Abstract
In an image information recording apparatus, wherein a light beam is modulated by an information signal to effect recording on a recording medium, there is provided a light beam forming unit, a light beam modulator for modulating the light beam from the light beam forming unit in accordance with an image information signal, an image-forming lens for focussing the light beam from the modulator upon the recording medium, first and second corona discharge members for sensitizing the recording medium, a scanner for scanning the modulated light beam over the recording medium, and an optical system for overlaying the image information signal and other image information with respect to the recording medium. The optical system includes a mirror for selectively directing the other image information onto the recording medium at a first exposure position, which exposure position is the same as that used for the image information signal, or at a second exposure position which is downstream of the first exposure position and the first and second corona discharge members, respectively, with respect to the path of movement of the recording medium.
