DEVICE FOR DELIVERY OF PAPER SHEETS FOR AN APPARATUS FOR COUNTING THE NUMBER OF PAPER SHEETS

摘要

An apparatus for counting the number of paper sheets has a pair of feed-out auxiliary rolls rotatably mounted at the bottom of a hopper for advancing papper sheets stacked in said hopper towards a payout roll mounted in the neigborhood of a hopper outlet. Each auxiliary roll has a frictional surface forming a portion of the roll periphery and having a recessed peripheral zone any point of which is spaced from the center of the roll by a distance lesser than that by which any point on the periphery of a slippery surface forming the remaining portion of the roll periphery is spaced from the center of the roll. The paper sheets stacked in the hopper are moved vertically by the auxiliary rolls each having said recessed zone and advanced towards the payout roll with a larger force of friction by being contacted over a wider area with said frictional surface.
