ート付テレビジヨン受像機。[Claims for Utility Model Registration] (1) Normal volume adjustment means that outputs the normal volume setting signal A and the half-mute volume setting signal B
A half-mute volume control means that outputs
When F, the signal A is output, and when this mute switch is ON, if the signal A is greater than the signal B, this signal B is output, and if this signal A is less than this signal B, this signal is output. What is claimed is: 1. A television receiver with audio mute, comprising: switching means for switching and outputting A; and audio output means, to which an audio signal is supplied, outputting audio at a volume corresponding to the output of the switching means. (2) The television receiver with audio mute according to claim 1, wherein the switching means outputs 0 when the signal A is less than or equal to the signal B.
