Problems solved by technology

[0007] However, the ring magnet 1 used in the conventional rotary type input device needs to have multiple N poles and S poles, which not only makes the magnet 1 expensive but also difficult to manufacture
In addition, the magnet 1 forms a magnetic field in its vicinity, which may affect other electronic devices causing damage and malfunction

Abstract

The invention discloses a rotary inputting device, comprising: an annular splint which can rotate and has many salients protruding at a certain pitch at its circumference; a magnet, arranged at the inside or outside of the splint and used to generate magnetic line of force; checking element, arranged on the inside or outside of the splint, facing to the magnet. When the salient is between the magnet and the checking element, the strength of detected magnetic line of force changes. The rotary inputting device does not need magnet with multiple magnetic poles, so it's easy to manufacture and will not influence other electric parts.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2006-0038103 filed with the Korean Intellectual Property Office on April 27, 2006, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a rotary input device. Background technique [0004] Typically, mobile terminals have the numbers 0-9 and the symbols * and # on a 12-key keypad. In addition to these numbers, letters and consonants and vowels of the Korean alphabet are marked on this keyboard, enabling input of information including numbers and letters. Recently, navigation keys formed above the keyboard are also used, equipped with various functions such as telephone number search, writing and managing text information, and connection to the Internet. There are various forms of navigation keys, such as a button type and a rotary type, etc., but since the rotary type inp...
