Inking device of numbering and imprinting machine

An inking device of a numbering and imprinting machine, the inking device being configured to feed inks stored inside an ink fountain onto a numbering cylinder configured to print a code onto a transported sheet, the inking device comprising:

• a numbering unit provided on an outer peripheral portion of the numbering cylinder and configured to print a code onto a transported sheet;
• a partition member configured to partition an inside of the ink fountain in such a manner that inks of a plurality of colors are stored divided by the colors inside the ink fountain;
• an ink fountain roller configured to draw out the inks of the plurality of colors stored in the divided manner inside the ink fountain, in such a manner that the inks appear side by side in an axial direction of the ink fountain roller;
• one select roller onto which only one ink among the inks of the plurality of colors fed from the ink fountain roller is selectively transferred;
• one oscillating roller which is provided for the one select roller and supported in such a manner as to be movable in an axial direction of the one oscillating roller, and onto which the one ink fed from the one select roller is transferred;
• one form roller provided for the one oscillating roller, including one convex portion on an outer peripheral surface thereof, and configured to rotate in such a manner that the one convex portion comes into contact with the numbering unit, the one convex portion being a portion onto which the one ink fed from the one oscillating roller is transferred;
• another select roller onto which, among the inks of the plurality of colors fed from the ink fountain roller, only another ink of a color different from the color of the ink transferred onto the one select roller is transferred;
• another oscillating roller which is provided for the another select roller and supported in such a manner as to be movable in an axial direction of the another oscillating roller, and onto which the another ink fed from the another select roller is transferred;
• and
• another form roller provided for the another oscillating roller, including another convex portion on an outer peripheral surface thereof, and configured to rotate in such a manner that the another convex portion comes into contact with the numbering unit, the another convex portion being a portion onto which the another ink fed from the other oscillating roller is transferred.
