  • Patent number: 8964362
    Abstract: A handheld electronic device, including a first body, a second body, a sliding module and at least one rotating module. The sliding module is coupled to the second body, so that the second body is suitable for sliding 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 suitable for rotating relative to the first body. The second body receives a force to rotate from the second position to a critical position. When the second body passes the critical position, the rotating module releases a potential stored when the second body receives the force to drive the second body to rotate to a third position and form an included angle between the first body and the second body. A sliding mechanism assembly is also disclosed.

  • Publication number: 20110173645
    Abstract: A disc loading and ejecting apparatus for a slot-in optical disc drive to drive a compact disc into and out of the slot-in optical disc drive includes a driving portion and a guiding portion that are located at two opposite sides of the slot-in optical disc drive. The driving portion includes a transverse roller. The compact disc has one end abutted and held by the guiding portion and another end leaned on the roller. The roller can be rotated to load and eject the compact disc into or out of the slot-in optical disc drive. The roller is located at one end of the loading/ejecting path of the compact disc without extending traversely or occupying the transverse space of the path, thus the slot-in optical disc drive can be shrunk to a smaller size to meet slim and light design requirements.
