The present invention relates to a disc guiding mechanism, having: a main body which provided with a teeth array at one side; a first sliding bar and a second sliding bar both of which are provided on the main body; a transmission element provided on the main body and engaged with both of the sliding bars; a first hook and a second hook rotatably provided on each sliding bar respectively; and a first elastic member and a second elastic member provided on each sliding bar to provide an elasticity on the hooks. According to the disc guiding mechanism of the present invention, a disc is guided by the hooks and carried into an optical disc device, the transmission element restricts the first and the second sliding bars to slide symmetrically, so that the disc is guided and carried in a correct direction. Accordingly, a disc jamming in the optical disc device resulted from loading in an incorrect direction is avoided.
