    • PROBLEM TO BE SOLVED: To prevent different size manuscript sheets from being fed askew certainly when a bundle of such paper sheets is placed on a tray and fed, by installing a means to give an additional load pressure to a pickup roller itself in addition to a conventional load pressure applied by a pickup roller.
      SOLUTION: A sheet feeding device includes a pressure changing means 20 to change the load pressure of the pickup roller on a manuscript sheet, and the means 20 is equipped with a changeover lever 22 to change over the load pressure, a rotary lever 21 to abut to a swing arm 6 of the pickup roller and press it, and an energization part 23 to energize the lever 21 toward a support shaft when the lever 21 abuts to the swing arm 6. When a manuscript bundle containing manuscript sheets having different sizes in mixture is to be read continuously, the rotary lever 21 is abutted to the swing arm 6 by turning the changeover lever 22 by the user to cause the energization part 23 to press the swing arm 6, and thereby the load pressure on the manuscript sheet is increased.

    • 要解决的问题:为了防止当一捆这样的纸张放置在托盘上并进给时,通过安装一个装置给拾取辊本身提供额外的负载压力,防止不同尺寸的原稿被歪斜 除了由拾取辊施加的常规负载压力之外。 解决方案:片材进给装置包括:压力改变装置20,用于改变原稿上的拾取辊的负载压力,并且装置20装备有转换杆22以改变负载压力;旋转杆 21接触拾取辊的摆臂6并将其按压;以及通电部23,当杆21抵靠在摆臂6上时,通电部23向支撑轴施力。当包含不同的原稿片的原稿束 要连续读取混合物的大小,旋转杆21通过使用者转动切换杆22而与摆臂6抵接,使通电部23按压摆臂6,从而对原稿的负载压力 纸张增加。 版权所有(C)2007,JPO&INPIT
