Abstract
A radiation image erase unit for erasing a remaining radiation image from a stimulable phosphor sheet includes a box-shaped casing housing erase light sources therein and having a slot for passage therethrough of the stimulable phosphor sheet into and out of the casing, and feeders mounted on the casing for delivering the stimulable phosphor sheet into the casing, positioning the stimulable phosphor sheet in a prescribed position in the casing, and delivering the stimulable phosphor sheet from the prescribed position out of the casing. A guide member having as small an area as possible for contact with the stimulable phosphor sheet is disposed in the casing. The casing has a wall spaced from the guide member and extending in confronting relation to the erase light source. When the stimulable phosphor sheet is discharged out of the casing, the wall is exposed directly to light emitted from the erase light sources which remain energized during operation of the radiation image erase unit. In operation, the stimulable phosphor sheet is sufficiently exposed to the erasure light from the erase light sources in the casing to get a remaining radiation image erased therefrom. The stimulable phosphor sheet is not adversely affected by heat radiation from the wall of the casing to guard against heat-induced damage. Therefore, radiation images can be recorded on the stimulable phosphor sheet recyclically for a long period of time.
