Contact image sensor heads Color image sensor heads for multi-function IA6008-CA11A The new compact full color contact image sensor heads are world’s smallest in its class and designed to minimize the size and weight of the scanner. The sensor chip used for the CIS is produced with the proprietary technologies of ROHM LSI circuit design and accumulated manufacturing technology of monochrome devices. This product has an excellent color reproduction capability with the high level of noise immunity with the ultra small package. It operates on 3.3 volts power supply. zApplications Image sensor heads device for multiple function facsimiles such as color scanner and multiple function printer. zFeatures 1) Signal amplifier is built in to the image sensor IC in order to increase immunity to external noise. 2) Additionally, newly developed analog memory circuit and realizes high speed scanning. 3) The LED light source is mounted on the same substrate as the sensor chip which makes it possible to package the device with lighter weight and an extremely small size. 4) With the proprietary prism, the output signal is maintained uniformly. 5) The ceramic substrate is used for excellent dimensional accuracy and thermal stability. zExternal dimensions (Unit : mm) (25) (15.5) ROHM A No.1 13.4 0.5+− 14.9±0.2 No.12 5.3±0.2 28.85 10.6±0.3 Max. 1.52-R1.5 Effective Depth 2 Note) Deflection at the top of A faces : 0 to 0.25 V-LED B-GND G-GNDVDD R-GND CLK SP VREF N.C.
