Abstract
An electronic apparatus capable of efficiently cooling first and second circuit boards, using one cooling fan. A main circuit board is arranged substantially in parallel to a side surface of a casing. A sensor circuit board is arranged orthogonal to the side surface of the camera casing. A main duct is formed with a flow passage for cooling the main circuit board. A sensor duct has an exhaust port and is formed with a flow passage for cooling the sensor circuit board. A cooling fan is fixed to the main duct and has an exhaust port for discharging air flowing into the flow passage of the main duct. The main duct is formed with an opening connected to the exhaust port of the sensor duct, and introduces air discharged from the exhaust port of the sensor duct into the flow passage of the main duct.
