ABSTRACT:
A radiation image recording and read-out apparatus comprises a read-out and erasing unit provided with an image read-out device for irradiating stimulating rays to an image-recorded stimulable phosphor sheet and detecting light emitted by the stimulable phosphor sheet upon exposure to stimulating rays, and a device for erasing radiation energy remaining on the stimulable phosphor sheet. The read-out and erasing unit is reciprocated normal to the direction of irradiation of stimulating rays for carrying out image read-out during forward movement, and carrying out erasing by the erasing device during backward movement. The read-out and erasing unit may be provided with two erasing devices on either side of the image read-out device for carrying out image read-out by the image read-out device and erasing by the erasing device positioned on the upstream side of the image read-out device during forward movement, and carrying out image read-out by the image read-out device and erasing by the other erasing device positioned on the upstream side of the image read-out device during backward movement.
