An image reading apparatus comprising:

• a housing having a conveying path extending in a conveying direction;
• a recording head;
• a first transport roller pair located downstream of the recording head in the conveying direction and including a first driving roller and a first driven roller;
• a second transport roller pair located downstream of the first transport roller pair in the conveying direction and including a second driving roller and a second driven roller;
• a reading unit located between the first transport roller pair and the second transport roller pair in the conveying direction;
• a sheet support portion facing the reading unit;
• a glass plate located between the reading unit and the sheet support portion;
• and
• a rotating body located at a first position or a second position, the first position being between the first transport roller pair and the reading unit, the second position being between the reading unit and the second transport roller pair in the conveying direction;
• a first support member that supports the reading unit and the rotating body;
• a second support member that supports the first driven roller and the second driven roller,
• wherein the reading unit further comprises:
• a light source for irradiating the sheet support portion with light through the glass plate;
• and
• a light receiver for receiving light through the glass plate;
• wherein the rotating body has a plurality of projections projecting radially outwardly, and
• wherein a distal end of one of the plurality of projections is positioned closer to the sheet support portion than the glass plate.
