A notebook computer device includes an image capture module, a cover, a first magnetic element, and a second magnetic element. The image capture module is disposed on a body of the computer device, the cover is moveably disposed on the body. The image capture module is exposed when the cover is at a first position, and the image capture module is covered when the cover is at a second position. The first magnet element is disposed on the cover, and a second magnet element is disposed on the body corresponding to the first magnet element. The cover moves between a first position and a second position via the magnetic force of repulsion and attraction.
