A. Phone Configuration

As shown in Fig. 1, the telephone of the present invention includes the following additional components in a conventional telephone.

The telephone of the present invention includes a memory button 16 for registering a telephone number of a specific destination in a memory and a DEL button 14 for deleting a registered telephone number stored in the memory.

In addition, a circuit portion having a block diagram as shown in FIG. 2 is incorporated in the telephone main body 20 of the present invention.

The telephone of the present invention includes a CPU 21, a key input unit 24, a dial circuit 23, a speech circuit 22, a tone detection unit 28, a hook switch 27, a speaker phone button 31, a flag. (26), memory (25), speaker (29), and microphone (30).

The CPU 21 receives a key input signal to control dialing, stores a telephone number of a specific destination in the memory 25, and controls to automatically dial the stored number when the handset or speakerphone button is operated. Generate various display control data.

The key input unit 20 includes a plurality of numeric buttons for generating a dial signal, inputs the CPU 21 to the CPU 21 when the dial data is generated, and displays a data under control of the CPU 21. Equipped.

The memory (hereinafter, the relative number storage memory) 25 stores a telephone number of a specific destination, and accesses or stores a dial number under the control of the CPU 21.

Here, the telephone number (or relative number) of the specific destination means the telephone number of the specific counterpart registered by the user. For example, when a housewife suddenly goes out of business at home, it means a phone number where a child can come home and contact him in kindergarten, a phone number he frequently contacts, or a phone number of a specific service provider such as 080. .

The relative number may be fixed at all times, may be changed periodically, or may be changed according to a user's intention. The procedure for registering and correcting the relative number is easily understood by referring to the flowchart of FIG.

The flag 26 is a condition code for representing the storage state of the relative number storage memory 25. That is, if the relative number is registered in the relative number storage memory 25, it is set to '1'. If the relative number is not stored in the relative number storage memory 25, it is set to '0'. Here, registration means a state in which the relative number is stored in the relative number storage memory.

Call initiation detecting means such as the hook switch 27 and speakerphone button 31 are operated when the user starts a call to notify the CPU 21 of the start of the call.

The hook switch 27 is connected to the operation of the hook 15 of FIG. 1 so that when the user lifts the handset 11 for a call, the hook is released and is turned on.

The speakerphone button 19 is a button which is operated when the user wants to talk while the user does not pick up the handset. Like the hook switch 27, the speakerphone button 19 notifies the CPU of the start of the call.

The dial circuit 23 performs dialing of the number under the control of the CPU 21.

The tone detector 28 detects a dial tone input to a line of a public switched network (PSTN) or a key phone system and transmits it to the CPU 21.

The speech circuit 22 forms a call path under the control of the CPU 21, processes a voice signal input from a tip and a ring terminal, and outputs a voice signal to a speaker or a voice input from a microphone. The signal is processed and sent to the Tip and Ring terminals.

Therefore, the CPU 21, the dial circuit 23, the speech circuit 22 and the like read the relative number from the relative number storage memory 25 and automatically dial the dial signal based on the read telephone number data. Automatic dialing means for generating and sending to the exchange.

The remaining unreferenced symbols 29 and 30 represent the speakers and microphones included in the handset.

B. Registration Process of Relative Number

3 is a flowchart illustrating a process of registering a telephone number of a specific destination in the telephone of the present invention.

Hereinafter, a process of registering a relative number in the telephone of the present invention will be described in detail with reference to FIG. 3.

First, the user presses the memory button 16 attached to the main body of the telephone. (S11)

When the user presses the memory button, the CPU checks the flag to see whether there is a relative number registered in the relative number storage memory. (S12)

At this time, if the flag is set to '0' (when a relative number is not registered in the relative number storage memory), the CPU displays the message 'Enter the other's telephone number' on the display.

After confirming the message, the user enters the telephone number of the specific destination to be registered by using the numeric keys and presses the # key. (S15)

When the input of the # key is confirmed, the CPU stores the relative number in the relative number storage memory (S16) and sets the bit of the flag to '1'. (S17)

On the other hand, if the flag is set to '1' in S12 (relative number is registered), the CPU reads the registered telephone number from the storage memory and displays it on the display.

When the registered phone number is displayed, the user decides whether or not to modify the displayed phone number (S13). When the phone number is corrected, the old phone number is deleted by using the DEL key 14, and a new phone number is entered. Perform registration correction mode. (S14)

C. Auto Dialing Procedure

4 shows a procedure for automatically transmitting a dial signal corresponding to a telephone number of a specific destination using only the handset by using the telephone of the present invention.

When the user picks up the handset, the hook pressed on the handset is lifted and the hook switch associated with the hook is turned on. (The operation of the speakerphone button, which plays the same role as the handset, is also regarded as the same as the conduction of the hook switch.)

The CPU of the telephone of the present invention checks whether the hook switch or the speakerphone button has been operated (S21), and checks the status bit of the flag when the dial tone is dropped from the telephone exchange. (S22)

At this time, if the status bit of the flag is set to '1' (S23), the relative number registered in the relative number storage memory is read. (S24)

When the reading of the relative number is completed, the dial pulse corresponding to the relative number is applied to the dial circuit to automatically send out the dial signal corresponding to the relative number. (S25)

On the other hand, if the status bit of the flag is set to '0' in S23, the normal manual dial mode is performed. (S31)

Here, the conventional manual dial mode refers to a mode in which a user picks up a handset and confirms a dial tone and then attempts to make a phone call with the other party by touching a phone number button.

D. Industrial Applicability

In the case where the telephone of the present invention is applied to the industry, (1) a random telephone number is automatically transmitted (when mainly used for home use), and (2) commercial fixed numbers stored by existing 080 operators It can be divided into the case of automatic transmission by inputting.

(1) Use at home

The telephone number to be automatically transmitted can be entered or deleted by the user on his / her own phone. Therefore, if you register the phone number of the destination when you go out for urgent business, even if another user does not know the phone number of the other party just by picking up the handset will be automatically connected to the registered number will be able to talk easily.

For example, when a housewife suddenly goes out for business at home, a child (a child who is poor at entering a phone number) comes in when she registers a contact number of a place to go to the telephone of the present invention and goes to work as a destination of the registered number. Even if you don't enter a phone number, you will be automatically connected to the housewife's place as soon as you pick up the handset.

In addition, it can be very difficult for a disabled person to enter a phone number. In some cases, even pressing a shortcut button will be difficult. However, if you register a phone number that is frequently contacted to the phone, it is possible to connect the call without difficulty entering the phone number because the handset is connected without a difficult dial operation.

(2) usability as commercial

One of the features of the existing 080 vendors is the one-touch dial function connected to the phone outside the phone. However, the press itself is often forgotten or uncomfortable because of the low frequency of use, and there are various problems in the widespread utilization.

The telephone of the present invention has a phone number for 080 vendors, so they can enter the number of 080-***-**** and the customers are connected only by the operation of the handset and the speakerphone button. Will be

For example, if you are a company of Hantong Information System or Hantong Multimedia, which listens to the current 15-second commercial and uses local and long distance calls for free, the external speed dial machine (PD) It is attached to the outside of the phone and picks up the handset and presses the PD to connect to the company's system and listen to the advertisement.

However, in public offices and general businesses (cafes, car repair shops, banks, inn rooms, PC rooms, karaoke rooms, and testimonials), the users are mainly customers, so there are no customers who deliberately press the shortened PD, so they cannot easily join the store. Lie in reality.

However, when you enter the phone, the automatic connection is made at the time of picking up the handset, so it can be used anywhere and in terms of securing members, which will bring the best success. In addition, the company is expected to get a great response from the cost savings of businesses.

(3) Application in public institutions

If you install a regular phone on the street to perform public service, everyone will come and use it. However, if the phone is set to fix the input phone number so that it cannot be changed, the phone is connected only to the stored number, so there is no need to worry about other phone costs.

If you use the telephone of the present invention in the police to operate a free counseling phone for the problem of youth these days, the telephone number (phone number of the counseling office) registered in the present invention phone, even if installed anywhere, it is impossible to use for other purposes Youth use will also be high.

In addition, since it is similarly possible to operate according to the situation in each region, the use of the present invention phone may be utilized in various ways in homes, businesses, and public institutions.

The present invention is not limited to the above-described embodiments, and various modifications and variations are made by those skilled in the art within the equivalent scope of the technical concept of the present invention and the claims to be described below. Of course it is possible.

The telephone of the present invention can be easily called because the telephone is automatically connected to the destination at the moment of picking up the handset even when the number is difficult or difficult to use.

In addition, since the user can input the number himself, he / she can store any number and talk.
