Abstract
A planetary type dual-shaft hinge includes a female shaft, a male shaft set including first and second male shafts respectively inserted through the female shaft, and a transmission mechanism including first and second transmission members respectively connected to the first and second male shafts and a link pivotally coupled between the first and second transmission members in such a manner that the pivoting points between the link and the first and second transmission members are disposed at two opposite sides relative to the central axes of the first and second transmission members so that when the user opens the cover member of the flip-up electronic device in which the hinge is used, the first male shaft is turned around the second male shaft to smoothen the movement of the cover member.
