Abstract
A projection device is adapted to be placed on a surface and includes a projection lens and a projection device housing. The projection lens is connected to the projection device housing, and the projection device housing includes a main casing and a supporting assembly disposed on the main casing in a flipping manner. When the projection device housing is located in a folded position, the supporting assembly leans against the main casing and the projection lens faces a first direction. When the projection device housing is located in an unfolded position, the supporting assembly is flipped with respect to the main casing and is adapted to stand on the surface, and the projection lens faces a second direction and is adapted to project onto the surface. The projection device may project onto the standing surface without a tall casing or a bracket to be included or additionally assembled.
