Abstract
A radiation image reading and erasing apparatus for deriving image signals in such a manner that an accelerated phosphorescence fluorescent material object, onto which radiation images are accumulated and stored, is scanned with an excitation light, and an accelerated phosphorescence fluorescent light, which is emitted from the accelerated phosphorescence fluorescent material object, is received. The apparatus is designed to obtain image data free of unwanted noises, and to occupy less space. The accelerated phosphorescence fluorescent material object is irradiated with a laser beam passing through a slit member to photomultipliers through reflection between sheets. The slit member may move with up-and-down motions. The sheets are taken-up or sent out by or from the associated take-up rollers, respectively, in accordance with the movement of slit member. The apparatus also has an erasing unit with a movable reflector to erase image information from the accelerated phosphorescence fluorescent material object.
