ク装置31を効率よく冷却できる。When the cooling fan 32 operates, air is sucked into the fan 32 from the second tunnel-shaped member 30 side and is discharged to the exhaust ports 23a and 23b through the first tunnel-shaped member 25. In this way, the cooling air flows through the second tunnel-shaped member 30 and the first tunnel-shaped member 25, and the floppy disk device 31 and the power supply components are cooled. Moreover, the cooling fan 32
Since the wall surface of the housing 11 located at the rear portion is in a hermetically sealed state, the air can efficiently flow in the second tunnel-shaped member 30 and the floppy disk device 31 can be cooled efficiently. Further, since the disk device 31 is separated from the circuit board 26 side by the support plate 29, there is no risk of being affected by heat from various circuit components arranged on the circuit board 26. Further, since the floppy disk device 31 is located upstream of the air flow with respect to the power supply component, there is no risk of being affected by heat from the power supply component. Therefore, also in this respect, the floppy disk device 31 can be efficiently cooled.
