ABSTRACT:
In a radiation image read-out apparatus, a stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The light, which is emitted by the portion of the stimulable phosphor sheet exposed to the stimulating rays, is photoelectrically detected, and an image signal representing the radiation image is thereby obtained. A plurality of laser beam sources produce laser beams, which serve as the stimulating rays. A beam combining device combines the laser beams, which have been produced by the laser beam sources, such that the beam spots of the laser beams are superposed one upon another on the stimulable phosphor sheet. A beam number reducing device prevents the laser beams, except for a single laser beam, from impinging upon the stimulable phosphor sheet.
