Patent ID: 7011130

Claim:
An apparatus for connecting portions of a circuit board on an interior of a hollow core roller to at least one external contact, said roller having a first end rotatably supported on a frame, a non-rotating tubular shaft supporting a second end of the roller for rotation relative to the frame and the tubular shaft having an end surface open to an interior of the hollow core roller, a first spring exerting a load in an axial direction on the hollow core roller toward the first end of the hollow core roller, a circuit board supported on the interior of the hollow core roller adjacent the second end of the hollow core roller, said circuit board having a plane that is generally perpendicular to an axis of rotation of the hollow core roller, a first support axially fixed on the interior of the hollow core roller and spaced inwardly from the circuit board, a second support slidably mounted on the interior of the hollow core roller to an interior side of the circuit board, a second spring engaging the first support and loading the second support toward the circuit board and tubular shaft to engage the circuit board and urge the circuit board to engage the end of the tubular shaft to thereby effect a signal carrying connection between a first contact region of the circuit board and the tubular shaft.
