ABSTRACT:
A detecting device comprising a projecting optical system for focusing the image of an object to be examined on a focusing glass, a plurality of photoelectric elements which can be set in proper positions on the focusing glass, circuits including level adjusting circuits and for converting outputs from the respective photoelectric elements to binary logical outputs and circuits for converting these binary logical inputs to octonary logical outputs so that the slightest variations of the shape and state of the object can be easily and accurately detected. The respective photoelectric elements can be moved out of the projecting light path as required. The projecting optical system consists of an objective lens system and a projecting lens system so that a magnified erecting image of the object can be obtained on the focusing glass.
