Contact image sensor heads Color image sensor head (300dpi) IA3004-CE10A The IA3004-CE10A is a color image sensor head that uses LED chips of the three colors red, green, and blue. Through the use of ROHM’s further improvements in optical technologies and LSI circuit designing, the IA3004-CE10A provides excellent color reproducibility and noise resistance and has taken its place as the industry’s highest level compact and lightweight image sensor head. !!!!Applications Color scanners Check readers Image scanning devices !!!!Features 1) Each sensor IC is equipped with a built-in amplifier for greatly increased noise resistance. 2) Red, green, and blue LED chips are used for the light source to obtain excellent color reproducibility. 3) Uses a single power supply operational amplifier. Operation requires only a single 5V power supply. 4) Uses a ceramic board as the base board for excellent dimensional stability, and excellent stability in optical characteristics. !!!!External dimensions (Units : mm) (12.9) 14.2±0.2 1.9±0.2 18±0.5 (5) Paper feed direction 4−φ1.9 Effective Depth 7 No.1 Pixel No.1No.9 CL A 5.5±0.2 10.68±0.4 Max.2 (9.05) Max. 1.5 (15.5) (25) 124±0.5 5.5±0.3 3.1±0.3 103(Effective Reading Width : 101.6) Socket Contact : IL-Z-C3-A-15000(JAE) Socket Housing : IL-Z-9S-S125C3(JAE) VLED B-GND G-GND V DD R-GND CLK SI GND Ao No.9 No.8 No.7 No.6 No.5 No.4 No.3 No.2 No.1 SignalSignal Pin No. Pin No. Note) Diflection at the top of glass : 0~0.25 Projection to platen is positive.
