Apparatus for driving a ribbon of a printer

Abstract

An apparatus for driving a ribbon of a printer allows a ribbon driving shaft to move the forward/back and right/left directions for being moved together with a ribbon cartridge when the ribbon cartridge is moved by centering about a hub, thereby smoothly transmitting a rotating force toward the hub. For this operation, the apparatus includes the ribbon cartridge winding with a ribbon to be coupled with the ribbon driving shaft, and a driving bevel gear and a driven bevel gear installed to the inside of a printer main body for rotating the ribbon driving shaft, in which a ratchet rotating in one direction is formed to a lower portion of the ribbon driving shaft, a ratchet wheel brought into meshing engagement with the ratchet is formed along the inner periphery of the driven bevel gear, and movement guiding means is installed to a bottom plate forming the printer main body for guiding to be capable of moving together with the rotation of the ribbon driving shaft.
