Abstract:
A sheet feeding apparatus comprising:sheet supporting means movable for supporting a sheet or sheets; a sheet feeding rotary member in contact with the sheet supported by the sheet supporting means to feed out the sheet upon rotation of the feeding rotary member, and a separating rotary member forming a contact portion in contact with the feeding rotary member and being rotatable in a direction returning the sheet to separate the sheet fed out of the feeding rotary member one by one, wherein the sheet supporting means, the feeding rotary member, and the separating rotary member are so disposed that an angle formed on a side of the feeding rotary member by intersecting a tangential line of the feeding rotary member at a contacting position between the feeding rotary member and the sheet with a tangential line at the contact portion is an obtuse angle, and further comprising conveyance guiding means having a guide surface adjacent to the contact portion for guiding the sheet fed by the feeding rotary member to the contact portion, the conveyance guiding means having a projection guiding means projected a greater amount toward the feeding rotary member on an upstream side in the sheet conveyance direction of the contact portion than the guide surface and the conveyance guide means having an inclined portion more inclined toward the feeding rotary member on an downstream side in the sheet conveyance direction of the contact portion than the guide surface.
