The present invention relates to a sensor mechanism of an optical disc device for detecting tray in/out motion, which comprises a swing bar having a actuating bar, a spinning center and a protrusion portion; a gear for driving the protrusion portion to rotate the swing bar against the spinning center; at least one sensor for emitting a signal that the tray has been already moved in/out when it is touched by the actuating bar, so that the device prepares to perform next function.

Sensor mechanism for detecting tray in/out motion

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.

Disc guiding mechanism

A disk reading device operates in both a suction mode and a cover-lifting mode. The device has a lower cover having a wall with an elongated opening provided in the wall, an upper cover that is connected for pivoting movement with respect to the lower cover, and a disk receiving space between the lower and upper covers. The disk receiving space is accessible via the elongated opening in a suction mode and by opening the upper cover with respect to the lower cover in a cover-lifting mode. A disk is drawn via the elongated opening into the disk receiving space, or a disk can be manually placed in the disk receiving space by opening the upper cover with respect to the lower cover. The device also includes a switch that switches operation of the disk reading device from the suction mode to the cover-lifting mode.
