Paper pushing mechanism and scanning device including the same

A paper pushing mechanism applied to a scanning device which has a paper outlet, the paper pushing mechanism comprising:

• a swinging arm disposed close to the paper outlet, the swinging arm having a connecting end pivotally connected to the scanning device, and a swinging end extending towards the paper outlet;
• a spring, two ends of the spring being respectively connected to the scanning device and the swinging arm;
• a first ejecting roller disposed close to the paper outlet;
• a second ejecting roller disposed close to the paper outlet;
• a first pushing roller pivotally connected to the swinging end of the swinging arm;
• a second pushing roller disposed near the paper outlet;
• and
• a transmission mechanism connected between the first ejecting roller and the first pushing roller, the transmission mechanism making the first pushing roller and the first ejecting roller rotate in the same direction.

A scanning device, comprising:

• a frame equipped with a driving motor disposed inside the frame;
• a feeding path accommodated within the frame, the feeding path having at least one paper inlet and a paper outlet;
• at least one paper feeding roller mounted to the feeding path, and the at least one paper feeding roller being connected to the driving motor;
• a scanning unit disposed to a top and a bottom of the feeding path to read image media;
• a first ejecting roller disposed to the feeding path, the first ejecting roller being disposed close to the paper outlet, the first ejecting roller being positioned at a lower side of the feeding path, and the first ejecting roller being connected to the driving motor;
• a second ejecting roller disposed to the feeding path, the second ejecting roller being disposed close to the paper outlet, the second ejecting roller being positioned at an upper side of the feeding path, and the second ejecting roller abutting against the first ejecting roller;
• a swinging arm disposed to the feeding path, the swinging arm being disposed close to the paper outlet, the swinging arm being positioned to the lower side of the feeding path, the swinging arm having a connecting end pivotally connected to the frame, and a swinging end extending towards the paper outlet;
• a spring, two ends of the spring being respectively connected with the frame and the swinging arm, so the swinging end being pushed towards the upper side of the feeding path;
• a first pushing roller pivotally connected to the swinging end of the swinging arm;
• a second pushing roller disposed to the feeding path, the second pushing roller being disposed near the paper outlet, the second pushing roller being positioned at the upper side of the feeding path, the second pushing roller abutting against the first pushing roller at the time of the swinging arm swinging upward;
• and
• a transmission mechanism connected between the first ejecting roller and the first pushing roller, the transmission mechanism making the first pushing roller and the first ejecting roller rotate in the same direction.
