Power Units

There are a low-voltage power unit, which consists of an AC filter circuit, low-voltage power circuit
and heater driver circuit, and high-voltage power unit which organizes a high-voltage power circuit.

(1)

Low-Voltage Power Unit

This circuit generates the following voltages:

(3)

MCON LSI
This LSI is used for inport of SENSORs and the cntrols of Pulse Motors,Cluches,FANs and
High Voltage Power Supply.

(4)

Flash ROM
The flash ROM (29F800-70) is of 8-Mbits, and PU programs are stored in it.

(5)

EEPROM
The EEPROM (NM93C66N-NW) is of 4-Kbits, and mounted on the board with an IC socket.
Correction values are stored in it.

(6)

Pulse Motor Driver
The pulse motor driver (A2919SLBTR, A3955SLBTR,MTD2005) drives the eight pulse
motors to revolve the ID and transport media.

(7)

SRAM
This SRAM (628100LG-55L) is used as working memory of the CPU.

(8)

SDRAM
This SRAM (56V16160T) is used as data memory of the DCON LSI.
