IC5 has integrated reset functions including the power on reset, the +5V abnormal fall reset, and the watch dog timer function. When the power line reaches about 0.8V by turning on, IC5 starts operation and IC5 8 pin becomes LOW to reset the CPU. The reset state is

maintained until a certain time is passed after power line’s reaching about 4.3V. The reset maintaining time id determined by the capacity of C17. It is about 100msec for this circuit. After passing the reset time, IC5 8 pin turns to HIGH to cancel reset, and the CPU resumes operation.

When the power line voltage falls to about 4.2V, IC5 8 pin turns to LOW to issue the reset signal, and the reset state is maintained as far as the power voltage is lower than about 4.3V. After about 100msec from when the power voltage reaches about 4.3V, reset is cancelled.

IC5 3 pin is the watch dog timer clock sinal input pin, and the output signal from the CPU 6 pin is used as the clock. When the CPU normally operates, the clock is regular pulse signal of 50% duty and 5msec frequency. When the CPU is hung up or in an abnormal state, the clock is not supplied. IC5 normally monitors this clock. When the clock supply is stopped, after a ceratin time, IC5 drives 8 pin to LOW to supply the reset signal. The monitoring time of clock is determined by the capacity of C17, and is about 100msec for this circuit. Hard reset is also applied from the PPC through the communication cable. In this case, CN1-5 pin is driven to HIGH or opened to reset.

This circuit is used to sense the presence of paper on the tray. CN4 is connected to the light emitting PWB, and CN5 is connected to the light receiving PWB.

1. Light emitting circuit

The signal outputted from the CPU (IC11-5 pin) at a certain frequency is inputted to IC12-11 pin, and the reversed output is inputted to the base of Q2. Consequently Q2 turns on to light the LED.

The photoelectric current flowing through PT1 becomes the base current of Q1 and operates Q1 and is converted into the output voltage by R4. Part of current flowing through Q1 is integrated by R2 and C1 and is passed to the base of Q2 to set the operating point of Q1 with Q2, PT1, and R3. (The collector potential of Q2 is set to about 1.2V)

When disturbance lights (DC light, fluorescent light, etc.) enters the light receiving element, the DC current in PT1 and Q1 tries to increase according to the disturbance lights. However, this current is passed through R2 to the base of Q2, conducting Q2. Therefore, the photoelectric current generated by disturbance lights becomes the collector current of Q2, and does not flow to the base of Q1 which has a higher impedance. In this manner, an increase in the Q2 collector current is suppressed, and the operation is controlled. (When disturbance light increases, the Q2 emitter voltage increases by R3, therefore the limit of voltage for normal operations is about 2.5V or less. If there is no disturbance light, it is set to about 0V.)

When the signal light becomes too intense, the same control is performed. R2 and C1 forms the low pass filter which allows the fluorescent light completely to pass and does not allow modulated light to pass.

The signal outputted from the light receiving PWB is DC-cut by C6 and modulated by the comparator (IC9). (It is digitally converted by the comparator, and the threshold value of the comparator is about 3.8V.) The digital signal outputted from the comparator is latched by the flip-flop (IC3).

When D (2 pin) is HIGH at the rising edge of CLK (3 pin) of the flip-flop (IC3), it is judged as "no paper" and the output Q (5 pin) becomes HIGH. When D (2 pin) is LOW (0V), it is judges as "paper present" and the output Q (5 pin) becomes LOW.

Entry port sensor (SEM1) circuit One rotation sensor (SEN3) circuit Take-out position sensor (SEN4) circuit Upper/lower limit sensor (SEN8) circuit

1) The bin home sensor (SEN2) circuit is used to sense that the tray is at the paper exit position of the first bin. The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor. The output level is normally LOW

(0V) because of light transmission. When the tray reaches the paper exit position of the first bin,the LED light is interrupted and the output of the photo transistor becomes HIGH

(+5V). Then the HIGH output is inputted to CN10-10 pin, and the converted LOW output (0V) is inputted to IC11-59 pin.

2) The Entry port sensor (SEM1) circuit is used to sense that the paper discharged from the PPC enters the sorter entrance . After sensing, it operates in the same manner as the home sensor. The signal is inputted to IC11-60 pin.

3) The one rotation sensor (SEN3) circ uit is used to sense that the tray is at a position suitable for paper exit or take-up. The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor. The output level is normally LOW

(0V) because of light transmission. When the lead cam reaches the stop position, the LED light is interrupted and the photo transistor output becomes HIGH (+5V). Therefore the HIGH level output is inputted to CN10-13 pin, and its signal is inputted to IC11-72 pin.

4) The take-out position sensor (SEN4) circuit is used to sense that the paper on the tray is at the take-up position in take-up mode. The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor. The output level is normally LOW

(0V) because of light interruption. When the paper reaches the take-up position, the LED lights in interrupted, and the photo transistor output becomes HIGh (+5V). Therefore the HIGH level output is inputted to CN10-3 pin, and the converted LOW signal is inputted to IC11-61 pin. It is about 1.2V by monitoring through connection between CN10-1 pin and IC11-63 pin, but becomes HIGH (+5V) when open.

5) Upper/lower limit sensor (SEN8) circuit is used to sense that the bin reaches the upper or lower limit by an overrun or an abnormal operation. The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor. The output level is normally LOW

(0V) because of light interruption. When the bin reaches the upper or lower limit, the LED transmits light and the photo transistor output becomes HIGH (+5V). Therefore the HIGH level output is inputted to CN9-2 pin and the converted LOW output (by IC12 is inputted to IC11-56 pin.

The bin shift motor clock sensor and the transport motor clock sensor are composed of the photo interrupter with built-in amplifier and the slit disc attached to the motor shaft to obtain pulse signals according to motor rotation. The motor rotation speed is detected by the frequency of the pulse signals, and by counting the number of pulses, the rotation amount of the motor is detected. The circuit composition of the input section in the two sensors are the same, and it forms a noise filter composed of R35 (R36) and C9 (C8).

This circuit is used to sense the sorter set state, and is connected with the microswitch. When the sorter is installed to the main body, the contact is closed. The microswitch is connected in series to +24V, and directly switches the power to each drive section. That is, each drive section is not operated if the switch is open.

When the sorter set switch is on, +24V is applied to the cathode of ZD1, and a current flows through the base of Q1, turning on Q1 to input to IC11 59 pin.

C. Motor control circuit

[a] Transport motor drive circuit

This circuit is used to drive the motor which takes paper discharged from the main body into the sorter. The drive signal (ON at LOW) outputted from the CPU is passed through the invertor (IC12.6) and the HIGH output is inputted to the MOSFET (Q5) gate, turning on Q5. As a result, a current flows through +24I/L → the motor → Q5 → PGROUND to rotate the motor counterclockwise.

Bin shi f t mot or

This circuit is used to control rotation, stop and rotating direction of the bin shift motor, and is composed of the logic IC and the pow er M O SFE T (Q 6 ∼ Q9).

The rotation, stop and rotating direction of the motor are controlled by the combination of output logics of CPU 18 pin and 19 pin. The CPU 48 pin is the PWM output pin for speed control.

First, in the normal rotation of the motor, the CPU 18 pin is LOW, 19 pin is HIGH, 48 pin is HIGH, IC10 p pin and 12 pin are HIGH. Then IC10 6 pin becomes HIGH, IC2 8 pin becomes HIGH, conducting Q7 and Q8. On the other hand, since IC10 3 pin is LOW and IC2 12 pin is LOW, Q6 and Q8 is shut off. Therefore, a current flows through +24VI/L → Q7 → CN8.1 → Motor → CN8.2 → Q8 → PGROUND to rotate the motor clockwise (when viewed from the output shaft).

Under this state, when the CPU 48 pin (PWM signal) is drive to LOW, IC10 6 pin becomes LOW to turn off Q7, interrupting power supply from +24V. However, a regenerative current generated by the motor coil inductance flows through PGROUND → Q8 flywheel diode → CN8.2 → motor → CN8.1 → Q9 → PGROUND. In this case, the motor rotates in reduced speeds. The motor speed is controlled by controlling the pulse of the power applied to the motor by adjusting the H/L duty of the PWM signal.

Next, in the reverse rotation, the CPU 18 pin is driven to LOW, 19 pin LOW, and IC10 9 pin and 12 pin HIGH, IC10 3 pin becomes HIGH and IC12 12 pin becomes LOW to turn on Q6 and Q9 and turn off Q7 and Q8. As a result, a current flows through +24V → Q6 → CN8.2 → motor → CN8.1 → Q9 → PGROUND in the reverse direction of the normal rotation, rotating the motor counterclockwise. The speed control is performed in the same manner as the normal rotation.

To stop the motor, the CPU 18 pin is driven to HIGH, IC10 3 pin and 6 pin become LOW, IC2 8 pin and 12 pin become HIGH, Q6 and Q7 are turned off, Q8 and Q9 are turned on, and the both terminals of the motor are shorted to apply the brake. In the brake mode, a strong braking torque is generated to stop the motor.

When the bin reaches the limit position, the limit sensor signal and the bin home sensor signal are combined to control the stop signal of the motor. At the upper limit, only the limit sensor senses the signal, and the limit sensor signal becomes LOW and the home sensor signal becomes HIGH.

Therefore IC4 8 pin becomes LOW, IC4 11 pin becomes HIGH, and Q7 is turned off to stop the motor. At the lower limit, both of the limit sensor and the bin home sensor sense signals, the limit sensor signal is LOW, and the home sensor signal is

LOW. Therefore IC4 11 pin is LOW and IC4 8 pin is HIGH, and Q6 is turned off to stop the motor.
