摘要： PURPOSE:To improve the measurement precision, by connecting the first displacement meter and the second displacement meter, where a positional relation to the first displacement meter is fixed, to a supporting member as one body and providing a plane reference standard which is always brought into contact with the measurer of the second displacement meter. CONSTITUTION:Three long screw rods 4a-4c and short screw rods 5a-5c are planted on a moving table 2, and supporting plates 8 and 9 are fixed by nuts 6 and 7. A supporting member 11 which supports a material 10 to be measured is fixed on the supporting plate 8, and a plane reference standard 12 is fixed in the position just under the supporting member 11 under the supporting plate 9. Displacement meters 13 and 14 which have measurers 13a and 14a movable in the axial direction are arranged oppositely to each other on the same line, and measurers 13a and 14a are brought into contact with the material 10 to be measured and the plane reference standard 12. When the moving table 2 moves, measurers 13a and 14a slide on the material 10 and the plane reference standard 12, and the extent of mechanical displacement of measurers at each point is outputted as electric signals A1 and B1. Thus, an accurate value A0=A1+B1 is obtained independently of play of a guide mechanism.

摘要： PURPOSE:To obviate a change in the range where focusing is approved even if the luminance distribution of an object, the F value of a lens, etc. change, by comparing three sets of photodetected outputs corresponding to different depths of focus. CONSTITUTION:Three line sensors 5a-5c are so disposed that the limit point N where focusing on a front focus side is approved and the limit point F where the focusing on a rear focus side is approved are positioned respectively at the intermediate of the sensors 5a and 5b and at the intermediate of 5b and 5c. The photodetected outputs of the sensors 5b and 5a are compared in a comparator 13 and the photodetected outputs of the sensors 5b and 5c in a comparator 14. Gates 17-19 are controlled by the results of the comparison, the results of the comparison through inverters 15, 16, etc., and the respective imaging states such as within the range where the focusing is approved, too shallow depth of focus and too deep depth of focus are displayed by LEDs 7c, 7a, 7b. Even if the luminance distribution of the object, the full aperture F value of the lens used, etc. change, the change in the range where the focusing is approved is obviated and the arithmetic circuit is simplified.

摘要： PURPOSE:To establish the range where the depth of focusing is approved and to enable the detection of the deviation between an image-formation point and a film plane, by determining the function corresponding to the contrast value in the detection of a photodetecting part and further determining the image- formation point. CONSTITUTION:The transmitted light of a main mirror 1 is totally reflected by an auxiliary mirror 3 and is made incident to a beam splitter 4, by which the light is trisected. The splitter 4 has semitransparent parts 4a, 4b, and a total reflection part 4c, and the energy of the luminous fluxes are equal to each other. A range finding element 5 has three line sensors 5a, 5b, 5c, to which the light of the splitters 4a-4c are respectively inputted. The contrast value Y indicating the sharpness of the photographing light near the image-formation point peaks at the image-formation point and decreases as it moves further from said point. If the entire part of the contrast curve is known, the peak position thereof is known and the peak position, i.e., the image-formation point is determined from the X-coordinates thereof.
