<P>PROBLEM TO BE SOLVED: To provide a projector capable of miniaturizing a cooling structure of a plurality of reflection type light modulation devices and reducing the inside space. <P>SOLUTION: A projector 1 is disposed at a position facing to the intersect end face intersecting with each of light incident faces 321R, 321G and 321B in a color synthesis optical device 32 and comprises a duct member 5 for blowing air to each of the reflection type light modulation devices 312. The duct member 5 comprises a duct body 7 having three air blow ducts 11 to 13 in which each one end of 11A, 12A and 13A is respectively communicated and which blow air to each of the reflection type light modulation devices 312 from another end of 11B, 12B and 13B and an introduction duct for introducing air to the duct body 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
