ABSTRACT:
In an input pen having a pen-shaped casing, a ferrite core with a coil wound thereon and a ferrite chip are placed opposed to each other with an O-ring therebetween. The ferrite chip has a projection. When the input pen is operated, the projection and the ferrite core are moved closer together. When the ferrite chip is moved closer to the ferrite core during operation, the projection is placed substantially close to the ferrite core. Therefore, high responsivity is ensured without moving the ferrite chip into the coil, and there is no need to form an opening or a cavity in the ferrite core.
