[Problems to be solved by the device]

 In the above conventional technology, in the former case, many objects are connected to the main body of the game machine, and in particular, since the home TV is used as the display section, the whole apparatus becomes a large-scale object, and the portability is low. It was bad and needed a space to store it when not in use, and when it was stored separately, it was sometimes lost due to the large number of components. In addition, there are many parts that must be connected, such as AC adapters, keypads, and connection cables to TVs. Especially regarding the connection between game consoles and home TVs, the connection terminals on the home TV side are compatible with recent AV equipment. There are so many TVs that I often feel confused about how to connect them, which is not a good thing to use. Also, as the number of objects to be connected increases, the number of times of operations to attach / detach to / from the game console will increase, and the connecting parts (especially cords) and the game console will also become durable and easily broken, resulting in maintenance costs. There was also a problem. Also, since the IC card mounting part of the game console has a through hole, foreign matter such as berries, dust, and water can easily enter, so keep the IC card installed as it is. This is fine, but it is usually removed, so there is a high possibility that a foreign object will cause a malfunction or malfunction. In addition, the keypad for game operation is equipped with a large number of operation buttons, which also require delicate sensitivity and durability, but the storage state is the same as that of the game machine itself. It was harmful to the water.

Next, in the latter conventional example, it is necessary to reduce the weight in order to make it a handy type, and the liquid crystal display body must use a small one, and it is readable by game software that comes out with detailed character patches. In some cases it was not possible. In addition, since the liquid crystal display and operation keys are integrally mounted inside the game console and the IC card is also configured to be removable, the IC card remains exposed on the outer surface of the game console. There is a possibility that foreign matter such as dust, dust, or water may enter from the through hole of the mounting part, causing malfunction or malfunction.The operation keys may not move due to clogging of dust or dust, or the contact surface of the keys If there is dust or dirt in it, it could cause poor contact. Also, you cannot watch TV with this product.
