Abstract
A document separating mechanism for an Automatic Document Feeder is an elastomer with the features of having a vertical plane and an arc surface, wherein the vertical plane is perpendicular to the main plane and capable of resisting the leading edges of the documents directly or indirectly. The arc surface is a turning plane for joining the vertical plane and the main plane. The document separating mechanism further includes the document guiding incline for making the documents being pressed by the feeding roller and arranged in order initially.
Claims15
A document separating mechanism for an Automatic Document Feeder, wherein the Automatic Document Feeder has a feeding roller for carrying documents forward, the document separating mechanism comprising:
- a main plane having a plurality of edges;
- a vertical plane, perpendicular to the main plane and capable of resisting the leading edges of the documents directly or indirectly;
- and
- an arc surface between the vertical plane and the main plane, wherein the arc surface joins the vertical plane and the main plane;
- wherein the document separating mechanism is an elastomer;
- and
- wherein the thickness of the document is substantially smaller than a half and greater than a quarter of the radius of curvature of the arc surface (0.25R<T<0.5R).
A document separating mechanism for an Automatic Document Feeder, wherein the Automatic Document Feeder has a feeding roller for carrying documents forward, the document separating mechanism comprising:
- a main plane;
- a vertical plane, perpendicular to the main plane and capable of resisting the leading edges of the documents directly or indirectly;
- and
- an arc surface between the vertical plane and the main plane, wherein the arc surface joins the vertical plane and the main plane;
- wherein the arc surface has a radius of curvature (R) that satisfies 0.25(R)<(T)<0.5(R), wherein T is a thickness of the document.
A document separating apparatus adapted for use with a feeding roller of an automatic document feeder, the feeding roller feeding documents in a downstream direction, comprising:
- a main plane;
- a vertical plane arranged perpendicular to the main plane for resisting leading edges of the documents, and being disposed upstream relative to the main plane;
- and
- an arc plane monolithically formed between the main plane and the vertical plane.
