ABSTRACT:
A radiation image recorded in a stimulable phosphor is read out by stimulating the phosphor with a stimulating ray to have the phosphor emit light and detecting the emitted light with a photodetector. A radiation image information thus obtained is read out by a photodetector by way of a light guide member which collects the light emitted by the phosphor and guides the collected light to a photodetector. The light guide member is made of a transparent sheet having smooth surfaces for effecting total reflection. The light guide member has a linear or arcuate end to be located adjacent to a scan line of the stimulable phosphor to receive and guide the light emitted by the phosphor and an annular end to be located adjacent to the light receiving face of the photodetector. The light entering the light guide member through the flat end is guided to the annular end by repeated total reflection.
