Japanese Patent JP2532938
Kind Code:
B2
Abstract:
A radiation image read-out apparatus comprises a main scanning system which scans a stimulable phosphor sheet, on which a radiation image has been stored, with stimulating rays in a main scanning direction. The stimulating rays cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. A sub-scanning system moves the stimulable phosphor sheet with respect to the stimulating rays in a direction approximately normal to the main scanning direction. A light guide member, which has a light input face extending along a main scanning line on the stimulable phosphor sheet, guides the emitted light entering the light guide member at its light input face to a light output face. A photodetector is connected to the light output face. A stimulating ray antireflection film is overlaid on the light input face, and further, may be overlaid over any provided reflection mirror. The stimulating ray antireflection film is designed so that the reflectivity of the stimulating rays from the stimulating ray antireflection film is lowest when the stimulating rays impinge thereupon at an angle of incidence which falls within the range of 30 DEG to 50 DEG .
