ABSTRACT:
A stimulable phosphor sheet, on which energy having been stored thereon during its exposure to radiation remains, is moved with respect to a plurality of fluorescent lamps, which produce erasing light. The erasing light is irradiated to the stimulable phosphor sheet while the stimulable phosphor sheet is being moved, and energy remaining on the stimulable phosphor sheet is thereby released. The plurality of the fluorescent lamps are located such that they may stand side by side with one another in a direction that intersects perpendicularly to the direction along which each of the fluorescent lamps extends. The direction, along which the stimulable phosphor sheet is moved with respect to the plurality of the fluorescent lamps, coincides with the direction along which each of the fluorescent lamps extends. Impartation of excessively high erasing energy to the stimulable phosphor sheet is thus restricted, and erasing energy efficiency is thereby enhanced.
