Top view (Regarding the regeneration mechanism part, Fig. 2 shows the mechanism operated by one cam surface of the cam gear, and Fig. 3 shows the mechanism operated by the other cam surface of the cam gear), Fig. 4
Figures 6 and 5 mainly show the configuration of the playback mechanism as viewed from the direction of arrow E in Figure 1.Figure 6' is a view seen from above the playback mechanism, and Figures 7A and C are views showing the structure of the playback mechanism as seen from above. Figures showing the shape of the cam grooves on each side of the cam gear, Figure 7B is the same as Figures A and C.
A cross-sectional view taken along line B-■B, Figure 8 A shows the disc carrying arm, B shows the positioning plate, C shows the guide plate, the same shows the disc player, E shows the disc clamper, the same shows F is a diagram showing the operation of the disk separator in response to the rotation angle of the cam gear, and FIGS. 9A to 9E and 10A to 10E are diagrams showing changes in the operating state of the device according to the rotation of the cam gear, respectively. FIG. 11 is a diagram schematically showing the configuration corresponding to the rotation angle of the cam gear, and FIG.
2 and 13 are enlarged longitudinal cross-sectional views showing the state of the disk reproducing portion before and after operation, respectively, and FIG. 14 is a perspective view showing the clamp arm and clamper. 1... Compact disc automatic selection playback device, 2...
