摘要： A disc drive has an opening portion for inserting a disc. The disc drive includes a driving unit, a moving member, a traverse, a disc positioning structure and a restoring structure. When the disc is intended to be clamped on the traverse, the driving unit drives the moving member to move the traverse to a disc holding position to clamp the disc; and the moving member moves the disc positioning structure to a disc release position so that the disc positioning structure does not contact the disc. When the disc is intended to be released from the traverse, the driving unit drives the moving member to move the traverse to a disc unloading position to unload the disc; and the restoring structure moves the disc positioning structure to a disc loading position to support the disc.

摘要： A disc grabbing device including a support body, a drive shaft, multiple first planetary gears, a center gear, multiple second planetary gears and a driver is provided. The support body includes a plate and a center column. When the disc grabbing device grabs the discs, the center column is located in the center holes of the discs. The drive shaft is rotatably disposed on the plate. The first planetary gears are respectively engaged with the drive shaft and connected to multiple first levers for driving the first levers to rotate. The second planetary gears are respectively engaged with the center gear and connected to multiple second levers for driving the second levers to rotate. The driver concurrently drives the drive shaft and the center gear to rotate the first planetary gears and the second planetary gears synchronically and make the first levers and the second levers rotate synchronically.

摘要： A disc grabbing device including a body, a drive shaft, a first cam, a second cam, multiple first movable parts and multiple second movable parts are provided. The drive shaft is rotatably disposed in the body. A first cam and a second cam are disposed on the drive shaft, and rotate together with the drive shaft. The first movable parts are disposed in the body and correspond to the first cam, and move to a disc hold position or a disc release position along with the rotation of the first cam. The second movable parts are disposed in the body and correspond to the second cam, and move to a disc release position or a disc hold position along with the rotation of the second cam.
