Abstract:
A radiation image information reader comprisingirradiation means for irradiating excitation light in line form to a portion of a top surface of a storable phosphor sheet storing radiation image information therein; detection means having a line detection section in which a large number of photoelectric conversion elements for detecting photostimulated luminescent light, emitted from the excitation-light irradiated line portion or a portion of a bottom surface of aid sheet corresponding to said excitation-light irradiated line portion, are arrayed parallel to said excitation-light irradiated line portion; scan means fore relatively moving one of (1) said irradiation means and detection means and (2) said phosphor sheet with respect to the other in a direction different from a length direction of said irradiated line portion; and read means for reading an output of said detection means sequentially according to said movement and then obtaining data which constituted a final image; wherein the line detection section of said detection means is constituted by a plurality of line detection sections wherein said line detection section includes a plurality of line sensors arrayed adjacent to one another in a direction parallel to said irradiated line portion; wherein said photostimulated luminescent light emitted from the irradiated line portion is detected by said plurality of line detection sections; and wherein said line sensors are arrayed so that adjacent portions in said line sensors are disposed at positions shifted predetermined distances from said adjacent portions.
