The recording and reproducing apparatus is provided with a plurality of information detecting contacts corresponding respectively to the information display contacts of the recording medium cassette. The supply voltage is applied via one of the information detection contacts to the corresponding information display contact. The remaining information display contacts are connected or insulated from the voltage display contacts to a supply voltage applied to signal logic "0" or logic "1" to display information by the binary code signal detected through the information detection contacts.

또, 삽입된 테이프 카세트의 상태에 대해 정보 표시 접촉부에 의해 나타난 정보를 검출하도록 간단한 구성의 정보 검출 시스템으로 제공되고, 즉, 기록 매체 카세트가 위치될 작은 크기의 테이프 카세트의 대응하는 정보 표시 접촉부가 있는 위치에 위치될 복수개의 정보 표시 접촉부와 더불어 제공된 인쇄된 배선기판, 위치될 작은 크기의 테이프 카세트의 마우쓰가 있는 위치에 위치될 마우쓰를 갖는 큰 크기의 테이브 카세트, 복수개의 정보 표시 접촉부와 더불어 제공된 인쇄된 배선 기판과 마우쓰를 갖는 작은 크기의 테이프 카세트 둘다를 사용하도록 VTR이 설계된다. 인쇄된 배선 기판은 정보 표시 접촉부가 케이스의 벽에 형성된 접촉부 슬롯을 통해 바깥측으로 부터 억세스 가능하도록 테이프 카세트의 케이스의 벽 중 하나에 고정된다. VTR은 테이프 카세트가 VTR에 삽입 될때, 각각 정보 표시 접촉부와 더불어 탄력성 있는 접촉부로 되는 탄력성 있는 정보 검출 접속부로 제공된 접속기와 더불어 제공된다.In addition, an information detecting system of a simple configuration is provided to detect the information indicated by the information display contact portion with respect to the inserted tape cassette state, that is, the corresponding information display contact portion of the small size tape cassette in which the recording medium cassette is to be placed is provided. A printed wiring board provided with a plurality of information display contacts to be positioned at a position, a large size tape cassette having a mouse to be positioned at a position of a mouse of a small size tape cassette to be positioned, a plurality of information display contacts The VTR is designed to use both the printed wiring board provided and the small sized tape cassette with a mouse. The printed wiring board is fixed to one of the walls of the case of the tape cassette such that the information display contact is accessible from the outside through a contact slot formed in the wall of the case. The VTR is provided with a connector provided as a resilient information detection connection, each of which becomes an elastic contact with the information display contact when the tape cassette is inserted into the VTR.
