Abstract: A visualized indicator is applied to a slot-in optical reproducing apparatus. By providing a display window on the housing of the apparatus and a visualized indicator inside the housing, a first portion or a second portion of the visualized indicator can be alternatively shown through the display window to tell if a disk is inside the apparatus or not.

Abstract: A mechanism for facilitating alignment of a tray in an optical disc drive includes a first engaging member, a second engaging member and a flexible member. The tray is hidden in a slot of the optical disc drive with the covering of a tray door and coupled to the tray door via a tray mount. The first engaging member is arranged at a side wall of the slot. The second engaging member is arranged at a side wall of the tray door for engaging with the first engaging member when the tray is received in the slot. The flexible member is arranged at a side of the tray mount opposite to the tray door. The flexible member is deformed when the tray is retracted into the slot, and restores to urge the tray mount against the tray door when the tray is ejected from the slot.
