Construction

The construction and purpose of the scanning system are shown below.
1) Original glass
This is a glass on which original is placed. The light from the exposure lamp is irradiated to the orig-
inal through this glass.
2) Carriage-1
The carriage-1 consists of the exposure lamp, inverter board, reflector, mirror-1, etc. It is driven by
the scan motor and scans an original on the glass.
- Exposure lamp
This lamp is a light source to irradiate the original on the glass (one 16 W xenon lamp).
- Inverter board
This inverter board controls lighting of the xenon lamp.
- Reflector
This is a reflecting plate to efficiently lead the light from the exposure lamp to the surface of the
original on the glass.
- Mirror-1
This mirror leads the light reflected from the original to the mirror-2 described later.
