Abstract: A sheet feeding device includes a pick roller and a resilient element disposed above the pick roller. The pick roller has a roller surface. The resilient element includes two side resilient arms and a center resilient arm located between the two side resilient arms. Free ends of the two side resilient arms are pushed forward by all sheets when the sheets arrive between the free ends of the two side resilient arms and the roller surface. A free end of the center resilient arm faces the roller surface of the pick roller and maintains a gap therebetween. When too many pieces of paper are drawn forward to the resilient element, the side resilient arms are pushed forward further more, the uppermost paper contacts the center resilient arm. The center resilient arm cooperates with the side resilient arms to provide the paper a pressure big enough to be conveyed forward.

Abstract: A paper feeding device includes a pick roller, a spring element and a separator pad. The pick roller has a roller surface. The spring element is disposed above the pick roller. The spring element has two spring arms extending toward two ends of the pick roller. Free ends of the two spring arms extend to positions outside the two ends of the pick roller and below the roller surface so as to be contactless with the roller surface and are pushed forward and upward by papers and then transfer a press force to the pick roller. A separator pad is arranged in front of the spring element and contacts with the roller surface of the pick roller for cooperating with the pick roller to separate a lowermost one of the papers. Because the spring arms are contactless with the pick roller directly, so the spring arms do not rub the pick roller, which avoids the pick roller being abraded.

Abstract translation: 送纸装置包括拾取辊，弹簧元件和分隔垫。 拾取辊具有辊表面。 弹簧元件设置在拾取辊上方。 弹簧元件具有两个朝拾取辊的两端延伸的弹簧臂。 两个弹簧臂的自由端部延伸到拾取辊的两端的外侧并且在辊表面下方的位置，以便与辊表面无接触，并被纸向前和向上推动，然后将压力传递到拾取辊 。 分离器垫布置在弹簧元件的前面并与拾取辊的辊表面接触，以与拾取辊协作以分离最下面的纸。 因为弹簧臂与拾取辊直接接触，所以弹簧臂不要搓动拾纸辊，这样可以避免拾纸辊磨损。

Abstract: An optical scanning device with a dustproof function includes a shell defining a first receiving room and a second receiving room communicating with the first receiving room through an open window defined on the shell for scanning light beams passing therethrough. An optical scanning module is mounted in the first receiving room. A glass platform is located on the second receiving room at a position facing the open window for insulating the first receiving room from the outside of the shell. A correcting plate is stuck on the bottom of the glass platform. Such structure of the optical scanning device enables the glass platform to be firstly assembled with the shell in a dustless chamber, which prevents the suspending dust from falling in the first receiving room and attaching to the optical scanning module during the subsequent assembly process and ensures the scanning quality of the optical scanning device.

Abstract: A pickup mechanism includes a main frame, a supporting element mounted to the main frame, and a pickup module positioned in the main frame and including a pickup arm, a transmitting element, a separation element, a pickup element and a barrel element. The separation element includes a separation shaft and a separation roller. The pickup element includes a pickup shaft and a pickup roller. The separation roller and the pickup roller are restricted in the pickup arm. The transmitting element links the separation shaft and the pickup shaft. The pickup arm is pivoted at the separation shaft. The barrel element has a base portion pivotally mounted around the pickup shaft, and a stopping block. When the pickup module swings upward or downward, the barrel element is driven to rotate along with the pickup shaft to make the stopping block against the supporting element or apart from the supporting element.

Abstract: A belt drive mechanism with belt tensioner has a driving pulley pivoted to a fixing frame, a driven pulley pivoted to the fixing frame, with a belt wrapping thereon, and a tensioner which has a wheel pivoted to a mounting block of the fixing frame and rests against the running belt, and a cap rotatably covered to a top of the wheel. The cap has a through hole engaged with the mounting block and is capable of moving along a direction substantially perpendicular to a running direction of the belt at a contact position with the wheel. An elastic element is mounted between the mounting block and an inner side of the through hole and compressed by the moved cap to store an elastic force which releases to bring the wheel to press the running belt away from the mounting block for compensating a tensile force of the running belt.

Abstract: The present invention provides a multiple documents feeding detection mechanism includes an advancing roller applying a driving torque, a retarding roller applying a resisting torque and connected to the advancing roller for transporting pieces of documents, and a detecting means. The friction of a surface of the advancing roller, the friction of a surface of the retarding roller, the driving torque and the resisting torque are tuned to urge the retarding roller either into rotation while one signal document fed into a nip between the advancing roller and the retarding roller, or in standstill while multiple document fed into the nip. The detecting means determines whether the multiple documents feeding is caused by monitoring an action of the retarding roller.
