A sheet ejection mechanism including a sheet ejection roller capable of rotating along a selective direction and having an arc portion and a plane portion, the arc portion and the plane portion forming a D-shape cross-section, and a pinch member configured at a position adjacent to the sheet ejection roller, wherein a recording medium is clamped and conveyed between the pinch member and the arc portion of the sheet ejection roller, and a gap is formed between the plane portion and the pinch member for allowing the recording medium to pass. Also, the present invention provides a duplex sheet feeding system having the sheet ejection mechanism.

Sheet ejection mechanism and duplex sheet feeding system having the sgeeet ejection mechanism

A sheet feeding mechanism having a pickup roller, a switch device, and a gear set is disclosed. The pickup roller drives a recording material to a first path, and the recording material proceeds from the first path to a second path or from a third path to a fourth path when the switch device is switched to a first position, and proceeds from the first path to the third path when the switch device is switched to a second position. The gear set drives the recording material from the first path to the third path when the switch device is switched to the second position and drives the recording material from the first path to the second path, from the third path to the fourth path, and from the fourth path to the first path when the switch device is switched to the first position.
