ABSTRACT:
A stimulable phosphor sheet carrying a radiation image stored thereon is mounted on a first rotary plate, and a stimulating light beam is projected onto the sheet while the first rotary plate is rotated, thereby effecting main scanning of the sheet by the stimulating light beam. The stimulating light beam is moved relative to the first rotary plate in a radial direction of the first rotary plate to effect sub-scanning of the sheet by the stimulating light beam. Light emitted by the sheet upon stimulation by the stimulating light beam is photoelectrically detected by a photoelectric converter, thereby obtaining an image signal. Recording light beam is modulated on the basis of the image signal, and the modulated recording light beam is projected onto a recording medium mounted on a second rotary plate while the second rotary plate is rotated in synchronization with the main scanning of the recording medium by the stimulating light beam to effect main scanning of the recording medium by the recording light beam. The recording light beam is moved relative to the second rotary plate in a radial direction of the second rotary plate in synchronization with the sub-scanning of the sheet by the stimulating light beam to effect sub-scanning of the recording medium by the recording light beam.
