ABSTRACT:
An apparatus for reading out a radiation image stored in a stimulable phosphor sheet comprises a scanner for scanning the stimulable phosphor sheet by stimulating rays which cause it to emit light in proportion to the radiation energy stored, a light guiding sheet for guiding the emitted light to a light output face, and a photodetector having a light receiving face for detecting the light guided by the light guiding sheet. A plate exhibiting a refractive index approximately equal to that of the light guiding sheet is closely contacted with the light output face. A first cover is closely contacted with the plate, and a second cover is closely contacted with the circumferential surface of the photodetector so that the light receiving face thereof stands face to face with the plate in spaced relation. The second cover is removably joined with the first cover in liquid-tight condition. The space between the light receiving face and the plate is filled in hermetically sealed condition with transparent liquid exhibiting a refractive index approximately equal to that of the plate.
