DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. However, the present invention is not limited by the embodiment. As shown in FIG. 1, the television receiver 1 includes a VHF / UHF function unit 2 and a BS function unit 3
, CS function means 4, power supply means 5, CRT 6
, A video selector 7, control means 8, and operation means 9. The VHF / UHF function means 2 is
Alternatively, it is for receiving a UHF radio signal and converting it into a signal for the video. The BS function means 3 receives the radio signal of the BS and converts it into a signal for the video. The CS function means 4 is for receiving a CS radio signal and converting it into a signal for the video. The power supply means 5 includes a VHF / UHF function means 2, a BS function means 3, a CS function means 4, a CRT 6 and a video selector 7.
To supply power for operation. When the control means 8 operates the operation means 9, the power supply means
When power is supplied to all of the F / UHF function means, the BS function means and the CS function means and a predetermined time has elapsed,
Controlling the power supply means 5 so as to continue supplying power only to the means selected and used among the VHF / UHF function means, BS function means and CS function means, and to stop supplying power to other means. It is.

The operating means 9 performs operations such as power ON / OFF, channel switching, volume adjustment, sound quality adjustment, image quality adjustment, and the like.

The television receiver 1 is configured as described above. Hereinafter, functions of the television receiver 1 will be described with reference to FIG. A television viewer turns on a power switch (not shown) of the television receiver 1 to operate the television receiver 1. When the power switch is turned on, predetermined power is supplied from the power supply unit 5 to each of the VHF / UHF function unit 2, the BS function unit 3, the CS function unit 4, the power supply unit 5, the CRT 6, and the video selector 7. .

The television receiver 1 is a means selected from the VHF / UHF function means 2, the BS function means 3, and the CS function means 4 when the switch is turned off immediately before the switch is turned on, ie, for example, the BS function means If 3 has been selected, an image obtained by the functioning of the BS function means 3 is displayed on the CRT 6.

Here, when five minutes, which is a predetermined time, has elapsed since the switch was turned on, the control means 8 sends a signal to the power supply means 5.
A signal for stopping supply of power to the VHF / UHF function means 2 and the CS function means 4 is sent. Power supply means 5
Receives a signal from the control means 8 and stops supplying power to the VHF / UHF function means 2 and the CS function means 4.
On the other hand, the BS function means 3 keeps the power supply from the power supply means 5 and continues to operate. Therefore, the power supply means 5 continues to supply power only to the BS function means 3 which is selectively used, and the VHF / UHF function means 2 and the CS
Since the supply of power to the functional means 4 is stopped, useless use of power is suppressed.

Here, when the television viewer operates the operation unit 9 to adjust the image quality, the operation unit 9 sends a signal to the control unit 8. The control means 8 having received the signal from the operation means,
Not only BS function means 3 but also VHF / UHF function means 2
Also, a signal for supplying power to the CS function means 4 is output to the power supply means 5. The power supply unit 5 receiving the signal from the control unit 8 supplies a predetermined power to all of the VHF / UHF function unit 2, the BS function unit 3, and the CS function unit 4. That is, the VHF / UHF function means 2
And the CS function means 4 enters a standby state for operation.

Here, the television viewer operates the operating means 9 within 5 minutes after the adjustment of the image quality to make the VHF / UH
When the selection switching to the F function means 2 is performed, the selection of the video signal is made by the BS function means 3 to the VHF / UHF function means 2.
To the VHF / UHF function means 2
Is supplied with power from the power supply means 5 and is in a standby state, so that a predetermined operation can be immediately obtained, and no time is required for startup.

After switching the VHF / UHF function means 2 from the BS function means 3 and a predetermined time of 5 minutes has elapsed, the control means 8 supplies power to the BS function means 3 and the CS function means 4. A stop signal is sent to the power supply means 8. The power supply means 8 receiving the signal from the control means 8
Since the supply of power to the BS function means 3 and the CS function means 4 is stopped, wasteful use of power is suppressed.

In the television receiver 1, the predetermined time during which the power supply means 5 supplies power to all of the VHF / UHF function means 2, BS function means 3, and CS function means 4 is set to 5 minutes. , Can be arbitrarily selected. Also, the viewer
By operating the operation means 9 shortly before the selection switching based on the operation contents of the operation means 9, the VHF / U
When any one of the HF function unit 2, the BS function unit 3, and the CS function unit 4 is switched to another unit, it is possible to secure the start of operation of the unit newly selected.

According to the invention, when the operating means is operated, power is supplied from the power supply means to all of the VHF / UHF function means, the BS function means and the CS function means, and when a predetermined time has elapsed, the power is selectively used. By continuously supplying power only to the means that performs the power supply, it is possible to reduce unnecessary power supply during operation of the apparatus, and to reduce VHF / UHF function means, BS function means, This is a television receiver in which, when any of the CS function means is switched to any of the other means, the newly switched and selected means starts up quickly.
