In a built-in type radiation image recording and read-out apparatus, n number of stimulable phosphor sheets wherein n denotes a natural number of 3 or more are circulated and reused for image recording. Waiting zones or a stack zone for keeping waiting n-2 or more stimulable phosphor sheets exposed to a radiation are positioned between an image recording section and an image read-out section in the sheet advancing direction. Waiting zones or a stack zone for keeping waiting n-2 or more stimulable phosphor sheets subjected to image erasing are positioned between the image read-out section and the image recording section in the sheet advancing direction or between an erasing section and the image recording section. Or, a first sheet retaining section for stimulable phosphor sheets prior to erasing is positioned between the image read-out section and the erasing section, and a second sheet retaining section for erased stimulable phosphor sheets is positioned between the erasing section and the image recording section.
