Abstract
A radiation image read-out apparatus comprises a main scanning system which scans a stimulable phosphor sheet, on which a radiation image has been stored, with stimulating rays in a main scanning direction. The stimulating rays cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. A sub-scanning system moves the stimulable phosphor sheet with respect to the stimulating rays in a direction approximately normal to the main scanning direction. A light guide member, which has a light input face extending along the main scanning line on the stimulable phosphor sheet, guides the emitted light entering the light guide member at its light input face to a light output face. A photodetector is connected to the light output face. Plate-shaped members are secured to the light input face at predetermined intervals, the intervals being taken in the main scanning direction, so that the plate-shaped members are erect in a direction approximately normal to the light input face and surfaces of adjacent plate-shaped members face each other.
