DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device for detecting an incoming call on a telephone line and notifying the user of the incoming call.

[0002]

2. Description of the Related Art In an answering machine, as is well known,
When an incoming call is received during the absence mode, the system automatically answers the incoming call and records a message for the calling party. And when recording the business message, the time at that point is memorized,
Some messages have a function called a time stamp for displaying the recording time of the message using an audible or visible means when the message is reproduced. In such a case, it is convenient for the user of the device to be able to recognize the time and minutes of the call from the other party, but if it is necessary to make a call to the other party, the telephone number of the other party must be used. Is checked and a dial operation is performed to call the other party. Also, in a case where a general telephone makes a call in response to an incoming call, goes on-hook at the end of the call, and then makes a call to the same party again, similarly, the other party's telephone number is checked and dialing is performed. I have.

[0003]

As described above, the conventional answering machine has a time stamp function which is convenient for the user, but this time stamp function is a function which is activated when a call is answered. Therefore, there is a disadvantage that a call charge is required on the calling side to realize this function. Further, if the caller ends the call without transmitting the message, the user of the device cannot recognize who called the telephone, and in this case, there is a disadvantage that the call cannot be sent to the other party. In addition, when a call is re-sent to the same party after the end of an incoming call on a general telephone or the like, there is another problem that the user has to check the phone number of the other party and perform a dial operation, which is troublesome.

Accordingly, the present invention makes it possible to identify an incoming call received during absence and to make a call to such an incoming call and to make a call to the same party again after the end of the answering call. It is an object of the present invention to make it possible to make a call without checking the other party's number, and to record the time of the incoming call and the information of the calling side at this time without responding to the incoming call, thereby reducing the calling charge of the calling side.

These are function keys including an end key 17D, an answering key, not shown, a playback key, and the like.

Reference numeral 18 denotes a modem, and external lines L1, L
When an incoming call arrives at 2, a caller telephone number, which will be described later, transmitted from the exchange together with the incoming call signal is relayed by RY,
CPU that receives via capacitor C2 and transformer T
1 is transmitted. Reference numeral 20 denotes a telephone directory memory, in which a plurality of destination telephone numbers to be called and their names are registered in association with each other. Note that HS1 is a hook switch, PC is a photocoupler that transmits an incoming signal detected by the 16Hz detecting circuit 19 to the CPU 1, and SW is a switch that controls output of the incoming signal detected by the 16Hz detecting circuit 19 to the buzzer BZ. is there.

When the answering key in the function keys 17 is operated, the answering mode is set in the apparatus.
When an incoming call arrives at the accommodated outside lines L1 and L2 during the absence mode, the incoming signal is transmitted to the CPU 1 via the 16 Hz detection circuit 19 and the photocoupler PC. In this case, the CPU 1 controls the transistor Q via the dial circuit 2.
2 to turn on the transistor Q1,
The DC loops of the external lines L1 and L2 are closed to respond to an incoming call.

Thereafter, the audio recording / reproducing circuit 7 is driven and the recording / reproducing I is performed.
The response message recorded in C8 is transmitted to the external lines L1 and L2 via the voice recording / reproducing circuit 7, the amplifier 9, the communication circuit 6, and the like. In response to the transmission of the response message to the calling side, the message from the calling side arriving at the external lines L1 and L2 is recorded on the recording / reproducing IC 8 via the communication circuit 6, the amplifier 9 and the voice recording / reproducing circuit 7. The message on the calling side recorded in the recording / reproducing IC 8 is emitted from the speaker SP via the voice recording / reproducing circuit 7 and the amplifier 9 when a reproduction key (not shown) among the function keys 17 is operated.

On the other hand, if the answering mode is not set in the apparatus, the apparatus operates as a normal telephone apparatus.
That is, when an incoming call arrives at the accommodated external lines L1 and L2 due to a call to the present apparatus on the calling side, the incoming signal becomes 1
The signal is sent to the buzzer BZ via the 6 Hz detection circuit 19 and the switch SW whose contact is normally closed, and the buzzer BZ emits, for example, a ringing sound of 1 second on and 2 seconds off. When the user of the apparatus notices the ringing and goes off-hook, the contact of the hook switch HS2 is closed and the transistor Q1 is turned on to close the DC loop of the external lines L1 and L2. A response to the incoming call is made by closing the loop of the outside lines L1 and L2, and the outside line incoming call with the calling side of the user is realized.

By the way, if it becomes possible for the exchange connected to the external lines L1 and L2 to transmit the telephone number of the caller of the other party together with the incoming signal of 16 Hz to the receiver at the time of the incoming call, such a caller's telephone number becomes The device can receive the data via the modem 18 as described above. When the external lines L1 and L2 are ISDN lines, the caller's telephone number is included in the calling address and transmitted from the exchange, and the CPU 1 executes predetermined protocol processing to receive the caller's telephone number. it can.

On the other hand, the conventional answering machine has a time stamp function for automatically answering the incoming call when answering and recording the time when recording the other party's business message. The time stamp function is a function that is activated when an incoming call is answered, and has a problem that a call charge is required. Also, when making an outgoing call for an incoming call while absent, or when the user himself / herself re-calls the same party after answering the incoming call, the user himself looks up the phone number of the other party and dials. There is also a problem that must be performed. For this reason, the present apparatus makes it possible to make a call without checking the other party number by using the above-mentioned caller telephone number, for example, when making an outgoing call for an incoming call while away from home.
The time of the incoming call and the information of the calling side can be recorded without responding to the incoming call, so that the calling charge of the calling side can be reduced.

FIGS. 2 and 3 are flowcharts showing the operation of the CPU 1 of such an answering machine. The operation of the main part of the present invention will be described in detail according to this flowchart. First, the caller telephone number registration operation shown in FIG. 2 will be described. When started, the CPU 1 executes an initial setting process in a step S1. After completion of the initial setting process, the CPU 1 executes various processes. In this example, in step S2, the outside line incoming call detection determination process is executed.

When an incoming call to an outside line is detected, the incoming signal reaches the buzzer BZ via the 16 Hz detection circuit 19 and the switch SW, and a ringing tone is emitted from the buzzer BZ in step S3. In this case, the CPU 1 registers the caller telephone number received via the modem 18 in the external call history area in the memory 13 in step S4. That is, the outside line L
In the case where 1, L2 is an analog line, the caller's telephone number is switched from the exchange side at the time of an incoming call, for example, the incoming signal is turned off for 2 seconds between the ON of the first 16 Hz incoming signal and the 1 second ON of the next 16 Hz incoming signal Is sent during In this case, the CPU 1 detects the first incoming signal of 16 Hz via the 16 Hz detecting circuit 19 and the photocoupler PC, and drives the relay RY when the first incoming signal disappears to close its contacts and close the external lines L1, L2. To form an AC loop.

Then, the caller's telephone number from the exchange via the external lines L1 and L2 is received by the modem 18 via the contact of the relay RY, the capacitor C2 and the transformer T.
It is transmitted to PU1. When the caller's telephone number is input from the modem 18, the CPU 1 registers the caller's telephone number in the outside call history area of the memory 13. At this time, the CPU 1
5, the current date and current time are read out and registered as reception date and time information of this number corresponding to the caller telephone number, and then the relay RY is restored. The outer lines L1 and L2 are IS
In the case of the DN line, the CPU 1 executes a predetermined incoming call protocol process with the exchange to receive the caller telephone number transmitted from the exchange and included in the calling address, It is registered together with the current date and time information from the clock unit 15.

Thereafter, in step S5, the CPU 1 detects the state of the hook switch HS1 to determine whether or not an off-hook operation has been performed. If an off-hook operation has been detected, the hook switch HS2 associated with the hook step HS1 is closed. As a result, an incoming call is made by the user in step S6. Also, in the case of an ISDN line, a transition to an incoming call is made by executing a predetermined protocol. During such an incoming call, the CPU 1
Measures the talk time and monitors the state of the hook switch HS1 in step S7 to determine whether the user has gone on-hook. When the on-hook is detected, the call time required for the incoming call is registered in step S8 in accordance with the caller's telephone number in the outside line call history area and its date and time, and step S9 is performed.
After performing the other processing, the process returns to step S2 to detect the next incoming call.

If the on-hook of the user is not detected, outside line communication processing other than the registration of the outside line talk time is performed in step S10. If the off-hook is not detected at the time of the incoming call, the process proceeds to step S11, and the incoming call is determined again via the 16 Hz detection circuit and the photocoupler PC. When the calling side abandons the call before responding to the incoming call, the outside lines L1, L
2, no incoming signal arrives, so step S1
When the "outside incoming call end" of "1" becomes "Y", step S9 is executed.
After the process proceeds to step S2 and returns to step S2, the next incoming call is detected. If the incoming call continues and the “outline incoming call end” in step S11 becomes “N”, other outside line incoming processing is performed in step S12.

In this way, when an incoming call to an outside line is made, the caller's telephone number transmitted from the exchange side is sequentially registered in the outside line call history area of the memory 13 together with the reception date and time information, and the user responds to the call. Is to register the call time in association with each caller's telephone number. Therefore, when making a call to the incoming call (calling side) while absent or when redialing to the other party who made the answering call, the call can be made based on the registered caller telephone number. In this case, it is possible to make outgoing calls without checking the other party's number, and to record the time of incoming calls and the calling party information (caller phone number) at that time without answering the incoming calls. It is possible to reduce the calling charge of the calling side.

This apparatus has the above-mentioned telephone directory memory 2
0 is provided. By comparing the telephone number in the telephone directory memory 20 with the above-mentioned caller telephone number, when registering the caller telephone number, the telephone number is stored in the telephone directory memory 20 together with the caller telephone number. Can be registered. That is, when registering the caller's telephone number in the outside call history area of the memory 13 in step S4, the caller's telephone number is compared with each telephone number registered in the telephone directory memory 20, and a match is found. judge. If they match, the information such as the name registered in correspondence with the matched telephone number in the telephone directory memory 20 is registered in the outside call history area of the memory 13 together with the caller telephone number. The caller's telephone number and its name information registered in this way are then used as described later to retrieve the caller's telephone number and make a call when a call is made to the display 14 by a predetermined operation.
, So that the call can be sent to the other party without fail.

Next, the operation of the CPU 1 for making a call based on the caller telephone number sequentially registered in the outside call history area of the memory 13 will be described with reference to the flowchart of FIG. When started, the CPU 1 executes an initial setting process in a step S21. Then, after the end of the initial setting processing, it is determined in step S22 whether or not the call history display key 17A in the function key 17 has been pressed. Here, when the call history display key 17A is pressed by the user of the device,
In step S23, the CPU 1 sequentially reads out the caller telephone number registered in the outside line call history area of the memory 13, the reception date and time, and the call time, and displays them on the display 14.
If the caller's telephone number matches the telephone number in the telephone directory memory 20 and, therefore, the name information is also registered in the external call history area, the name information is also displayed on the display 1.
4 is displayed.

While the caller's telephone number is being displayed on the display 14, the user presses the cursor key 17 of the function keys 17.
When B is pressed, the determination in step S24 becomes "Y". In this case, if the display 14 is a large display and the caller's telephone number and its reception date and time can be displayed in a plurality of columns, the caller's telephone number in the next column can be displayed. Blinks. Display 1
If only 4 can be displayed in one line, the process returns to step S23 to read out the next caller's telephone number and the like from the outside call history area and display it on the display 14.

In this way, the caller telephone numbers to be transmitted are sequentially selected and displayed on the display 14. Then, when the caller telephone number to be transmitted is determined and the transmission key 17C is pressed by the user, the determination in step S25 becomes "Y". Therefore, the CPU 1 determines in step S26 the selected and determined caller telephone number. Performs an outside line automatic call based on the number. That is, in this case, the CPU 1 turns on the transistors Q2 and Q1 via the dial circuit 2, thereby turning on the external lines L1 and L1.
Close the DC loop of L2. Next, the CPU 1 sets the determined caller's telephone number to the dial circuit 2 sequentially one digit at a time, so that the dial circuit 2 outputs a dial signal corresponding to the caller's telephone number to the captured outside lines L1 and L2. I do. Then, after the completion of the automatic dialing, the process shifts to step S27 to perform other processes, and then returns to step S22.

When the caller key 17C is not operated and the end key 17D is depressed while the caller telephone number or the like is displayed on the display 14, and the judgment in step S28 is "Y", The process proceeds to step S27 without performing the outside line automatic transmission, and executes other processes. In this way, when an outside line is received, the caller's telephone number transmitted from the exchange is registered along with the date and time of reception, and when making an outgoing call in the absence mode, When a call is made again, the registered caller's telephone number is read and displayed on the display 14, and the call is made by operating the call key 17C. As a result, from the incoming call history in which the caller's telephone number at the time of the incoming call is stored, it is possible to easily identify where the call was made from when the user was absent, so that it can be used as a simple answering machine function. Further, by searching and displaying the incoming call history, the searched caller telephone number can be sent as it is, so that it can be used as simple automatic dialing.

In the present embodiment, the caller's telephone number and the like are displayed on the display unit 14. However, if a recording medium such as a printer is provided, it is possible to record on this recording medium. Further, in the present embodiment, the caller's telephone number at the time of an incoming call is stored and the history of the incoming calls is left. Is also possible. Further, in the present embodiment, the example of the answering machine has been described. However, it is apparent that the present invention can be similarly applied to a single telephone and a key telephone, and in these cases, the same effect can be obtained.

[0027]

As described above, according to the present invention, a caller's telephone number sent from the exchange together with an incoming signal is received and stored when an incoming call is received, and stored when a predetermined display operation is performed. Since the caller's telephone number is displayed, the caller's telephone number, which is the telephone number of the calling side, is stored for a call received during absence, for example. This makes it easy to identify who the call is from. Also, since the caller's telephone number can be stored without responding to the incoming call, the calling party does not need to pay a call charge in this case. Further, since the caller telephone number and the reception date information of the caller telephone number are stored in association with each other, it is possible to easily identify when the call is received. Also, since the caller's telephone number is displayed on the display, the caller's telephone number can be displayed easily and economically. Also, when a predetermined selection operation is performed while the caller telephone number is displayed on the display, the telephone line is captured and the selected caller telephone number is output to the captured telephone line as a dial signal. For example, in the case where a call to the same party is again made after a call received while answering and an incoming response call is completed, the call can be easily made without checking the party number. When the received caller telephone number is registered in the phonebook memory, the caller telephone number and the user name are stored in association with each other. Can be transmitted reliably.
