CHUCKING DEVICE FOR A DISK

摘要

PURPOSE: A disk chucking apparatus is provided to secure driving performance of the optical disk by increasing a detachment force of an optical disk. CONSTITUTION: A disk chucking device includes a turn-table(110), a housing(120), a chuck pin(130), a spring(140), and a spring combination unit. An optical disk is received on turn-table. The housing is formed on the turn-table and is inserted into a center hole of the optical disk. One side of the chuck pin is protruded to the outside of the housing and is contracted to the central direction of the optical disk by inserting or separating the optical disk. The spring is installed inside the housing and elastically supports the other side of the chuck pin to the opposite direction to the central direction. The spring combination unit is formed on the chuck pin to be closely adhered to the spring and is incline to apply the elastic force of the spring to the turn-table.
