Abstract
A feed roller and a separation roller each having convex portions are arranged so that the convex portions engage with each other. A lever is provided such that one end of the lever is fixed to a rotatable shaft and other end slides on a shaft around which the separation roller rotates. The other end has at least two portions with different radii of curvature. A knob is integrally connected to the lever. When a user operates the knob, the lever rotates and the shaft around which the separation roller rotates is pushed away depending on the radii of curvature of the portion of the lever so that amount of engagement between the feed roller and the separation roller changes.
