ABSTRACT:
A disc loading apparatus for a disc player based on the front loading method is disclosed. Positioning ribs formed on the tray supporting steps of a tray holder are meshed during operation with rib guiding grooves which are formed on the bottom of a tray. Upper and lower carrying rollers which are closely contacted with a guide band, or a carrying gear which is closely contacted with a rack gear revolve in such a manner that the tray would enter into a tray holder stably and precisely, thereby making the tray run fast. Set rollers which are formed on the inside of the tray holder prevent the lifting of the tray, so that the tray would move more stably. Further, the upper and lower carrying rollers which are clad with rubber make the movement of the tray more precise, as well as preventing the generation of noise in the meshing portions.
