제3도는 제1도의 동작을 설명하기 위한 흐름도이다. 상술한 구성에 의거 본 발명을 제1,2,3도를 참조하여 상세히 설명한다. 먼저 정상적인 테이프 재생시(namal play)의 동작(제2도의 T1구간)설명한다. 정상적인 테이프 재생시(namal play)에서는 (A)와 같이 제3스위치(SW2)가 “오프”상태가 되므로 제3스위치(SW3)와 연동으로 동작하는 제1스위치(SW1)는 A측으로 위치하며 이때 제2 및 제4 스위치(SW2, SW4)는 연동으로 동작하는 덱크스위치(Deck Switch)로서, 제3스위치(SW3)가 “오프”상태일시 “온”되면 마이컴(1)으로 제4스위치(SW4)의 “온”신호를 인가하는 동시에 제2스위치(SW2)의 “온”동작에 의해 모터(M)를 구동시킨다. 마이컴(1)은 (C)와 같이 제1제어신호(CTL1)를 “로우”로, 제2제어신호(CTL2)를 “하이”신호로 발생하며, (F)와 같이 메모리(2)의 어드레싱 신호를 발생한다. 이떼 테이프에 기록된 음성신호는 헤드(H)에 의해 재생되고, 이 재생신호는 증폭기(OP1)를 통해 증폭되며 제1스위치(SW1)를 통해 A측 위치로 선택된 상태이므로 증폭기(OP2) 및 스피커(SP)를 통해 출력된다. 이와 동시에 마이컴(1)의 제1제어신호(CTL1)가 (C)와 같이 “로우”상태이므로 램(2)은 라이트모드(Write mode)로 동작하며 A/D변환기(3)는 제1제어신호(CTL1)에 의해 인에이블 상태로 되어 상기 증폭기(OP1)를 통한 아날로그의 음성신호를 디지탈변환하여 출력한다. 그러므로 램(2)은 상기 A/D변환기(3)의 출력을 상기 마이컴(1)의 (F)와 같은 어드레싱에 의한 해당번지에 저장하게 된다(제2도의 T1구간).3 is a flowchart for explaining the operation of FIG. Based on the above-described configuration, the present invention will be described in detail with reference to FIGS. First will be described the operation (second-degree intervals T 1) when the normal tape playback (play namal). During normal tape play (namal play), as shown in (A), the third switch SW 2 is in the “off” state, so the first switch SW 1 operating in conjunction with the third switch SW 3 is moved to the A side. In this case, the second and fourth switches SW 2 and SW 4 are deck switches that operate in conjunction with each other. When the third switch SW 3 is in the “off” state, the microcomputer 1 is turned on. By applying the “on” signal of the fourth switch SW 4 , the motor M is driven by the “on” operation of the second switch SW 2 . The microcomputer 1 generates the first control signal CTL 1 as "low" and the second control signal CTL 2 as a "high" signal as shown in (C), and the memory 2 as shown in (F). Generates an addressing signal. The audio signal recorded on yitte tape is reproduced by the head (H), the reproduced signal is so selected to the A-side position via the first switch (SW 1) is amplified by an amplifier (OP 1) amplifier (OP 2 ) And the speaker SP. At the same time, since the first control signal CTL 1 of the microcomputer 1 is in the “low” state as shown in (C), the RAM 2 operates in the write mode and the A / D converter 3 operates in the first mode. The control signal CTL 1 is enabled, and digitally converts an analog audio signal through the amplifier OP 1 and outputs the digital signal. Therefore, the RAM 2 stores the output of the A / D converter 3 at a corresponding address by addressing such as (F) of the microcomputer 1 (T 1 section in FIG. 2).

두번째로 뮤트(mute)사이의 동작을 살펴보면 (제2도의 T1과 T2구간사이) 제2 및 제4스위치(SW2, SW4)가 “오프”상태이므로 모터(M)는 동작 정지상태가 되며, 제1스위치(SW1)는 B측에 위치하게 된다. 따라서 증폭기(OP1)를 통한 음성신호는 제1스위치(SW1)가 B측에 위치하고 있으므로 스피커를 통해 출력할 수 없어 뮤트(mute)상태가 되고, 이때 마이컴(1)은 제1제어신호(CTL1)를 “하이”상태로 출력하므로 A/D변환기(3)는 디스에이블되어 연산증폭기(OP1)를 통한 음성신호를 램(2)에 저정할 수 없게 된다.Secondly, the operation between the mutes (between T 1 and T 2 in FIG. 2) shows that the motor M is in a stopped state because the second and fourth switches SW 2 and SW 4 are “off”. The first switch SW 1 is located on the B side. Therefore, since the first switch SW 1 is located on the B side, the audio signal through the amplifier OP 1 cannot be output through the speaker, and thus the mute state is muted. Since the CTL1) is output in the “high” state, the A / D converter 3 is disabled so that the voice signal through the operational amplifier OP 1 cannot be stored in the RAM 2.

세번째로 반복신호 출력과정(제2도의 T3구간)을 살펴보면 이 경우에는 제3스위치(SW3)는 “온”상태이며, 제1스위치(SW1)는 B측에 위치하며, 제2 및 제4스위치(SW2, SW4)는 오프상태이다. 이때 마이컴(1)은 (C)와 같이 제1제어신호(CTL1)를 “하이”로 출력하여 A/D변환기(3)의 동작을 중지시키고, (D)와 같이 제2제어신호(CTL2)를 “로우”상태로 출력하여 D/A변환기(4)를 인에이블 시킨다. 이때 램(2)은 (D)와 같은 제2제어신호(CTL2)에 의해 리드모드(read mode)로 동작되어 마이컴(1)의 어드레싱에 의해 전상태에서 해당번지에 기록해 놓은 음성신호를 출력하고, D/A 변환기(4)는 상기 메모리(2)의 디지탈 출력을 아날로그변환하며, 상기 D/A변환기(4)의 출력은 저항(R1), 캐패시터(C1) 및 연산증폭기(OP3)로 구성된 저역필터에 의해 여파된 후 제1스위치(SW1)의 B측에 인가된다. 이때 제1스위치(SW1)는 (B)단자에 위치 하여 있으므로 램(2)에 저장됐던 음성신호가 연산증폭기(OP2)를 통해 증폭된 후 스피커(SP)로 출력된다.Thirdly, the repetitive signal output process (T 3 section in FIG. 2) shows that the third switch SW 3 is in the “on” state, and the first switch SW 1 is located on the B side. The fourth switches SW 2 and SW 4 are in an off state. At this time, the microcomputer 1 outputs the first control signal CTL 1 as “high” as shown in (C) to stop the operation of the A / D converter 3 and as shown in (D) the second control signal CTL. 2 ) output to "low" state to enable D / A converter (4). At this time, the RAM 2 is operated in a read mode by the second control signal CTL 2 as shown in (D), and outputs the audio signal recorded at the corresponding address in all states by the addressing of the microcomputer 1. The D / A converter 4 converts the digital output of the memory 2 into analog, and the output of the D / A converter 4 is connected to the resistor R1, the capacitor C1, and the operational amplifier OP3. After filtering by the configured low pass filter, it is applied to the B side of the first switch SW 1 . At this time, since the first switch SW1 is located at the terminal (B), the voice signal stored in the RAM 2 is amplified through the operational amplifier OP 2 and then output to the speaker SP.

따라서 램(2)에 기록되어 있는 음성신호는 제3스위치(SW3)의 상태가 “오프”상태로 변하기 전까지 계속반복 출력됨을 알 수 있다.Accordingly, it can be seen that the voice signal recorded in the RAM 2 is repeatedly output until the state of the third switch SW3 is changed to the “off” state.

상술한 바와 같이 테이프 레코더에서 테이프에서 재생할 아날로그신호를 순간적으로(수초) 디지탈화하여 반도체에 기록한 후, 필요시 이를 리드하여 재생함으로써 테이프에 기록한 신호를 반복 재생할 수 있으며, 이로인하여 외국인등을 청취할시 주요내용을 반복해서 들을 수 있음으로서 교육능률을 향상시킬 수 있는 이점이 있다.As described above, an analog signal to be reproduced on a tape is instantaneously (several seconds) recorded on a semiconductor by a tape recorder, and when necessary, the signal can be repeatedly reproduced by reading and reproducing it, thereby listening to foreigners and the like. By repeating the main content, there is an advantage to improve the educational efficiency.
