Embodiment approach 1
[0029] First, the structure and operation of a DVD player device (hereinafter referred to as an optical disc device) incorporating the disc clamping mechanism according to Embodiment 1 of the present invention will be described.
[0030] 1 and 2 are perspective views of the optical disc device 1 according to Embodiment 1 viewed obliquely from above. 1 shows a state where the disc tray 12 of the optical disc device 1 is in a protruding position, and FIG. 2 shows a state where the disc tray 12 of the optical disc device 1 is housed.
[0031] As shown in FIG. 1 , the optical disc device 1 includes: a main frame 11 ; an optical disc tray 12 provided on the main frame 11 so as to be freely accommodated and ejected;
[0032] Here, for the convenience of description, as shown in FIG. 1 , on the same plane as the disc tray 12 (that is, the same plane as the disc surface on the disc tray 12), the direction parallel to the storage and discharge direction of the disc tray 12 will be The...
Embodiment approach 2
[0068] Figure 10 It is a front view of the side portion of the disc clamper pressing member 14 of the disc clamping device 1 according to Embodiment 2 viewed from the +Y side. In the first embodiment described above, although the height (dimension in the Z direction) of the disc holder pressing member 14 is constant (see FIGS. 2 and 3 ), in the second embodiment, the height of the disc holder pressing member 14 is constant. The height gradually decreases from the central portion to the end portion 14b.
[0069] More specifically, the height (dimension in the Z direction) of the disc holder pressing member 14 gradually decreases from the central portion of the disc holder pressing member 14 to the end portion 14b in the −X direction. On the other hand, the height of the disc holder pressing member 14 is constant from the center portion of the disc holder holding member 14 to the end portion 14a in the +X direction (the portion mounted as a swing fulcrum on the main chassis 11...
Embodiment approach 3
[0074] Figure 11 (A) to (C) are cross-sectional shapes ( Figure 11 (A)) A cross-sectional view showing the cross-sectional shape of the disc holder holding member of the present embodiment for comparison. Figure 11 (A) ~ (C) are equivalent to Image 6 The sectional view at plane XI shown (YZ sectional view).
[0075] In the above Embodiment 1, as Figure 11 As shown in (A), although by making the disc holder pressing member 14 have The cross-section ensures strength, but even other cross-sectional shapes can ensure strength. E.g, Figure 11 The disc holder pressing member 14 shown in (B) has a U-shaped cross-section instead of Glyph section. In this case, the disc holder holding member 114 has a pair of side plate portions 114a, 114b facing in the Y direction and a bottom plate portion 114c curved in the -Z direction within the YZ plane. In addition, a W-shaped cross section may be used instead of a U-shaped cross section. Even with such a cross-sectional shape, ...
