Abstract
A paper discharging apparatus contains a movable mechanism and a control unit. The movable mechanism moves a surface part between a first position that the surface part is not contacted with a pinch roller and a second position that the surface part is contacted with the pinch roller through a paper so as to push the pinch roller; the control unit moves the surface part to the second position, clamps the paper by the pinch roller and the surface part, and conveys the paper, thereby bending the paper, and which moves the surface part to the first position and clamps the paper by the pinch roller and a feeding roller, and rotates the feeding roller, thereby discharging the paper from the conveyance path.
Claims10
A paper discharging apparatus, comprising:
- a paper conveyance path;
- a first conveying unit configured to convey a paper along the conveyance path;
- a second conveying unit including a pinch roller and a feeding roller that are arranged closer to the downstream side than the first conveying unit in the paper conveying direction, the pinch roller and the feeding roller clamping the paper therebetween and conveying the paper along the conveyance path;
- a movable mechanism, including a surface part having a specified shape, moving the surface part between a first position that the surface part is not contacted with the pinch roller and a second position that the surface part is contacted with the pinch roller through the paper and pushes the pinch roller until the pinch roller is separated from the feeding roller;
- and
- a control unit configured to move the surface part to the second position by the movable mechanism, wherein the paper is clamped by the pinch roller and the surface part and the paper is bent through conveying the paper by the first conveying unit under this state, then to move the surface part to the first position by the movable mechanism, wherein the paper is clamped by the pinch roller and the feeding roller and the paper is discharged from the conveyance path by rotating the feeding roller under this state;
- and wherein the control unit collects the paper into the housing of the paper discharging apparatus if a given period of time elapses in a state that the paper is at least partially exposed from a discharge port arranged on the housing.
An image forming apparatus, comprising:
- a paper conveyance path;
- a first conveying unit configured to convey a paper along the conveyance path;
- a second conveying unit including a pinch roller and a feeding roller that are arranged closer to the downstream side of the paper conveying direction than the first conveying unit, the pinch roller and the feeding roller clamping the paper therebetween and conveying the paper along the conveyance path;
- a printer unit configured to print on the paper;
- a movable mechanism, including a surface part having a specified shape, moving the surface part between a first position that the surface part is not contacted with the pinch roller and a second position that the surface part is contacted with the pinch roller through the paper and pushes the pinch roller until the pinch roller is separated from the feeding roller;
- and
- a control unit configured to move the surface part to the second position by the movable mechanism, wherein the paper is clamped by the pinch roller and the surface part and the paper is bent through conveying the paper by the first conveying unit under this state, then to move the surface part to the first position by the movable mechanism, wherein the paper is clamped by the pinch roller and the feeding roller and the paper is discharged from the conveyance path by rotating the feeding roller under this state;
- and wherein the control unit collects the paper into the housing of the paper discharging apparatus if a given period of time elapses in a state that the paper is at least partially exposed from a discharge port arranged on the housing.
