Abstract: An imaging device that is capable of causing a change in an aerial image, and can be reduced in size is provided. The imaging device includes, in a housing, a disk-shaped retro-reflection sheet in which a plurality of designs are formed at different positions, an LED light source configured to irradiate the retro-reflection sheet, a beam splitter, and a motor configured to rotate and move the retro-reflection sheet. The retro-reflection sheet is rotated and moved to enable switching of aerial images of the designs irradiated by the LED light source.
