마이크로프로세서(1)의 단자(P1)(P2)에 일정시간계수용 발진펄스를 제공하는 수정발진기(X)와, 단자(P11)로부터의 출력이 인버터(I3)를 통해 연속구동하는 트랜지스터(Q3)(Q4)를 구동하여 모타(M1)(M2)의 구동을 제어하게 한 모타구동 제어부(3)와, 단자(P10)(P12)로부터의 출력이 각각의 인버터(I1)(I2)(I4)(I5)를 통해 트랜지스터(Q1)(Q2)(Q5)(Q6)를 구동하여 상기 모타(M1)(M2)의 구동방향을 제어하게 한 모타구동 방향제어부(2)(4)와, 포토커플러(PC1)를 통해 감지된 프린트 휠 상태가 연산증폭기(OP1)를 통해 단자(P13)에 인가되게 한 프린트 휠 상태감지부(5)와, 단자(P14)로부터의 출력이 트랜지스터(Q7)를 통해 부저(BZ)를 구동하여 상기 프린터 휠의 오장착시 경보를 발생하게 한 경보발생부(6)로 구성하여, 프린트 휠 데이타로 선택되면, 상기 단자(P10-P12)로부터의 출력으로 상기 모타(M1)(M2)를 구동하고, 일정 시간 후 상기 포토커플러(PC1)를 통해 단자(P13)로부터의 데이타를 판별하여, 고전위로 되면 상기 프린트 휠의 정상 동작상태로 판별한 후 다음 루틴을 수행하며, 저전위로 되면 프린트 휠의 오동작상태로 판별한 후 상기 모타(M1)(M2)의 구동을 정지하고, 단자(P14)로부터의 출력이 상기 부저(BZ)를 구동하여 경보를 발생하는 것을 특징으로 하는 데이지 휠 타이프라이터의 프린트 휠 장착상태 감지방법.Crystal oscillator X for providing a constant time counting oscillation pulse to terminals P1 and P2 of microprocessor 1, and transistor Q3 whose output from terminal P11 is continuously driven through inverter I3. The motor driving control section 3, which has driven Q4 to control the driving of the motors M1 and M2, and the outputs from the terminals P10 and P12 are respectively inverters I1, I2, and I4. A motor driving direction control unit (2) (4) for driving the transistors (Q1), (Q2), (Q5) and (Q6) through (I5) to control the driving direction of the motor (M1) (M2); The print wheel state detection unit 5, which causes the print wheel state sensed through the PC1 to be applied to the terminal P13 through the operational amplifier OP1, and the output from the terminal P14 through the transistor Q7. And an alarm generator 6 which drives the buzzer BZ to generate an alarm when the printer wheel is incorrectly mounted, and when selected as print wheel data, outputs from the terminals P10-P12 to the module. After driving the other M1 and M2, and after a predetermined time, the data from the terminal P13 is determined through the photocoupler PC1. When the low potential is reached, the motor is determined to be in a malfunction state of the print wheel, and then the driving of the motors M1 and M2 is stopped, and the output from the terminal P14 drives the buzzer BZ to generate an alarm. A method for detecting print wheel mounting of a daisy wheel typewriter. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
