Color image sensor heads for multi-function
IA6008-FA22A


"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.

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) 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.
