Movie projector

A movie projector (or film projector) is an opto-mechanical device for displaying motion picture film by projecting it onto a screen. Most of the optical and mechanical elements, except for the illumination and sound devices, are present in movie cameras. Modern movie projectors are specially built video projectors (see also digital cinema).
Many projectors are specific to a particular film gauge and not all movie projectors are film projectors since the use of film is required.
