본 고안은 오토 체인저 시스템에서 재생되는 CD의 종류에 따른 재생 속도 지원 장치에 관한 것으로, 오토 체인저 시스템에서 재생되는 CD의 종류에 따른 재생 속도는 일반 컴팩트 디스크(Compact Disk : 이하 CD라 칭한다)(CD-DA : 일반 디지탈 CD, 비디오 CD 등)일 때는 1배속, CD-롬 타이틀일 때는 4배속인데, 본 고안에서는 하나의 오토 체인저 시스템에서 상기와 같이 CD의 종류에 따라 서로 다른 재생 속도를 모두 지원해 주는 장치에 관한 것이다.The present invention relates to a playback speed support apparatus according to the type of CD to be played in the auto changer system, the playback speed according to the type of CD to be played in the auto changer system is referred to as a general compact disk (hereinafter referred to as CD) (CD -DA: 1x speed for general digital CDs, video CDs, etc.) and 4x speeds for CD-ROM titles. In this design, one auto changer system supports different playback speeds depending on the type of CD. The giving relates to a device.

일반적으로 종래의 오토 체인저 시스템에서는 하나의 시스템에서 한가지 종류의 CD만을 재생시켰으며, 때문에 한가지 종류의 CD에 대한 재생 속도만을 제공했다. 즉, 일반 CD를 재생시키는 오토 체인저 시스템에서는 1배속의 CD 재생 속도를, CD-롬 타이틀을 재생시키는 오토 체인저 시스템에서는 4배속의 CD 재생 속도를 지원해 주고 있었다. 그러나 현재 개발중인 하나의 오토 체인저 시스템에서 여러종류의 CD를 플레이시킬 수 있는 오토 체인저 시스템에서는 플레이시키는 CD의 종류에 따른 여러가지 재생 속도를 모두 지원해 줄 수 있어야 한다.In general, the conventional auto changer system played only one type of CD in one system, and thus provided only a playback speed for one type of CD. In other words, an auto changer system for playing normal CDs supports CD playback speeds of 1x speed, and an auto changer system for playing CD-ROM titles supports CD playback speeds of 4x. However, the auto changer system that can play several CDs in one auto changer system currently being developed should be able to support various playback speeds according to the type of CD to be played.

본 고안은 하나의 오토 체인저 시스템에서 여러 종류의 CD를 플레이시킬 수 있는 오토 체인저 시스템을 위한 것으로, 재생되는 CD의 종류에 따라 서로 다른 재생 속도를 모두 지원해 줄 수 있도록 구성한, 오토 체인저 시스템에서 재생되는 CD의 종류에 따른 재생 속도 지원 장치를 제시함을 특징으로 한다.The present invention is designed for an auto changer system that can play different types of CDs in one auto changer system, and can be played in an auto changer system that is configured to support all different playback speeds depending on the type of CD being played. It is characterized by presenting a playback speed support apparatus according to the type of CD.

즉, 전계 효과 트랜지스터를 사용하며, 재생되는 CD의 테이블 오브 콘텍(Table Of Contect : 이하 TOC라 칭한다) 정보에 의해 CD의 종류를 판단하고, 판단 결과(CD의 종류)에 따라 FET의 온/오프를 제어하도록 함으로써, 각각의 오토 체인저에서 따로 지원되던 CD 재생 속도를 하나의 오토 체인저 시스템에서 모두 지원할 수 있도록 하였다.That is, the type of CD is judged by using table effect data of a CD to be reproduced using a field effect transistor, and the FET is turned on or off according to the determination result (type of CD). By controlling the speed, the CD playback speed that was supported by each auto changer can be supported by one auto changer system.

이하 도면을 참조하여 상세히 설명하면 아래와 같다.When described in detail with reference to the drawings as follows.

제 1 도는 본 고안의 구성을 보여주는 블럭도로, 재생되는 CD의 TOC 정보를 읽어와서 고주파 신호(Radio Frequency Signal : 이하 RF라 칭한다) 증폭부(2)로 전송하는 픽-업부(1)와, 픽-업부(1)에서 입력되는 RF 신호를 증폭시켜 CD 디코더(3)로 전송하는 RF 증폭부(2)와, RF 증폭부(2)에서 입력되는 신호에 의해 재생되는 CD의 종류를 판단하여 중앙 처리 장치(4)로 전송하는 CD 디코더(3)와, CD 디코더(3)에서 입력되는 신호에 의해 FET(5)의 온/오프를 제어하는 중앙 처리 장치(4) 및, 온/오프 상태에 의해 CD 재생 속도를 지원하게 되는 FET(5)로 구성된다.1 is a block diagram showing the structure of the present invention, a pick-up unit 1 for reading TOC information of a reproduced CD and transmitting it to a radio frequency signal (hereinafter referred to as RF) amplifying unit 2; The RF amplifying unit 2 amplifies the RF signal input from the up unit 1 and transmits it to the CD decoder 3, and determines the type of CD reproduced by the signal input from the RF amplifying unit 2, The CD decoder 3 to be transmitted to the processing unit 4, the central processing unit 4 which controls the on / off of the FET 5 by the signal input from the CD decoder 3, and the on / off state. By the FET 5 which supports the CD playback speed.

상기 구성의 동작은 CD 플레이어(도면에는 도시하지 않음)에서 CD가 플레이되면, 픽-업부(1)에서 플레이되는 CD의 TOC 부분을 읽어와서 RF 증폭부(2)로 출력하고, RF 출력부(2)에서는 픽-업부(1)에서 입력된 RF 신호를 증폭하여 CD 디코더(3)로 출력하며, CD 디코더(3)에서는 RF 증폭부(2)에서 입력된 신호를 판단하여 재생되는 CD의 종류를 확인하고, 확인된 정보를 중앙 처리 장치(4)로 입력하며, 중앙 처리 장치(4)에서는 CD 디코더(3)에서 입력되는 신호에 따라 FET(5)의 온/오프를 제어하는데, 재생되는 CD가 일반 CD이면 FET(5)를 오프시켜 CD 재생 속도를 1배속으로 지원하고, 재생되는 CD가 CD-롬 타이틀이면 FET(5)를 온 시켜 CD 재생 속도를 4배속으로 지원한다. 상기에서 FET(5)의 온/오프에 따른 배속(CD 재생 속도)의 차이는 FET(5)에 연결된 캐패시터에 의해 발생하며, 캐패시터에서 제공되는 용량에 따라 배속이 달라지게 된다.When the CD is played in the CD player (not shown), the operation of the above configuration reads the TOC portion of the CD played in the pick-up unit 1 and outputs it to the RF amplifier 2, and outputs the RF output unit ( 2) amplifies the RF signal input from the pick-up unit 1 and outputs it to the CD decoder 3, and the CD decoder 3 judges the type of the CD to be reproduced by judging the signal input from the RF amplifier 2; And input the confirmed information to the central processing unit (4), and the central processing unit (4) controls the on / off of the FET (5) according to the signal input from the CD decoder (3). If the CD is a normal CD, the FET 5 is turned off to support the CD playback speed at 1x. If the CD being played is the CD-ROM title, the FET 5 is turned on to support the CD playback speed at 4x. The difference in the double speed (CD regeneration speed) according to the on / off of the FET 5 is generated by a capacitor connected to the FET 5, and the double speed varies depending on the capacity provided by the capacitor.

참고로, 상기에서 FET(5)의 수는 사용자 임의대로 결정할 수 있으며, FET(5)의 수에 따라 서로 다른 CD 재생 속도를 지원할 수 있게 된다.For reference, the number of FETs 5 can be determined by the user, and it is possible to support different CD playback speeds according to the number of FETs 5.

본 고안은 상기와 같은 오토 체인저 시스템에서 재생되는 CD의 종류에 따른 재생 속도 지원 장치를 구성하여, 서로 다른 종류의 CD 재생 속도를 하나의 오토 체인저 시스템에서 모두 지원해 줄 수 있게 하였다. 결과적으로 하나의 오토 체인저 시스템을 가지고 여러 종류의 CD를 즐길 수 있게 된 것이다.The present invention configures the playback speed support apparatus according to the type of CD to be played in the auto changer system as described above, so that it is possible to support different kinds of CD playback speeds in one auto changer system. As a result, you can enjoy several CDs with one auto changer system.
