1. Field of the Invention
The present invention generally relates to a portable disc player.
2. Description of Related Art
A commonly used portable disc player, such as a portable digital versatile disc (DVD) player, is normally a lid-type. A lid-type disc player includes generally a main body and a lid pivotally connected to the main body via a hinge assembly. The main body includes a receiving portion for receiving a disc, a spindle motor for rotating the disc, and a pickup head for reading information from, or writing information to, the disc. The lid is configured for protecting the pickup head and the disc when the disc is being rotated by the spindle motor.
However, under certain conditions, the lid may be used occasionally to support foreign objects, such as books, fruits, when the disc is being played by the disc player. When this happens, the lid may be deformed such that the under surface of the lid will be scratching the rotating disc. In addition, a friction is generated between the lower side of the lid and the disc, which resists the rotating of the disc and even damages the disc.
Therefore, an improved portable disc player is needed in the industry to address the aforementioned deficiency.
A portable disc player includes a main body and a lid pivotally connected to the main body. The main body includes a cover, a base, and a traverse module. The traverse module is configured for reading information from, or writing information to, a disc. The cover and the base cooperatively fix the traverse module therebetween. The cover defines an opening for exposing the disc rotator. The traverse module includes a disc rotator for supporting and rotating the disc. A protrusion forms on a lower side of the lid corresponding to the disc rotator.
Other advantages and novel features will become more apparent from the following detailed description of preferred embodiment when taken in conjunction with the accompanying drawings.

The traverse module 93 includes a bracket 40, a disc rotator 50, and a pickup head 60. The bracket 40 is configured for supporting the disc rotator 50 and the pickup head 60. The bracket 40 defines a rectangular slot 42 for allowing the pickup head 60 to slide therein, and a circular opening 44 for exposing the disc rotator 50.
The disc rotator 50 includes a supporting part 52, a spindle motor 58, a turntable 54, and a damper 56. The supporting part 52 is fixed to the bracket 40, and is configured for supporting the spindle motor 58. The spindle motor 58 is connected to the supporting part 52 for rotating the turntable 54. The turntable 54 is connected to a rotor (not shown) of the spindle motor 58 and is configured for loading and rotating the disc 70. The damper 56 is fixed on the turntable 54 and capable of releasably clamping the disc 70 on the turntable 54 via three flexible clamping members 561.
The lid 30 includes a lower side 31. A protrusion 32 is formed in the lower side 31 of the lid 30 corresponding to the disc rotator 50. The base 10 includes an inner side 11. A supporting member 12 extends upwardly from the inner side 11 towards the disc rotator 50. For example, the supporting member 12 is a hollow cylinder. The protrusion 32, the disc rotator 50, and the supporting member 12 are disposed correspondingly with their centers being at an imaginary line (not shown). A diameter of the protrusion 32 is smaller than that of the damper 56.
