The present invention is to provide a media processing apparatus for enabling a plurality of discharge sections disposed one side of the apparatus to be disposed parallel inside saved space, the media processing apparatus is provided with a plurality of discharge sections (correct card discharge section and error card discharge section) disposed on one side of an apparatus housing, and a discharge member (card reverse section) that discharges a card C to each discharge section. In such a card processing apparatus, a width dimension (length dimension in the discharge direction of the card) of a discharge stacker of the first card discharge section is wider than a width dimension of the card C, and a width dimension of a frame body of the error card discharge section is narrower than the width dimension of the card C.
