7, cooling air is sent to the drive unit housing section to cool the drive units 2.

The cooling air that has cooled the power supply units 3 and 4 and the drive units 2...
After flowing in the direction of the arrow a (right side of the apparatus) along the front surface of the main bus board 41, it is guided to the various boards behind the main bus board 41. However, part of the cooling air that has cooled the power supply units 3 and 4 and the drive units 2... 2 is also guided from the right side of the device to the rear of the device. If all the cooling air is guided to the right side of the device, the flow of the cooling air on the right end side of the power supply unit accommodating section and the drive unit accommodating section deteriorates, so-called heat is stored, and the cooling for the right end side drive unit is performed. May be insufficient.

When the cooling air is guided to the rear part of the apparatus, the flow of the cooling air is once narrowed at the center of the apparatus to increase the flow velocity of the cooling air, so that the cooling air is disposed at the rear part of the apparatus. Cooling air is evenly sent to various substrates.

Claims (5)

[Claims] 1. A case accommodating a drive unit and a power supply unit, and a power switch and a display means of the power supply unit which are openably and closably attached to the case so as to open and close a power supply unit accommodation portion. A front display panel provided, and a front panel attached to the case so as to cover a front surface of the front display panel, wherein the front display panel has a through-hole for introducing outside air into the power supply unit accommodating portion. An electronic device having pores on a peripheral wall. 2. The power supply switch according to claim 1, wherein the front display panel comprises a main body containing the power switch and the display means, and a cap attached to the main body. An electronic device characterized by being formed in a rectangular parallelepiped shape in which a back surface side is opened by a rectangular front plate whose display means faces the outside and four peripheral walls. 3. The communication device according to claim 2, wherein the cap portion is attached to a back side of the main body portion so as to close the opening, and communicates with a power supply unit accommodating portion of the case. An electronic device having pores. 4. A case accommodating a drive unit and a power supply unit, and a power switch and a display means mounted on the case so as to be openable and closable so as to open and close the power supply unit housing. A front display panel provided; and a front panel attached to the case so as to cover the front of the front display panel. A power switch insulator, comprising: a switch insulator; and a part arranged along the front display panel has a double wall structure. 5. The power switch insulator according to claim 4, wherein the power switch insulator is formed by bending an electrically insulating plastic sheet.
