え、小型化、軽量化、低価格化が強く要望されている。2. Description of the Related Art Printers, copiers, fax machines, and the like that use an electrophotographic system are designed for personal use.
There is a demand for miniaturization and weight reduction. In particular, printers that use an optical system unit that uses polygons to form an image created from digital data on an image carrier, etc.
Since it is optimal for output from a personal computer, demand for personal use is increasing, and there is a strong demand for miniaturization, weight reduction, and cost reduction.
【０００３】しかし電子写真装置は、周知のように定着
に熱を使うのが一般的であり、そのため、定着器の放熱
と、近辺の部材の熱による影響を常に考えながらこれら
小型化、軽量化を図る必要がある。However, as is well known, an electrophotographic apparatus generally uses heat for fixing. For this reason, the size and weight of the electrophotographic apparatus are reduced while always considering the heat radiation of the fixing device and the influence of the heat of members nearby. It is necessary to plan.
【０００４】そのためこういったことを配慮し、ハウジ

は射出成型したプラスチックなどの非導電性材料で作成
し、必要部分のみに金属部材を使用すると共に部品自体
も小型の部品を密に配置するような配慮を行い、軽量化
と低価格化を達成する努力がなされている。In consideration of these circumstances, members such as the housing, which are not easily affected by the heat of the fixing device, are made of a non-conductive material such as injection-molded plastic, and metal members are used only for necessary portions. In addition, efforts have been made to reduce the weight and cost of the components themselves by taking care to closely arrange small components.

保護している。However, among them, a control board for controlling the operation of the electrophotographic apparatus is fixed to a common metal plate with a power supply board for supplying power so as to avoid the influence of noise, so that a common ground and an enlarged ground area are provided. In addition, the power supply board is housed in a box-shaped sheet metal. In addition, the optical system unit is generally protected by a metal cover on the unit body in order to maintain mechanical accuracy and avoid the influence of heat.

制御などを行い、またそれ以外にも、現像開始や停止の
指示、現像用の現像バイアスの印加指示などがこの基板
から行われている。That is, the control board has a CPU for controlling the operation of the electrophotographic apparatus, and in the case of a printer, develops image data sent from a personal computer or the like in a memory, and sequentially develops the developed results to a light source for exposure. The modulated light is sent and modulated, and control is performed to form an image on the image carrier with the modulated light. In addition, instructions for starting and stopping development, and for applying a developing bias for development are also provided. It is done from the substrate.

交流バイアスなどの各種の高圧が使われており、これら
高圧が発生するノイズから制御基板をシールドしないと
誤動作の原因になる。For this reason, the malfunction of the control board may hinder the normal operation of the apparatus. On the other hand, in the electrophotographic apparatus, a DC bias of, for example, 400 V to 500 V and a peak -to- peak voltage V pp are generated during development. Various high voltages such as an AC bias of about 1.2 KV are used. Unless the control board is shielded from noise generated by these high voltages, a malfunction may occur.

電子写真装置のハウジングが非導電性の材料で作られる
ようになってハウジングを共通アースとして使えなくな
ったためである。That is, when the control board is fixed to a common metal plate with the power supply board to make the ground common and to enlarge the ground area, such noise sources are located in the same device, and the control is performed based on these influences. This is because the housing of the electrophotographic apparatus is made of a non-conductive material as described above, and the housing cannot be used as a common ground.

になる。However, in this case, since the power supply board and the control board are mounted on the same sheet metal, the degree of freedom in the layout of the main body structure and the space for accommodating the boards is reduced, which affects the miniaturization of the apparatus. The problem of giving Conversely, if the power supply board and the control board are separately installed, it is difficult to use a common ground, and it is difficult to secure a ground area, and it is difficult to shield from noise.
