Sheet feeding apparatus
First Claim
1. A sheet feeding apparatus comprising:
- a stacker for stacking a sheet material;
a feed roller for separating the sheet material stacked on said stacker;
a rotatable separation roller rotatable by being driven by said feed roller; and
a torque limiter for controlling rotation of said separation roller; and
wherein a second or subsequent sheet material staying in a nip between said feed roller and said separation roller is separated from said separation roller by a rotational direction of said feed roller being changed from a forward rotational direction to a backward direction and by a rotational direction of said separation roller being changed to a backward direction by said feed roller during a first sheet material which is in contact to said feed roller being nipped by said nip; and
a first sheet material is fed toward downstream of said nip by the rotational direction of said feed roller being changed from the backward direction to the forward direction.

Abstract
A sheet feeding apparatus includes stacker for stacking a sheet material; a feed roller for separating the sheet material stacked on the stacker; a rotatable separation roller rotatable by being driven by the feed roller; and a torque limiter for controlling rotation of the separation roller; wherein a second or subsequent sheet material staying in a nip between the feed roller and the separation roller is separated from the separation roller by a rotational direction of the feed roller being changed from a forward rotational direction to a backward direction and by a rotational direction of the separation roller being changed to a backward direction by the feed roller during a first sheet material which is in contact to the feed roller being nipped by the nip; and a first sheet material is fed toward downstream of the nip by the rotational direction of the feed roller being changed from the backward direction to the forward direction.
