Patent ID: 8177444

Claim:
A printer comprising: a bi-directional motor structured to rotate in opposing first and second directions; a print head; a drive shaft coupled to the bi-directional motor; a first one-way clutch mounted to the drive shaft; a drive roller coupled to the first one-way clutch, wherein the drive roller advances a web toward the print head upon rotation of the bi-directional motor in the first direction; a second one-way clutch mounted to the drive shaft; a cutter coupled to the second one-way clutch for cutting the web upon rotation of the bi-directional motor in the second direction; an ejection roller coupled to the second one-way clutch, wherein the ejection roller defines a rotational axis and a cross sectional shape having a non-uniform radius as measured from the rotational axis, wherein the non-uniform cross sectional shape of the ejection roller defines a maximum radius as measured from the rotational axis, and wherein the ejection roller ejects the web at least partially from the printer in conjunction with the web being cut by the cutter when the drive shaft is rotated in the second direction by the bi-directional motor; and a door having a closed position and an open position, wherein the door is biased in the closed position and disposed proximate the ejection roller, and wherein the door is forced into the open position by the ejection roller when the door is contacted by an area of the ejection roller disposed generally proximate the maximum radius of the ejection roller.
