A vehicle mount disc player having a small thickness by removing a wasteful space around a reproduction unit chassis when a disc is loaded or unloaded. The vehicle mount disc player has the reproduction unit chassis supported in a floating state by a main chassis via damper mechanisms. The reproduction unit chassis is locked so as to be shifted to a disc motor side along an axial direction of a disc motor and a turntable when the disc is loaded or unloaded.

Disc player mounted on vehicle

A disc reproduction apparatus capable of stabilizing the position of the circumferential edge of a disc during the disc loading and preventing the disc from abutting on a turntable. In the disc reproduction apparatus of the type that a disc squeezed between a disc guide and a disc roller is loaded while the roller is rotated, a disc contact surface of the disc guide is slanted so that the disc is spaced from a turntable along a disc transport direction when the disc is loaded.

Disc loading mechanism of disc apparatus

A floating chassis support mechanism is provided which can thin a disc reproduction apparatus. In the floating chassis support mechanism for a disc reproduction apparatus for supporting a floating chassis with springs and dampers vertically from the opposite side of a loaded disc, the damper is disposed outside of a projection area of the disc, and an area of the floating chassis supported by the dampers is retracted towards the disc side more than a lower surface of the disc.

Supporting structure with locking mechanism of floating chassis of disc apparatus

A contact between a clamper holder and clamper and between the clamper holder and disc can be reliably prevented while the disc is rotated. A disc clamp mechanism for a disc apparatus for clamping or unclamping a disc by moving a clamper holding chassis near to or remote from a turntable, the clamper holding chassis holding a clamper with a clamper holder, wherein: a lever is rotatively supported by the clamper holding chassis and moved in cooperation with a motion of the clamper holding chassis; and a contact portion of the clamper holder with the clamper is displaced in a motion direction of the clamper holding chassis and a clamper radial direction relative to the clamper holding chassis, in cooperation with a motion of the lever relative to the clamper holding chassis.

Disc clamp mechanism for disc apparatus

A disc clamp mechanism for a disc apparatus is provided. In the disc clamp mechanism, a disc is clamped or unclamped by moving a clamper holding chassis near to or remote from a turntable, the clamper holding chassis holding a clamper with a clamper holder, and a contact portion of the clamper holder with the clamper is deformed relative to the clamper holding chassis along a motion direction of the clamper holding chassis. A large space can be formed between the clamper and a turntable in a disc unclamp state to prevent the disc from becoming in contact with the clamper or turntable and being damaged while the disc is transported. A stroke of the clamper holding chassis necessary for reserving the space is made small to make a disc apparatus compact.
