Abstract: A button structure applied to an electronic device includes a housing, a button plate, a support element and a printed circuit board. The button plate is contained to a central opening of the housing. The central region of the button plate has a first thickness, while two sides of the button plate have a second thickness. The second thickness is thicker than the first thickness. The ends of the button plate are separately formed as elastic arms for mounting the button plate to the housing. The support element is sited under the button plate right under the central region so as to define the support element into left and right parts. The printed circuit board located under the support element and has two switches separately corresponding to the left and right parts of the button plate.

Abstract: A memory disk structure includes a storage device, a hollow casing, an elastic member and a base. The storage device has a connector and a main body. The connector is installed in one end of the main body. The hollow casing has an opening and a recess with a protrusion. The elastic member and the base are attached to the main body, and the base has an engagement portion. When the connector passes through the opening of the hollow casing to make connector pushed into the hollow casing, the elastic member is deformed to make the engagement portion wedge in the recess and against the protrusion, and when the body is pushed into the hollow casing and the connector is exposed outside the hollow casing, the elastic member is fastened at the first recess to prevent the storage device from departing from the hollow casing.

Abstract: A portable storage device is provided. A housing has a first opening and a second opening. A storage body has a connector and a pair of positional restriction structures. The storage body slides in the housing to make the connector extend outside the housing or hide in the housing via the first opening. A pair of actuating arms is provided in the housing and can swing. An actuating structure is partially exposed outside the housing via the second opening and pivotally connected to the pair of actuating arms. An elastic element is connected to the actuating structure and the storage body, so that the elastic element pushes the storage body and drives the actuating arms to return to the original position to block the positional restriction structures.

Abstract: A portable storage device structure is described. A memory device has a connector and a first concave portion. An opening defined on a hollow housing to form two sections of the hollow housing with different lengths. The longer section has a second concave portion. A resilient member has one end secured to the second concave portion to suspend the opposite end. When the memory device assembles to the hollow housing, the opposite end of the resilient member engages with the first concave portion to avoid the memory device from slipping out of the housing.

Abstract: A kinetic energy transferring element applied to a button structure for pressing an electric switch has a curved portion, a first extended portion and a second extended portion, in which the curved portion is bridged between the first extended portion and the second extended portion. The first extended portion is served as a fulcrum of the transferring element, while the second extended portion is a free end to receive foreign application. When the user presses the second extended portion, the curved portion of the kinetic energy transferring element can protrude to touch the electric switch.

Abstract: A button structure applied to an electronic device includes a housing, a button plate, a support element and a printed circuit board. The button plate is contained to a central opening of the housing. The central region of the button plate has a first thickness, while two sides of the button plate have a second thickness. The second thickness is thicker than the first thickness. The ends of the button plate are separately formed as elastic arms for mounting the button plate to the housing. The support element is sited under the button plate right under the central region so as to define the support element into left and right parts. The printed circuit board located under the support element and has two switches separately corresponding to the left and right parts of the button plate.

Abstract: A fastening mechanism includes a first engagement element, a movable plate and a press button. The first engagement element is attached to a display device. The movable plate is disposed movably within a casing and has a second engagement element for engaging with and disengaging from the first engagement element when the display device covers the casing. The press button is mounted on the movable plate for synchronous movement therewith. Inward and outward movements of the movable plate together with the press button with respect to the casing result in engagement of the first and second engagement elements and disengagement of the first and second engagement elements.
