Radiation image erase unit for use with stimulable phosphor sheet

A radiation image erase unit for erasing a radiation image from a stimulable phosphor sheet by exposing the same to erasure light in a radiation image read-out system having an image read-out unit for radiating stimulating rays to said stimulable phosphor sheet to cause the same to emit light representative of said radiation image stored therein, and for converting said emitted light photoelectrically to an electric signal, said radiation image erase unit comprising;

• a casing including a side panel having openings defined therein;
• a plurality of erase light sources disposed in said casing;
• feed means disposed in or outside said casing for delivering said stimulable phosphor sheet to a prescribed position in said position in said casing;
• forced cooling means having outlets disposed in said openings, respectively, of said side panels and directed toward the recording surface of a stimulable phosphor sheet positioned in said casing;
• and a baffle member disposed in said casing between said erase light sources and said stimulable phosphor sheet positioned in said casing to prevent air flow from said forced cooling means projecting the phosphor sheet against said erase light sources.
