    • Provided are an apparatus for feeding sheets, booklets or the like having a wider adjustable range according to the thickness of the object than the conventional apparatus, and a system for sorting forwarding documents with the foregoing feeding apparatus. In the feeding apparatus, a moving shaft is supported by a fixed sleeve so as to be movable upward and downward. A main compression coil spring is located between the moving shaft and the fixed base and imparts a main spring force to the moving shaft in order that an overlap feed limiting member is pressed against a conveying belt. A sub compression coil spring imparts an oppositely directed sub spring force to the moving shaft. A position of a pressing washer is displaced downward by a threading engagement of an upper end adjusting bolt, so that even when the spring force of the main compression coil spring is increased, an increased amount is cancelled by an increase in the spring force of the sub compression coil spring.
    • 提供了一种用于馈送具有比常规装置的物体厚度更宽的可调节范围的片材,小册子等的装置,以及用于与前述馈送装置分类转发文件的系统。 在进给装置中,移动轴由固定的套筒支撑,以便能够上下移动。 主压缩螺旋弹簧位于移动轴和固定基座之间,并向主动弹簧施加主弹簧力,以便将重叠进给限制构件压靠在输送带上。 副压缩螺旋弹簧向移动轴施加相反方向的副弹簧力。 通过上端调节螺栓的螺纹接合,按压垫圈的位置向下移位,使得即使当主压缩螺旋弹簧的弹簧力增加时,增加的量也由于弹簧力的增加而被抵消 副压缩螺旋弹簧。

    • A torque limiter between a pressure roller and shaft, which is configured to allow the pressure roller to rotate in a feed-out direction of a paper-sheet P, relative to the shaft, when force greater than predetermined torque T is applied to the pressure roller along a circumferential direction thereof, while interlocking the pressure roller with the shaft, when the force applied to the pressure roller along the circumferential direction thereof is less than the predetermined torque. The predetermined torque is set less than frictional force N3 directly generated between a feed roller friction part and a pressure roller friction part at a nip part N, while being set greater than both of frictional force N1 generated between the pressure roller friction part of the pressure roller and the paper-sheet P at the nip part N and frictional force N4 generated between a pair of paper-sheets P at the nip part.

    • This sheet multifeed determination device is capable of accurately detecting a sheet multifeed state, and the sheet multifeed determination device includes: a separating member side sheet speed detecting part which detects a transport speed of a sheet surface on the separating member side of a sheet transported to a nip unit of a paper feed roll and a separating member pressure-contacting mutually; a multifeed sheet detecting part which detects presence of plural sheets in the course of being transported through the nip unit; and a multifeed state determination part which determines not to be in a multifeed state of sheets when the sheet speed detected by the separating member side sheet speed detecting part is V2≦0 and determines to be in the multifeed state of sheets in the case of V2>0 in a condition where the multifeed sheet detecting part detects multifed sheets.
