Abstract
A document feeding apparatus is used in an office machine in the present invention. The document feeding apparatus includes an intermittent gear set, a first roller, a second roller, and a driving device. The intermittent gear set includes a gear, a shaft, a one-way spring clutch, an arcuate groove, and a pin. The intermittent gear set selectively drives the first roller to rotate so that the first roller conveys the document selectively. The present invention keeps in separation of the document from a next feed-in document and prevents the documents from overlapping.
Claims7
An intermittent gear set comprising:
- a gear rotating selectively in a first direction;
- a one-way clutch fixed to and selectively rotatable with said gear;
- a shaft fixed to and rotatable with said one-way clutch in said first direction;
- at least one arcuate groove located at a predetermined position on an operation face rotatable with said gear;
- and
- at least one pin parallel fixed with said shaft, relative to said arcuate groove and being disposed in and selectively movable in said arcuate groove;
- wherein said intermittent gear set operates between a first state for said pin retaining against a first end of said arcuate groove and a second state for said pin retaining against a second, end of said arcuate groove.
An document feeding apparatus comprising:
- an intermittent gear set including a selective rotatable gear, a one-way clutch fixed to and selectively rotatable with said gear;
- a shaft fixed to and rotatable with said one-way clutch, at least one arcuate groove located at a predetermined position on an operation face rotatable with said gear, and at least one pin parallel fixed with said shaft, relative to said arcuate groove and being disposed in and selectively movable in said arcuate groove;
- a first roller being fixed to and rotatable with said shaft to convey a document from a first position to a second position;
- a second roller conveying said document at said second position forward;
- and
- a driving device providing a power to drive said gear and said second roller to rotate;
- wherein said intermittent gear set operates between a first state and a second state, and defines an intermittent time during which the intermittent gear set changes states from the first state to the second state while the first roller stops rotating, resulting in separation of the document from the next-feed in document.
