摘要： In a color printer in which a drive force of a fixed gear that rotates not in both a forward direction and a reverse direction but in either one direction only is transmitted to a discharging unit, a swing gear is attached to a branch guide via a switching link and a transmission link as a link mechanism. When a solenoid mechanism starts driving, the transmission link rotates. In accordance with the rotation of the transmission link, the switching link rotates, so that a switching among a discharge conveying path, a duplex-printing conveying path, and a switchback conveying path by the branch guide and a switching of a rotating direction of a transmission gear can be simultaneously performed.
