    • In the present invention, to provide an image reading apparatus capable to read images of document images having different gloss levels with a reproducibility suitable for uses, a data processing means is provided to irradiate a document image with light from a regular reflection light source and a diffuse reflection light source, and to generate image data based on a regular reflection output value and a diffuse reflection output value obtained from a photoelectric converting means, this data processing means obtaining gloss pixel data by comparing, based on the regular reflection correction value for shading correction of a regular reflection output value, a diffuse correction output value for shading correction of the diffuse reflection output value, and a determining threshold for determining whether or not the regular reflection output value is a gloss pixel, the corrected output value corrected by the regular reflection correction value with the determining threshold, and obtaining a non-gloss pixel data from a corrected output value corrected by the diffuse correction value.

    • A power supply circuit receives power from a power supply and supplies the power to loads including a main controller and a first sub-controller performing response action through a network when the supply of power to the main controller is blocked and the image forming apparatus is connected to the network. A second sub-controller controls the blocking of the supply of power to the main controller. The sub-controller determines whether to block the supply of power to the main controller, determines a connection state of the image forming apparatus to the network when the first determination unit determines to block the supply of power, blocks the supply of power to the first sub-control unit according to the determination result, and detects a factor for resuming the supply of power to the main controller and a factor for blocking the supply of power to all or a part of the loads.
    • 电源电路从电源接收电力,并且当向主控制器的供电被阻止并且图像形成装置被连接时,通过网络向包括主控制器和执行响应动作的第一子控制器的负载供电 到网络。 第二个子控制器控制对主控制器供电的阻塞。 子控制器确定是否阻止对主控制器的供电,当第一确定单元确定阻止电力供应时,确定图像形成设备到网络的连接状态,阻止向第一 子控制单元,并且检测恢复向主控制器供电的因素以及阻止向全部或一部分负载供电的因素。
