Abstract
A radiation image read-out apparatus comprises a sheet holding device for holding an image-recorded stimulable phosphor sheet on a cylindrical surface, and a spinner provided with a deflection mirror for reflecting stimulating rays coming from a semi-transparent mirror to the stimulable phosphor sheet, and a condensing lens for converging the reflected stimulating rays on the stimulable phosphor sheet. The spinner rotates the deflection mirror and the condensing lens to scan the stimulating rays in a main scanning direction on the stimulable phosphor sheet, and the sheet holding device is moved normal to the main scanning direction. A detection lens converges light emitted by the stimulable phosphor sheet upon exposure to the stimulating rays, passing through the condensing lens and coming from the semi-transparent mirror. An aperture plate having an aperture allowing the passage of only the omitted light thus converged is provided at a position of convergence by the detection lens, and a photodetector is provided at the rear of the aperture plate.
