  • Publication number: 20100133398
    Abstract: A linkage and a supporter are attached to a back of the housing via a magnetic element of an electronic device with a magnetic supporter. The supporter is drawn to a supporting position via the linkage to support the electronic device body and provide various angles for the user to easily operate the electronic device in several modes. Moreover, since the linkage and the supporter are attached via the magnetic element, when the electronic device body is overloaded, for example, a user applies overlarge force to operate a touch panel, the magnetic element is detached from the electronic device body to prevent the linkage and the supporter from being damaged or permanently destroyed.
