Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device having a function of storing caller telephone number information sent when an incoming call arrives.

[0002]

2. Description of the Related Art At present, ISDN provides a service for transmitting the telephone number information of a caller when an incoming call arrives. Further, as a telephone device connected to the ISDN, a function of storing and displaying a caller telephone number sent when an incoming call is received, and a caller telephone number stored by a predetermined key input operation are displayed and automatically dialed. Some have an automatic dialing function.

Therefore, if the above-mentioned service contract is made by using such a telephone device, it becomes possible to identify the caller from the caller telephone number displayed at the time of receiving an incoming call, and thereby select whether or not to answer. You can
When a call cannot be answered due to absence, etc., a caller telephone number stored for each incoming call can be read out and displayed by a predetermined key operation, and a dial call can be made automatically.

[0004]

However, in the above-described conventional telephone device with a caller telephone number storage function, caller telephone number information is stored for all incoming calls regardless of whether the call is answered or not. I am trying to do it. For this reason, a memory with a large capacity is required as a memory for storing the caller telephone number information, and there is a problem that the cost is high. Further, since unnecessary caller telephone number information is stored as in the case of responding, the memory of the memory is stored. There is a problem of poor utilization efficiency.

The present invention has been made by paying attention to such a conventional problem, and is appropriately configured so that the memory capacity can be reduced and therefore the cost can be reduced and the utilization efficiency thereof can be effectively improved. An object is to provide a telephone device with a caller telephone number storage function.

[0006]

In order to achieve the above object, according to the present invention, in a telephone device with a caller telephone number storing function, the caller telephone number storing function is provided with a storing means for storing caller telephone number information transmitted at the time of incoming call. Setting means for setting the operation mode of the means and control means for controlling the storage operation of the caller telephone number information by the storage means based on the operation mode set by the setting means.

[0007]

In the above structure, the storage means is controlled by the control means in accordance with the operation mode set by the setting means. Therefore, by properly setting the operation mode, for example, the mode in which the storage means is operated only in the desired time zone, it is possible to prevent the storage of unnecessary caller telephone number information for incoming calls outside the desired time zone.

1 shows an embodiment of the present invention. The telephone line 1 to which the other party's telephone number information is sent when receiving a call is connected to the incoming call detection circuit 2, which detects the incoming call and supplies the incoming call detection signal to the controller 3 The telephone number information is supplied to the memory 4. A display 5 and an automatic dial circuit 6 are connected to the memory 4, the destination telephone number information stored in the memory 4 is displayed on the display 5, and the destination telephone number information is detected by the automatic dial circuit 6 by the incoming call detection circuit 2. To be able to dial automatically via.

In this embodiment, setting means 7 is provided in connection with the controller 3, the operation mode of the memory 4 is set by the setting means 7, and the set operation mode and the incoming call detection signal from the incoming call detection circuit 2 are set. Based on the above, the controller 3 controls the storage operation of the destination telephone number information in the memory 4. Further, the destination telephone number information stored in the memory 4 is sequentially read by the controller 3 based on the input information from the setting means 7 and displayed on the display 5, and the displayed destination telephone number information is
Based on the input information from the setting means 7, the automatic dial circuit 6 automatically dials through the incoming call detection circuit 2.
The setting means 7 is composed of, for example, a push button provided in the telephone device.

In this embodiment, the operation mode of the memory 4 set by the setting means 7 is set to a desired one among a non-response storage mode, a designated time zone storage mode and a manual operation storage mode. Thus, when the non-answering memory mode is set, the destination telephone number information for the incoming call is stored in the memory 4 only when the incoming call is not answered, and the designated time zone storage mode is set. Is
When a desired time zone is specified, the telephone number information of the other party is stored in the memory 4 only for the incoming calls within the specified time zone, and when the manual operation storage mode is set, the incoming call is received until the mode is released. The telephone number information of the other party is stored in the memory 4.

As described above, if the storage operation of the caller telephone number information by the memory 4 is controlled based on the operation mode set by the setting means 7, it is possible to effectively prevent the unnecessary storage of the caller telephone number information. Therefore, the utilization efficiency of the memory 4 can be improved, the capacity thereof can be reduced, and the cost can be reduced.

In the above embodiment, the desired mode is set from the non-response time storage mode, the designated time zone storage mode and the manual operation storage mode. However, the non-response time storage mode and the designated time zone storage mode are set. Or, the memory mode when not responding and the manual operation memory mode are combined, and the caller telephone number information is stored only within the specified time period and when there is no response, or only when the memory mode is selected and there is no response. You can also

[0013]

As described above, according to the present invention, it is possible to effectively prevent the storage of unnecessary caller telephone number information.
Since the utilization efficiency of the storage means can be improved and a storage means having a small capacity can be used, the cost can be reduced.
