Patent ID: 7343609

Claim:
A control mechanism for a clamper guider in a slot-in drive, comprising a control sheet connected at the upper side of a ceiling plate on a chassis; an arm being extended from the side of said control sheet and three guide slots being symmetrically disposed at a same circumference; a guide pin is combined with said arm and said guide pin being passed through a guide slot in a transmission; said transmission sheet being movable on the upper side of said ceiling plate; three guide pins being connected at a location at the upper side of said ceiling plate relative to said three guide slots in said control sheet and said guide pins being passed through and out of said guide slots to combine each with a C-ring; a clamper being combined with a lower section extended downward from the front end of a clamper guider and the rear end of said clamper guider being connected pivotally to said ceiling plate; a spring for providing said clamper with a downward suppressing force being installed between said clamper guider and said ceiling plate; a hole section is respectively disposed in locations of said ceiling plate and said control sheet relative to said clamper, the hole section extends in a concentric circle and is located in between the control sheet and the clamper; a raised piece projected upward and relative to the side of said clamper guider being installed on said control sheet and a slant face being formed at one side of said raised piece facing to said clamper guider; a motor and transmission gear train being combined with said chassis; whereby, said transmission is driven to move by said motor through said transmission gear train and said control sheet being driven by said transmission to take said three guide pins as supporting point to be rotated counterclockwise or clockwise so as to allow said raised piece of said control sheet to slide against or separate from the lower end of said clamper guider to control said clamper to separate from or enter the location that a disc is clamped.
