<P>PROBLEM TO BE SOLVED: To improve operability, in a game machine in which a player can select a performance by operating an operation means. <P>SOLUTION: At a performance display part 50a, six selective display parts 60a-60f are displayed at equal intervals along a circular virtual line segment L1, and the selective display part selected at present by the player is identified and displayed large. When the player rotates the operation means, the rotating operation is detected every time a rotation angle reaches 15 degrees. A phase angle θ<SB POS="POST">1</SB>of the rotating direction of the adjacent selective display parts 60a and 60b is 60 degrees, and when the rotating operation is detected four times, identification display is switched from the selective display part 60a to the selective display part 60b. When eight selective display parts are displayed at the performance display part 50a and the phase angle of the rotating direction of the adjacent selective display parts is 45 degrees, the identification display is switched when the rotating operation is detected three times. <P>COPYRIGHT: (C)2013,JPO&INPIT |
