[Problems to be solved by the invention]

In the prior art described above, it is convenient to play a game on a handy game machine, but in addition, there are many expensive parts such as a driving IC inside the liquid crystal display device, and it is a game software. However, IC cards are constantly being updated with new software, so you need to buy new software to play a new game. Also, when playing games, it is better to spend several hours instead of playing all day. When not playing games, there is no other use, just leaving it alone, the frequency of use is quite high Absent. For the expensive shopping, you can't help but feel expensive with the game alone. Further, since the conventional liquid crystal display is of an external light reflection type, it has a drawback that it can be used only in bright places.

Therefore, in the present invention, a game machine is provided with an input terminal for a television signal, and a tuner block capable of receiving a broadcast wave of the television is formed separately, so that the game machine itself can be viewed as a television when not playing a game. And the tuner block can be connected. A game machine and a tuner block are provided.

[Means for solving the problem]

The liquid crystal display device of the present invention firstly comprises a liquid crystal display, a key switch, a power supply unit, and a case body having these components, and has a game function based on the game software read from an IC card holding the game software. And a tuner block that receives broadcast radio waves and outputs a video signal to the game machine main body block via a connection portion. The tuner block is configured to be detachable.

Second, a broadcast wave is received by a liquid crystal display device comprising a liquid crystal display, a key switch, a power supply unit, and a case body having these components and capable of executing a game function based on game software read from an IC card. A video signal is output from the tuner block via the connection portion, and a connection portion connectable to a connection portion provided on a tuner block separate from the case body is provided on the case body. An image can be displayed on the liquid crystal display based on the transmitted image signal.
