Patent ID: 7866053

Claim:
A sensing apparatus for sensing a mount for optical lenses, of the type comprising: a frame comprising means for immobilising the mount; a turret, mounted to be rotatable about a first axis on the frame, the first axis being intended to be placed substantially perpendicular to a mean directrix surface of the mount; a slide mounted to slide on the turret along a second axis substantially perpendicular to the first axis; a sensor mounted for sliding in the slide along a third axis substantially parallel to the first axis, the sensor being equipped with a transverse sensing member having a contact surface for contact with the mount; means for displacement of the sensor about a rim of the mount in order to displace the contact surface about the mount during the sensing of the mount, the displacement means comprising means for driving the turret in rotation about the first axis; and means for displacement of the turret in a plane substantially perpendicular to the first axis; wherein the apparatus comprises control means for controlling the means for displacement of the turret in the plane substantially perpendicular to the first axis and suitable for displacing the turret in the plane substantially perpendicular to the first axis about a central active position while the turret is driven in rotation about the first axis by the rotational drive means, during the sensing of the mount.
