Embodiment Construction

[0020] The tray 1 shown in Figures 1 to 4 is made of plastic and is substantially rectangular in top view (Figure 1) and bottom view (Figure 3). The tray is provided on its upper side with a circular recess 2 for receiving and carrying a CD or DVD having a diameter of 12 cm. The notch 2 extends to both sides of the tray 1 to form a space 3 so that a CD or DVD can be engaged by the operator's hand while being carried by the tray 1 .

[0021] The tray 1 is provided with a central opening 4 with a circular portion 5 for accommodating a turntable 6 when the CD or DVD is rotationally driven, and for accommodating an optical pickup unit 8 when the CD or DVD is being recorded or reproduced. The substantially rectangular portion 7 (see FIG. 5 ). The turntable is rotatable about an axis of rotation 6a and is provided with a support surface 6b.

[0022] The tray 1 is provided on its underside with a protruding piece 9 which is rectangular in bottom view (fig. 3) and has a flat sloping...

Abstract

An optical disc device comprising a tray (1) for carrying an optical disc, which tray (1) can move between a position inside the device and a position partly outside the device. The device also comprises a structure (13) for holding and driving the optical disc, which structure (13) is provided with a turntable (6) and an optical pickup unit (8) and guiding means for moving the optical pickup unit (8). The structure (13) can tilt around a horizontal tilt axis (14) behind the rotating optical disc. The tray (1) is provided with a catch member (9) and the optical pickup unit (8) is provided with a cooperating catch surface (20), whereby the catch member (9) may hit the catch surface (20) when the tray (1) moves, thereby displacing the optical pickup unit (8) into a save position.

Description

technical field [0001] The present invention relates to an optical disc recording and / or reproducing device comprising a tray for carrying an optical disc, the tray being movable between a rearward position inside the device and a forward position partially outside the device, to or from the device Inserting or removing an optical disc, this apparatus also includes a structure for holding and driving the optical disc during recording or reproducing operations, this structure is provided with a turntable, an optical pickup unit behind the turntable, and guide means for Moving the optical pick-up unit in a plane parallel to the rotating disc between a forward position near the turntable and a rearward position away from the turntable, such that the structure is capable of tilting about a horizontal tilt axis behind the rotating disc, the disc is at Between an up position in which the disc is drivingly clamped between the turntable and the clamper, a down position in which the st...
