摘要

A sheet accumulating apparatus accumulates inputted sheets into a stack registered on all sides, wherein the sheets are controlled with minimum contact by components of the apparatus to minimize or eliminate smudging or marking of the sheets. The apparatus can be selectively adjusted to effect over-accumulation or under-accumulation, and can be adjusted to accommodate different sheet sizes. The apparatus comprises an accumulation section (20) defining a sheet feed plane therethrough. An upper ramp (59) is disposed upstream from the accumulation section and is movable into and out of the sheet feed plane. An upper retaining member (63) is linked to the upper ramp and is movable into and out of the sheet feed plane in alternating relation to the upper ramp. A lower ramp (61) is disposed below the upper ramp (59) and is movable into and out of the sheet feed plane in alternating relation to the upper ramp. A lower retaining member (65) is linked to the lower ramp and movable into and out of the sheet feed plane in alternating relation to the upper ramp. IMAGE
