■ Configuration of the Scanner Unit
The Scanner Unit has the same mechanism as that of the reader. This equipment uses a Scanner Unit that integrates an LED,
mirror, lens, and Reading Sensor to perform original exposure and reading.
Light emitted from LED is reflected by the original and reaches the Reading Sensor through the Reflection Mirror and the Lens
Unit.
Note that there is a difference in externals of the unit for the ADF and that for the reader due to the shapes of the locations where
they are installed; therefore, they cannot be exchanged.
