Filed: 1988-03-17
Abstract: PURPOSE:To shorten the focal position detecting time by saving the image information corresponding to first and second separator lenses in first and second register files, respectively, comparing the contents of these register files and calculating an image interval. CONSTITUTION:Information corresponding a separator lens 1a and information corresponding to a separator lens 1b are held in a register file 8a and a register file 8b, respectively. Subsequently, an arithmetic processing unit 11 calculates the sum of (m) pieces of data obtained successively from an arithmetic circuit 10, and when an extremely high correlativity is recognized in the data stored in the register files 8a, 8b said device derives an image interval (l) from an address of the register files 8a, 8b, calculates a focal distance and drives a photographic lens driving motor.

Abstract: PURPOSE:To eliminate the generation of uneven density by measuring an interval value of a void between a photosensitive drum and a developing sleeve of a developing device, and controlling a developing bias voltage by its interval value. CONSTITUTION:A part of a laser light 10 which is scanned onto a photosensitive drum 2 is reflected to the void direction by using a reflecting mirror 5 and a lens 6.
