Thus, a method of inputting a number of a frequently used communication network using a shortcut key has been used.

However, the conventional phone with a shortcut key is configured to pre-register and use a number of frequently used telephone numbers (phone numbers including network identification numbers or area codes), so there is a limit to the numbers that can be accommodated. Rather, the user needs to know which shortcut key is set to the phone number to be called before performing the speed dial function. Therefore, the user is inconvenient to remember all the phone numbers corresponding to each shortcut key.

In addition, in general, considering that one telephone is provided in one home, the speed dial function of the phone performs a speed dial function for a phone number frequently used by all the family members, for example, a phone number such as a relative's house. In the individual, there is a problem that the function becomes a meaningless function.

Accordingly, the present invention has been made in view of the above circumstances, and by providing a shortcut key for an area code or network identification number which is commonly used, a user inputs a fixed area code or network identification number one by one. The object is to provide a telephone with a speed dial function to avoid the hassle.

In addition, it is an object of the present invention to provide a telephone with a speed dial function capable of displaying the number data set on a plurality of shortcut function keys, thereby avoiding the inconvenience of storing the number data set on the shortcut function keys.
