Abstract
A projection device for projecting images on a surface of the device includes an outer housing having a front translucent screen, a projection module frame mounted on an inner surface of the outer housing, and a projection roller frame supported by the projection module frame. The projection roller frame includes first and second spaced apart rollers rotatable respectively on two opposite cylindrical ends integrally formed on a lampshade. A cylindrical projection film is held between the first and second rollers. A light source is mounted inside the lampshade so that an image formed on the projection film can be projected on the front translucent screen by the light source. The device further includes a gear mechanism for driving the rollers, a position-limiting mechanism, and a speaker.
