ABSTRACT:
The present invention relates to a thin x-y direction input device for moving a cursor on a screen in any direction. The x-y direction input device includes a casing having an opening and an operating member that is resting on the casing and capable of sliding. A cursor appearing on a display moves in any direction according to movement of the operating member. The operating member includes a flat plate sliding over a receiver surface lying in the casing, and a projection that projects from the flat plate and engages with first and second moving members having either detecting elements or elements to be detected, and the projection is exposed from the aperture. This enables smooth movement of the moving members. The operating member is provided with elastic tongues pushing back the first and second moving members from their ends of movement to the center.
