Claims

[Claims for Utility Model Registration] (1) A projector for projecting an image onto a screen, comprising a case, a projection table provided on the upper part of the case and having a setting surface on which an object to be projected is set, and the case. a light source provided within the case that irradiates light onto the object to be projected set on the setting surface; a lens that projects an image of the object irradiated by the light source onto the screen; and a lens that cools the inside of the case. A cooling device, a heat radiation member provided on the side of the case and having heat radiation holes for discharging cooling air from the cooling device, and a grid-like member covering the heat radiation member. A projector. (2) Utility Model Registration The projector according to claim 1, wherein the grid-like member has a higher thermal conductivity than the heat radiating member.
