Abstract

In an ink supply device of a printing machine, an abutting pressure of doctor blades is adjusted and maintained to be an appropriate value. A position adjusting and fixing mechanism 7 comprises a first part for position adjusting and fixing 7a-1, a second part for position adjusting and fixing 7a-2 which are attached to a frame, and parts to be position-adjusted and fixed provided on a housing 20. The first part for position adjusting and fixing 7a-1 and the second part for position adjusting and fixing 7a-2 are movable between fixing positions in abutment with the parts to be position-adjusted and fixed and releasing positions of fixation separated from the parts to be position-adjusted and fixed respectively. The ink doctor chamber 2 is fixed so as not to move by fixing the first part for position adjusting and fixing 7a-1 and the second part for position adjusting and fixing 7a-2 at the fixing position, together with this, the abutting pressure of doctor blades 21 can be adjusted and maintained to be an appropriate value.
