Abstract
In a printing machine of the type wherein the quantity of ink is adjusted by varying a gap between an inking roller and an adjusting piece there are provided an actual position representing unit which stores a data corresponding to a gap width, a reference position setting unit for the adjusting piece at which the ink does not leak out, a comparator comparing outputs of the actual position representing unit and the reference position setting unit, an inking roller rotating state judging unit which produces a stop signal when the inking roller stops, and a gate circuit responsive to the stop signal and the output of the comparator for moving the adjusting piece. The control circuit is constructed to maintain the adjusting piece at the reference position when the inking roller is stopped.
