Abstract:
1. A gear assembly of a laminating apparatus, comprising: a transmission shaft coupled to a motor; a movable gear adapted to rotate with said transmission shaft, wherein the moveable gear is adapted to slide along an axial direction of said transmission shaft between an object laminating position and an object releasing position; a fixed gear coupled to a roller, wherein the fixed gear is capable of engaging and rotating with said movable gear if said movable gear is at said object laminating position, and wherein the fixed gear is capable of disengaging from said movable gear if said movable gear is at said object releasing position; a push device capable of receiving an external force to slide said movable gear from said object laminating position to said object releasing position; and an urging device coupled to said movable gear, wherein the urging device is capable of pushing said movable gear back to said object laminating position in response to said external force being released from said push device; wherein said urging device comprises an elastic element capable of being in contact with said movable gear and capable of providing a restoring force if said elastic element is compressed by said movable gear; and wherein said urging device comprises a coil spring sleeved around said transmission shaft and disposed at a side of said movable gear.
