Abstract: A mobile video/audio device is provided, comprising a receiving box, a display mounted on a surface of the receiving box for displaying a video content with a corresponding audio content accompanied, a compact disk (CD) drive disposed within the receiving box with an access side thereof exposed and having an eject button formed at a side thereof, a control module comprising a video/audio playing circuit formed in modules for controlling the display, CD drive and other units associated with the video/audio playing circuit, the control module being further disposed within the receiving box and detachable therefrom; and a control panel disposed at a location outside the display within the receiving box and having a plurality of control keys for controlling the control module to play the video/audio content and a plurality of video/audio out/input ports for connecting with an external device.

Abstract: A computer mouse includes a sliding cover and a control platform. The sliding cover is disposed on the top surface of the computer mouse, and the control platform is disposed under the sliding cover. Several control keys are provided on the control platform. Two rails are provided on the sliding cover and two grooves are provided on the computer mouse so that the sliding cover may be slid downwards. When the sliding cover is slid downwards, the control keys may be automatically activated. When the sliding cover is closed, the computer mouse looks like a regular computer mouse; when the sliding cover is opened, the control keys may be automatically activated and a user may access the control keys.

Abstract: An optical input-sensing device for moving a pointer by optics is disclosed. The optical input-sensing device is composed of an optical sensing chip, a luminous body, a lens and a transparent plate. The luminous body projects light to a light-sensing range of the transparent plate having functions of fixing the imaging distance and assisting focus. Then the optical sensing chip gets the image of the movement of an objective, such as a finger or pen, and converts the movement image into data information so as to get the moving direction for moving the pointer.

Abstract: This invention relates to a scroll bar input device for a mouse, the scroll bar input device being installed inside mouse body for executing a scroll up or scroll down action for the computer screen. The scroll bar input device has a base, a locating seat, a first shaft bracket, a roller, a rotating wheel, an encoder, a second shaft bracket and a microswitch. The first shaft bracket has a wheel hub with contacts, the wheel hub inserted into the rotating wheel. The encoder is in contact with first teeth of the rotating wheel to transmit or receive signals for moving up and down the computer screen.

Abstract: Disclosed is an improved structure for a paper shredder in a waste paper disposer formed of one piece design composed of a hanging portion, and a shredder body with a plurality of scrapping elements and guiding slots. The structure is divided in two parts, provided respectively at the front and rear sides of a cutter assembly. During operation of the paper shredder, the paper shreds are removed from the cutter assembly by the scrapping elements of the shredder body thereby preventing the paper scraps from sticking on the cutter surfaces. Paper scraps sticking on the cutter blades are removed by barrier tips on the upper ends of the guide slots. When the paper shredder is reversely revolved, the remaining paper shreds on the cutter are removed by the barrier tails formed at the bottom portion of the shredder and the guide slots.

Abstract: A computer mouse includes an upper cover and a chassis. The upper cover and the key assembly are made with one-piece construction. The upper cover and the chassis are separately provided with a buckle and fastener mechanism for connecting those two elements together. By this arrangement, the upper cover can be readily attached to the chassis without applying screws or similar fasteners. A Y-shape slot is provided at the encoding wheel supporter for easy mounting of the encoding wheel and adding lubricant. The skidding pads are provided with ratchet hookers to readily attach to the mounting holes of the chassis. The roller is mounted on a U-shaped elastic sheet for providing a biasing force to the tracing ball. The roller mechanism can be readily mounted on the roller bracket of the chassis.

Abstract: An optical-reflecting decoder modular design mechanism of mouse which is all components of mouse control circuit to adhere to the PCB using SMT technic, and this PCB is installed on a base which has two small size slotted discs, one ball member and one idle roller. Besides, the end of mouse cable has a connector which has several slots on the top center, and each slot has a connecting spring, and at the end of each spring has a connecting protuberance in order to touch to the touching point of the PCB. Also two sets of LED and phototransistors are adhered to the back of PCB, and installed reflecting lens under each LED and phototransistor, and install on the rack of two lens in a proper slope angle for light reflection.
