A reader device (1) includes a mounting surface (5) on which a passport (7) with a page to be read (9) is placed, a light source (21, 31) for illuminating the page to be read (9), and a camera (13) for picking up an image of the page to be read (9). The light source (21, 31) is arranged outside a front area of the page to be read. The page to be read (9) contains a near-edge code positioned close to an edge of the page to be read (9). The light source (21, 31) includes an infrared LED array (23) and a white LED array (33). An infrared LED (25e) and a white LED (35f) included in the infrared LED array (23) and the white LED array (33), respectively, and located at a near-edge code position corresponding to the near-edge code are arranged closer to the page to be read than the other infrared LEDs (25a to 25d) and white LEDs (35a to 35e) in a direction perpendicular to the mounting surface (5). Thus, a reader device is provided which allows a good image to be obtained even if a relevant page of an object to be read is deformed.
