Figures 1 to 3 show an embodiment of the present invention, with Figure 1 being a perspective view of the cam plate, and Figure 2 being a partial view of the optical disc fixed on the turntable. The cutaway side view, FIG. 3, is an explanatory diagram showing the distribution of the attraction force of the hub and the force applied to the pin. Figures 4 to 6 show conventional examples, with Figure 4 being an exploded perspective view showing the eject mechanism of the optical disc device, and Figure 5 showing the state in which the optical disc is fixed on the turntable. The partially cutaway side view shown in FIG. 6 is an explanatory diagram showing the distribution of the attraction force of the hub and the force applied to the pin. 1... Disc holder, 3...
