Abstract

A mobile communication terminal capable of selecting a menu or retrieving displayed details in a short time by imparting a directional resolution to a direction operation key. A mobile communication terminal having a function of selecting a displayed menu displayed on a display unit by means of a direction operation key capable of an ominidirectional operation, the terminal comprising a direction detection unit (32) for detecting the operation direction of the direction operation key (3), and a directional resolution control unit (31) for judging an operation direction based on signals from the direction detection unit (32) to select a menu in that direction and displaying it on the display unit (2).

Description

technical field [0001] The present invention relates to a portable communication terminal having a display unit and an operation unit, and more particularly, to a portable communication terminal capable of changing menu selection or display content by operating a direction operation key for a selected direction. Background technique [0002] In a portable communication terminal such as a portable telephone, generally, a display menu is selected by operating a direction operation key in accordance with a display menu displayed on a display portion. Also, when retrieving a map, for example, when retrieving content displayed through a menu display portion, the map is moved. As direction operation keys for such operations, many different types of direction operation keys have been known, such as roller-shaped direction operation keys and direction operation keys having switches provided in four directions. [0003] In the roller-shaped direction operation key, the operation is ...
