Abstract

PROBLEM TO BE SOLVED: To obtain a telephone set with bell cut-off button by which the transmission telephone number coming from a telephone line can be visually discriminated whether the number is one registered in the telephone set or not by the color of an incoming call display. SOLUTION: When an incoming call signal comes from a telephone line 1, the signal is detected by an incoming call detection part 2, which outputs the detected signal to a CPU 3. In response to the reception of the detected signal, the CPU 3 transmits a response signal from a speech circuit part 9 to the telephone line 1. Next, the transmission telephone number coming from the telephone line 1 is detected by a transmission telephone number detection part 4 and the detection output is outputted to the CPU 3. The CPU 3 stores the received transmission telephone number in a storage part 5 and displays it on a display part 7 and generates ringer sound from a ringing part 6 in response to the call signal. The received transmission telephone number and a preliminarily registered transmission telephone number are compared with each other. When equality is obtd. blue light blinking is performed on the display part 7, and when inequality is obtd. the incoming display of red light blinking is performed. In the case of the incoming call does not contain the transmission telephone number the display of orange color blinking is performed. By a bell cut-off button, a trouble due to ringer sound is eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention changes the color of a call display depending on whether or not a calling telephone number arriving at a telephone through a telephone line is registered in a telephone storage unit, and further, when a call is judged to be unnecessary, a call can be made. Relates to a telephone with a bell-cut button characterized by stopping ringing sound.

[0002]

2. Description of the Related Art Conventionally, an ISDN digital telephone network has a function of ringing an incoming call and displaying a caller's number. In the United States and the United Kingdom, the telephone number of a general analog telephone network is notified to a telephone. A calling number notification service is provided. In this service, if the calling telephone number displayed on the display of the telephone does not want to answer if it is the other party, the telephone keeps ringing until the caller abandons the call. It was Therefore, a method has been proposed in which the calling telephone number is not ringed from the beginning unless it is registered in the telephone.

[0003]

However, there are many telephones that want to answer even if they are not registered. Therefore, if it is possible to stop the ringing sound when it is found that the phone is an unnecessary telephone, the ringing sound will not bother the user. An object of the present invention is to visually know what kind of caller the user is before answering, and to stop ringing with one touch without answering for a telephone that is judged not to answer. It is to provide a telephone with a bell-cut button having a function capable of performing.

[0004]

In order to achieve the above object, the present invention has the following structure. Storage means for storing a first calling telephone number, detection means for detecting a second calling telephone number coming from a telephone line, and second detecting means.
The display means for displaying the calling telephone number of No., the comparing means for comparing the second calling telephone number coming from the telephone line with the first calling telephone number stored in the storage means, and the comparison means for comparing A telephone with a bell-cut button equipped with means for changing the color of the blinking indicator when ringing when it matches and when it does not match, and for stopping the generation of ringing sound in response to a ringing signal.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a flowchart of the operation of the telephone of the present invention. FIG. 2 is a block diagram of an answering machine for identifying a calling telephone number according to the present invention. 1 is a telephone line, 2 is a telephone line 1
An incoming call detecting unit for detecting an incoming call signal coming from the telephone, a control unit (hereinafter referred to as a CPU) for performing various controls, and a calling telephone number detecting unit for detecting a calling telephone number which is a modem signal coming from the telephone line 1. Reference numeral 5 is a storage unit that stores the calling telephone number and the like, 6 is a ringing unit that outputs a ringing sound, 7 is a display unit that performs a blinking display operation and a calling telephone number display when receiving a call, and 8 is a registration operation and the like. An operation unit, 81 is a bell cut button for stopping the ringing sound, and 9 is a call circuit for making a call through the telephone line 1.

First, the operation will be described with reference to FIGS. When an incoming call signal arrives from the telephone line 1 to the telephone, the incoming call detector 2 detects it and outputs a detection output to the CPU 3. CP
In response to this, U3 returns a response signal from the call circuit unit 9 to the telephone line 1. Then, the outgoing telephone number coming from the telephone line 1 is detected by the outgoing telephone number detecting unit 4, and the detected output is sent to the CPU 3
To put out. That is, the outgoing telephone number, which is a modem signal, reaches the modem 14 via the capacitor 41, the transformer 42, and the amplifier 43. The modem signal of the calling telephone number is demodulated into a digital signal and input to the CPU 3.

The CPU 3 stores the incoming calling telephone number in the storage unit 5 and displays it on the display unit 7, and causes the ringing unit 6 to generate a ringing sound in response to the calling signal. Next, the calling telephone number that has arrived and the calling telephone number that is registered in advance are individually compared. If they match, the CPU 3 causes the display unit 7 to
The incoming call blinking in blue is displayed. If they do not match, the incoming call is displayed in red flashing.

When the incoming telephone number does not arrive from the telephone line 1, a blinking orange color is displayed on the display unit 7 and a normal ringing operation is performed.

Next, when the called party who hears the ringing sound tries to answer the telephone and looks at the telephone, the blinking color indicates whether the incoming call is from the telephone with the registered telephone number, and Specifically, the calling telephone number of the calling party displayed on the display unit 7 can be known. Depending on the situation of the called party, for example,
If the called party receives a call while talking to an important visitor, press the bell-cut button on the telephone immediately to blink red or orange. Then, the CPU 3 having received this deactivates the ringing unit 7. This stops the ringing. If it is blinking in blue, the calling telephone number displayed on the display is checked. If absolutely necessary, the handset can be picked up and answered, but if it is judged that it is possible later, the bell cut button is pushed. This operation is similar to that described above, and the CPU 3
Makes the ringing section 7 inoperative. Therefore, the ringing stops.

On the contrary, for a call received when the called party has time, if the caller is in the blue flashing display, the calling telephone number displayed on the display section 7 can be confirmed by the blue flashing display. After that, take the handset and respond. When the handset is lifted, the CPU 3 which detects the handset activates the call circuit and establishes a call with the calling telephone through the telephone line 1. On the other hand, if the other party does not want to respond, the bell cut button may be pressed. The pressing of the bell cut button is detected by the CPU 3, and the ringing section 7 is controlled to be inoperative. Then the ringing sound stops.

After the ringing sound is stopped in this way, when the caller gives up the call origination request, the CPU 3 detects this and returns the state of the telephone to the standby state. When a new call signal arrives, the ringing unit 6 is operated again to generate a ringing sound.

[0012]

As described above, in the telephone with the originating telephone number identification according to the present invention, the color of the incoming call display of the incoming call differs depending on whether or not the outgoing telephone number coming from the telephone line is registered in the telephone. Therefore, since the general caller can be visually identified, and since the bell-cut button is provided, there is no need to be bothered by the ringing sound of the telephone that does not want to answer.
