Patent ID: 8479649

Claim:
An imprinter comprising: a printing base for mounting a card and a print paper to be imprinted on a predetermined area thereof; a carriage that is movable above the printing base; a roller shaft housed within the carriage and fixedly arranged at a position of a predetermined height from the card mounting surface of the printing base; and a roller including an outer periphery comprising a rigid body formed contiguously across an entirety of the roller in an axial direction of the roller, a center boss that is in rotational engagement with the roller shaft and an elastic member provided between the outer periphery and the center boss of the roller, wherein the elastic member is radially deformed during an imprinting operation so as to cause a radial center of the outer periphery of the roller to radially move relative to a center axis of the roller shaft into a state of eccentric circle in a vertical section, so that the embossed information of the card may be transcribed onto the print paper, and wherein a radially extending line from the roller shaft, in a state where the roller shaft is disposed in a center of the roller, passes through a straight portion of the elastic member directly adjacent to the outer periphery of the roller and a straight portion of the elastic member directly adjacent to the roller shaft.
