Abstract
A sheet feed device for use in a sheet counter arranged to separate stacked sheets one by one and to count the number of sheets. The sheet feed device has a feed roller having on its circumference a roller surface including a friction surface and a non-friction surface and a feed shaft, and at least one sheet separating member having a separation surface disposed so as to face the roller surface. Stacked sheets are separated one by one by the cooperation of the feed roller and the sheet separating member. The roller surface of the feed roller is formed so as to have a concave circular-arc sectional shape, and the separation surface of the sheet separating member is formed so as to have a convex circular-arc sectional shape. A gap is formed uniformly between the circular-arc surfaces formed in the roller surface and the separation surface, and the sheet separating member is disposed so that the uniform gap has a certain length along the circumferential direction of the feed roller.
