ABSTRACT:
A radiation image read-out apparatus comprises a device for holding a stimulable phosphor sheet along a cylindrical surface, an optical element for transmitting one of stimulating rays and light emitted by the stimulable phosphor sheet and reflecting the other thereof, and a spinner, which is provided with a deflection mirror and a condensing lens. The deflection mirror reflects the stimulating rays coming from the optical element toward the stimulable phosphor sheet. The condensing lens is located in the optical path of the stimulating rays having been reflected by the deflection mirror and converges the stimulating rays on the stimulable phosphor sheet. The condensing lens also converges the emitted light at a predetermined converging position. The deflection mirror and the condensing lens are rotated together to scan the stimulating rays on the stimulable phosphor sheet in a main scanning direction. The stimulable phosphor sheet is moved in a sub-scanning direction. A light receiving face of a photodetector is located at a position, at which the light having a center wavelength in the wavelength distribution of the emitted light is converged by the condensing lens.
