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.
