Abstract
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.

A projector comprising:
- a box-shaped housing, the housing having guide protrusions at a front surface of the housing;
- a lightening part mounted at the front surface of the housing;
- a projection lens part mounted at the front surface of the housing;
- a cover part slidingly mounted at the front surface of the housing to open and close the projection lens part selectively;
