  • Rotational angle limiting mechanism
    Patent number: 11040443
    Abstract: A Z slider includes a rotating shaft capable of at least one revolution centered on a rotation axis, in a state Where the rotating shaft supports a measurement head that is connected to a plurality of cables; a ? axis drive motor that causes the rotating shaft, to perform normal rotation in a clockwise direction and reverse rotation in a counterclockwise direction; and an oscillating link that oscillates in a state of contact with the rotating shaft when the rotating shaft is performing normal rotation in the clockwise direction and limits normal rotation in the clockwise direction that is equal to or greater than a predetermined angle, and that oscillates in a state of contact with the rotating shaft when the rotating shaft is performing reverse rotation in the counterclockwise direction and limits reverse rotation in the counterclockwise direction that is equal to or greater than a predetermined angle.
