<p><P>PROBLEM TO BE SOLVED: To provide a projector and optical axis adjusting method for the projector which can maintain the state where the optical axes of the various color laser beam flux coincide with each other. <P>SOLUTION: A first light source 11 and first prism 17 are unified in a first optical output unit 31, a second light source 13 and second prism 18 in a second optical output unit 32, and a third light source 15 and third prism 19 in a third optical output unit 33. The first surface 34 of the first prism 17 and the second surface 35 of the second prism 18 are adhered together with an adhesive via a first film 20, and the green laser beam passes through the first film 20 but the blue laser beam is reflected on it. The third surface 36 of the second prism 18 and the fourth surface 37 of the third prism 19 are adhered together with an adhesive through a second film 21, and the green and blue laser beams pass through the second film 21 but the red laser beam is reflected on it. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
