Abstract
This invention relates to a communication terminal device. In order to realize a communication terminal device which improves the operational efficiency and the usability remarkably comparing to a conventional one, an operation key is designed to be rotated, pushed, and slid, and the movement direction or the movement amount of the cursor can be changed when the operation key is slid, so that the cursor can reach at a desired item quickly. As a result, the rotating amount to reach at a desired item can be reduced comparing to a conventional one. Therefore, a communication terminal device which improves the operational efficiency and the usability remarkably comparing to the conventional one can be realized.
