[0130] Next, use Figure 12 , Figure 13 An optical disc device D according to the second embodiment will be described.
[0131] in addition, Figure 12 (a) is a plan view of the decorative plate 10 of the optical disc device D according to the second embodiment, Figure 12 (b) yes Figure 12 (a) is an enlarged cross-sectional view along line D-D of the decorative panel 10 with the disk tray 3 added thereto.
[0132] In the first embodiment, the air guide wall 22 is formed in the disk tray 3, but in the optical disc device D2 of the second embodiment, the above-mentioned air guide wall 22 is provided in the decorative panel 10 and is used as the air guide. wall 10b.
[0133] The configuration other than that is the same as that of the first embodiment, so the same components are given the same reference numerals and detailed descriptions thereof are omitted.
[0134] Such as Figure 12 As shown in (a), in the optical disc device D2 of the second embodiment, when the opt...
no. 3 approach
[0147] Next, use Figure 15 A third embodiment will be described. in addition, Figure 15 is the third embodiment Figure 4 (a) Enlarged view of the C-C line section.
[0148] The third embodiment is a structure in which air guide walls continuous with the air guide holes 21 of the decorative plate 10 are respectively provided on both the disk tray 3 and the decorative plate 10 .
[0149] In a third embodiment, with Figure 4 (a) Similarly, when the optical pickup unit 7 moves to the outermost peripheral position of the mounted disc 2, in the decorative plate 10, the region substantially facing the laser element 8a of the optical pickup unit 7 and its vicinity, An air guide hole 21 is provided through it.
[0150] In addition, in the rear surface 3a of the disc tray 3, the laser element 8a of the optical pickup unit 7 at the outermost peripheral portion of the moved disc 2 (refer to figure 1 (a)) In the opposite back side 3a and the decorative panel 10, respectively as ...
