Abstract
An input device for moving a cursor to a desired point in a display has a sliding member which moves on a two dimensional coordinate system, a location detector which electrically detects the location of the sliding member within that coordinate system, and a switch to allow data entry in correspondence to the desired point indicated in the display corresponding to the position of the sliding member, in response to depression of the sliding member in a direction perpendicular to the plane of the coordinate system.
