Claims

[Scope of Claim for Utility Model Registration] An operating knob that is provided on the panel on the side of the television receiver and is operated when turning on or off the power of the television receiver, and the mechanical displacement of the operating knob. A main power switch that is turned on or off in response to the main power switch, and a main power switch that is connected in series with the main power switch to the power circuit of the television receiver body, and that operates when the main power switch is turned on. an image receiving switch consisting of a relay contact that is turned on and held in the on position by mechanical displacement of a knob; and both the main power switch and the image receiving switch are turned on by mechanical displacement of the operating knob. an off-timer control circuit that processes an operation signal for an off-timer operation switch provided on the television receiver body; A power source for a television receiver, comprising: a relay drive means responsive to a control signal from the relay drive means; and a relay winding that returns the image receiving switch to an OFF position in response to a drive output from the relay drive means. On-off control circuit device.
