MB20A

`The amplifiers, resistors, capacitors, and other discrete components that were normally externally attached, are built into the sensor IC.
` Compact body and lightweight achieved by the placement of the LED light source and sensor IC on the same board.
` Uses a special ROHM developed prism that provides superior light gathering characteristics and uniform light dispersion.
` Uses a ceramic board as the base board for minimal temperature fluctuations and uniform thermal dispersion.
` This is excellent in the point of (gamma) characteristics, and it realizes clear gradation. (Exceptionally clear print quality is given by all bits conpensation in the both case of dark output and white output.)
