A first rib having an engaging hook is provided in the battery lid, it is used to make engagement of the engaging hook with the first trapezoidal block when the battery lid is engaged with the lower cover, thereby the battery lid is tightly engaged with the lower cover. And a second rib is provided in the battery lid, it is used to move the second trapezoidal block when the pusher rod is moved to separate the battery lid from the lower cover.

Abstract: The present invention relates to a pointing device with multidirectional window viewing function. The pointing device with multidirectional window viewing function comprises a multidirectional roller, which moves in at least three directions and triggers actuating signals corresponding to each direction, including an oblique direction; and a controller, which receives the actuating signal and produces its corresponding source packet, which is received by a receiving terminal. By manipulating the multidirectional roller, a user is able to view and move the text in the window in multiple directions corresponding to the movement of the roller.

Abstract: A seamless mouse comprising a base, with an embedding unit at the rear of the base, a coupling unit in it, a pair of activating troughs near its front, a touch switch in the activating trough, to receive command from the touch operation; and a top cover, at the rear of the top cover and opposite the embedding unit being a joining pin to insert into the embedding unit for fastening purpose, inside it and opposite the coupling unit being a coupling post to couple with the coupling unit, at its front and opposite the activating trough being a driving lever, and extending from the top cover itself being the formation of at least one push key. When the top cover is assembled to the base, the joining pin is fastened to the embedding unit, the coupling post is fastened to the coupling unit. When the push key is pressed, the driving lever activates the touch switch in the activating trough, to serve the function of the mouse.

Abstract: A backlight module is provided for a data input device having at least one element to be illuminated. The backlight module includes a light guide panel, a light source, and a reflective layer. The light guide panel is disposed inside the data input device below the element, and includes a pair of opposed end faces, a bottom face interconnecting the end faces, and a top face opposite to the bottom face and interconnecting the end faces. The bottom face has a plurality of light deflection parts. The top face has a light emanating pattern adapted to correspond to the element. The light source is provided on at least one of the end faces. The reflective layer covers the bottom face.

Abstract: A mouse with replaceable push panel comprising a push panel and a base unit. At an appropriate position of the base unit, such as its front or its rear, there is at least one embedding unit, the embedding unit having a trough, at the bottom of the trough being a check unit, on the push panel and opposite the embedding unit being a fastening key, at the end of the fastening key being a cone-shaped fastening unit. When the push panel is joined to the base unit, the fastening key penetrates the trough of the embedding unit, and its cone-shaped fastening unit is then fastened to the check unit, or they may also be pulled apart by separate the push panel from the base unit, for the purpose of convenient replacement of the push panel. Besides, inside the push panel can be installed a battery compartment to accommodate a battery for its application to a wireless mouse.

Abstract: A push key with replaceable key cap, comprising a key cap unit, an external ring on top of the key cap unit, the formation of a hollow accommodating chamber inside the external ring, and a key cap. Below the key cap and in keeping with the shape of the external ring is a coupling unit that can be coupled with the external ring. Inside the key cap and extending downward is a key post reaching into the accommodating chamber. Basically, the key cap and the external ring are coupled with each other to enable convenient replacement of the key cap.

Abstract: A key switch having a replaceable key cap is provided. The key switch includes a main key body (10) having a pair of cross-ribs (14). The pair of cross-ribs (14) define a plurality of recesses within the main key body (10). A replaceable key cap (20) has an upper wall and a substantially annular sidewall which define a hollow chamber therein. A plurality of locking members (22) project from a lower surface of the upper wall within the hollow chamber. Each of the locking members (22) has a locking flange projecting therefrom and each of the plurality of locking members (22) is releasably received by a respective one of the plurality of recesses, with the locking flanges releasably engaging respective cross-ribs (14).

Abstract: The invention relates to an optical mouse, comprising a base unit, a transmitter and a receptor installed in the base unit to obtain coordinates, a transparent or semi-transparent sensing board that is installed above the transmitter and the receptor, and an accommodating chamber to accommodate the sensing board. The sensing board is capable of movement, front and back, left and right, inside the accommodating chamber, so designed that the signals transmitted from the transmitter are reflected by the sensing board back to the receptor to measure its coordinates. Then, whenever there is any movement of the sensing board, the change of movement is calculated to indicate the movement of cursor, so that the optical mouse can be used to move the cursor.

Abstract: A device for releasably mounting a wrist support to a keyboard is disclosed. The device includes a slide movably received in a slot defined in a front extension of the keyboard. The slide has a bottom projection extending beyond a bottom face of the keyboard for manually moving the slide and an L-shaped top projection having a segment spaced from a top surface of the slide for defining a channel. A guide plate is fixed to the keyboard by a bolt and has an edge movably received in the channel for retaining the slide in the slot and guiding the movement of the slide. A catch is attached to the slide to be movable therewith between a released position and a secured position. The catch forms a barb whereby when the catch is at the secured position, the barb engages an opening defined in the wrist support for securing the wrist support to the keyboard and when the catch is at the released position, the barb disengages from the opening of the wrist support for releasing the wrist support from the keyboard.
