Abstract: 현재 자동차의 기본오디오시스템으로 TAPE장치에 관한 것이다. 현재 자동차오디오시스템에서 TAPE장치는 자동차실내의 대시보드부분에 단 하나의 TAPE데크가 장착되어 있다. 그리하여 운전자 및 탑승자는 TAPE장치를 이용하여 노래를 듣고 싶을 때는 TAPE데크에 TAPE를 삽입하여 오디오시스템의 TAPE기능버튼 중에 재생버튼을 눌러 TAPE에 녹음되어 있는 음악 및 음성을 듣게 된다. 그리하여 자동차에는 TAPE꽂이 등이 있으며 또한 다음과 같은 불편한 점이 생긴다. 운전중이나 자동차에 탑승하였을 때 TAPE데크에 있는 TAPE가 아닌 데크외부에 있는 다른 TAPE에 있는 음악 및 음성을 듣기 위해서는 자동차대시보드에 설치되어 있는 TAPE데크에서 TAPE를 뺀 후에 다시 듣고 싶은 TAPE를 데크에 삽입하여 음악을 듣게 된다. 그리하여 이장치와 같이 TAPE를 여러개 삽입해놓고 자동차를 운전중일 때 자동차대시보드에 설치되어 있는 TAPE데크에서 TAPE를 뺀후 다시 외부에 있는 다른 TAPE를 삽입하여 노래를 듣는 것이 아니라 자동차오디오시스템의 기능중에서 TAPE를 선택하여 듣고싶은 TAPE의 음악을 듣게 된다. 이장치로 얻어지는 효과는 자동차에 TAPE체인저를 설치하게 되므로서 자동차에는 TAPE꽂이 등을 설치하여 자동차의 실내를 더럽히는 경우를 없앨 수 있으며 또한 TAPE를 자동차 아무곳이나 방치하는 것을 줄일 수 있우며 특히 자동차운전중에 카세트데크에 있는 TAPE가 아닌 다른TAPE를 듣기 위해서 TAPE를 번갈아 끼우는 불편한 점을 해소할 수 있으며 또한 자동차운전중에 TAPE를 갈아끼우는 것은 매우 위험한 일이다. 그러나 간단한 버튼조작을 통해서 다른 TAPE를들을 수 있게 되므로서 TAPE를 번갈아 끼울 때 일어날 수 있는 자동차교통사고를 확실하게 줄일 수 있게 된다.
