bill is introduced into the aperture 8 the same is detected and a cycle of movement commences this cycle of movement includes in the first stage the operation of arms not shown which lie to either longitudinal edge of the bill respectively these arms are each spring loaded so as to be biased towards a longitudinal note edge and are moved in by the rotational movement of a cam mechanism driven by a motor these arms during this stage essentially grip the bill via the edges and as they do so encourage a sliding sideways movement of the bill as required in order to move the bill such that the longitudinal centre axis of the bill lies substantially parallel and in line with the longitudinal axis of the movement of the bill along the infeed mechanism this ensures that the bill is in the required position for accurate identification of the characteristics of the bill and the smooth movement of the bill through the apparatus as the cam moves so the first stage of movement changes to the second stage which is the movement of the bill through the infeed assembly to if the bill is valid the storage container as the change from the first to the second stage occurs the series of wheels which cause the movement of the bill are moved into contact along the longitudinal axis of the bill with the wheels in contact with the bill so the arms are removed from contact with the bill and so it will be appreciated that the bill is always in positive controlled contact with the infeed mechanism fig6 a and.
