Description of the Invention: The present invention relates to an automatic paper feeding device, and more particularly to an automatic paper feeding device having a clutch for controlling a paper feeding program. • [Prior Art] ^ The pick-up automatic paper feeding device used in the conventional scanner usually includes a pickup roller, a separation roller, and a plurality of paper conveying rollers φ wheels. The pickup roller must be driven to move up and down to grab the paper for the separation roller feed. Since the combination of the pickup roller and the separation roller needs to be intermittently rotated, and the combination of the paper conveying rollers must be continuously rotated, the combination of the pickup roller and the separation roller must be driven separately from the combination of the paper conveying rollers. To achieve this, two motors can be used to separate the combination of the vine pick-up roller and the separation roller and the paper transport roller I combination, but the cost of the product is greatly increased. Therefore, the conventional practice is usually to achieve a separate driving effect by a gear clutch device.
