    • A cooling mechanism for a circuit board includes a board having electronic components disposed thereon, one or more heat radiation plates disposed on the board, a cooling fan for cooling the board and the electronic components disposed on the board by blowing air to at least one of the heat radiation plates, and a metal plate attached to one end of the board to ground the board, thereby preventing the leakage of electromagnetic radiation noises from the electronic components. Further, the metal plate includes a bent portion bent in L-shape along a lateral side of the board, and the cooling fan is so disposed at the inner side of the bent portion as to be perpendicular to the board. Furthermore, an air receiving surface of the heat radiation plate is so arranged as to be oblique to an axial blowing direction of the cooling fan.
    • 电路板的冷却机构包括:具有设置在其上的电子元件的板,设置在板上的一个或多个散热板,用于冷却板的冷却风扇和通过将空气吹送到板上的至少一个 散热板和连接到板的一端的金属板以将板接地,从而防止电子部件的电磁辐射噪声的泄漏。 此外,金属板包括沿着板的侧面弯曲成L形的弯曲部分,并且冷却风扇被设置在垂直于板的弯曲部分的内侧。 此外,散热板的空气接收面被布置成与冷却风扇的轴向吹送方向倾斜。

    • A color image recorded on an original is photoelectrically read out at a first picture element interval and an image signal representing the color image is obtained. An image composing processing is carried out on the image signal under signal composing conditions determined on the basis of a desired image composition and the processed composite image signal is reproduced as a visible image on a recording material. In such an image reproducing system, a color image on an original is photoelectrically read out at a second picture element interval larger than the first picture element interval and a rough image signal is obtained. Image composing processing is carried out on the rough image signal under signal composing conditions determined on the basis of a desired image composition. The processed rough image signal is reproduced as a visible image on a display and the signal composing conditions are corrected so that the visible image on the display satisfies the desired image composition. Image composing processing is carried out on an image signal obtained by photoelectrically reading out the color image on the original at the first picture element interval under the corrected signal composing conditions.
    • 记录在原稿上的彩色图像在第一像素间隔被光电读出,并且获得表示彩色图像的图像信号。 在基于期望的图像合成确定的信号合成条件下对图像信号执行图像合成处理,并且将经处理的合成图像信号作为可见图像再现在记录材料上。 在这种图像再现系统中,原稿上的彩色图像在比第一像素间隔大的第二像素间隔被光电读出并获得粗略图像信号。 在基于所需图像组合确定的信号组合条件下对粗略图像信号进行图像合成处理。 经处理的粗图像信号作为显示器上的可视图像再现,并且校正信号组合条件,使得显示器上的可见图像满足期望的图像组成。 对通过在校正信号组合条件下以第一像素间隔对原稿上的彩色图像进行光电读取而获得的图像信号进行图像合成处理。
