In this state, the game can be started by turning on the power switch (132) of the game device (130).

[0012]

In general, the number of household outlets in a room is not so large, and the location of the outlets is limited. The numbers are necessarily limited.

If there is no vacant home outlet (140) for connecting the game machine (130) near the television receiver (100), an AC extension cord or the like is required. Further, even when the position of the game device (130) and the household outlet (140) are not so far apart that an AC extension cord or the like is required, depending on the position of the television receiver and the outlet, the location of the game device (130) may be different. The length may be greatly limited by the length of the AC code (131) of the game device. In addition, when used in a room with a small number of outlets, it may be necessary to disconnect the AC input cord (131) of the game device from the household outlet (140) except when using the game device (130). There were drawbacks.

Further, every time a game is played, the power of the television receiver (100) and the power of the game device (130) are turned on / off.
F had to be performed separately, and the operation was complicated.

[0015]

A game key (113) for switching to a state suitable for a game, and an AC input cord (11) connected to a household outlet (140).
4).

This television receiver (200) has a game power supply terminal (201) in addition to the above-described configuration common to the conventional example.
And an AC output relay (202). The control of the AC output relay (202) is performed as shown in FIG. 3 by the channel selection microcomputer (101) which receives an input of the game key (113). Game power terminal (201) in the illustrated example
Is arranged on the front of the television receiver (200) as shown in FIG.

A remote control transmitter (121) for a television includes:
Similarly to the conventional example described with reference to FIG. 4, a game key (122) for switching the television receiver (200) to a state suitable for a game by a remote control, and a television key (20).
Power switch (12) for turning on / off the power of (0)
3).

The game device (130) also has an AC input cord (131), a power switch (132), and a video / audio output terminal (1) of the game device, as in the conventional example described with reference to FIG.
33).

A television receiver (2) according to an embodiment of the present invention
00), the AC cord (131) of the game device (130) is connected to the game power supply terminal (201) of the television receiver (200), and the video / audio output terminal ( 133) are connected to the video input terminal (107), audio Lch input terminal (108), and audio Rch input terminal (10
9) is performed. At the time of this connection, the power switch (132) of the game device (130) is turned on.

When the game mode is not entered, such as during the reception of a television broadcast, the channel selection microcomputer (101) controls the AC output relay (202) to be cut off. Therefore, even if the power switch (132) of the game device (130) is in the ON state, power is not supplied to the game device (130) from the game power terminal (201).

When the game key (113) on the main body of the television receiver (200) is pressed or the game key (122) of the remote control transmitter (121) is pressed, the remote control light receiving unit (106) receives the signal. Upon receipt, the channel selection microcomputer (101) determines that there is a game key input.

When this determination is made, the channel selection microcomputer (10
1) Switching the television receiver (200) to a state suitable for a game, outputting an AC output relay control signal (203) for conducting the AC output relay (202), and supplying power to the game device (130). To start.

The switching of the television receiver (200) to a state suitable for the game is performed in the same manner as in the conventional example described with reference to FIG. 4, by outputting the input switching control signal (120) to the input switching IC (105) and displaying the image. This is performed by outputting a video control signal (118) to the signal processing IC (103) and outputting an audio control signal (119) to the audio signal processing IC (104). As a result, the input source is switched to the video / audio output of the game device (130), and the contrast, hue, brightness, and audio of the video become suitable for the game.

Therefore, the game keys (113) (12)
Just press 2) and you will be ready to play the game.

Switching from the state in which this game can be played to the state in which television broadcasting can be viewed or the VCR can be used is performed by operating a TV channel selection key or a video key on the TV receiver main unit or the remote control transmitter. Done by

With this key operation, the channel selection microcomputer (10
1) switching the television receiver (200) to a state suitable for television broadcast reception or video signal reception,
The AC output relay (202) is turned off, and the power supply to the game device (130) is stopped. At this time, since the operation of the power switch (132) of the game device (130) is not required, the switching is easy.

Since the AC output relay (202) is controlled by the channel selection microcomputer (101), the relay is always turned on regardless of the game key input and the game power supply terminal (2) is turned on.
01), it is possible to set to always supply power, and in that case, it is also possible to connect and use an electric device other than the game device.

[0031]

As described above, the present invention provides an AC output relay (202) on the front of a television receiver (200).
Since the game power supply terminal (201) controlled by the game device (201) is provided, there is no need to secure a household outlet for connecting the game device (130), no extension cord or the like is required, and the game device (130) ) Can be prevented from being greatly limited by the length of the AC code (131) of the game machine.

In particular, according to the present invention, if a game machine is always connected and the power switch (132) of the game machine is always turned on and a game key is pressed, power is supplied to the game machine and a game can be played immediately. When the channel selection key of the television broadcast is pressed, the power supply to the game machine is cut off and the state can be shifted to the reception state of the television broadcast, so that there is an advantage that simple operability can be obtained.
