Radiation image readout apparatus

A radiation image readout apparatus comprising a readout portion for reading out the radiation image data cumulatively recorded on a stimulable phosphor sheet, and an erasing portion for erasing the radiation energy remaining on said stimulable phosphor sheet after the radiation image data has been readout therefrom, further comprising

• a mode input means capable of selecting and inputting an erase-only mode wherein the readout operation is not performed by the readout portion and only the erasing operation is performed by the erasing portion, and the operation is complete, and
• a mode control means for controlling, based on the mode input at the mode input means, the selection of whether or not the readout portion and the erasing portion are to perform each of said operations or not, and
• an erasing energy level detection means for detecting, at least when said erase-only mode is the operational mode, the erasing energy level required to erase the radiation energy remaining on a stimulable phosphor sheet that is to become the object of the erasing operation,
• wherein, based on the erasing energy level detected by said erasing energy level detecting means, said erasing portion performs the erasing operation on said stimulable phosphor sheet.
