A fan box is provided with, in addition to an intake port in the front face, a second intake port at a wall surface position upstream of a fan. An Input/output unit disposed above or below the fan box comprises an exhaust notch that is aligned with the second intake port of the fan box, as well as an intake notch that is provided further to the rear than the exhaust notch. The intake notch is in communication with an air duct that opens in the front face of the processor and that leads to a unit box. The fan discharges through an exhaust port cooling wind that has flowed into the first intake port via an operation unit, as well as cooling wind that has flowed into the second intake port via the Input/output unit.
