A media transportation mechanism and a media processing device enabling carrying media without transportation errors or picking errors by accurately detecting if media is present. A media transportation mechanism 31 has a gripping mechanism 130 for holding media and a media detection mechanism 200 for detecting media gripped by the gripping mechanism 130 positioned on a transportation arm 36 that can move up and down. The media detection mechanism 200 has a detection lever 201 that is pivotably supported on the arm base 125 a of the transportation arm 36 and is displaced from a media-not-detected position in contact with the arm base 125 a to a media-detected position separated from the arm base 125 a when the detection lever 201 contacts the media, a detector 202 that detects displacement of the detection lever 201 to the media-detected position, and an attraction unit including a magnet 203 and steel plate 204 that pull the arm base 125 a and detection lever 201 together using magnetic force.
