Radiation image recording and read-out apparatus.

摘要

A radiation image recording and read-out apparatus comprises an endless recording belt (50) provided with a stimulable phosphor layer; a group of rollers (41, 42 + 51, 52) around which the recording belt is applied, including two roller sections spaced by a predetermined distance from each other, for circulating the recording belt around them between the two roller sections along the direction of the predetermined distance; an image recording section (1) for exposing the stimulable phosphor layer to a radiation; an image read-out section (20) for scanning the stimulable phosphor layer carrying a radiation image stored thereon by stimulating rays; and an erasing section (30). The predetermined distance between the roller sections is 1 - 1.5 times as long as the length of the maximum single image area of the radiation image recordable at the image recording section. The image recording section faces the recording belt moving between the roller sections. The image read-out section carriers out scanning by stimulating rays for the stimulable phosphor layer present on a circumferential surface of a roller in the group of rollers.
