Abstract:
A cursor controlling device, in which the cursor controlling device is used to control a displacement and location of a cursor on a computer display, said cursor controlling device comprising:a case which is comprised of an upper piece and a lower piece, a cavity being formed between the upper piece and the lower piece;an information carrier set within said case and having at least two information carriers for recording information signals used to identify ""0"" and ""1"", so as to record two dimensional movement of said cursor controlling device along an X axis and a Y axis;a reading set installed within the case for coupling with said information carrier to drive the ""0"" and ""1"" signals corresponding to said two dimensional movement of said cursor controlling device;a sliding bar set having at least an X axis sensor and a Y axis sensor set for driving said information carrier, respectively, bars of said sliding bar set being slidable relative to said case,wherein said installed information carrier is serially and actively connected to a portion of said case, and each of said information carriers has a driving portion which is projected to the external side of said case in order to be driven by the respective sliding bar set, whereby an assembled volume of said cursor controlling device is reduced to a minimum value so that the cursor controlling device may be moved within a very small area to control movement of the cursor on the display.
