7A and function keys such as an answering machine setting key and a reproduction key (not shown).

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. Further, HS1 is a hook switch, PC is a photocoupler for transmitting an incoming signal detected by the 16 Hz detection circuit 19 to CPU1, and SW is 16H.
Buzzer BZ of incoming signal detected by z detection circuit 19
Is a switch for controlling the output to.

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 the ringing tone and goes off-hook, the contact of the hook switch HS2 is closed and the transistor Q1 is turned on to close 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.

If the exchange connected to the outside lines L1 and L2 can receive the incoming call signal of 16 Hz and the telephone number of the other calling party when the incoming call is received,
Such a caller telephone number can be received on the device side via the modem 18, as described above. 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.

On the other hand, among the incoming calls coming to the outside lines L1 and L2, there are incoming calls necessary for the user.
There is an incoming call that the user does not want to answer or an annoying call resulting from a prank call, and the user cannot identify these in advance.Therefore, answer the prank call or answer the necessary call. There is a situation where it does not exist. Therefore, the present apparatus identifies whether or not this incoming call is a mischievous incoming call before answering the incoming call by using the above-mentioned caller telephone number so that only the necessary incoming call can be answered.

FIG. 2 shows the CPU of such an answering machine.
3 is a flowchart showing the operation of No. 1. The main operation of the present invention will be described in detail according to this flowchart.
First, the caller telephone number registration operation shown in FIG. 2A will be described. When the CPU 1 is activated, it executes an initialization process in step S1. Then, after the completion of the initial setting process, the CPU 1 executes various processes.
In this example, it is assumed that the outside call processing is executed in step S2. The outside line call processing includes the outside line incoming call answering call processing described above when the answering machine is not set in the device, and the outside line outgoing call processing for calling the outside lines L1 and L2 and making a call according to the other party's response.

After the outside line call processing in step S2, the CPU 1 determines in step S3 whether or not the outside line is opened after the outside line incoming response call. Here, if it is assumed that the user goes off-hook while receiving an outside line to make an outside-line incoming response call, and after this ends, opens the outside lines L1 and L2 by on-hook, the determination in step S3 becomes “Y”. In such a case, the CPU 1 sends the registration key 17 in step S4.
When it is determined whether or not A is pressed, and when the registration key 17A is pressed, the process proceeds to step S5, and the telephone number of the calling side (that is, the call origination) during the outside line incoming response call processing performed in step S2. Person telephone number) is registered in a predetermined area of the memory 13.

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. When the caller telephone number is input from the modem 18, the CPU 1 temporarily stores it in a separate area of the memory 13 and restores the relay RY. If 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. Once stored in a separate area.

After that, when the user answers the incoming call and makes a call, and the call ends and the user goes on hook, the outside line L1,
L2 is opened. If the user determines that the answering call is a prank call and operates the registration key 17A, the caller telephone number temporarily stored in a separate area of the memory 13 is registered in a predetermined area of the memory 13. . The caller telephone number registered in this way is as described below.
At the next incoming call, the caller telephone numbers coming from the outside lines L1 and L2 are collated, and if they match, the answering outside lines L1 and L2 are immediately opened in response to the incoming call, and repulsion processing for the mischievous call is performed.

If the user does not operate the registration key 17A after the call for answering an incoming call to the outside line, it means that the current call was not a prank call but a normal call with the other party. Other processing is executed in step S6 without performing registration. Also, step S2
The outside line call processing executed in step S3 is not related to the outside line incoming call answering line, but is related to the outside line outgoing call, and accordingly, the step S3 is performed.
If the determination is “N”, the CPU 1 similarly executes other processing in step S6.

As described above, in the present embodiment, since the caller telephone number is registered by operating the registration key after the incoming call response to the outside line, for example, the exchange side may register this number to reject the incoming call. Compared with the case, there is an effect that a caller telephone number can be registered immediately and a registration fee is unnecessary. In this embodiment, the caller's telephone number is registered after the outside line incoming response call is finished, but it may be during a call or during a call. Further, the user can register in advance by operating the dial key 16 at an arbitrary timing. The caller telephone number registered in the memory 13 can be deleted by operating a key (not shown) in the function key 17.

Next, FIG. 2B is a flow chart of the CPU 1 showing the repulsion operation of the above-mentioned prank call. C
When the PU1 is activated, it executes an initial setting process in step S11. After completion of this initial setting process, the 16 Hz detection circuit 1 detects whether there is an incoming call coming to the outside lines L1 and L2.
In step S12, the external line incoming call detection determination that is detected via 9 and the photocoupler PC is performed. If the outside lines L1 and L2 are ISDN lines, the outside line incoming detection determination of step S12 is performed in a predetermined incoming call protocol process.

If an incoming call to the outside line is detected, the CP
U1 drives the relay RY to close its contact, receives the caller telephone number, which is the calling side of the outside line incoming, through the contact of the relay RY, the transformer T, the modem 18, etc., and receives the received call. The caller telephone number is matched with each caller telephone number registered in the memory 13. In addition, the outside line L
When 1 and L2 are ISDN lines, the calling party telephone number included in the calling address sent from the exchange side is received, and the matching with the calling party telephone number in the memory 13 is performed.

When the received caller telephone number and the caller telephone number registered in the memory 13 match and the judgment of "External call prohibition number?" In step S13 is "Y", the CPU 1 In step S14, the transistors Q2 and Q1 are turned on to close the DC loops of the external lines L1 and L2, thereby capturing the external lines. As a result, an automatic response to an incoming external line is made. After such an automatic response to an incoming external line, the CPU 1 immediately executes the external line opening process of turning off the transistors Q2 and Q1 in step S15 to open the loop of the external lines L1 and L2, and proceeds to step S16 to perform other processes. . When the outside lines L1 and L2 are ISDN lines, each message is exchanged with the exchange side in each protocol process, whereby the incoming call response in step S14 and the outside line release in step S15 are performed.

As described above, when the caller telephone number received at the time of the incoming call matches the caller telephone number of the memory 13, the CPU 1 judges that this incoming call is a mischievous incoming call, and automatically captures the outside line of the incoming call. In addition to automatically answering an incoming call, the captured outside line is controlled to be immediately opened. As a result, the prank call can be effectively repelled. In the case of an incoming call due to such mischief, the CPU 1 controls the switch SW so that the buzzer BZ does not ring the ringing tone by driving the switch SW to open its contact. Also, the received caller telephone number and memory 1
The caller's telephone number registered in 3 does not match, and step S
If "N" is obtained in step 13, after performing other outside line incoming processing (normal outside line incoming processing) in step 17, the process proceeds to step S16 and other processing is executed.

In this embodiment, if the "external line incoming call prohibition number?" In step S13 is determined to be "Y" and the incoming call is recognized as a mischief, the external line is immediately opened after the incoming call is answered. However, it is also possible to send a predetermined message or tone recorded in the recording / reproducing IC 8 after the incoming call is answered, and then to open the outside line. That is, when it is determined that the "external line incoming call prohibition number?" In step 13 is "Y", the external line is captured and the incoming call is answered in step S14. After that, the CPU 1 controls the voice recording / reproducing circuit 7, and the voice message “unable to connect” recorded in the recording / reproducing IC 8 or the annoying “beep” sound is recorded in the voice recording / reproducing circuit 7, the amplifier 9 and the communication circuit. Outer line L via 6 etc.
1 to L2 side. When the transmission of these is completed, the outside line is opened in step S15.

In this way, by sending the voice message "unable to connect" to the calling side, the calling side can be made aware that it is useless to make a prank call. In addition, by sending an offensive "beep" sound, the calling side can be made uncomfortable, and as a result, it is possible to prevent the calling side from making another prank call. Therefore, the prank call can be repelled more effectively. In addition, although an example of the answering machine is described in the present embodiment, it is obvious that the same can be applied to a single telephone and a button telephone, and the same effect can be obtained in these cases.

[0027]

As described above, according to the present invention, the caller telephone number sent from the exchange together with the incoming signal is registered based on a predetermined operation, and the caller telephone number received at the time of incoming call is registered. When a match with the caller's telephone number is detected, the telephone line is temporarily captured and then the captured telephone line is opened, so that the user can receive this incoming call if it is an unnecessary incoming call such as a prank call. By registering the above-mentioned calling party telephone number of the originating side, the mischievous telephone or the like can be immediately repelled from the next incoming call, so that it becomes possible to answer only the necessary incoming call. Also, if the registered caller's telephone number and the received caller's telephone number match, the telephone line is captured, a message is sent to this telephone line, and then the telephone line is opened. It is possible to effectively repel unnecessary incoming calls caused by telephone calls and the like.
