Disclosed is a portable game device (1) comprising a case (2) having a size approximately small enough to fit in a palm of an adult, a press-switch (5) provided on the case and serving as an operation member of an input device (4), and a turn-table adapter (10). The adapter (10) comprises a clip (11) mountable on the case (2), a shaft (12) passing through one arm (11a) of the clip, an operation disk (13) coaxially provided to the shaft (12) at on one end thereof, and a press-in disk (14) coaxially provided to the shaft (12) at another end thereof. Another arm (11b) of the clip (11) is provided with a bump (11c) to be fitted to a hole formed on the case to serve as an element necessary for assembling the game device, a bottom surface of the press-in disk (14) opposite to the press-switch is formed with a bump (11c). An integral rotation of the operation disk (13) and the press-in disk (14) allows the bump of the press-in disk to rise onto the press-switch to thereby depress the press-switch. <IMAGE> |
