The flow direction of the U-shaped forced circulation convection by the fan (11) is configured to accelerate the convection in the control section region (71) by the heat exchanger (9). Therefore, there is no deceleration or stagnation of the flow due to the collision of the two air flows, the agitation of air in the control area (71) is promoted, and the equipment cooling is improved. In particular, a large amount of heat is generated in the servo amplifier (3), and hot spots are likely to occur from the layout, but this is prevented by the suction flow to the fan (11). Also, FDD (10)
Is a component whose temperature rise is restricted to be lower than other equipment,
Since it is placed in the wind passage (73) with a high wind speed, it can be cooled sufficiently. Furthermore, the heat exchanger (9) and fan (11)
Since it is located away from the CRT (6), the CRT
(6) is not affected by the leakage magnetic flux. As described above, the present invention aims to cool the inside of the operation part (70) that is horizontally elongated and projected from the front wall (23) of the housing basic part (21) provided with the heat exchanger (9), With this configuration, the air circulation to the inside of the housing basic part (21) is impaired, and natural convection within the operating part (70) is less likely to occur, and the CRT (6), FDD
The greatest feature is that it solves the problem of poor cooling of (10) and at the same time achieves the promotion of cooling of the basic case (21) of the housing.
