Abstract

And a clutch means for switching the power so that the lifting means of the stocker member accommodating the plurality of sub-tray members and the clamping means for clamping the selected disk are selectively operated from one drive source. The clutch means includes a motor member, a driving gear rotated by being connected to the motor member, a first connecting gear rotatably installed on the main deck and connected to the sub deck, and a second connecting gear rotatably installed on the main deck, A second connecting gear provided at a position relatively lower than the first connecting gear, a cam member rotatably installed on one of the first and second chassis members and having a predetermined cam groove, And a second connecting gear which is rotatably installed at the other end of the pivoting lever so as to be engaged with the driving gear in accordance with the rotation of the pivoting lever, A shaft fixedly attached to the main deck and penetrating through the pivoting lever and coupled with the clutch gear so as to be able to ascend and descend, A multiple stroke control is characterized in that it comprises a spring member for resiliently biasing the shaft in the axial direction.
