PURPOSE:To prevent noise due to mechanical vibration from being introduced to a reproduced output, by coupling the 2nd base to the 1st base supporting the reproducing system such as a linear tracking arm via a bushing made of a viscoelastic substance. CONSTITUTION:The motor and the drive side of a gear reducer mechanism are supported with the separate 2nd base 14, and the 1st base 13 supporting the reproduction system such as a slide shaft 5 supporting the linear tracking arm 3 slidably and a guide plate 11 is coupled with a bushing 15 made of a viscoelastic substance such as rubber. In the figure, 16 is a fixing screw. The vibration of the driving side of the motor is attenuated and absorbed with the bushing 15 made of the viscoelastic substance and not delivered to the 1st base plate 13. Thus, the linear tracking arm 3 is prevented from invasion of the mechanical vibration, and introduction of noise to the reproducing sound is prevented. |
