The quality collimating mark survey instrument null break

摘要

PROBLEM TO BE SOLVED: To provide an egg quality index inspection apparatus capable of automatically inspecting the Haugh units and yolk coefficients, which are the indices of the quality of egg, in a noncontact way, and of inspecting the quality indices in a short time with high accuracy.;SOLUTION: A light-projecting means and a light-receiving means are arranged, in such a way that the emerging direction of the parallel light of the light projection means is in parallel with the incident direction of parallel light of the light-receiving means, and one reflecting plate and another reflecting plate are made to face each other in the optical paths of the light projection means and the light reception means. The traveling direction of parallel light emerging from the light-projecting means is altered by 90 degrees by a reflecting surface of one reflecting plate, arranged at an angle of 45 degrees with respect to the traveling direction of the parallel light. The traveling direction of the parallel light, of which the traveling direction has been altered by 90 degrees, is further altered by 90 degrees by a reflecting surface of the other reflecting plate arranged at an angle of 45 degrees with respect to the traveling direction of the parallel light, to make the parallel light incident onto the light-receiving means. Units of the one reflecting plate and the other reflecting plate move horizontally with respect to the mounting base.;COPYRIGHT: (C)2008,JPO&INPIT
