7 3.2.2 key board circuit input and output signal for key board scanning are passing through j1,j2 the output signals from output port (p110-p113) of u17 are encoded signals. By passing through u25,u26(74hc138), they are decoded to key scan signals. And they are applied to key matrix via j1. When a ...

8 3.2.3. Display circuit display signals are applied to the display circuit board via j4.. The display signals for digit indication are also used for key scan signals which are decoded at u25,u26(vhc138). The decoded signals from u25,u26 are amplified at u23,u24(driver:upa80c) and applied to the dis...

9 3.2.4. Printer drive circuit printer drive circuit consists of cpu(u17),u11,u12 and u9,u10 (driver), u13 (comparator) usually, p142 outputs “l” level. When one of department key is depressed, cpu outputs printer power signal “h”(pr_pwr) from output port p142 of u17. Q3and q4 turn on. Thus the ther...
