Abstract
A projection device including at least one projection module, at least one reflecting element, and at least one adjusting structure is provided. The projection module has at least one optical axis. The projection module is adapted to provide a projection beam. The projection beam is transmitted along a light transmission path to a projection target to form a projection image. The reflecting element is disposed between the at least one projection module and the projection target and located on the optical axis and has a reflecting surface, wherein the reflecting surface is adapted to reflect the projection beam to the projection target. The adjusting structure is connected to the projection module and the reflecting element. The adjusting structure is adapted to drive the projection module and the reflecting element to rotate along a second axis such that the projection image rotates.
