Abstract
본 발명은 테이프가 늘어진 상태이거나 전원 전압이 안정되지 못하여 재생에 의한 영상 및 음향이 비정상적으로 변질되어 출력되는 경우 이를 검지하여 재생 속도를 자동으로 보정할수 있도록 된 재생 속도 자동보정기능을 갖춘 테이프 재생장치에 관한 것으로, 마그네틱 테이프에 기록되어진 영상 또는 음성신호를 재생하는 테이프 재생장치에 있어서, 소정 제어 명령에 따라 테이프 재생동작을 실행하는 데크와, 이 데크를 구동 제어하여 테이프의 재생 속도를 조절하는 서보제어수단, 재생신호내에 포함되어 있는 소정주기의 기약정 신호를 검지하기 위한 기약정신호 검지수단, 이 기약정 신호 검지수단에 의한 기약정신호 검지여부에 따라 테이프에 기록된 기약정신호와 동일한 주기의 신호를 발생하는 주기 신호 발생수단, 상기 기약정신호 검지수단과 상기 주기 신호 발생수단으로부터 출력되는 신호의 위상을 비교하여 위상차에 해당하는 소정 차신호를 출력하는 위상 비교기, 및 이 위상 비교기로부터 출력되는 차신호를 근거로 상기 데크 구동부를 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.The present invention provides a tape reproducing apparatus having an automatic reproducing speed correction function to automatically correct a reproducing speed by detecting a case where a tape is stretched or a power supply voltage is not stabilized so that an image and sound are reproduced abnormally. A tape reproducing apparatus for reproducing a video or audio signal recorded on a magnetic tape, the tape reproducing apparatus comprising: a deck for executing a tape reproducing operation according to a predetermined control command, and a servo for controlling the deck to control the reproducing speed of the tape. A control means, a promise signal detection means for detecting a promise signal of a predetermined period included in the playback signal, and a signal of the same period as the promise signal recorded on the tape depending on whether the promise signal is detected by the promise signal detection means. Period signal generating means for generating, the commitment signal detection number A phase comparator for comparing a phase of a signal output from the periodic signal generator and outputting a predetermined difference signal corresponding to a phase difference, and control means for controlling the deck driver based on the difference signal output from the phase comparator. Characterized in that configured.
