  Further, Non-Patent Document 1 discloses a technique for rotating a direct-view flat display and displaying images taken from different directions in synchronization with the rotation cycle of the flat display. However, this Non-Patent Document 1 does not disclose a configuration for displaying an image on a screen other than the display surface of a direct-view flat display that is a rotating body.

  The present invention has been made paying attention to the above-described conventional problems, and an object thereof is to provide a rotary display device capable of displaying an image by rotating a plurality of light emitting elements.

  A rotary display device according to the present invention includes a rotating body that is rotatably supported, and a plurality of light emitting elements that are arranged at least in a row in a radial direction from the rotating center on a side or a surface that is perpendicular to the rotating center of the rotating body. And a gist of the above.

According to this, it is possible to display an image by controlling light emission and non-light emission of the plurality of light emitting elements according to an image to be displayed while rotating the rotating body.
