PROBLEM TO BE SOLVED: To provide an optical presentation device to be mounted on a game machine, capable of more realistically reproducing the presentation with light such as a rotary display lamp by a simple structure. SOLUTION: The optical presentation device comprises a reflection panel 103 revolved by a rotary motor 102 and a plurality of light emitting diodes 101a-101e disposed toward the reflection panel. By continuously controlling the light emitting diodes facing the reflection panel to be driven/lighted one after another as interlocked with the revolutionary motion of the reflection panel, presentation with the display of rotating pseudo light is executed.
