Description

ABSTRACT:
Endless drive belts are provided in a spaced-apart relation to each other such that one endless driven belt is set in contact with one of these drive belts and the other endless driven belt is set in contact with the other drive belt. The one drive belt is driven by one pulse motor through one drive roller and that other drive belt is driven by the other pulse motor through the other drive roller. A bill is conveyed with its opposed edges gripped by the drive and driven belts. A controller measures the skew of the bill and bill-to-bill interval on the basis of output signals detected by forward-stage detecting units against the conveying bill and controls the respective rotational speeds of the one pulse motor and that other pulse motor on the basis of a result of measurement.
