Abstract:
A radiation image read-out apparatus, comprising:i) main scanning means for scanning a stimulable phosphor sheet, on which a radiation image has been stored, with stimulating rays in a main scanning direction, the stimulating rays causing the stimulable phosphor sheet to emit light in proportion to an amount of energy stored thereon during its exposure to radiation,ii) sub-scanning means for scanning the stimulable phosphor sheet in a sub-scanning direction, which is approximately normal to the main scanning direction,iii) read-out means for photoelectrically detecting the light, which is emitted by the stimulable phosphor sheet when the stimulable phosphor sheet is scanned with the stimulating rays in the main scanning direction, and obtaining an image signal representing the radiation image,iv) a light guiding mirror for reflecting the emitted light toward the read-out means, the light guiding mirror being located to extend in the main scanning direction at a position in the vicinity of a position on the stimulable phosphor sheet, which position is scanned with the stimulating rays in the main scanning direction, andv) support means for supporting the light guiding mirror,wherein the support means is formed from a metallic material and is electrically isolated from a ground.
