    Abstract: For providing a recording medium playback apparatus, which can prevent that clamping a recording medium in playback is unlocked, a CD changer includes a movable frame 66, a clamp unit 67, a pick-up unit 69, a lock unit 70 and a clamp lock/unlock unit 71. The movable frame 66 is movable against a main body. The clamp unit 67 is arranged on the movable frame 66 and clamps a CD 2. The pick-up unit 69 can move freely between a unclamp position to move close to the clamp unit 67 so as to unlock clamping of the clamp unit 67 and a playback position apart from the unclamp position more than the clamp unit 67. The lock unit 70 can move freely between a unlock position to make the movable frame 66 movable and a lock position to fix the movable frame 66. The clamp lock/unlock unit 71 in the unlock position limits the pick-up unit 69 to move close to the clamp unit 67 until the unclamp position.
