테이프 레코더의 카운터 메모리 재생방법How to Play Counter Memory in a Tape Recorder

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

첨부된 도면은 일반직인 테이프 레코더의 카운터 메모리 재생 장치에 대한 블럭구성도이다.The accompanying drawings are block diagrams of a counter memory reproducing apparatus of a general tape recorder.

Claims (1)

회전하여 테이프가 풀리고 감기는 테이프 공급측 및 감는측 릴(1),(2)과 각각의 공급측 및 감는측 릴허브(3),(4)에 의해 펄스가 발생되는 포토 인터럽트(5),(6)와, 발생된 펄스가 파형 정형화되어 연산처리되는 파형 정형화(7),(8) 및 마이콤(9)과, 상기 마이콤(9)에서 출력되는 정보를 표시하는 표시부(11)와, 사용자의 요구에 따른 키신호를 발생하는 조작키부(10)로 구성된 카세트 레코더에 있어서, 메모리 반복재생 요구키 입력이 되면 상기 테이프 공급측 및 감는측 릴(1),(2)의 회전 펄스주기(w1),(w2)를 측정하고 연산에 의해 상기 테이프 공급측 및 감는측 릴(1),(2)의 실제 테이프 면적(SA),(SB)을 계산하여 메모리내에 저장하고, 다시 되돌림 요구가 오면 상기 각각의 값(SA),(SB)과 다시 계산된 각각의 값(SA′),(SB′)으로 연산하여 그 면적의 차이 값(SA′-SA=DA),(SB′-SB=DB)이 “0”되는 시점까지 되돌림을 반복되게 하는 것을 특징하는 테이프 레코더의 카운터 메모리 재생방법.Photo interrupts 5 and 6, in which pulses are generated by the tape supply and winding side reels 1 and 2, which are rotated to release and wind the tape, and the respective supply and winding side reel hubs 3 and 4, respectively. ), Waveform shaping (7), (8) and micom (9), in which the generated pulses are subjected to waveform shaping and computational processing, a display section (11) for displaying information output from the micom (9), and a user's request. In the cassette recorder comprising an operation key unit 10 for generating a key signal according to the present invention, a rotation pulse period w 1 of the tape supply side and the winding side reels 1 and 2 when a memory repeat playback request key is inputted; Measure (w 2 ) and calculate and store the actual tape area (S A ) and (S B ) of the tape supply and winding side reels (1) and (2) by operation, and store them in memory, The difference value (S A '-S) of the area is calculated by calculating the respective values (S A ), (S B ) and the recalculated respective values (S A ′), (S B ′). A method of reproducing a counter memory of a tape recorder, wherein the repetition is repeated until a point where A = D A ) and (S B ′ -S B = D B ) is “0”. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
