Inventor: HIRAYAMA TAIYA
IPC: H04N1/193
Filed: 2002-10-30
Abstract: PURPOSE: To provide an image reader that can read an image with high quality even when an original platen is bent. CONSTITUTION: In the image reader where a CIS (Contact Image Sensor) 1 is pressed by a spring 5 to press a press contact member 2 into contact with a lower face of an original platen glass plate 3, the press contact member 2 is placed with a main scanning read range W of the CIS 1, concretely at a position at which a bent of the original platen glass 3 with respect to both ends of the main scanning read range W is about a half of a maximum bent. Thus, when the original platen glass 3 is bent, the CIS 1 is depressed down against the spring 5 by about a half the maximum bent within the main scanning read range W of the original platen glass 3. Thus, the optimum focal position of the CIS 1 is deviated downward, resulting that the upper face of the original platen glass 3 being the original face is maintained within a valid focal range (focal depth) of the CIS 1 within the entire main scanning read range so as to attain image reading with high quality.
