Abstract

An apparatus was designed for pages pick-up on bound documents by means of rubber friction. The apparatus is used as the kernel technique on several types of page turning system. The proposed mechanism picked the pages by a longitudinal rotating rubber-camshaft orthogonally across the documents. Friction of the rubber-camshaft rolled-up the unbounded edge of paper when the rubber-camshaft spinning tightly on the paper surface and lifted up these topmost pages to the upper-side of the shaft. The pages then could be removed to the opposite side of the bound documents by the device. A reliable apparatus is also designed.
