PROBLEM TO BE SOLVED: To provide a game machine which can improve performance effects by expanding and projecting a rubber sheet into a balloon form. SOLUTION: A miniature compressor 500 performs a motion control such as feeding air into the space of a top lamp base 202 through an air injection port 203, or the taking-out/putting in air. The rubber sheet 204 expands into the balloon form and projects from a top lamp 201 in response to the motion control by the miniature compressor 500, or provides motions of a shape variation by projecting or shrinking. Therefore, performance effects by a change in the shape of the rubber sheet 204 in addition to performance processes by a light source and a sound effect generating device can be obtained.
