Disk reversing/transporting mechanism and disk tester using the same mechanism

摘要

A disk reversing/transporting mechanism for reversing a disk in transit of the disk from a first position to a second position has a rail, a movable table movable on the rail, and a cam plate having a cam surface provided along the rail and engaged with a roller or a pin and a groove provided on the cam surface and receiving the roller or the pin. A chucking mechanism is provided on the movable table. A crank is provided on the moving table and has a crank shaft and the roller or the pin as a crank pin and is connected to the chucking mechanism. The crank shaft is rotated by a dropping of the roller or the pin in the groove and a slipping out from the groove corresponding to a movement of said movable table to rotate the chucking mechanism to thereby reverse the disk.
