Abstract

본 발명은 사용자가 소망하는 노래를 반복하여 청취하기 위해 자동반복키를 조작한 경우 자기테이프상의 연속적인 오디오정보기록구간사이에 존재하는 무음구간을 검출해서 자동반복재생이 가능하도록 하기 위한 카세트테이프레코더의 자동반복재생장치에 관한 것으로, 사용자가 반복재생시키고자 희망하는 노래를 지정할 수 있는 자동반복버튼부(10)와, 상기 자동반복버튼부(10)상의 자동반복키조작시 그에 따른 자동반복재생모드 또는 자동반복해제모드가 일시 기억되는 모드기억부(20), 오디오테이프를 희망하는 동작상태로 구동시키는 데크메카니즘(30), 오디오테이프상에 존재하는 무음구간을 검출하기 위한 신호음검출수단(40) 및, 자동반복재생모드시 상기 신호음검출수단(40)에서 검출되는 신호레벨을 기준데이터와 비교하여 상기 데크메카니즘(30)의 구동을 제어하는 제어수단(50)으로 구성된 것이다.The present invention provides a cassette tape recorder for detecting a silent section existing between continuous audio information recording sections on a magnetic tape when the user operates the automatic repeat key to repeatedly listen to a desired song. An automatic repeat playback apparatus for an automatic repeat button, wherein the user can designate a desired song to be repeatedly played, and the automatic repeat key operation on the automatic repeat key operation on the automatic repeat button section (10). A mode memory section 20 in which the mode or the auto-repeat release mode is temporarily stored, a deck mechanism 30 for driving the audio tape to a desired operation state, and a signal sound detection means 40 for detecting a silent section existing on the audio tape. And the deck mechanism by comparing the signal level detected by the signal sound detecting means 40 with reference data in the automatic repeat playback mode. Is composed of control means 50 for controlling the drive (30).

Claims

The automatic repeat button unit 10, which allows a user to designate a desired song to be repeatedly played, and the automatic repeat play mode or the automatic repeat play mode according to the automatic repeat key operation on the automatic repeat button unit 10 temporarily. A mode memory 20 to be stored, a deck mechanism 30 for driving the audio tape to a desired operating state, a signal sound detecting means 40 for detecting a silent section existing on the audio tape, and an automatic repeat playback mode. And a control means (50) for controlling the driving of the deck mechanism (30) by comparing the signal level detected by the silent section detecting means (40) with reference data.

The A / D converter (51) for digitally converting the audible signal sound from the tone detection means (40), and the reference data which can be compared with the digitally converted data are stored. The comparison data storage unit 52, the comparison unit 53 for comparing the digitally converted data with the reference data, and the comparison result of the comparison unit 53, While the rewind operation is continued, when the two comparison data are the same, the control unit 54 controls the driving of the tape reel so that the audio tape is reproduced and the tape reel driving control signal from the control unit 54. An automatic repeat playback apparatus for a cassette tape recorder, comprising a tape reel driver (55) for driving a tape reel.

3. The automatic repeating playback apparatus of a cassette tape recorder according to claim 2, wherein the reference data on the comparison data storage section (52) is set as detection signal data in a silent section.
