An electronic device includes a first body, a first supporting member, and a second body. The first supporting member has a first end and a second end opposite to each other, and the first end is pivoted at the first body. The second body has a notch, the second end is pivoted at the second body, and the first supporting member is fitted to the notch. The second body and the first supporting member fitted to the notch are closed or opened up with respect to the first body together as the first supporting member is pivotally rotated relative to the first body. When the second body is opened up, the second body and the first supporting member are pivotally rotated relatively to separate the first supporting member from the notch and move a bottom end of the second body to a preset position on the first body.
