Abstract: This invention relates to a sticking roller for sticking a label on an information recording board having a nearly doughnut shape in a plan view. The roller comprises a roller body and an elastic member fitted on the outer circumference of the roller body. The roller body has a fitting part for fitting the elastic member on the outer circumference of the roller body, and the fitting part has stepped portions along the inner and outer circumferential edges of the elastic member. The stepped portions regulate a deformation or shift of the elastic member in its surface direction when applying a sticking force on the label via the surface of the elastic member.

Abstract: An inking apparatus according to the present invention includes an ink fountain roller, an ink fountain blade, a front end of which is position-adjustable to be located close to the outer circumference of the ink fountain roller, a pair of side plates, each standing upright from the ink fountain blade so that an arcuate front end surface encircles part of the outer circumference of the ink fountain roller to form an ink fountain for storing ink in cooperative with the ink fountain roller and the ink fountain blade, in which a permanent magnet is embedded in a bottom surface of each the side plate in contact with the ink fountain blade for fixing the side plate to a desired position of the ink fountain blade. The pair of side plates are movable relative to the ink fountain blade along an axis of the ink fountain roller.

Abstract: A printing device of the type for printing a strip-like printing article having a printing impression roller which is movable forwards while rotating in one direction and backwards while rotating in the opposite direction, along a line perpendicular to the direction of feeding a strip-like printing article is provided with a slide base which is slidable along rails which extend in a direction perpendicular to the direction of feeding of the printing article. Ink tanks and a roller train are mounted on the slide base. The roller train includes an ink fountain roller, a duct roller whose peripheral surface is in contact with the ink fountain roller, a stationary metallic roller whose peripheral surface is in contact with the duct roller, a first ink distribution roller whose peripheral surface is in contact with the metallic roller, and a second ink distribution roller whose peripheral surface is in contact with the first ink distribution roller.
