Contour reading device comprising a force sensor

Image Number 3 for United States Patent #7500316.

A contour reading method for an item such as an eyewire for spectacles, the method using an appliance including a support for holding the item, and a rotary platform which is rotatably mounted in relation to the support about a rotational axis and carries a reading sub-set provided with a sensor consisting of a finger and a rod, the finger having a distal end. The distal end is displaced along the contour and successive positions thereof are detected. The method is characterized in that the displacement step includes a measuring step wherein the effort exerted between the platform and the rod is measured parallel to the rod, and a control step wherein the distance between the finger and the platform is controlled according to the effort in such a way that the intensity of the effort remains lower than a pre-determined threshold.
