Though a CPU is used in this machine, since the internal operation check of the CPU
is virtually impossible, the operating descriptions of the CPU are omitted. In addition,
since the printed board is not repaired on the customer side in principle, the circuit
descriptions of the printed board are limited to rough descriptions using block diagrams.

Therefore, the circuit descriptions are provided in the following three kinds:
•
Descriptions from the sensor to the input section of the circuit board which is
provided with the control function and the drive function.
