Abstract: An electronic device includes a casing, a circuit board, a plurality of connecting elements and a keyboard module. The circuit board is disposed at the casing, and the connecting elements connect the circuit board and the casing. Each of the connecting elements includes a stopper, and the circuit board is disposed between the stopper and the casing. The keyboard module is disposed on the casing, and the stopper supports the keyboard module.

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 noise reduction key structure is disclosed. The noise reduction key structure is applied to an electronic device having a housing and a substrate, the substrate being installed in the housing, the housing having a key portion, the noise reduction key structure comprising: a switch element which is installed on the substrate in response to the key portion; and an encapsulation which has a hole, wherein the hole encapsulates on the up side of the substrate, so that the substrate and the encapsulation together encapsulate the switch element into a chamber of the encapsulation, whereby when the key portion is pressed down, the key portion triggers the encapsulation to further trigger the switch element, and the encapsulation can reduce the noise of triggering the switch element.
