[4] OPERATIONAL

DESCRIPTIONS

1. Paper transport mechanism

The transport motor power is transmitted to the paper exit roller and
the paper feed roller.

2. Bin up-down shifi mechanism

The bin shift motor power is transmitted to the spiral cam @ (R side)

by the timing belt and the gear, and to the spiral cam ~
the same time by the drive shaft,
The bin is shifted up or down by foword or reverse rotation of the

motor. The bin is stopped at the stop position by the one rotation

sensor attached to the spiral cam Z.
