BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device having a caller's telephone number recognition function.

0002

2. Description of the Related Art Conventionally, telephone devices have been known that are capable of displaying the telephone number of the caller when receiving a call, using a switching center service that sends the caller's telephone number data to the called party along with the incoming call signal. It is being

[0003] With such a telephone device, it is possible to identify who is calling an incoming call before answering the call.

0004

[Problem to be Solved by the Invention] However, in the above-mentioned telephone device, since the telephone number is displayed on the display means, the recipient must remember whose telephone number it is. Another problem is that it takes time to determine who is calling before answering.

[0005]Furthermore, if the phone number of a specific person, such as a close friend or other person you call frequently, is registered in an auto-dial function so that you can automatically dial the phone number with a single touch or a shortened operation, , even when the other party calls, only the phone number is displayed, so
It takes time to determine who is calling, and if you forget that you have registered for automatic dialing or want to call back later, you have to manually dial each time, which is time-consuming. It had some problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone device that solves the problems of the conventional means as described above.

[0007]

[Means for Solving the Problems] To achieve this object, the present invention provides an incoming signal detecting means for detecting an incoming signal coming from a telephone line, and a telephone number of a calling party that comes from the telephone line together with the incoming signal. telephone number detection means for detecting data; storage means for storing a plurality of automatic dial telephone numbers; display means for displaying the telephone numbers; and telephone numbers obtained by the telephone number detection means and stored in the storage means. The telephone device is comprised of a control means for controlling the display means to compare the telephone numbers of a plurality of automatic dials and, if they match, to display a predetermined symbol indicating the automatic dial on the display means.

[0008]

[Operation] According to this configuration, the incoming phone number is
If the telephone number matches one of a plurality of pre-registered automatic dial telephone numbers, it can be displayed with a symbol such as a predetermined number indicating which automatic dial it is.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the main parts of the telephone device, and FIG. 2 is a flow chart showing the operation.

In FIG. 1, 1 is a telephone line, 2 is an interface circuit with the telephone line, 3 is an incoming signal detecting means for detecting an incoming signal coming from the telephone line 1, and 4 is an incoming signal coming from the telephone line 1. Telephone number detection means 5 is connected to a handset (not shown) for detecting an analog signal that indicates the telephone number of the calling party, and amplifies the outgoing signal and sends it to the telephone line 1. 6 is a dial transmitting means for converting dial data outputted from a control means, which will be described later, into a dial signal and transmitting it to the telephone line 1; 7 is a dial transmitting circuit for amplifying an incoming voice reception signal; A display means for displaying the acquired telephone number and a symbol such as a predetermined number indicating that the acquired telephone number is registered in a specific automatic dialing system; The operating section 9 includes a switch to be operated when making a dial call, and is a hook switch. Further, reference numeral 10 denotes a control means for controlling this apparatus, which is constituted by a microcomputer incorporating a RAM of storage means 10a for storing telephone numbers for automatic dialing.

The operation of the telephone device configured as described above will be explained below. A plurality of telephone numbers are registered in advance in automatic dialing using the operating section 8, and the contents of these telephone numbers are stored in the storage means 10a.

[0013] When an incoming signal arrives through the telephone line 1,
An incoming call detection signal is applied from the incoming signal detection means 3 to the input terminal of the control means 10, and the control means 10 detects that there is an incoming call (STEP 1). Further, an analog signal is sent to the incoming signal to inform the calling party of the telephone number, and the telephone number detection means 4 transmits the telephone number data of the calling party to the control means 10.
is input to obtain the caller's phone number (STEP
2). Compare whether the obtained telephone number matches any of the telephone number contents of a plurality of automatic dials stored in advance in the storage means 10a (STEP 3), and if they match, indicate which automatic dial it is in advance. The determined symbol is displayed on the display means 7 (STEP 4). Next, in STEP 3, if no matching telephone number is stored, the obtained telephone number is displayed as is on the display means 7 (STEP 5). At that time, the control means 10 monitors whether the hook switch 9 is off-hook (
STEP 6) When off-hook is detected, the line interface circuit 2 is controlled to close the line (STEP 7),
The transmitting/receiving circuit 5 is controlled to enter a talking state.

Next, the control means 10 controls the hook switch 9
is on-hook and the call ends (
STEP 8) When the end of the call is detected, the interface circuit 2 is controlled to open the line (STEP 9), and the display means 7 is controlled to end the number display (STEP
10).

If off-hook is not detected in STEP 6, the incoming signal detection means 3 monitors whether or not incoming signals continue to arrive (STEP 11).
, when there is no more incoming signal, the process advances to STEP 10 and the display ends.

[0016] From now on, when there is an incoming call, STEP 1
, and repeat the same operation as described above.

[0017]

[Effects of the Invention] As explained above, according to the present invention, it is possible to easily determine who is calling an incoming call, and when making a call back, it is not necessary to dial manually each time. It can be prevented.
