Claim 3
Dependent Claim
54 words
Paper feeding mechanism as claimed in claim 1, comprising further a guiding and positioning rod parallel to said bar and fixed to said frame and wherein each of said positioning and guiding elements comprises an arm coupled to said rod and movable along said rod, and means for locking said arm to said rod.
Claim 4
Dependent Claim
28 words
Paper feeding mechanism as claimed in claim 1 wherein said friction means comprises at least a resilient ring mounted on the outer surface of the related feeding element.
