<p>PURPOSE:To ensure the separation of the top sheet by providing an air sucking part in a part corresponding to stacked sheets of a cylinder shaft connected to an air sucking means, and forming ventilating parts successively communicating with the air sucking part on a paper feed roller held by the cylinder shaft and rotated. CONSTITUTION:One end of a cylinder shaft 18 transversely laid on a paper feed part 9 is clogged by a cap 19, and a suction blower 20 is connected on the other end side. In the middle part of the cylinder shaft 18, a large diameter part 19a shorter in length than the sheet width of a minimum size is formed, and in a part corresponding to the stacked sheets in a paper feed cassette set in the paper feed part 9, a slit air sucking part (a) is formed. On the outer diameter part of the large diameter part 18a of the cylinder shaft 18, a paper feed roller 25 is rotatably held by the cylinder shaft 18, and slit ventilating parts (b) successively communicating with the sucking part (a) in accordance with the rotation are formed circumferentially at fixed intervals. Thus, the paper feeding force is given to the sheets by the rotation of the paper feed roller 25 in the paper feeding direction, and the top sheet is sucked to form an air layer with the second sheet, and separated as being peeled.</p> |
