PROBLEM TO BE SOLVED: To provide a technique for accurately positioning a moving decoration member at a position retracted from a front face of an image display unit when the performance is not executed. SOLUTION: A game machine includes: the decoration member moving from a first position to a lower second position; two supporting members moving themselves to move the decoration member, while supporting the decoration member at two supporting parts having different distances from the center of gravity; two detecting means for detecting the two supporting members respectively positioned at a first driving area for positioning the decoration member at the first position and a second driving area for positioning the decoration member at the second position; and a drive instruction means for giving a drive instruction to two driving means which drive the two supporting members respectively and move the decoration member. When moving the decoration member to the first position, the drive instruction means provides the specific drive instructions to the two driving means, respectively, after recognizing shifting of the two supporting members from the second driving area to the first driving area based on detection values of the two detecting means.
