Title: Copying device
Inventor: KOIDE JUN
IPC: G02F1/37
Filed: 1989-03-01
Abstract: PURPOSE:To reproduce an object color density with the density of light having a wavelength within the wavelength band of the spectral sensitivity distribution of a photosensitive body by providing a copying device with a wavelength conversion means for absorbing a specific wavelength component or components in a specific wavelength band from light diverging from an object and for emitting light of other specific wavelengths or light in other specific wavelength bands. CONSTITUTION:An original 3 illuminated by a light source lamp 1 allows the light having a wavelength which corresponds with picture information thereon, to pass through and diverge from the original 3, and the light is made incident on the wavelength conversion means 4. With respect to the spectral distribution of the light made incident on it, its fluorescent material absorbs the component of a wavelength band shown by (a) and emits the light of spectral distribution shown by (b) since the means 4 is made of fluorescent material such as perylene-based material. Consequently, the light which is in a visual sensitivity wavelength band shown by (e) but is out of the spectral sensitivity distribution band of the photosensitive body is wavelength-shifted into the sensitivity wavelength band of the photosensitive body by the wavelength conversion means 4. Thus, the photosensitive body 7 can monochromatically react to a picture having the same density as the original 3 seen with eyes.
