ABSTRACT:
A radiation image erase unit for erasing a residual image from a stimulable phosphor sheet with erasure light is disposed in the vicinity of an image read-out unit which converts light emitted from the stimulable phosphor sheet upon stimulation thereof into an electric signal. The irradiation image erase unit comprises a box-shaped casing having a slot for passage of the stimulable phosphor sheet therethrough into the casing, and erasure light sources disposed in the casing for emitting the erasure light. A pair of rollers is mounted on the casing adjacent to the slot for introducing the stimulable phosphor sheet into the casing. The rollers or a cover enclosing the rollers serves to prevent the erasure light from leaking out of the casing toward the image read-out unit.
