Patent ID: 8777397

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 first position and a second 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 approaches 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; an elastic shaft configured to support the spur roller and urge the spur roller toward the drive roller; 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, and 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 a second contacting portion protruding from the rotating shaft in the radial direction and configured to deform the elastic shaft and to move the spur roller to the fifth position when the rotating shaft rotates from the first position to the second position.
