The frequency of light source malfunctions is reduced and inconsistencies in exposure are controlled in a readout exposure apparatus for reading out radiation image data recorded as an electrostatic image on an image detecting device. The readout exposure device includes a light source having a plurality of LED chips, a first optical element for improving the quality of the light output, and a second optical element for focusing the light passing through the first optical element on the face of the image detecting device through two cylindrical lenses. The light output from each LED chip is focused in the direction perpendicular to the lengthwise direction of the light source. By irradiation of the image detecting device by the light not focused along the lengthwise direction of the light source, a plurality of pixels are simultaneously exposed by the light emitted from each light emitting point.
A readout exposure apparatus for reading out data recorded on an image detecting device by scanning said image detecting device with readout electromagnetic radiation, comprising:
