Abstract
In a disc playback device of a type in which a disc or a disc cartridge case housing a disc is loaded in a holder and the disc is played back upon moving of this holder from a disc loading position to a disc playback position, magnetic attraction generating means is provided for attracting the holder and a chassis carrying a turntable to each other. The magnetic attraction generating means may be constructed by securing a magnet to either the chassis or the holder and forming the other with magnetic substance, or may be constructed by securing magnets to both the chassis and the holder. The holder is securely clamped in position when it has been moved to the disc playback position and anti-vibration characteristics of the holder are thereby improved.
