An anti-dust cover driving device for a CD player includes a base body, a laser head base unit mounted on the base body and having a laser head. An anti-dust cover is provided above the base body, moved to hide the laser head or not by a driving device consisting of a gear, a shaft, an activating means, and a power device for rotating the gear and the shaft. The anti-dust cover does not hide the laser head when a CD player cover is closed, but is moved to hide the laser head when the CD player cover is opened by means of the driving device. Therefore, the laser head is always hidden and prevented from having dust fall on it whether the CD player is closed or opened. And the anti-dust cover is moved within a short distance, not moving out of the dimensions of the CD player.
