An operation button (7) is secured to the latching lock, whereby when the operation button is moved the latching lock and the elastic body move correspondingly. When the battery lid is locked to the casing, the wedging hooks (32) engage in recessing holes (52) of the casing, and the wedging hooks (34) engage with the wedging hooks (94).

Abstract: The invention is related a keystroke structure (3) for an electronic device which includes a shell (2) defining an opening (22). The keystroke structure comprises a cap (32) made of hard plastics such as ABS resin, a flange (34) fixed to a bottom of a periphery of the cap, wherein the flange is made of a material, such as rubber which is more elastic than that for forming the cap. The cap has a portion extending upward through the opening. A rod (42) extends downwardly from a bottom of the cap. A switch assembly (4) consisting of four first switches (44) for cursor direction control and a second switch (46) for “enter” control. The first switches are activated by the rod when the cap is titled, and the second switch is activated by the rod when the cap is vertically depressed. When the cap is titled to activate one of the first switches, the flange engage with a bottom face of the shell.

Abstract: The invention is to provide a resetting device, of separable extensive accessory, connected between an portable device and an IC arranged in a separable extensive accessory, and it is characterized: by using a simple logic circuit, it is possible to complete the resetting action of the IC arranged on the extensive accessory when the connecting relationship between the separable extensive accessory and the portable device is changed.

Abstract: A protective cover with ternary structure applied in an electronic product comprises a conjoint plate, a flexible plate connected to the conjoint plate, and a fastening plate connected to the flexible plate. The fastening plate snaps the bottom cover for covering the expansion slot of the electronic product. Also, the conjoint plate, the flexible plate, and the fastening plate are integrated as a whole by double injection technique, and the flexibility of the flexible plate controls the protective cover being closed or opened.

Abstract: A power switch apparatus is disclosed wherein the switch apparatus is applicable in an electronic product comprising a switch device capable of being switched between ON and OFF conditions. The power switch apparatus comprises an active element and a flexible arm. The active element installed inside the electronic product comprises a first connector and is coupled to the switch device. The ON and OFF conditions of the switch device correspond to the different positions of the active element. The flexible arm comprises a second connector and a contactor. The second connector is used to clip with the first connector at the ON condition. The electronic product is configured such that the contactor is not covered and remains accessible. The movement of the contactor is able to transform the shape of the flexible arm and to release the clipping relation between the first connector and the second connector.

Abstract: A stylus-accommodating structure for a wireless communication apparatus includes a printed-circuit board (3), a receiving block (31) and a planar antenna (33). The receiving block further includes an outer surface (300) and a tunnel (310) for receiving a stylus (5). By providing the planar antenna (33) to be formed on the outer surface of the receiving block and further the receiving block to be built at the printed-circuit board, the wireless communication apparatus equipped with the stylus-accommodating structure can then be presented more compact.

Abstract: A wireless communication apparatus integrates a flat speaker (33) onto a liquid crystal display (12) or a rotational shield (3) of the apparatus. The flat speaker includes a vibrator (30) and a transparent vibrating membrane (31) which generates sound when the vibrator vibrates. The transparent vibrating membrane is mounted with a predetermined spacing over the liquid crystal display or over an inner surface of the rotational shield so as to gain a broader voicing surface. Thereby, by providing the flat speaker, the wireless communication apparatus can have a better audio effect.
