ABSTRACT:
Disclosed herein is a radiation image information reading apparatus for reading radiation image information recorded on a stimulable phosphor sheet and erasing the remaining radiation image information from the sheet. The apparatus generally includes a reading unit, an erasing unit, a light-intransmissive device, a first filter and a second filter. In the above apparatus, the sheet is first illuminated with stimulating rays to emit light therefrom, thereby photoelectrically reading the light to produce radiation image information. Erasing light is applied to the sheet from which the radiation image information has been read to erase remaining radiation image information as the sheet is read by the reading unit. The light-intransmissive device prevents the erasing light from entering into the reading unit.
