ABSTRACT:
A radiation image read-out apparatus comprises a stimulating ray source constituted by many point light sources for sequentially emitting stimulating rays onto a portion of a stimulable phosphor sheet carrying a radiation image stored therein, and a line sensor constituted by many solid state photoelectric conversion devices. The line sensor extends over the length of the portion of the stimulable phosphor sheet linearly exposed to stimulating rays. Light emitted by the exposed portion of the stimulable phosphor sheet is received and photoelectrically converted by the solid state photoelectric conversion devices. The stimulating ray source and the line sensor are moved with respect to the stimulable phosphor sheet in a main scanning direction normal to the array of the solid state photoelectric conversion devices, and then moved with respect thereto in the array direction each time one main scanning step is finished.
