Computer form web document unfolding and feeding assistance system

In a document feeding system for an imaging apparatus with an imaging station and a document input stacking area having front and rear facing sides, with an unfolding assistance system for unfolding and feeding to said imaging station an elongated web multi-sectional computer form document from a fan-folded stack thereof placed in said input stacking area in a feeding direction transversely of said front and rear facing sides extending generally horizontally from one end of said fan-folded stack towards said imaging station;

• wherein said document input stacking area and said imaging station are at substantially the same level, the improvement in said unfolding assistance system comprising:
• a mounting system mounting said unfolding assistance system adjacent said rear side of said document input stacking area,
• a smoothly radiused document unfolding assistance bar cantilever mounted to said mounting system and horizontally rotatable on said mounting system between a non-obstructing storage position adjacent said rear side of said document input stacking area and a stationary operating position overlying said document input stacking area, and
• a detent system for detaining said document unfolding assistance bar in said stationary operating position,
• said stationary operating position of said document unfolding assistance bar being in a selected fixed position substantially spaced above said document input stacking area and said fan-folded stack and extending over said stack substantially perpendicular to said feeding direction in a position which is intermediately overlying said stack spaced closer to said one end of said stack than the opposite end of said stack and positioned for otherwise unobstructed unfolding and feeding of said elongated web computer form document up and over said document unfolding assistance bar towards said imaging station in said feeding direction.
