Abstract: A portable electronic device is provided, including a main body, a C-shaped member, and a hinge module, wherein the main body includes a display surface and the C-shaped member includes an opening. The hinge module pivotally connects the main body with the C-shaped member. When the main body is situated in a first position, the main body covers the opening. When the main body rotates from the first position around an axis to a second position relative to the C-shaped member via the hinge module, the main body is away from the opening. An acute angle is formed between the axis and the display surface.

Abstract: A connector module comprises a casing, a rotating element, a fixing element and a connector. The rotating element is rotatably disposed within the casing. The fixing element is fixedly disposed within the casing. During the fixing element being fixed to the rotating element, the fixing element and the rotating element usually and electrically contact. The connector is disposed on the rotating element and electrically connects with the fixing element through the rotating element.

Abstract: A rotary mechanism is provided, including a first housing, a second housing, a rotary module, an elastic element, and a speed-reduction module. The rotary module connects to the first housing and extends therefrom to connect with the second housing. The elastic element connects the second housing and the rotary module. The speed-reduction module connects to the rotary module. When an external force is exerted on the second housing, and the second housing rotates relative to the first housing along a first direction, the elastic element stores an elastic potential energy. When the external force is released, the second housing rotates relative to the first housing along a second direction by the elastic force. The second direction is opposite to the first direction, and the speed-reduction module reduces the rotary speed of the second housing relative to the first housing.
