Abstract

본 발명은 씨디부를 포함하는 디씨씨부 복합 카셋트 플레이어에 있어서, 씨디부와 디씨씨부간의 데이타 입출력 및 외부 디지탈 기기와의 데이타 입출력 기술에 관한 것으로, 시스템 제어부가 입력 키이신호를 스캔하여 입력 절환용 스위치 및 출력절환용 스위치의 스위칭을 제어하고, 이에 의해 외부로부터 입력되는 디지탈신호나 디씨피의 출력 디지탈 신호가 그 입력절환용 스위치를 통해 선택되어 씨디에 기록되고, 씨디부의 출력신호나 디씨씨부의 출력신호가 출력 절환용 스위치를 통해 선택되어 외부로 출력되게 함으로써 사용자에게 편리함을 제공하고, 스위칭의 정확성을 보장하여 데이타 출동을 방지할 수 있게한 것이다.The present invention relates to a DC unit composite cassette player including a CD unit, and to a data input / output technology between a CD unit and a DC unit, and a data input / output technology with an external digital device. Controlling the switching of the output switching switch, whereby an external digital signal or output digital signal of the DC is selected through the input switching switch and recorded on the CD, and the output signal of the CD unit or the output signal of the DC unit is output. It is selected through the switching switch to be output to the outside to provide convenience to the user and to ensure the accuracy of switching to prevent data outgoing.

Claims

The digital unit 10 for processing and outputting a digital signal reproduced from a CD stored in the digital signal itself, and the digital signal output from the digital display unit 10 or the digital signal output from the digital display unit 30 A switch 21 for selecting and outputting to the outside; and a switch 22 for selecting and transmitting the digital signal output from the CD unit 10 or the digital signal D _in input from the outside to the DC unit 30. And a DC unit 30 for processing the digital signal input through the switching unit 20 and storing it in an internal recording medium or reproducing the digital signal stored in the recording medium and outputting the digital signal to the switching unit 20. And a system controller 40 for controlling the switching operation of the switching unit 20 according to an input key signal and for controlling the driving of the CD unit 10 and the DC unit 30. Player's Output selection circuit.

The first steps (S1, S2) of checking whether the digital recording mode is set in the state where the recording tee is input from the key control unit 41, and setting each part of the DC unit 30 to the recording mode when the recording mode is set. After that, it is checked whether the output signal of the CD unit 10 is in the mode of recording the DC unit 30, and the digital signal D _in or the output signal of the CD unit 10 input from the external device is the DC unit 30. The second process (S3-S6) for switching the switch 22 to be transmitted to and recorded in the meantime, and, on the other hand, if the input key is a regeneration mode key, the DC unit 30 plays back. And a third process (S7-S11) for switching the switch 21 such that the output regeneration signal of the CD unit 10 or the output regeneration signal of the CD unit 30 is output to the outside by checking the recognition. Input / output selection method of cassette player.
