Abstract

PURPOSE: To carry sheets smoothly even when the piled sheets decrease by a method wherein a curved-surfacelike movable guide member is joined by a pin to a connecting member which makes vertical parallel movement, gearing with the vertical motion of a paper-feeding roller which is a means for detecting the surface of paper.
CONSTITUTION: With the decrease in piled sheets S, a paper-feeding roller lowers, while a connecting member 10 coupled with a shaft 4a also lowers without shaking, being guided by a groove provided in the vertical direction. Moreover, the guiding plate 9a of a movable guiding means 9, with its end part on the side of sheet connected with the connecting member 10, is kept in the lower position than the top sheet, and thus the sheets are carried smoothly in spite of their decrease. On the other hand, the guiding palte 9a is formed to have a gently curved surface and, in addition, is joined to the pin 15 of the end part 7a of a carrying plate through an arc-shaped long hole 12, and further the end part 7a of the carrying plate is formed to have a curved surface smaller in curvature than the one of the guiding plate 9a, which also facilitate smooth carriage.
