PROBLEM TO BE SOLVED: To provide such a mechanism that can surely shield noise radiated from a connector. SOLUTION: A control board 20 is secured to a main frame. A USB connector 21 and a power jack are fitted to the control board 20. A noise shielding frame 25 is attached to the main frame. A connector noise shield 25b is formed on the rear surface 25a of the noise shielding frame 25. The connector noise shield 25b is provided with a support 25d, an arm 25e, and a contact 25f. The connector noise shield 25b and a notch 26 are housed inside the main frame when the noise shielding frame 25 is fitted to the main frame. The contact 25f has an elastic force, and it is brought into contact with the side surface of the USB connector 21. Noises radiated from the USB connector 21 are shielded (absorbed) by the connector noise shield 25b. COPYRIGHT: (C)2008,JPO&INPIT
