Abstract: An electronic device casing adapted to cover an antenna is provided. The electronic device casing includes a supporting layer and a carbon fiber layer. The carbon fiber layer is disposed on a surface of the supporting layer and includes a signal passing region having a plurality of slits and a plurality of microstructures separated by the slits. The signal passing region is adapted to cover the antenna, and a signal excited by the antenna is adapted to pass through the supporting layer and the slits so as to pass through the electronic device casing. An electronic device having the electronic device casing is further provided.

Abstract: Stylus includes a first body at the front end and a second body at the back end, where the second body pivots to the first body and is capable of rotating between a straight position and a bending position. The stylus further includes a restraining member selectively moving to engage between the first body and the second body such that the stylus can be retained and formed in a straight pen style with buckling-proof capability, or a bending style for supporting a portable device. When the stylus is drawn out of the portable device, the restraining member can further be pushed forwardly to disengage the second body from the first body by a resilient bump inside the housing of the portable device, so that the stylus can be released from the straight pen style and bended accordingly.

Abstract: A moving mechanism is provided, including a torsion hinge, a slider, a lock member, and an elastic member disposed on the slider. The torsion hinge has a first plate and a second plate rotatable relative to each other. The lock member is rotatable relative to the first plate, and the slider is movably disposed on the second plate. When the moving mechanism is in a closed state, the lock member is engaged with a slot portion of the second plate, so as to restrict the second plate in a predetermined angle. When the slider slides relative to the second plate to a critical position, the elastic member pushes the lock member to release from the slot portion, such that the second plate is rotatable to an open position.

Abstract: A moving mechanism of an electronic device is provided, including a first member, a second member, a sliding member slidably connected to the first member, and a pivot rotatably connecting the second member with the sliding member. When the first member slides relative to the sliding member, a latch member on the first member is pressed by the sliding member to a retracted position. When the sliding member is released from an initial angle and rotates relative to the second member, the latch member is pushed by a resilient element and is joined in a recess of the sliding member, thus preventing sliding between the first member and the sliding member.

Abstract: A semi-auto sliding mechanism is provided, including a first member, a second member, a first rack, a second rack, a pinion gear pivotally connected to the second member, and a clockwork spring connecting the pinion gear to the second member. The first and second racks are disposed on the first member. When the first member is moved relative to the second member to a first position by an external force, the pinion gear rolls along the first rack, and an elastic potential energy is stored in the clockwork spring. When the external force is released, the clockwork spring impels the pinion gear to rotate along the second rack, such that the first member moves relative to the second member from the first position to a second position.

Abstract: A handheld electronic device including a first body, a second body and a linkage is provided. The second body is stacked on the first body, and a first fulcrum at an end of the second body is slidably disposed on the first body. The linkage provided with an end pivotally connected to the first body via a pivot and another end slidably disposed on the second body via a second fulcrum is located between the first body and the second body. When the electronic device is transformed from a retracted state to an expanded state, the second body slides relative to the first body and then the second fulcrum is raised to form an included angle between the first body and the second body.
