Abstract

본 발명은 음량이 과도하게 설정되어 있는 상태에서 텔레비젼 수상기를 온시킬 때에 시청자가 그 음량설정상태를 인지할 수 있도록 해주는 음량제어장치에 관한 것으로서, 시청자에 의해 설정된 음량레벨을 저장하는 메모리와, 인가되는 전압레벨에 따라 음성신호를 증폭하여 출력하는 증폭수단을 갖추어, 상기 메모리에 저장된 음량레벨에 따라 상기 증폭수단의 증폭도를 제어하도록 된 텔레비젼 수상기에 있어서, 상기 메모리에 저장된 음량레벨이 일정 이상인지를 판정하는 비교수단과, 시청자에 의해 전원 온 신호가 입력되는 것을 검출하는 전원 온 신호검출수단, 상기 비교수단과 전원 온 신호검출수단으로부터의 출력신호를 논리곱하는 논리곱수단, 이 논리곱수단으로부터의 출력신호에 따라 상기 증폭수단으로 인가되는 전압레벨을 접지레벨로 스위칭하는 스위칭 수단, 상기 논리곱수단으로부터의 출력신호에 따라 시청자에게 기설정된 음량레벨을 표시해 주는 표시 제어수단 및, 상기 스위칭수단과 표시제어수단의 작동을 일정 시간동안만 유지시키는 타이머수단을 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a volume control device that enables a viewer to recognize a volume setting state when turning on a television receiver in a state where the volume is excessively set. The present invention relates to a memory for storing a volume level set by a viewer, and And amplifying means for amplifying and outputting an audio signal according to the voltage level, and controlling the amplification degree of the amplifying means according to the volume level stored in the memory. Comparison means for determining, power-on signal detection means for detecting that a power-on signal is input by the viewer, and logical-product means for ANDing the output signal from the comparison means and the power-on signal detection means, Ground level of the voltage level applied to the amplifying means according to the output signal A switching means for switching, a display control means for displaying a predetermined volume level to the viewer in accordance with an output signal from the logical product means, and a timer means for maintaining the operation of the switching means and the display control means only for a predetermined time period; Characterized in that configured.
