PURPOSE:To accurately perform the positioning of an optical head by enclosing a drive motor for a card driving means and an optical head driving means with a vibrationproof metal and a vibrationproof rubber and lowering the vibration of the drive source. CONSTITUTION:The drive motor 20 is enclosed around by a plate made of the vibrationproof metal 21 and moreover enclosed all around again by the vibrationproof rubber 22, and then introducibly fixed into a case made of the vibrationproof metal 23, where supporting legs made of the vibrationproof metal for height adjustment 24 are fixed underneath the case 23. Consequently, the vibration of a high frequency component is absorbed by the plate 21, the case 23 and the supporting legs 24, all of which are made of the vibrationproof metal, while the vibration of a low frequency component is absorbed by the vibrationproof rubber 22. By this method, the head positioning can accurately be performed.
