Abstract
The rotation of transmitting rollers can be transmitted to carrier rollers by making the transmission rollers contact with the carrier rollers paired in the front and rear direction by moving bearing member toward the upper side, whereas the rotation of the transmission rollers can be prevented from transmission to the carrier rollers by separating the transmission rollers from the carrier rollers by moving the bearing members to the lower side.
