(5) Driver circuit (Solenoid, magnetic clutch)
1 General
The control signals of each load outputted from the CPU and I/O
cannot drive the load directly. The output, therefore, is delivered to
the load through the driver IC.
2 Operation
The driver circuit forms a Darlington circuit with two transistors to
obtain a large drive current (load current) from a small input current
(I/O output current). When the driver input voltage is HIGH (+5V), the
transistor is turned on to flow a current in the arrow direction, operat-
ing the load. When the driver is turned on, the driver output pin
voltage is 0V.
(6) Stepping motor drive circuit

(7) AE (Auto Exposure) sensor circuit
The AE circuit is composed of the AE sensor PWB which is com-
posed of the photo diode, and the I-V convertor circuit, and the
amplifier circuit on the control PWB.
Operation amplifier A performs I-V conversion of the original density
level (minute current) from the sensor. Operation amplifier B amplifies
the output of operation amplifier A to a suitable level for inputting to
the CPU.
The amplifying level is automatically set by selecting the AE gain
signal (AEG0 ~ AEG2) outputted from the CPU when simulations SIM
47 is executed.
AE operation is performed by the software in the control PWB. When
a reflected ray enters the sensor, a voltage corresponding to the light
quantity is inputted to the CPU. The CPU compares the input voltage
and the copy lamp application voltage and controls the copy lamp
voltage so that the exposure level corresponds to the original density.
