Claim Text:
1. An electronic device, comprising: a first body; a second body, connected to the first body and capable of being opened and closed relative to the first body, and having a sliding slot; a linking-up member, fixed to the first body, and having a shaft portion pivoted to the sliding slot, wherein the first body rotates about a rotation shaft of the shaft portion relative to the second body along with and the linking-up member and moves along the sliding slot; and a restriction member, assembled to the second body, wherein the linking-up member is movably coupled to the restriction member according to a contour thereof, wherein the first body is applied with an external force to rotate about the rotation shaft along with the linking-up member, so as to drive the linking-up member to move relative to the restriction member, and drive the shaft portion to slide back and forth along the sliding slot, such that the first body is transformed between a first state and a second state relative to the second body, wherein the linking-up member is a cam, and at least a part of a curved contour of the cam movably leans against the restriction member to form a stroke for moving relative to the restriction member, wherein the stroke comprises a first segment and a second segment adjacent to each other and an inflection point between the first segment and the second segment, and wherein the first segment and the second segment respectively have a buffer region located away from the inflection point, and a relative moving speed of the restriction member at each of the buffer regions is smaller than a relative moving speed of the restriction member at regions other than the buffer regions.
