A device for adjusting an ink supply gap is employed in an ink fountain apparatus in which the bottom portion of the ink fountain apparatus forms a space for storing ink in cooperation with a peripheral surface of an ink fountain roller while a forward edge of the bottom portion faces the peripheral surface of the ink fountain roller in order to form a gap serving as an ink supply port. The device for adjusting an ink supply gap includes a plurality of blade segments and a plurality of ultrasonic linear motors corresponding to the blade segments. The blade segments are disposed on a base in a row extending in the axial direction of the ink fountain roller and are adapted to individually advance toward or retract from the ink fountain roller so as to adjust the opening of the ink supply port. The ultrasonic linear motors are adapted to individually advance or retract the corresponding blade segments.
