PURPOSE:To analyze an image the contrast of which can be confirmed with eyes, in a short time excellently, by processing electic output signals from a potentiometer fitted to a moving pointer with a predetermined program. CONSTITUTION:A tip of a measuring section 5 is matched to an objective position A by moving a reference plate 3 and the output display is made to zero by depressing a reset button 10 of a display 9. Then, in operating an operation handle 6 and depressing a switch button 7 through the movement of the section 5 to a position B, an output signal corresponding to the diameter of a void is displayed on the device 9 via a cable 8 from a potentiometer 4 and inputted to an electronic computer 11. After the measurement of void in a predetermined area is finished, data processing is done with the inputted program in the computer 11 and the result is printed out on a printer 12. |
