Abstract
An apparatus for reading out a radiation image stored on a stimulable phosphor sheet comprises a read-out section, an erasing section, and a section for releasably holding a cassette which is capable of housing the stimulable phosphor sheet and which has one openable end, and provided with a roller for taking the stimulable phosphor sheet out of the cassette and inserting it thereinto. The apparatus also comprises a sheet conveyance system for receiving the stimulable phosphor sheet taken out of the cassette by the roller, conveying the stimulable phosphor sheet to read-out section and the erasing section, and then transferring the stimulable phosphor sheet to the roller to have the stimulable phosphor sheet housed in the cassette at the cassette holding section. The sheet conveyance distance from the leading end of the cassette, which is held at the cassette holding section, as viewed in a cassette feeding direction to a scanning position of stimulating rays at the read-out section is shorter tha the length of the stimulable phosphor sheet in the conveyance direction.
