Abstract: The present disclosure discloses a key unit. The key unit comprises a movable body, an elastic body, and a switch layer comprising a plurality of control switches that are arrayed, wherein along a vertical direction, one end of the elastic body is abutted against a non-central region of the movable body, the other end of the elastic body is selectively pressed against the switch layer under pressing drive of the movable body to adjust an operating state of the control switches of the switch layer. In addition, the present disclosure further provides a keyboard which employs arrays of the key units. With the keyboard unit according to the present disclosure, the quantity of elements is reduced, the structure is simplified, the assembling is facilitated, and the dust-proofing performance is improved.

Abstract: A personal data assistant (PDA) carrying case includes a main body (10), an expansion cover (40) having a first clasp (46) extending therefrom, a resilient clip (22) mounted on the main body, and a button (29). An opening (33) is defined in the main body for matching the expansion cover. A locking edge (36) is formed for engaging with the first clasp. A through hole (24) is defined in main body corresponding to the first clasp. The resilient clip has a projecting portion (222) corresponding to the through hole. The resilient clip deforms elastically to have the projecting portion pressing the button, so that the button drives the first clasp to disengage the first clasp from the locking edge of the main body.

Abstract: A PDA carrying device includes a base body (20), a front panel (10) and rear cover (30). The base body is used to hold a PDA. The front panel is pivotably attached to the base body. The rear cover is mounted on the base body. The base body has a plurality of hermetic flanges engaging with the front panel and the rear cover respectively.

Abstract: A mounting apparatus is used to secure a data storage device (10). The data storage device has a mounting member (12) disposed thereon. The mounting apparatus includes a bracket (30) for accommodating the data storage device, and a latch member (50) removably attached to the bracket. The bracket includes a side plate (32), which defines a through opening therein, for receiving the mounting member of the data storage device along a first direction. A guideway (327) is disposed on the side plate. The guideway extends in a second direction perpendicular to the first direction. After the mounting member of the data storage device is received into through opening of the bracket, the latch member is inserted into the guideway, thereby preventing the mounting member from disengaging from the through opening.

Abstract: A computer enclosure includes a chassis (20), and a bracket (10) pivotably attached to the chassis. The chassis includes a front plate (27). A first pivot portion (271) is formed along an edge of the front plate. A cutout (272) is defined adjacent the pivot portion along the edge thereof. The bracket forms a second pivot portion (121) thereon. The second pivot portion inserts through the cutout to slide on along the edge of the front plate, thereby the second pivot portion engaging with the first pivot portion.

Abstract: A computer enclosure includes a chassis (30), a top cover (10) for covering the chassis, and a locking member (50). A side wall (33) is bent from the chassis. A stop portion (342) is horizontally formed on the side wall. The locking member is slidably attached to the top cover. A locking portion (58) is vertically extending from the locking member corresponding to the stop portion of the chassis. A slope (582) is formed on the locking portion, for abutting against the stop portion of the chassis. A resilient member (70) is connected to the locking member and the top cover, for allowing the locking member to be offset, thereby the locking member riding over the stop portion and engaging therewith.
