Abstract
A printer includes an apparatus body having a recording head for performing recording onto a sheet of paper. The printer also includes a unit body that is accommodated inside the apparatus body and has a path-forming surface formed at least on a portion of the periphery of the unit body. The path-forming surface forms a medium transport path. The unit body includes a plurality of openings that are in communication with a sound absorber disposed inside the unit body. The plurality of the openings are provided at least on a portion of the path-forming surface.
