Image recording apparatus and control method for controlling image recording apparatus

An image recording apparatus which records an image on a sheet-shaped recording medium, the image recording apparatus comprising:

• a first placing section on which the recording medium is placed;
• a transport passage via which the recording media is transported and which has a curved portion;
• a first feed roller which feeds the recording medium placed on the first placing section to the transport passage;
• a first transport roller pair which is disposed at the curved portion and which interposes and transports the recording medium;
• a second transport roller pair which is located downstream of the first transport roller pair in a transport direction of the recording medium and which interposes and transports the recording medium;
• a recording head which discharges an ink onto the recording medium transported by the second transport roller pair;
• a first driving motor which is rotatable in forward and reverse directions;
• a first driving force transmitting section which transmits, to the first feed roller, a driving force of the first driving motor rotating in the forward direction and which transmits, to the first transport roller pair, a driving force of the first driving motor rotating in the reverse direction;
• a second driving motor which drives the second transport roller pair;
• and
• a controller which controls the first driving motor and the second driving motor, which controls the recording head to discharge the ink therefrom, and which selectively executes a first recording mode or a second recording mode,
• wherein the controller controls the first driving motor to transport the recording medium in the transport direction and to provide an interposed state in which the recording medium is interposed by both of the first and second transport roller pairs;
• in the first recording mode, the controller stops driving of the first transport roller pair for a predetermined period of time in the interposed state to transport the recording medium by the second transport roller pair, controls the second driving motor intermittently to drive and stop the second transport roller pair and controls the recording head to discharge the ink therefrom toward the recording medium during a stopping period in which the second transport roller pair is stopped;
• and
• in the second recording mode, the controller controls the first and second driving motors in synchronization in the interposed state to transport the recording medium by the first and second transport roller pairs, controls the first and second driving motors intermittently to drive and stop the first and second transport roller pairs and controls the recording head to discharge the ink therefrom toward the recording medium during a stopping period in which the first and second transport roller pairs are stopped.
