1. A coordinate input device for use with a tablet, comprising:

  • a casing having a first surface and an opposing second surface, the first and second surfaces being nonparallel; and

    a position-designating member in the casing, the position-designating member and the first surface defining an angle different from an angle defined by the position designating member and the second surface;

    wherein absolute coordinate input is performed when the first surface is placed on a tablet and relative coordinate input is performed when the second surface is placed on a tablet, and wherein said device changes from performing absolute coordinate input to performing relative coordinate input as a result of the physical movement of the casing from having the first surface placed on the tablet to having the second surface placed on the tablet, and said device changes from performing relative coordinate input to performing absolute coordinate input as a result of the physical movement of the casing from having the second surface placed on the tablet to having the first surface placed on the tablet.
