A projector apparatus utilizing wedge-type lens for projecting an image onto a surface, comprising a light source module for generating a single first light path; an illumination lens set for inputting the first light path and outputting a second light path; a reflection-type image generator for generating said image; a prism set for inputting said second light path and outputting the second light path onto the reflection-type image generator, wherein the reflection-type image generator reflects the second light path and forming a third light path carrying said image; an image projection lens set disposed on the third light path for projecting said image onto the surface, wherein the illumination lens set including a wedge-type lens working with the prism set for providing a suitable angle of incidence and angle of emission to the reflection-type image generator, the wedge-type lens lowers the required height difference, between the light axles of the illumination lens and the reflection-type image generator, and lowers the angle of emission.
