[0003]

As described above, in the conventional telephone device, it is possible to settle the call charge by calculating the call charge for the outgoing call and displaying the result. On the other hand, in the conventional telephone device, since the call charge cannot be properly settled for the incoming call, the following problems occur. That is, when a user makes a call to a company that sells the product due to a complaint about the product, the call charge should be borne by the sales company, which is originally the receiving side. It is a burden. For this reason, the sales company, which is the receiving side, is studying that the calling fee should be properly settled and paid by the user so that such a calling charge is not burdened by the user.

Therefore, an object of the present invention is to make it possible to accurately calculate and settle the call charge when the callee bears the call charge, such as in the case of the above-mentioned product complaint, collect call, toll-free dialing, etc. .

[0005]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention provides a telephone device which detects an incoming signal from an exchange coming through a telephone line and outputs a ringing tone together with the incoming signal.

Reference numeral 18 is a modem, which has external lines L1 and L
When an incoming call arrives at 2, the caller telephone number, which will be described later, transmitted from the exchange side together with this incoming signal is relayed to the relay RY,
CPU received via capacitor C2 and transformer T
It is transmitted to 1. Reference numeral 20 denotes a charge update timer, which is a timer for updating the unit call charge during a call. In addition, HS1 is a hook switch, PC is 16Hz
The photocoupler for transmitting the incoming signal detected by the detection circuit 19 to the CPU 1 and the SW are switches for controlling the output of the incoming signal detected by the 16 Hz detection circuit 19 to the buzzer BZ.

By the way, when the absence setting key in the function keys 17 is operated, the absence mode is set in this apparatus.
When an incoming call arrives at the accommodated outside lines L1 and L2 during the absence mode, the incoming call signal is transmitted to the CPU 1 via the 16 Hz detection circuit 19 and the photocoupler PC. In this case, the CPU 1 sends the transistor Q via the dial circuit 2.
Turning on transistor 2 turns on transistor Q1,
The DC loop of the outside lines L1 and L2 is closed to respond to the incoming call.

Thereafter, the audio recording / reproducing circuit 7 is driven to perform recording / reproducing I.
The response message recorded in C8 is sent to the outside lines L1 and L2 via the voice recording / reproducing circuit 7, the amplifier 9, the communication circuit 6 and the like. Then, in response to the transmission of the response message to the calling side, the recording / reproducing IC 8 is caused to record the message message from the calling side arriving at the outside lines L1 and L2 via the communication circuit 6, the amplifier 9 and the voice recording / reproducing circuit 7. The calling side message recorded in the recording / reproducing IC 8 in this way is emitted from the speaker SP via the voice recording / reproducing circuit 7 and the amplifier 9 when the reproduction key (not shown) in the function key 17 is operated.

On the other hand, when the absence mode is not set in this device, this device operates as a normal telephone device.
That is, when an incoming call arrives at the accommodated outside lines L1 and L2 due to a call made to this device on the calling side, this incoming signal is 1
It is sent to the buzzer BZ through the 6 Hz detection circuit 19 and the switch SW whose contacts are normally closed, and the buzzer BZ sounds a ringing tone, for example, for one second on and two seconds off. When the user of this apparatus notices this ringing sound and goes off-hook, the contact of the hook switch HS2 is closed and the transistors Q2 and Q1 are turned on, thereby closing the DC loops of the external lines L1 and L2. Then, the loop line connection of the outside lines L1 and L2 makes a response to the incoming call, and an outside line incoming call answering call with the calling side of the user is realized. When the calling side makes a call to the present apparatus through the exchange, the telephone number of the calling side is recognized by the exchange.

Here, if the telephone number of the caller of the other party can be transmitted together with the incoming signal of 16 Hz to the receiving side from the exchange connected to the outside lines L1 and L2 at the time of receiving a call, such a telephone number of the calling party can be obtained. On the device side, as described above, it is possible to receive via the modem 18. When the outside lines L1 and L2 are ISDN lines, the caller telephone number is included in the calling address and is transmitted from the exchange side.
The CPU 1 can execute a predetermined protocol process to receive the caller telephone number.

By the way, in some of such answering machine, it is possible to calculate and display the call charge for a call made from the own device. However, if you make a call to the sales company of the product due to a product complaint, or if the called party bears the call charge, such as collect call and toll-free call charges, the callee must pay the call charge properly. There is a problem that it cannot be calculated. Therefore, in the present apparatus, by using the above-mentioned caller telephone number, it is possible to accurately calculate and settle the call charge borne by the called party.

FIG. 2 is a flow chart showing the operation of the CPU 1 of the answering machine which calculates the call charge using the above-mentioned caller telephone number. The main operation of the present invention will be described in detail according to this flowchart. When the CPU 1 is activated, it executes an initialization process in step S1. Then, after the completion of the initialization process, the CPU 1 executes various processes. In this example, step S2
Then, the external line incoming call detection judgment for detecting the presence or absence of the incoming call to the external lines L1 and L2 through the 16 Hz detection circuit 19 and the photocoupler PC is executed. In addition, the outside lines L1 and L2 are ISD
If it is an N line, the outside line incoming detection detection determination of step S2 is performed in a predetermined incoming call protocol process. When an incoming call to the outside line is detected and the determination in step S2 is "Y", the above-mentioned caller telephone number is received in step S3.

That is, when the external lines L1 and L2 are analog lines, when the incoming call is received, the caller's telephone number is, for example, 2 when the first 16 Hz incoming signal is on and the second 16 Hz incoming signal is on for 1 second. It is assumed that the signal is sent while the incoming signal is off for one second. In this case, the CPU 1 sends the first 16H through the 16Hz detection circuit 19 and the photocoupler PC.
z When the incoming signal is detected and the first incoming signal disappears, the relay RY is driven to close its contact, and the external line L
An AC loop of 1 and L2 is formed. Then, the outside line L1,
The caller telephone number from the exchange side via L2 is relay R
The data is received by the modem 18 via the Y contact, the capacitor C2 and the transformer T, and transmitted to the CPU 1. The CPU 1 inputs this caller telephone number from the modem 18. When the external lines L1 and L2 are ISDN lines, the CPU 1 executes a predetermined incoming call protocol process with the exchange side to receive the caller telephone number transmitted from the exchange side and included in the calling address.

After that, the off-hook detection determination indicating the response operation to the incoming call by the user is executed in step S4. Here, when the user goes off-hook, the contacts of the hook switch HS2 are closed and the transistors Q2 and Q1 are turned on to close the DC loops of the external lines L1 and L2. Then, a response to the incoming call is made by the loop closure of the outside lines L1 and L2, and an outside line incoming call answering call is made with the calling side of the user. In this case, the CPU 1 detects the state of the hook switch HS1 that is interlocked with the hook switch HS2 and determines "off hook" in step S4 to be "Y". In the case of the ISDN line, the incoming call response is detected by executing a predetermined protocol.

When the user of this device responds to the incoming call in this way, the CPU 1 calculates the call charge for this incoming call based on the charge table 13A in the memory 13 which includes each area code and the corresponding call charge information. To do. That is, each area code is provided in the charge table 13A as shown in FIG. Then, the number of call seconds per unit call charge when a call is made from this device to each of these area codes is set according to each time zone of daytime, nighttime, and midnight. The CPU 1 refers to the charge table 13A configured as described above, and in step S5, the clock unit 1
The current time of 5 is read out, the unit call time corresponding to the unit call charge is calculated from the time zone of this call and the area code of the caller's telephone number received at the time of the call. And the calculated unit call time is set in the charge renewal timer 20.
Start 0.

After that, the CPU 1 determines whether the charge renewal timer has timed up in step 6 and detects on-hook by the end of the user's call in step 10. Here, the unit call time elapses during the user's outside line incoming response call, and the charge update timer 20 is timed up, and the step S
When the judgment of 6 is "Y", the charge update timer is restarted in step S7. Subsequently, the CPU 1 executes the "charge update amount display" in which the next unit call charge is added to the previous charge and displayed on the display unit 14 in step S8, and the process returns to step S6 to restart the "charge update timer time". "Up" detection judgment is performed. In this way, during the incoming call, the call charge updated and added one by one is displayed on the display 14 each time the charge update timer expires.

On the other hand, if the charge renewal timer 20 has not timed up, other outside line communication processing is performed in step S9, and then the process proceeds to step S10, in which on-hook detection determination based on the user's end of call is performed. Here, when the CPU 1 detects that the user is on-hook by detecting the state of the hook switch HS1, the CPU 1 stops the fee update timer 20 in step S11, and at this time, for example, a printer or the like is connected to the apparatus. If so, the call charge required for this incoming call and the caller's telephone number corresponding thereto are output and printed on the printer. Further, such an incoming call charge and a caller telephone number can be stored in a separate area of the memory 13 and read out and output to the display 14 or a printer by a predetermined operation. Then, after that, in step S12, an outside line call termination process is performed,
Subsequently, after performing other processing in step S13, the process returns to step S2 to make another external line incoming call detection determination.

If the caller's telephone number is received when an outside line is received and no response operation by the user of the device is detected at this time, the CPU 1 does not perform the call charge calculation and display processing, and other steps are performed in step S14. After processing the incoming call,
The process proceeds to step S13, and other processing is executed. In this way, during the incoming call, the charge table 13A provided in the memory 13 is referred to and the unit call time corresponding to the unit call charge is calculated from the incoming call time zone and the area code of the caller telephone number. Is calculated, the unit call charge is added every time the unit call time elapses, and the charge is updated and displayed on the display unit 14. As a result, for example, when the user makes a call to the sales company of the product due to a product complaint or the like, the call charge can be accurately calculated at the sales company that is the receiving side, and therefore the conventional user side It is possible for the sales company to settle and bear such call charges, which is a burden on the sales company side.

Further, even in the case of a collect call in which the called party bears the call charge or a toll-free access number "0120", the callee can be accurately calculated and settled. Furthermore, for example, when a sales person who travels to a distant place makes a telephone call to the company for a company from a remote location and the call charge is settled on the company side,
Accurate settlement can be performed. In this example,
Although the example of the answering machine has been described, it is obvious that the same can be applied to a single telephone and a key telephone, and the same effect can be obtained in these cases.

[0023]

As described above, according to the present invention, when the caller telephone number sent from the exchange together with the incoming signal is received, the call charge is calculated based on the received caller telephone number, and the calculation is performed. Since the result is displayed, for example, when the user makes a call to the sales company of the product due to a product complaint or the like, the call charge can be calculated at the sales company on the receiving side. It is possible for the sales company to settle and bear such a call charge, which has conventionally been a burden on the user side, on the sales company side. In addition, the call charge is calculated based on the charge table consisting of the area code and call charge information.
Call charges can be calculated accurately on the called side.
