PROBLEM TO BE SOLVED: To provide a video projection table for which a drainage structure is made efficient, and the efficiency for cooling a projector is improved. SOLUTION: The video projection table 200 includes the projector 40 for projecting a video; a housing 30 for accommodating the projector 40; a top plate screen 10 on which the video from the projector 40 is projected; a frame 20 for supporting the housing 30 and the top plate screen 10; a top plate drainage passage 11 disposed in the top plate screen 10, in order to drain water; and a cooling mechanism 50 for decreasing the temperature of heat generated by the projector 40, by using the liquid drained from the top drainage passage 11. The cooling mechanism 50 has a tank section 60 for storing a liquid; a drainage section 70 for draining the liquid; a pump section 80 for circulating the liquid; a water supply section 90 for supplying the liquid; a heat-conducting section, with which heat generated by the projector 40 is conducted to the tank section 60; and a control section 110 for controlling the drainage section 70, the pump section 80, and the water supply section 90.
