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，用于与拾取辊配合以分离最下面的纸。 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 auto sheet feeder used for a device comprises an upper frame, a pick roller and a sheet separating mechanism secured on the upper frame. The sheet separating mechanism includes a bracket and a pair of arms disposed on the bracket and spring-biased toward the pick roller. A separator pad is disposed on the bracket and spring-biased toward the pick roller. A press plate is positioned on the bracket and presses against the separator pad. A torsion spring mounted above the press plate has at least two coil portions. Two adjacent ends of the coil portions extend toward the same side and then joint each other to form a contact portion which always props the upper frame. Two ends of the torsion spring have a retaining arm respectively. The two retaining arms are opposite each other and pivotally engage to two sides of the press plate respectively. The torsion spring is compressed by the press plate when the sheets push the separator pad and pushes the press plate and the separator pad to be reposition after the lowermost one of the sheets is separated.

Abstract: A digital visual interface dual-stack connector includes a holder base and a first connector and a second connector mounted in the holder base at different elevations, the second connector having multiple second terminal pins arranged in three sets and mounted in a slotted mating body portion of a housing thereof, each second terminal pin defining a vertical rear bonding portion, a horizontal front contact portion, an oblique support arm portion and two curved portions respectively connected between the vertical rear bonding portion and horizontal front contact portion and the two ends of the support arm portion. By means of controlling the bending angles of the two curved portions of the second terminal pins and the pitch between each two adjacent second terminal pins, the invention accurately achieves impedance matching to reduce high frequency signal reflection, enhancing signal transmission stability and reliability.
