Portable electronic device and cover mechanism thereof

A cover mechanism for selectively covering at least one opening of a portable electronic device, the portable electronic device comprising a cover, a bezel, and at least one optical device, the bezel having the at least one opening for exposing the at least one optical device, the bezel being connected to the cover and containing the at least one optical device, the cover mechanism comprising:

• at least one rod having a covering portion and a first linkage portion, the at least one rod being pivoted to the bezel for making the covering portion movable between a covering position and an open position relative to the bezel;
• a driving handle movably disposed on the bezel, the first linkage portion being movably connected to the driving handle;
• and
• a rotating member rotatably disposed between the bezel and the cover and having a second linkage portion, the second linkage portion being movably connected to the driving handle;
• wherein when the rotating member rotates, the second linkage portion drives the driving handle to drive the at least one rod to rotate via the first linkage portion, so as to make the covering portion move to the covering position with rotation of the at least one rod to cover the at least one opening, or move to the open position with rotation of the at least one rod to not cover the at least one opening.
