Abstract: An adjustable supporting mechanism suitable for being connected to a body of an electronic apparatus, upholding the body on a plane, and adjusting the relative position of the body and the plane is provided. The adjustable supporting mechanism includes a base, a bearing, an elastomer, a rotating shaft, and a supporting stand. The base is capable of being connected to the body. The bearing is fixed on the base. The elastomer is fixed on the base. The rotating shaft fits the bearing and contacts the elastomer. The rotating shaft is capable of rotating with respect to the base and the elastomer. When the rotating shaft rotates, the elastomer applies a resistance on the rotating shaft for resisting the rotation of the rotating shaft. The supporting stand is fixed to the rotating shaft.

Abstract: A rotatable support mechanism is attached to a body of an electronic device for upholding the body on a plane and adjusting relative positions between the body and the plane. The rotatable support mechanism includes a base, a rotatable disk, and an elastic stopper. The base attached to the body of the electronic device has an axle. The rotatable disk has a holder and a groove. The axle passes a sidewall of the groove. The rotatable disk rotates around the axle as an axis. The sidewall of the groove has at least an opening. The elastic stopper mounted to the axle has an elastic shell fragment and does not rotate with the disk. As the disk is rotated, the elastic shell fragment enters and passes through the opening to exert a resistance force to the disk. Therefore, the electronic device is upheld vertically or horizontally by the rotatable support mechanism.

Abstract: The present invention relates to a locking/releasing apparatus, which comprises: a positioning mechanism disposed at a bottom plate of a fastener, a locking element, a positioning spring, a releasing spring, and a protruding pillar disposed at the bottom of a movable member, such that if the movable member is pushed into the fastener, the protruding pillar will be pushed to press against a guiding rim to rotate the locking element and drive the positioning spring to store energy, and if the protruding pillar continues to be pushed and blocked by the locking element, the protruding pillar will enter into a slot channel from a guiding gap. Then, the positioning spring releases energy to rotate the locking element in an opposite direction, and thus the protruding pillar is moved to a guiding concave to be accommodated and fixed.

Abstract: A storing mechanism suitable for being disposed in an electronic device is provided, which is used to store a first hard disk with a first thickness or a second hard disk with a second thickness. The storing mechanism includes a first module, a second module and a restoring element. The first module includes a base and a lever. The lever having a leaned portion is pivoted to the base. Additionally, the second module includes a tray and a slide. The tray is glidingly disposed on the base, and has a stopper for being limited to the leaned portion, so as to limit the shift of the tray relative to the base. The slide is glidingly disposed on the tray. Moreover, the restoring element is disposed between the base and the tray for making the delocalized tray move back to the original location.

Abstract: A positioning apparatus for a data storage device is provided to firmly install the data storage device in a frame, to conveniently assemble/disassemble the data storage device on/from the frame, to reduce manufacturing costs and to reduce assembly steps. The positioning apparatus for the data storage device comprises a first locking part and a locking module. The first locking part connects with the data storage device. The locking module comprises a body, a second locking part, and an elastomer. When the data storage device is installed at the preset location of the frame along the first direction, the elastomer of the locking module installed along the second direction and outside of the frame forces the second locking part to restrain the moving of the first locking part along the first direction. The data storage device can be disassembled from the frame by removing the restraint described above.
