PROBLEM TO BE SOLVED: To achieve presentation by light emission without degrading the visibility of a symbol display device provided around a presentation device. SOLUTION: The presentation device 40 is composed of: an LED substrate 50 having first LEDs 51 capable of irradiating the machine front face side with light, and second LEDs 52 capable of emitting light in parallel with a substrate surface; a movable body 60 forming a clearance between the movable body and the LED substrate 50 and rotated on the front side of the LED substrate 50 by driving of a driving means 53; and a cylindrical member 90 surrounding the outer periphery of the movable body 60. The projecting dimension of a peripheral wall part 91 from the LED substrate 50 is set larger than a separation dimension from the LED substrate 50 to the movable body 60, and light from the first LEDs 51 is emitted frontward from an exposed part 78 of the movable body 60, while light from the second LEDs 52 is emitted toward the outside of the movable body 60 from the clearance between the LED substrate 50 and the movable body 60 to irradiate the peripheral wall part 91.
