    摘要： A thin type projector is disclosed. The thin type projector according to present invention includes a panel part slidingly mounted at the front surface of the housing to open and close the projection lens part selectively. The thin type projector may further include a speaker part installed at the front surface of a housing, the speaker part converting an audio input signal into sound. When the panel part is separated, a lamp as a light source is exposed to the front of the housing. As a result, a user can replace the lamp with a new one conveniently.
