Abstract: The present invention is to provide a computer mouse having a windable output wire including a housing, a windable wire receiving device retractably mounted in the housing, and an output wire having a first end connected to the wire receiving device and a second end connected to an output plug that is inserted into a main frame of a computer. The output wire is wound around the fixing shaft center, thereby forming an inner circle structure of the output wire, and is wound around a mobile shaft center, thereby forming an outer circle structure of the output wire. The inner circle structure of the output wire and the outer circle structure of the output wire are along two opposite directions, thereby previously leaving a wire winding space, reducing the volume of the housing, and saving the cost of fabrication.

Abstract: A selector pen for touch screen includes a barrel having a light emitter mounted therein to be turned on or off through turning of a switch rotatably connected to a rear end of the barrel. The switch includes a base defining a non-circular insertion hole, a movable rod being fixedly received in the insertion hole of the movable rod and having an inclined top formed into a spiral guide surface, and a cap being rotatably covered onto the base and having an internal projection. When the cap is turned, the projection slides along the spiral guide surface to gradually depress the movable rod for the same to electrically make the light emitter. The switch has simplified structure and the spiral guide surface defines a definite range of turning for the cap.
