发明名称 SHEET CONVEYOR FOR ELECTROPHOTOGRAPHIC PRINTER
摘要 <p>PURPOSE:To keep off any printing failure due to speed variations in a sheet conveying part being caused immediately after print starting by installing a rotary brake shaft in a buffer turning shaft, and making a buffer lighter in weight. CONSTITUTION:A rotary braking device 14 consists of a brake ring 15, a on-way clutch 16 and a screw 17, and two clutches 16 are inserted into this ring 15 so as to differ in a direction of rotation. Therefore only one side of the one-way clutches is rotated by the rotational direction of a shaft 12. Utilizing rotation in this one-side only if the clutches 16 are clamped by screws 17-a, 17-b from top of the ring 15, separate brake forces are giveable to turning effort in both directions by a difference of clamping force between both screws 17-a and 17-b, and this brake force absorbs impact energy. Moreover, with one sheet of buffers removed, sharp lightweightiness in a printer is well promoted. Thus, character blurredness is almost prevented from occurring.</p>
