Abstract
The present invention provides a sheet feeding apparatus with a regulating guide disposed along a sheet feeding path and adapted to regulate a position of a lateral edge of a sheet, first and second rotary members for feeding the sheet along the sheet feeding path and for applying force to the sheet to urge the lateral edge of the sheet against the regulating guide, and a support device for supporting the first and second rotary members in such a manner that they can be shifted in response to reaction force corresponding to the aforementioned force and received from the sheet.
Claims35
A sheet feeding apparatus, comprising:
- regulating means disposed along a sheet feeding path for regulating a position of a lateral edge of a sheet;
- first rotary means and second rotary means for feeding the sheet along said sheet feeding path, said first rotary means applying a force to the sheet to urge the sheet lateral edge against said regulating means;
- and
- support means for supporting said first rotary means and second rotary means;
- wherein one of said first rotary means and said second rotary means shifts away from said regulating means when the sheet is in contact with said first rotary means, said second rotary means, and said regulating means while maintaining constant an angle between a rotational axis of the one of said first rotary means and said second rotary means, and said regulating means.

An image forming system, comprising:
- regulating means disposed along a sheet feeding path for regulating a position of a lateral edge of a sheet;
- first rotary means and second rotary means for feeding the sheet along said sheet feeding path, said first rotary means applying a force to the sheet to urge the sheet lateral edge against said regulating means;
- support means for supporting said first rotary means and said second rotary means;
- wherein one of said first rotary means and said second rotary means shifts away from said regulating means when the sheet is in contact with said first rotary means, said second rotary means, and said regulating means while maintaining constant an angle between a rotational axis of the one of said first rotary means and said second rotary means, and said regulating means;
- and
- image forming means for forming an image on the sheet fed by said sheet feeding means.

A sheet feeding apparatus, comprising:
- regulating means disposed along a sheet feeding path for regulating a position of a lateral edge of a sheet;
- rotary means for feeding the sheet along said sheet feeding path, and for applying a force to the sheet to urge the sheet lateral edge against said regulating means;
- and
- support means for supporting said rotary means;
- wherein said rotary means shifts away from said regulating means when the sheet is in contact with said rotary means and said regulating means so that a pressing force of the sheet to said regulating means does not become too large, while maintaining constant an angle between a rotational axis of said rotary means and said regulating means.

An image forming apparatus, comprising:
- regulating means disposed along a sheet feeding path for regulating a position of a lateral edge of a sheet;
- rotary means for feeding the sheet along said sheet feeding path, and for applying a force to the sheet to urge the sheet lateral edge against said regulating means;
- support means for supporting said rotary means;
- wherein said rotary means shifts away from said regulating means when the sheet is in contact with said rotary means and said regulating means so that a pressing force of the sheet to said regulating means does not become too large, while maintaining constant an angle between a rotational axis of said rotary means and said regulating means;
- and
- image forming means for forming an image on the sheet fed by said rotary means.
3 more elements
A sheet feeding apparatus, comprising:
- a regulating member disposed along a sheet feeding path for regulating a position of a lateral edge of the sheet;
- and
- a rotary member for feeding the sheet along the sheet feeding path, and applying a force to the sheet in a direction to press it onto said regulating member;
- wherein said rotary member shifts away from said regulating member while keeping constant angular alignment when the sheet is in contact with said rotary member and said regulating member.
