Scanning projection apparatus and scanning image display

A scanning projection apparatus comprising:

• a plurality of laser light sources;
• optical means each of which converts an light beam emitted from each of the plurality of laser light sources into a substantially collimated light beam or a weakly converged light beam;
• optical means which makes coincident with each other optical axes of the plurality of optical beams each converted into a substantially collimated light beam or a weakly converged light beam;
• and
• an optical reflection and scan means which drives repetitive scan of the light beams of which optical axes are made coincident in directions of two axes substantially perpendicular to each other,
• the scanning projection apparatus containing at least two or more light beams of which optical axes are made coincident and displaying a plurality of images on a projection screen by making the light beams of which optical axes are made coincident have predetermined relative angles therebetween so that the plurality of images are displayed with slight shifts of positions from each other.
