Gear assembly of laminating apparatus

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 push device comprises
• a push element comprising a guiding track having a sustaining slant portion with a maximum thickness greater than a clearance of a gap between said movable gear at said object laminating position and a supporting plate at a side of said movable gear opposite to said urging device;
• and
• a sliding member protruding from said supporting plate and slidable relative to said guiding track for inserting said sustaining slant portion into said gap so as to push said movable gear toward said object releasing position while urging against said urging device.

A laminating apparatus, comprising:

• a pair of rollers for feeding an object through a laminating passage;
• a pair of fixed gears coupled to said pair of rollers capable of rotating said rollers;
• a motor capable of providing a driving force;
• a transmission shaft capable of rotating in response to said driving force;
• a movable gear coupled to and capable of rotating with said transmission shaft, capable of engaging with and causing said pair of fixed gears to rotate in an object laminating mode, and capable of disengaging from said pair of fixed gears in an object releasing mode by moving along the axial direction of said transmission shaft;
• a supporting plate disposed between said pair of rollers and said fixed and movable gears;
• a push element comprising a guiding track and having a sustaining slant portion with a maximum thickness greater than a clearance of a gap between said movable gear and said supporting plate;
• and
• a sliding member protruding from said supporting plate and capable of sliding relative to said guiding track to insert said sustaining slant portion into said gap so as to push said movable gear to disengage from said pair of fixed gears.
