Filed: 1984-03-09
Abstract: PURPOSE:To obtain an excellent reproduced image by providing an excited light reflection preventing film on the incidence end surface of a light converging body and further arranging a light converging mirror which reflects accelerated phosphorescence, but does not reflects excited light near where the excited light makes a scan. CONSTITUTION:A storage type phosphorescent material sheet 3 is irradiated with scanning laser light 1b to cause accelerated phosphorescence at the irradiated position on the sheet 3 to intensity corresponding to image information, and its emitted light is guided from the incidence end surface 4a of the light converging body 4 to a photomultiplier tube 5 through the light converging body 5 and converted into an electric signal to read the image. The excited light reflection preventing film 13 is formed on the incidence end surface 4a for the excited light 1b and the light converging mirror 10 is arranged along the scanning part while having the reflecting surface 10a opposite the incidence end surface 4a, so that the reflecting surface 10a reflects the accelerated phosphorescent light, but does not reflect the excited light. Therefore, the excited light which illuminates the sheet 3 and is reflected there is never incident on the sheet again, so accurate image information is obtained.
