The opto-electronic system for dimension-measuring device comprises a transparent rule ( ) comprising at least one portion provided with a succession of opaque graduations ( ), a photo-emitter ( ), a photo-detector ( ), an integrated optical bloc ( ) capable of concentrating the light beam generated by the photo-emitter ( ) on the rule portion, and of concentrating the light beam having crossed said rule ( ) on said photo-detector ( ). The optical bloc ( ), the photo-emitter ( ) and said at least one photo-detector ( ) are mounted on the same printed circuit board ( ). The rule ( ) occupies a plane perpendicular to said printed circuit board ( ). The optical bloc comprises optical surfaces disposed opposite each side of said rule ( ).

Opto-electronic system

A comparator measures and compares linear or angular dimensions. The comparator includes a metallic casing ( ), and two bearings ( ) such that a sensing probe ( ), going through said casing ( ) and worked directly into the casing ( ), can be accommodated. Two sockets ( ) of the comparator are firmly attached to the casing ( ). A measuring system of the comparator includes a mobile portion ( ) driven by the sensing probe and a fixed portion ( ) firmly attached to the casing ( ). A housing ( ) of the comparator completely covers the outer sides ( ) of the casing ( ) and is held by the two sockets ( ).
