6. CIRCUIT EXPLANATION

6-1. Power supply circuit

1. Plug the power cord into AC outlet, secondary voltage (9.65VAC) of the power transformer T1 will be appears at "A" point.

2. Then, its AC voltage is rectified by the diode bridge and change it to DC voltage.("B" point)

3. DC voltage appears more than 7V at the corrector of power transistor 2SD2396, and then the power transistor is turned on. Then VP is supplied. ("C" point)

D E

4. When the VP voltage becomes more than 3.3V, the transistor 2SD945 is turned on and then PWD signal becomes GND level. ("F" point) When the PWD signal becomes GND level, CPU knows no power failure.

5. VP is supplied at the DC DC converter trans T2, the DC DC converter makes display and logic circuit voltage.

VN ,VF1,VF2 : Display voltage ("I", "J" point ) VDD : Logic circuit voltage ("H" point)

Transistor 2SD1803 is used for oscillating the primary voltage of DC DC converter trans.

2. Mode switch position : REG, display 0.00

3. Put in the memory protection batteries.

4. Plug out : Plug out the power cord , the memory protection batteries in.

6-2. Reset circuit

VDD

S-80728AN

When the voltage level at the pin no.17 of CPU is not stable, CPU does not work properly. To make a stable voltage, the reset IC(S-80728AN) is used for this circuit. In case the voltage level of VDD becomes down

GND

output terminof reset IC is out the stable voltage.

EEPROM is a memory to possible write/erase by electricity . The BR93LC46A privides efficient nonvolatile read/write memory arranged as 64 registers of 16 bits each. (64 words X 16 bits = 1024 bits)

[Data reading procedure]

Address

When the CPU read the dara of EEPROM, CPU send the CS signal and SK signal to EEPROM. Then, CPU send the address to EEPROM, and then EEPROM send the data to CPU.

Data

Output data here

[Data writing procedure]

When the CPU save the data to EEPROM, CPU sends the CS and SK signal to EEPROM. And CPU send the address and data to EEPROM from pin No.15. When the EEPROM writes the data , EEPROM outputs the busy signal from DO terminal to CPU. After finish writing, EEPROM outputs the ready signal from DO terminal to CPU.

Pin No.62

Pin No.63

When the CPU start printing, CPU send MD signal to rotate motor unit. Then the printer send back the RP(reset pulse),PT and PT (Timing pulse) to CPU. After CPU receive RP,PT andPT, CPU knows the position of printin wheel. And then, CPU send HD signal to operate the printing magnet when the character selected. The CPU counts the TP signal to select the character.
