Abstract
본 발명은 무선 호출기에 DTMF(Dual Tone Multi Frequency) 발생기를 구비하여 무선 호출기를 통해 호출받은 사용자가 호출자의 전화번호에 해당되는 신호를 무선 호출기의 스피커를 통해 전화기의 송화기에 발생하여 전화를 걸도록 하여 무선 호출기의 사용을 더욱 편리하게 하기 위한 것으로, RF회로 및 복조회로(1), 디코더(2), 마이크로컨크롤러(3), 키입력부(4), LCD구동부(5), 부저구동부(6), 진동기(7)로 이루어진 무선 호출기에 있어서, 다이얼링기능을 설정하기 위한 다이얼링스위치(SWD)가 구비된 키입력부(10)와; 상기 디코더(2)와상기 다이얼링스위치(SWD)로부터 인가되는 신호에 따라 다이얼링을 위해 각부를 제어하는 마이크로컨트롤러(20)와; 상기 마이크로컨트롤러(20)로부터 인가되는 신호에 따라 스피커(SP)를 통해 DTMF신호를 발생하는 DTMF발생기(30)로 구성되는 것을 특징으로 하는 무선호출기의 다이얼링장치이다.The present invention is provided with a DTMF (Dual Tone Multi Frequency) generator in the wireless pager so that a user who is called through the wireless pager generates a signal corresponding to the telephone number of the caller through the speaker of the wireless pager to make a telephone call. For more convenient use of the pager, the RF circuit and the demodulation circuit (1), decoder (2), microcontroller (3), key input section (4), LCD driver (5), buzzer driver ( 6) a wireless pager comprising a vibrator (7), comprising: a key input unit (10) provided with a dialing switch (SW D ) for setting a dialing function; A microcontroller (20) for controlling each part for dialing according to a signal applied from the decoder (2) and the dialing switch (SW D ); Dialing device for a wireless pager, characterized in that composed of a DTMF generator 30 for generating a DTMF signal through the speaker (SP) in accordance with the signal applied from the microcontroller (20).
