PROBLEM TO BE SOLVED: To reduce the area of a liquid crystal display part as much as possible so as to achieve cost reduction by arranging the respective connecting terminal parts of an operation part at a space of 90 degrees round a rectangular liquid crystal display part, and contact-connecting the connecting terminal of the main body part to one connecting terminal of the operation part so that the main body part and the operation part conduct. SOLUTION: At the time of installing a cartridge of a game software for horizontal scroll in which a game is advanced by a horizontal scroll in a game machine 21 to play the game, a main body part 23 is installed in a recessed part 31 of an operation part 24 so that a rectangular liquid crystal display part 22 is oblong. Thus, a first output terminal of the operation part 24 and an input terminal of the main body part are contact-connected to each other through a conductive rubber 35, so that the operation part 24 and the main body part 23 are put in the conducting state. Next, when the game machine 21 is held with both hands, a moving key 3 is operated by the thumb of the left hand, and a passive operation key 4a and an active operation key 4b of the operation key 4 are operated by the thumb of the right hand, the game for horizontal scroll can be enjoyed by the oblong rectangular liquid crystal display part 22. |
