1. A control device for controlling a cursor motion of an electronic device, said control device comprising: a holder having an accommodation space therein; a flexible sleeve sheathed around said holder, and rotatable and movable on said holder, wherein a touch-feel enhancing mechanism is formed on an outer surface of said flexible sleeve; a detecting module for detecting at least one of a rotating action and a moving action of said flexible sleeve, thereby generating a control signal to control said cursor motion of said electronic device; and wherein said control device further comprises a housing for accommodating said holder, a positioning shaft, a pushing seat including a magnetic element, a pressing element and a sensing unit, wherein said positioning shaft, said pushing seat, said pressing element and said sensing unit are all accommodated within said housing, wherein said holder is fixed on said pressing element, said pressing element is rotatably fixed on an end of said positioning shaft, and said end of said positioning shaft is penetrated through said pushing seat and sustained against said pressing element, wherein when an external force is exerted on said pushing seat through said flexible sleeve, a distance between said pushing seat and said pressing element is changed, so that a change of a magnetic field of said magnetic element is received by said sensing unit. |
