Abstract
Featured is a sheet feed unit including a first transport path in which is transported a first sheet, a second transport path and a protrusion. A second sheet is transported in the second transport path and guided at a prescribed angle relative to the first transport path. The protrusion is located or fixed at a confluence of the first transport path and the second transport path. The protrusion also has a guide surface that is placed to allow the second sheet to be guided along the first transport path.
Claims19
A sheet feed unit comprising:
- a first transport path which transports a first sheet from a first source;
- a second transport path which transports a second sheet from a second source guided at a prescribed angle relative to said first transport path;
- and
- a protrusion fixed at a confluence of said first transport path and said second transport path and being fixed to said first transport path, said protrusion having a curved guide surface placed on an extended line of a guide surface of said second transport path to transport said second sheet along said first transport path in substantially the same direction as said first sheet.

A sheet feed unit comprising:
- a first transport path which transports a first sheet from a first source;
- a second transport path which transports a second sheet from a second source guided at a prescribed angle relative to said first transport path;
- and
- a first guide, said first guide being formed and fixed in said first transport path and having a concave guide surface placed at a confluence of said first transport and said second transport path, wherein said concave guide surface is placed on an extended line of a guide surface of said second transport path to transport said second sheet along said first transport path in substantially the same direction as said first sheet.
1 more element
A sheet feed unit comprising:
- a first transport path which transports a first sheet from a first source;
- a second transport path which transports a second sheet from a second source at a prescribed angle relative to said first transport path;
- and
- a guide fixed in said first transport path and placed at a location where said second sheet transported through said second transport path meets said first transport path and at a portion facing said second transport path, said guide having a curved guide surface placed on an extended line of a guide surface of said second transport path to transport said second sheet along said first transport path in substantially the same direction as said first sheet.
1 more element
A sheet feed unit comprising:
- a first transport path which transports a sheet from a first source of sheets substantially in a vertical direction;
- a second transport path which transports a sheet from a second source of sheets at a prescribed angle relative to said first transport path;
- a confluence at a location where the sheet transported through said second transport path meets said first transport path;
- and
- a concave portion placed at said confluence and fixed in said first transport path, said concave portion having a curved guide surface placed on an extended line of a guide surface of said second transport path to transport the sheet being transported through said second transport path along said first transport path in substantially the same direction as the sheet that would be transported in said first transport path.
2 more elements
A sheet feed unit comprising:
- a first transport path which transports a sheet from a first source of sheets substantially in a vertical direction;
- a second transport path which transports a sheet from a second source of sheets at a prescribed angle relative to said first transport path;
- a guide constituting said first transport path;
- a guide surface placed at said guide corresponding to a location where sheets transported through said first and second transport paths meet, said guide surface being shaped into a curve, wherein said curved guide surface is placed on an extended line of a guide surface of said second transport path to transport the sheet being transported through said second transport path along said first transport path in substantially the same direction as the sheet that would be transported in said first transport path;
- and
- wherein said guide is formed of a plurality of guide ribs and said guide surface shaped into the curve is integrally formed with said guide ribs.
