Embodiment Construction

[0033] figure 1 A disc changer 1 according to the invention is shown in . In this embodiment, the disc changer 1 comprises a drawer 12 supporting five trays 2 for loading up to five optical recording media 24 . However, a different number of trays 2 can also be used. Each of the bottom four trays 2 consists of image 3 Guided by a pair of guide rails 6 shown in , while the uppermost tray 2 is guided by Figure 4 The top rail 10 shown in the guide. There are guide grooves 7 and other guide grooves 13 (such as Figure 5The guide rails 6, 10 shown in ) are used to guide the tray 2 from the storage position to the operating position. In the storage position, since the trays 2 are closely stacked, the user cannot access the optical recording medium 24 carried on the trays 2 . If the user wants to change one or more optical recording media 24, the disc changer 1 moves the drawer 12 together with the tray 2 from the storage position to the access position. For this purpose, th...
