IPC: G03G13/01
Filed: 1981-11-26
Abstract: PURPOSE:To obtain a dichromatic image which has superior resolving power, gradations, and low-density reproducibility, by exposing an original image in complementary colors of chromatic colors A and B or black to a photoreceptor, and developing each formed chromatic latent image. CONSTITUTION:Besides uniform negative charging, primary image exposure is perfored through a blue cutting filter of red complementary color, and a black part is negative and attenuated in potential to about white and red, i.e. nearly to zero. Then, positive charging is performed to hold the black part at (0) or positive level while holding a white and a red part at higher potential than the black part. Then, secondary image exposure is carried out through a red cutting filter to allow the potential of the white part to drops below that of the red part. The drop, however, should not be caused to the level of the black level, and their absolute values are in the order of red, white, and black. They are developed with negative charged red toner and positive charged black toner as prescribed.

Abstract: PURPOSE:To improve the measurement precision by detecting deviations of the position and the distribution of a reflected light due to the inclination of an object face to be irradiated and moving an object lens in the direction vertical to the optical axis in accordance with an error signal obtained from this detection output. CONSTITUTION:The light emitted from a Zeeman laser 9 having oscillation frequencies f1 and f2 is divided into lights of frequencies f2 and f1, which are polarized in two directions of polarization, by a lambda/4 plate 10. A beat frequency f1-f2 is detected by a photodetector 12. The light of f2 reaches a photodetector 15 by a polarizing prism 13. The light of f1 is reflected on the surface of an object 16 to be measured and is reflected totally by the polarizing prism 13 and reaches the photodetector 15. A beat frequency f1+DELTAf-f2 between frequencies f2 and f1+DELTAf is attained on the photodetector 15, and DELTAf is obtained on a basis of the difference between this beat frequency and the beat frequency f1-f2 obtained on the photodetector 12 and is integrated to obtain a displacement Z. The movement of an objective lens 20 in the Z-axis direction is measured by measuring the displacement of the object to be measured. Thus, the measurement precision is improved.
