Claims

[Scope of Claim for Utility Model Registration] A jacket that stores a recording disc through an opening and a lid plate having a notch at the front end of the jacket is inserted into the jacket insertion slot of the main body of the playback device. During playback, a tracking device disposed within the main body of the playback device so as to be able to move forward and backward checks the recording disc and the lid plate from within the jacket, and automatically pulls the disc out into the main body of the playback device and places the recording disc on the turntable. However, after the reproduction is finished, by inserting an empty jacket into the jacket insertion slot, the chucking device operates to store the recording disk together with the lid plate into the jacket again,
In the lid plate detection device of the recording disc playback device configured to detect the notch in the lid plate and display the contents of the recording disc, the lid plate detection device is provided in the chucking device and is configured to detect a notch in the lid plate depending on whether or not there is a notch in the lid plate. an actuating body that assumes a first and a second position; and an actuating body that is provided near a jacket insertion port in the main body of the playback device, and when the chucking device moves forward and chucks the recording disk and lid plate, the actuating body 1. A lid plate notch detection device for a recording disc playback device, comprising a notch detection switch that is turned on and off.
