摘要： In a light beam scanning system, a beam shaper shapes light beam emitted from a light source. The shaped light beam is deflected by a deflector to scan a surface in a main scanning direction. A scanning/imaging optical system causes the light beam deflected by the deflector to form an image on the surface and scan the same. The beam shaper includes a diverging optical system which converts the light beam into divergent light. The scanning/imaging optical system consists of first and second lens elements arranged in this order from the light source side and having first to fourth surfaces as numbered from the light source side and satisfies formulae, (1) -1.42 all /f GF (2) r 1GR 2GR 4GR (3) f GR1 >0, f GR2 >0 wherein f all , f GF , r 1GR , r 2GR , r 4GR , f GR1 and f GR2 respectively represent the composite focal length of the beam shaper and the scanning/imaging optical system, the focal length of the beam shaper, the radius of curvature of the first surface of the scanning/imaging optical system, the radius of curvature of the second surface of the scanning/imaging optical system, the radius of curvature of the fourth surface of the scanning/imaging optical system, the focal length of the first lens element and the focal length of the second lens element.

摘要： Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet (50), on which a radiation image has been stored, the stimulating rays causing the sheet to emit light in proportion to an amount of energy stored thereon during its exposure to radiation. Light emitted from the exposed linear area of the sheet is received with a line sensor (20) comprising photoelectric conversion devices (21) arrayed along each of a length direction of the linear area of the stimulable phosphor sheet and a direction normal to the length direction. The sheet is moved with respect to the line light source and the line sensor and in a direction different from the length direction of the linear area of the sheet. Operation processing is performed on outputs of the photoelectric conversion devices, which outputs have been obtained at respective positions of movement and correspond to an identical site on the sheet.
