ABSTRACT:
A radiation image read-out apparatus comprising: scanner for scanning stimulable phosphor sheets with a beam of stimulating light, read-out device for detecting light emitted from the stimulable phosphor sheet and producing an electric image signal, sheet discriminator for discriminating between different types of phosphor sheets, stimulating light regulator for regulating the amount of stimulating light projected onto the stimulable phosphor sheet per unit area thereof during scanning and/or gain regulator for regulating the conversion gain of the read-out device, and control apparatus responsive to the output of the sheet discriminator for controlling the stimulating light regulator and/or the gain regulator to cause the read-out device to produce identical image signals in response to different amounts of light emitted by different types of phosphor sheets having radiation images recorded thereon under the same conditions. A radiation image read-out and/or erasing apparatus comprising: energy level detector for detecting the energy level stored by the stimulable phosphor sheet at the time of read-out and/or sheet discriminator for discriminating between different types of phosphor sheets, and control apparatus responsive to the output of the energy level detector and/or the sheet discriminator for controlling the amount of erasing light projected onto the stimulable phosphor sheet.
