maintained, and the timer TM After a predetermined period of time has elapsed, the output l changes to "L" and then turns off, stopping the power supply to each part. As a result, the output s of the control unit CT also becomes "L", and the coin return prevention magnet RM is excited. will be lifted, and any remaining coins will be returned.

This is considered as a countermeasure for the purpose of reliably storing coins and sending out a coin storing signal when the coin storing operation is started immediately before the hook-off.

In addition, when coins equivalent to the amount to be collected based on the fax billing signal are not collected during facsimile transmission, that is, in this case,
When there are no 100 yen coins, the control unit CT determines this, restores the switching circuit SW, and only allows calls for the remaining coins. In addition, when it is impossible to store coins equivalent to the amount to be stored based on the call charge signal, that is, when there are no 10 yen and 100 yen coins in this case, the control unit CT outputs O and P as “ "L", relays RL and LP are restored, the loop circuit is forcibly opened, the call is blocked, and the exchange EX is restored.

On the other hand _{, the} display unit DP is composed of display devices DPE ₁ to DPE ₄ as shown in the block diagram shown in FIG. However, the display device DPE ₄ is designed to display the number of waiting 100 yen coins as a one-digit number, and as mentioned above, the control unit CT counts the coin detection information and the result is stored in the data memory RAM. Display data Sd and display commands Sc ₁ to _{Sc 4} are given as time-division signals, which are held by drivers DR ₁ to _{DR 4} including latch circuits and decoders, and displayed by display devices DPE ₁ to Sc 4. The DPE ₄ is driven and a predetermined display is performed.

In addition, the decrease in the number of waiting coins due to coin storage and the increase in the number of waiting coins due to new coin insertion are sequentially calculated by the processor CPU of the control unit CT, and at the same time, the contents of the data memory RAM are updated, and at the same time, the display command Sc ₁ ~Sc ₄ occurs, each time driver DR ₁ ~
Since DR ₄ retains new display data Sd,
The current status is always displayed.

Note that after storing coins based on the call charge signal, when there are no more coins to be stored according to the next call charge signal, the control unit CT determines this and sends out a blinking signal Si ₁ to display the indicators DPE ₁ to DPE. ₃ will flash, and after storing the coins based on the fax billing signal,
When there are no more 100 yen coins on standby, a similar flashing signal Si ₂ is sent out and the display on the display device DPE ₄ is flashed to send out the above-mentioned reminder sound and display a request to insert additional coins.

As described above, coin storage in the fax machine PFE is carried out rationally and reliably, but since the fax billing signal is generated within the own machine,
There is no need to add a special billing signal sending function to the exchange EX, and conventional public telephone lines can be used as is. Call charges are billed based on the time difference method based on distance, and billing is based on facsimile communication time. This is done in parallel without any contradiction, and facsimile communication can be continued for the required period by inserting coins.

In addition, since a fax billing signal is generated after the phase matching with the called party's facsimile receiver is completed, if the receiving mode of the called party's receiver is different and facsimile communication is not possible, the facsimile communication There is no risk of being fined for the relatively high fees associated with faxing, and only 100 yen coins are accepted depending on the fax billing signal, so the number of coins for each type should be estimated and prepared in advance. This makes it possible to avoid a situation where a facsimile communication is forcibly disconnected due to a lack of coins.

Note that when it is impossible to store coins based on the fax billing signal, the call circuit is simply switched to, and retransmission, etc., can be performed after discussing post-processing with the called party.

Furthermore, when a call billing signal and a fax billing signal occur at the same time, coins are not stored based on both signals at the same time, so that the register of the frequency meter MET is ensured, and coins are deposited reliably. .

In addition, it is also possible to use coins other than 10 yen and 100 yen as low denomination and high denomination coins, and a dedicated logic circuit may be used in the control unit CT without using a processor CPU. Various modifications are possible.

As is clear from the above explanation, according to the present invention, a fixed charge is collected in accordance with the elapse of a unit call time in accordance with a call charge signal from an exchange, and in parallel with the collection, a facsimile transmission signal is sent at a fixed cycle. By storing hard-line charges according to the fax communication time according to the generated fax billing signal, there is no need to add a special billing signal sending function to the exchange, so conventional public telephone lines can be used as is. As well as being able to
Charging for call charges based on the distance-based time difference system and charging according to the facsimile communication time are performed in parallel without contradiction, and facsimile communication can be continued for the required period by inserting a hard loan.

In addition, when there are no more coins inserted and waiting in line with the amount to be collected in response to the fax billing signal, the switching circuit is restored to the telephone call circuit, and coins are inserted in accordance with the amount to be collected in response to the telephone billing signal. When there are no hard loans on standby, the loop circuit for the exchange is forcibly opened, so that if it is not possible to store hard loans based on the fax billing signal, the circuit is switched to the call circuit. Therefore, it is also possible to perform retransmission, etc. after discussing post-processing with the called party.

Further, when a fax billing signal is generated at the same time as a call billing signal arrives, only the hard loan is collected based on the call billing signal, and after a predetermined period of time has elapsed since the collection, the hard loan is collected using the fax billing signal. As a result, coin-loading facsimile machines are becoming more popular, as the counter on the exchange side is reliably registered and the coin-loan is stored reliably, since the coin-loan is not stored based on both signals at the same time. Great effects can be obtained.
