Abstract: PURPOSE: To enable all the input means to control a single cursor by connecting the plural input means to a computer system with a single input port. CONSTITUTION: A selective controller 50 connected with at least two cursor controllers 10 is included so that each cursor controller may transmit a control signal to the selective controller and the selective controller may send a cursor moving signal corresponding to the control signal from the cursor controllers to the computer system. When a presently selected cursor controller is in an active state through a delay period longer than a periodical period between the transmission of the control signal, the selective controller 50 release the selection of the cursor controller to transmit the cursor movement signal to the computer system from another cursor controller coming into an active state to be selected.
