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.

Claims

The tape drive mechanism 11 responsible for driving the cassette tape according to any operation selection key operation of the user's key input unit 10, and the audio head for reading audio information recorded on the transferred cassette tape ( 12) a preamplifier 13 for amplifying a signal read out from the audio head 12 by a predetermined value, an audio signal processor 14 for audio-processing and outputting an audio signal from the preamplifier 13, and the audio A cassette tape recorder having a main amplifier (15) for amplifying an audio signal from the signal processor (14) to a predetermined level and applying it to a speaker (SP), wherein the audio signal level from the preamplifier (13) is detected. A signal level detected by the signal level detection unit 16, a timer 17 providing time data for determining the end of the recording section of the cassette tape, and a signal level detected by the signal level detection unit 16. If the signal corresponding to the silent section is detected for more than a predetermined time by the timer 17, the tape driving mechanism 11 is controlled to switch the playing surface of the cassette tape to reproduce the switching surface. Automatic playback apparatus for a cassette tape, characterized in that composed of a microcomputer (18) to control the loss.

The method of claim 1, wherein the microcomputer (18) controls the tape driving mechanism (11) when switching the playing surface of the cassette tape to fasten or rewind the cassette tape at the first recording section of the switched playing surface. An automatic playback apparatus for cassette tapes, characterized in that the playback is controlled to be performed.

In a cassette tape recorder in which a cassette tape is conveyed as a user manipulates an arbitrary operation selection key and thus reads and reproduces audio information recorded on the cassette tape, the signal level detected by the signal level detecting unit 16. It is determined whether the recording section or the silent section is detected, if a signal corresponding to the silent section is detected for a predetermined time or more, the present playback surface is switched and playback is performed in the initial recording section of the switching surface. How to play.

4. The method of claim 3, wherein if the current position of the switched playback surface is a recording section, fast rewinding is performed to play at the head position of the recording section, while the current position of the switched playback surface is a silent section. In the case of the automatic playback method of the cassette tape characterized in that the high-speed rewinding to the recording position where the signal is detected to be played at the head position of the recording section.
