others), or equivalent.
2nd (second) version:
CPU(IC201): NEC UPD78F1174 or UPD78F1178 is the 16-bit microprocessor.
The CPU builds in FROM and RAM.
The program is written in at FROM and memory does the store in
RAM.
UPD78F1174: 128K byte-FROM, 8K byte-RAM
UPD78F1178: 512K byte-FROM, 30Kbyte-RAM
RAM (IC203): 128K bit CMOS static RAM (manufactured by Renesas and others),

2. General Construction
2.1 Basic Assemblies
This typewriter consists of the following five major assemblies.
1) Chassis frame and platen
This assembly consists of the carrier motor, the LF (line feed) motor, the carrier drive
mechanism, and the platen.
2) Input circuit and control PCB
This assembly consists of the transformer, input circuit, and the control PCB (printed circuit
board).
3) Carrier
This assembly consists of the ribbon feeder, lift mechanism (correction feeder), ribbon motor,
hammer solenoid (printing mechanism), selection mechanism, and left end switch.
4) Keyboard
This assembly consists of the keyboard panel, membrane sheet, keyboard support panel, and
key tops.
5) Housing
This assembly consists of the main cabinet, top cover, paper stand, cord cover, bottom cabinet,
LCD cover, and LCD.
2-1

2.2 Electronic Assemblies
The basic configurations of the electronic assemblies are described below:
1) Input circuit
This assembly supplies voltage through the power cord, transformer, and power switch.
2) Control PCB (power supply smoothing circuit and drive circuit)
In the power supply smoothing circuit AC voltage is transformed into DC voltage. In the drive
circuit, the ICs (such as the CPU and SRAM) and transistors drive and control the stepping
motors, hammer solenoid, etc.
The store data is stored in SRAM.
The LCD displays text and information on functions.
3) Keyboard
The keyboard assembly consists of the keyboard panel, membrane sheet (8 × 8 key matrix),
keyboard support panel, and key tops.
4) Actuator and left end switch
The carrier, platen, selection, and ribbon/correction tape mechanisms are driven by four
stepping motors, while the hammer solenoid (printing mechanism) moves the hammer.
The left end switch detects the carrier home position and reports it to the CPU.

2.3 Components and General Operation
Original version (Control PCB:Artwork No. 999-32300)
The control PCB includes the CPU (IC201), the gate array (IC202), the EP ROM (IC203)
programmed with the data necessary for typewriter operation, the SRAM (IC205) that holds the
store data, and their peripheral devices. If the unit is equipped with the spelling checker function,
the control PCB is also equipped with a ROM (IC204).
When the power is turned on and the initial operations are completed, the CPU (IC201) begins key
scanning the keyboard through the gate array (IC202). If key input is deemed to have been made,
the CPU (IC201) reads the data concerning the printing impression for that key, the step angle for
the motor, etc., from ROM (IC203). The excitation phasing of the selection motor, carrier motor,
ribbon motor and LF motor is controlled by this data, and the hammer solenoid is turned on.

2nd version (Control PCB:Artwork No. 999-35810)
The control PCB includes the CPU (IC201), the FROM built-in CPU (IC201) programmed with the
data necessary for typewriter operation, the SRAM (IC203) that holds store data, and their
peripheral devices. If the unit is equipped with the spelling checker function, the CPU (IC201) is
equipped FROM in 512K byte.
When the power is turned on and the initial operations are completed, the CPU (IC201) begins key
scanning the keyboard. If key input is deemed to have been made, the CPU (IC201) reads the
data concerning the printing impression for that key, the step angle for the motor, etc., from FROM
in CPU (IC201). The excitation phasing of the selection motor, carrier motor, ribbon motor and LF
motor is controlled by this data, and the hammer solenoid is turned on.
