Abstract

본 발명은 자동차에 장착되는 카폰과 전화번호만을 메모리하는 전화번호 메모리 카드를 접속시켜 전화번호 메모리 카드에 메모리된 전화번호를 카폰을 통해 자동으로 다이얼링 가능하도록 하여 사용의 편의성을 증대토록 한 카폰의 전화번호 메모리 카드 접속장치 그 장치를 이용한 다이얼링 방법에 관한 것이다.The present invention connects a phone number memory card that stores only a car phone and a phone number mounted on an automobile, and enables the phone number stored in the phone number memory card to be automatically dialed through the car phone, thereby increasing the convenience of use. No. Memory card connection device relates to a dialing method using the device.

이를 위해 본 발명은, 전화번호 메모리 카드가 장착되는 메모리 카드부와; 전화번호 메모리 카드의 접속 유무를 검출하는 메모리카드 접속 검출부와; 메모리카드 접속 검출부의 출력신호에 따라 메모리 카드의 접속 유무를 판단하고 키패드를 통해 입력되는 키신호에 따라 인터페이스부를 통해 메모리 카드에 저장된 전화번호를 인출하여 자동으로 다이얼링을 수행하는 마이콤과; 마이콤에서 얻어지는 전화번호를 디스플레이하는 표시부와; 마이콤에서 출력되는 전화번호에 상응하는 다이얼 톤을 발생하는 톤 발생부와; 톤 발생부에서 얻어지는 다이얼 톤을 변조하고 전력증폭하여 안테나를 통해 송신토록 하는 송신부를 구비한다.To this end, the present invention, the memory card unit is mounted memory card number; A memory card connection detector for detecting whether a telephone number memory card is connected; A microcomputer that determines whether a memory card is connected according to an output signal of the memory card connection detection unit, and automatically dials a phone number stored in the memory card through an interface unit according to a key signal input through a keypad; A display unit for displaying a telephone number obtained from the microcomputer; A tone generator for generating a dial tone corresponding to the telephone number output from the microcomputer; And a transmitting unit for modulating the dial tone obtained from the tone generating unit, amplifying the power, and transmitting the power through an antenna.

제1도는 본 발명이 적용되는 카폰의 사시도.1 is a perspective view of a car phone to which the present invention is applied.

Claims

A memory card unit 111 to which a telephone number memory card is mounted; A memory card connection detection unit 112 for detecting whether a telephone number memory card is connected or not; It is determined whether the memory card is connected according to the output signal of the memory card connection detecting unit 112, and the phone number stored in the memory card is automatically extracted through the interface unit 113 according to the key signal input through the keypad 108. A microcomputer 107 for performing dialing; A display unit (109) for displaying a telephone number obtained from the microcomputer (107); A tone generator 115 for generating a dial tone corresponding to the telephone number output from the microcomputer 107; And a transmitting unit (116) for modulating and amplifying the dial tone obtained by the tone generating unit (115) and transmitting the power through the antenna (100).

A first step of retrieving whether a memory card is connected; A second step of transmitting and receiving by operating only a car phone when the memory card is not connected and searching for a key signal applied from a keypad when the memory card is connected; A third step of, when the telephone number search signal is inputted from the searched keypad, withdraws the telephone number stored in the memory card through the interface unit and displays the retrieved telephone number sequentially on the display unit; And a fourth step of automatically dialing the selected phone number when the phone number is selected while displaying the stored phone number.
