  • Publication number: 20200223234
    Abstract: A recording apparatus is provided with a transport roller pair which transports a medium toward a recorder, a feed roller which transports the medium toward the transport roller pair, and a controller which controls the transport roller pair and the feed roller. The controller is capable of executing a combined skew rectification mode which executes one of a first skew rectification operation in which a leading end of the medium abuts the transport roller pair using backward rotation of the transport roller pair and forward rotation of the feed roller and a second skew rectification operation in which the transport roller pair to rotate backward without driving the feed roller and discharges the leading end of the medium to the upstream side of the transport roller pair, and subsequently executes the other of the skew rectification operations.

  • Patent number: 8356810
    Abstract: A transport device includes a stopper which comes into contact with a target ahead of a guide surface of a guide member and regulates movement of the target and a slider which slides by contact of the target with the stopper. The stopper has a first regulation surface with which the target comes into contact ahead of the guide surface of the guide member, and a second regulation surface which regulates the movement of the target which moves along the first regulation surface. A damper mechanism is connected to the slider and has a damper force that weakens kinetic energy by the target that the stopper receives.
