型投影機の冷却装置。A transparent heat-absorbing glass is placed in front of the light source, and the light transmitted from the light source through the heat-absorbing glass illuminates the surface of the material to be projected on the document table glass. In a reflection type projector for projecting images, a means is provided at an appropriate position on the projector body to separately generate an air flow for cooling the document table glass and an air flow for cooling the light source and the heat-absorbing glass. Cooling system for reflective projectors.
