发明名称 Image pickup apparatus with air cooling unit
摘要 An image pickup apparatus is reduced in width and length dimensions. The image pickup apparatus has a heat sink-cum-duct disposed on a rear face side of an air cooling fan. Air sucked from an opening defined by an opening portion of the heat sink-cum-duct is guided to an air inlet port of the cooling fan through a ventilation path defined by plural fins of the heat sink-cum-duct and is discharged from an air outlet port of the cooling fan. A circuit board disposed on a rear face side of the heat sink-cum-duct is cooled and heat generated in the circuit board is radiated from a heat radiation plate. The image pickup unit, cooling fan, heat sink-cum-duct, circuit board, and heat radiation plate are each formed into a flat shape having a short dimension in optical axis direction and are substantially parallel to one another.
