A paper grabbing assembly is provided. The paper grabbing assembly includes: a base with a pivot seat disposed thereon, wherein the shaft is pivotally disposed on the pivot seat; a bearing plate, pivotally disposed on the base corresponding to the paper grabbing roller; a driven member, connected to one end of the shaft; a cam member and an elastic member, rotatablely fitted on the shaft. The elastic member frictionally contacts the cam member and the driven member respectively, such that the driven member rotates the cam member via the elastic member, for pressing the bearing plate away from the paper grabbing roller. Further, when the cam member is stopped, the elastic member slides relative to the cam member, such that the driven member may not be affected by the cam member, but continue driving the paper grabbing roller to rotate.
