ABSTRACT:
A radiation image read-out apparatus comprises a stimulating ray optical system for exposing a stimulable phosphor carrying a radiation image stored therein to stimulating rays, a photodetector for detecting light emitted by the stimulable phosphor upon exposure to stimulating rays, and a light guide member for guiding the emitted light to the photodetector. A dichroic optical plane which selectively reflects either the stimulating rays or the light emitted by the stimulable phosphor and selectively passes the other is positioned in an optical path or the light guide member. The stimulating ray optical system is positioned so that the stimulating rays directly impinge upon the dichroic optical plane and come out of a light input face of the light guide member positioned close to the stimulable phosphor by being reflected by or passed through the dichroic optical plane.
