Image sensor heads for narrow-width scanners
IA2004-CE10A


Equipped with the sensor chips that have built-in analog memory, this compact color image sensor head is suitable for
any scanning application that requires raped scanning of widths of up to A6. It best fits into the photo graphic applications.

Applications
Check readers, card scanners, and a variety of other image input devices.

Features
1) By integrating the signal amplifier on the sensor chip, external noise is shut out. Additionally, newly developed analog
memory circuit and realizes high speed scanning.
2) 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.
3) With the proprietary prism(reflectors), the output signal is maintained uniformly.
4) The ceramic substrate is used for excellent dimensional accuracy and thermal stability.
Variation and maximize the image re-productivity.
