Abstract
A radiation image read-out apparatus comprises devices for scanning a stimulable phosphor sheet carrying a radiation image stored therein by stimulating rays in a main scanning direction and in a sub-scanning direction. A light guide member having a light input face extending in the main scanning direction and a light output face closely contacted with a photodetector is positioned above the stimulable phosphor sheet. An aperture member is positioned between the surface of the stimulable phosphor sheet and the light input face of the light guide member. The aperture member is provided with an aperture for allowing stimulating rays to impinge upon the stimulable phosphor sheet and for allowing light emitted by the stimulable phosphor sheet upon stimulation thereof by the stimulating rays to enter the light input face of the light guide member, and light shielding sections positioned adjacently to the aperture on opposite sides thereof in the sub-scanning direction.
