To read a radiation image fast without simply increasing the quantity of stimulating light.

A radiation image reader is equipped with an exciting means of for making radiation image information stored and recorded in a radiation image conversion panel stimulatedly emit light, with a plurality of exciting light beams scanning the radiation image conversion panel in the horizontally scanning direction, a photoelectric transducing means comprising a plurality of photoelectric transducing elements which photoelectrically transduce the plurality of stimulatedly emitted light beams generated corresponding to the plurality of exciting light beams from the exciting means to generate pixel signals corresponding to the radiation image information respectively, a vertical scanning means of relatively moving the exciting means and photoelectric transducing means, or/and the radiation image transducing panel in the vertical scanning direction nearly orthogonal to the horizontal scanning direction, and an image generating means of generating radiation image signals with the pixel signals from the plurality of photoelectric transducing elements.
