Abstract:
A projector provided with an optical system which optically processes luminous flux emitted from a light source and projects the magnified image on a projection surface by a projection lens, said projector comprising:a power source that supplies power to the optical system, an external case that houses said light source, said optical system and said power source, said optical system being provided with a color separation optical system to separate said luminous flux into a plurality of color luminous fluxes, a modulation system that modulates each of said separated luminous fluxes based on image information and emits the luminous flux as the modulated luminous flux, and a color synthesis optical system that synthesizes each of said modulated luminous fluxes and emits the synthesized luminous flux to said projection lens, said projection lens and said color synthesis optical system being mounted on a head plate, said head plate having a vertical wall, a support part that supports said head plate being provided in said external case, said projection lens having a base end side, said base end side of said projection lens being fixed to said vertical wall of said head plate, a bottom wall extended in the horizontal direction from a lower end part of the vertical wall, said bottom wall supports said color synthesis optical system, and a supported part supported by said support part provided in said external case, said supported part provided on said vertical wall within the height range from an upper end to a lower end of a contour of said projection lens on the vertical wall.
