PROBLEM TO BE SOLVED: To provide a unit for presentations, the unit performing the release of heat generated from a heat source with a heat sink and the like to enable the effective restriction of heat transfer to main parts including a lens, and to provide game machines comprising the unit for presentations.SOLUTION: An air duct 1126 has three ventilation routes (1671a to 1671c), at each ventilation route, a fan (1621a to 1621c) and a heat sink (1152a to 1152c) are respectively disposed. At close to a heat source, the air taken in from inlet ports with the fans is guided to exhaust ports via heat sinks, which allows the effective release of heat generated from the heat source. One ventilation route (1671b) is configured as a linear route, and the other two ventilation routes (1671a, 1671c) are configured as curved routes. |
