BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone, and more particularly to a mobile telephone suitable for calling a telephone number registered as a telephone directory.

[0002]

2. Description of the Related Art Mobile telephones are expected to expand their use range from business users to personal users, and the telephone number registration function will be improved. If the penetration rate of mobile phones increases, one person will be able to use their business phone number for business,
It is considered that it will have three phone numbers for private use, a home phone number and a mobile phone number.

Further, if faxing is possible from a mobile telephone, even one company needs two telephone numbers for telephone and fax. Furthermore, the function will be improved and personal information such as an address can be input, and the mobile phone will have the function of an address book.

Conventionally, in a mobile phone, a frequently used telephone number is registered together with a name, and by inputting a telephone number or a name registered in advance, it is possible to call a required telephone number with a few button operations. . There are four conventional methods of calling a telephone number: a scroll function, a registration number input function, a name search function, and a telephone number search function. The scroll function method calls the registered numbers in order and registers them. There is a way to call the names that are listed in alphabetical order.

FIG. 4 is an explanatory diagram showing an example of a conventional screen when a telephone number is searched by scrolling in order of registered numbers (memory numbers). FIG. 5 is an explanatory diagram showing an example of a conventional screen when a telephone number is searched by scrolling in the order of registered names.

The method using the registration number input function calls the registration number by inputting the registration number. When the number of registrable items is 0 to 99, the number is 2 digits, and the number of registrable items is 1.
If the number is 00 or more, it will be 3 digits. Here, if the number of registrations increases, it becomes impossible to store the registration number.

The method using the name search function is a method of inputting the first part of the name and calling the registered telephone number and scrolling in the order of Iwayo, or entering the full name and calling the registered telephone number. The input operation becomes difficult.

Further, the method using the telephone number search function is a method in which the registered telephone number is called by inputting the first copy of the telephone number and scrolled in numerical order.

However, in the above-mentioned conventional mobile phone, when the number of registered telephone numbers increases,
Correspondingly, when searching for a target telephone number, there is a problem in that the number of button operations is increased, the operability deteriorates, and the search cannot be performed easily.

The present invention has been made in view of the above situation. Even if the number of registered telephone numbers is increased by adding an index, a desired telephone number can be easily searched with a small number of button operations and a few types of buttons. It is an object of the present invention to provide a mobile phone that can be used.
