Abstract:
An ink supplier of a printer having a printing drum, comprising:a frame including a pair of mutually opposing side plates;an ink supply roller supported by the frame between the pair of side plates to rotate about a central axis thereof, an outer circumferential surface of the ink supply roller slidably contacting an inner circumferential surface of the printing drum of the printer;an ink supply control member supported by the frame between the pair of side plates and extending along a generatrix of the ink supply roller, thereby defining an ink holding space converging to an ink metering clearance with the outer circumferential surface of the ink supply roller;an ink driving rod member disposed in the ink holding space and extending along a generartrix of the ink supply roller, the ink driving rod member rotating around a central axis thereof in synchronization with a rotation of the ink supply roller, the ink driving rod member rotating in a direction opposite to a direction of rotation of the ink supply roller; andan ink interrupting member disposed between the pair of side plates and extending along a generatrix of the ink supply roller proximate to the outer circumferential surface of the ink supply roller, the ink interrupting member being opposite to and parallel with the ink supply control member relative to the ink holding space and being substantially the same length as that of said ink supply roller, the ink interrupting member contacting a circumferential part of a lump of ink formed in the ink holding space, thereby restricting a lateral extension of a cross section of the lump of ink.
