## Abstract

A multifunction printer (MFP) and a stopper applied therein are provided. The MFP includes a body, a top cover and the stopper. The body has a paper conveyor path, a paper holder located in front of an entrance of the paper conveyor path and a first rotating axle located in the paper conveyor path. A first side of the top cover rotates about the first rotating axle to be close to the paper holder. The stopper has a second rotating axle connected to the body, a connecting portion and an eccentric portion. The connecting portion is connected between the second rotating axle and the eccentric portion. The eccentric portion hangs down at the entrance of the paper conveyor path. A center of gravity of the stopper is located in the eccentric portion. A first stopping point of the top cover is located in a rotating path of the eccentric portion.

## Claims

### Claim 1

A multi-function printer (MFP), comprising:
a body, having a paper conveyor path, a paper holder and a first rotating axle, wherein the paper holder is located in front of an entrance of the paper conveyor path, and the first rotating axle is located in the paper conveyor path;
a top cover, disposed on the body, wherein a first side of the top cover is adapted to rotate about the first rotating axle so as to be close to the paper holder of the body, and the top cover has a first stopping point; and
a stopper, having a second rotating axle, a connecting portion and an eccentric portion, wherein the second rotating axle is connected to the body, the connecting portion is connected between the second rotating axle and the eccentric portion, the eccentric portion hangs down at the entrance of the paper conveyor path, a center of gravity of the stopper is located in the eccentric portion, and the first stopping point is located in a rotating path of the eccentric portion, so as to limit the rotation of the eccentric portion;
wherein when the first side of the top cover rotates about the first rotating axle so as to be close to the paper holder, the first stopping point releases the limitation to the eccentric portion, and the eccentric portion is adapted to rotate clockwise about the second rotating axle.

### Claim 2 (depends on 1)

The MFP according to claim 1, wherein the top cover further comprises a second stopping point, and a first end of the eccentric portion that is kept relatively away from the entrance is located between the first stopping point and the second stopping point.

### Claim 3 (depends on 2)

The MFP according to claim 2, wherein when the first side of the top cover rotates about the first rotating axle so as to be close to the paper holder, the eccentric portion is adapted to rotate clockwise about the second rotating axle, and the second stopping point limits a rotation angle of the stopper.

### Claim 4 (depends on 1)

The MFP according to claim 1, further comprising a paper feed roller, disposed on the top cover, wherein when the first side of the top cover rotates about the first rotating axle so as to be close to the paper holder, the paper feed roller contacts multiple pieces of paper placed in the paper holder, and the paper feed roller rotates to propel the paper to enter the paper conveyor path via the entrance of the paper conveyor path.

### Claim 5

A stopper, adapted to be disposed in a multifunction printer (MFP), for stopping paper from entering a paper conveyor path of the MFP, wherein the stopper has a rotating axle, a connecting portion and an eccentric portion, the rotating axle is adapted to be connected to a body of the MFP, the connecting portion is connected between the rotating axle and the eccentric portion, and a center of gravity of the stopper is located in the eccentric portion.
