## Abstract

A portable electronic device including a first body, a driving source, a stand, a second body and a magnetic driven component is provided. The driving source is disposed in the first body and includes a motor and a screw rod coupled to the motor. The screw rod has a magnetic screw thread portion. The stand is pivoted to the first body, and the second body is pivoted to the stand. The magnetic driven component is disposed at a side of the second body and the magnetic driven component is magnetically attracted to the magnetic screw thread portion of the screw rod. The motor drives the screw rod to rotate and the magnetic screw thread portion drives the magnetic driven component slide on the first body. The second body and the magnetic driven component move synchronously and drive the stand rotate with respect to the first body.
