However, in this configuration, the hard disk drive 114A and the control board 121A are composed of the main body frame sheet metal 131A, the first unit 132A,
The third cable 128A for performing communication between the hard disk 114A and the control board 121A transmits high-speed signals because electric noise is likely to occur due to electrical conduction through many structures such as the second unit 133A. However, there is a problem that the route becomes very long in spite of the existence.

For the reasons described above and above, the radiation noise from the third cable is very large.
As shown in FIG. 12, a cover 130A for covering the core 129A for noise suppression and the hard disk device 114A is provided on the third cable, and the space H1 between the third cable 128A and the metal object is formed as shown in FIG.

Unless 8B is removed, the hard disk drive 114B in the case 111B cannot be added or replaced.

Since the hard disk drive 114B and the control board 121B are built in the case 111B, radiated noise from the case 111B is very large.
Hard disk drive 1
There is a problem that the maintainability when adding and replacing the 14B is very poor. In order to reduce the number of screws, it is possible to attach a member such as a gasket for establishing electrical conduction between the shield cover 117B and the case sheet metal 116B, but by doing so, it is very large. This will increase costs.

Therefore, the present invention provides an image forming apparatus capable of preventing radiation noise at the time of transmitting electronic information by a cable from a hard disk to a board at a low cost and improving the workability of adding and replacing a hard disk. For the purpose of providing.
