Touch pen, electronic device for recognizing the touch pen, and method of operating the electronic device
First Claim
1. An electronic device including a touch pen, wherein the touch pen comprises:
- a hollow housing;
a coil body disposed in an interior of the hollow housing and comprising a plurality of coil windings;
a magnetic body separated from the coil body; and
a button unit moveably connected to the coil windings and configured to adjust an electrical length of the coil windings, wherein the button unit comprises;
a sliding key button partially exposed to an exterior of the hollow housing and configured to slide in a longitudinal direction of the hollow housing; and
a movable terminal installed protruding from the sliding key button toward the coil body configured to be in contact with the coil windings.

Abstract
An electronic device includes an electromagnetic inductive type touch pen and a pen touch panel for recognizing the touch pen. The touch pen includes a hollow housing having a certain length, a coil body installed in the housing and including a coil wound a plurality of times and having a certain length, a magnetic body installed to be separated from the coil body with a certain interval and inducing the coil body to generate a certain resonance frequency, and a button unit installed to expose a part thereof to the outside of the housing and to be flowable and inducing a variance in the resonance frequency of the coil body by controlling an electric length of the coil wound around the coil body according to an operation of a user.
