ABSTRACT:
A radiation image read-out apparatus comprises a stimulating ray source for producing stimulating rays which excite a stimulable phosphor, a device for scanning the stimulating rays on a stimulable phosphor sheet carrying a radiation image stored thereon in a main scanning direction, and a fluorescent light guide member obtained by forming a sheet-shaped material containing a phosphor and disposed so that a surface of the fluorescent light guide member receives the light emitted by the stimulable phosphor sheet when the stimulable phosphor sheet is scanned by the stimulating rays. A photodetector is closely contacted with an end face of the fluorescent light guide member, and a sub-scanning device is provided for moving the stimulable phosphor sheet with respect to the stimulating rays in a sub-scanning direction approximately normal to the main scanning direction.
