Abstract

An audio broadcast memory section (11) is connected to a microprocessor section (2), while the section (11) and a signal processing section (7) are connected through a switch (8) to an amplifier (9). The microprocessor section (2) receives introplay signals and outputs a rewinding command to detect the beginning portion of the tape. Then the beginning portion of a music is searched, and the switch (8) is switched over. Then the tape is played, 9 seconds are counted, and an address is formed by reading the music number. When 9 seconds are elapsed, the switch (8) is switched over so as for the memory section (11) to output signals, and so as for a music number audio broadcast to be outputted. Thus music numbers are searched repeatedly.

본 발명은 DAT(Digital Audio Tape Recorder)에서 테이프에 어떠한 곡이 녹음되어 있는가를 소개하도록 각 곡의 처음부분을 찾아 9초간 플레이하는 인트로플레이(INTRO PLAY)장치에 관한 것으로, 특히 카(Car) DAT에서 사용자가 운전을 하고 있는 관계로 DAT세트의 표시부를 볼 수 없어서 각 곡의 곡번호를 알 수 없는 곤란을 해결하기 위하여 각 곡 9초 플레이후에 음성으로 곡번호를 방송하여 원하는 곡번호를 알 수 있도록 한 카 DAT용 인트로플레이장치에 관한 것이다.The present invention relates to an INTRO PLAY device that finds the beginning of each song and plays it for 9 seconds to introduce what songs are recorded on the tape in a DAT (Digital Audio Tape Recorder), particularly in a car DAT. In order to solve the difficulty of not knowing the song number of each song because the user is driving, the song number of each song is broadcast. It relates to an intro play device for a car DAT.

일반적으로 종래의 DAT인트로플레이장치는 자동차를 운전하는 사용자가 인트로플레이기능을 이용하여 테이프에 어떠한 곡들이 녹음되어 있는가를 알아볼때에 표시되는 각곡의 번호를 눈으로 확인하려면 운전을 하는데 지장을 줄 우려가 있어서 곡번호를 확인하기가 곤란하다는 문제점이 있다.In general, the conventional DAT intro-play device may interfere with driving to visually check the number of each track displayed when the user driving the vehicle uses the intro-play function to find out which songs are recorded on the tape. There is a problem that it is difficult to identify the song number.

본 발명은 이와 같은 문제점을 감안하여 각 곡을 찾아 9초간 플레이한 후에 음성으로 곡번호를 방송하여 원하는 곡 번호를 알 수 있도록 하여 기능을 강화한 카 DAT용 인트로플레이장치를 창안한 것으로, 이를 첨부한 도면을 참조해 상세히 설명하면 다음과 같다.In view of the above problems, the present invention has been invented for a car DAT intro-play device which enhances a function by finding the desired song number by broadcasting the song number by voice after searching for each song and playing it for 9 seconds. Referring to the drawings in detail as follows.

제 1 도는 본 발명 카 DAT용 인트로플레이방식에 따른 장치의 블록도로서 이에 도시한 바와 같이 키입력부(1)를 마이크로프로세서부(2)에 연결하고, 그 마이크로프로세서부(2)는 메카니즘제어회로부(3)를 통해 데크메카니즘부(4)에 연결된 뒤 그 데크메카니즘부(4)를 시작/끝검출부(5)를 통해 상기 마이크로프로세서부(2) 연결하며, 상기 데크메카니즘부(4)의 헤드(H)의 출력단자를 프리이퀄라이저부(6)를 통해 상기 마이크로프로세서부(2)와 연결된 신호처리부(7)에 연결하여 그 신호처리부(7)의 출력단자를 스위치(8)의 일측단자(P1)에 접속하고, 그의 타측단자(P2)는 음성방송용메모리부(11)의 출력단자를 연결하며, 상기 마이크로프로세서부(2)를 상기 음성방송용메모리부(11)와 연결함과 아울러 상기 스위치(8)의 제어단자에 연결한 후 그 스위치(8)의 가동단자(P3)를 앰프부(9)를 통해 스피커(10)에 연결하여 구성하였다.1 is a block diagram of an apparatus according to the introplay method for a car DAT according to the present invention. As shown therein, a key input unit 1 is connected to a microprocessor unit 2, and the microprocessor unit 2 is a mechanism control circuit unit. (3) connected to the deck mechanism portion 4, and then the deck mechanism portion 4 is connected to the microprocessor portion 2 through the start / end detection portion 5, and the head of the deck mechanism portion 4 The output terminal of (H) is connected to the signal processing unit 7 connected to the microprocessor unit 2 through the pre-equalizer unit 6, and the output terminal of the signal processing unit 7 is connected to one side terminal of the switch 8 ( P1), the other terminal P2 thereof connects an output terminal of the voice broadcasting memory unit 11, and connects the microprocessor unit 2 with the voice broadcasting memory unit 11 and the switch. After connecting to the control terminal of (8), the movable terminal (P3) of the switch (8) Via the amplifier unit (9) was constructed by connecting the speaker (10).

이와 같이 종래의 DAT인트로플레이장치에 음성방송용 메모리부(11)를 첨가하여 구성한 본 발명의 작용 및 효과를 첨부한 도면을 참조해 상세히 설명하면 다음과 같다.As described above in detail with reference to the accompanying drawings, the operation and effect of the present invention constituted by adding the voice broadcasting memory unit 11 to the conventional DAT intro play apparatus as follows.

제 3 도는 본 발명 카 DAT용 인트로플레이방식의 제어 동작 흐름도이고, 제 2 도는 DAT테이프의 기록포메트(Format)를 보인 개요도이다.3 is a flowchart illustrating a control operation of the intro play method for a car DAT of the present invention, and FIG. 2 is a schematic diagram showing a recording format of a DAT tape.

먼저, 키입력부(1)로부터 인트로키신호가 입력되면 마이크로프로세서부(2)는 메카니즘제어회로부(3)를 통해 데크메카니즘부(4)의 모드를 되돌려감기(Rewind)모드로 하여 테이프의 되돌려 감기를 시킨 후 시작/끝 검출부(5)를 통하여 시작부분이 검출되면 그 마이크로프로세서부(2)가 첫곡을 찾게 된다. 여기서 시작/끝검출부(5)는 포토인터럽터(Photo interrupter)라고 하는 일반적인 광센서를 이용하여 테이프의 시작부분과 끝부분의 투명한 부분을 검지하여 논리 레벨 "0" 또는 "1"의 신호를 발생하여 시작 또는 끝을 검지하도록 되어 있다. 또한, DAT에서 어떤 곡의 첫부분을 찾는 방법은 제 2 도에서 도시된 DAT테이프의 기록포메트에는 SUB1, SUB2라는 구간이 정해져 있는데, 이 SUB코드범위내에 곡의 첫부분을 나타내는 신호(시작-ID)와 그 곡의 번호를 나타내는 신호(PNO)가 녹음시 기록되도록 되어 있어서 곡의 첫부분을 찾을때 테이프에 기록되어 있는 신호를 데크메카니즘부(4)의 헤드(H)를 통해 검출하여 프리이퀄라이저부(6)를 통해 보상한 뒤 신호처리부(7)에서 곡의 첫부분 및 그 곡의 번호를 체크하여 그 결과를 마이크로프로세서부(2)에 전달한다.First, when the intro key signal is input from the key input unit 1, the microprocessor unit 2 returns the mode of the deck mechanism unit 4 to the rewind mode through the mechanism control circuit unit 3 to rewind the tape. After the start is detected through the start / end detection unit 5, the microprocessor unit 2 finds the first song. Here, the start / end detection unit 5 detects the transparent portions at the beginning and the end of the tape by using a general optical sensor called a photo interrupter, and generates a signal of logic level “0” or “1”. It is supposed to detect the beginning or the end. In addition, a method of finding the first part of a song in the DAT is defined in the recording format of the DAT tape shown in FIG. 2 by the sections SUB1 and SUB2. ID) and the signal PNO indicating the song number are recorded at the time of recording. When the first part of the song is found, the signal recorded on the tape is detected through the head H of the deck mechanism unit 4, and the signal is pre-recorded. After compensating through the equalizer 6, the signal processor 7 checks the first part of the song and the number of the song and transmits the result to the microprocessor unit 2.

이때 곡의 처음을 나타내는 신호(시작-ID)를 발견하여 곡의 첫부분 찾기가 완료되면 스위치(8)의 가동단자(P3)를 일측고정단자(P1)에 연결하고, 마이크로프로세서부(2)에서 메카니즘제어회로부(3)를 통해 데크메카니즘부(4)를 플레이모드로 하여 테이프를 플레이시켜 앰프부(9)를 통해 스피커(10)로 출력한다. 플레이되는 시간을 카운트하여 그 곡을 소개하는데 필요한 시간인 9초를 체크하면서 플레이되는 동안 테이프의 SUB-코드범위(SUB1-SUB2)에 기록되어 있는 곡번호를 읽어내어 그 곡에 해당하는 음성신호를 선택하도록 음성방송용메모리부(11)에 보낼 번지를 작성한 후 플레이 시간이 9초를 경과하면 스위치(8)의 가동단자(P3)를 타측고정단자(P2)에 연결하고, 상기 작성한 곡번호번지를 음성방송용메모리부(11)에 출력하여 방금 플레이한 곡의 곡 번호에 따른 곡번호음성출력을 스피커(10)를 통해 출력하도록 한다. 곡번호음성방송이 끝나면 다시 한곡을 찾게 되어 위와 같은 동작흐름을 반복하고, 곡의 첫부분을 찾지 못하면 끝을 나타내는 신호가 검출되는지를 체크하여 시작/끝검출부(5)로부터 끝신호가 검출되면 메카니즘제어회로부(3)를 통해 데크메카니즘부(4)의 모드를 되돌려감기모드로 하여 테이프를 되돌려 감은 뒤 모든 동작이 완료되게 된다.At this time, when a signal (start-ID) indicating the beginning of the song is found and the first part of the song is found, the movable terminal P3 of the switch 8 is connected to one fixed terminal P1, and the microprocessor unit 2 At this time, the deck mechanism 4 is set to the play mode through the mechanism control circuit unit 3, and the tape is played and output to the speaker 10 through the amplifier unit 9. By counting the time played and checking the 9 seconds, the time required to introduce the song, reads the song number recorded in the SUB-cord range (SUB1-SUB2) of the tape and plays the audio signal corresponding to the song while playing. After the address to be sent to the voice broadcasting memory unit 11 is selected for selection, when the play time elapses for 9 seconds, the movable terminal P3 of the switch 8 is connected to the other fixed terminal P2, and the created song number address is It outputs to the voice broadcasting memory unit 11 to output the song number voice output according to the song number of the song just played through the speaker 10. When the song number voice broadcasting is finished, one song is searched again, and the above-described operation flow is repeated. Through the control circuit unit 3, the mode of the deck mechanism unit 4 is returned to the rewind mode, and the tape is rolled back to complete all operations.

이상에서 설명한 바와 같이 본 발명은 자동차의 운전자가 사용할 때 DAT를 동작시켜 놓으면 곡소개와 함께 그 곡번호를 음성으로 들을 수 있으므로 원하는 곡의 번호를 찾기 위해 DAT세트에 시선을 돌리지 않아도 되므로 사용상에 있어 편리한 이점이 있다.As described above, according to the present invention, when the DAT is operated when the driver of the vehicle is used, the user can listen to the song number together with the song introduction, so that the user does not have to look to the DAT set to find the desired song number. There is a convenient advantage.
