本発明は情報処理装置に係り、持にスライド式制御基抜
構成における輻射ノイズ防止対策に好適な取付け構造を
具備した情報処理装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device, and more particularly to an information processing device equipped with a mounting structure suitable for preventing radiated noise in a sliding control base configuration.
情報処理装置等の制御基板における輻射ノイズ防止対策

り輻射ノイズを減衰する等の対策方法がとられていた。Measures to prevent radiation noise in control boards of information processing equipment, etc. Conventionally, in the case of directly mounted control boards, screws are fixed at several points around the control board, as shown in Figure 8, and in the case of sliding-type husk control boards, measures are taken to prevent radiation noise. As shown in Figure 9, countermeasures have been taken, such as setting a separate piece of metal fittings on the rear of the control board, or attaching a commercially available member to the bottom of the control board to attenuate the radiated noise from that part. Ta.
しかし、ＶＣＣＩ緩和値の規制が厳しくなるにつれて上
記構造のみの対策では緩和値を満足できないと云う不具
合が生じている。However, as the regulation of the VCCI relaxation value becomes stricter, a problem has arisen in that the relaxation value cannot be satisfied with the above structure alone.

底面のみの接続である為上方向からの抑え構造を設ける
必要があるというと云う不具合があった。In the conventional technology described above, the number of screws is unnecessarily increased for a type of configuration in which several points around the control board are directly fixed with screws, and the number of screws is increased more than necessary. There is a problem with poor maintainability, and in the type of configuration where a separate piece of metal fitting is set at the rear of the sliding control board, this itself is of course a necessary countermeasure, but this alone is not sufficient to achieve sufficient effects. In addition, in the type of configuration in which general commercially available parts are attached to the bottom of the control board, the parts themselves are quite expensive, which of course leads to an increase in the total cost. Since the control board must accommodate the shape of the commercially available member, a certain degree of constraint is imposed on the control board. Furthermore, since the connection is made only at the bottom of the control board, there is a problem in that it is necessary to provide a restraining structure from above.
