A radiation image recording and read-out apparatus comprises a secured stimulable phosphor sheet, a section for recording a radiation image on the stimulable phosphor sheet by irradiating radiation to the stimulable phosphor sheet from one surface side thereof, and a stimulating ray source for producing stimulating rays which cause the stimulable phosphor sheet to emit light. A scanning system is provided for two-dimensionally scanning the stimulating rays on the image-recorded stimulable phosphor sheet from the side opposite to the radiation incidence side. A first light guide member faces the stimulable phosphor layer of the stimulable phosphor sheet from the radiation incidence side, and a photodetector is coupled with an end face of the first light guide member for detecting the light emitted by the stimulable phosphor sheet and entering the first light guide member from the surface thereof. A second light guide member faces the stimulable phosphor layer from the radiation incidence side, and an erasing light source is coupled with an end face of the second light guide member.
