Radiation image read-out apparatus

摘要

In a radiation image read-out apparatus for scanning a stimulable phosphor carrying a radiation image stored therein by stimulating rays, and photoelectrically detecting light emitted by the stimulable phosphor by use of a photodetector via a light guide member, the light guide member is fabricated into a hollow tubular shape. The light guide member is positioned in face-to-face relation to the stimulable phosphor so that the longitudinal direction of the light guide member coincides with the scanning direction of the stimulating rays. The photodetector is secured to at least one end face of the light guide member. The light guide member is provided with a slit extending longitudinally for passing the stimulating rays therethrough and introducing the light emitted by the stimulable phosphor into the light guide member.
