1-1. MC Unit
The MC unit controls the whole machine by the 8-bit microprocessor. It also incorporates a stepping motor, DC motor,
and solenoid driving circuit. It has a built-in DC converter which generates +5 V with the DC +24 V power supply input.
A DC +5 V power supply is used for ICs and sensors while a DC +24 V is used for driving the motor and solenoid.
The board is mounted with six microprocessors and one ROM. Of the six microprocessors, one is for main control,
three for controlling the stepping motors, one for controlling communication with the control panel, and the remaining
one for controlling communication other than the control panel. One stepping motor control microprocessor is used for
controlling two stepping motors. The ROM is a 128K-byte EPROM written with the main control program. The
stepping motor control program and communication control program are written in the built-in ROM of the respective
microprocessors. The MC unit is connected with the OP unit (control panel) by communication.
1-2. OP Unit (Control Panel)
The control panel is controlled by a one-chip 8-bit microprocessor. It is mounted with a 16-character 2-line liquid
crystal display and a jog dial. The control program is written in the built-in ROM of the microprocessor. It is connected
with the MC unit by communication.
1-3. Staple Motor
DC +24 V power supply brush motor. Drives the stapler.
1-4. Knife Motor
DC +24 V power supply brush motor. Drives the folding knife.
1-5. Folding Conveyance Motor
DC +24 V power supply brush motor. Drives the folding rollers and folding conveyance section.
1-6. Conveyance Motor
DC +24 V power supply brushless motor. Drives the main conveyance section.
1-7. Cover Switch
Normal open microswitch. When the cover is closed, contact is established. This switch is connected to the control
coil of the relay mounted to the MC unit. The contact of this relay is connected with the DC +24 V supplied to the staple
motor, knife motor, folding conveyance motor, and conveyance motor. As it is connected in this way, operating the
microswitch opens and closes the relay contact. When the top cover is opened, the DC +24 V supplied to the staple
motor, knife motor, folding conveyance motor, and conveyance motor is cut off.
1-8. Movable Table Motor
DC +24 V power supply brush motor. When the paper reference is set to “Center”, this motor drives the machine and
automatically adjusts it to the position of the upstream processing unit.
1-9. Back Jogger Unit Motor
DC +24 V power supply stepping motor. Moves the back jogger unit incorporating the back jogger.
