Abstract:
1. A transportation apparatus for transporting a transportation target medium in a predetermined transportation direction, the transportation target medium transportation apparatus comprising: a transport driving roller that is operated rotationally; a transport driven roller that is urged against the transport driving roller and follows the rotary movement of the transport driving roller; and a control section that controls the movement of the transport driven roller between a contact position at which the transport driven roller is in contact with the transport driving roller and a non-contact position at which the transport driven roller is not in contact with the transport driving roller, wherein the control section moves the transport driven roller to the non-contact position at which the transport driven roller is not in contact with the transport driving roller when the thickness of the transportation target medium is at least a predetermined value, and then moves the transport driven roller to the contact position at which the transport driven roller is in contact with the transport driving roller when the length of time period in which the transport driven roller continues to be at the non-contact position exceeds a predetermined time period, and wherein the control section issues a message for notifying to a user that, in a case where the transport driven roller has been moved to the contact position at which the transport driven roller is in contact with the transport driving roller when the length of time period in which the transport driven roller continues to be at the non-contact position exceeds the predetermined time period, the moving of the transport driven roller to the contact position has been completed; and the control section causes the transport driven roller to stay at the contact position till the reception of the issued message by the user is confirmed.
