The present invention is to provide a playback apparatus for assuredly guiding a disk shape recording medium to a holder. A CD changer 1 has a main body 3, a holder 19, and a guiding mechanism 91. The main body 3 has a slot 10 for inserting or removing a CD 2. The holder 19 has a holder body 80 and a locking member 82. The holder body 80 has a C-shaped retainer 84 and a flange 85. The locking member 82 is disposed at an end 80b of the holder body 80 and locked to the CD 2. The guiding mechanism 91 has an arm main body 92 and a guiding part 94. The arm main body 92 is disposed rotatably. The guiding part 94 projects inwardly from an inner edge 85a of the flange 85 when the CD 2 is inserted. The guiding part 94 has a pair of guiding projections 96. The guiding projections 96 position an outer edge of the CD and the locking member therebetween. The guiding projections 96, or the guiding mechanism 91, guide the CD to the holder 19.
