Abstract: The present invention provides a transmission mechanism for disk player driving systems, mainly improves the disadvantages of the currently available technology, such as complicated structure and high production cost. The present invention includes a slot for inserting recording media, the slot is flanked by a chassis, a plurality of wall troughs with downward curves at the back end are formed on each side of the chassis, a transfer base installed inside the slot with a plurality of guide bars extend and intersect the chassis, the guide bars guide the inserted recording medium onto the required position for reading.

Abstract: A slot-in loading system that is compatible for various disc sizes comprises a housing unit, a transfer base, a disc driving apparatus and a signal switch means. A slot for inserting disc and a transfer base are provided inside of the housing unit. The transfer base includes a disc compatible apparatus, which is connected to the transfer base flexibly, and the fore end of the disc compatible apparatus is free to turn within certain angles. A disc allocation apparatus is also provided at the fore end. The slot-in loading system has many advantages, such as no disc tray required, simple structure, very thin, low noise, low cost, compatible with various disc sizes, high reading and writing quality, effectively clamping disc with little or no damage and distortion to disc and the laser head and collimating lens apparatus can effectively avoid vibration and keep an accurate relative position to the disc.
