A main body has a receiving section, which contains an ink ribbon cassette holding an ink ribbon, together with an optical disk. The ink ribbon and the optical disk are fed by a platen roller, and printing is performed on the optical disk through a thermal head. The optical disk is inserted from an insertion port at a side of the main body parallel to the feed direction of the ink ribbon. When the optical disk is inserted from an ejection port in a direction orthogonal to the fed direction of the ink ribbon, an insertion-prevention member prevents the insertion of the optical disk.
