Abstract

A sheet takeout mechanism has a takeout roller that rotates in contact with a sheet located at a takeout position, and a motor that intermittently rotates the takeout roller. A triangular suction port is formed on a suction surface of the takeout roller and has a vertex located downstream in a rotation direction of the takeout roller. When a negative pressure is exerted on the sheet via the suction port, the suction force is weak at the beginning of suction and then increases gradually.
