ABSTRACT:
A radiation image read-out apparatus comprises an optical system for scanning a stimulable phosphor sheet carrying a radiation image stored therein by stimulating rays, a light guide member for guiding light emitted by the stimulable phosphor sheet upon exposure to stimulating rays, a light guiding mirror for reflecting the emitted light to the light guide member, and a photoelectric converter for detecting the light guided by the light guide member. The light guiding mirror is provided with a reflection plane which reflects the light emitted by the stimulable phosphor sheet and which does not reflect stimulating rays. Or, a filter for absorbing the stimulating rays reflected by the stimulable phosphor sheet and transmitting the light emitted by the stimulable phosphor sheet is positioned between the scanned portion of the stimulable phosphor sheet and the light guiding mirror.
