Abstract: A hot-key mouse is to position several hot keys on both sides of a scroll wheel of the mouse, excepting remaining original design of the left and the right mouse buttons, the hot keys are positioned adjacent to the scroll wheel and between the left and the right mouse buttons without hindering the operations of the left and the right mouse buttons. Those hot keys are pre-defined by functions for either the left or the right hand user to operate without changing another type of mouse. The invention enables the hot-key mouse to be commonly used by either the left or the right hand user, in addition, to reduce the manufacturing cost.

Abstract: A computer keyboard has a receiving space. A lateral side of the receiving space is installed with an inserting seat for being inserted by a charging seat. A lateral side of the charging seat is exactly inserted by a plug at an interior of the receptacle of the keyboard. A top of the charging seat has a transmission slot for installing a mobile phone. The specification of the transmission slot is designed based on the specification of the mobile phone to be inserted. The charging seat is made as a plug-in structure. The plug of the charging seat is made according to the specification of the charging seat of a mobile phone. Thereby, the mobile phone can be charged by the receptacle of the keyboard and thereby, a multi-functional keyboard is formed.

Abstract: An improved key structure for computer keyboards includes two crossed support frames that, after pivotal connection, have center limiting rods projecting respectively from outer sides of the connecting position. Left and right slide rods respectively project from both sides of a horizontal rod at a bottom end of the two crossed support frames, with an inverted U-shaped groove disposed at a middle section and straddling on the limiting plates of the corresponding key base so that when the crossed support frames are compressed and lie down in a closed state, they will not deviate. Two opposite slide bars that orient inwardly are provided on upper ends of the crossed support frames. Four slide holes are respectively provided on a bottom face of a key unit corresponding to the slide bars so that the slide bars can be positioned in the four slide holes and cause the two crossed frames to lie flat.

Abstract: A keyboard includes a body having a number of depressions formed in the upper portion for collecting water, a-number of channels extend upward from the depression for slidably receiving buttons. A base is secured to bottom of the body and a casing is secured to bottom of the base. A number of conduits extend downward from the depression for communicating the depressions with the casing for allowing water collected in the depressions to flow into the casing so as to prevent water from flowing into the circuit board received between the body and the base.
