로직 카세트 플레이어에서의 모드별 헤드위치 감지방법Mode-specific Head Position Detection in Logic Cassette Players

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

제1도는 본 발명에 관련된 헤드위치 감지장치의 블록 구성도,1 is a block diagram of a head position sensing apparatus according to the present invention;

제2도는 본 발명에 의한 모드별 헤드위치 감지방법을 설명하기 위한 플로우 챠트,2 is a flow chart for explaining a mode-specific head position detection method according to the present invention,

제3도의 (가)는 재생시 헤드위치 및 테이프 주행상태도,(A) of Figure 3 shows the head position and tape running state during

(나)는 테이프가 한쪽릴에 완전히 감겨진 상태에서의 릴 회전주파수 관계를 나타내는 도면.(B) is a diagram showing a reel rotation frequency relationship in a state where the tape is completely wound on one reel.

Claims (1)

제어부(3)에서는 현재 모드 데이터 상태를 검출하여 재생모드이면 이어서 릴 펄스 주파수가 해당 설정치 이하인가를 검출하여 설정치 이하이면 현재 상태를 지속하고, 설정치 이하가 아니면 헤드구동을 솔레노이드(HS)를 구동시켜 헤드위치를 재생모드로 이동시키는 제1과정과, 상기 현재 모드 데이터 상태가 빨리감기/되감기 모드이면 이어서 릴 펄스 주파수가 해당 설정치 이상인가를 검출하여 설정치 이상이면 현재 상태를 지속하고, 설정치 이상이 아니면 상기 헤드구동용 솔레노이드(HS)를 구동시켜 헤드위치를 빨리감기/되감기 모드로 이동시키는 제2과정으로 이루어진 것을 특징으로 하는 로직 카세트 플레이어에서의 모드별 헤드위치 감지방법.The controller 3 detects the current mode data state and then detects whether the reel pulse frequency is lower than or equal to the set value in the regeneration mode, and maintains the current state if it is lower than or equal to the set value. If not, the controller 3 drives the solenoid HS. A first step of moving the head position to the regeneration mode; and if the current mode data state is a fast forward / rewind mode, the reel pulse frequency is detected to be greater than or equal to the set value. And a second process of driving the head driving solenoid (HS) to move the head position to a fast rewinding / rewinding mode. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
