Conventionally, when playing a game with a mobile phone as described above, the game can be played with a number key or a direction key (navigation key). In addition, a normal mouse can not be connected to a separate mouse or keypad, etc., even if it can be connected because it is detachable because it is always inconvenient to use.

And in mobile phones, the direction key is basically used as a direction key (navigation key) or numeric key. For example, in the case of a direction key, four directions are already displayed, so it is convenient to use. For example, use the numeric keys to specify the "4" key to the left, the "2" key to the up, the "6" key to the right, and the "5" key to the down, or a similar position. . In addition to the keys to specify the direction, generally two to three separate keys are required for the game. Also, for example, the "7" key is similarly designated and used, such as a jump and the "8" key.

However, the problem of the existing technology is that the mobile phone is getting smaller and the LCD is getting larger, the key button is relatively smaller, which causes inconvenience in key operation during the game.

The present invention was devised to solve the above problems and defects as described above, by attaching a dedicated keypad (button) that can be used during gaming on the portable terminal to be rotated horizontally by +90 degrees or -90 degrees to separate game keypads.
