Abstract
An apparatus for erasing a residual image on a stimulable phosphor sheet comprises a detector for detecting the distribution of residual radiation energy in a predetermined direction, a linear erasing light source extending in the width direction of the stimulable phosphor sheet normal to the predetermined direction, a device for moving the stimulable phosphor sheet with respect to the linear light source in the predetermined direction, and a controller for controlling the linear light source and/or the movement device to adjust the light exposure amount at each portion of the stimulable phosphor sheet on the basis of the output of the detector. Or, the apparatus comprises an erasing light source comprising a plurality of light emitting elements positioned to face the stimulable phosphor sheet which is stationary, whereby illuminance is increased at a portion of the stimulable phosphor sheet where the level of residual radiation energy is high and the stimulable phosphor sheet is exposed to the erasing light at a nonuniform illuminance.
