Abstract

본 발명은 차량의 주행시 현재지역의 방송주파수가 자동메모리기능에 의해 메모리부에 저장된 방송주파수와는 별도로 장거리 주행에 의한 타지역으로의 이동시 타지역의 강전계 방송주파수를 기존의 메모리밴드에 메모리 된 방송주파수를 지우지 않고 별도의 메모리밴드에 메모리시킬 수 있도록 하는 AM/FM 튜너의 메모리영역 확장시스템에 관한 것으로, AM/FM튜너를 제어하는 마이컴에 구비된 메모리부에는 현재지역에서 수신되는 강전계의 FM방송주파수가 오토 메모리기능에 의해 저장되도록 하는 FM메모리밴드와, AM방송주파수가 메모리되는 AM메모리밴드가 구비되고, 상기 마이컴에 접속된 밴드선택키이 작동에 의해 보조메모리밴드를 별도로 구비시켜 타지역에서 수신되는 강전계의 방송주파수가 메모리되도록하여 장거리 주행에 따른 수신지역이 변경 되었을때 기존의 메모리된 방송주파수를 지우지 않고도 타지역의 방송주파수를 밴드선택키이에 의해 보조메모리밴드를 별도로 구비시켜 메모리시킬 수 있도록 하므로써 기존에 메모리되어 있던 방송주파수를 지우지 않아도 되는 효과가 있다.According to the present invention, the broadcasting frequency of the current region is stored in the existing memory band when the vehicle frequency is moved to another region by long distance driving separately from the broadcasting frequency stored in the memory unit by the automatic memory function. A memory area expansion system of AM / FM tuner that allows memory to be stored in a separate memory band without erasing the broadcasting frequency. The memory part of the microcomputer controlling the AM / FM tuner includes a strong electric field received in the current region. An FM memory band for storing the FM broadcasting frequency by the auto memory function and an AM memory band for storing the AM broadcasting frequency are provided, and the band selection key connected to the microcomputer is provided with an auxiliary memory band to operate separately. The broadcasting frequency of the strong electric field received from the memory is memorized so that the receiving area When it is changed, it is possible to store the broadcasting frequencies of other regions by separately selecting the auxiliary memory band by the band selection key without erasing the existing stored broadcasting frequency, thereby eliminating the need to delete the existing broadcasting frequencies.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 따른 개략적인 블럭회로도.1 is a schematic block circuit diagram according to the present invention.

Claims

Car radio AM / FM to receive the radio frequency transmitted from the broadcasting station through the antenna 70 and amplify it through the radio frequency amplifier section, and then separates the audio frequency and the intermediate frequency through the intermediate frequency amplifier section and outputs it through the speaker 60. When the tuner 10 and the AM / FM tuner 10 are connected to the tuner 10, the band select key 30 operates for a predetermined time or more, detects this, sets an auxiliary memory band in the memory unit 50, and the memory unit 50. If the automatic memory key 40 operates in the state where the auxiliary memory band is set, the broadcast frequency is stored in the auxiliary memory band, and if the band selection key 30 operates for more than the set time, the auxiliary memory band is removed and the band selection key ( If the operation 30 is less than the set time is characterized in that the microcomputer 20 having a function to sequentially switch each memory band set in the memory unit 50 AM / FM tuner of the memory area expansion systems that.
