In a radiation image read-out apparatus, the line sensor has a light receiving face whose width in the transverse direction of the line portion of the stimulable phosphor sheet exposed to the line stimulating beam is such that 30% to 90% of the amount of stimulated emission corresponding to a part of the stimulated emission spreading beyond the width of the line stimulating light beam as measured on the plane of the light receiving face of the stimulated emission detecting means can be received by the light receiving face in addition to the amount of stimulated emission corresponding to the width of the line stimulating light beam.
