Abstract

A dynamic film projector includes a driving mechanism having two rotation shafts parallelly extending upwardly, and a first projection assembly and a second projection assembly arranged side by side on the driving mechanism. At lease one of the first and the second projection assemblies includes: a light source, a lens assembly arranged in front of the light source, a dial having a shaft extending downwardly from a center thereof and several films fixed on the dial. The shafts connect the two rotation shafts of the driving mechanism. Lights from the one or more light sources are capable of passing through the one or more films and the lens assembly in sequence when the dial is driven by the driving mechanism to rotate. Along with continuous rotation of the dials, the patterns on the films are projected in sequence, so that the effect of continuous animation is realized.
