Abstract: A moving module and an electronic device are provided. The electronic device includes a first body, a second body, and the moving module disposed between the first and second bodies. The moving module includes a rail, a moving element, and an elastic element. The moving element is in contact with the rail. The elastic element is connected between the moving element and the first body. When the moving element moves from a first end of the rail to a curved portion of the rail, a force exerted on the elastic element by the moving element is gradually increased. When the moving element passes the curved portion, an elastic restoration force of the elastic element drives the moving element to move toward a second end of the rail. When the moving element reaches the first end or the second end, the first body and the second body interfere with each other.

Abstract: A locking mechanism and an electronic device are provided. The electronic device includes a first body, a second body, a moving module, and a locking mechanism. The moving module is disposed between the first body and the second body, so that the second body is rotatable and tiltable relative to the first body. The locking mechanism includes a first connecting member and a plug. When the plug is coupled with the first connecting member by a magnetic force, the second body is slidable relative to the first body. When the second body is tilted up to decouple the plug from the first connecting member, the plug interferes the moving module, so that the second body is not slidable relative to the first body.

Abstract: A handheld electronic device and an operating method thereof are provided. The handheld electronic device includes a first body, a second body, and a moving assembly. The moving assembly includes a sliding module and at least one rotating module. The sliding module is coupled to the second body, wherein the second body is moveable between a first position and a second position. The rotating module is coupled between the first body and the sliding module so that the second body is rotated relative to the first body. The second body is automatically rotated from the second position to a third position to form a first angle with the first body. The second body can be rotated between the third position and a fourth position to form a second angle with the first body, wherein the second angle is greater than the first angle.

Abstract: A Personal Digital Assistant (PDA) with retractable stylus comprises a retractable stylus, a housing, a stylus slot, and a push portion, wherein a contact pad is attached to the inner side of the push portion. The retractable stylus comprises a pen shaft having a release button, a pen body having an opening, and a spring situated inside the pen body. When an external force is applied to the pen shaft downward, the spring is compressed until the opening holding the release button; thus, the stylus is shortened. When the release button is set free from the opening, the spring elasticity ejects the pen shaft upward; thus, the stylus returns to the full-length condition. If the stylus is kept in the stylus slot, an external force applied to the push portion can make the contact pad press the release button; so the pen shaft is ejected upward by spring elasticity.
