PROBLEM TO BE SOLVED: To shorten a time necessary for reading image information when obtaining a part of image information in the image information recorded in a solid state detector. SOLUTION: An image reading area IAR which obtains as an image signal IS from a solid state detector 20 recorded image information is set. In all scanning ranges ASR of a light for reading L1 by a reading light irradiation part 5, the reading light irradiation part 5 scans at a first scanning speed SS1 set for reading in a first scanning range SR1 including the image reading area IAR set by a acquisition area setting part 7. The reading light irradiation part 5 scans at a second scanning speed SS2 faster than the first scanning speed SS1 in a second scanning range SR2 not including the first scanning range SR1.
