Abstract

본 발명은 카세트테이프의 재생시 현재의 재생면에서 일정한 시간동안 무음구간이 지속되면 해당 재생면의 녹음구간이 종료된 상태로 판단해서 재생면을 절환하고, 그 절환된 재생면에서 자동으로 녹음구간을 검출하여 재생대기시간을 줄이기 위한 카세트테이프의 자동재생장치 및 방법에 관한 것으로, 사용자가 임의의 동작선택키를 조작함에 따라 카세트테이프가 이송되고 그에 따라 그 카세트테이프상에 기록된 오디오정보를 독출하여 오디오재생시키는 카세트테이프레코더에서, 신호레벨검출부(16)에서 검출되는 신호레벨로서 녹음구간인지 무음구간인지를 판단하여 무음구간에 해당하는 신호가 소정시간 이상 검출되면 현재의 재생면을 절환사캐 그 절환된 재생면의 현재위치가 녹음구간인 경우에는 고속되감기를 수행하여 녹음구간의 선두위치에서 재생이 이루어지게 되는 반면, 상기 절환된 재생면의 현재위치가 무음구간인 경우에는 신호가 검출되는 녹음위치까지 고속감기를 수행시켜 녹음구간의 선두위치에서 재생이 이루어지게 된 것이다.According to the present invention, if the silent section is continued for a predetermined time on the current playback surface during playback of the cassette tape, it is determined that the recording section of the corresponding playback surface is terminated and the playback surface is switched, and the recording section is automatically turned on the switched playback surface. The present invention relates to a cassette tape automatic playback apparatus and method for detecting a playback standby time, wherein the cassette tape is transported as a user operates an arbitrary operation selection key, thereby reading audio information recorded on the cassette tape. In the cassette tape recorder for audio reproduction, a signal level detected by the signal level detecting unit 16 determines whether it is a recording section or a silent section. When a signal corresponding to the silent section is detected for a predetermined time or more, the current playback surface is switched. If the current position of the switched playback surface is the recording section, fast rewinding is performed to start the recording section. While the reproduction be made in value, if the current position is a silent period of said switching playing surface has to perform a fast forward recording to the location in which a signal is detected becomes the reproduction performed in the start position of the recording interval.
