PROBLEM TO BE SOLVED: To provide a game machine capable of simply constituting an input operation device that a player can operate easily.SOLUTION: When a player touches an arbitrary position on a surface 159a of a transparent plate 159 with fingers, the transparent plate 159 is bent slightly, thus causing output voltages of strain sensors 30a-30d disposed at four corners on a back of the transparent plate 159 to change. A detection unit acquires the respective output voltages of the four strain sensors 30a-30d, first obtains the respective strains from the respective output voltages, and detects positions (trajectories P1, P2, P3, ..., Pn) of the transparent plate 159 that the fingers have touched based on the strains. |
