Embodiment Construction

[0024] The following reference Figures 1 to 7 A floating chassis support mechanism for a vehicle-mounted CD player according to an embodiment of the present invention will be described. figure 1 and 2 A disc motor 7, an optical head 9, and an optical head transport mechanism are supported on the floating chassis 3 shown in . During disc playback, Figures 10B to 10D The main chassis 10 shown in FIG. 5 supports the floating chassis in a floating state through shock absorbers 4, 4, 4 and coil springs 5 ​​shown in FIGS. During disc playback, all shock absorbers 4, 4, 4 are outside the projection area of ​​the disc.

[0025] When loading / unloading the disc 15, the locking mechanism ( Figures 10B to 10D 25, 21a) shown in 25, 21a) lock the floating chassis 3 on the main chassis, the optical disk 15 is pressed between the optical disk guide 1 and the optical disk delivery roller 2, and the optical disk 15 is in the playback position when the optical disk delivery roller 2 rota...

Abstract

The invention relates to a vehicle mount disc reproduction apparatus having a reproduction unit chassis supported during reproduction in a floating state by a main chassis with springs and dampers, the dampers being disposed outside of an area of a projection of a disc, and an area of the floating chassis supported with the dampers being set higher than the other area of the floating chassis, wherein when the disc is loaded or unloaded, the reproduction unit chassis is locked to the main chassis in a state shifted toward a disc insert port.

Description

technical field [0001] The present invention relates to an optical disc device such as a CD player, and more particularly, the present invention relates to a floating chassis support mechanism suitable for a vehicle-mounted optical disc device. [0002] The present invention also relates to a vehicle-mounted optical disk playback device in which the playback unit chassis is supported in a floating state by a main chassis having springs and shock absorbers, and more particularly, relates to the movement of the playback unit chassis when the optical disk is taken out and put in. Lock position. Background technique [0003] refer to Figures 11 to 13 An example of the structure of an existing floating chassis support mechanism for a vehicle-mounted CD player is described. Figure 11 and 12 A disc motor 7, an optical head 9, and an optical head transport mechanism are supported on the floating chassis 11 shown in . During disc playback, the main chassis (not shown) supports t...
