1. An electronic device comprising:
- an input pen comprising at least one pen magnet;
a housing comprising a pen guide path and pen hole into which the input pen is insertable;
a first electromagnet configured to react to magnetism of the at least one pen magnet when the input pen is completely inserted into the pen guide path;
a second electromagnet disposed at a certain distance from the first electromagnet in the outward direction of the electronic device; and
at least one processor configured to provide power to the first electromagnet and the second electromagnet to supply magnetism having a same polarity as the at least one pen magnet to the first electromagnet to push the at least one pen magnet toward the pen hole and magnetism having a different polarity as the at least one pen magnet to the second electromagnet to pull the at least one pen magnet according to an automatic ejection event of the input pen,wherein the input pen is partially ejected from the electronic device by the first electromagnet reacting to magnetism of the at least one pen magnet of the input pen, and then the partially ejected state of the input pen is maintained by the second electromagnet reacting to magnetism of the at least one pen magnet of the input pen, andwherein the at least one processor is configured to switch, when a re-insertion event occurs while the input pen is kept in the partially ejected state even after a pre-defined time has elapsed, polarities of the first electromagnet and the second electromagnet so that the input pen is automatically drawn into the electronic device.

Abstract
An electronic device is provided. The electronic device includes a input pen including at least one magnet, a housing including a pen guide path for inserting the input pen, at least one electromagnet installed around the pen guide path, wherein the at least one electromagnet is installed to react to the magnetism of the magnet while the input pen is completely inserted into the pen guide path, and at least one processor supplying power having the same polarity as the magnet to the electromagnet according to an automatic ejection event of the input pen to push the magnet out of the electronic device.

12. A method of ejecting an input pen of an electronic device for automatically ejecting, by a first electromagnet and a second electromagnet, the input pen comprising at least one pen magnet, the method comprising:
-
determining whether an input pen automatic ejection event occurs; supplying power to the first electromagnet and the second electromagnet to supply magnetism having a same polarity as the at least one pen magnet to the first electromagnet to push the at least one pen magnet outward of the electronic device and magnetism having a different polarity as the at least one pen magnet to the second electromagnet to pull the at least one pen magnet when the automatic ejection event occurs, wherein the input pen is partially ejected from the electronic device by the first electromagnet reacting to magnetism of the at least one pen magnet of the input pen, and then the partially ejected state of the input pen is maintained by the second electromagnet reacting to magnetism of the at least one pen magnet of the input pen; and switching, when a re-insertion event occurs while the input pen is kept in the partially ejected state even after a pre-defined time has elapsed, polarities of the first electromagnet and the second electromagnet to automatically draw the input pen into the electronic device. - View Dependent Claims (13, 14, 15, 16)
