<p><P>PROBLEM TO BE SOLVED: To provide a small spectrophotometer of low cost for performing color measurements of an output printed matter in-line. <P>SOLUTION: In a system 300, a collimating lens is not arranged between a refractive index distribution type lens 304 and a linear and adjustable filter 306, and the linear and adjustable filter 306 is separated from a linear sensor 308 by a clearance G. An irradiation device 301 has a light beam irradiated toward a toner image 302A on an image support surface 302. The linear sensor 308 receives the light beam reflected from the toner image 302A on the image support surface 302. The light beam reflected from the toner image 302A on the image support surface 302 is turned to the linear sensor 308 by the refractive index distribution type lens 304. The refractive index distribution type lens 304 is arranged between the image support surface 302 and the linear and adjustable filter 306. The linear and adjustable filter 306 is arranged between the linear sensor 308 and the refractive index distribution type lens 304. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
