Benefits of technology

[0012] Another object of the present invention is to provide an operation method and operation apparatus of a portable phone in which the number of keys is not increased for a function and a key operation is simple.

Problems solved by technology

Moreover, when multiple functions will be further achieved, it is more difficult to arrange a large number of keys which will increase in accordance to the number of functions.
However, the multiple functions require the user a complicated operation, even if the functions have high use frequencies.

first embodiment

[0033] In the first embodiment, the dial key 2 of “2” and the dial key 2 of “5” are used for a telephone number searching operation. An upward arrow “␣” is attached to the dial key 2 of “2” and a downward arrow “Θ” is attached to the dial key 2 of “5”, as shown in FIG. 2. Thus, the user can easily recognize that the dial key 2 of “2” and the dial key 2 of “5” are used for the telephone number searching operation. It is desirable that the dial key 2 of “2” and the dial key 2 of “5” are formed in special shapes such as a triangle, so that the dial key 2 of “2” and the dial key 2 of “5” can be visually and easily distinguished from the other dial keys 2 by the user.

[0034] Next, referring to FIG. 3, an operation method of the portable phone according to the first embodiment of the present invention will be described. Here, it is supposed that the portable phone is in a dialing operation mode.

[0035] First, it is determined whether the head of a character string or digit string 5-1 input...

second embodiment

[0041]FIG. 6 shows the portable phone according to the present invention. Referring to FIG. 6, the dial keys of “2”, “4”, “5”, “6”, and “8” are unspecific keys. When the dial key of “5 / AG” is first operated as the head of the digit string, the operation mode may be changed from the dialing operation mode to the telephone number searching operation mode. When the dial keys of “2”, “4”, “6”, or “8” is first operated, the operation mode may be changed to another operation mode.

[0042] In the telephone number searching operation mode, the telephone number records are displayed. When the dial key of “2↑”, “4←”, “6→”, or “8↓” is operated, the searching operation of a target telephone number is carried out.

third embodiment

[0043]FIG. 7 shows the portable phone according to the present invention. The portable phone 1′ contains a recording medium 6 which stores a program for the telephone number searching operation. The semiconductor memory is an optimal for the portable phone as the recording medium 6. The processing unit 3′ reads the program from the recording medium 6, and operates the program. The processing unit 3′ executes the same processing as that of the processing unit 3 of FIG. 1.

[0044] According to the operation method and portable phone of the present invention, the retrieval of a telephone number is made quickly possible through only the operation of a dial key. Therefore, any key of exclusive use for the searching operation can be made unnecessary to be provided in addition to the dial keys and the number of parts can be reduced.

[0045] Also, according to the present invention, the operation mode can be changed using the dial key. Therefore, a function can be added without addition of a f...

Abstract

A portable phone includes dial keys including at least one specific key and unspecific keys, and a processing unit. The processing unit determines whether one of the dial keys which is operated in a first mode is one of the unspecific dial keys, and changes an operation mode from the first mode to a second mode when the operated dial key is one of the unspecific dial keys. The portable phone further includes a display unit. In a telephone number searching operation mode as the second mode, the processing unit reads out a list of data associated with destination phone numbers from a storage unit and controls the display unit to display as a non-dialing operation. Also, the processing unit controls the display unit to selectively scroll the list of data in one of upward and downward directions in response to an operation of one of the unspecific dial keys.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an operation method and an operation apparatus of a portable phone, and more particularly to an operation method to change an operation mode by use of a dial key and an operation apparatus of a portable phone for the same. [0003] 2. Description of the Related Art [0004] A small size portable phone has housing formed in a small size. In such a small size portable phone, a key is small and a pitch between the keys is narrow. Moreover, when multiple functions will be further achieved, it is more difficult to arrange a large number of keys which will increase in accordance to the number of functions. [0005] As for the function with a high use frequency such as a telephone number searching operation, the operation needs to be simplified to make it easy for a user to use the function. However, the multiple functions require the user a complicated operation, even if the functions have high ...
