    • A system for reliably feeding individual sheets of recording media is disclosed especially as such system is related to media suitable for electrosensitive recording such as in a facsimile or other device. According to a preferred embodiment, such system may comprise scanning means; sheet storage means; a stack of sheets in said storage means; sheet separating means adapted to successively contact the uppermost of said sheets in said stack as said uppermost sheets are removed from said stack, said separating means including a surface in frictional engagement with an uppermost sheet surface of said stack; drive means for moving said surface in a direction substantially parallel to the sheets in said stack so as to pull each of said uppermost sheets from said stack in a direction generally parallel with the uppermost sheet in said stack, said pulling force being substantially equal on each of the uppermost sheets and sufficient to overcome the frictional force between the uppermost sheets and the sheets beneath the uppermost sheets; each of said sheets in said stack carrying an antistatic electricity additive for substantially minimizing the electrostatic attractive force between said sheets so as to substantially equalize said pulling force required to separate the uppermost sheets from the sheets beneath regardless of atmospheric conditions; and means for transporting said sheets from said storage means to said scanning means.
    • 特别地公开了一种用于可靠地馈送单张记录介质的系统,因为该系统与适合于诸如传真机或其它设备之类的电敏记录的介质有关。 根据优选实施例,这种系统可以包括扫描装置; 纸张存储装置; 所述存储装置中的一叠纸张; 片材分离装置适于在所述堆叠中从所述堆叠中移除所述最上面的片材时连续接触所述堆叠中的最上面的片材,所述分离装置包括与所述堆叠的最上面的片材表面摩擦接合的表面; 驱动装置,用于沿着与所述堆叠中的片材基本上平行的方向移动所述表面,以便在大体上平行于所述堆叠中的最上面的片材的方向上将所述最上面的片材从所述堆叠中拉出,所述拉力在每个上基本相等 并且足以克服最上面的片材与最上面的片材之下的片材之间的摩擦力; 所述堆叠中的每个所述片材携带抗静电电力添加剂,用于基本上使所述片材之间的静电吸引力最小化,从而基本上使得将最上面的片材与片材分开所需的所述拉力大致相等,而不管大气条件如何; 以及用于将所述片材从所述存储装置传送到所述扫描装置的装置。
