Abstract

PURPOSE:To automatically convert the contour of an object to be measured into data by measuring each point on the object through control of a base carrying the object with the output of a plurality of photoelectric conversion elements provided on a projection surface while being arranged in a closed loop. CONSTITUTION:A projection machine 10 has a base 14 for carrying an object 12 to be measured and is moved in the direction of X and Y with servo motors 16 and 18. A plurality of photoelectric conversion elements 31 are provided on a projection surface 26 along a circular closed loop 100. The output of the elements 31 controls the motors 16 and 18 through a controller 36 from a position detection circuit 34 while supplied to a measuring circuit 38 with information from pulse generators 20 and 22 to be converted into data. The object 12 is detected at the positions of both ends crossing the loop 100 and moved so as to maintain the brightness ratio in the loop as specfied accordingly thereby enabling the conversion of the contour thereof into data at a high accuracy.
