Color image sensor heads for multi-function
IA6008-FB10A


"Color contact image sensor" with optical system intended for Flatbed scanning. Optical technology established for
sheet-feed scanning has been further advanced for Flatbed scanning. Furthermore, a newly developed sensor with
resolution selection function provides more freedome in choosing the adequate optical resolution matching to the
application.

Applications
Image sensor heads device for multiple function facsimiles such as color scanner and multiple function printer.

Features
1) Signal amplifier is built in to the image sensor IC in order to increase immunity to external noise.
2) A low-voltage drive sensor is employed, which runs at 3.3V like ASIC
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.
