Abstract
본 발명은 오디오 카세트 레코드 등의 기기에 사용되는 일체형 수신장치에 관한 것으로 종래에는 모듈레이터 회로부, 튜너회로부 및 중간주파 회로부를 각기 별도로 구성하여 각각의 유니트내에 설치하고, 이들 회로부를 케이블 및 잭등으로 연결하였으므로 모듈레이터 회로부, 튜너회로부 및 중간주파 회로부를 각기 다른 공정으로 제작 및 생산하여 생산 설비비가 많이 들고, 많은 인력이 소모될 뿐만 아니라 생산공정이 복잡하였으며, 또한 제품의 크기를 소형화하는데 많은 지장을 주었다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an integrated receiver device used for an apparatus such as an audio cassette record. In the related art, a modulator circuit section, a tuner circuit section and an intermediate frequency circuit section are separately configured and installed in each unit, and these circuit sections are connected by cables and jacks. Modulator circuits, tuner circuits, and intermediate frequency circuits were manufactured and produced in different processes, resulting in high production equipment costs, a lot of manpower, and complicated production processes, which also contributed to the miniaturization of products.
본 발명은 모듈레이터 회로부, 튜너회로부 및 중간주파 회로부를 하나의 기판에 일체로 형성하고, 이를 실드케이스에 내장함과 아울러 각 회로부의 사이에는 실드 케이스를 설치하여 차폐시킴으로써 생산설비비 및 인력을 줄이고, 생산공정을 단순화함은 물론 제품의 크기를 소형화할 수 있다.The present invention reduces the production equipment cost and manpower by forming a modulator circuit section, a tuner circuit section and an intermediate frequency circuit section integrally on a single substrate, and embedding it in a shield case, and installing and shielding a shield case between the circuit sections. In addition to simplifying the process, the size of the product can be reduced.
