Abstract
A disc changer has a protector which protects the operation of the disc changer even when an oscillation is applied to the disc changer, without adding a new oscillation sensor to the disc changer. In the disc changer that takes out a desired disc from a stocker with a swing arm and returns the reproduced disc to the stocker, an oscillation sensor monitors an output of a position sensor which detects a position of a member that rises and falls within the disc changer. Based on a variation in the output of the position sensor, the oscillation sensor detects a size of the oscillation applied to the disc changer. When the oscillation is larger than a predetermined value, the swing arm operation of clamping a disc and returning a disc to the stocker is temporarily stopped or is restarted, thereby protecting the disc changer from the oscillation.
