Printing device especially for labelling appliances

Abstract

In a printing device such as labelling appliance having a printing table, a printer movably mounted with respect to the table, an ink carrier which inks printing types carried by the printer, an inking pivot member which holds the ink carrier at the free end thereof and which is pivotable against the force of a return spring, the pivot member being adapted to be pivoted out of the path of movement of the printer when the printer moves toward the printing table, the improvement comprising the ink carrier being a resilient transfer roller which is freely rotatably mounted with respect to the inking pivot member and including a dense, readily wettable surface, an inking roller that stores ink, the inking roller being made of a finely porous material, an inking roller support having side walls where each wall has an open-ended bearing recess which opens toward the transfer roller for freely rotatably supporting the inking roller about an axis parallel to the axis of rotation of the transfer roller, the inking roller support being pivotably supported by the inking pivot member about an axis which is parallel to the pivot axis of the inking pivot member, and a pressure spring for biasing the inking roller support so that the inking roller normally engages the transfer roller to ink the transfer roller upon relative rotation of the inking and transfer rollers, the inking roller being exchangeable by pivoting the inking roller support away from inking pivot member to thereby remove the inking roller out of contact with the transfer roller and thus permit the removal of the inking roller from the open-ended bearing recesses of the side walls of the inking roller support and the replacement thereof.
