摘要:
A method of eliminating a ghost image in an image forming process wherein a recording medium is scanned with a light beam reflected by a polygonal rotary mirror, and wherein the light beam for scanning is directed toward the rotary mirror along a path so that the angle between the path and the rotary axis of the rotary mirror is not equal to 90.degree. so as to displace the ghost image formed on the recording medium to a position out of the scanning line on the recording medium.
摘要:
An overlay recording device for recording first information and second information in a superimposed mode on a recording medium by reading out the first information from storage in a first memory and the second information from storage in a second memory, thereafter converting the respective first and second information so read out into first and second dot signals, modulating a beam with logic outputs of the first and second dot signals to thereby form a beam modulated by the first information and the second information, and scanning the recording medium with the modulated beam.
