PURPOSE:To obtain the title inspection apparatus having high accuracy and high processing capacity, by forming one line on a chip part to rotate said chip part. CONSTITUTION:A signal is applied to an X-axis direction drive circuit part 15 and a Y-axis direction drive circuit part 13 from a control part 11 to drive an X-axis direction drive part 16 and a Y-axis direction drive part 14 to move an X-Y table 8 and a plurality of the chip parts 6 on a printed circuit board 7 are set so as to enter a line projection range. A line rotates by rotating a slit rotary part 2 by a rotary driving part 3 and is read by the image pickup part 5 arranged to the diagonally upward part of said line and the image signal obtained is subjected to image processing and converted by an A/D converter 9 to take out only a line pattern. Next, the position of the outer edge part of each chip part 6 is detected from the line pattern by a detection circuit 10 and required operation is performed on the basis of the position of the desired code present in an imaginary range to discriminate the mount state of the chip part. By this method, an inspection apparatus having high accuracy and high processing capacity is obtained.
