Patent ID: 8646905

Claim:
A conveyor device comprising: a drive roller configured to selectively convey one of a tray and a sheet through a conveying path; a rotating shaft extending in a direction parallel to an axial direction of the drive roller and configured to selectively rotate between a third position and a second position via a first position; a spur roller disposed opposite from the drive roller across the conveying path and configured to move between a fourth position, in which the spur roller contacts the drive roller, and a fifth position, in which the spur roller separates from the drive roller at a distance greater than a thickness of the tray; a first contacting portion protruding from the rotating shaft in a radial direction of the rotating shaft, wherein the first contacting portion is disposed in the conveying path when the rotating shaft is in the first position, the first contacting portion is configured to contact one surface of the tray passing through the conveying path when the rotating shaft is in the second position, and the first contacting portion is separated from the conveying path when the rotating shaft is in the third position; a second contacting portion protruding from the rotating shaft in the radial direction and configured to move the spur roller, such that, when the rotating shaft is in the first position, the spur roller is in the fourth position, and when the rotating shaft is in the second position, the spur roller is in the fifth position; and a rotating unit configured to rotate the rotating shaft from the third position to the first position.
