A device for detecting a rotation angle is provided. The device include a first coil, a second coil, and a twist prevention mechanism. The first coil detects a coordinate value. The second coil detects the rotation angle. The second coil includes signal lines extending therefrom. The second coil is rotatable around a center of the first coil without rotating the first coil. The twist prevention mechanism prevents the signal lines from twisting. The device is preferably included in a pack-shaped pointer that operates on a tablet. The pointer and tablet preferably utilize an electromagnetic induction principle to detect the coordinate value and the rotation angle.

Device and method for detecting rotation angle

A coordinate input device (e.g. mouse-like device or cursor-like device) includes an outer housing which is movable between a first position adapted for use by right-handed users, and a second position adapted for use by left-handed users. In such a manner, the coordinate input device is easily utilized by both right and left-handed users. In certain embodiments, a rotatable thumb or finger wheel may be provided in the coordinate input device for manipulation by the user in order to adjust a parameter of an image being written/drawn on a corresponding display screen by the coordinate input device.

Coordinate input device convertible between right-handed and left-handed
