Color image sensor heads for multi-function
IA1208-FB11A
Flatbed type Color Image Sensor Head, utilizing RGB light source uniquely developed by ROHM.
It utilizes sensor IC with resolution change function, enabling the selection of optical resolution according to the scanning
media.
zApplications
Image sensor heads are designed for multi-function equipment such as facsimiles with color scanner or multiple function
printers.
zFeatures
1) Signal amplifier is built into the image sensor IC in order to increase immunity to external noise.
2) Employing low voltage driving sensor enables 3.3V drive which is identical to the ASIC.
3) The LED light source is mounted on the same substrate as the sensor chip which allows packaging of the device with
lighter weight and smaller 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.
