The paper feeding device includes a frame, a top cover, a set of gear chains, a power unit and a set of driving gears. The set of gear chains and the power unit are disposed on a side of the frame. The set of driving gears is disposed on the top cover. When the top cover is closed relatively to the frame, the set of driving gears interferes with the power unit, and the power unit provides a power to enable the set of driving gears to rotate, so as to drive the set of gear chains. When the top cover is opened relatively to the frame, the set of driving gears releases interference with the power unit and the set of gear chains, and the set of gear chains is at a free rotation status."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Paper feeding device and multi-function printer using the same","description":"A paper feeding device and a multi-function printer using the same are provided.
