<p>The present invention relates to a coordinate input device that enables coordinates to be input onto the display screens of various types of terminals, such as portable information terminals, through an operation of scrubbing or rubbing two opposite flat plates that are so small that they can be held between two fingers such as the thumb and the index finger or between three fingers, so that it can be easily and stably used even in an extremely restrictive environment such as a narrow space or a mobile situation. The finger mouse-type coordinate input device according to the present invention can detect a signal corresponding to the vertical movement or lateral rotation of two opposite flat plates in response to the application of a drive signal.</p> |
