Abstract:
1. A control device for controlling movement of a cursor of an electronic device, said control device comprising: a holder defining an accommodation chamber therein; a sleeve sleeved onto said holder, wherein said sleeve is rotatable and movable on said holder; a detecting module accommodated within said accommodation chamber for detecting a rotation and a translational movement of said sleeve; a sensor optionally triggered to generate a control signal; and a positioning mechanism comprising a positioning part and a transmission member, wherein said transmission member includes two extension coupling parts connecting said positioning part to opposite ends of said holder, respectively, and a pressing part assembled to said positioning part between said two extension coupling parts and aligned with said sensor, wherein when said holder generates a first vertical displacement, said pressing part of said transmission member is transmitted through said positioning part to generate a second vertical displacement in response to said first vertical displacement of said holder, and said first vertical displacement is different from said second vertical displacement.
