Document feeder

A document feeder for advancing a document along a defined path within an office machine comprising:

• frame means for supporting the document,
• a first document feed member positioned adjacent a first side of the path, and rotatably mounted on said frame means to urge the document along the path,
• a second document feed member positioned adjacent a second side of the path, and rotatably mounted on said frame means to urge the document along the path,
• a lever means pivotally supporting each of said feed members on said frame means for affording the independent angular adjustment of each of said feed members with respect to the adjacent side of the path and including:
• a shaft mounted within said frame means generally transverse to the path,
• a first arm extending generally parallel to the adjacent side of the path, said first arm having an aperture therethrough disposed toward one of its ends, said first arm being pivotally mounted on said shaft with said shaft passing through said aperture and thereby serving as a fulcrum for said first arm,
• a second arm projecting at an angle from said first arm and disposed generally parallel to said shaft,
• a third arm extending at an angle from said second arm, said third arm having a first slot therethrough disposed with its longitudinal axis lying in a plane parallel to the plane in which said feed member is to pivot and adapted to receive said shaft, and a second slot with its longitudinal axis parallel to the longitudinal axis of said first slot, said second slot being spaced from said first slot in a direction away from the document path,
• means for adjusting the angular separation between said first arm and said shaft, thereby pivoting said first arm about said fulcrum and changing the angular orientation of said feed member with respect to the path, and
• means for biasing said feed members into contact with the document including a rod adapted to slideably engage said second slots of said third arms, and a spring connected between said rod and said frame means, whereby said rod can slide within said second slots to permit the independent angular adjustment of each of said lever means and yet afford the separate biasing of each of said lever means toward the document.
